The new superlattices — called monolayer atomic crystal molecular superlattices — feature a molecular layer that becomes the second «sheet» that is held in place by van der Waals forces —
weak electrostatic forces that keep otherwise neutral molecules attached to each other.
The polymer and the agent form hydrogen bonds,
weak electrostatic connections between polymer's hydrogen and an agent's oxygen atom.
This suggests to the researchers that the first step in these reactions is dominated by
weak electrostatic interactions between the reactants.
By applying DC and AC biases between the AFM probe and sample surface, DREEM can detect very
weak electrostatic interaction differences when it scans over protein versus DNA regions.
Not exact matches
Intramolecular forces, which are still
electrostatic, but because they do contain a full charge (that +1 for protons size, -1 for electrons mentioned above) but only partial charges they are considerably
weaker.
But these structures are unstable because
electrostatic forces are
weak compared with the covalent bonds formed between atoms that share electrons.
