(Guido Mieth/Getty Images) Ice characteristics Ice is not constantly ice all the way through. Even at temperatures level well below freezing, its surface area can be coated in a membrane of quasi-liquid atoms, with its density typically only a few nanometers. Its formation procedure is referred to as premelting (or 'surface melting'), which is why your ice...
Researchers developed a "DishBrain" system that associated neurons to a computer running the typical computer game Pong. Within five minutes, the cells commenced "learning" and improved their efficiency. The device of "learning" could entail the free-energy concept, according to which the brain searches for to lessen entropy (unpredictability) in its atmosphere. Recently research announced in...
Mixed plastics are difficult to recycle, but a new process shows how it can be done.Credit: China Photos/Getty Mixtures of plastics, normally a headache to recycle, have been broken down into helpful, smaller chemical ingredients in one two-step process, reported in Science on 13th October. The plastics problem facing the globe is exacerbated by the difficulty...
The distributions and sizes of lithium peroxide on the end surfaces of C-AAO electrodes and inside them. Credit: Prof. TAN Peng's team With a high power density, Li-O2 batteries have become a state-of-the-art battery Innovation. Inside the Li-O2 battery, the generation and disintegration of the discharged product solid lithium peroxide (Li2O2) have a significant impact...

DOI: 10.1038/s41586-022-05008-1 A team of researchers connected with several institutions in South Korea, working with two coworkers from Princeton University and one from Columbia University, has accomplished a new milestone in the development of...
Credit: CC0 Public Domain A new kind of "phase change" in water was first recommended 30 years ago in a research study by scientists from Boston University. Because the shift has been predicted to happen at supercooled problems, however, confirming its presence has been challenging. That is because, at these low temperatures, water really does...
The L3 HAPLS at ELI Beamlines Research Center in the Czech Republic. Credit: ELI Beamlines Lawrence Livermore National Laboratory (LLNL) researchers have developed a compact multi-petawatt laser that uses plasma transmission gratings to overcome the power restrictions of traditional solid-state optical gratings. The design might allow the construction of an ultrafast laser up to 1,000...
According to new research, food production is already one of the biggest stressors to our planet, but it has made substantially more challenging by the interaction of Earth system processes. Earth system procedures refer to the natural activities that maintain the planet in a habitable and also useful state. This includes procedures occurring in the...
