synthesis of high-quantum-efficiency and stable bromide-based blue-emitting perovskite nanoplatelets.

We present a facile synthetic approach for the growth of two-dimensional CsPbBr nanoplatelets (NPLs) in the temperature range of 50-80 °C the vacuum-assisted low-temperature (VALT) method. In this method, we utilized the solubility of the PbBr precursor at temperatures high than the reaction temperature, thus making Br available during the reaction to form NPLs with fewer defects. The high chemical availability of Br during the reaction changes the growth dynamics and formation of highly crystalline nanoplatelets.

Temperature-Dependent Superhydrophobic Functionalized Coordination Polymers (SFCPs) for Selective Adsorption of CH over CH.

We prepared two new superhydrophobic functionalized coordination polymers (SFCPs) [Zn(OH)(BTMB)(4,4'-Bipy)] ⊃ solvent, , and [Cd(OH)(BTMB)(4,4'-Bipy)] ⊃ solvent, , by solvothermal methods. For , the single-crystal XRD structure revealed that it contains two crystallographically distinct ions with two different types of coordination geometries of and , exhibiting a unique superhydrophobic behavior with microporosity. Compound exhibits superhydrophobicity with a contact angle of 155.

Functionalized nona-silicide [SiR] Zintl clusters: a new class of superhalogens.

Superatoms, due to their various applications in redox and materials chemistry, have been a major topic of study in cluster science. Superhalogens constitute a special class of superatoms that mimic the chemistry of halogens and serve as building blocks of novel materials such as super and hyper salts, perovskite-based solar cells, solid-state electrolytes, and ferroelectric materials. These applications have led to a constant search for new class of superhalogens.

Unraveling the origin of interactions of hydroxychloroquine with the receptor-binding domain of SARS-CoV-2 in aqueous medium.

Interactions of hydroxychloroquin (HCQ) with the receptor binding domain (RBD) of SARS-CoV-2 were studied from atomistic simulation and ONIOM techniques. The key-residues of RBD responsible for the human transmission are recognized to be blocked in a heterogeneous manner with the favorable formation of key-residue:HCQ (1:1) complex. Such heterogeneity in binding was identified to be governed by the differential life-time of the hydrogen bonded water network anchoring HCQ and the key-residues.

Theoretical analysis of bacterial efflux pumps inhibitors: Strategies in-search of competent molecules and develop next.

Multi-drug resistance (MDR) bacteria pose a significant threat to our ability to effectively treat infections due to the development of several antibiotic resistant mechanisms. A major component in the development of the MDR phenotype in MDR bacteria is over expression of different-type of efflux pumps, which actively pump out antibacterial agents and biocides from the periplasm to the outside of the cell. Consequently, bacterial efflux pumps are an important target for developing novel antibacterial treatments.
