Abstract:
Smooth Cu nanowires were synthesized in a dual surfactant hydrothermal process using oleylamine and oleic acid. The Cu nanowires have a mean diameter of 82.3 nm and lengths >300 μm. Cu nanowire based transparent conducting electrodes were successfully fabricated with a decreased sheet resistance of 3.479 to 1.04 kΩ/sq in an increasing nanowire density with a transmittance from 94-80 %. The fabricated transparent electrode exhibits good mechanical stability with high flexibility even after 50 bending cycles. This indicates strong adhesion of the Cu nanowires on the substrate.

Abstract:
Highly ordered Ni and Ni-Cu nanowires were electrodeposited into the micropores of the porous anodic alumina (PAA) template which was fabricated by the method of two-step anodizing and the thickness of barrier layer which was formed during the anodizing process was rectified by applying current limited anodization steps. The X-ray diffration (XRD) was used to characterize the Ni and Ni-Cu nanowires and the morphology of these nanowires was examined by the way of scanning electron microscopy (SEM). The SQUID magnetometry was used to investigate the magetic properties of the nanowires. It is found that the coercivity and remanence ratio of Ni-Cu nanowire is larger than that of Ni nanowire.

Abstract:
The electrochemical conversion of carbon dioxide (CO2) into gaseous or liquid fuels has the potential to store renewable energies and reduce carbon emissions. Here, we report a three-step synthesis using Cu–Ag bimetallic nanowire arrays as catalysts for electrochemical reduction of CO2. CuO/Cu2O nanowires were first grown by thermal oxidation of copper mesh in ambient air and then reduced by annealing in the presence of hydrogen to form Cu nanowires. Cu–Ag bimetallic nanowires were then produced via galvanic replacement between Cu nanowires and the Ag+ precursor. The Cu–Ag nanowires showed enhanced catalytic performance over Cu nanowires for electrochemical reduction of CO2, which could be ascribed to the incorporation of Ag into Cu nanowires leading to suppression of hydrogen evolution. Our work provides a method for tuning the selectivity of copper nanocatalysts for CO2 reduction by controlling their composition.

Abstract:
As regards the copper oxide nanowire growth process, our experiment was consistent with the proposal of copper ions surface diffusion on a nanowire. Simply in the atmospheric pressure it is possible to synthesize CuO nanowires by annealing a copper sheet. Under a general copper oxide nanowires occurring condition, pouring the flow rate of a slight amount of air into an enclosed electric furnace in the atmospheric pressure, copper oxide nanowires adhering copper particles were synthesized on copper sheet successfully. In the growth process of the CuO wire, when the Cu substrate was heated in the air, stresses caused grain boundaries of Cu2O and CuO layers in the Cu substrate. Ultimately Cu ions formed a wire tip diffusing on the surface of a CuO wire in the vertical direction to the top surface of the CuO layer, while assembling to the tip. In this report, we describe characteristics of the structure of the CuO nanowire obtained by lowering the air flow rate.

Abstract:
Anodized aluminum oxide (AAO) films, which have numerous nanochannels ca. 75 nm in diameter, D and ca. 70 µm in length, L (ca. 933 in aspect ratio, L/D), were used as a template material for growing Co/Cu multilayered nanowire arrays. The multilayered nanowires with alternating Cu layer and Co layers were synthesized by using an electrochemical pulsed-potential deposition technique. The thickness of the Cu layer was adjusted from ca. 2 to 4 nm while that of the Co layer was regulated from ca. 13 to 51 nm by controlling the pulsed potential parameters. To get a Co/Cu multilayered nanowire in an electrochemical in-situ contact with a sputter-deposited Au thin layer, the pulsed potential deposition was continued up to ca. 5000 cycles until the nanowire reached out toward the surface of AAO template. Current-perpendicular-to-plane giant magnetoresistance (CPP-GMR) effect reached up to ca. 23.5% at room temperature in Co/Cu multilayered nanowires with ca. 3500 Co/Cu bilayers (Cu: 1.4 nm and Co: 18.8 nm). When decreasing the thickness of Co layer, the CPP-GMR value increased due to the Valet–Fert model in the long spin diffusion limit.

