Preparation of TiCTMXene-based copper/cobalt composites for electrocatalytic ammonia synthesis.

MXenes represent exceptionally promising electrocatalytic materials for ammonia synthesis, owing to their outstanding electrical conductivity, modifiable surface functional groups, exceptional hydrophilicity, high specific surface area, and electronegative surface characteristics. In this investigation, we systematically demonstrate that the persistent challenge of Cu and Co nanoparticle agglomeration can be effectively addressed through the in-situ growth of bimetallic CuCo nanoparticles on TiCTMXene nanosheets. This innovative approach significantly enlarges the electrochemically active surface area, maximizes the exposure of catalytically active sites, and optimizes mass transport properties, consequently leading to substantially enhanced electrocatalytic performance for ammonia synthesis.

Comparison of angiographically derived coronary radial wall strain and superficial wall stress for the characterization of plaque vulnerability.

Background: Angiography-derived radial wall strain (RWS) estimates the radial coronary wall deformation caused by pulsatile blood pressure, whereas superficial wall stress (SWS) summarizes the comprehensive wall deformation caused by both blood pressure and cardiac motion. This study sought to investigate the difference between RWS and SWS for the association with plaque vulnerability and the impact of cardiac motion on RWS.

Methods: Concurrent RWS, cardiac motion-induced bending angle change (ΔCBA), SWS, and optical coherence tomography image analyses were retrospectively performed in 49 eligible intermediate coronary lesions.

Deciphering Cd stabilization pathways by organosilicon in soil-pakchoi systems through isotope-tracing.

Cadmium (Cd) pollution in farmland soils threatens food safety, making it essential to study soil-crop Cd transport mechanisms and develop remediation strategies. While organosilicon-modified materials demonstrate potential in blocking metal uptake by crops, their underlying mechanisms remain underexplored. This study employed stable isotope Cd tracing to investigate Cd absorption, translocation, allocation in soil-pakchoi system mediated by organosilicon (DMDCS and D6).

Case Report: Simnotrelvir/Ritonavir are effective in shortening the course of prolonged SARS-CoV-2 infection during anti-CD20 maintenance therapy in patients with follicular lymphoma.

Patients with hematologic malignancy had the possibility of persistent infection with COVID-19, particularly those who received anti-CD20 monoclonal antibody therapy for lymphoma, regardless of vaccination status. We report two cases of follicular lymphoma (FL) infected with Omicron virus that could not be confirmed by routine SARS-CoV-2 tests during maintenance therapy with an anti-CD20 agent, obinutuzumab or rituximab. In addition to immunomodulatory drugs, both of them took Simnotrelvir/Ritonavir to effectively alleviate the symptoms.

A salt-free medium facilitating electrode prelithiation towards fast-charging and high-energy lithium-ion batteries.

The substantial consumption of lithium ions and sluggish reaction kinetics at the anode detrimentally impact the deliverable energy and fast-charging capability of lithium-ion batteries with silicon-based anodes. The prevailing contact prelithiation method using an electrolyte medium can replenish the active lithium, but it may cause materials/electrode instability and bring barrier for lithium-ion transport. Here we explore a contact prelithiation methodology employing cyclic carbonate mediums that can enable spatially and temporally uniform prelithiation reaction.
