The Al2O3 films were deposited onto Al2O3-TiC and Si (100) substrates by RF sputtering technique by varying powers sputter target, substrate bias voltages and fixed process pressure 25 mTorr which aim to achieve high deposition rate and investigated film properties onto different types. Result showed significant power sputter target to deposition rate both substrates and film properties depend on type of substrate. The power sputter target at 8kW and substrate bias voltage at -150 V is optimum deposition condition to provide deposition rate is 53.97nm/min for Al2O3-TiC substrate and 51.50nm/min for Si substrate. The Al2O3 film deposited onto Al2O3-TiC substrate surface morphology displayed rather roughness than Al2O3 film deposited onto Si substrate which verified from SEM and AFM as 0.99 nm (Ra) versus 0.46 nm (Ra). The film stress, hardness, reduces modulus and breakdown voltage (BDV) of Al2O3 film deposited were higher than Al2O3 film deposited on Al2O3-TiC substrates which were correspond to surface morphology.

Gold nanoparticles were synthesized and depositedin situby ultrasonic spray pyrolysis on glass and indium tin oxide (ITO) substrates. This technique led to the formation of gold nanoparticles with different morphologies without the use of any capping agent. The gold nanoparticles deposited on glass substrate were obtained as nanospheres with an average particle size of 30 nm with some agglomerates; however, the nanoparticles deposited on ITO substrate were obtained with different morphologies, such as triangular nanoprisms, nanorods, nanocubes, and nanorhombus, with particle sizes between 40 and 100 nm. The ITO substrate influenced the morphology of the gold nanoparticles obtained due to changes in the deposition temperature, which also change the crystalline structure of the ITO film on the substrate.

Binding of metal powders using electrochemically deposited binders provides a novel way of carrying metal additive manufacturing at ambient temperatures. In this paper, a mathematical model was developed to predict the hardness and the yield strength of electrochemically bound parts. In this work, an existing composite hardness model is modified to predict the deposit hardness. Experimental verification of the model was performed using brass and aluminum substrates with nickel as the binder under similar deposition parameters to verify that substrate effects were not involved in the measured hardness value. The film hardness values were then compared for deposits on both brass and aluminum substrates. The model was able to predict the hardness values on both substrates within 8% of each other thereby eliminating the substrate effects involved.

BaTiO3 thin films were deposited by metal-organic chemical vapor deposition at 840 °C on two differently treated (100) MgO single crystal substrates. One MgO substrate was only mechanically polished and the other substrate was polished and then annealed at 1100 °C for 4 h in oxygen. Observation by transmission electron microscopy showed that the BaTiO3 thin film deposited on the unannealed substrate was fine-grained and that the whole film was epitaxial (100) in nature. In contrast, the film deposited on the annealed substrate consisted of large, (100)-oriented, epitaxial grains within which were distributed (110)-oriented grains with random in-plane orientations. These differences in BaTiO3 films deposited on differently treated substrates are discussed with reference to the surface structure of the MgO substrate and nucleation kinetics of BaTiO3 thin films on MgO.

For thermoelectric thin film, the substrate plays an important role during the growing process and produces effects on its thermoelectric properties. Some special kinds of substrates provide an optimal combination of influences on both the structure and thermoelectric properties. In this work, Bi-Sb-Te films are deposited on Si substrates with different initial orientations by magnetron sputtering in two ways: with and without a pre-coating process. The preferred orientations of the Bi-Sb-Te films are greatly affected by the substrates, in which the thin film tends to deposit on Si substrate with (100) initial orientation and high (015)-texture, while the (00l)-textured Bi-Sb-Te film easily deposits on Si substrate with (110) initial orientation. The experimental and theoretical calculation results indicate that Bi-Sb-Te film with (00l)-texture presents good electrical conductivity and a higher power factor than that of film with (015)-texture.

