Sentences with phrase «create hydrogen bonds»

Previously, researchers assumed that positively charged hydrogen could only create hydrogen bonds with negatively charged elements like oxygen, fluorine and nitrogen.

Their composition is largely dependent on hydrogen atoms in the molecules, and the ability of these to create hydrogen bonds with other elements.

First, the water molecules around the hydroxide ion bounced around, positioning and creating hydrogen bonds with the hydroxide.

Not exact matches

Rather, they assembled a variety of different polymer building blocks that carried different chemical functions, such as having an acidic appendage, an alkaline sidearm, or being able to create a network of weakly interacting hydrogen bonds.

These elements helped to carry out CH - activation, i.e. to break the bond between carbon and hydrogen in molecules and to create a new carbon - carbon bond and thereby obtain new promising substances.

First, they occurred quickly and the resulting nucleotides spontaneously paired with each other in water, forming hydrogen bonds like the Watson - Crick base pairs that create the «ladder - rung» pattern inside RNA and DNA helixes.

«The key is to tune the shape of the template to create a subtle bias towards the targeted carbon hydrogen bond,» said Yu.

Among the areas of research that inspire Dr. Cui are: the development of new technologies to further the development of electric transportation; creating new battery chemistry for grid - scale storage at ultra-low cost; and harnessing low - cost technologies for the development of catalysts for efficient carbon dioxide reduction and conversion into highly valuable products and inert carbon - hydrogen bond activation.

This particular discovery originated in prior work at Rochester that demonstrated quantum dots could be excellent catalysts for creating hydrogen - hydrogen bonds for solar fuel applications.

In the most common motif, created about 57 % of the time, hydroxide's oxygen atoms bonded with the hydrogen atoms on 4 water molecules while the hydroxide's hydrogen bonded to the oxygen atom on another water molecule.

A lot of the properties of water rely on creating and breaking these hydrogen bonds and a certain rate, time and energy.

Integral to the polymer's design are electron - withdrawing fluorine atoms that create sites on the polymer with more positive hydrogen atoms leading to stronger hydrogen - bonding interactions and more sensitive sensors.

Oils react under pressure with hydrogen gas that is added so that all the double bonds in the oil are saturated with hydrogen, to create a spreadable product.

This is then neutralised when it grabs a hydrogen ion from the silicon in a triethylsilane molecule, producing a safer carbon - hydrogen bond and creating a fresh molecule of silylium to attack more C - F bonds.
