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.
In the heart of Central India lies the Panna Tiger Reserve, a sanctuary that has seen a remarkable revival of its tiger population thanks to reintroduction efforts. But how are these majestic creatures adapting to their new environment? A team of researchers from the Wildlife Institute of India (WII) Dehradun is trying to find out.