In the present investigation, titanium (Ti), silicon carbide (SiC), silicon (Si) and tantalum (Ta) samples with the same geometry are selected as substrates to deposite HFCVD boron-doped diamond films with the same deposition parameters, using trimethyl borate as the dopant. FESEM, EDS, Raman spectroscopy and Rockwell hardness tester are used to characterize as-deposited boron-doped diamond (BDD) films. The FESEM micrographs exhibit that the film deposited on Si substrate presents the best uniformity and that on Ti substrate has smallest grain size and film thickness, with titanium element detected in the EDS spectra. Moreover, it’s speculated by indentation test that the adhesive strength between the BDD films and different substrates can be order as SiC>Ta>Ti for the different thermal expansion coefficient gaps between the substrate and diamond, and the hardness of the BDD coated samples measured using Rockwell hardness tester can also be order as SiC>Ta>Ti due to the different hardness of substrate materials. Finally, similar and representative characterization for BDD films is obtained from the Raman spectra for all the BDD films on different substrates.

Zinc oxide thin films were deposited on glass substrate at a substrate temperature of 673K by spray pyrolysis method using different concentration of 0.0125M, 0.025M and 0.05M of Zinc acetate solutions. The effect of molar concentrations on structure, surface morphology and magnetic properties of ZnO films were investigated using x-ray diffraction, scanning electron microscopy and vibrating sample magnetometer. All deposited films were polycrystalline in nature with hexagonal wurtzite structure having a preferential growth orientation along (101) plane. An improvement of crystallinity in the deposits with increasing concentration of sprayed solution was noticed. All deposit exhibit fibrous structure which increases with increase of precursor concentration solutions. At room temperature, all deposited films were shown diamagnetic character but when cooled to 5K, they have shown paramagnetic characteristics.

Silicon carbide prepared by chemical vapor deposition (CVD) is one of the important candidate materials for space mirror and high-power mirror such as laser mirror, because of its superior performances such as low density, high melting point and homogeneity. In this paper, the SiC coatings were deposited on the substrates of reaction bonded silicon carbide (RB-SiC) by CVD process. Then, the morphologies of the deposits were examined with scanning electron microscopy. The crystalline phase of the as-deposited films was confirmed with X-ray diffractometry. And the adhesion between the CVD film and the substrate was rated with scraping method. As a result, the morphologies of the deposits, i.e. whiskers at 1050°C or films at 1100°C, are different from that of the substrate. And the mean diameter of the deposits at 1100°C is larger than that at 1050°C. Furthermore, the crystalline phase of the as-deposited film is determined as β-SiC and the adhesion is firm enough not to be peeled off with the scraping test.

Cubic boron nitride (cBN) film was deposited on Co-containing WC substrates by dc jet plasma chemical vapor deposition from an Ar–N2–BF3–H2 gas system. The formation of cobalt nitrides was observed at interface, and the hindrance of Co on cBN growth was demonstrated. Growth temperature and etching treatment of the substrate before deposition influenced the cBN growth greatly. At 1050 °C, cBN films were obtained on etched substrates but not on unetched substrates. At 1090 °C, cBN films were not obtained even on etched substrates. At 960 °C, cBN films deposited even on unetched substrate but the films always peeled off after exposing to air. The film quality of cBN deposited at 960 °C is better than that deposited at 1050 °C.

Si-C-N thin films were deposited on silicon substrates by plasma-enhanced chemical vapor deposition (PECVD) using hexamethyldisilazane as the main precursor. An influence of substrate temperature (TS) on film properties was analyzed. It was established that the deposited films were x-ray amorphous. The growth of the films slows down with increasing substrate temperature. The distribution of Si–C, Si–N and C–N bonds were almost independent of TS, whereas the number of С–Н, Si–H and N–H bonds essentially decreased when substrate temperature increased. The nanohardness and elastic modulus increased with TS due to a reduction of the weak hydrogen bonds.

