Bismuth oxychloride-bismuth oxide hybrid as a high-capacity anode material for aqueous alkaline battery.

A high-capacity and rate capability anode material is highly desired to improve the export performance of aqueous alkaline batteries (AABs). Due to the 3-electrons redox chemistry within a wide negative potential range, bismuth (Bi) based compounds are promising candidates as anode materials in AABs. A hybrid composed of different Bi-based compounds is envisioned to further reinforce the faradaic activity and affinity for electrolyte ions, thereby maximizing the charge storage capacity.

Single-atom "surgery" on chiral all-dialkynyl-protected superatomic silver nanoclusters.

The manipulation of single atom within the metallic kernel of nanoclusters has attracted considerable attention due to its potentials to elucidate kernel-based structure-property relationships at the single-atom level. Herein, new-designed chiral bialkynyl ligands, have been chosen as protective agents to isolate two pairs of 8-electron superatomic silver nanoclusters, R/S-Ag39 and R/S-Ag40. X-ray diffraction analysis reveals that Ag39 and Ag40 with the same number of chiral ligands, possess a closely analogous silver skeleton but a single-atomic difference.

Association of stress hyperglycemia ratio with presence and severity of chronic kidney disease among US adults with diabetes mellitus.

Background: Among diabetes mellitus (DM) patients, stress hyperglycemia ratio (SHR) is a strong predictor of short- and long-term prognosis, and adverse cardiovascular events. However, whether SHR is associated with increased risk of presence and severity of chronic kidney (CKD) disease remains undetermined.

Methods: Patients with DM from the National Health and Nutrition Examination Survey (NHANES) database (1999-2020) were included and divided into 5 groups according to their SHR level (quintile 1 to 5).

Epitaxial Growth of Silver Clusters from Ag57 to Ag72 via Laminating Multiple Different Anion Templates.

The established capability of anion templates in precisely manipulating the size, geometry, and function of metal clusters is well acknowledged. However, the development of a systematic methodology for orchestrating the assembly of silver clusters, particularly those encompassing multiple distinct types of anion templates, remains elusive due to the formidable synthetic challenge. In this work, we report two novel silver clusters, Ag57 and Ag72, using two and three different anion templates, respectively.

The RING-Type E3 Ligase BOI Interacts with EXO70E2 and Mediates Its Ubiquitination in .

In plants, the EXO70 proteins are important components of the exocyst complex and are involved in membrane trafficking, biotic and abiotic interactions, as well as cell wall formation. A previous study has indicated that a member of the EXO subfamily, EXO70E2, interacts with RIN4 to mediate plant immunity.

Preparation of alkyl microporous organic network-based capillary column for an efficient gas chromatographic separation of position isomers.

The large surface area, excellent thermal stability and easy modification make microporous organic networks (MONs) good candidates in the field of gas chromatography (GC). Due to the limited species and highly conjugated networks of MONs, their applications are still in infancy and restricted. To accelerate their developments and to enrich their types in GC, here we report the first example of synthesizing alkyl MON and its capillary column for GC separation of position isomers.

Vanadium-Silsesquioxane Nanocages as Heterogeneous Catalysts for Synthesis of Quinazolinones.

The functionalization of polyoxovanadate clusters is promising but of great challenge due to the versatile coordination geometry and oxidation state of vanadium. Here, two unprecedented silsesquioxane ligand-protected "fully reduced" polyoxovanadate clusters were fabricated via a facial solvothermal methodology. The initial mixture of the two polyoxovanadate clusters with different colors and morphologies (green plate and blue block ) was successfully separated as pure phases by meticulously controlling the assembly conditions.

Molybdenum iron carbide-copper hybrid as efficient electrooxidation catalyst for oxygen evolution reaction and synthesis of cinnamaldehyde/benzalacetone.

Oxygen evolution reaction (OER) is the efficiency limiting half-reaction in water electrolysis for green hydrogen production due to the 4-electron multistep process with sluggish kinetics. The electrooxidation of thermodynamically more favorable organics accompanied by CC coupling is a promising way to synthesize value-added chemicals instead of OER. Efficient catalyst is of paramount importance to fulfill such a goal.

Stool specimens were collected from patients with acute diarrhea, and RVA was detected and genotyped. The whole genome of RVA was sequenced by fragment amplification and Sanger sequencing.

Solvent-Mediated Hetero/Homo-Phase Crystallization of Copper Nanoclusters and Superatomic Kernel-Related NIR Phosphorescence.

Atomically precise superatomic copper nanoclusters (Cu NCs) have been the subject of immense interest for their intriguing structures and diverse properties; nonetheless, the variable oxidation state of copper ions and complex solvation effects in wet synthesis systems pose significant challenges for comprehending their synthesis and crystallization mechanism. Herein, we present a solvent-mediated approach for the synthesis of two Cu NCs, namely, superatomic and pure-Cu(I) . They initially formed as a hetero-phase and then separated as a homo-phase via modulating binary solvent composition.

Temperature-Controlled Selective Formation of Silver Nanoclusters and Their Transformation to the Same Product.

Herein, two atomically precise silver nanoclusters, Ag54 and Ag33, directed by inner anion templates (CrO and/or Cl), are initially isolated as a mixed phase from identical reactants across a wide temperature range (20-80 °C). Interestingly, fine-tuning the reaction temperature can realize pure phase synthesis of the two nanoclusters; that is, a metastable Ag54 is kinetically formed at a low temperature (20 °C), whereas such a system is steered towards a thermodynamically stable Ag33 at a relatively high temperature (80 °C). Electrospray ionization mass spectrometry illustrates that the stability of Ag33 is superior to that of Ag54, which is further supported by density functional theory calculations.

Molybdenum, tungsten doped cobalt phosphides as efficient catalysts for coproduction of hydrogen and formate by glycerol electrolysis.

Ectopic expression of the Arabidopsis mutant L3 NB-LRR receptor gene in Nicotiana benthamiana cells leads to cell death.

Nucleotide-binding sites and leucine-rich repeat proteins (NLRs) act as critical intracellular immune receptors. Previous studies reported an Arabidopsis-resistant gene L3 (AT1G15890), which encoded a coiled-coil (CC) NLR that conferred cell death in bacteria; however, its function in planta remains unclear. This study describes a comprehensive structure-function analysis of L3 in Nicotiana benthamiana.
