Study shows single atoms can make more efficient catalysts
Catalysts are chemical matchmakers: They bring other chemicals close together, increasing the chance that they’ll react with each other and produce something people want, like fuel or fertilizer.
Since some of the best catalyst materials are also quite expensive, like the platinum in a car’s catalytic converter, scientists have been looking for ways to shrink the amount they have to use.
Now scientists have their first direct, detailed look at how a single atom catalyzes a chemical reaction. The reaction is the same one that strips poisonous carbon monoxide out of car exhaust, and individual atoms of iridium did the job up to 25 times more efficiently than the iridium nanoparticles containing 50 to 100 atoms that are used today.
C. diff might not originate from external transmission but rather from within the infected patient themselves. Hospital staff dedicate significant effort to safeguard patients from infections during their hospital stay. Through practices ranging from [...]
Google says it has made a significant step in identifying disease-causing genes, which could help spot rare genetic disorders. A new model named AlphaMissense is able to confidently classify 89 per cent of all [...]
MINDWATCH study reveals cognitive peaks with everyday pleasures. Listening to music and drinking coffee are the sorts of everyday pleasures that can impact a person’s brain activity in ways that improve cognitive performance, including [...]
Moderna has developed a new and improved version of its COVID-19 vaccine. The unique formulation (mRNA-1283) reduces the vaccine's content from the full-length SARS-CoV-2 spike protein to a narrowly focused encoding of just two [...]
Breast cancer in its various forms affects more than 250,000 Americans a year. One particularly aggressive and hard-to-treat type is triple-negative breast cancer (TNBC), which lacks specific receptors targeted by existing treatments. The rapid [...]
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a process that can upcycle most plastics into chemical ingredients useful for energy storage, using light-emitting diodes (LEDs) and a commercially available catalyst, all [...]
The mere scent of seafood can severely sicken those allergic to it — and therefore they are more likely to avoid it. Similarly, individuals who experience food poisoning from a specific dish tend to [...]
Researchers in Germany and Japan have been able to increase the diffusion of magnetic whirls, so-called skyrmions, by a factor of ten. In today’s world, our lives are unimaginable without computers. Up until now, [...]
Omicron infections have a lower risk of long COVID than earlier variants, according to a study analyzing data from 11,000 participants. The risk of developing long COVID is significantly lower following an infection with [...]
Researchers have discovered that insulin resistance, typically linked with type 2 diabetes, is also present in cancer patients and can accelerate the spread of the disease. In the 1920s, scientists found that the urine [...]
Scientists from ETH Zurich and the University of Geneva have developed a new technique that allows them to observe chemical reactions taking place in liquids at extremely high temporal resolution. This innovation enables them to track how molecules [...]
Research published recently suggests that Pfizer’s erectile dysfunction drug Viagra can decrease the risk of developing Alzheimer’s disease by up to 69 percent. The research, which was published in Nature, found that the medication has [...]
An AI-powered model utilizes chest X-rays to help develop biomarkers for aging. What if determining “your age” was based on your chest rather than your face? Scientists from Osaka Metropolitan University have crafted an [...]
Cancer biomarkers circulating in body fluids can be used for diagnosis and treatment monitoring. However, current detection technology lacks the required sensitivity, limiting biomarker use in clinical applications. Colorectal cancer is the second most [...]
The findings could lead to a cure for LAM. Researchers from the University of Cincinnati may have identified a potential treatment for lymphangioleiomyomatosis (LAM), a rare lung condition resembling cancer found predominantly in women of reproductive [...]