The application of nanowires (NWs) in solar cells (SCs) is of great interest due to their new promising aspects established in nanoelectronics. Semiconductors associated with plasmonic metal nanoparticles (NPs) such as Silver (Ag), Gold (Au) and Copper (Cu), show enhanced performance in solid state light absorbing SCs owing to plasmonic characteristic of noble metal NPs. Plasmonic NPs presented a significant role in development of visible light harvesting for many applications such as photocatalytic materials, photodynamic in Surface Enhanced Raman Spectroscopy (SERS) and photovoltaics (PVs). Integration of plasmonic NPs in semiconductor materials have opened the routes to expand new PV systems with high efficiency light absorption. In this project, we introduce the synthesis ZnO and TiO2 NWs used as N-type semiconducting substrates and various methods for isolating plasmonic metal NPs, which are later deposited on the semiconducting substrates. Vertically aligned ZnO and TiO2 NWs arrays were grown on the fluorine-doped tin oxide (FTO) conductive glass substrates via hydrothermal method at low temperature and the plasmonic NPs were synthesized by wet chemistry procedures and finally decorated on the NW films by using electrophoretic deposition.  The impact of metal NPs loaded on the ZnO and TiO2 NWs substrates was studied by means of UV-vis spectroscopy and Photoluminescence (PL) spectroscopy. The absorbance spectra of individual NPs were recorded. Remarkably, the reflectance spectra of produced samples presented an enhancement in light absorption of the substrates after uptake of NPs on the ZnO and TiO2 NWs. The optical properties of the as grown ZnO NWs films decorated with Ag NPs (I) in direct contact with substrate and (II) in presence of an Al2O3 insulating spacer layer have been investigated. Both systems exhibited an enhancement in the UV band-edge emission from the ZnO when excited at 325 nm. In contrast, the broad bend defect emission of the samples did not have a significant change compare to bare ZnO substrates. The observed results suggested that the ZnO and TiO2 NWs decorated with plasmonic nanoparticles can boost the optical properties of MOs NWs substrates and hence effectively enhance the separation of photoexcited electron-hole pairs and photo-conversion applications.

Graphene was first isolated from graphite using the method called the tape by scientists at the University of Manchester (Andre Geim, Konstantin Novoselov); such work was later awarded the Nobel Prize in Physics (2010) highlighting its innovative contribution. Still, the method of the tape or mechanical exfoliation can not provide larger domains graphene some hundred micrometers. different technologies that could promote the synthesis of continuous layers of graphene large area in order to boost the potential for large-scale applications were needed. Synthesis chemical vapor deposition (CVD) on various metal substrates is probably the method that meets the above requirements. In the CVD technique, a precursor gas is introduced into a carbon furnace where the metal substrate is placed. The gas molecule decomposes and the carbon atoms are deposited on the metal surface. There are different factors that affect the growth of graphene: the selection of the metal substrate and the thickness thereof; the growth temperature, pressure and partial pressures of the precursor gas carbon / hydrogen / argon; and finally, the growth time. Considering the synthesis of graphene, the aim of the thesis lies present new experiments and results that demonstrate the effect of H2 partial pressure, through PCH4 / PH2 ratio between gas flows, on the growth of crystals dimensional graphene and morphology. To do this, we have designed an experimental methodology consisting of three experiments: 1) Application of a hydrogen plasma to reduce the copper substrate, rather than the regular process in the presence of hydrogen. 2) In relation to the growth of graphene, we propose an optimization experiment to determine control factors for a single continuous layer of graphene and graphene large single crystal domains. 3) intended to identify the role of partial pressure ratio, / , and gas flow of hydrogen and methane have conducted experiments varying these parameters.
El grafeno fue aislado por primera vez a partir del grafito mediante el llamado método de la cinta adhesiva por científicos de la Universidad de Manchester (Andre Geim, Konstantin Novoselov); dicho trabajo fue posteriormente reconocido con el Premio Nobel en Física (2010) destacando su aportación innovadora. Aún así, el método de la cinta adhesiva o exfoliación mecánica no puede proporcionar dominios de grafeno mayores que algunos cientos de micrómetros. Eran necesarias diferentes tecnologías que pudieran promover la síntesis de capas de grafeno continuas de area grande con el fin de impulsar el potencial para aplicaciones a gran escala. La síntesis de deposición química en fase vapor (CVD) sobre diferentes sustratos metálicos es probablemente el método que cumple con los requisitos anteriores. En la técnica CVD, se introduce un gas precursor de carbono en un horno donde se coloca el sustrato metálico. La molécula de gas se descompone y los átomos de carbono se depositan sobre la superficie metálica. Existen diferentes factores que afectan el crecimiento del grafeno: la selección del sustrato del metal y el espesor de la misma; la temperatura de crecimiento, la presión, así como las presiones parciales del gas precursor del carbono / hidrógeno / argón; y, por último, el tiempo de crecimiento. Teniendo en cuenta la síntesis de grafeno, el objetivo de la tesis recae en presentar nuevos experimentos y resultados que evidencien el efecto de la presión parcial de H2, a través de la relación PCH4/PH2 entre los flujos de gas, sobre el crecimiento de cristales bidimensionales de grafeno y en su morfología. Para ello, hemos diseñado una metodología experimental que consiste en tres experimentos: 1)La aplicación de un plasma de hidrógeno para reducir el sustrato de cobre, en lugar del proceso regular en presencia de hidrógeno. 2)En relación con el crecimiento de grafeno, proponemos un experimento de optimización que determinen los factores de control para obtener una sola capa continua de grafeno y grandes dominios monocristalinos de grafeno. 3)Con la intención de identificar el papel de la relación de presiones parciales, / , y el flujo de gas de hidrógeno y metano hemos llevado a cabo experimentos de la variación de estos parámetros.

