MIT researchers have developed an approach called SEPSTAT, for solid-phase extraction, preservation, storage, transportation, and analysis of trace contaminants. The method is based on a small, user-friendly device the team developed, which absorbs trace contaminants in water and preserves them in a dry state so the samples can be easily dropped in the mail and shipped to a laboratory for further analysis.
Researchers have demonstrated a new method for testing microscopic aeronautical materials at ultra-high temperatures. By combining electron microscopy and laser heating, scientists can evaluate these materials much more quickly and inexpensively than with traditional testing.
Purdue University researchers developed a device to decrease energy consumption of the vapor-compression heat pump cycle, which is commonly used in homes, businesses and vehicles for cooling and heating. The team created a novel turbomachine expander that helps harvest previously wasted energy used in the process of moving the air from high to low pressure. The device can be used as a control agent within an existing heat pump.
Researchers have developed the first decentralized algorithm with a collision-free, deadlock-free guarantee and validated it on a swarm of 100 autonomous robots in the lab.
Dr. Hun-Gi Jung and his research team at the Center for Energy Storage Research of the Korea Institute of Science and Technology have announced the development of silicon anode materials that can increase battery capacity four-fold in comparison to graphite anode materials and enable rapid charging to more than 80% capacity in only five minutes. When applied to batteries for electric vehicles, the new materials are expected to more than double their driving range.
A catalyst is needed for a chemical process that releases hydrogen from an H2O molecule. It can be made, for example, from platinum, or from molybdenum. But these are quite expensive materials. Therefore, the output energy is expensive too.
New machine learning method from Stanford, with Toyota and MIT researchers, has slashed battery testing times -- a key barrier to longer-lasting, faster-charging batteries for electric vehicles -- by nearly fifteenfold.
Avoiding unnecessary bleeding during neuroendoscopic surgeries is crucial. When blood vessel location in a tumor cannot be visually confirmed, unintentional damage to the vessel and subsequent bleeding may occur. We propose a method for tumor blood vessel detection using a surgical robot system equipped with a force sensor in the gripper. Using this method, pulsation of a simulated artery inside a simulated tumor was detected by the force sensor, displayed as a gripping force wave.
Greater use of electric vehicles might be good for the environment, but further growth hinges on continued availability of critical battery components such as cobalt. Cell phones and other electronics also depend on the element's availability. Supplies of the metal are adequate in the short term, but shortages could develop down the road if refining and recycling aren't ramped up or made more efficient, according to research published in ACS' Environmental Science & Technology.
University of Washington researchers have developed a mathematical model that describes how rotating detonation engines work.
