Summary: This study focused on the synthesis and characterization of propylsulfonic acid-functionalized nanocomposites based on natural rubber and hexagonal mesoporous silica (NRHMS-SO3H) as heterogeneous acid catalysts. The catalytic performance of these nanocomposites was evaluated in the esterification of levulinic acid with alcohols. Compared to traditional hexagonal mesoporous silica, the NRHMS-SO3H nanocomposites exhibited higher catalytic activity due to the synergistic effect between the strongly acidic-functional group and surface hydrophobicity. Tuning the hydrophobicity and acidity on a nanocomposite surface proved to be an effective strategy for energy reduction in catalysis.

Summary: Recent research on tandem catalysis has focused on designing biosynthetic pathways using enzymes and inorganic catalysts in single-pot systems. By cleverly utilizing porous supports, incompatible enzymes and inorganic catalysts can be successfully integrated to enhance the properties of combined catalysts. Studies have shown that supports can stabilize catalysts and act as active components within the systems. Ongoing research is exploring successful combinations of enzymes and inorganic catalysts supported on porous supports for tandem reactions along with the challenges that still need to be addressed.

Summary: A quaternized polybenzimidazole (PBI) membrane was synthesized by grafting a dimethylimidazolium end-capped side chain onto PBI. The hybrid membrane exhibited lower swelling ratio, higher mechanical strength, and better oxidative stability compared to the pristine membrane, but the morphology conducive to ion transport was only successfully developed in the pristine membrane. Both membranes showed good alkaline stability at 80 degrees C and demonstrated promising power densities at 60 degrees C for fuel cell applications.

Summary: This study presents a novel hybrid inorganic-organic architecture called polyionic nanoclays (PINCs), which are composed of two-dimensional, few nanometer-thick magnesium phyllo(organo)silicate nanosheets with ordered imidazolium functionalities. The PINCs demonstrate high ionic density, exchangeability of counteranions, and the ability to tailor the organic component, showing promising potential in catalysis, ion exchange, energy storage, and other applications. Additionally, the study also reveals the remarkable catalytic activity of gold nanoparticles supported on PINCs, suggesting a major synergistic effect compared to similar nanoparticles suspended in water.

Summary: Polyoxometalates (POMs) are polyatomic anions composed of transition metal oxyanions connected by shared oxygen atoms. They can function as electron relays and their properties can be enhanced through functionalization with amino organic compounds. Recent advancements in the synthesis of organoimido derivatives of POMs have paved the way for the development of unique nanostructured organic-inorganic hybrid molecular materials.

Summary: Crystalline materials have been crucial for the development of hybrid organic-inorganic perovskites (HOIPs), leading to interesting applications like solar cells and optoelectronic devices. Recently, the glassy state of HOIPs, which retains the basic building blocks of crystalline HOIPs but lacks long-range periodic order, has been discovered. The emerging family of glasses formed from HOIPs exhibit diverse properties complementary to their crystalline state. This mini review highlights the chemical diversity of 3D and 2D crystalline HOIPs and showcases the production of glasses from these materials, with a focus on achievements in melt-quenched glasses. Our perspective on the future of this new family of materials is also provided.

Summary: Non-phosphorous rhodium-containing catalysts were designed and synthesized for the direct conversion of olefins to alcohols via tandem hydroformylation/hydrogenation. The catalytic performance showed high activity, chemoselectivity, and stable hydroformylation yield in at least the first 5 cycles, although there was a decrease in alcohol selectivity. The influence of temperature, reaction time, total pressure, and molar CO/H2 ratio of syngas on oxygenate yields was discussed in the study.

Summary: Organic-inorganic hybrid silica films with circularly polarized luminescence (CPL) properties were prepared by in-situ polycondensation of a cholesteric liquid-crystalline organosilane, chiral dopant, and aggregation-induced emission (AIE)-active tetraphenylethene (TPE) derivative under acidic conditions. The resulting films exhibited bright CPL with absolute g(lum) values of approximately 0.15, predominantly attributed to the long-range ordered supramolecular helical structure. The handedness of the CPL was determined by the selective reflection of the cholesteric liquid crystal films.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