Abstract:
Copper (Cu) nanowire arrays embedded in anodic aluminium oxide films (AAO) on aluminium substrate have been synthesized by alternating current electrochemical deposition. Two-step anodization process has been performed to get the through-hole AAO with ordered nanochannels in 0.3[Formula: see text]M oxalic acids at DC voltages 30, 40, 50 and 60[Formula: see text]V, respectively. Structural characterization of the Cu nanowires has been analyzed by scanning electron microscopy (SEM) and X-ray diffraction (or) X-ray diffractometer (XRD). Our SEM analysis has revealed that the diameters of vertically oriented Cu nanowires are 15, 25, 45 and 60[Formula: see text]nm and the length of Cu nanowires having high packing density is about 15[Formula: see text][Formula: see text]m. XRD measurement has indicated that polycrystalline Cu nanowires prefer growth orientation along the (111) direction. Optical measurements show that reflection of the Cu nanowires/AAO on aluminium reduces with decreasing diameter of the Cu nanowires. This effect can be associated with increased light scattering from metal nanoparticles near their localized plasmon resonance frequency depending on the size and shape of the nanoparticles.

Abstract:
Highly ordered copper nanowire arrays were prepared by electrolytic deposition using porous anodic aluminum oxide (AAO) as template. The technique of removing the barrier layer of the AAO template by the pore widening procedure was investigated. The quality of the Au conducting layers sputtered at the bottom side of the AAO template was also studied. The direct current (DC) electrodeposition of copper nanowire arrays was performed efficiently above the Au layer inside the pores. The morphology of the copper nanowires was characterized by scanning electronic microscopy (SEM) and the composition of Cu nanowires was confirmed by energy dispersive X-Ray spectroscopy (EDS). The results showed that the best condition was found to be in phosphoric acid (6%wt) for 10 min to remove the barrier layer completely. Au layer was uniform and dense after sputtering for four times. Copper nanowire arrays were successfully prepared by three-electrode and two-electrode cell electro-deposition, but the nanowire arrays were more ordered by using three-electrode cell and the length of nanowires was more uniform. The diameter of a single Cu nanowire is less than 100 nm with the length up to around 10 μm, and the nanowires are well arranged in arrays.

