Chemical oxidation of a double-twisted nanographene led to quantitative generation of corresponding dicationic species, which exhibited an intense absorption band tailing to 1500 nm wherein two orthogonally arranged π-skeletons contributed to transitions and a high dissymmetry factor of -0.0209 was recorded at 1443 nm in the NIR-II region.

The construction of thin film heterostructures has been a widely successful archetype for fabricating materials with emergent physical properties. This strategy is of particular importance for the design of multilayer magnetic architectures in which direct interfacial spin-spin interactions between magnetic phases in dissimilar layers lead to emergent and controllable magnetic behavior. However, crystallographic incommensurability and atomic-scale interfacial disorder can severely limit the types of materials amenable to this strategy, as well as the performance of these systems.

Terdizolamide phosphate (TZD), a second-generation oxazolidinone antibiotic with a long half-cycle, poses a potential threat to ecosystems and humans if present in water over an extended duration. Magnetic biochar (CF-biochar) loaded with CeFeO was firstly synthesized by microwave ablation-anaerobic carbonization using corn straw as raw material and Ce(NO) and Fe(NO) as modifiers. These modifiers were used as activators for peroxymonosulfate (PMS) and adsorbents for removing TZD.

A cost-effective strategy is reported utilizing ionic liquid (IL), 1-hexyl-3-methylimidazolium bisulfate ([HMIM] HSO), to delaminate TiC MXene, thereby enhancing its efficiency in electrocatalyzing tryptophan (Trp) oxidation. The positively charged IL effectively intercalates within the negatively charged MXene layers, fostering structural stability through π-π stacking and electrostatic interactions. Consequently, the resulting IL-TiC composite not only maintained the inherent electronic conductivity of TiC but also significantly augmented its electrocatalytic prowess.

Natural products, particularly plants, remain a vital source of bioactive compounds owing to their unparalleled metabolic diversity across pharmaceuticals, cosmetics, foods, and agriculture. However, this diversity, encompassing not only a multitude of compounds but also their varying chemical and physical properties, presents a challenge in their effective utilization. Targeted analysis of specific metabolites, as well as untargeted approaches covering a wide metabolite range, necessitate optimal extraction solvents tailored to meet diverse requirements.

Intermolecular oxidative N-N bond formation reactions are quite challenging and are largely uncharted. N-N linked dimeric indolosesquiterpene alkaloids represent an underexplored class of natural products, and strategies for direct dehydrogenative N-N bond formation are limited. Here, we have reported that a late-stage visible-light photoredox catalysis facilitates N-N bond formation, leading to the total syntheses of atropo-diastereomers dixiamycins A () and B ().
