According to computational complexity theory, mathematical problems have different levels of difficulty in the context of their solvability. While a classical computer can solve some problems (P) in polynomial time—i.e., the time required for solving P is a polynomial function of the input size—it often fails to solve NP problems that scale exponentially with the problem size and thus cannot be solved in polynomial time. Classical computers based on semiconductor devices are, therefore, inadequate for solving sufficiently large NP problems. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/301PwUf

The green hydrogen economy is a sustainable alternative to fossil fuels. However, one of the challenges of constructing a global hydrogen economy is hydrogen transportation by sea. A new paper proposes solid air as a medium for recycling cold energy across the hydrogen liquefaction supply chain. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/Jh5Izwe

An international team of researchers, including nanoengineers at the University of California San Diego, has uncovered nanoscale changes inside solid-state batteries that could offer new insights into improving battery performance. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/yNLjYO2

It's estimated that mining, refining, and processing metals commonly used in construction, referred to as structural metals, contribute around three billion tons of CO2-equivalent emissions. And, although recycling these materials has the potential to mitigate their negative environmental impact, many sustain damage, like fractures, that can preclude them from extending their lifecycles. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/f6gVKGc

Maybe you can't tell a book from its cover, but according to researchers at MIT you may now be able to do the equivalent for materials of all sorts, from an airplane part to a medical implant. Their new approach allows engineers to figure out what's going on inside simply by observing properties of the material's surface. from Tech Xplore - electronic gadgets, technology advances and research news https://ift.tt/Kc9u2wn
