In this study, we investigated the influence of BiO and WO on both structure and optical properties of 50ZnO:(49 - x)BO:1BiO:xWO; x = 1, 5, 10 glasses doped with 0.5 mol% EuO. IR spectroscopy revealed the presence of trigonal BØ units connecting superstructural groups, [BØO] metaborate groups, tetrahedral BØ units in superstructural groupings (Ø = bridging oxygen atom), borate triangles with nonbridging oxygen atoms, [WO] tetrahedral, and octahedral WO species. Neutron diffraction experimental data were simulated by reverse Monte Carlo modeling. The atomic distances and coordination numbers were established, confirming the short-range order found by IR spectra. The synthesized glasses were characterized by red emission at 612 nm. All findings suggest that Eu doped zinc borate glasses containing both WO and BiO have the potential to serve as a substitute for red phosphor with high color purity.

The incorporation of non-benzenoid motifs in graphene nanostructures significantly impacts their properties, making them attractive for applications in carbon-based electronics. However, understanding how specific non-benzenoid structures influence their properties remains limited, and further investigations are needed to fully comprehend their implications. Here, we report an on-surface synthetic strategy toward fabricating non-benzenoid nanographenes containing different combinations of pentagonal and heptagonal rings.

Objective: To evaluate effect of inoculum size of extended-spectrum β-Lactamase (ESBL)-producing-, AmpC-producing-, and KPC-producing Escherichia coli and Klebsiella pneumoniae on the in vitro antibacterial effects of imipenem/relebactam (IMR) and ceftazidime/avibactam (CZA).
Methods: We compared the impact of inoculum size on IMR and CZA of sixteen clinical isolates and three standard isolates through antimicrobial susceptibility tests, time-kill assays and in vitro PK/PD studies.
Results: When inoculum size increased from 10 to 10 CFU/mL, an inoculum effect was observed for 26.

Article Synopsis
- * Researchers collected fecal samples from 775 hospitalized patients and 357 community members; they found high rates of fluoroquinolone-resistant (FQR), extended-spectrum cephalosporin-resistant (ESCR), and multidrug-resistant (MDR) GNB in both groups.
- * The study highlighted that antibiotic-resistant bacteria are common in both hospitals and communities, emphasizing the need for further investigation into how these resistant strains spread between these environments.

VhChiP is a chitooligosaccharide-specific porin identified in the outer membrane of Vibrio campbellii type strain American Type Culture Collection BAA 1116. VhChiP contains three identical subunits, and in each subunit, the 19-amino acid N-terminal segment serves as a molecular plug (the "N-plug") that controls the closed/open dynamics of the neighboring pores. In this study, the crystal structures of VhChiP lacking the N-plug were determined in the absence and presence of chitohexaose.

Lignin is a complex biopolymer comprising phenolic monomers with different degrees of methoxylation and may potentially enhance the degradation of soil pollutants such as polycyclic aromatic hydrocarbons (PAHs) through co-metabolism. However, the contribution of lignin constituents, including phenolic and methoxy subunits, to PAH biodegradation remains unclear. Here, p-hydroxybenzoate (pHBA), vanillate and methanol were selected to simulate phenolic units and methoxy groups of lignin.
