Smart speakers that are customarily used in your living room can be programmed to act as an aid to physicians in hospital operating rooms, according to new research presented today at the Society of Interventional Radiology's 2019 Annual Scientific Meeting.
Researchers from Tokyo Metropolitan University have shown that a newly engineered catalyst made of gold nanoparticles supported on a metal oxide framework shows breakdown of ammonia impurities in air, with excellent selectivity for conversion to nitrogen gas. Importantly, it is effective at room temperature, making it suitable for everyday air purification systems. The team successfully identified the mechanism behind this behavior, paving the way towards the design of other novel catalytic materials.
Researchers from Tokyo Metropolitan University have shown that the tunable hydrophobic nature of dense siloxane gels is strongly correlated with their catalytic activity, explicitly demonstrating how molecules with different hydrophobic nature at the molecular level interact differently with surfaces of differing hydrophobicity. This is also the first time a siloxane gel has been shown to be highly effective for the reaction of silyl ethers, commonly used as a protecting agent.
Ryerson University Physicist Dr. Michael Kolios, his former graduate student Dr. Michael Moore, and collaborator zebrafish model expert Dr. Xiao-Yan Wen developed a new mode of photoacoustic imaging called F-mode. This new mode selectively enhances photoacoustic image features based on the size of the object and the sounds it produces.
Imagine smart materials that can morph from being stiff as wood to as soft as a sponge - and also change shape. Rutgers University-New Brunswick engineers have created flexible, lightweight materials with 4D printing that could lead to better shock absorption, morphing airplane or drone wings, soft robotics and tiny implantable biomedical devices. Their research is published in the journal Materials Horizons.
A new type of hydrogel material developed by Brown University researchers could soon make assembling complex microfluidic or soft robotic devices as simple as putting together a LEGO set.
Researchers from the George Washington University and the Moscow Institute of Physics and Technology have developed a solution for multiparametric optical mapping of the heart's electrical activity. This technique is a useful tool for enhancing our understanding of the mechanisms behind cardiac arrhythmias. Arrhythmia causes your heart to beat too quickly, too slowly or erratically. Hijacking the heart's vital rhythm and pumping function can have serious consequences like a stroke or cardiac arrest.
Researchers from Mount Sinai and IBM reveal that the number of mitochondria in a cell is, in great part, associated with how the cancer responds to drug therapy.
According to the US Centers for Disease Control and Prevention, about half of all Americans will have periodontal disease at some point in their lives. Characterized by inflamed gums and bone loss around teeth, the condition can cause bad breath, toothache, tender gums and, in severe cases, tooth loss. Now, in ACS Nano, researchers report development of a membrane that helps periodontal tissue regenerate when implanted into the gums of rats.
State breast density notification laws that mandate reporting of mammogram results can prompt further screening and modestly boost cancer detection rates, say researchers at Yale's School of Public Health and School of Medicine. Their study was published in the American Journal of Public Health.
