The application of HEAs in mimicking complex enzymatic systems remains relatively unexplored, despite the importance of regulating biological redox reactions.

The Prognostic Values of Serum Liver Enzymes in Intrahepatic Cholangiocarcinoma Patients After Liver Resection: A Multi-Institutional Analysis of 605 Patients.

Purpose: The value of liver enzymes, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT), in predicting the prognosis of intrahepatic cholangiocarcinoma (ICC) patients who underwent curative resection has not been elucidated. Therefore, we aimed to construct prognostic nomograms for surgically treated ICC patients.

MoP assists the promotion on FeP and FeN for oxygen reduction and zinc-air battery.

It is of great significance but remains challenging to simultaneously development cost-effective and efficient non-noble metal electrocatalysts (NNMEs) for oxygen reduction reaction (ORR) in both alkaline and acidic solutions. In current work, a multi-component synergism system is developed, which is comprised of molybdenum phosphide (MoP) shell onto iron phosphide clusters anchored on carbon matrixes that embedded with numerous FeN species (MoP/FeP-FeN). The optimized MoP/FeP-FeN electrocatalyst delivers a synergistic enhancement in both alkaline and acidic ORR performances: E: 0.

Pioneering Built-In Interfacial Electric Field for Enhanced Anion Exchange Membrane Water Electrolysis.

As a half-reaction in anion exchange membrane water electrolysis (AEMWE) technology, the hydrogen evolution reaction (HER) at the cathode is severely hindered by the sluggish reaction kinetics involved in additional water dissociation step, which results in large overpotentials and low energy conversion efficiency. Here, we develop a nano-heterostructure composed of ultra-thin WN shells over NiN nanoparticles (NiN@WN) as efficient catalysts, in which built-in interfacial electric field (BIEF) is created owing to the distinct lattice arrangements and work functions of biphasic metal nitrides. The BIEF facilitates the electron localization around the interface and enables high valence W and more exposed binding sites in the surface WN shell for accelerating the water dissociation step, ultimately leading to a remarkable reduction in the energy barriers of RDS from 1.

A Versatile Redox-Active Electrolyte for Solid Fixation of Polyiodide and Dendrite-Free Operation in Sustainable Aqueous Zinc-Iodine Batteries.

Practical utilization of zinc-iodine (Zn-I) batteries is hindered by significant challenges, primarily stemming from the polyiodide shuttle effect on the cathode and dendrite growth on the anode. Herein, a feasible redox-active electrolyte has been introduced with tetraethylammonium iodide as an additive that simultaneously addresses the above mentioned challenges via polyiodide solidification on the cathode and the electrostatic shielding effect on the anode. The tetraethylammonium (TEA) captures water-soluble polyiodide intermediates (I , I ), forming a solid complex at the cathode, thereby suppressing capacity loss during charge/discharge.

Manipulation of Oxidation States on Phase Boundary via Surface Layer Modification for Enhanced Alkaline Hydrogen Electrocatalysis.

In alkaline water electrolysis and anion exchange membrane water electrolysis technologies, the hydrogen evolution reaction (HER) at the cathode is significantly constrained by a high energy barrier during the water dissociation step.

This work systematically modulates the oxidation states of W within the amorphous WO of the heterostructure to adjust the electronic states of the phase boundary, the energy barriers associated with the water dissociation step, and the adsorption/desorption properties of intermediates during the alkaline HER process.

Interpretable Data-Driven Descriptors for Establishing the Structure-Activity Relationship of Metal-Organic Frameworks Toward Oxygen Evolution Reaction.

The development of readily accessible and interpretable descriptors is pivotal yet challenging in the rational design of metal-organic framework (MOF) catalysts. This study presents a straightforward and physically interpretable activity descriptor for the oxygen evolution reaction (OER), derived from a dataset of bimetallic Ni-based MOFs. Through an artificial-intelligence (AI) data-mining subgroup discovery (SGD) approach, a combination of the d-band center and number of missing electrons in e states of Ni, as well as the first ionization energy and number of electrons in e states of the substituents, is revealed as a gene of a superior OER catalyst.

Amorphous MnRuO Containing Microcrystalline for Enhanced Acidic Oxygen-Evolution Activity and Stability.

Compared to Ir, Ru-based catalysts often exhibited higher activity but suffered significant and rapid activity loss during the challenging oxygen evolution reaction (OER) in a corrosive acidic environment. Herein, we developed a hybrid MnRuO catalyst in which the RuO microcrystalline regions serve as a supporting framework, and the amorphous MnRuO phase fills the microcrystalline interstices. In particular, the MnRuO-300 catalyst from an annealing temperature of 300 °C contains an optimal amorphous/crystalline heterostructure, providing substantial defects and active sites, facilitating efficient adsorption and conversion of OH.

Corylifol A suppresses osteoclastogenesis and alleviates ovariectomy-induced bone loss via attenuating ROS production and impairing mitochondrial function.

Osteoporosis is a systemic disease characterized by an imbalance in bone homeostasis, where osteoblasts fail to fully compensate for the bone resorption induced by osteoclasts. Corylifol A, a flavonoid extracted from Fructus psoraleae, has been identified as a potential treatment for this condition. Predictions from network pharmacology and molecular docking studies suggest that Corylifol A exhibits strong binding affinity with NFATc1, Nrf2, PI3K, and AKT1.

Although OP in men is common, it has received much less attention than that in women. Ginseng, a famous traditional herb in Asia, is used to strengthen and repair bones by invigorating vital bioenergy and maintaining body homeostasis in dietary intake and clinical applications.
