A groundbreaking study by researchers from Chongqing University and the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, reveals that diatoms can transform lunar soil, boosting its water retention and nutrient levels to support robust plant growth. This breakthrough paves the way for sustainable agriculture in lunar habitats, offering a vital step toward humanity’s long-term survival and interplanetary exploration.
The innovation proposes converting cellulose acetate from cigarette butts into carbon-based low-dimensional functional materials, extending their high-value applications in renewable energy fields such as triboelectric nanogenerators, flexible batteries, and hydrogen storage devices. This waste-to-resource approach simultaneously addresses environmental pollution and reduces material costs for clean energy technologies.
A novel in-plane pore engineering strategy to enhance the hydrogen evolution reaction (HER) performance of Ti₃C₂Tₓ MXene is demonstrated, achieving higher electrochemical activity, lower charge transfer resistance, and improved stability, while further boosting performance via localized surface plasmon resonance under near-infrared laser irradiation.
Researchers from Donghua University have developed a novel piezo-photocatalytic technology using bismuth ferrite (Bi2Fe4O9) to efficiently degrade reactive dyes in wastewater. The study demonstrates that combining piezoelectric and photocatalytic effects significantly enhances the degradation efficiency of the dye KN-R. This innovative approach not only offers an effective solution for treating dye wastewater but also highlights the potential of Bi2Fe4O9 as a sustainable and eco-friendly material for environmental applications.
The protective effectiveness of environmental barrier coatings (EBCs) for SiC-based composites is challenged by the thickening and phase transformation of the SiO2 scale, known as thermally grown oxide (TGO). In this study, a tri-layered TGOs scale, comprising cristobalite, Hf-doped SiO2 glass, and particle-reinforced Hf-Si-O glass, was formed during the oxidation of MoSi2/HfO2 duplex EBCs. The incorporation of the gradient Hf-doping and HfO2/HfSiO4 particle-reinforcement were demonstrated to effectively suppress the crystallization and phase transition of the SiO2 and mitigate internal stress within the EBCs, generating a crack-blocking effect. This effect prevented the TGOs scale from further channel crack propagation, enabled the SiC substrate with no detectable corrosion after 200 h of exposure at 1500 °C in steam, even when the TGOs thickness reached 24.5 μm. This work presents a novel strategy to simultaneously extend the service lifetime and enhance the high-temperature capability of EBCs through the tailored design of TGOs composition and structure.
This research article focuses on the taxonomic contributions of Pleosporales and Kirschsteiniotheliales from the Xizang Autonomous Region, China. The study identifies ten new taxa of microfungi, including a new genus and nine new species, based on morphological and phylogenetic analyses.
