Summary: Recently, Riceberry rice has gained attention in Thailand due to its high nutritional value. In this study, silica was successfully extracted from Riceberry rice husk through hydrothermal synthesis for the synthesis of zeolite X. Hierarchical zeolite was prepared through acid modification and recrystallization. The extracted silica had high purity, and the acid-modified 0.5HCl-X showed a high surface area and monodisperse pore size distribution. The synthesized materials were used as adsorbents for propionic acid, and the adsorption capacity of 0.5HCl-X reached a maximum of 516 mg g(-1) at an equilibrium time of 30 minutes, following a pseudo-second order kinetic model.

Summary: Eco-friendly, low-cost, and highly efficient noble metal-free rice husk biomass-derived biochar was developed as a cocatalyst to improve the performance of zinc indium sulfide for photocatalytic H2 production. The optimized nanocomposite exhibited superior H2 production compared to pristine zinc indium sulfide under simulated light irradiation. The enhanced activity was attributed to efficient interfacial contacts between the materials, high surface area and conductivity of biochar, and ultrathin-layered structure of the nanosheets.

Summary: In this study, a low-cost catalyst and heterogeneous hydrogen producer were used for the upgrading of bio-crude. The synthesized Y zeolite showed better performance due to the introduction of TMAOH template. The upgraded oil yield increased and the coke amount reduced, leading to a higher heating value. Hydrogenation products were produced in higher amounts, consuming furan derivatives and lignin-derived compounds. Additionally, a one-pot catalytic hydrothermal treatment method was conducted, combining the bio-crude production and upgrading steps together.

Summary: Coupling graphene-based materials with SiC nanostructures is an effective strategy for improving photocatalytic CO2 reduction performance. In this study, vertical graphene (VG) sheets were synthesized on SiC nanowires derived from rice husks to form the VG@SiC/C composite. The resulting composite exhibited enhanced photocatalytic CO2 reduction, yielding CO and CH4 with yields of 25.5 and 2.3 μmol g-1 h-1, respectively, which is the highest CO yield among SiC-based photocatalysts. Defective VG sheets promoted sunlight absorption, CO2 adsorption and activation, electron-hole pair separation, and overall photocatalyst activity, leading to high CO2 reduction yield and selectivity.

Summary: Hyperosmotic tears can stimulate the cornea and cause dry eye symptoms, but the use of soft contact lenses can protect the cornea from these effects. Current measurement methods for tear osmolarity during lens wear do not accurately reflect the osmolarity of the tear film that covers the cornea. Dry eye patients can benefit from contact lenses with low salt diffusivity to reduce their tear osmolarity to normal levels.

Summary: Density functional theory (DFT)-based numerical calculations were conducted to study the relaxed and optimized structures of MoS2 and WS2 bilayers, followed by the adsorption of F and Cl. Electronic properties were examined through density of states (DOS) and band-structure calculations. Energy decomposition analysis (EDA) revealed that F weakens van der Waals interactions more in MoS2, while the opposite happens in WS2. Additionally, electrostatic interactions play a dominant role in these systems rather than dispersive van der Waals.

Summary: The purpose of this study was to determine if there are differences in evaporation flux between symptomatic and asymptomatic soft-contact-lens wearers, to assess the repeatability of a flow evaporimeter, and to measure the relationship between evaporation flux and tear properties and environmental conditions. The results showed that thicker lipid layer was associated with slower evaporation flux, higher evaporation flux was associated with faster tear breakup and ocular-surface temperature decline rate. Symptomatic lens wearers had higher evaporation flux, but the results were not statistically significant.

The nature of the support was found to have a significant influence on the catalyst's activity and selectivity, with the crystalline structure of ZrO2 having the greatest impact. Pure ZrO2 showed the highest methanol selectivity and CO2 conversion at high Zr:Ce ratios. In equimolar and Ce-rich conditions, basic sites and oxygen vacancies were found to be the key parameters affecting methanol production.

This study developed Zn-BTC MOF and its composites with CaIn2S4, achieving highly efficient and robust photocatalytic CO2 reduction to CH3OH under ambient conditions, using H2O2 as the hydrogen source. Among the composites, ZMCIS4 demonstrated excellent performance with a CH3OH evolution of 49100 μmol/g.cat and a quantum efficiency of approximately 78.41%. The enhanced performance was attributed to the production of nascent hydrogen atoms (H center dot) through the photo-splitting of H2O2 on the ZMCIS surface.

Among them, an amorphous silica-alumina catalyst (SAL-3) modified with Ag showed the highest improvement in catalytic activity and stability when operated in H2 flow. The generation of reversible acid sites was found to be the reason behind the enhanced activity and stability of this Ag/SAL-3 catalyst. The effects of various parameters on the catalytic activity of Ag/SAL-3, such as reaction temperature, contact time, Ag content, and carrier gas, were investigated.
