30-Apr-2019 NEW TECHNIQUE COULD ENABLE COLOR TUNING OF LED BULBS Read More A new technique the result of an international collaboration of scientists from Lehigh University, West Chester University, Osaka University and the University of Amsterdam could pave the way for colour tuning of a light bulb. According to Volkmar Dierolf, Distinguished Professor and Chair of Lehigh's Department of Physics, who worked on the project says, "This work could make it possible to tune between bright white and more comfortable warmer colors in commercial LEDs." The team demonstrated the possibility of color tuning Gallium Nitride (GaN)-based GaN LEDs simply by changing the time sequence at which the operation current is provided to the device. Light-emitting diodes or LEDs are semiconductor devices that emit light when an electric current is passed through it. The work is described in an article published online in ACS Photonics called "Color-Tunablility in GaN LEDs Based on Atomic Emission Manipulation under Current Injection. "In today's active LED displays, different colors are produced by three to four individual LEDs that are placed close to each other and create the different fundamental colors needed to produce the full color spectrum.
30-Apr-2019 ISRAEL HONOURS 1971 WAR HERO LT GEN JFR JACOB WITH A PLAQUE ON AMMUNITION HILL WALL OF HONOUR Read More Israel on 30th April honoured Lt. Gen. (retd) Jack Farj Rafael (JFR) Jacob, who negotiated the historic surrender of Pakistani troops in Dhaka after the 1971 Bangladesh's liberation war, with a plaque on the Wall of Honour at the Ammunition Hill here. Lt. Gen. Jacob, who died in 2016 at the age of 92, was one of the most prominent members of India's relatively small Jewish community, serving as a Lieutenant General in the Indian Army and later as a Governor of two Indian states-Goa and Punjab. The Wall of Honour at the Ammunition Hill pays tributes to the heroism and courage of Jewish soldiers who fought in the defence of their countries they lived in "implementing values of bravery, loyalty, commitment and dedication to a mission, leadership, creativity, camaraderie and sanctity of life". The Wall has plaques honouring more than 340 people comprising privates, high ranking army officers, women, front line fighters and humble members of supporting units who embodied these virtues", a senior official at the Ammunition Hill told PTI.
