Color purity

The mechanoluminescence (ML) intensity increases linearly with increasing impact velocity of the moving piston, suggesting that the sintered phosphors can also be useful as a stress sensor.

The phosphors are widely used in emissive displays. However, all currently used phosphors still need considerable improvement, such as lower current saturation, higher efficiency, and better chromaticity.

Here in this paper we prepared Eu3þ doped SrAl2O4 phosphors with various concentrations of Eu3þ (1e5 mol) by a green combustion technique. The phase structure and purity of all prepared nanopowders (NPs) were studied by X-ray diffraction analysis. The prepared NPs showed a fibre-like morphology which is confirmed by scanning electron microscopy results.

Edible wax coating is one of the method for enhancing the shelf life of fruits and vegetables, thereby post-harvest losses of these can also be reduced. India ranks first in the production of rice bran oil and large amount of wax available from the oil refineries. At present Indian scenario this wax is more used in pharmaceutical and cosmetics industries even though it is edible. Lack of proper refining method constraints its use in food application.

Before the days of mass literacy, medicine was more art than science, and people recognized a pharmacy by the four traditional colored bottles that represent earth, fire, air, and water. Medicine has come a long way since the days of the apothecary with its impressive collection of powders and bottles; drugs today are highly regulated and must comply with standards set by the U.S., Europe, Japan, and other countries. A drug must be shown to be efficacious and meet rigorous standards of purity, composition, and potency before being approved for use in the patient populatio...
