We explore the formation of single bilayer Sb(111) ultrathin film (Antimonene) on Bi2Te3 and Sb2Te3 substrates for first time, which is theoretically predicated to be a robust trivial semiconductor but can tuned 2D TI by reducing buckling height. From angle-resolved photoemission spectroscopy measurements, antimonene well grown two surfaces shows clear band dispersion. The electronic structure similar character surfaces, due interfacial strain effect, bands are flatter than Sb2Te3,...
Bacillus cereus is widely distributed in different food products and can cause a variety of symptoms associated with poisoning. Since ready-to-eat (RTE) foods are not commonly sterilized by heat treatment before consumption, B. contamination may severe safety problems.

Abstract Polar van der Waals chalcogenophosphates exhibit unique properties, such as negative electrostriction and multi-well ferrielectricity, enable combining dielectric 2D electronic materials. Using low temperature piezoresponse force microscopy, we revealed coexistence of piezoelectric non-piezoelectric phases in CuInP 2 Se 6 , forming unusual domain walls with enhanced response. From systematic imaging experiments have inferred the formation a partially polarized antiferroelectric...
Fischer–Tropsch synthesis (FTS) is a significant catalytic process for the production of liquid fuel and fine chemicals from natural gas-, coal-, biomass-derived syngas. However, exploring high-performance catalysts understanding mechanism remain challenging. Herein, we design Ru1Con single-atom alloy (SAA) catalyst with isolated Ru atoms anchored onto Co nanoparticle surface through two-dimensional confinement strategy to achieve greatly improved FTS activity (2.6 molCO molM–1 h–1)...
Cobalt-based catalysts have been widely used for Fischer-Tropsch synthesis (FTS) in industry; however, achieving rational catalyst design at the atomic level and thereby a higher activity more long-chain-hydrocarbon products simultaneously remain an attractive difficult challenge. The dual-atomic-site with unique electronic geometric interface interactions offer great opportunity exploiting advanced FTS improved performance. Herein, we designed Ru1Zr1/Co Ru Zr dual sites on Co nanoparticle...

From 1212 product samples, 362 (29.9%) were positive for monocytogenes. Serogroup analysis showed that the most prevalent serogroup of was I.1 (1/2a-3a), which accounted 45.0% (123/458) total, followed by I.2 (1/2c-3c) comprised 26.9%, II.1 (4b-4d-4e) 4.8%, II.2 (1/2b-3b-7) 23.3%....
Abstract Controlling electronic transport through a single-molecule junction is crucial for molecular electronics or spintronics. In magnetic devices, the spin degree-of-freedom can be used to this end since properties of ion centers fundamentally impact molecules. Here we demonstrate that electron pathway in device selected between two orbitals by varying field, giving rise tunable anisotropic magnetoresistance up 93%. The unique tunability pathways due reorientation transition metal...
Global electricity generation depends on cooling-reliant plants (78%), but rising temperatures could reduce their output. Steam-cycle air-cooling (ST-AC) technology, which is poorly adapted to high temperatures, widely used in power developing countries (40.7%) compared developed ones (25.2%). However, few studies have evaluated the performance of different cycle-cooling technologies under heat stress. Here, we a Power Plant Dataset comprising 109,110 thermal and nuclear units across six...

Creation of functional patterns in two-dimensional (2D) materials provides opportunities to extend their potential for applications. Transition-metal dichalcogenides (TMDCs) are suitable 2D pattern generation because properties including alterable polymorphic phases, easy chalcogen-vacancy formation, metal-atom insertion, and alloying.

Going against the grain: Normally, electric polarization of a ferroelectric compound switches to align itself with sufficiently strong applied field. Here authors report switching in van der Waals (vdW) crystals that is based on ion migration across vdW gap. This ionic mechanism complementary but fundamentally different from rotation underpinning usual picture switching. These findings change way we think about materials featuring both and dipolar properties enable fresh functionality...
The van der Waals layered material CuInP2S6 features interesting functional behavior, including the existence of four uniaxial polarization states, reversal against electric field through Cu ion migration, a negative-capacitance regime, and reversible extraction ions. At heart these characteristics lies high mobility ions, which also determines spontaneous polarization. Therefore, migration across lattice results in unusual ferroelectric behavior. Here, we demonstrate how interplay polar...
Ready-to-eat (RTE) vegetables have become increasingly popular along with the trend of moving towards a healthy lifestyle. However, RTE are at higher risk containing pathogens, maybe owing to lack rigorous sanitization procedures. To understand prevalence and potential Listeria monocytogenes in vegetables, we investigated contamination level characteristics L. isolated from fresh vegetables. Twenty-three (5.49%) 419 samples were positive for monocytogenes. Phylogenetic group I.1 (1/2a-3a)...
