Researchers from the group of Prof. Jia Shuang at Peking University and the group of Prof. Xu Gang at Huazhong University of Science and Technology have recently collaborated to investigate the heavy-fermion ferromagnet CeCrGe3. They observed giant anomalous Hall and anomalous Nernst effects and revealed that these remarkable responses originate from Kondo-driven topological flat bands. The results were published under the title “Giant Anomalous Hall and Nernst Effects in a Heavy Fermion Ferromagnet” in Science Bulletin.
By imaging the superfluid density and superconducting transition temperature in an infinite-layer superconductor, researchers revealed a strong correlation between the two quantities. This correlation is quantitatively similar to that reported in cuprate superconductors, hinting at a close connection between the superconductivity of infinite-layer nickelates and that of cuprates.
A transcriptomic analysis-based study reports altered gene expression in KRAS-overexpressing human microvascular endothelial cells (HMEC-1), highlighting it as a key driver for brain arteriovenous malformation (bAVM), a rare vascular disorder. 4,737 differentially expressed genes in KRAS-overexpressing HMEC-1 cells were identified, enriched in pathways related to cell adhesion, signaling, transport, and mitochondrial function. The results indicate that KRAS-driven molecular alterations may play a role in the development of bAVM.
The discovery of pathogenic genes based on large CHD cohort forms the foundation for improving early diagnosis, prevention, control, and treatment of CHD. To this end, Academician Lin He launched the Chinese Children's CHD Genome Research Project. The research team conducted whole-genome sequencing on 354 core CHD families from China, integrated single-cell transcriptomic data and phenotypic analysis in model animals, and identified high-confidence CHD risk genes. This study has constructed the largest genetic etiology map of congenital heart disease in Asian populations.
In a recent study of Amazonian forests, researchers from the South China Botanical Garden (SCBG) of the Chinese Academy of Sciences, in collaboration with Cornell University and several international research institutions, found that the residence time of carbon in Amazonian vegetation will continue to shorten as atmospheric drying intensifies and convective storm activity increases, thereby undermining the forests’ long-term carbon storage capacity.
Aqueous zinc-ion batteries (AZIBs) have emerged as promising candidates for large-scale energy storage systems in the post-lithium era, owing to their inherent safety and cost-effectiveness. However, their practical implementation faces significant challenges, including chemical corrosion, uncontrolled dendrite formation, and hydrogen evolution reactions (HER). To address these limitations, an innovative “hydrophobic-zincophilic” Pd/g-C3N4 composite coating was developed for Zn anodes by atomic-layer-deposition (ALD). The g-C3N4 matrix serves as an ion flux regulator, while uniformly dispersed Pd nanoparticles function as zincophilic nucleation sites, enabling homogeneous Zn deposition. In situ optical characterization demonstrates the coating’s dual functionality: the hydrophobic component effectively minimizes water contact, while the zincophilic phase guides ordered Zn plating, jointly suppressing parasitic reactions. The modified Pd/g-C3N4@Zn anode achieves exceptional cycling stability (> 2500 h) and maintains a remarkable Coulombic efficiency of 99.56% over 5000 cycles at 2 A/g, representing a significant advancement in AZIB anode engineering. This work provides a generalizable interfacial design strategy for developing high-performance AZIB systems.
Efficient overall water splitting (OWS) technology has been highly demanded across the world, of which the key is the development of active and stable electrocatalysts for both hydrogen and oxygen evolution reactions (HER/OER). Herein, novel crystalline Ni3S2 nanorods tuned by low-crystalline NiCoSx (NiCoSx@Ni3S2) are synthesized via an ion-exchange strategy. The built-in electric field at the heterogeneous interface driven by work function difference, facilitates rapid electron transfer from Ni3S2 to NiCoSx via a robust Ni–S–Co bond bridge. This synergistic combination of the conductive crystalline core and low-crystalline shell optimizes the d-band center, balancing intermediate adsorption/desorption, speeding up water dissociation, enhancing hydrogen adsorption/desorption for HER, and lowering the energy barrier for OER, ultimately boosting OWS efficiency. The defect-rich, low-crystalline NiCoSx shell, bonded to the crystalline core via Ni–S–Co bonds, serves as a protective armor, enabling dynamic reconstruction into NiCoOOH and suppresses sulfide leaching, ensuring catalytic stability. The optimized NiCoSx@Ni3S2 achieves low HER/OER overpotentials of 346/520 mV@1000 mA cm−2, evidenced by an ultralow cell voltage of 2.10 V@1000 mA cm−2 for OWS and long-term durability up to 400 h. The work paves a novel way to fabricate sulfur-based electrocatalysts with high yet balanced activity and stability for OWS via an interface engineering strategy.
The utilization of solar energy to address energy and environmental challenges has a seen a significant growth in recent years. Metal halides, which offer unique advantages such as tunable bandgaps, high light absorption efficiencies, favorable product release rates, and low exciton binding energies, have emerged as excellent photocatalysts for energy conversion. This paper reviews the recent advancements in both all-inorganic and organic-inorganic hybrid metal halide photocatalytic materials, including the fundamental mechanisms of photocatalytic CO2 reduction, various synthesis strategies for metal halide photocatalysts, and their applications in the field of photocatalysis. Finally, it examines the current challenges associated with metal halide materials and explores potential solutions for metal halide materials, along with their future prospects in photocatalysis applications.
Gallium nitride (GaN) nanostructures are highly promising for photoelectrochemical (PEC) water splitting due to their excellent electron mobility, chemical stability, and large surface area. However, the wide bandgap (~3.4 eV) of GaN limits its ability to absorb a broad spectrum of solar radiation, restricting its PEC performance. To address this limitation, MoS2/GaN nanorods (NRs) heterostructures for enhanced PEC applications were fabricated on thin tungsten foil using a combination of atmospheric pressure chemical vapor deposition (CVD) and laser molecular beam epitaxy (LMBE). The Raman spectroscopy and X-ray diffraction revealed the hexagonal phase of GaN and MoS2. X-ray photoelectron spectroscopy examined the electronic states of the GaN and MoS2. PEC measurements revealed that the MoS2-decorated GaN NRs exhibited a photocurrent density of approximately172 μA/cm2, nearly 2.5-fold compared to bare GaN NRs (~70 μA/cm2). The increased photocurrent density is ascribed to the Type II band alignment between MoS2 and GaN, which promotes effective charge separation, the decrease in charge transfer resistance, and the increase in active sites. The findings of this work underscore that the CVD and LMBE technique fabricated MoS2/GaN heterostructures on W metal foil substrate can provide the vital strategy to raise the PEC efficiency toward solar water splitting.
