Scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have devised an ultra-thin invisibility “skin” cloak that can conform to the shape of an object and conceal it from detection with visible light.
Working with brick-like blocks of gold nanoantennas, the Berkeley researchers fashioned a “skin cloak” barely 80 nanometers in thickness, that was wrapped around a three-dimensional object about the size of a few biological cells and arbitrarily shaped with multiple bumps and dents.
Although this cloak is only microscopic in size, the principles behind the technology should enable it to be scaled-up to conceal macroscopic items as well.
PM Modi launched IPDS scheme to strengthen power distribution
Prime Minister Narendra Modi launched the Rs. 45,000-crore Integrated Power Development Scheme (IPDS) which will strengthen distribution networks and ensure 24X7 power supply to all by 2022.
The IPDS will cover works relating to strengthening sub-transmission and distribution system, including provisioning of solar panels, metering of distribution transformers/feeders/consumer in urban areas and IT enablement of distribution sector.
