Designing Ru-B-Cr Moieties to Activate the Ru Site for Acidic Water Electrolysis under Industrial-Level Current Density.
Nano Lett
December 2024
Alan G. MacDiarmid Institute, College of Chemistry, Jilin University, 2699 Qianjin Street, Changchun 130012, P. R. China.
Developing highly efficient non-iridium-based active sites for acidic water splitting is still a huge challenge. Herein, unique Ru-B-Cr moieties have been constructed in RuO nanofibers (NFs) to activate Ru sites for water electrolysis, which overcomes the bottleneck of RuO-based catalysts usually possessing low activity for the hydrogen evolution reaction (HER) and poor stability for the oxygen evolution reaction (OER). The fabricated Cr, B-doped RuO NFs exhibit low overpotentials of 205 and 379 mV for acidic HER and OER at 1 A cm with outstanding stability lasting 1000 and 188 h, respectively.

Triangular Au and tetrahedral Au are key structural units in the face-centered cubic gold core of thiolate-protected gold nanoclusters. Understanding their stacking arrangements is essential for elucidating the growth mechanisms of these gold cores. In this study, we design two new isomers of Au(SR) nanoclusters via deliberately adjusting the stacking pattern of Au and Au based on the grand unified model and ring model to show preferable packing arrangements.

December 2024
Department of Obstetrics and Gynecology, The International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, 200030, China.
Objective: Endometrial cancer (EC) is the ninth most common malignancy among women. While mutations in JAK2 are frequently observed in EC, the specific biological functions of JAK2 in endometrial cancer are poorly understood.
Methods: The genetic alterations of JAK2 in different cancer types were explored using sequencing dataset deposited at TCGA database.
Closing the loops: chromatin loop dynamics after DNA damage.
Nucleus

Department of Biology, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.
Chromatin is a dynamic polymer in constant motion. These motions are heterogeneous between cells and within individual cell nuclei and are profoundly altered in response to DNA damage. The shifts in chromatin motions following genomic insults depend on the temporal and physical scales considered.

Physiother Theory Pract
December 2024
Department of Physiotherapy and Rehabilitation, Atlas University, Istanbul, Turkey.
Background: Dual-task activities, which involve performing two separate tasks simultaneously, often result in reduced motor function and daily activity performance among individuals with knee osteoarthritis (OA).
Objective: This study aimed to investigate the impact of single- and dual-task conditions on muscle strength and performance in individuals with knee OA and examine how cognitive load influences physical task performance in this population.
Methods: Sixty patients with knee OA were included.
