Ever wondered how those temperature scanners that we see everyday from malls to hospitals, actually work? These devices employ infrared technology -- the long wavelength part of light, which we cannot see with bare eyes. Atoms are always moving and their speed determines the temperature of an object. These moving atoms emit radiation not as a visible light but as heat and for most everyday temperatures, these emitted wavelengths are quite long.
A proposed method to capture carbon dioxide and convert it to industrially useful chemicals gets IIT Bombay entry to the X-prize carbon removal grand prize competition.
A porous liquid composite can convert adsorbed carbon dioxide from industrial effluents to calcium carbonate
Globally, carbon dioxide emissions from human and industrial activities are rising alarmingly, and the gas is escaping into the atmosphere. Industries use physical and chemical absorption methods to capture carbon dioxide from industrial emissions. However, these methods can only capture and store carbon dioxide, which must be transported to a permanent storage site, which requires spending energy additionally.
