FEMALE STUDENT: How can liquid exist below freezing? Why doesn't it freeze?MALE PROFESSOR: Well… when water becomes ice, the molecules bond together and they get sort of, uh, locked into place. They can't move around as much anymore. So each molecule is surrounded by other molecules...

1. Water is actually quite simple, but the way how the water molecule is formed gives water its unique properties.2. Water is a liquid at room temperature and has a relatively high frozen point.3. The nutrients in whatever falling into the ocean will quickly become available to other ...
The OH (O - H) group on the molecule is what makes it an alcohol. There are four types of bonds in this molecule: carbon-carbon (C - C) carbon-hydrogen (C - H) carbon-oxygen (C - O) oxygen-hydrogen (O - H) The chemical bonds between the atoms are shared pairs of electrons....
Liquid-to-solid phase transition of oskar ribonucleoprotein granules is essential for their function in Drosophila embryonic development. Cell https://doi.org/10.1016/j.cell.2022.02.022 (2022). This study shows that the regulation of osk RNP physical properties are important for asymmetric expression...
"Sandwich" immu- nosensors waste time and energy compared to the "label-free" type, in which the electrochemical signal molecule is immobilized on the electrode or dissolved in an electrolyte in only one step to detect the target7,8. Therefore, it is more desirable to construct "label-...
Water molecules cling to cellulose and climb along it through a process called capillary action — cellulose can even defy gravity in order to pull the water along its surface. Because water is a polar molecule, meaning one side of it holds a more positive charge and the other end a more ...
At a given temperature, the pressure exerted by a gas that is in equilibrium with a solid or liquid is called vapor pressure. It is also a measure of the substance to transform into its gaseous phase. In general, the vapor pressure increases as the tem...
The mechanism for the formation of the M +· ion of α‐tocopherol, a viscous oily material, under fast atom bombardment (FAB) conditions without a liquid matrix was investigated by using positive‐ and/or negative‐ion electron impact, gas‐phase FAB, gas‐phase fast molecule bombardment and...
a member of the gupta research group, wondered if the process known as diffusiophoresis plays a role in nature's pattern formation. diffusiophoresis happens when a molecule moves through liquid in response to changes, such as differen...
