Process Efficiency in Wellness Sector

open access: yesUshus - Journal of Business Management, 2005
The 'Wellness Sector' is an emerging sector in India. This concept is catching up the world over as this sector focuses on the maintenance of health rather than cure. The trauma involved in cure, high escalating costs and the shrinking size of families makes Wellness a better option than cure. India is known amongst westerners for its ancient ...

Engineered ultraviolet InGaN/AlGaN multiple-quantum-well structures for maximizing cathodoluminescence efficiency

open access: yesAIP Advances, 2022
We demonstrate a systematic way to understand and select the accelerating voltage for maximizing cathodoluminescence (CL) by correlating the carrier diffusion length with the efficiency of ultraviolet (UV) InGaN/AlGaN multiple quantum wells (MQWs).