Abstract:
Дисертаційна робота присвячена вивченню закономірностей структуроутворення 3D-систем C, Cu і Zn за умов конденсації слабопересичених парів і при використанні як класичного методу магнетронного розпилення, так і накопичувальної системи плазма-конденсат (НСПК). При використанні НСПК установлені технологічні умови формування на основі вуглецю наносфер і мікросфер, на яких у подальшому зароджуються нановолокна. Створено математичну модель, яка адекватно описує процес дозрівання за Оствальдом приблизно однакових за розміром кулястих острівців міді. На прикладі трьох серій експериментів з осадження пористих структур міді за допомогою магнетронного розпилення було показано, що основу формування пористих систем становлять малі значення пересичення осаджуваних парів, що тягнуть за собою різні швидкості нарощування конденсату в близько розміщених точках ростової поверхні. Вивчені механізми структуроутворення 3D-систем цинку при використанні як класичного методу магнетронного розпилення, так і НСПК. Установлено, що окиснені пористі конденсати цинку можуть бути використані як газові сенсори.
Диссертационная работа посвящена изучению закономерностей структурообразования 3D-систем веществ существенно различной летучести (C, Cu и Zn) в условиях околоравновесной стационарной конденсации. Осаждая конденсаты углерода в условиях, близких к термодинамическому равновесию, с помощью накопительной системы плазма-конденсат (НСПК), на начальном этапе селективного роста (в течение 6 мин) при давлении аргона 6 Па и мощности разряда 50 Вт были получены шарообразные слабосвязанные графитоподобные наноструктуры. При более продолжительной конденсации в течении нескольких часов происходит формирование графитоподобных шарообразных включений. Повышение давления рабочего газа от 6 до 10 Па при слабом изменении всех прочих технологических параметров способствует реализации более стационарного технологического процесса и зарождению на графитоподобных шарообразных включениях нановолокон. Сделано предположение о том, что в качестве активных центров зарождения углеродных нановолокон выступают изогнутые графеновые плоскости шаровидных структур. Установлено, что процесс зарождения и роста различных нановолокон разнесен во времени и определяется наличием шарообразных графитоподобных включений. Создана математическая модель массопереноса распыленного вещества в промежутке между мишенью и подложкой, адекватно описывающая процесс созревания по Оствальду островков меди приблизительно одинакового размера. На примере трех серий экспериментов по осаждению пористых структур меди при помощи магнетронного распыления было показано, что основу процесса образования пор составляют малые значения пересыщения осаждаемых паров, влекущие за собой различные скорости наращивания конденсата в близлежащих точках ростовой поверхности. Подобный селективный рост кристаллов возможен вследствие флуктуаций в распределении активных центров, при избирательной застройке кристаллографических плоскостей с максимальной энергией десорбции адатомов, а также при наличии отрицательного смещения и соответствующей фокусировке осаждаемых ионов на выступающие части ростовой поверхности. В последующем неполное сращивание кристаллов приводит к образованию пор и к появлению активных центров, необходимых для зарождения новых кристаллов. На основании анализа экспериментальных данных по получению конденсатов цинка в НСПК было выявлено существование трех зон (на диаграмме параметров «давление рабочего газа – мощность разряда») в пределах которых формируются одинаковые по характеру пористые структуры. Широкий спектр значений технологических параметров зоны 1 подтверждает процесс самоорганизации малых значений пересыщений и позволяет получать наносистемы цинка с высокой воспроизводимостью структурно-морфологических характеристик при среднем диаметре нанонитей 60 нм. При переходе в зону 2, а затем в зону 3 наблюдается постепенное увеличение пересыщения, которое подтверждается постепенным переходом к формированию структур в виде слабо связанных друг с другом системы ограненных кристаллов. Показано, что сопротивление окисленных систем цинка сильно зависит от газовой среды, в которой они находятся. Так для концентрации 0,7% пропана в воздухе, сопротивление образца снижается в 159 раз по сравнению с сопротивлением в чистом воздухе. Таким образом, полученные структуры могут найти применение в качестве газовых сенсоров, по крайней мере, к смеси пропан-бутан.
Dissertation is devoted to the investigation of the structure formation regularities of the C, Cu and Zn 3D-systems under the condensation conditions of the weakly saturated vapors and by using both the classical method of magnetron sputtering and the plasma-condensate accumulation system (PCAS). Technological conditions of the nanospheres and microspheres formation on the basis of C, on which hereafter the nanowires arise, are determined. A mathematical model that adequately describes the process of Ostwald ripening of the rounded Cu islands of the approximately equal size was created. On the example of three series of experiments on Cu porous structures deposition by using magnetron sputtering it has been shown that the small values of supersaturation of the deposited vapors, which cause different speeds of the condensate’s increase in the nearby situated growth surface points constitute the basis of the porous structures formation. Mechanisms of Zn 3D-systems structure formation by using both classical method of magnetron sputtering and PCAS are studied. It is determined that the oxidized porous zinc condensates can be used as gas sensors.

