Waiting is the hardest part. Especially in the case of testing for water or food contamination, which can take days or even a week in some cases for the results, leaving the possibility that people have been unknowingly exposed.
Polymers are essential in modern food packaging thanks to their low cost, light weight, flexibility, and chemical stability. They provide a crucial barrier to protect food from moisture, oxygen, sunlight, and microorganisms ...
A research team has developed upconversion nanoparticles to assist in powering molecular motors. The nanoparticles can convert near-infrared radiation, which is capable of penetrating bulk material, into blue or UV light ...
Researchers can use a metric called the particle number concentration (PNC) to calculate the number of particles in a sample, such as the number of marbles in a jar.
A typical morning hair-care routine can expose you to as much immediate nanoparticle pollution as standing in dense highway traffic, report Purdue University engineers.
For decades, researchers around the world have searched for alternatives to iridium, an extremely rare, incredibly expensive metal used in the production of clean hydrogen fuels.
Using machine learning, MIT chemical engineers have created a computational model that can predict how well any given molecule will dissolve in an organic solvent—a key step in the synthesis of nearly any pharmaceutical. ...
The trouble with many drugs is that they go where they shouldn't, producing unwanted side effects. Psychiatric drugs might cause dissociation, painkillers can induce nausea and chemotherapy often damages healthy cells. Now ...
Biomedical engineers at Duke University have developed a method to more precisely heat up gold nanoparticles to target and destroy cancerous tumors. Using imaging methods that combine light and sound to peer deeper into tissue, ...
Heat waves are becoming more common, severe and long-lasting. These prolonged periods of hot weather are especially dangerous in already hot places like Texas. In 2023, more than 300 people in Texas died from heat, according ...
