Scientists discover transparent, high-performance LED displays

The finding opens the door to the practical application of monolayer materials, such as MoS2, in devices like LEDs and high-performance transistors. “One could develop high-performance LED displays that are transparent when powered off and flexible using the ‘perfect’ optoelectronic monolayers produced in this study,” the researchers said. Monolayer semiconductors have generated a great deal of buzz as they hold ... Read More »

Safety in numbers: Cracking the coefficient code

Decimal expansion of numbers was a common exercise in middle-school mathematics. Fractions like 1/5 and 1/4 were less taxing. Their decimal expansions terminated promptly at 0.2 and 0.25 respectively. But the fraction 1/3 was a little intriguing. Its decimal expansion did not terminate, but it soon became clear that a single digit, namely 3, started to repeat itself. For certain ... Read More »

New camera can measure greenhouse gases

Researchers have developed a new camera that can photograph and film methane in the air. It can be an important part of the efforts to measure and monitor greenhouse gases, according to researchers from Linkoping University and Stockholm University in Sweden. “The camera is very sensitive, which means that the methane is both visible and measurable close to ground level, ...

These are the best photos of Pluto you may see in decades: NASA

NASA’s New Horizons spacecraft has sent back the sharpest images of Pluto yet. According to NASA, these are the best close-up photos of Pluto that people may see for decades to come. The New Horizons spacecraft, no bigger than a piano, transmits data stored on its digital recorder each week from its flight through the Pluto System. These latest pictures ... Read More »

Researchers create new phase of Carbon, which is harder than diamonds

Q-carbon a new phase of solid carbon, created by researchers at the North Carolina State University, is harder than diamonds. Until now, diamonds have been considered the hardest naturally occurring material, but the discovery of the Q-Carbon heralds several new possibilities. “We’ve now created a third solid phase of carbon,” says Jay Narayan, the John C. Fan Distinguished Chair Professor of ... Read More »

NASA: Supply shipment takes off for International Space Station

A US shipment of much-needed groceries and other astronaut supplies rocketed toward the International Space Station for the first time in months Sunday, reigniting NASA’s commercial delivery service. If the Orbital ATK capsule arrives at the space station Wednesday as planned, it will represent the first US delivery since spring. “Santa is on his way!” Tory Bruno, president of rocket ...

Nano talk: liquid fuel gets an efficiency shot

Most of the engines today use liquid fuel to produce energy. Internal combustion engines in automobile industry, aero propulsion engines, and those used in the power generation industry, all of them use some sort of liquid fuel. The efficiency of liquid fuels cannot be increased by using the existing technologies. But given the ever-increasing demand for energy in the developing ... Read More »

NASA plans to exit space station in order to explore deeper space

As all good things must come to an end, NASA’s long space ride with the International Space Station (ISS) in low-Earth orbit will also touch the finish line in a decade from now. The US space agency will move up to the cislunar space — the area of space surrounding the moon — for an ambitious human exploration programme. William ... Read More »

NASA releases new close up of Pluto, now in colour

NASA has released an enhanced colour mosaic that combines some of the sharpest views of Pluto which the US space agency’s New Horizons spacecraft obtained during its historic flyby of the icy-dwarf planet. The pictures are part of a sequence taken near New Horizons’ closest approach to Pluto on July 14 this year, with resolutions of about 77-85 metres per ... Read More »

NISAR mission biggest collaboration of ISRO and NASA

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission will be the biggest collaboration between the two space agencies yet, said a senior scientist from NASA on Monday. The mission involves building a 2,600 kg satellite that will “effectively make a time-lapse movie of the earth” while keeping a close eye on disturbances in the ecosystem, ice-sheet collapses and natural hazards. “In ...
