Nitrous oxide (NO) has been increasingly used for recreational purposes due to its dissociative and euphoric properties. Exposure to NO results in the deactivation of in vivo vitamin B, leading to subsequent neurological sequelae due to vitamin B deficiency.7 Current management focuses on cessation of exposure and replacement therapy, yet patients may continue to suffer from permanent neurological damage.

Background: Alcohol use disorder (AUD) is associated with deficits in social cognition and behavior, but why these deficits are acquired is unknown. We hypothesized that a reduced association between actions and outcomes for others, i.e.

Context: Inspired by the newly synthesized endohedral fullerene T CH@C (1) and based on extensive density functional theory calculations, we predict herein a series of endohedral borafullerenes C CH@BC (4), T BH@BC (5), C HO@BC (6), C NH@BC (7), and T C@BC (8) which possess a BC (3) shell isovalent with C, with the neutral D C@BC (9) obtained from C@BC (8) by symmetric C─B substitutions. Detailed adaptive natural density partitioning (AdNDP) bonding analyses and iso-chemical shielding surfaces (ICSSs) calculations indicate that these core-shell species are spherically aromatic in nature, rendering high stability to the systems. More interestingly, based on the calculated effective donor-acceptor interaction between LP(O) → LV(B@BC) in HO@BC (6), we propose the concept of boron bond (BB) in chemistry which is defined as the in-phase orbital overlap between an electronegative atom A as lone-pair (LP) donor and an electron-deficient boron atom with a lone vacant (LV) orbital as LP acceptor.

The development of high-performance electrocatalysts for hydrogen evolution reaction (HER) in different pH conditionsis pivotal in producing green hydrogen, but remains challenging. Herein, we regulate the p-d orbitals hybridization between B and Pt for effective and durable HER at all pH ranges by controlling the inserted B atom. Consequently, the optimized B-doped Pt catalysts with 20 at.

The development of all-solid-state frustrated Lewis pairs (FLPs) metal-free hydrogenation catalysts with excellent activity and stability remains a significant challenge. In this work, B, N codoped FLPs catalysts (De-rGO-NB) were prepared by the strategy of fabricating carbon defects and heteroatom doping on the surface of reduced graphene oxide and applied in the selective hydrogenation of α,β-unsaturated aldehydes to unsaturated alcohols. It was found that electron-rich pyridine-N (Lewis base) and adjacent electron-deficient B-N (Lewis acid) sites could be constructed on the surface of reduced graphene oxide using dicyandiamide and metaboric acid as N and B sources, thus forming FLPs sites.
