This study broadens the family of 2D layered perovskites by demonstrating that it is possible to self-assemble organic charge-transfer complexes in their organic layer. Organic charge-transfer complexes, formed by combining charge-donating and charge-accepting molecules, are a diverse class of materials that can possess exceptional optical and electronic properties.

Polymer-derived ceramics are a versatile class of multifunctional materials synthesized the high-temperature treatment of a preceramic polymer. In this work, we report the synthesis of a vanadium carbide-embedded carbonaceous hybrid by pyrolyzing a modified preceramic polymer incorporating vanadium acetylacetonate in a polysilsesquioxane followed by hydrofluoric acid etching. The structural and microscopic characterisation confirmed the uniform distribution of nanoparticulate vanadium carbide in the matrix.

The construction of strong metal-support interactions (SMSI) is an effective strategy to enhance and control heterogeneous catalysts. However, conventional methods require pre-synthesized metal-loaded catalysts, followed by SMSI formation via high-temperature treatment under oxidative/reductive atmospheres, adsorbate-mediated treatment, and photo-treatment, adding complexity to catalyst synthesis and hindering continuous interfacial tuning. In this work, a "photobreeding" method is employed to treat ZnCdS, leveraging the UV-induced photochromic reaction of ZnS to generate metallic Zn at room temperature, while CdS remains inert.

The most significant challenge facing magnesium alloy stents is their ability to withstand complex deformation during their application. To gain a deeper understanding of the impact of stent deformation on the protective capabilities of the coating, this paper presents an amplified stent deformation model. The models were coated with either a low elongation material-Poly(D, L-lactide) (PDLLA) or a high elongation material-Poly(butylene adipate-co-terephthalate) (PBAT), followed by the application of a rapamycin-loaded PLGA as drug-eluting layer.

In this work, carbon nanodots (CNDs) were synthesized via a pyrolysis carbonization method using petals. The synthesized CNDs exhibit optical absorption in the UV region, with a tail extending out into the visible range. When these CNDs interact with Ho ions through charge transfer processes, they form an RE-CNDs hybrid (Rare Earth-CNDs hybrid), resulting in fluorescence quenching in an aqueous solution.

The coordination chemistry of the planar, doubly π-extended bipyridine analog, 6,6',7,7'-biphenanthridine (p-biphe), is presented. The phenanthridine units in p-biphe are fused together at the 6- and 7- positions, and the resulting rigid ligand is compared with the more flexible parent "biphe" fused only at the 6-positions. p-Biphe is intensely fluorescent in solution with a much higher quantum yield, but, unlike biphe, at 77 K the fluorescence is not accompanied by any significant phosphorescence.