We developed the electrochemical displacement method for Cu nanowire formed by replacing the silicon and the amorphous-silicon on SiO2/Si structure with electron beam lithography. The various line width from 0.1μm to 0.2μm were patterned by e-beam resist DSE1010 exposed with dose 6mC/cm2. Oxygen-plasma treatment is used to transfer the surfaces of the e-beam resist DSE1010 from hydrophobia to hydrophilia. The width of the e-beam resist DSE1010 diluted with tolene (1:1) after 30w oxygen-plasma treatment with time 30 sec was 0.18μm. The resist flow process can reduce the line width to 78nm. Then, The copper nanowire can be fabricated by immerse the silicon and amorphous- silicon into solution mixed with cupric sulphate (CuSO4˙5H2O)with 4g/L and various HF atomic percent. We successfully fabricated Cu nanowire with a width/height of 78nm/53 nm and 98nm/68nm by replacing silicon atoms from crystal silicon wafer and amorphous-silicon, respectively.

Abstract:
This thesis is an attempt to understand ways to improve thermo-mechanical and structural properties of nano-structured materials. A detailed study on computational design and analysis of metallic nanowires is carried out. Molecular dynamic simulation method is applied. In particular, FCC metallic nanowires, NiAl, and CuZr nanowires are studied. Various bottom-up approaches are suggested with improved structural and thermo¬mechanical properties. In the first part of the thesis, Cu nanowires are considered. Existence of a novel and stable pentagonal multi-shell nanobridge structure of Cu under high strain rate tensile loading is reported. Such a structure shows enhanced mechanical properties. A three-fold pseudo-elastic-plastic shape recovery mechanism in such nanowires is established. This study also shows that the length of the pentagonal nanobridge structures can be characterized by its inelastic strain. It is also reported that an initial FCC structure is transformed into a new HCP structure. The evidence of HCP structure is confirmed with the help of experimental data published in the literature. Subsequent to the above study, a novel mechanism involving coupled temperature-stress dependent reorientation in FCC nanowires is investigated. A detailed map is generated for size dependent stress-temperature induced solid-solid reorientation in Cu nanowires. In the second part of the thesis, deformation mechanisms in NiAl based intermetallic nanowires are studied. A novel mechanism of temperature and cross-section dependent pseudo-elastic/pseudo-plastic shape and strain recovery by an initial B2 phase of NiAl nanowire is reported. Such a recoverable strain, which is as high as ~ 30%, can potentially be utilized to realize various types of shape memory and strain sensing phenomena in nano-scale devices. An asymmetry in tensile and compressive yield strength behavior is also observed, which is due to the softening and hardening of the nanowires under tensile and compressive loadings, respectively. Two different deformation mechanisms dominated by twinning under tension and slip under compression are found. Most interestingly, a superplastic behavior with a failure strain of up to 700% in the intermetallic NiAl nanowires is found to exist at a temperature of 0.36Tm. Such superplastic behavior is attributed to the transformation of the nanowire from a crystalline phase to an amorphous phase after yielding of the nanowire. In the last part the work, another type of nanowires having Cu-Zr system is considered. A novel stress induced martensitic phase transformation from an initial B2 phase to BCT phase in a CuZr nanowire under tensile loading is reported. It is further shown that such a stress induced martenistic phase transformation can be achieved under both tensile as well as compressive loadings. Tensile-compressive asymmetry in the stress-strain behavior is observed due to two different phase transformation mechanisms having maximum transformation strains of ~ 5% under compressive loading and ~ 20% under tensile loading. A size and temperature dependent tensile phase transformation in the nanowire is also observed. Small nanowires show a single step tensile phase transformation whereas the nanowires with larger size show a two step deformation mechanism via an intermediate R-phase hardening followed by R-phase yielding. A study of energetic behavior of these nanowires reveals uniform distribution of stress over the nanowire cross-section and such stress distribution can lead to a significant improvement in its thermo-mechanical properties. Similar improvement is demonstrated by designing the nanowires via manipulating the surface configuration of B2-CuZr system. It is found that the CuZr nanowires with Zr atoms at the surface sites are energetically more stable and also give a uniform distribution of stresses across the cross-section. This leads to the improvement in yield strength as well as failure strain. An approach to design energetically stable nano-structured materials via manipulating the surface configurations with improved thermo-mechanical properties is demonstrated which can help in fundamental understanding and development of similar structures with more stability and enhanced structural properties. Further ab-initio and experimental studies on the confirmation of the stability of the nanowires via manipulating the surface site is an open area of research and related future scopes are highlighted in the closure.

