Surface engineering activation of mixed valence copper selenide: A high-performance anode for long life zinc-ion rock-chair batteries.

Rechargeable aqueous zinc-ion batteries (AZIBs) are an attractive alternative to lithium-ion batteries (LIBs) for large-scale energy storage, which offer high ionic conductivity and environmental advantages. However, challenges such as dendrite growth and limited coulombic efficiency (CE) limit electrochemical performance of AZIBs thus hindering their practical application. This study designs a polypyrrole (PPy)-coated copper selenide composite (CuSe@PPy) that works via Zn insertion/extraction mechanism.

One-Step Preparation of Both Micron and Nanoparticles.

The complex materials comprised of both micron and nanometer-sized particles (MNPs) present special properties different from conventional single-size particles due to their special size effect.

Cr-doped NiFe sulfides nanoplate array: Highly efficient and robust bifunctional electrocatalyst for the overall water splitting and seawater electrolysis.

To replace precious metals and reduce production costs for large-scale hydrogen production, developing stable, high-performance transition metal electrocatalysts that can be used in a wide range of environments is desirable yet challenging. Herein, a self-supported hybrid catalyst (NiFeCrS/NF) with high electrocatalytic activity was designed and constructed using conductive nickel foam as a substrate via manipulation of the cation doping ratio of transition metal compounds. Due to the strong coupling synergy between the metal sulfides NiS, FeS, and CrS, as well as their interaction with the conductive nickel foam (NF), the energy barrier for catalytic reactions is reduced, and the charge transfer rate is enhanced.

ROS play either positive or negative roles in various plant life activities as a two-edge sword. Class III peroxidase (CIII PRX) is a highly conserved antioxidant enzyme family specifically identified in plants, which is involved in maintaining ROS homeostasis in the cell and plays multiple functions in plant growth metabolism and stress response.

Enhancing the accuracy of blood-glucose tests by upgrading FTIR with multiple-reflections, quantum cascade laser, two-dimensional correlation spectroscopy and machine learning.

The accuracy of screening diabetes from non-diabetes is drastically enhanced by strategically upgrading the bench-marking infrared spectroscopy technique for non-invasive tests of blood-glucose, both with state-of-the-art instrumentation-retrofits and with intelligent spectral-datamining tools. First, the signal-to-noise performance of FTIR in measuring the spectral features of a glucose solution containing bovine serum albumin is improved by 2-3 times with the common single-pass attenuated total-reflection setup replaced by a multi-passes-reflections setup. Second, replacing the ordinary infrared lamp with a quantum cascade laser further improves the signal-to-noise by 3 times.

Tumor Cell-Specific Signal Processing Platform Controlled by ATP for Non-invasive Modulation of Cellular Behavior.

Regulating the spatial distribution of membrane receptors can artificially reprogram cellular behaviors, which play a critical biological role in various physiological and pathological processes. Herein, we construct a tumor cell-specific signal processing platform (TCS-SPP) for controlled promotion/inhibition of cellular-mesenchymal epithelial transition factor (c-Met) receptor dimerization to noninvasively modulate cellular behaviors. Upon the dual-aptamer recognition in the upstream input signal circuit (UISC) to discriminate target cancer cells, the membrane-anchored DNA signal processor (DSP) is activated for signal amplification via rolling circle amplification (RCA) followed by the working of an ATP molecular switch for signal conversion, achieving receptor modulation in the downstream output signal circuit (DOSC).

Diel asynchrony in the expanded characteristics of toxic cyanobacterial blooms revealed by integrated metabolomics and metagenomics.

We establish a field metabolomics protocol in Lake Taihu (China) and determined two critical parameters: the minimum amount of biomass for metabolomics and the daytime when metabolomes are stable. The minimum biomass is 475-950 µg dry weight (DW) or 204-408 ng DNA for F (phytoplankton) samples, and 940-1760 µg DW or 193-514 ng DNA for W (whole-water) samples. In a diel cycle, temporal taxonomical composition, metabolic state, and response to physiochemical factors progressed asynchronously between the F and W microbiomes.
