Chemists have developed a method that produces cyclic depsipeptides in a single step with high yields and in unusually large sizes, ranging up to rings with 60 atoms

Researchers disprove the idea that water degrades black phosphorus and find the material is actually hydrophobic

Diet, medications, and beauty products leave molecular traces on the objects we touch, providing an unbiased, data-driven profiling method for crime scene investigations and other potential applications

Penn findings in animal study pave way to develop new drugs for obesity-related liver disease

Findings could help to trigger new applications of drugs for diagnostics and develop new materials

Invention could dramatically reduce the number of chemicals in cleaning products and their impact on the environment

"If you want to see something that happens very, very fast, you need a tool that can measure a very, very tiny time period."

In order to uncover the structure of these proteins, researchers used a technique called protein crystallography

The new method will help break the stranglehold of carbon-hydrogen bonds present in the chemical feedstocks used to make bioactive molecules

The new material is based on polymer hollow fibers treated to retain their structure—and pore sizes—as they are converted to carbon through pyrolysis
