Article Abstract
The title compound, CHNO·Br·CBr, consists of one 4-formyl-,-di-methyl-benzenaminium bromide and a tetra-bromo-methane mol-ecule. In the crystal, the bromide ions link 4-formyl-,-di-methyl-benzenaminium moieties through inter-molecular C-H⋯Br and N-H⋯Br hydrogen bonds, while inter-molecular C-H⋯O hydrogen bonds link 4-formyl-,-di-methyl-benzenaminium cations, enclosing (18) ring motifs, into a di-periodic network structure. The tetra-bromo-methane mol-ecules fill the spaces between the layers. Neither π-π nor C-H⋯π(ring) inter-actions are observed. A Hirshfeld surface analysis of the crystal structure indicates that the most abundant contacts contributing to the crystal packing are from H⋯Br/Br⋯H (56.0%), Br⋯Br (12.1%), H⋯O/O⋯H (9.7%) and H⋯H (9.5%) inter-actions.

Although improving the charging cutoff voltage is an effective strategy to increase its capacity, LiCoO ("LCO") undergoes rapid capacity decay due to severe structural and interface degradations at high voltages. Herein, we proposed a multifunctional surface modification by coating nano-sized entropy materials (Li-La-Ti-Zr-Co-O, Nano-MEO). Nano-MEO rivets were constructed on the surface of LCO, which stabilized the fragile surface.

Carbapenemases, β-lactamases hydrolysing carbapenem antibiotics, challenge the treatment of multi-drug resistant bacteria. The OXA-48 carbapenemase is widely disseminated in , necessitating new treatments for producer strains. Diazabicyclooctane (DBO) inhibitors, including avibactam and nacubactam, act on a wide range of enzymes to overcome β-lactamase-mediated resistance.

Frozen storage deteriorates the texture and digestibility of frozen rice dough by damaging gliadin structure and starch integrity. This study investigated carboxymethyl chitosan (CMCh) and sodium carboxymethyl cellulose (CMCNa) as cry-oprotectants to mitigate these effects. Comprehensive analysis utilizing nuclear magnetic resonance (NMR), texture profile analysis (TPA), dynamic contact angle measurement (DCAT21), reversed-phase high-performance liquid chromatography (RP-HPLC), and circular dichroism (CD) demonstrated that 1.

Coordination polymers (CPs) are versatile materials formed by metal ions and organic ligands, offering a broad range of structural and functional possibilities. Phosphonates and phosphinates are particularly attractive ligands for CPs due to their multiple binding sites, varied coordination geometries, and ability to form robust network structures. Phosphonates, considered harder ligands, form strong bonds with hard metals such as Fe, while phosphinates offer additional versatility due to the varied pendant groups on phosphorus.

The effects of pressure on the crystal structure of scheelite-type perrhenates were studied using synchrotron powder X-ray diffraction and density-functional theory. At ambient conditions, the studied materials AgReO, KReO, and RbReO, exhibit a tetragonal scheelite-type crystal structure described by space group 4/. Under compression, a transition from scheelite-to-M'-fergusonite (space group 2/) was observed at 1.
