Sentences with phrase «types of chemical bond»

Using the same technique, a few years later they succeeded in distinguishing different types of chemical bond between carbon atoms in a hydrocarbon molecule.
The samples ranged from a simple alcohol to a complex plant hormone, and the new method, dubbed «CAL» for covalent alignment (the molecules form a type of chemical bond known as a covalent bond in the MOFs), enables researchers to determine the complete structure of a molecule from a single MOF crystal that contains the sample molecules in its pores.

The wavelengths of the absorbed light reveal how the target molecule's chemical bonds vibrate, which in turn tells about the types and positions of atoms in the molecule, the kinds and strength of bonds among atoms and the symmetry of the molecule, Milo says.
In a hair strand, the keratin molecules are mainly held together by two forces: chemical cross-links between cysteines (a type of amino acid) and weaker hydrogen bonds.

However, the strength of the carbon - fluorine bond makes it difficult to remove and replace fluorine atoms in a molecule, greatly limiting the structures and types of chemicals that can be made.
Materials chemists have been trying for years to make a new type of battery that can store solar or other light - sourced energy in chemical bonds rather than electrons, one that will release the energy on demand as heat instead of electricity — addressing the need for long - term, stable, efficient storage of solar power.
The high reactivity of some lysine sites also means that certain chemical compounds can make a certain type of extra-tight, effectively irreversible bond with them, known as a covalent bond.
