Summary: In this study, a simple process combining sol-gel deposition and nano-templating with polycarbonate membranes was developed to synthesize interconnected nanotube networks of silica. The size and porosity of the nanotube walls could be controlled by adjusting the ethanol amount and the presence of a porogen agent during synthesis.

Summary: This paper demonstrates that the structure, morphology, and optical properties of TiO2 inverse opals can be precisely controlled by changing the synthesis conditions. Opal photonic crystals were fabricated using self-assembly-based vertical deposition technique, and TiO2 precursor was synthesized by mixing ethanol, HCl, and selected ratios of titanium tetra isopropoxide (TTIP). Different amounts of the precursor were injected into the opal structures, and the effects on crack-free and uniform structures on a micro-scale were discussed. The study provides valuable insights for choosing the optimal synthesis conditions for different TiO2 inverse opal applications.

Summary: Silica hollow microspheres were prepared as biocompatible cell carriers using emulsified gelatin microspheres as sacrificial templates. SEM observations showed their spherical morphology with a hollow structure and a diameter of 50-200 μm. FT-IR spectrum revealed the presence of Si-O-Si bonds. Gelatin microspheres served as supporting matrix and sacrificial templates for the formation of hollow structure. The silica hollow microspheres were found to be biocompatible and supported cell attachment and proliferation when seeded with osteoblast MC3T3-E1 cells, indicating their potential as biocompatible cell carriers.

Summary: Living in risky environments and having a risky occupation can affect risk-tolerance. Despite the involvement of dopamine in reward expectation, genetic studies have not found a conclusive link between dopaminergic genes and risk attitudes. This study explores the possibility that the DRD4-7R allele's effect on risk-taking behavior is influenced by environmental factors. The results show that the increase in risk-tolerance caused by the 7R allele is independent of environmental risk in two populations in Northern Senegal, one of which is exposed to a very high risk due to dangerous fishing.

Summary: Platinum nanoparticles supported by titania can form overlayer due to strong metal-support interaction, which can enhance the catalyst's properties and prevent sintering. The overlayer can be reversed through oxidative treatments, but recent findings suggest its stability in oxygen. In our study, we used in situ transmission electron microscopy to investigate the changes in the overlayer under different conditions and found that high temperature and oxygen atmosphere preserved the overlayer, preventing platinum evaporation.

Summary: Metal-organic frameworks (MOFs) containing noble metal nanocrystals (NCs) show great potential in catalysis, especially for selective catalysis. However, the crystalline framework shell of MOFs can hinder the mass transfer and diffusion of precursors, leading to suboptimal catalytic performance.

Summary: Direct conversion of carboxylic acids to alkanes by decarboxylation on PdHx is improved by anchoring the carboxylate group with K+ on PdHx/C, which increases the rate of decarboxylation. This modification increases the surface basicity and induces dissociative adsorption of the acid carboxylic group, facilitating the C-C bond cleavage by weakening the bond adjacent to the carboxyl group.

Summary: CuO-based nanostructures have been extensively studied in recent years in the fields of catalysis, sensing, and energy conversion and storage. The properties of these nanostructures are closely related to the morphology and crystallinity of CuO. However, the controlled deposition of CuO thin films by atomic layer deposition (ALD) has been challenging due to limited understanding of nucleation behavior and growth process. In this study, a novel ALD process using copper(II) trifluoroacetylacetonate [Cu(tfacac)(2)] as the metal precursor was developed. The nucleation and initial growth of CuO film were found to be dependent on the surface OH concentration. The research provides a strategy for tailoring the structure and properties of thin films via ALD, which has promising applications in designing well-tailored nanostructures.
