Summary: The adsorption of polymers on the surface of mesoporous silica nanoparticles allows for versatile adhesion between hydrogels or biological tissues. However, when the number of nanoparticles deposited exceeds a critical threshold, thick multilayers form at the interface and decrease the adhesion strength. To overcome this limitation, spherical aggregates were prepared by spray drying, resulting in stronger cohesion between nanoparticles. The adhesion energy with these supraballs was significantly enhanced compared to nanoparticles, and corrugated interfaces stabilized by supraballs contributed to the largest adhesion enhancement.

Summary: A bifunctional core-shell catalyst consisting of Ni nanoparticles encapsulated by an Al-doped mesoporous silica shell was reported, which achieved 100% conversion of vanillin and >99% yield of 2-methoxy-4-methylphenol. The catalytic activity remained stable after 10 recycles due to the unique mesoporous core-shell structure. Incorporating Al atoms into the silica shell significantly increased the number of acidic sites. This work provides an efficient bifunctional hydrodeoxygenation catalyst and a new synthetic protocol for designing non-noble metal catalysts.

Summary: Silica nanoparticles (SNPs) have versatile synthetic methods and tunable physicochemical properties, making them promising for biomedical applications. In this study, hollow mesoporous SNPs (HMSNPs) with different layer compositions were fabricated, and their degradation profiles were characterized in simulated body fluid. The results showed that the composition and number of layers influenced degradation rates, with particles containing more disulfide bridges being more responsive to enzymatic degradation. These findings suggest the potential utility of layer-by-layer HMSNPs for controlled drug delivery.

Summary: This study synthesized Spherical Mesoporous Silica Particles (SMSP) with particles size ranging from 0.15 to 0.80 μm and average pore diameter of 2.4 nm as carriers for the basic amino acid L-arginine. Impregnation with acidic solution did not modify the carrier, while impregnation with basic solution led to carrier degradation, affecting its porosity. These findings suggest pH of the impregnating solution plays a significant role in the degradation of SMSP during amino acid loading processes.

Summary: Compared to other hydrogen production methods, biohydrogen produced from biological origin like microalgae is significantly less harmful to the surrounding ecosystem and can replace conventional fossil fuels without emitting greenhouse gases. Substrates like food, agricultural waste, and industrial waste can be easily utilized after pretreatment, increasing hydrogen yield. Improving biofuel production at each stage can have a significant impact, making it a potentially useful tool. Thus, this study comprehensively covers various approaches to pretreat algal biomass, enzymes and catalysts for hydrogen production, variables influencing hydrogen production, and the potential applications of genetic engineering.

Summary: The impact of carbon dioxide on global warming is a pressing issue that requires immediate attention for the sake of the Earth's ecosystem and humanity. Diminishing atmospheric CO2 concentration through conversion is an attractive solution, which can also lead to the formation of valuable compounds. The use of thermal hydrogenation as a method to achieve this goal requires a catalyst due to the high stability of the CO2 molecule. The designed materials should exhibit outstanding performance and stability, with high selectivity for CO and CH4.

Summary: The demand for green and economically viable processes has boosted the research and development of Ordered Mesoporous Silicas (OMSs) using low-cost starting reagents. However, high production costs and environmental contamination remain as obstacles to the production of high quality OMSs. Waste utilization can help reduce costs and environmental impacts by reusing materials that have no other applications.

Summary: The aim of this study was to extract and characterize silica materials from various agro-industrial wastes including sugarcane bagasse, corn stalk, and rice husk. The results showed that silica yields of 17.91%, 9.39%, and 3.25% were obtained for RH, CS, and SCB, respectively. The textural properties indicated that the siliceous materials had mesoporous structures, with SCB and CS forming crystalline SiO2 and RH forming amorphous. XPS spectra demonstrated the presence of Si4+ species in RH, and Si3+/Si4+ tetrahedra in SCB and CS.

Summary: In this study, a simple, green, and environmentally friendly strategy using biochar loaded with self-emulsifying orange peel essential oil (BC/SE-OPEO) was proposed to efficiently adsorb and degrade the aromatic amine p-phenylenediamine (PPD). The results showed that the PPD removal efficiency of 50 mg BC/SE-OPEO reached 98% after 110 min at 40 °C. Mechanistic investigations revealed that reactive oxygen species (ROS) played a vital role in the degradation of PPD, which was eventually degraded to carbon dioxide and water.
