Insulin-like growth factor (IGF) is a hormone that greatly influences growth in fetuses and children, but also body maintenance and metabolism in adults. IGF regulates cell proliferation, differentiation, and survival by ...
When manufacturing techniques turn metals, ceramics or composites into a technologically useful form, understanding the mechanism of the phase transformation process is essential to shape the behavior of those high-performance ...
Researchers at the University of Wisconsin–Madison have described the way an enzyme and proteins interact to maintain the protective caps, called telomeres, at the end of chromosomes, a new insight into how a human cell ...
Graphene scientists from The University of Manchester have created a novel "nano-petri dish" using two-dimensional (2D) materials to create a new method of observing how atoms move in liquid.
For decades, a textbook process known as "Ostwald ripening," named for the Nobel Prize-winning chemist Wilhelm Ostwald, has guided the design of new materials including nanoparticles—tiny materials so small they are invisible ...
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.
Solid-liquid-gas reactions are common in various natural phenomenon and industrial applications, such as hydrogen-oxygen fuel cell reactions, heterogeneous catalysis and metal corrosion in ambient environments. However, the ...
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 ...
Evidence suggests that carbon nanotubes, tiny tubes consisting of pure carbon, could be forged in the envelopes of dust and gas surrounding dying stars. The findings propose a simple, yet elegant mechanism for the formation ...
As electronic, thermoelectric and computer technologies have been miniaturized to nanometer scale, engineers have faced a challenge studying fundamental properties of the materials involved; in many cases, targets are too ...
