A groundbreaking study introduces a silane coupling agent strategy to enhance the performance of wide-bandgap perovskite solar cells (WBG-PSCs). By anchoring trimethoxysilane (TMOS) molecules at the perovskite/hole transport layer interface, researchers achieved a record-high open-circuit voltage (VOC) of 1.345 V and a power conversion efficiency (PCE) of 19.69% in single-junction devices. Extending this approach to all-perovskite tandem solar cells (TSCs), the team reached an impressive 28.45% PCE with exceptional stability, retaining 90% efficiency after 500 hours of operation. The work, published in a leading journal, highlights the transformative potential of interfacial engineering for next-generation photovoltaics.
Safflower is widely valued for its flavonoid glycosides, particularly for cardiovascular therapeutics and natural dyes.
In a paper published in Science Bulletin, the research team led by Professor Wen Zhang from the Department of Rheumatology and Immunology at Peking Union Medical College Hospital (PUMCH) has made significant progress in understanding the pathogenesis of IgG4-related disease (IgG4-RD). The study, for the first time, demonstrates that the overexpression of early growth response factor-1 (EGR1) in epithelial cells is a core driver promoting the characteristic tissue fibrosis of the disease, laying a scientific foundation for developing potential targeted therapies.
Garlic, a globally significant food and medicinal crop, suffers major quality loss during storage due to sprouting and decay.
A team of researchers has developed the first high-resolution genetic map and a versatile SNP chip for Panax ginseng, a tetraploid medicinal plant with complex genomic architecture.
Grafting between different plant species can offer advantages like disease resistance and structural resilience. However, graft incompatibility remains a biological mystery.
Recent research highlights that structured exercise is a powerful tool for reducing the risk of colorectal cancer. Incorporating exercise into daily routines is increasingly recognized as an effective way to strengthen the body's natural defenses and lower the risk of colorectal cancer in the long term. Early detection, however, remains the most effective way to reduce colorectal cancer mortality.
Surgery has advanced due to innovations in anesthesiology, aseptic techniques, and antibiotics. Minimally invasive techniques reduce patient trauma but increase equipment complexity and costs. Surgical robots address these challenges, improving medical efficiency. This review summarizes their evolution, clinical status, advantages, challenges, and future directions like intelligence and specialization to promote their clinical and technological development.
Chinese researchers have recently challenged the long-held belief that "all life depends on sunlight." In a study published in Science Advances, the researchers identified how microbes in deep subsurface areas can derive energy from chemical reactions driven by crustal faulting, offering critical insights into life deep below Earth's surface.