This Ph.D. thesis deals with the synthesis, immobilization of bismuth-based nanostructures and their photocatalytic evaluation for degradation of organic pollutants mainly dyes, with the aim to optimize synthesis and photo-evaluation conditions by focusing the practical application of heterogeneous photocatalysis. Initially, various bismuth based single structures α-Bi2O3, Bi5O7NO3 and heterostructures α/β-Bi2O3, β-Bi2O3/Bi5O7NO3 were synthesized by a simple and scalable route i.e. thermal decomposition of precursor salt. Properties such as crystallinity, composition, morphology and optical parameters were tuned by simply varying the calcination temperature. Heterostructures of α/β-Bi2O3, β-Bi2O3/Bi5O7NO3 are well crystallized, formed stable composites (originated from single precursor salt) and eventually improved the stability of β-Bi2O3 (a metastable form) in the heterojunction structure. Single structures and heterostructures were evaluated for photodegradation of various dyes (differ in chemical structures and ionic behaviors) under visible and UV light. Test were conducted on single dyes or mixed solution of 2/3 dyes to assess the photocatalytic mechanism and kinetics when dealing the mixed effluent. From the obtained results, it was observed that α/β-Bi2O3 and β-Bi2O3/Bi5O7NO3 heterostructures have higher photocatalytic response due to efficient cascade of electrons and holes within the tuned heterojunction and band alignments. Moreover, different dyes interact differently with the photocatalyst and resulted in changed kinetics, while mechanism of degradation depended upon their ionic behavior. Furthermore, during degradation of mixed solution; dyes that have higher interaction (with photocatalyst) and low absorptivity preferentially degraded earlier. Afterwards, α/β-Bi2O3 were used to investigate and distinguish coexisting processes during photocatalysis: (i) intense adsorption, (ii) dye photobleaching and sensitization assisted photodegradation and (iii) partial or complete mineralization. It was found that some dyes with Azo (N=N) and sulphonic groups have intense adsorption over photocatalyst surface and discoloration could occur without photocatalysis. Further, it was revealed that under controlled conditions, the other coexisted processes hardly occur during photocatalysis. Moreover, indigo carmine (IC) dye was found appropriate for preliminary photo-evaluation because its discoloration/removal process could be directly associated with photocatalytic oxidation by analyzing some identified spectral changes in UV-vis absorbance spectrum. Moreover, it was highlighted that dye chromophoric groups react readily and are easily attacked by the originated photocatalytic reactive species and partially mineralized, while further degradation of resulted intermediates containing phenyl groups, became more difficult to oxidize or reduce to achieve complete mineralization. In addition, to investigate and identify the mechanism and the path of photodegradation of the investigated dyes, two approaches were used: 1) the photo-evaluation of dyes in presence of quenchers of hole, atomic oxygen and hydroxyl radical i.e. triethyl amine (TEA), P-benzoquinone (BQ) isopropanol (IP) and, respectively and 2) Evolution of O2 after water oxidation. From the experimental results it was observed, that the photocatalytic activity eventually reduced in presence of quenchers as they quench the originated reactive radical species. Moreover, evolved O2 during water splitting confirmed that electrons and holes are well separated