Stress Regulation through Precursor Chemistry: From Synthesis to Cycling Stability in O3‐Type Layered Oxide Cathodes

ABSTRACT Layered oxide cathode materials have broad application prospects in sodium‐ion batteries. However, conventional oxide solid‐state synthesis route, transition metal oxides slowly participate in the reaction step by step, causing residual stress accumulation and cycling de...

Field-based vital-capacity changes following a 12-week athletic skills model-informed curriculum: a retrospective non-randomised comparison in one Chinese primary school

This retrospective non-randomised comparison examined routine school records from 1,214 students in Grades 2–6 (607 per condition) in one urban public primary school in Southwest China. Curriculum allocation occurred at the level of 28 pre-existing physical-education (PE) teachin...

LSTM-based prediction and parameter optimization analysis of sandstone subgrade compaction quality

The study proposes an LSTM-based framework for next-pass Compaction Energy Value (CEV) prediction and subsequent energy planning during sandstone subgrade compaction. Field tests were conducted at two sites, each divided into 24 spatial areas. For each completed compaction pass,...

Reconstruction of soil microbiome and elemental cycling by a synthetic microbial community: A sustainable strategy for improving paddy soil fertility and rice production under agrochemical reduction

Intensive rice cultivation often relies on substantial agrochemical inputs to maintain soil fertility and crop productivity, creating challenges for sustainable paddy management. In the present study, a field trial combined with metagenomic sequencing was performed to uncover the...

Analysis of the Characteristics of a Microburst Event at Urumqi Airport Based on Microwave Radiometer and Doppler Wind Lidar

Microbursts can cause severe low-level wind shear, posing a threat to aviation safety. However, due to their small scale, they are difficult to capture by conventional equipment such as surface Automated Weather Observing Systems (AWOS) and Doppler weather radar. On 25 June 2022,...

Synthesis, Characterization, and Potential Application of Phosphoramide Derivatives as Nitrocellulose Stabilizers

ABSTRACT A series of phosphoramide derivatives were synthesized using POCl 3 and aniline as raw materials. The phosphoramide derivatives can inhibit the self‐catalytic decomposition of nitrocellulose (NC), thereby extending the service life of nitrate‐based propellants. The struc...

National-scale hydroclimatic exposure screening of earthen heritage sites in China under changing precipitation regimes

Earthen heritage sites are highly sensitive to rainfall-induced erosion and moisture-related deterioration, yet their national-scale hydroclimatic exposure remains insufficiently quantified. Here, we compiled a geospatial database of 1,305 national-level earthen heritage sites in...

Controllable Reconstruction of the Ni/MgAl2O4 Catalyst by In Situ Liquid-Phase Reduction Combined with an Adsorption-Impregnation Strategy to Enhance Reaction Performance for MCH Steam Reforming

Abstract Hydrogen production via catalytic steam reforming of high-carbon hydrocarbons, with low cost, strong adaptability, and easy industrialization, is one of the core technologies for addressing the hydrogen supply bottleneck of fuel cells. However, traditional synthesis meth...

Multi‐Channel Holography Enabled by Interlayer‐Correlated Liquid Crystal Elements for Nested Optical Encryption

ABSTRACT Liquid crystal (LC) planar devices have emerged as an attractive ultra‐thin platform for optical encryption. However, most existing LC‐based holographic encryption schemes rely on conventional multiplexing strategies with limited design freedom and weak interlayer collab...

Construction of In Vitro-In Vivo Correlation (IVIVC) Degradation Evaluation Model of Absorbable PCL/β-TCP Alveolar Bone Repair Scaffold and Exploration of a Biosafety Evaluation Idea Based on “Homeostasis”

Abstract Traditional in vivo degradation assessments for resorbable medical devices face challenges due to extreme durations, high costs, and a lack of criteria for reaching tissue-response steady states. This study investigates a 3D-printed PCL/β-TCP bone grafting scaffold by de...

EPI-Sense: an integrated hemodynamic sensing and analysis system for early pressure injury warning

Pressure injury poses a critical challenge in geriatric care. Current computer-aided diagnosis is limited by an exclusive reliance on surface texture, neglecting subcutaneous hemodynamics essential for distinguishing Reactive Hyperemia from Stage 1 PI and detecting Deep Tissue Pr...
