War and peace: exploring microbial defence systems as a source of new antimicrobial therapies.

The WHO has compiled a list of pathogens that urgently require new antibiotics in response to the rising reports of antibiotic resistance and a diminished supply of new antibiotics. At the top of this list is fluoroquinolone-resistant , fluoroquinolone-resistant spp. and vancomycin-resistant .

Formation Dynamics of Thermally Stable 1D/3D Perovskite Interfaces for High-Performance Photovoltaics.

Direct understanding of the formation and crystallization of low-dimensional (LD) perovskites with varying dimensionalities employing the same bulky cations can offer insights into LD perovskites and their heterostructures with 3D perovskites. In this study, the secondary amine cation of N-methyl-1-(naphthalen-1-yl)methylammonium (M-NMA) and the formation dynamics of its corresponding LD perovskite are investigated. The intermolecular π-π stacking of M-NMA and their connection with inorganic PbI octahedrons within the product structures control the formation of LD perovskite.

Tuning the selectivity of NH oxidation via cooperative electronic interactions between platinum and copper sites.

Selective catalytic oxidation (SCO) of NH to N is one of the most effective methods used to eliminate NH emissions. However, achieving high conversion over a wide operating temperature range while avoiding over-oxidation to NO remains a significant challenge. Here, we report a bi-metallic surficial catalyst (PtCuO/AlO) with improved Pt atom efficiency that overcomes the limitations of current catalysts.

Carboxyl-Functionalized Alkylimidazolium Salts for Thermomorphic Acid-Catalyzed Polysaccharide Hydrolysis in Water.

We report the use of carboxyl-functionalised alkylimidazolium salts as thermomorphic acid catalysts for the hydrolysis of cellulose and starch in water, free from organic solvents and auxiliary substances. The imidazolium salts are insoluble in water at room temperature and dissolve to form homogeneous solutions upon heating. Following catalysis at elevated temperatures the solution is cooled and the imidazolium salt precipitates from the aqueous layer to afford an aqueous glucose solution.

Tandem Deacetalization-Knoevenagel Condensation Reactions for the Synthesis of Benzylidene Malononitrile Using Ruthenium(II) Cymene Complexes.

In this study, we report the synthesis and full characterization of five novel ruthenium(II) cymene complexes with the general formula [Ru(cym)(L')Cl], featuring N,O- and N,N-coordinating pyrazolone-based hydrazone ligands. We have characterized these complexes using single X-ray crystallography, Fourier-transform infrared spectroscopy (FT-IR), Nuclear magnetic resonance (NMR), elemental analysis, and Electrospray Ionization Mass Spectroscopy (ESI-MS). Crystallographic analysis confirmed that all of the complexes have a similar type of half-sandwich, pseudo-octahedral "three-legged piano-stool" geometry where the cymene moiety displays the typical η-coordination mode and the hydrazone ligands coordinate to the Ru(II) center in a bidentate fashion.
