Summary: This study shows that the dehydrogenation activation energy of MgH2 can be lowered by incorporating ceria, but the ceria undergoes phase transformations during dehydrogenation. It also suggests that reduced cerium oxide phases may be mistaken as cerium hydrides, therefore the belief in CeH2 as an active catalyst in the MgH2/CeO2 hydrogen storage system needs further scrutiny.

Summary: The effects of La3+ and Al3+ substitution on the structural, dielectric, and piezo-electric properties of (1-x)(K0.5Bi0.5)TiO3-xLaAlO3 ceramics were investigated. With the increase in LAO content, a decrement in tetragonal distortion and an increase in cubic symmetry were observed. The incorporation of LAO in KBT resulted in an improved relaxor behavior and a suppression of oxygen vacancies. The piezo-electric properties were enhanced, with the 3% LAO-doped sample exhibiting the highest piezo-electric charge coefficient and improved piezo-electric voltage coefficient. An energy harvesting experiment was performed on the poled 3% LAO-doped ceramic, showing promising results under normal finger tapping.

Summary: This study demonstrates that ruthenium nanoparticles decorated on TiO2 nanomaterials with different morphologies show high efficiency and selectivity for the allylic oxidation of cycloalkenes. The Ru/TiO2 nanofibers display the highest activity, while Ru/TiO2 nanoparticles and nanotubes also exhibit good conversion rates. The catalytic efficiency of Ru/TiO2 nanomaterials is higher compared to Ru NPs and TiO2 nanomaterials individually, indicating a positive synergistic effect. The results suggest that the crystalline structure, pore volume, and surface area of the supports play a role in determining the activity of Ru/TiO2 NPs and NFs.

Summary: Ti2O3 thin films were prepared by atomic layer deposition and their electrical resistivity was measured as a function of temperature. The films remained stable for up to three weeks and showed an insulator-metal transition at around 80 K, with a significant change in resistivity. The anomalous increase in resistivity in the films is consistent with the two-band model and is dependent on the crystallographic c/a ratio.

Summary: 1,3-Dialkyl imidazolium salts are versatile ionic liquids (ILs) that can function as solvents, supports, or modifiers for catalytic processes. They can modify the properties of catalysts and control the access of substrates and expulsion of products. The miscibility, hydrophobicity, ionicity, and basicity of ILs can be adjusted by choosing the appropriate alkyl side chain and anions, allowing fine-tuning of the catalytic system. ILs also offer the possibility of designing greener catalytic tools and various methods for product separation.

Summary: Chemical fixation of CO2 to epoxides is an efficient and environmentally friendly approach to produce cyclic carbonates. By using the n-butyl-3-methylimidazulim trichlorozincate (BMIm.ZnCl3) ionic liquid as catalyst, high conversion rates (56-95%) of different aromatic and aliphatic epoxides were achieved under ambient reaction conditions. The activity of the catalyst was further enhanced by supporting the IL on SiO2, resulting in a maximum conversion and yield (99%) of cyclic carbonates at higher reaction conditions. The reaction mechanism was found to involve strong hydrogen bonding between the epoxide oxygen and the C2-H of the imidazolium cation, with the ZnCl3 anion acting as a nucleophile to facilitate ring opening without dissociation.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
