Researchers from Indian Institute of Technology Bombay, Mumbai have observed a new phenomenon in a semiconductor quantum dot-- particles of nanometre (a billionth of a meter) size which are also called artificial atoms) made of Cu2ZnSnS4 (CZTS). By shining Ultra Violet (UV) light, on the quantum dots immersed in an electrolyte, they noticed an increase in its capacitance. The effect could be engineered to serve as photocapacitors- capacitors that are charged using light.
Researchers categorized the microplastics found in Mumbai's mangroves to estimate the extent of the pollution from these tiny threats in the ecosystem.
