ELECTROMETALLURGY has at last succeeded in producing metallic calcium in commercial quantities, and at what must be considered a relatively low price. Until within a few weeks ago this metal had ...

A team of scientists led by the Begum Rokeya University in Bangladesh designed a solar cell with an absorber based on inorganic calcium nitrogen iodide (Ca3NI3) perovskite.. The research group ...

The calcium, which is harmless to consume, proceeds through. Once the calcium phosphate is used up, dissolved lead in the water reacts with the potassium iodide, causing the water to turn yellow.

WHILE carrying out investigations in a number of aqueous solutions of electrolytes, we have observed the interesting feature of a decrease of ultrasonic velocity with increase of concentration in ...

Iodide perovskites such as methylammonium lead iodide (CH3NH3PbI3) can convert sunlight to electricity. Researchers use a decades-old geometric 'tolerance factor' to propose new combinations of ...

Together, DDAB, oleate and calcium, form globules, called vesicles, with intriguing life-like movement. The vesicles crawl around on a glass slide by reacting with iodide ions, ...
