2D antiferromagnetic semiconducting FeCN with interesting properties.

Two-dimensional magnetic materials have demonstrated favorable properties (, large spin polarization and net magnetization) for the development of next-generation spintronic devices. The discovery of such materials and insight into their magnetic coupling mechanism has become a research focus. Here, on the basis of first-principles structural search calculations, we have identified a fresh FeCN monolayer consisting of edge-sharing Fe triangle sublattices and FeCN rings, which integrates antiferromagnetism, semiconductivity, and planarity.

An antiferromagnetic semiconducting FeCN monolayer with a large magnetic anisotropy and strong magnetic coupling.

Two-dimensional antiferromagnetic (AFM) materials with an intrinsic semiconductivity, a high critical temperature, and a sizable magnetic anisotropy energy (MAE) have attracted extensive attention because they show promise for high-performance spintronic nanodevices. Here, we have identified a new FeCN monolayer with a unique zigzag Fe chain through first-principles swarm structural search calculations. It is an AFM semiconductor with a direct band gap of 2.

Decompression with fusion versus decompression in the treatment of lumbar spinal stenosis: A systematic review and meta-analysis.

Objective: The goal of this study was to review relevant studies in order to determine the efficacy of decompression with fusion versus decompression in the treatment of lumbar spinal stenosis.

Methods: Using appropriate keywords, we identified relevant studies using PubMed, the Cochrane library, and Embase. Key pertinent sources in the literature were also reviewed, and all articles published through October 2019 were considered for inclusion.

Molecular evolution and sequence divergence of plant chalcone synthase and chalcone synthase-Like genes.

Plant chalcone synthase (CHS) and CHS-Like (CHSL) proteins are polyketide synthases. In this study, we evaluated the molecular evolution of this gene family using representative types of CHSL genes, including stilbene synthase (STS), 2-pyrone synthase (2-PS), bibenzyl synthase (BBS), acridone synthase (ACS), biphenyl synthase (BIS), benzalacetone synthase, coumaroyl triacetic acid synthase (CTAS), and benzophenone synthase (BPS), along with their CHS homologs from the same species of both angiosperms and gymnosperms. A cDNA-based phylogeny indicated that CHSLs had diverse evolutionary patterns.
