Summary: Selective partial oxidation of benzyl alcohol to benzaldehyde without additives was achieved using advantageous titanium oxide nano-photocatalysts. Titanate nanotubes and nanocores of anatase surrounded by amorphous titanium hydroxide phase performed the best. Different mechanisms and oxidation pathways are photo-catalyzed depending on the physicochemical features of the nanocatalysts and the light irradiation. The study also revealed that utilizing organic compounds like benzoquinone as scavenger may result in photolytic decomposition.

Summary: In this study, plasmonic Au nanoparticles were used to enhance the photocatalytic activity of BiVO4/BiOBr nanosheets through surface plasmonic resonance. The highest conversion of benzyl alcohol (100%) and the maximum yield of benzaldehyde (99%) were achieved using BiVO4/BiOBr/Au 3% after 4 hours of irradiation. Singlet oxygen was identified as the dominant species responsible for the photocatalytic oxidation of benzyl alcohol to benzaldehyde. The proposed mechanism involved the excitation of electrons in BiVO4/BiOBr/Au to singlet states, which eventually produced triplet excitons and reacted with dissolved O2 to generate singlet oxygen. The thermodynamic analysis indicated that the reaction was favorable.

Summary: Selective oxidation of benzyl alcohols to aldehydes and 2-naphthol to BINOL was achieved by activating molecular oxygen and hydrogen peroxide over an iron-oxide catalyst embedded in halloysite nanotube. The involvement of superoxide radical bound Fe-III species in the oxidation reaction was confirmed through ESR, Raman, and in situ FTIR spectroscopic analysis. The stability of such radical bound Fe-III species in halloysite nanotube was analyzed through DFT calculations, suggesting that end-on binding was more favorable than side-on binding.

Results indicate that the different effects of hybrid and symmetric omega-3 phospholipids on lipid bilayers' microscopic organization, with cholesterol able to suppress non-lamellar structures induced by symmetric polyunsaturated lipids. The structural organization of the resulting bilayer does not fit neatly into typical liquid ordered or liquid disordered phases, showing loose packing of lipid chain segments.

Summary: The existing literature survey reports on the effect of preparation methods of metal-based semiconductor photocatalysts on photocatalytic H-2 generation are rare and conflicting. In this study, we compared different copper/titania-based photocatalysts for H-2 generation prepared by photodeposition and impregnation methods. Our study aimed to establish a correlation between physicochemical/electronic properties and photocatalytic performances for H-2 generation through material characterization and kinetic modeling. The results showed that H-2 generation photoefficiency over impregnated CuxOy/TiO2 is related to an even distribution of Cu(0)/Cu(I) on TiO2 and extended charge carrier lifetime and separation.

Summary: LL-III is an anticancer peptide that can translocate across tumor cell membranes. However, the mechanism through which it enters the cell cytoplasm is still unknown. In this study, we used physico-chemical techniques to characterize the interaction of LL-III with liposomes resembling the lipid matrix of the tumor cell membrane. Our results show that the peptide selectively interacts with the model tumor cell membrane without disrupting the lipid bilayer, but alters its properties by promoting lipid reorganization and increasing membrane permeability.

Summary: To protect human and environmental health, researchers are focusing on discovering and developing new molecules with high biocompatibility and biodegradability. Surfactants are particularly urgent in this matter, and biosurfactants derived from microorganisms are a promising alternative. Rhamnolipids, a well-known family of biosurfactants, have been extensively studied for their production and physicochemical characterization, although a clear structure-function relationship is still lacking. This review aims to provide a comprehensive discussion of the physicochemical properties of rhamnolipids under different solution conditions and their structure, while also addressing unresolved issues for their potential replacement of conventional surfactants.

Summary: The search for new synthetic melanin-related pigments with antioxidant and photoprotective properties is important for dermo-cosmetic purposes. In this study, a melanin derived from 5,6-dihydroxyindole-2-carboxylic acid (DHICA) was synthesized and found to have similar structural properties to DHICA melanin. The synthesized pigment demonstrated stronger UV-visible absorption and improved solubility compared to DHICA melanin. Furthermore, the pigment exhibited marked antioxidant properties and enhanced inhibitory action against lipid peroxidation. These findings suggest that the melanin derived from DHICA has potential as a functional ingredient in dermo-cosmetic formulations.

Summary: Formates are promising salts for hydrogen storage, capable of catalytically converting to bicarbonate and being regenerated under moderate pressure. However, there are still challenges to be addressed, such as reaction kinetics, stability, cyclability, and increasing energetic density. This work critically reviews the current state and highlights theoretical limitations and applicative shortcomings, providing perspective on future research. Despite the existing bottlenecks, there is promising room for improvement, with state-of-the-art catalytic systems potentially reaching 72% energetic efficiency, which could be improved up to 90%.

Summary: Several studies have demonstrated that combining TiO2 and Cu2O enhances photocatalytic activity by creating a heterojunction that extends light absorption in the visible spectrum and reduces electron-hole recombination. Ball milling is an effective method for preparing photocatalysts, and the optimal conditions for synthesizing a Cu2O-TiO2 photocatalyst have been identified (1%wt. Cu2O in TiO2 prepared by ball-milling at 200 rpm and 1 min milling time). The photocatalytic hydrogen generation efficiency has been optimized by considering sacrificial species, temperature, and pH, achieving a light-to-chemical energy efficiency of 8%. Additionally, the system has shown potential for hydrogen production under direct solar light, with 60% attributed to visible light and 40% attributed to UV light.

Summary: The ability of Methylobacterium extorquens to grow on methanol as the sole carbon and energy source is influenced by the composition and function of the lipopolysaccharide (LPS) in the outer membrane. The LPS of M. extorquens is unique, with non-phosphorylated and heavily O-methylated core oligosaccharides, and a distinctive lipid A structure. These chemical features impact the resistance of the membrane to methanol, regulating membrane ordering and dynamics.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
