Robotic Suit – The Ultimate Outfit for Super-Soldier

Rex Jameson, a 5-foot-11 with 180 pounds software engineer seems just like others “Average Joe”. When he owns his free time, those extreme sports such as bike hiking, swimming, playing tennis and skies will be his favorite time killer events. Do not be fooled by his appearance, as Jameson was one of the honor software engineers, which has a contract with the U.S. Army and currently working on a top-secret project. You must be wondering, what kind is this so said “Top secret project” thing? Well, Jameson is fully responsible to research, create, and produce a “Robotic Suit” that will be widely used by the U.S. Army in the near future. “Everyday, I need to put on this 150 pounds “exoskeleton” that mostly made up of aluminium and electronics, most of the peoples gets bored on the specimen, instead of gets tired like me,” Jameson said. It’s hard to believe…

LED lamps will replace light bulbs in near future

Seems this can be true. Faiz Rahman who is a nano electronics researcher at Glazgow university states that low-energy bright LED light Bulbs are almost here. As matter of fact LEDs are very energy efficient, but fact is that about 70% of electrical energy is converted to light, and only about 20% of it getting out. The rest of light is trapped inside semiconductor due to high refractive index of LED-air surface. But as Faiz says by making LEDs to let more light out their brightness can be compared to ordinary light bulbs. How to make this happen? This can be done by making series of holes on the surface of LED. Rahman has already made several LED prototypes where holes on surface are about 200nm in diameter (400 times narrower than human hair) and 100nm deep. As LED chip is about 0.3×0.3mm there is enough space for hundreds of…
