Summary: The refractive index of SiOxNy thin film is controlled by changing the N2 and Ar flow ratio in 13.56 MHz RF-ICP. The density of N2+ and the refractive index of the thin film increase as the gas ratio [N2/(N2+Ar)] increases from 0.1 to 0.9. The results show that N2+ plays an important role in changing the properties of thin film during the plasma process.

Summary: Monolithic support materials with the mechanical resistance and thermal conductivity of SiC, as well as tunable surface chemistry and textural properties, have been developed for use in catalytic membrane reactors. The skin applied onto the external wall and the infiltration of metal oxide nanoparticles into macropores allow for the immobilization of liquid phase catalysts. The resulting multimodal distribution of pore sizes can be tuned by various factors such as particle sizes, wash-coats, and calcination temperature.

Summary: Tungsten oxide WO3 thin films are deposited using DC reactive magnetron sputtering, and a unique zigzag columnar structure is achieved through the Reactive Gas Pulsing Process (RGPP) and Glancing Angle Deposition method (GLAD). Optical properties such as refractive index, extinction coefficient, and absorption coefficient are tuned by adjusting the number of zigzags in the structure, with absorption and extinction coefficients decreasing as the number of zigzags increases. The lowest refractive index is observed at the highest tilt angle of 85 degrees, while the highest refractive index is obtained at a zigzag number close to four, indicating a correlation between microstructure changes and optimized optical properties.

Summary: In this study, a series of Pd catalysts supported on commercially available activated carbon (Norit(R)) were prepared using different metal precursors (Pd(NO3)2 and Na2PdCl4) at different pH. The best catalytic activity and small particle size were achieved for the Pd/C sample prepared with Pd(NO3)2 salt impregnated at pH = 2.5 and reduced with sodium borohydride. The catalytic activity was found to be size-dependent and a mixture of surface Pd0 and PdII oxidation states was beneficial for the activity.

Summary: This work presents the preparation of a series of Pd catalysts on a CNx support for the liquid phase decomposition of formic acid. The resulting catalysts showed high activity due to factors such as small particle size, appropriate Pd0/PdII ratio, nitrogen content, and testing conditions. The study also found that the catalyst was activated after use, which was attributed to the variation of surface Pd oxidation states under the effect of formic acid/sodium formate solutions.

Summary: The microstructure and composition of Si-He nanocomposite films deposited by magnetron sputtering (MS) with different operation modes were compared. The films exhibited different depth compositions, nanopore size and shape distributions, porosity, and He content depending on deposition conditions. The presence of impurities promoted He diffusivity and reduced He accumulation. The release of He occurred at temperatures ranging from 473-723 K without film crystallization, and films grown in RF mode remained stable up to 573 and 723 K for 4He and 3He content respectively.

Summary: The formation of monoclinic VO2 crystal domains at low temperatures in nanocolumnar vanadium/oxygen thin films deposited via magnetron sputtering is analyzed. The synthesis involved depositing amorphous nanocolumnar VO1.9 thin films at room temperature and annealing them at temperatures between 250 - 330 ? in an oxygen atmosphere. The nanocolumnar structures exhibited a thermochromic transition at 47 ? (for annealing at 270 ?) and 58 ? (for annealing at 280 and 290 ?), resulting in a significant drop in optical transmittance in the infrared region.

Summary: The r-process is successful in explaining the abundance distributions of heavy elements in ultra-metal poor stars, but it fails to account for the overabundances observed in elements with atomic number 26 < Z < 47. An additional source of nucleosynthesis, known as the weak r-process, occurring in neutrino-driven winds of core-collapse supernovae, has been proposed. This study focuses on improving the certainty of nucleosynthesis predictions by measuring the cross section of the Kr-86(alpha,n)Sr-89 reaction at energy relevant to the weak r-process, using a novel solid helium target and the EMMA recoil mass spectrometer and TIGRESS gamma-ray spectrometer at TRIUMF.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
