MIT engineers designed a pill that can report when it has been swallowed, an advance that could aid in medication adherence.
To ensure that the tissue structures of biological samples are easily recognisable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is uranyl acetate. However, some laboratories are not allowed to use this highly toxic and radioactive substance for safety reasons. A research team at the Institute of Electron Microscopy and Nanoanalysis (FELMI-ZFE) at Graz University of Technology (TU Graz) has now found an environmentally friendly alternative: ordinary espresso. Images of the samples treated with it were of equally good quality as images of comparative samples, which were prepared with uranyl acetate. The researchers have published their findings in the journal Methods.
In the International Journal of Extreme Manufacturing, researchers use a nickel–titanium shape memory alloy shaped through laser powder bed fusion (LPBF) to create tiny and wavy structural features only 0.3 millimeters across, much smaller and more controlled than what is typically possible in metal metamaterials.
This review article systematically summarizes research progress on pressurized oxy-fuel combustion system designs, heat transfer mechanisms, combustion behavior, and pollutant emissions.
A research team led by Dr. Shin Hur at the Korea Institute of Machinery and Materials (KIMM, President Seog-Hyeon Ryu), including Syed Turab Haider Zaidi, a student researcher from the UST–KIMM School at KIMM, in collaboration with Dr. Byung-Chul Lee’s team at the Korea Institute of Science and Technology (KIST), has developed the world’s first skin-attachable, noninvasive blood pressure sensor using PMN-PT single-crystal piezoelectric composites integrated through a low-temperature soldering process.
