Explain why the exact size of an atom is difficult to determine. Why is the three-membered ring containing nitrogen called an aziridine group so reactive? Why does carbon make up all organic molecules? Why not silicon, which is also in the 4th group of the periodic table? ...
As these reactive gas or plasma components interact with the surfaces of parts in the chamber, the molecular bonds of the first 1 to 5 layers of surface molecules are broken, “activating” them. To deposit plasma carbon coating onto a component, carbon-containing feedstock is in...
Coatings also improve the chemical resistance of cutting tools, protecting them from oxidation and diffusion with reactive materials. This is especially important when machining materials like stainless steel or titanium alloys, which can cause rapid tool d...
摘要: A new electrochemical process that turns carbon dioxide into usable ethanol with tiny spikes of carbon and copper was discovered almost by accident, says Adam Rondinone, a researcher at the Oak Ridge National Laboratory and lead author of the study describing the process. 年份: 2018 收藏...
Reactive membrane, and a carbon layer on at least one is modified to yield a porous substrate, active sites were deposited on a porous substrate. And partially deoxygenated least, active site comprises a metal species that are chemically bonded to the carbon layer. Method for forming a reactive...
With the intensification of the greenhouse effect, a series of natural phenomena, such as global warming, are gradually recognized; when the ambient temperature increases to the extent that it causes heat stress in plants, agricultural production will in

CLIP is a proprietary 3D printing technology developed by Carbon. CLIP uses an oxygen-permeable window which creates a “dead zone” (a thin liquid interface) of uncured resin between the window and the object. This prevents the part from adhering to the bottom of the print basin. This ...
A pharmaceutical supply chain that's fit for purpose today and tomorrow is one that's not just reactive, but proactive. It will anticipate and accommodate current and future trends, driving forces and challenges presented by the climate crisis. Whether it be a fast-developing public health emerge...
is able to produce most of its own oil, the country still feels some of the effects through the globalized economy. Burning fossil fuels also adds carbon gasses to our atmosphere at a much greater rate than can be filtered out naturally. We’ve seen the effects through our lifetimes, with...
