Early detection makes batteries safer

TU Darmstadt and MIT develop methods for monitoring with machine learning

05-Nov-2024 - The safe use of lithium-ion batteries, such as those used in electric vehicles and stationary energy storage systems, critically depends on condition monitoring and early fault detection. Failures in individual battery cells can lead to serious issues, including fires. To mitigate these risks, ...

Bubble findings could unlock better electrode and electrolyzer designs

A new study of bubbles on electrode surfaces could help improve the efficiency of electrochemical processes that produce fuels, chemicals, and materials

14-Oct-2024 - Industrial electrochemical processes that use electrodes to produce fuels and chemical products are hampered by the formation of bubbles that block parts of the electrode surface, reducing the area available for the active reaction. Such blockage reduces the performance of the electrodes by ...

A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine

MIT engineers have developed a fast and sustainable method for producing hydrogen fuel using aluminum, saltwater, and coffee grounds

01-Aug-2024 - A sustainable source for clean energy may lie in old soda cans and seawater. MIT engineers have found that when the aluminum in soda cans is exposed in its pure form and mixed with seawater, the solution bubbles up and naturally produces hydrogen — a gas that can be subsequently used to power an ...

Researchers develop a detector for continuously monitoring toxic gases

The material could be made as a thin coating to analyze air quality in industrial or home settings over time

22-May-2024 - Most systems used to detect toxic gases in industrial or domestic settings can be used only once, or at best a few times. Now, researchers at MIT have developed a detector that could provide continuous monitoring for the presence of these gases, at low cost. The new system combines two existing ...

A new sensor detects harmful “forever chemicals” in drinking water

A user-friendly system could offer a cheap, fast way to test for PFAS

14-Mar-2024 - MIT chemists have designed a sensor that detects tiny quantities of perfluoroalkyl and polyfluoroalkyl substances (PFAS) — chemicals found in food packaging, nonstick cookware, and many other consumer products. These compounds, also known as “forever chemicals” because they do not break down ...

Researchers 3D print components for a portable mass spectrometer

Lightweight and inexpensive, miniaturized mass filters are a key step toward portable mass spectrometers that could identify unknown chemicals in remote settings

08-Jan-2024 - Mass spectrometers, devices that identify chemical substances, are widely used in applications like crime scene analysis, toxicology testing, and geological surveying. But these machines are bulky, expensive, and easy to damage, which limits where they can be effectively deployed. Using additive ...

Microbes could help reduce the need for chemical fertilizers

A coating protects nitrogen-fixing bacteria: Start-up to commercialise coated bacteria for large-scale use in regenerative agriculture

21-Nov-2023 - Production of chemical fertilizers accounts for about 1.5 percent of the world’s greenhouse gas emissions. MIT chemists hope to help reduce that carbon footprint by replacing some chemical fertilizer with a more sustainable source — bacteria. Bacteria that can convert nitrogen gas to ammonia ...

Detection of per- and polyfluoroalkyl substances (PFAS) by interrupted energy transfer

02-Nov-2023 - PFAS, a family of highly fluorinated substances, represent a danger for humans and the environment. Particularly problematic members of this family, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) appear to cause organ damage and cancer, as well as disrupting the ...
