Full textBlack carbon (BC) induces a warming effect (RFBC = +1.1 W m-2 ± 90%) through two main pathways: aerosol-radiation interaction (RFari) and aerosol-cloud interaction (RFaci). Both BC-radiation and BC-cloud interaction are affected by the mixing of black carbon with other non-refractory and non-absorbing matter present in the atmosphere. An estimation of the global radiative forcing of BC rarely accounts for internal mixing of BC while the net global cloud radiative forcing is sensitive to assumptions in the initiation of cloud glaciation, which is mostly unknown for black carbon particles. Within this thesis we investigated the variability of the light absorbing properties of black carbon, the mixing of black carbon, and the impact on light absorption and ice activation.In the first part of this thesis we investigated the spatial and seasonal variability of the mass absorption cross section (MAC) over Europe. MAC values were determined from ambient observations of elemental carbon mass concentrations (mEC) and absorption coefficients (σap). The data had been acquired during several years at different background ACTRIS supersites spread over Europe. Site specific MAC values were found to be spatially homogeneous, suggesting that the overall MAC average 9.5 ± 1.9 m2 g-1 at a wavelength of 637 nm might be representative of BC at European background locations. The MAC values showed a distinct seasonal cycle at every station. This seasonality might be related to chemical composition and aging. We observed that the MAC value has a linear and positive proportionality with the non-absorbing matter mass fraction.The second part of the work focuses on the coating acquisition of BC and the induced absorption enhancement after long-range transport. Within the CLIMSLIP (climate impact of short-lived pollutants and methane in the Arctic) project field experiments were conducted at the Zeppelin research site in Svalbard, Norway, during the Arctic spring. SP2 data were used to characterize the BC size distribution and mixing. BC containing particles having a core diameter between 170 and 280 nm were found to have a median coating thickness of 47 nm. The relationship between coating thickness and BC absorption was simulated. The observed coating thickness enhanced the mass absorption cross section by 46%, which led to a decrease of less than 1% in the single scattering albedo.In the final part of this work, the role of black carbon as ice nuclei in mixed phase clouds was investigated at the high elevation measuring site Jungfraujoch (Switzerland) during the cloud and aerosol characterization experiment (CLACE) held in 2013. The ice-CVI inlet and a single particle soot photometer were used to select and quantify the ice activated BC particles. According to the observations, BC containing particles were depleted in the ice residuals. The activation efficiency showed a size dependency, with larger BC containing particles being activated more efficiently compared to smaller ones. Activated BC cores having a diameter between 170 and 240 nm showed a larger coating thickness (median = 53 nm) compared to the total aerosol (median = 16 nm).The results obtained in this thesis shed new light on the effect of the mixing state on the optical properties and cloud activation of black carbon particles. Absorbing properties of BC showed a distinct seasonal pattern, while aging was found to consistently increase its absorption behavior. However, black carbon was found not to act as ice nuclei in low tropospheric mixed-phase clouds, where the coating thickness might play a role in the activation efficiency. This work provides freshly determined physical properties derived from ambient observations that will improve the accuracy of future aerosol and cloud radiative forcing estimations

This research integrates transparent conductive film technology and hard coating technology, with the help of optical simulation to examine (1) high hardness and high transparent substrate, (2) high hardness and transparent conductive substrate, (3) high transmittance color substrate and (4) optical attenuator substrate. (1) Using transparent hard coating aluminum nitride as a protective layer, an anti-reflection design on the front of glass substrate is conducted. Then, at the back of the glass substrate, four anti-reflection layers are coated to promote penetration. Three kinds of high hardness and high transparency substrates were constructed. In Design A, the average transparency was 98.20% and the hardness was 9 GPa. In Design B, the average transparency was 97.28% and hardness was 14 GPa, twice that of the glass substrate. In Design C, the hardness was as high as 21 GPa, three times that of the glass substrate, with the average transparency of 93%. (2) ITO was added on the four layers of anti-reflection surface to render it conductive to electricity for the construction of high hardness and transparent substrate. (3) The four layers of anti-reflection layers were replaced with color ones to construct high hardness transparent color substrate for the application of color packaging of crystalline silicon solar cells. In addition to adding colors, it allows the crystalline silicon solar cell maintain its original efficiency. (4) Using black aluminum nitride and titanium nitride in their complementary conditions of visible light transmittance, it is able to design an attenuator substrate at 20%, 10%, 5%, and 1%. After adding color layers, a black color hard coating applicable on color sunglasses was designed.

