CoP-Enhanced CaTiO Single-Electron Oxygen Reduction Piezoelectric Catalysis for HO Production.

Piezoelectric catalytic production of HO is a novel and environmentally friendly HO production method, and many piezoelectric catalysts are currently being developed. However, all of them have the disadvantages of precious metals as cocatalysts and low catalytic efficiency. Herein, CaTiO was successfully prepared and loaded with the nonprecious metal CoP (CoP/CaTiO) for piezoelectric catalytic production of HO.

Machine Learning Supported the Modified Gustafson's Criteria for Dental Age Estimation in Southwest China.

Adult age estimation is one of the most challenging problems in forensic science and physical anthropology. In this study, we aimed to develop and evaluate machine learning (ML) methods based on the modified Gustafson's criteria for dental age estimation. In this retrospective study, a total of 851 orthopantomograms were collected from patients aged 15 to 40 years old.

Artificial Surface Electron Network Prompted Energy Band Structure Tuning: Boosting Solar-to-Hydrogen Evolution Performance.

The energy gap and conduction band position of catalysts play crucial roles in solar-to-hydrogen (STH) transformation technology. Unfortunately, although an increase in the conduction band position can effectively promote the photoreduction capacity of the photocatalyst, it will inevitably widen the band gap, thus reducing the light-absorption scale. It seems that there is a contradiction between the reduction of band gap and the improvement of conduction band position, which is that "You can't have your cake and eat it too.

Machine learning and deep learning enabled age estimation on medial clavicle CT images.

The medial clavicle epiphysis is a crucial indicator for bone age estimation (BAE) after hand maturation. This study aimed to develop machine learning (ML) and deep learning (DL) models for BAE based on medial clavicle CT images and evaluate the performance on normal and variant clavicles. This study retrospectively collected 1049 patients (mean± SD: 22.

Forensic age estimation in adults by pubic bone mineral density using multidetector computed tomography.

Radiology plays a crucial role in forensic anthropology for age estimation. However, most studies rely on morphological methods. This study aims to investigate the feasibility of using pubic bone mineral density (BMD) as a new age estimation method in the Chinese population.

Protective effect of omega-3 polyunsaturated fatty acids on sepsis via the AMPK/mTOR pathway.

Context: Sepsis is a systemic inflammatory response caused by infection, with high morbidity and mortality. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) have reported biological activities.

Objective: This study explored the signaling pathways through which ω-3 PUFAs protect against sepsis-induced multiorgan failure.

In Vitro Efficacy of Targeted Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols Enzymatic Digestion in a High-Fidelity Simulated Gastrointestinal Environment.

Background And Aims: Irritable bowel syndrome (IBS) is characterized by abdominal pain and changes in bowel habits. Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) are poorly absorbed short-chain carbohydrates that may drive commensal microbial gas production, promoting abdominal pain in IBS. Low-FODMAP diet can result in symptomatic improvement in 50%-80% of IBS patients.

Interfacial modification and band modulation for dramatically boosted photocatalytic hydrogen evolution.

Interfacial modification and band modulation to narrow the band gap and improve light-harvesting ability of TiO are promising strategies to dramatically promote photocatalytic activity. Herein, efficient Co(OH)-TiO nanocomposites were reasonably designed and constructed by a facile room temperature solid-state synthetic strategy for interfacial modification and matched band gap to achieve the conversion of solar energy to hydrogen. Modifying transition metal hydroxide Co(OH) on commercial TiO can effectively narrow the band gap and accelerate the separation and migration of photo-induced carriers, which will extend light absorption range and facilitate more electrons transferring to the surface of photocatalyst, therefore the reducibility of photocatalysts is enhanced.

Graphene Quantum Dot Reinforced Electrospun Carbon Nanofiber Fabrics with High Surface Area for Ultrahigh Rate Supercapacitors.

High surface area, good conductivity, and high mechanical strength are important for carbon nanofiber fabrics (CNFs) as high-performance supercapacitor electrodes. However, it remains a big challenge because of the trade-off between the strong and continuous conductive network and a well-developed porous structure. Herein, we report a simple strategy to integrate these properties into the electrospun CNFs by adding graphene quantum dots (GQDs).
