(Phys.org)—Scientists have used sunlight to turn seawater (H2O) into hydrogen peroxide (H2O2), which can then be used in fuel cells to generate electricity. It is the first photocatalytic method of H2O2 production that achieves ...

(Phys.org)—Computers are often described with "ones and zeros," referring to their binary nature: each memory element stores data in two states. But there is no fundamental reason why there should be just two. In a new study, ...

(Phys.org)—Scientists have proposed an experiment that could measure the value of Newton's gravitational constant, G, from deep space instead of an Earth-based laboratory. The researchers predict that the deep space experiment ...

(Phys.org)—One of the biggest problems plaguing high-energy, lithium-metal batteries is dendrites, which form when some of the lithium from the electrode begins to branch outside the electrode and into the electrolyte, causing ...

(Phys.org)—As its name suggests, a heat engine converts heat into mechanical energy that can be used to do work—for example, to power a car. Heat engines can operate either in a steady state (where heat is constantly being ...

(Phys.org)—The question of why space is three-dimensional (3D) and not some other number of dimensions has puzzled philosophers and scientists since ancient Greece. Space-time overall is four-dimensional, or (3 + 1)-dimensional, ...

(Phys.org)—Researchers have developed the first imaging technique that can clearly see inside molecular structures, and have used it to create 3D holograms of the atomic arrangements inside these structures. Before now, reliable ...

(Phys.org)—It might be said that the most difficult part of building a quantum computer is not figuring out how to make it compute, but rather finding a way to deal with all of the errors that it inevitably makes. Errors ...

(Phys.org)—For the past 17 years, spiro-OMeTAD, has been keeping a secret. Despite intense research efforts, its performance as the most commonly used hole-transporting material in perovskite and dye-sensitized solar cells ...

(Phys.org)—Many insects, birds, fish, and amphibians emit light as a way to communicate with each other, but the species that produces light most efficiently is the firefly. In a new study, researchers have investigated the ...

(Phys.org)—Scientists have found that an intricately beautiful yet poorly understood type of crystal found in soap bubbles follows the same mathematical rules as a much better understood type of crystal called martensite. ...

The world's oceans contain an enormous amount of energy in the form of waves, and researchers are trying to harness that energy for human use. However, most wave power stations today are still in the early stages of development, ...

(Phys.org)—Researchers have fabricated a smart skin that is self-powered by its frictional contact with the objects that it touches. When a honeybee crawls across the smart skin, the skin not only senses the insect, it also ...

(Phys.org)—For the past 100 years, physicists have been studying the weird features of quantum physics, and now they're trying to put these features to good use. One prominent example is that quantum superposition (also known ...

(Phys.org)—A new study shows that a swarm of hundreds of thousands of tiny microbots, each smaller than the width of a human hair, can be deployed into industrial wastewater to absorb and remove toxic heavy metals. The researchers ...
