Summary: This study presents a Co2O3/CuO heterostructure as an efficient OER electrocatalyst and photocatalyst synthesized through a simple hydrothermal method. The fabricated electrode material exhibits a higher BET surface area of 112 m2 g-1 due to the presence of nanoparticles on the rods nanocomposite. Various electrochemical tests, including CV, LSV, EIS, chronoamperometry, and ECSA, confirm the excellent performance of the electrode material with an overpotential of 272 mV and a low Tafel value of 40 mV dec-1. Moreover, the material shows remarkable photodegradation efficiency of 98% for methylene blue dye and maintains stability for up to 5 cycles. The enhanced OER and degradation efficiency can be attributed to the increased active sites, larger surface area, and superior charge transport properties of Co2O3/CuO.

Summary: In this study, a composite film (CMC-PSIS) was prepared by dispersing carboxymethyl cellulose (CMC) in a polystyrene block polyisoprene block polystyrene polymer (PSIS) using a simple casting technique. Cu and Ni ions were adsorbed onto CMC-PSIS and then converted into Cu-0 and Ni-0 nanoparticles (NPs) in the presence of NaBH4. The prepared catalysts were characterized and used for the reduction/degradation of four model pollutants. The results showed that CMC-PSIS/Cu exhibited the highest rate constant for the degradation of methyl orange, while Cu NPs showed the shortest reaction time. CMC-PSIS/Ni achieved the highest degradation extent for rhodamine B among all the dyes.

Summary: This study presents a facile fabrication strategy for a three-dimensional reduced graphene oxide hydrogel embedded with lignin nanoparticles (LNP), which exhibits promising potential for environmental applications. The LNP were synthesized from walnut shell waste via a direct chemical method and were integrated into the continuous porous network of rGO to create the rGO@LNP hydrogel. Various analytical techniques were employed to characterize the structure and properties of the hydrogel. The efficiency of the hydrogel as an adsorptive platform was evaluated using methylene blue and Pb2+ as model pollutants, and its antibacterial activities were also tested. The results demonstrated that the inclusion of LNP significantly enhanced the pollutant's uptake ability of the hydrogel and exhibited improved bactericidal effect compared to bare LNP and rGO. This innovative approach utilizing the synergy of functional properties of LNP and rGO has great potential for water filtration and remediation.

Summary: This research introduces a catalytic system consisting of highly dispersed Cu nanoparticles encapsulated in a nanoporous carbon structure for selective hydrogenation. The Cu@C catalysts demonstrate high activity in the hydrogenation of y-valerolactone (GVL) to 1,4-pentanediol. The dispersion of the active copper phase, along with particle size and surface acidity, directly affects the catalytic performance. Overall, Cu@C shows promise as a non-noble metal-based catalytic system for upgrading biomass-based platform molecules through selective hydrogenation.

Summary: In this study, the binding of DNA with double alkyl chain metallosurfactants in ionic liquid media was investigated using various spectral techniques. The size and shape of the ligand, as well as the hydrophobicity of the complexes, were found to significantly affect the binding affinity of the complexes to DNA. The presence of an ionic liquid additive enhanced the binding strength of the surfactant-cobalt(III) complex to DNA, with the double alkyl chain complex exhibiting stronger binding due to its increased hydrophobicity. The long aliphatic chain amine ligand in the metallosurfactant-oxime complex played a definite role in the binding through its hydrophobicity. The results also showed that the extent of DNA binding was greater for the double alkyl chain complex.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.