The anodized oxide film of magnesium alloy has many defects(poor bond strength, low wear and corrosion resistance, easy fading , uneven color, etc) in traditional surface coloring technology. These defects have largely limited the applications of magnesium alloy. In this paper, black ceramic film with uniform color, smooth surface, compact structure and excellent corrosion on AZ91D alloys was successfully obtained by micro-arc oxidation. Micro-arc oxidation (MAO) is a new electrochemical surface treatment technology, suitable for treating the aluminum, magnesium and titanium and other light metal alloys. In electrolyte by the arc discharge plasma generated of the substrate oxidation and high temperature melting, the film were formed with high hardness and corrosion resistance. In order to blacken the magnesium alloy AZ91D under plasma electrolytic oxidation (MAO) technology in silicate electrolyte containing copper sulfate and individual concentrations of K2FeO4, the characteristics of MAO coatings formed at different treatment time were investigated and dectection by XRD、 SEM 、XPSand color analysis instrument.

The metal-dielectric composite spectrally selective solar absorbers were widely used in solar thermal collectors due to its excellent absorption. The manufacture cost of the metal-dielectric composite spectrally selective solar absorbers is expensive and that limits its applications. In this work, the electroless composite coating technology which possesses lower cost, simple equipment and easy to operate characteristics was used to fabricate the Al2O3-black nickel composite solar selective surface on Al substrate and the Sol-gel technique was used to fabricated the anti-reflection (AR) layer. The effects of the particle size(300 nm ,70 nm , 15 nm) and content(4 g/L , 8 g/L , 16 g/L , 24 g/L , 28 g/L) of Al2O3, the thickness of the Al2O3-Black nickel composite coatings and the AR layers of SiO2 and TiO2 on the optical properties of the absorbers were investigated. The Uv/Vis/NIR spectrophotometer was utilized to measure the reflectance of the absorbers in the wavelength interval of 300 – 2500 nm, and the FTIR spectrometer was utilized to measure that in the wavelength interval of 2500 – 20000 nm. SEM and AFM were used to observe the surface morphologies and the thickness of coatings. The chemical structures of coatings were studied by ESCA. The environment durabilities including thermal stability and humidity resistance of the samples with optimized optical properties were performed.. The content of 300 nm alumina increases from 8 g/L to 28 g/L , the solar absorptance α of Al2O3-Black nickel/Al absorber increase from 0.69 to 0.79, the thermal emittance ε increase from 0.08 to 0.11. The content of 70 nm alumina increases from 8 g/L to 28 g/L , the solar absorptance α increase from 0.79 to 0.84, the thermal emittance ε increase from 0.13 to 0.20. The content of 15 nm alumina increases from 4 g/L to 16 g/L , the solar absorptance α increase from 0.81 to 0.86, the thermal emittance ε increase from 0.09 to 0.15. The 2.7 μm Al2O3-Black Nickel composite coatings contained 16 g/L of 15 nm alumina have optimum optic properties, solar absorptance α = 0.89 and low emittance ε = 0.07, and high selectivity factor 12.71. The solar absorptance and thermal emittance of the Al2O3-Black Nickel/Al absorbers with SiO2-0.5M AR layers are 0.92 and 0.09, respectively. Those of the Al2O3-Black Nickel/Al absorbers with TiO2 AR layers are 0.83 and 0.19, respectively. The selectivity factor of Al2O3-Black Nickel/Al absorbers after 300 ℃thermal stability test for 75 h decreased from 12.71 to 9.4, and that of black Nickel/Al absorbers decreased from 17 to 4.84. After 95 % humidity condensation test for 75 h, the selectivity factor of Al2O3 - Black Nickel/Al absorbers decreased from 12.71 to 4.81, and that of Black Nickel/Al absorbers decreased from 17 to 5.61.