At present, due to the development of portable device and electric vehicles, high energy density isn’t the only purpose required. Possessing high power density is another issue which needs to be considered. An electrical device containing both high energy density and high power density will be the most wanted result. As a result, a lithium ion capacitor has been designed by using pre-lithiated germanium/copper and silicon/copper nanowire fabric for negative electrodes with activated carbon for positive electrodes. For germanium, the performance is 200 F g-1 at 0.1 A g-1. And at high current density of 100 A g-1, the capacitance can still hold about 50 F g-1. The LIC have 108 W kg-1, when the energy density is 180 W h kg-1. While low energy density, the LIC would have ultrahigh power density of 110kW kg-1. For silicon, the performance of this LIC at 0.1 g-1 is 220 F g-1, which is approximated twice of capacitance of AC in EDLCs. Even at high current density of 50 A g-1, the capacitance can still hold about 80 F g-1. At a low power density of 170 W kg-1, the energy density is as high as 208 W h kg-1. The power density increases to 75 kW kg-1, which is much higher than most results in lithium ion capacitors, while the energy density still remains at 43 W h kg-1. As a result, we believe that this device can be used in numerous applications such as electrical vehicles (EVs) and hybrid electrical vehicles (HEVs).

In this study, the multilayered CoNi/Cu nanowire arrays is prepared by using the arrays nanoporous of anodic aluminum oxide membrane as a template (AAO template ) with electrodeposition method. The diameter of AAO pores is about 250nm, 90nm and 70nm, respectively. The CoNi/Cu nanowire arrays were deposited at various electrolytic condition. The optimum electrolytic conditions had been investigated. Furthermore, we changed in non-ferromagnetic layer thickness, Co/Ni ions concentration and pore diameter of AAO, and its microcrystalline structure and magnetic properties were investigated.. The deposition rates is increased with the increasing of the electrolytic potential. CoNi alloy layers almost not be obtained as the electrolytic potential less then -0.9 V. The CoNi/Cu nanowires were deposited successfully in the electrolytic potential range of -0.9 V to -1.2 V. On the other hand, the multilayered CoNi/Cu nanowires were not grown uniformly as the electrolytic potential above -1.0 V. Therefore, the optimum electrolytic potential was determined of -1.0 V. Crystalline structure of multilayered CoNi/Cu nanowires was always fcc structure with any deposited potential for Co-Ni alloy and Cu. On the other hand, the thickness of Cu layer affect significantly on the magnetization of Co-Ni alloy layers. When the thickness of layer was above 1.5μm and had a bed magnetization. Different Co-Ni deposition potential affects not only the deposition rate of the nanowire, but also the impact of Co-Ni layers of the proportion of elements. In addition, in the control of various Co-Ni ion concentration can also adjust the ratio of elements of Co-Ni alloy layer. In the TEM analysis of the elements also proved for the continuous multilayered nanowires compose of the Co-Ni layers and Cu layers. From VSM pattern the saturate magnetization can be 11000 Oe., the easy magnetization axis are all perpendicular the nanowires, and the coercivity of multilayered CoNi/Cu nanowires are in the soft and hard magnet range. The multilayered CoNi/Cu nanowires with different Cu layer thickness, as well as Co-Ni ratio of ion concentration changes on the magnetic properties also change. Looked in the coercive, because the magnetism crystal make multilayered CoNi/Cu nanowires deviation hard magnetism the material, to this us may know in multilayered CoNi/Cu nanowires may do for outside the magnetically soft material good application, may depend on the demand affiliation in the hard magnetism aspect by the different atom content ratio alloy nanowire, synthesizes must material, regarding future on magnetic recording media its application value.

