Objective: To investigate the distribution of carbapenem-resistant Enterobacterales (CRE) in the community and to describe the genomic characteristics.
Methods: CRE screened from fecal samples in healthy people at the health examination center of a tertiary hospital in China underwent Whole genome sequencing (WGS) to analyze genotypic characteristics of CRE. The flanking DNA sequence of blaNDM-5 and mcr1.
Objective: To investigate the clinical and molecular characteristics of spp. causing bloodstream infections (BSIs) in our hospital.
Methods: We studied 22 clinical isolates from BSIs and 16 from non-BSIs, performing antimicrobial susceptibility testing (AST) and whole genome sequencing (WGS).
Article Synopsis
- Piezoelectric materials, especially perovskite ferroelectrics, are crucial for various technologies, with growing needs for lightweight, flexible, and biocompatible options.
- Hybrid organic-inorganic perovskite ferroelectrics, particularly rare-earth double perovskites, show promising ferroelectricity but have not been fully explored for piezoelectric applications.
- Research indicates that these materials can achieve large piezoelectric responses through the coexistence of ferroelectric and paraelectric phases, allowing easy polarization rotation under stress, marking a significant advancement in lead-free piezoelectric materials.
As a major branch of hybrid perovskites, two-dimensional (2D) hybrid double perovskites are expected to be ideal systems for exploring novel ferroelectric properties, because they can accommodate a variety of organic cations and allow diverse combinations of different metal elements. However, no 2D hybrid double perovskite ferroelectric has been reported since the discovery of halide double perovskites in the 1930s. Based on trivalent rare-earth ions and chiral organic cations, we have designed a new family of 2D rare-earth double perovskite ferroelectrics, AMM(NO), where A is the organic cation, M is the alkaline metal or ammonium ion, and M is the rare-earth ion.

However, this method cannot be extended effectively to hybrid antiperovskites. Now, the design of hybrid antiperovskites under the guidance of the concept of Goldschmidt's tolerance factor is presented.
