Harnessing the Interface of Water Microdroplets to Accelerate Energy Substance Adenosine Triphosphate Formation.

Adenosine triphosphate (ATP) as an energy source plays a key role in providing and regulating energy for life activities in all organisms. Abiotic synthesis of ATP in vitro remains a challenge due to thermodynamic and kinetic constraints in water bulk solution. Here, we report that adenosine diphosphate (ADP) in the presence of potassium phosphate (KPO) spontaneously generates ATP in water microdroplets under ambient conditions and without catalysts.

Accurate POI recommendation for random groups with improved graph neural networks and a multi-negotiation model.

In recent years, the growing prevalence of group activities has brought increased interest in Point of Interest (POI) recommendations for groups. While significant progress has been made in recommending POIs for fixed groups, research on personality-aware recommendations for random groups has been still largely untouched. Moreover, existing works recommend a POI list for a group and the group makes further choice of the optimal POI, which results in poor user experience.

Enhancing the Performance of Fluorinated Graphdiyne Moisture Cells via Hard Acid-Base Coordination of Aluminum Ions.

Moisture-enabled electric generators (MEGs) are emerging as a transformative energy technology, capable of directly converting ambient moisture into electrical energy without producing pollutants or harmful emissions. However, the widespread application of MEGs is hindered by challenges such as intermittent output and low current densities, which limit power density and prevent large-scale integration. Here, a novel moisture cell based on Al ion-F coordination-specifically, a fluorinated graphdiyne (FGDY) Al-ion moisture cell (FGDY AlMC) is introduced.

Examining the impact of perceived behavioral control and planning on closing the exercise intention-behavior gap: Insights from a meta-analytic structural equation modeling study.

Objective: This study aims to investigate the roles of perceived behavioral control (PBC), action planning, and coping planning in bridging the gap between exercise intention and behavior. By using a Meta-Analytic Structural Equation Model (MASEM), we quantify the specific effects of these variables and explore their mediating roles in the relationships between intention, PBC, and behavior. The study provides insights into how these constructs contribute to informing effective behavioral intervention strategies.

Surface immobilization of single atoms on heteroatom-doped carbon nanospheres through phenolic-mediated interfacial anchoring for highly efficient biocatalysis.

Single-atom catalysts (SACs) dispersed on support materials exhibit exceptional catalytic properties that can be fine-tuned through interactions between the single atoms and the support. However, selectively controlling the spatial location of single metal atoms while simultaneously harmonizing their coordination environment remains a significant challenge. Here, we present a phenolic-mediated interfacial anchoring (PIA) strategy to prepare SACs with Fe single atoms anchored on the surface of heteroatom-doped carbon nanospheres.

Water Microdroplets Promote Spontaneous Oxidation of Amino Acid- and Peptide-related Thiols to Disulfide Bonds.

Disulfide bonds (S-S) play a critical role in modern biochemistry, organic synthesis and prebiotic chemistry. Traditional methods for synthesizing disulfide bonds often rely on oxygen, alkali, and metal catalysts. Herein, thiol groups involved in amino acids and peptides were spontaneously converted into symmetrical and unsymmetrical disulfide bonds within water microdroplets, without the need for catalysts or oxygen, and under room temperature.

Can exercise as a complementary technique manage inflammatory markers in women with breast cancer who are overweight and obese? A systematic review and meta-analysis.

Background: Inflammation can result in the development of breast cancer in women with overweight and obese, and also affects the outcome and prognosis of breast cancer patients, thereby decreasing the cure and survival rates of breast cancer patients. Exercise may benefit breast cancer patients as a supplement to conventional treatments. However, research on the effects of exercise on inflammatory markers in women with breast cancer who are overweight and obese remains incomplete.

Establishment of a detection method for Prorocentrum minimum by nuclease protection-based nucleic acid chromatography strip.

A detection method, named as nuclease protection-nucleic acid chromatography strip assay (NP-NACSA), was established to detect Prorocentrum minimum, a common harmful algal blooms-forming algal species. In this study, the developed NP-NACSA requires no nucleic acid amplification, but directly targets rRNA obtained from broken cells. After converting the target rRNA to DNA by nuclease protection, the resultant DNA is automatically analyzed by nucleic acid chromatography strip.

Enhanced Photodetection Performance of InBiSe/ReS Polarization-Sensitive Heterostructure Photodetectors.

Individual anisotropic two-dimensional (2D) materials have been widely applied for developing polarization-sensitive photodetectors, but they often suffer from limitations in photoresponsivity, detection range, etc. To overcome these challenges, van der Waals (vdW) heterostructures created by stacking different 2D materials provide a promising solution to enhance the performance of the photoelectronic device. In this work, a novel polarization-sensitive photodetector is developed by leveraging a heterojunction formed by InBiSe and anisotropic ReS nanoflakes.

At the end of 48 h discharging, µDMFCs with porous stainless-steel plates between MEA and PCB coating achieved higher performance than those of the direct contacting series.

Fatigue Crack Monitoring Method Based on the Lamb Wave Damage Index.

For practical engineering structures, fatigue is one of the main factors affecting their safety and durability. Under long-term service conditions, the minor damage will be affected by fatigue loading and expand to macroscopic cracks, affecting the structure's service performance. Based on the sensitivity of Lamb waves to minor and initial damage, a damage monitoring method for fatigue crack propagation is proposed.

Rational design of structure-based vaccines targeting misfolded alpha-synuclein conformers of Parkinson's disease and related disorders.

Synucleinopathies, including Parkinson's disease (PD), multiple system atrophy (MSA), and dementia with Lewy bodies (DLB), are neurodegenerative disorders caused by the accumulation of misfolded alpha-synuclein protein. Developing effective vaccines against synucleinopathies is challenging due to the difficulty of stimulating an immune-specific response against alpha-synuclein without causing harmful autoimmune reactions, selectively targeting only pathological forms of alpha-synuclein. Previous attempts using linear peptides and epitopes without control of the antigen structure failed in clinical trials.
