Defect-regulated MnS@NiCoSeS structures: A novel approach to unlock energy storage potential in supercapacitors.

Transition metal sulfides (TMSs) have significant potential in energy storage applications due to their high theoretical capacity and diverse reaction mechanisms. However, performance limitations in supercapacitors arise from various intrinsic defects, including low active material utilization and poor cycling stability caused by unstable electrical conductivity. To address these issues, this paper incorporates selenium atoms into sulfides, aiming to leverage selenium's high conductivity to enhance the electroactivity of transition metal sulfides.

Hollow NiS@CoS with core-satellite nanostructure derived from metal-organic framework (MOF)-on-MOF hybrids as an electrode material for supercapacitors.

Metal-organic frameworks (MOFs) have found wide applications in the field of supercapacitors due to their highly controllable porous structure, big specific surface area, and abundant chemical functional groups. MOF-on-MOF hybrids not only enhance the composition of MOFs (such as ligands and/or metal centers) but also provide greater structural diversity. By utilizing MOFs as precursors for preparing sulfides, the unique characteristics and inherent structure of MOFs are preserved but their conductivity and capacitance are enhanced.

Polyarylether-based COFs coordinated by Tb for the fluorescent detection of anthrax-biomarker dipicolinic acid.

In this study, a rare-earth hybrid luminescent material (lanthanide@COF) was constructed for the detection of a biomarker for anthrax (dipicolinic acid, DPA). JCU-505-COOH was prepared by the hydrolysis of the cyano group in JCU-505 a post-synthetic modification strategy, then the carboxyl groups in JCU-505-COOH coordinated with Tb ions, similar to pincer vising nut. The prepared Tb@JCU-505-COOH exhibited a turn-on response toward DPA, which allowed the lanthanide@COF to serve as a fluorescence sensor with excellent selectivity and high sensitivity (binding constant = 3.

Aggregation of egg white peptides (EWP) induced by proanthocyanidins: A promising fabrication strategy for EWP emulsion.

Egg-white peptides (EWP, <1 kDa) have been shown to possess various bioactive properties. However, poor emulsification of EWP limits its application in functional foods. In this study, EWP aggregation induced by proanthocyanidins (PC) contributed to the improvement of emulsion properties.

[A clinical study on combined serum hepatic fibrosis-related markers and ultrasound parameters to diagnose hepatic fibrosis].

Objective: This study attempted to explore the value of combining serum hepatic fibrosis-related markers and ultrasound parameters together on diagnosis of hepatic fibrosis.

Methods: Six serum markers and 8 ultrasound parameters were measured from 100 patients with chronic hepatitis B or cirrhosis. The results of the serum hepatic fibrosis-related markers and ultrasound in disease group were analyzed and compared with the findings of hepatic pathology.