and able to generate reactive oxygen and radical species for photodegradation and partial mineralization of dyes. Thereafter, the work was focused to tackle the challenges of powder photocatalyst recovery and to explore a competing route, i.e. immobilized fixed support. Glass, steel mesh and sintered silica were used for photocatalyst immobilization to solve the problems associated to photocatalyst recovery, mass limitation and low interaction of pollutants with fixed photocatalyst supports. The immobilization/deposition of β-Bi2O3 over each support, was achieved by pneumatic spray pyrolysis and subsequent calcination at 450 °C. During photo-evaluation of different β-Bi2O3 immobilized supports; deposited sintered silica exhibited higher activity and competing response to β-Bi2O3 powder. The improved activity of sintered silica was associated to the rough, porous and hydrophilic nature of silica that have facilitated in providing higher interaction of deposited β-Bi2O3 films with dye molecules. Furthermore, β-Bi2O3 deposited sintered silica exhibited improved performance for photodegradation and mineralization of various dyes of different chemical structures and ionic behaviors and cyclic stability up to 3 cycles. Then, the work was focused to obtain single structure ferromagnetic bismuth ferrite (BiFeO3) and its heterostructure (BiFeO3/Fe2O3/Bi2Fe4O9); as they have the advantage of easy magnetic separation from aqueous solution. The single structure BiFeO3 and its heterostructures were obtained by using Sol-Gel method, in which precursor solution, containing dissolved Bi(NO3)3:5H2O and Fe(NO3)3:9H2O were preheated and calcined at 500°C with and without addition of Polyethylene Glycol (PEG) and NaOH in the precursor solution. From the XRD and UV-vis DRS analysis it was observed that addition of PEG and NaOH, assisted to obtain single nanostructure BiFeO3, simply by enabling the particles polymerization and inhibiting the formation of other compounds like Fe2O3 and Bi2Fe4O9. It was revealed that single phase BiFeO3 is antiferromagnetic in nature and have very low photocatalytic response, due to the low energy band gap and high electron and holes recombination rate. On the other hand, BiFeO3/Fe2O3/Bi2Fe4O9 heterostructure displayed high magnetic saturation and exhibited improved photoactivity. This is due to a low electrons and holes recombination rate because of tuned band alignment and charge transfer within the heterojunction interfaces. Cyclic stability and photocatalytic performance of BiFeO3/Fe2O3/Bi2Fe4O9 were found almost similar during photodegradation of various dyes up to 3 cycles. At the end, detailed analyses of the efficient heterostructure α/β-Bi2O3 and promising β-Bi2O3 immobilized silica were made, for the evaluation of bulk single and mixed dye solutions under natural sunlight and at varying IC dye concentrations. It was found that the mechanism and the photodegradation kinetics were almost similar amongst lab conditions and during sunlight irradiation and for bulk solutions of single and mixed dyes. Moreover, the experienced phenomena of the degradation and achieved kinetic rate at varying IC concentration were almost alike for both α/β-Bi2O3 and deposited β-Bi2O3 sintered silica. These results revealed that deposited β-Bi2O3 sintered silica could have the promising potential over α/β-Bi2O3 or any other powder photocatalyst under solar light irradiation. Moreover, cyclic stability and the photoactivity of both α/β-Bi2O3 and deposited β-Bi2O3 silica were almost identical up to 3 cycles.