Abstract:
This study experimentally assesses single phase heat transfer characteristics of a shallow rectangular microchannel heat sink whose surface is enhanced with copper nanowires (CuNWs). The hydraulic diameter of the channel is 672 μm and the bottom wall is coated with Cu nanowires (CuNWs) of 200 nm in diameter and 50 μm in length. CuNWs are grown on the Cu heat sink by electrochemical synthesis technique which is inexpensive and readily scalable. The heat transfer and pressure drop results of CuNWs enhanced heat sink are compared with that of bare copper heat sink using deionized (DI) water as the working fluid at Reynolds Number (Re) ranging from 106–636. The experimental results indicate an enhancement in Nusselt Number (Nu) at all Re with a maximum enhancement of 24% at Re = 106. The enhanced thermal performance is attributed to two properties of Cu nanowire arrays — improvement in surface wettability characteristics and increased heat transfer surface area.

Abstract:
The polypyrrole (Ppy) is widely known as a conducting polymer, and many types of microactuators have been demonstrated based on volume change induced by oxidation-reduction reaction of polymer in liquid or dry environments. However, the thermomechanical property of Ppy is not well known. Here we report the measurement of Young’s modulus of polypyrrole nanowires and coefficient of thermal expansion (CTE) by Lateral Force Microscopy. Young’s modulus was measured via tip-deflection of a cantilevered Ppy nanowire. By measuring the applied force and deflection, the Young’s modulus was determined to be 2.3 ± 0.7 GPa. A thin metallic (Cu) film was deposited on only one side of the Ppy nanowire to form bimorph nanoactuators. The CTE was determined to be 12 × 10−6/K.

Abstract:
There is an urgent need in surface mount technology (SMT) for a nontoxic, reusable and low temperature bonding technique which can afford good mechanical support as well as electrical contact. Meanwhile in the nanotechnology, many excellent and unique structure-related properties such as the high mechanical strength, the high conductivity and the adhesion ability of gecko feet have been studied. Our lab proposes a new patterned structure of Au nanowire array named nanowire surface fastener (NSF), which cold bonding for surface mount technology can be realized at room temperature. Then various methods have been developed to fabricate nanowire, such as arc discharge, catalytic CVD growth and template synthesis, and so on. Among these methods, the template method has been widely used for preparing one-dimensional nanostructures such as metals, semiconductors, polymers, and other materials by electrochemical, electroless deposition or sol-gel technique. Especially anodic aluminum oxide template assisted way has attached considerable attention due to its unique structure properties, such as controllable pore diameter, extremely narrow pore size distribution with high densities, high aspect ratios, and ideally cylindrical pore shape. The well arranged porous anodic aluminum oxide membrane is fabricated from aluminum film by two steps zM oxalic acid electrolytes. The anodic aluminum oxide membrane was investigated for features such as pore size, interpore distance, and thickness by 40 V. It is important for fabrication of porous anodic aluminum oxide template to find out elimination of the barrier layer of oxide and the pore extending rate by 0.5 M phosphoric acid. Morphologies of surface of aluminum film between anodization process and the anodic aluminum oxide barrier layer was researched by using atomic force microscope and scanning electron microscope. Results showed that the anodic aluminum oxide having the same diameter of the pore and the well arranged pore array without branching channel was obtained. The diameter of the pore before the pore extending treatment is 42 nm and the diameter of the pore after the pore extending treatment for 30 minutes is 86 nm. It was found that the diameter of the pore increased per 15 nm by the pore extending treatment for 10 minutes. We fabricated the through-hole anodic aluminum oxide template and made Cu nanowire by the template of our own making. By using Cu nanowire, we try to produce nanowire surface fastener and evaluate its properties.
