Researchers have successfully increased the lifespan and stability of solid-state lithium-ion batteries, creating a viable approach for future widespread usage. The strength of the new, high-density batteries produced by the University of Surrey means that they are less likely to short-circuit – a problem found in previous lithium-ion solid-state batteries. […]
University of Queensland scientists have cracked a problem that’s frustrated chemists and physicists for years, potentially leading to a new age of powerful, efficient, and environmentally friendly technologies. Using quantum mechanics, Professor Ben Powell from UQ’s School of Mathematics and Physics has discovered a ‘recipe’ which allows molecular switches to work at […]
Holes help make sponges and English muffins useful (and, in the case of the latter, delicious). Without holes, they wouldn’t be flexible enough to bend into small crevices, or to sop up the perfect amount of jam and butter. In a new study, University of Chicago scientists find that holes can also […]
In 2010, a research team led by Professor Zhong Lin Wang at Georgia Institute of Technology, USA, showed that the use of piezoelectric materials (materials that generate electrical energy on applying mechanical strain) could improve the performance of optoelectronic devices – devices that convert light into electricity (e.g. solar cells) or electricity into light […]
Nuclear is also much more expensive, according to the WNISR report. The cost of generating solar energy is between $ 36 and $ 44 per megawatt-hour (MWh), according to the WNISR, the amount of onshore wind energy is between $ 29-56 per MWh. Nuclear power costs between $ 112 and $ 189. Is nuclear safer […]
What he does with Joe Biden as a man, a public figure or a high-ranking official, his president is unlike any other in modern American history. He may have faced more problems at the same time than any other president since Franklin D. Roosevelt, and one indication that Biden has already applied for a Security […]