Corals are the main reef builders on tropical reefs. They make their own substrate, much of which remains as consolidated rock, the remainder becoming broken down to form extensive sediment beds. Soft corals, sea fans and sponges are other major occupiers of substrate but deposit only minimal quantities of rock. All are important ecological components of coral reefs, although the greatest biodiversity of macrofauna are found amongst the fish, cryptic invertebrates and microorganisms. Amongst the algae, the microalgae symbiotic with corals are of key importance in the nutrition of the reef, but macroalgae are generally scarce on healthy reefs, partly due to grazing. Some algae generate large quantities of limestone and assist in reef construction. Growth and reduction by bioerosion are generally closely balanced in a healthy reef, and reef growth depends, of course, on growth exceeding erosion by a small margin.

Fabry disease is a rare X-linked lysosomal storage disorder in which deficiency of alpha-galactosidase A leads to accumulation of substrate, mostly globotriaosylceramide, which causes a progressive, multiorgan disease affecting predominantly the kidneys, skin, heart, and nervous system. Painful peripheral (‘acral’) neuropathy is characteristic.Key clinical signs are angiokeratoma found by close examination of skin; characteristic eye lesions may be seen; lipid deposits may be seen in urine. Renal biopsy appearances are characteristic and this is commonly where the diagnosis is first made. Increasingly, cardiologists are suspecting the condition in adults with echocardiographic appearances of left ventricular hypertrophy. Diagnosis in men is usually made by measurement of alpha-galactosidase in either white cells or plasma (or using blood spots). Unfortunately, many female patients can have normal enzyme levels so that genetic testing is the only way to confirm a diagnosis. Non-selective screening strategies (e.g. males on renal replacement therapy with uncertain renal diagnoses) have had low yields.

Fabry disease is a rare X-linked disorder of glycosphingolipid metabolism caused by a deficiency of the lysosomal acid hydrolase enzyme, alpha-galactosidase A. The resulting accumulation of substrate, mostly globotriaosylceramide, leads to a progressive, multiorgan disease affecting predominantly the kidneys, skin, heart, and nervous system. It is one of over 50 lysosomal storage diseases. It is typically diagnosed in young men after many years of ‘acral pain’ syndrome, when the diagnosis is made through identification of characteristic abnormalities of skin, kidney or heart, or of other organs. Renal failure has been a common outcome. Females may also develop manifestations, usually later in life. Renal biopsy shows vacuoles/deposits in podocytes and other renal cell types with progressive scarring. The diagnosis can be made by measuring enzyme levels in men, or by genetic testing. This latter is the more reliable test in women. Fabry disease can now be treated where affordable by regular (every 2 weeks) intravenous infusions of recombinant preparations of the deficient enzyme. These are burdensome and expensive, but are transforming the outlook for the condition.

Fabry disease is a rare X-linked lysosomal storage disorder in which deficiency of alpha-galactosidase A leads to accumulation of substrate, mostly globotriaosylceramide, which causes a progressive, multiorgan disease affecting predominantly the kidneys, skin, heart, gut, and nervous system. Painful peripheral (‘acral’) neuropathy is characteristic. The disease is commonly diagnosed in children and young men often after some years of usually neuropathic symptoms, with exacerbations (Fabry crises), that commonly elude diagnosis for a long time. These usually occur years in advance of overt involvement of other organs. Diagnosis may also be suspected from renal biopsy, echocardiographic evidence of cardiomyopathy commonly beginning as left ventricular hypertrophy, or characteristic angiokeratomas typically in ‘bathing trunk’ distribution on skin. Renal manifestations are of proteinuria leading to progressive chronic kidney disease associated with deposits in podocytes. Diarrhoea is common. Disordered sweating is typical. Corneal lesions are also typical and there may be tortuosity of retinal vessels. Strokes are increased in frequency, and sensorineural deafness may occur. Women have fewer and later overt manifestations but some develop severe disease.

AbstractAmong Additive Manufacturing technologies, Wire and Arc Additive Manufacturing process is strongly dependent of deposition conditions such as welding parameters, substrate temperature, trajectory. In this research, geometry and temperature evolutions of single beads have been investigated according to process parameters modifications. For our experiment, a heating device have been used in order to control the substrate temperature from room temperature up to 400 °C. Considering the Cold Metal Transfer technology, welding parameters, Wire Feed Speed (WFS) and Travel Speed (TS), have been modified while keeping a constant ratio λ (WFS/TS). Results indicate that weld bead geometry, height (h) and width (w), is influenced by substrate temperature and welding parameters. It has been shown that substrate temperature, itself influenced by process parameters, tends to produce thicker and lower weld beads while it increases.

Abstract Alumina splats were deposited on the polished single crystal alumina substrates with two different crystalline facet orientations of [001] and [110] by atmospheric plasma spraying (APS) at a substrate preheating temperature of 900°C to examine the epitaxy during splat cooling. The cross-sectional samples for high resolution transmission electron microscopy examination was prepared by focused ion beam assisted scanning electron microscopy (FIB-SEM). The results show that the whole splats with a thickness ranging from ~600 to ~1000nm exhibited the same crystalline structure as the substrate. Moreover, the splat deposited on the single crystalline alumina substrates exhibited exactly the same orientation as the substrate. The results evidently indicate that the epitaxial grain growth occurs after alumina droplets impact on single crystal alumina substrate. The present results suggest that the crystalline structure of alumina deposit formed by plasma spraying can be possibly controlled by the substrate preheating temperature.

