These bonds between molecules, which are
called hydrogen bonds, dominate the properties of water and ice.
Water molecules in the solid state, such as in ice and snow, form weak bonds (
called hydrogen bonds) to one another.
The secret of floating ice has long been known: a phenomenon
we call hydrogen bonds.
Not exact matches
They are
called saturated because
hydrogens fill all the
bonds in the carbons, soaking the molecule in
hydrogen.
Relying on a technique
called infrared spectroscopy to explore the
bonds between atoms, the researchers noticed it attaching to positive
hydrogen atoms.
They used a star - shaped molecule
called AEEP (aminoethoxy ethanol substituted phosphazene), the arms of which act as dynamic and mobile
hydrogen bonding plasticiser molecules while being connected to a central core, effectively preventing migration and leeching of the starch molecules from the resulting plastic.
IBS scientists used a reaction based on lithium dissolved in ammonia,
called the «Birch - type reaction,» to introduce
hydrogen onto graphene through the formation of C - H
bonds.
An unsaturated fatty acid is missing
hydrogens, and as a result the carbons
bond to each other twice, forming what is
called a double
bond.
Our bodies basically don't know how to handle trans - fats as they are not truly found in nature; they are manufactured in a factory with a process
called hydrogenation, where an extra
hydrogen bond is forced into the fat molecule.
The structure of the «nanoglue» and the clay nanosheets allowed the layers to form cooperative
hydrogen bonds, which gives rise to what Kotov
called «the Velcro effect.»
