For machines with mechanical elements, friction is an unavoidable enemy. It is a major source of service failure and can reduce the lifespan of any machinery, from bicycles and cars to airplanes and assembly lines.
The past few decades have witnessed a great amount of research in the field of two-dimensional (2D) materials. As the name implies, these thin film-like materials are composed of layers that are only a few atoms thick. Many ...
Matching particles and antiparticles are small units of matter that have the same mass but opposite electric charges. Typically, these units of matter with opposite electric charge tend to annihilate one another.
The emergence of multicellularity, requiring complex interactions between different groups of individual cells for metabolic and physiological benefits, is a great success in the history of biology. While multicellularity ...
As one of the largest-volume industrial chemical processes today, hydroformylation converts olefins, H2 and CO into aldehydes and related products more than 10 million tons annually.
Researchers from Skoltech and their colleagues in Russia and Spain have reported a proof-of-concept demonstration of a new radiation-safe method for mapping the internal structure and stress distribution in samples of materials ...
Scientists have long puzzled over the gap in the fossil record that would explain the evolution from invertebrates to vertebrates. Vertebrates, including fishes, amphibians, reptiles, birds, mammals, and humans, share unique ...
Carbon dioxide or CO2 can potentially be used as a feedstock to be converted into carbon-neutral "solar fuels" that store energy from the sun. But for them to be competitive with fossil fuels, the chemical reaction that performs ...
Results of multiple and complementary lab analyses of minerals found in samples of material from Antarctica could give scientists a better understanding of the surface and subsurface environment of Mars, and indicate locations ...
At first glance, the slightly murky waters in the tube look like a scoop of stormwater, complete with leaves, debris, and even lighter threads in the mix. But in the Petri dish, the thin vermicelli-like threads floating delicately ...