A laser-induced forward transfer (LIFT) technique for transferring metal from one substrate to another has recently been reported.1 With this method, a metal film, deposited on a transparent source substrate, is irradiated by the laser which is focused at the interface between the film and substrate, Fig. 1, so that the ablated metal is expelled outward and will deposit on a target substrate located near the source. As noted previously,1 properties of the deposited metal features such as resolution, i.e., similarity of the deposited to the ablated metal region, electrical conductivity, etc., depend on a number of parameters including laser power density, film thickness, source target distance, etc.

Metallic thin films have been extensively used as coatings, interconnections, sensors and as part of micro and nano-electromechanical devices (MEMS and NEMS). The conventional substrates utilized to deposit those films are normally rigid, such as silicon. However, for applications where the substrate is subjected to significant mechanical strain (e.g. automotive coatings, electronic textiles, bioengineering, etc.) the film-substrate system needs to be flexible and conformable. Compliant polymeric substrates are ideal candidates for such a task. Some interesting mechanical properties not achieved with conventional rigid substrates can be transmitted to the film by the use of polymeric substrates. In this work, mechanical properties of 50 to 300 nm gold films deposited by thermal deposition over two thermoplastic substrates are investigated. A commercial thermoplastic, Polysulfone (“PSF”), and a home-synthesized isophthalic polyester based on the reaction of 4, 4′-(1-hydroxyphenylidene) phenol and isophthaloyl dichloride (“BAP”) [1] were used as raw materials for substrate production. Substrates were selected based on their good mechanical properties and flexibility. The use of two different substrates allows us to investigate the influence of the substrate mechanical properties in the bimaterial response. Substrates of 80 μm thickness were prepared by solution casting and cut to rectangular shapes of nominal dimensions of 30 mm × 5 mm. High purity (99.999%) commercial gold splatters were used for film deposition. Gold films with thickness of 50, 100, 200, and 300 nm were deposited onto PSF substrates by thermal evaporation inside a vacuum chamber at 3×10−5 Torr. Au films with 100 nm thickness were also deposited over BAP substrates. Four replicates of each type were deposited (at the same time) and used for tensile testing. Tensile testing of Au/PSF (film thickness 50–300 nm) and Au/BAP (film thickness 100 nm) specimens was conducted. Tests of the neat PSF and BAP substrates (6 replicates) were also conducted as a baseline. Tensile testing was conducted in a small universal testing machine with a load cell of 200 N and a cross head speed of 0.05 mm/min. The film mechanical properties were extracted from the tensile response of the film/substrate system, considered as a bimaterial. Based on sum of forces and strain compatibility, the film modulus (Ef) and stress (σf) can be extracted from characteristics of the bimaterial (EBim, σBim) and substrate (Es, σs), to generate a stress-strain curve for the film, see e.g. [2], Ef=1Af[ABimEBim−AsEs]=1+tstfEBim−tstfEs(1a)σf=1Af[P−Ps]=1+tstfσBim−tstfσs(1b) where P is the applied load, A = wt is the cross sectional area and sub-index “Bim” corresponds to the film-substrate bimaterial (ABim = w(ts+tf)). Figure 1 shows film stress (σ)-strain (ε) representative curves for Au films with different thicknesses extracted from the Au/PSF bimaterials. The film behavior presents only a small region of plasticity close to the ultimate strain. Thus, the numerical value of the maximum stress (strength) is close to its yield strength. The large plasticity of the substrate may hinder the plasticity of gold when acting as a bimaterial. As observed from this figure, the film modulus, strength and ultimate strain increase as the film thickness decreases, evidencing a “thickness-effect” not observed in bulk materials. Slightly different properties were obtained for the Au films deposited over the BAP substrate, which evidences some substrate-dependency of the film properties.

