Summary: We synthesized and characterized a series of conducting polymer composites based on PEDOT:PSS:PVS with adjustable PSS/PVS ratio. These composites showed similar UV-vis absorption characteristics to highly doped PEDOT chains in a binary PEDOT:PSS composite, with high electrical conductivity and smooth surface morphology. Electrochemical transistors based on these composites exhibited good current modulation, and the PSS/PVS ratio was found to be an important factor governing the effectiveness of electrochemical doping and dedoping.

Summary: Alpha-heteroatom functionalization is a crucial strategy for C-C bond formation in organic synthesis, achieved by adding a nucleophile to electrophilic functional groups, such as iminium ions, oxocarbenium ions, and their sulfur analogues - sulfenium ions. In this study, a photoredox-enabled radical Pummerer-type reaction was proposed, which involved the single-electron oxidation of a sulfide followed by alpha-deprotonation to form alpha-thioradicals. These radicals then participated in radical-radical coupling reactions with azolium-bound ketyl radicals, leading to functionalized additive Pummerer products and providing a new synthetic approach for highly functionalized sulfurous products.

Summary: Selective electrochemical reduction of oxygen (O-2) via 3e(-) pathway to produce hydroxyl radicals (HO) is a promising alternative to conventional electro-Fenton processes. A nitrogen-doped CNT-encapsulated Ni nanoparticle electrocatalyst (Ni@N-CNT) was developed, which exhibited high selectivity towards O-2 reduction and generation of HO•via 3e(-) pathway. The exposed graphitized N on the CNT shell and Ni nanoparticles encapsulated within the tip of the N-CNT played crucial roles in the generation of *HOOH through a 2e(-) oxygen reduction reaction. The encapsulated Ni nanoparticles at the tip of the N-CNT also facilitated the direct decomposition of electrogenerated *H2O2, leading to sequential generation of HO• through a 1e(-) reduction reaction on the N-CNT shell without inducing Fenton reaction. Improved bisphenol A (BPA) degradation efficiency was observed compared to conventional batch systems (97.5% vs 66.4%). Trials using Ni@N-CNT in a flow-through configuration demonstrated complete removal of BPA within 30 minutes (k = 0.12 min(-1)) with a limited energy consumption of 0.068 kW.h.g(-1) TOC.

Summary: This study utilized biochar produced from dehydrated excess sludge to catalytically ozonate pollutants from landfill leachate. The biochar contained necessary catalytic sites originating from inorganic metals and organic matters in the sludge. These sites promoted the generation of reactive oxygen species and the removal rates of pollutants were enhanced by the synergistic interaction between microorganisms. The study provides insight into the mechanism of catalytic ozonation and offers a new approach for practical landfill leachate treatment.

Summary: In this study, graphene-based nanofluids were synthesized and their viscosities were determined. The molecular interactions of graphene nanoparticles were theoretically analyzed to understand the mechanisms affecting the viscosity of nanofluids. An analytical function describing the dependence of the relative viscosity on the concentration of graphene nanoparticles was obtained based on experimental results. It was found that the viscosity of the nanofluid was influenced by the structure of the graphene sheets, and the self-assembly of the nanoparticles played a crucial role in the viscosity changes.

Summary: This study synthesizes a variety of perovskite-type titanates (MTiO3, M = Zn, and Mn) and loads them onto functionalized magnetic graphene oxide (EDFG) to produce MTiO3 @EDFG nanocomposites. The materials were fully characterized, and the MTiO3 @EDFG nanocomposites were found to exhibit enhanced photocatalytic activity for the degradation of Rhodamine B under visible light irradiation. The enhanced activity was attributed to the inhibition of nanoparticle aggregation, improved electron transfer, increased surface area, and extended absorption range.

Summary: Molecular modelling and simulation were used to investigate the removal of amoxicillin (AMX) from water using iron nanoparticles (Fe3O4-NPs). The optimal conditions for adsorption were determined. The results showed that AMX molecules have high chemical potential and electrophilicity index, making them reactive. The adsorption of AMX onto Fe3O4-NPs was highly efficient under optimal conditions of pH 3, dosage of 0.5 g/L, AMX concentration of 60 mg/L, and a contact time of 60 min. Langmuir isotherm and pseudo-second-order kinetics provided the best fit to the adsorption data.

Summary: Laboratory illumination is strong enough to create a photostationary state (PSS) of amphiphilic azo-benzene compounds in water. The [cis]PSS/[trans]PSS ratios were observed to be 0.33-1.2 in D2O and 0.37-3.8 in dimethyl sulfoxide-d6. ortho-Fluoroazobenzene amphiphiles show higher cis-isomer concentration at equilibrium compared to non-fluorinated compounds due to differences in optical absorption profiles. The kinetics of isomerization were measured using UV-Vis spectroscopy and the ratio of trans-to-cis rates does not directly correlate with the observed PSS. The half-life for PSS formation is 40 minutes for fluorinated compounds and 80 minutes for non-fluorinated compounds.

Summary: This study designed an integrated structure of Cu2O@Au/Cu2O heterostructure particles, which achieved significantly enhanced photocatalytic performance by simultaneously considering the integrated structural characteristics and localized surface plasmon resonance (LSPR) effect. Experimental characterization and theoretical simulation confirmed the three-in-one synergy of the integrated heterostructure, including the LSPR effect of Au nanoparticles, the light scattering based on core-shell heterostructure, and the effective charge separation based on inter-embedded heterostructure. The concept of integrated heterostructure cooperated with LSPR effect provides a new strategy for designing future catalysts.

Summary: In this study, the recombination of separated ion-radical states (SIRS) in PAPh films was analyzed, and it was found that the contribution of X-SIRS recombination to total luminescence varies with different environments. It was also shown that the recombination of labile SIRS is independent of the nature of the atmosphere. The study theoretically substantiated that SIRS recombination can occur via the transfer of both positive and negative charges, and the efficiency of thermal activation of recombination processes depends on the ratio of radiant and conductive channels of energy transfer.

Summary: Bifunctional hybrids containing photochromic indolyl(thienyl) diarylethenes and an ionochromic rhodamine moiety connected by a dimethylene spacer were synthesized. These hybrids exhibit absorption at 450-455 nm and fluorescence at 560 nm in toluene. UV light triggers ring-closed non-fluorescent diarylethene formation, which can be reversed under visible light or in the dark. In the presence of H+ cation, a naked eye effect is observed with the opening of the rhodamine-spirolactam ring and a pink-crimson coloration at 561 nm accompanied by intense long-wavelength emission at 586 nm. This process is reversible by exposure to triethylamine, as confirmed by NMR experiments. The light-induced isomerizations and proton-induced transformations were explained using computational methods. Reversible switching of fluorescent properties can be achieved by light irradiation and proton.
