Synergy of Ag and Interfacial Oxygen Vacancies on TiO for Highly Efficient Photocatalytic Production of HO.

Photocatalytic HO production stands as a promising sustainable technology for chemical synthesis. However, rapid charge recombination and limited oxygen adsorption by photocatalysts often limit its efficiency. Herein, we demonstrate that the synergy of Ag and interfacial oxygen vacancies on TiO could overcome these challenges.

Linking the Doping-Induced Trap States to the Concentration of Surface-Reaching Photoexcited Holes in Transition-Metal-Doped TiO Nanoparticles.

Transition-metal doping has been demonstrated to be effective for tuning the photocatalytic activity of semiconductors. Nonetheless, the impact of doping-induced trap states on the concentration of surface-reaching photoexcited charges remains a topic of debate. In this study, through time-resolved spectroscopies and kinetic analysis, we found that the concentration of surface-reaching photoholes () in doped TiO nanoparticles sensitively relies on the type of dopants and their associated trap states.

Hsa_circ_0015382 is involved in the pathogenesis of preeclampsia by mediating THBS2 expression.

Background: Preeclampsia (PE) is a hypertensive disorder of pregnancy that causes significant maternal and perinatal morbidity and mortality. Circular RNA (circRNA) hsa_circ_0015382 is associated with the pathogenesis of PE, but its underlying regulatory mechanism remains to be explored.

Methods: Relative RNA levels of hsa_circ_0015382, microRNA-616-3p and thrombospondin-2 (THBS2) were detected by quantitative reverse transcription-polymerase chain reaction.

Synergy of Bulk Defects and Surface Defects on TiO for Highly Efficient Photocatalytic Production of HO.

Artificial photosynthesis of HO by TiO-based semiconductors is a promising approach for HO production. However, the efficiency of pristine TiO is still limited by rapid charge separation and low O adsorption capacity. Here, we found that the synergy between bulk and surface defects on TiO could overcome this demanding bottleneck.

Urban-Rural Differences in Physical Fitness and Out-of-School Physical Activity for Primary School Students: A County-Level Comparison in Western China.

Rapid urbanization of China has brought lifestyle changes resulting in a continuous decline in children's physical fitness (PF) and out-of-school physical activity (PA). To date, studies have been focused on correlates of PF and out-of-school PA, and patterns and trends based on geographic diversity and urban-rural contrasts. Western China, with a large rural population, has substantial urban-rural differences, but little work has been done to compare its children's physical fitness (PF) and out-of-school physical activity (PA) at a county level.

Fluorescence enhancement of gold nanoclusters Zn doping for biomedical applications.

Gold nanoclusters (NCs) have been widely used in bioimaging and cancer therapy due to their unique electronic structures and tunable luminescence. However, their weak fluorescence prevents potential biomedical application, and thus it is necessary to develop an effective route to enhance the fluorescence of gold NCs. In this work, we report the fluorescence enhancement of ultrasmall GSH-protected Au NCs by Zn atom doping.

Hollow PtPdRh Nanocubes with Enhanced Catalytic Activities for In Vivo Clearance of Radiation-Induced ROS via Surface-Mediated Bond Breaking.

Catalytic nanomaterials can be used extrinsically to combat diseases associated with a surplus of reactive oxygen species (ROS). Rational design of surface morphologies and appropriate doping can substantially improve the catalytic performances. In this work, a class of hollow polyvinyl pyrrolidone-protected PtPdRh nanocubes with enhanced catalytic activities for in vivo free radical scavenging is proposed.

Ultrasmall Pt Clusters Reducing Radiation-Induced Injuries via Scavenging Free Radicals.

High energy ionizing radiation was widely used in medical diagnosis and cancer radiation therapy. The high dose of X ray or ray can cause the damage of cancerous tissue as well as healthy tissue during therapy. Therefore, it is urgent to develop chemical agents to protect the healthy tissue from high energy ray invasion.

Diagnostic value of strain elastography for differentiating benign and malignant soft tissue masses.

The aim of the current study was to investigate the importance of strain elastography (SE) in the differential diagnosis of benign and malignant soft tissue masses. SE was adopted to examine 61 patients with superficial masses, classify their elastic scores and assess their strain ratios (SRs) between the masses and the surrounding structures. Significantly increased SR values and elastic scores were observed in the malignant masses compared with the benign masses (5.

Black Phosphorus Quantum Dot Induced Oxidative Stress and Toxicity in Living Cells and Mice.

Black phosphorus (BP), as an emerging successor to layered two-dimensional materials, has attracted extensive interest in cancer therapy.