Abstract High quality coatings of titanium can be obtained by cold spraying using high process gas temperatures and pressures. However, the performance of cold sprayed coatings is determined not only by the respective material properties and the impact conditions, but also by the temperature and properties of the substrate—including the already deposited— material. In the present study, cold spray of spherical titanium grade II powders was performed on titanium grade II, copper, and stainless steel substrates, using two sets of parameters and three different substrate temperatures. Single impacts and respective particle adhesion were investigated using wipe tests followed by a modified cavitation test. Higher bond strengths were achieved for substrates that were held at higher temperatures during spraying. Moreover, the electrical conductivity of coating, taken as a measure of particle-particle bonding quality within the coating, improved and the porosity decreased for increased substrate temperatures. The findings are discussed in view of the thermal conditions, as well as the mechanical response of the uppermost layer of the substrate/deposit set.

Abstract Cold spray deposition of polycarbonate on the various substrates has been investigated. The polycarbonate particles are sieved and accelerated at elevated temperature in air through a DeLaval type nozzle, and are deposited on the metallic and ceramic substrates. The influences of the particle size, the gas temperature, the thermal conductivity and surface roughness of substrate on the deposition process are studied. As a result, the continuous deposits are formed on the metallic substrate. The powder sieved below 300 μm shows better deposition efficiency. Thin film of melted polycarbonate has been formed on the surface of substrate to act as a bonding layer, and its crystalline structure is changed to be amorphous, which is the more stable state for the polycarbonate. The coating seems to be better when the thermal conductivity of metallic substrate is low. For the ceramic substrates, there is no deposition whatever was the thermal conductivity.

Abstract New concept and method of testing for the interconnecting porosity of thermally sprayed nonconductive ceramic coatings is proposed. This process is useful to differentiate the open porosity from the closed porosity. Thermally sprayed ceramic coating with metallic substrate is plated, and the intergranular gaps in the coating are filled by deposited metal. Typically, 304 stainless steel substrate deposited with atmospheric plasma sprayed alumina coating is immersed in copper(II) sulphate bath, and electroplated. Inward of the alumina coating, plating solution penetrates toward the interface of coating/substrate via interconnected porosity, and attains the coating-substrate interface to deposit metallic copper. Deposit of copper is gradually grown up along the coating intergranular. The exposure of deposited copper on the coating surface can be visible. Because these phenomena occur only in the interconnected pore structure, it is easy to differentiate the interconnected porosity from the closed porosity. Also the proposed process suggests the unprecedented possibility of manufacturing method of three-dimensional structure of thermally sprayed ceramic coating.

Abstract Deposition of a dense coating with solid particles by cold spraying requires sufficient deformation of impacting particles and previously deposited underlying particles. The cermet particles and subsequent coating with a high hardness are difficult to deform upon impact. To increase the ability of deformation, the cermet spray particles with a porous structure design is proposed to fulfill the requirements of deformation on impact. To understand the deposition mechanism, the deposition behavior of single WC-Co spray particles impacting on the substrates with different hardnesses during cold spraying were examined using WC-12Co powders with different porosity. The substrates include stainless steel, nickel-based self-fluxing alloy coatings were employed to examine the effect of substrate deformation on the cermet particle deposition. It was found that using two porous powder of the porosity of 30% and 44% the WC-Co cermet particles were deposited on the substrate of different hardness from 200Hv to 800Hv. The deposition of the particles is mainly attributed to the deformation of powders themselves. The properly designed porous cermet powder with certain hardness is necessary condition to deposit hard WC-Co cermet coating.

Dust particles carry microbial and chemical signatures from source regions to deposition regions. Dust and its occupying microorganisms are incorporated into, and can alter, snowpack physical properties including snow structure and resultant radiative and mechanical properties that in turn affect larger-scale properties, including surrounding hydrology and maneuverability. Microorganisms attached to deposited dust maintain genetic evidence of source substrates and can be potentially used as bio-sensors. The objective of this study was to investigate the impact of dust-associated microbial deposition on snowpack and microstructure. As part of this effort, we characterized the microbial communities deposited through dust transport, examined dust provenance, and identified the microscale location and fate of dust within a changing snow matrix. We found dust characteristics varied with deposition event and that dust particles were generally embedded in the snow grains, with a small fraction of the dust particles residing on the exterior of the snow matrix. Dust deposition appears to retard expected late season snow grain growth. Both bacteria and fungi were identified in the collected snow samples.
