Therefore, a new type of two-dimensional molecular crystal
was introduced due to the halogen bonds between the fluorine atoms.
The utility of such an approach in the solution of a molecular crystal
structure has already been demonstrated .
The molecular crystal
structure of capsaicin, the hot component of chilli peppers, was solved directly from synchrotron powder diffraction data alone, using the same simulated annealing procedure outlined in the previous section .
All materials, including dielectrics, semiconductors and molecular crystals
, react to such field oscillations with an intricate interplay between atomic-scale charge displacements (polarizations) and collective carrier motion on the nanometer scale (currents).
His early work as a solid-state chemist was concerned with the characterization and chemical consequences of dislocations and other structural defects in molecular crystals
, certain minerals and layered solids.
Among their topics are computer simulations of charged colloids, layer-by-layer assembly on stimuli-responsive microgels, the dynamics and structure of water nanotube clusters confined to nanoporous molecular crystals
, the quantum electrochemical study of benzene derivatives, possibilities and limitations of electrokinetic methods in biological interfaces, and surface characteristics and attachment behaviors of bacterial cells.
The first four chapters examine the interplay of charge (polarons) and neutral (excitons) photoexcitations in pi-conjugated polymers, oligomers, and molecular crystals
in the time domain of 100 fs-2 ns.
Crystals of purines are formed by molecules and classified as molecular crystals
Kitaigorodsky, Molecular Crystals
, Nauka, Moscow (1971) (in Russian).
At first, a patchwork of "nucleation islands" peppers the gold surface as molecular crystals
congeal from a gas into a solid.
of the Negev) presents a comprehensive text and sourcebook on the polymorphism of molecular crystals
for practitioners and advanced students in disciplines concerned with the organic solid state.
During the past 20 years, however, researchers have realized that when they make extremely tiny particles of metals, inert gases or molecular crystals
, the melting point drops, sometimes by a lot.
