Strained two-dimensional tungsten diselenide for mechanically tunable exciton transport.

Tightly bound electron-hole pairs (excitons) hosted in atomically-thin semiconductors have emerged as prospective elements in optoelectronic devices for ultrafast and secured information transfer. The controlled exciton transport in such excitonic devices requires manipulating potential energy gradient of charge-neutral excitons, while electrical gating or nanoscale straining have shown limited efficiency of exciton transport at room temperature. Here, we report strain gradient induced exciton transport in monolayer tungsten diselenide (WSe) across microns at room temperature via steady-state pump-probe measurement.

Discovery of Spirosnuolides A-D, Type I/III Hybrid Polyketide Spiro-Macrolides for a Chemotherapeutic Lead against Lung Cancer.

Four new macrolides, spirosnuolides A-D (-, respectively), were discovered from the termite nest-derived sp. INHA29. Spirosnuolides A-D are 18-membered macrolides sharing an embedded [6,6]-spiroketal functionality inside the macrocycle and are conjugated with structurally uncommon side chains featuring cyclopentenone, 1,4-benzoquinone, hydroxyfuroic acid, or butenolide moieties.

Efficacy and safety of rebamipide/nizatidine in patients with erosive gastritis: A randomized, multicenter, phase 4 study.

Background: For the treatment of gastritis, rebamipide, a mucoprotective agent, and nizatidine, a gastric acid suppressant, are commonly employed individually.

Aim: To compare the efficacy of Mucotra SR (rebamipide 150 mg) and Axid (nizatidine 150 mg) combination therapy with the sole administration of Axid in managing erosive gastritis.

Methods: A total of 260 patients diagnosed with endoscopically confirmed erosive gastritis were enrolled in this open-label, multicenter, randomized, phase 4 clinical trial, allocating them into two groups: Rebamipide/nizatidine combination twice daily nizatidine twice daily for 2 weeks.

Evaluating Nanofiltration and Reverse Osmosis Membranes for Pharmaceutically Active Compounds Removal: A Solution Diffusion Model Approach.

Trace organic contaminants (TrOCs), including pharmaceutically active compounds (PhACs), present significant challenges for conventional water treatment processes and pose potential risks to environmental and human health. To address these issues, nanofiltration (NF) and reverse osmosis (RO) membrane technologies have gained attention. This study aims to evaluate the performance of NF and RO membranes in removing TrOCs from wastewater and develop a predictive model using the Solution Diffusion Model.

ARS: AI-Driven Recovery Controller for Quadruped Robot Using Single-Network Model.

Legged robots, especially quadruped robots, are widely used in various environments due to their advantage in overcoming rough terrains. However, falling is inevitable. Therefore, the ability to overcome a falling state is an essential ability for legged robots.
