The production of chemicals accounts for 40% of all energy currently used in manufacturing, and the process also results in toxic solvent waste that pollutes the environment and poses health risks to ...
MIT undergraduates are learning about nanoscale science and engineering from individual atoms up to full-scale functional systems, and they’re doing it hands-on at MIT.nano.
If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the m...
A chemistry collaboration led to a creative way to put carbon dioxide to good – and even healthy – use: by incorporating it, via electrosynthesis, into a series of organic molecules that are vital to ...
Zeolites are a class of minerals used in everything from industrial catalysts and chemical filters to laundry detergents and cat litter. They are mostly composed of silicon and aluminum — two abundant...
Chemical engineers and materials scientists are constantly looking for the next revolutionary material, chemical, and drug. The rise of machine-learning approaches is expediting the discovery process,...
Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons, or PAHs. Since the 1980s, evidence has indicated that these molecules are abund...
At any moment in the human body, in about 30 trillion cells, DNA is being "read" into molecules of messenger RNA, or mRNA, the intermediary step between DNA and proteins, in a process called transcrip...
