Summary: The non-covalent modification of CNTs and xGnP with ILs had a significant impact on the PU matrix. The electrical conductivity and EMI SE of the composites were influenced by the loading, dispersion of the fillers, and the nature of IL. Composites with IL105 showed higher electrical conductivity and EMI SE due to better interaction with the PU matrix compared to composites with IL101.

Summary: Thermogalvanic cells can convert waste heat energy into electrical energy, while thermocapacitors can store this electrical energy. This study investigates the use of nanostructuring to enhance the thermocapacitance performance of polyacrylate hydrogel containing [Fe(CN)(6)](3-/4-). The results show that modifying the electrode with nanomaterials increases the electroactive surface area and charging-discharging rates, while changing the degree of neutralization of the hydrogel significantly improves thermocapacitance when high concentrations of ferricyanide/ferrocyanide electrolyte are available.

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.
