The double bond prevents the benzene group at each end from rotating around the axle linking them.
Crucially, heat and light can temporarily loosen up the bond between the nitrogen atoms, allowing them to rotate.
The team got around the problem by engineering the vaccine to have disulphide bonds cross-linking the protein triangles together.
International team seamlessly bonds CNTS and graphene September 5th, 2015phagraphene, a'relative'of graphene, discovered September 2nd, 2015chip Technology Pillared graphene gains strength:
To do so, the team applied a powerful bond-making reaction, called KAHA (alphaketoacid-hydroxylamine) ligation,
The KAHA ligation uses special types of organic molecules to form new bonds without the usual need for toxic chemical reagents.
the forces that bond the atoms together cause the atoms to vibrate and spread the energy throughout the material,
In the same vessel, they then change to a different building block, allyl glycidyl ether (AGE), an epoxide with a double bond in its side chain,
