Molecules from the surface of any samples are removed (sputtered) through the process of ToF-SIMS which involves the use of a pulsed primary ion beam. The mass of the sputtered secondary ions is determined by means of a time-of-flight mass analyzer.
Proteins are composed primarily of long chains of much smaller units known as amino acids. There are more than 20 known amino acids that can combine to form a larger protein, and they interact with and bind with one another in ways that influence the protein’s final structure.
Most of the essential components in an HVAC system, such as cooling water pumps, fan coil units, air handling units, and water chiller, use valves to control the flow of gas, air, and water. Some of the most common control valves that you may see in an HVAC system are as follows:
PROVIDENCE, R.I. [Brown University] -- Tree-like branching structures are everywhere in the human body, from the bronchial system in the lungs to the spidering capillaries that supply blood to the extremities. Researchers have long worked to understand the cellular signaling needed to build these in...
The nitrogens are the point. The squares are the frames that carry them. These molecules are called azetidines, and they can be used as building blocks in drug design.
HOUSTON - (Aug. 5, 2019) - Laboratories use surfactants to separate things, and fluorescent dyes to see things. Rice University chemists have combined the two to simplify life for scientists everywhere.
Entanglement is one of the main principles of quantum mechanics. Physicists from Professor Johannes Fink's research group at the Institute of Science and Technology Austria (IST Austria) have found a way to use a mechanical oscillator to produce entangled radiation. This method, which the authors pu...
When you peer into the night sky, much of what you see is plasma, a soupy amalgam of ultra-hot atomic particles. Studying plasma in the stars and various forms in outer space requires a telescope, but scientists can recreate it in the laboratory to examine it more closely.
Researchers from NYU Abu Dhabi's (NYUAD) chemistry program and colleagues from the University's biology program have developed and studied the biological activity of five new, metal-organic hybrid knotted molecules, termed metal-organic trefoil knots (M-TKs). These molecules can effectively deliver ...
New study is first to show how two types of sand can behave like light and heavy liquids, shedding light on geological processes from mudslides to volcanos
An MIT research team that has already conquered the problem of getting ketchup out of its bottle has now tackled a new category of consumer and manufacturing woe
