Exploring hydrogen production from plastic waste for urban transportation in Hong Kong and its environmental impact mitigation: integrating dynamic material flow analysis and life cycle assessment

Plastic waste to hydrogen technology offers a sustainable clean energy pathway while reducing landfill and incineration burdens. However, its feasibility as a feedstock for urban mobility decarbonization at the city scale remains largely unexplored. Hong Kong, as a densely popula...

Net carbon emission accounts, drivers, and mitigation measures in China, 1980–2020

Mitigating net CO 2 emissions under socioeconomic development and climate variability is essential for climate action and sustainable development goals. Here, focusing on anthropogenic emissions and terrestrial ecosystem sinks, we construct a national-scale account of China's net...

The effects of CeFe2 phase distribution and magnetic transition on the magnetic behavior of hot-deformed Ce16Fe76Cu2B6 magnet

Tailoring the high-melting-point CeFe2 phase is an effective strategy for optimizing the magnetic performance of Ce–Fe–B permanent magnets. Further property enhancement can also be achieved by modifying the distribution, morphology, and magnetic state of the grain-boundary phases...

Explainable machine learning model based on cardiac CT angiography for predicting functional improvement after atrial fibrillation ablation: a multicenter study

Radiofrequency ablation is an established therapy for atrial fibrillation (AF), but outcomes are heterogeneous in patients with concomitant heart failure (HF). Therefore, we aimed to develop an explainable machine learning (ML) model based on cardiac CT angiography (CTA) for pred...

Differences in spatial patterns of inter-city travel from the perspective of traffic networks: New energy vehicles versus fuel vehicles

Investigating the spatial pattern differences in inter-city travel between new energy vehicles (NEVs) and conventional fuel vehicles (FVs) is essential to evaluate the progress of NEV adoption and inform policy-making for transportation decarbonization. To distinguish NEVs from F...

Osteoclastogenesis with FN1-associated cell differentiation, immune communication, and ECM remodeling in male SAMP6 mice

Early diagnosis and precise treatment of senile osteoporosis remain challenging. Herein, we apply a multi-omics strategy, integrating scRNA-seq and proteomics in the male 5-month-old senescence-accelerated mouse prone 6 (SAMP6) spontaneous aging model, to study early bone loss. T...

Thermal‑sprayed WC‑NiMoCrFeCo/vapor‑deposited DLC with a composition‑structure dual‑gradient transition layer: Synergistic corrosion and wear protection for marine environments

To tackle the synergistic corrosion‑wear degradation of moving components in marine environments, we propose a composite coating system consisting of a WC‑NiMoCrFeCo (WN) underlayer, a diamond‑like carbon (DLC) top coat, and a composition‑structure multi-gradient transition layer...

Egg volatiles of oak silkworm mediate defense against parasitoid wasps

Most insects protect their eggs from natural enemies via physical coverings, yet defensive mechanisms of exposed eggs (i.e., those without such coverings), particularly those lacking toxins, remain largely unexplored. The oak silkworm (Antheraea pernyi) lays such exposed eggs, ye...

Dual effect of calcium ions on sodium oleate adsorption and spodumene flotation

The flotation of spodumene with sodium oleate is highly sensitive to calcium concentration, but the underlying interfacial mechanisms remain unclear, especially under inhibitory conditions. To address this, we systematically investigate how calcium ions govern the spodumene-oleat...

Visualizing Heteroepitaxy of Angle-Oriented GeSe/WSe2 Heterostructures for Near-Infrared Ultrasensitive Photodetectors

Abstract Precise heteroepitaxial control in van der Waals (vdW) heterostructures remains a challenge. Here, we demonstrate a visualized and directed heteroepitaxy strategy for GeSe on WSe2 by integrating in situ imaging with symmetry-guided physical vapor deposition. Real-time ob...

Elevation Amplifies Carrier-Type Differences in Nitrogen Cycling and N 2 O Dynamics in Lake Biofilms

Abstract Lake biofilms are microbial habitats for nitrogen transformation, but how carrier type and elevation influence N2O dynamics remains unclear. We examined abiotic- and biotic-carrier biofilms from 12 lakes spanning 4–4272 m using anoxic incubations, 15N tracing, selective...

Ecological fitting in a deceptive trap flower: Aristolochia gibertii recruits native drosophilid flies outside South America

Deceptive pollination, in which plants lure pollinators without offering rewards, represents a sophisticated evolutionary strategy. The trap-flowers of Aristolochia provide an excellent system to study the coordinated evolution of floral morphology, chemistry, and phenology. Howe...

Magnesium-induced changes in soil chemical and microbial properties facilitate improvements in sugarcane yield and fertilizer use efficiency

Soil magnesium (Mg) deficiency limits sugarcane yield and quality, underscoring the need for optimized Mg fertilization. A field experiment was conducted to compare the effects of three types of Mg fertilizer (magnesium sulfate, silicon-magnesium, and boron-magnesium-zinc) on sug...

Neutron diffraction investigation of residual stress and texture in additively manufactured AISI 410 and 316L steel plates produced by LPBF and DED

Residual stresses pose a significant challenge in additive manufacturing, particularly for large metal parts. Monitoring these stresses is essential to achieving reliable performance characteristics. Neutron diffraction—a nondestructive method that measures residual stresses thro...

Effect of Al-8Sr-8Ce master-alloy content on microstructure and mechanical properties of Al-15Mg2Si alloy

Al-Mg 2 Si alloys exhibit broad application prospects in automotive, aerospace, and electronics fields. However, the coarse morphology of Mg 2 Si constrains their applications. In this study, an Al-8Sr-8Ce modifier was proposed to improve the Mg 2 Si morphology and mechanical pro...

The Rhizosphere Microbiome: A Key Mediator of Crop Responses to Fertilization Strategies

The rhizosphere microbiome, the plant’s “second genome” is pivotal for crop nutrient acquisition, health, and stress responses. While fertilization ensures high agricultural yields, a key challenge is reshaping this microbiome to boost crop performance. This review synthesizes ho...

Flavonoid Biosynthesis Mediated by GmF3Hs Contributes to Drought Tolerance in Soybean

Flavonoids are central to abiotic stress responses, yet the specific signaling roles and evolutionary dynamics of flavonoid biosynthetic intermediates in crop drought adaptation remain elusive. Here, we demonstrate that dihydrokaempferol (DHK) and dihydroquercetin (DHQ), specific...

A cross-sectional study on identification and prevalence of hard ticks parasitizing large and small domestic animals

Ticks are blood-sucking ectoparasites transmitting pathogens that cause anemia, skin damage, weight loss, reduced meat and milk production, morbidity, and mortality in livestock. This study identified tick species and their prevalence on buffaloes, sheep, cows, and goats in Multa...
