Summary: In this study, several chemically responsive bola-glycolipids and dimeric carbohydrate- and diarylethene-based photoswitchable derivatives were designed and synthesized. The dimeric glycolipids formed stable gels in various solvent systems. The best performing gelators in this series contained decanedioic and dithienylethene (DTE) spacers, which formed gels in eight and nine of the tested solvents, respectively.

Summary: The pH dependence of perylene bisimide gels is investigated, showing that both the final and starting pH can impact the resulting gel properties. Adjusting the starting pH from 9 to 6 results in different worm-like micelles and gels with different mechanical properties. This highlights the importance of controlling pH for gelation and opens up possibilities for different morphologies and properties.

Summary: In this study, we designed and synthesized a thermoresponsive organogelator for oil gelling from oil/water mixtures, which plays a significant role in oil spill remediation. The gelators formed porous fibrillar structures with high stiffness, and the three-dimensional networks were created by hydrogen bonding and van der Waals forces. Poly(styrene-co-10-undecenoic acid) has the advantages of a straightforward synthesis procedure, room-temperature conditions, and easy powder delivery, making it an attractive alternative to existing oil spill response methods.

Summary: The phase behavior of 12-hydroxystearic acid in even-numbered alkanes was studied. The solid phase was stabilized at low concentration and high temperature with increasing alkane length. Liquid-liquid immiscibility was observed in larger alkanes. The association of 12-hydroxystearic acid played a role in its phase behavior and gelation behavior. The importance of solute association in small molecule organogelators and its potential as a molecular design parameter were discussed.

Summary: This study presents a method combining microencapsulation in supramolecular gels and the use of profragrances to increase the persistence of fragrances in the air. The controlled lactonization of esters derived from o-coumaric acid was observed after exposure to solar light, releasing coumarin and alcohol. The reaction rate was found to be slower in the gel compared to the solution. A stronger and opaque gel prepared with 1% w/v gelator concentration was used for profragrances encapsulation, resulting in a significant reduction of lactonization reaction.

To improve the adsorption capability, composites were prepared by combining Mg-Al-LDH with low-cost Mangifera indica stone biomass (MISB). The results showed that the composites had high adsorption capacities for RG5 dye and could be regenerated.

Summary: Hydrophobic coatings inspired by the lotus effect have gained popularity for their ability to solve various problems. The sol-gel method, utilizing silica, alumina, and titania, is explored as an environmentally friendly approach to produce water-based hydrophobic coatings. This study focuses on producing water-based hydrophobic coatings for cotton and polyester fabrics using a one-step sol-gel method. The coated fabrics exhibited improved hydrophobic properties, altered surface morphologies, and lower air permeability compared to uncoated fabrics. TEOS-PDMS coating provides a promising approach for enhancing the hydrophobic and surface properties of cotton and polyester fabrics.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