This thesis develops a new type of three-dimensional (3D) photo-mask which can carry out sub-micrometer scaled patterning in a manner of UV beam-pen direct writing. The photo-mask fabricating method is based on silicon bulk machining, polymer replication, and most importantly, coating with a black–photoresist. Two applications have been experimentally demonstrated using the fabricated 3D photo-masks. One is for beam pen lithography (BPL) to generate complicated patterns in a mask-less manner, and the other one is to produce arrayed metallic patterns for obtaining localized surface plasmon resonance (LSPR) effects. The (3D) photo-mask along with a nano-positioning stage is applied to perform beam pen lithography. To fabricate the (3D) photo-mask, an h-PDMS mold with arrayed micro-pyramids is first replicated from a silicon mold which are prepared through standard photolithography and silicon bulk machining. The black-photoresist are then spin-coated on the h-PDMS mold. Relying on the pyramid-shaped microstructures and the coated black PR layer, it is possible to create an array of focused UV spots for UV exposure of PR layer. Experimental results show the feature size is around 400 nm, and metal micro-structures are obtained after a metal lift-off process. A BPL system is successfully constructed to produce different patterns at sub-micrometer scale, with the potential to fabricate complicate patterns in optoelectronic and semiconductor industry. For obtaining LSPR effect, a similar 3D photo-mask with pyramid-shaped cones and black-PR coated layer is fabricated but using the PUA materials. The 3D photo-mask contains hexagonally arrayed pyramid cones with a period of 1.2 μm. After photolithographic patterning and metallic lift-off, metallic nano-particles with a diameter of 400 nm disk and a diameter of 500 nm disk covering an area of 2 cm x 2 cm in size are obtained. For a gold array structures deployed on a glass substrate, a low transmittance spectrum near the wavelength of 1.6 μm and 1.7 μm due to LSPR effect is experimentally measured. The results are in good agreement with Finite element method (FEM). Based on this new method, optoelectronic devices can be designed and developed in the future.

In this research, the effect of the microporous layer composition on the anion exchange membrane fuel cell performance has been systematically investigated. In particular, two types of commercial carbon materials, acetylene black and multi-walled carbon nanotubes (MWCNT), were used to fabricate the microporous layer with polytetrafluoroethylene (PTFE) content. Different weight ratios of acetylene to MWCNT ratios of acetylene to MWCNT have been prepared and coated on the gas diffusion substrate which made up carbon fiber paper with hydrophobic treatment. Furthermore, the better air permeability and lower in-plane electric resistance were obtained from the samples with more MWCNT addition, which are due to the higher mud crack density and dimension formed on the MPL and higher electrical conductivity of MWCNT, respectively. From the surface morphology analysis, the SEM results showed that the rougher MPL surface with more and larger mud cracks was observed on the samples with higher amount of MWCNT. This can be attributed to the agglomeration of carbon nanotubes in the MPL slurry. For single AEMFC testing, the results showed that the power densities of an H2/O2 AEMFC using GDLs with coated MPL prepared by various weight ratios of acetylene to MWCNT being 1:0, 4:1, 1:1, and 1:2 were 396, 411, 518, and 354 mW/cm2, respectively. This indicated that, among prepared MPL samples, the GDL with MPL containing the 1:1 ratio of acetylene to MWCNT exhibited the best cell performance which can be ascribed to the better air permeability and electric conductivity. However, higher MWCNT addition in the MPL compared to acetylene (1:2 ratio) will form too big mud cracks on the MPL surface, which impact on the water removal and catalyst layer coating, and thereby, significantly reduce the cell performance. Thus, although the MWCNT can be beneficial for both air permeability and electric conductivity of the GDL, due to the easy agglomeration of MWCNT, the amount of MWCNT in the MPL should be carefully optimized to achieve higher cell performance.

Micro-arc oxidation (MAO) is a new electrochemical surface treatment technology, suitable for treating the aluminum, magnesium and titanium and other light metal alloys. In electrolyte by the arc discharge plasma generated of the substrate oxidation and high temperature melting, the film were formed with high hardness and corrosion resistance. In order to blacken the magnesium alloy AZ91D under plasma electrolytic oxidation (MAO) technology in silicate electrolyte containing copper sulfate, the characteristics of MAO coatings formed at different treatment time were investigated and detection by XRD, EDS, FTIR and color analysis instrument (reflectance~2%). As the color of MgO coating is gray, so it can be deduced Cu2+ as the colorants of MAO blacken process.
