New design in thermoelectric devices can increase both output power and efficiency
A significant problem in electronic devices is the generation of heat during their operation. This phenomenon not only leads to the wastage of electric power but can also damage the device. Thermoelectric materials, which convert heat to electricity and vice versa, can be used to turn the generated heat back into electricity, thereby saving power and avoiding overheating of the device.
Shape of dried paint or ink deposit is related to the concentration and size of particles in these colloids
Ever wondered why we use only specific inks for the inkjet printer? Why not any random dye? The wrong ink may result in non-uniform and patchy printing. Printing inks are colloids—tiny solid particles suspended in a liquid. The size and the concentration of the solid particles in the ink specified for printers are designed to deposit uniformly on paper.
Prof Raghavan B Sunoj of the Department of Chemistry of the Indian Institute of Technology Bombay has received the 2019 Shanti Swarup Bhatnagar Prize by Council of Scientific and Industrial Research (CSIR). The prize recognizes his outstanding contributions for providing molecular level insights on organic reaction mechanisms.
