전체 글 (151) 썸네일형 리스트형 A high-yield method for nano-particle clusters 읽자 A team of researchers from China, the U.S. and Canada has developed a high-yield method for assembling targeted nanoparticle clusters. Over the past several decades, scientists have learned how to create nanoparticles—particles of matter that are between 1 and 100 nanometers in diameter—for a wide variety of purposes. They are currently created using one of several techniques. The most popular a.. using ML to investigate cellular mechanism in infected cell Using an artificial intelligence (AI) cell classification technique, Northwestern Medicine investigators found that viruses can control structural and genetic polarity inside the cell nucleus. The findings, published in Nature, highlight the importance of genome organization during infection and the extent to which AI can help scientists identify complex intracellular processes. Viruses can cont.. Eliminating dissolution of platinum in fuel cell - 읽어보기 PEMFCs rely on hydrogen as a fuel, which is oxidized on the cell's anode side through a hydrogen oxidation reaction, while oxygen from the air is used for an oxygen reduction reaction (ORR) at the cathode. Through these processes, fuel cells produce electricity to power electric motors in vehicles and other applications, emitting water as the only by-product. Platinum-based, nano-sized particles.. review: flexible piezoelectric energy harvesters for implantable sensor Wearable and implantable devices are currently used for a variety of functions, including health tracking and monitoring. However, supplying energy usually requires cumbersome batteries and downtime due to recharging. Now, an international team of researchers suggests that advances in materials and electronic design may be able to convert biomechanical energy into electric energy, paving the way.. using robot to automate the COVID detection process An Imperial team has repurposed robotic technology normally used for synthetic biology research to help with testing for COVID-19. Researchers at Imperial were able to repurpose an existing high-throughput robotic platform as a way to help NHS diagnostic labs avoid these bottlenecks—cutting their reliance on reagents in high demand from other testing platforms around the country, which were in v.. Acoustic tweezers - 논문 읽고 리뷰하자 Acoustic tweezers are a powerful, versatile set of tools that use sound waves to manipulate bioparticles ranging from nanometer-sized extracellular vesicles to millimeter-sized multicellular organisms. Over the past several decades, the capabilities of acoustic tweezers have expanded from simplistic particle trapping to the precise rotation and translation of cells and organisms in three dimensi.. Discovery of RNA on surface membrane (maxRNA) - 논문 읽어보자 Bioengineers at UC San Diego have shown that human-genome produced RNA is present on the surface of human cells, suggesting a more expanded role for RNA in cell-to-cell and cell-to-environment interactions than previously thought. This new type of membrane-associated extracellular RNA (maxRNA) is found in human cells that are not undergoing cell death, shedding light on the contribution of nucle.. Role of cholesterol in membrane "Cholesterol is known to promote tighter molecular packing in cell membranes, but reports about how it stiffens membranes have been so conflicting," said Ashkar, who is a faculty member in the Virginia Tech College of Science. "In this work, we show that, at the nanoscale level, cholesterol indeed causes membrane stiffening, as predicted by physical laws. These findings affect our understanding .. 이전 1 2 3 4 5 6 7 8 ··· 19 다음
