Results and discussion The diffraction was almost invisible under any writing conditions after irradiation, while the sample was annealed at the liquid crystal temperature of 150°C. The grating was ...

The crystallization problem is an outstanding challenge in the chemistry of porous covalent organic frameworks (COFs). Their structural characterization has been limited to modeling and solutions ...

Srinivasarao described the self-aligning of liquid crystals Sept 14 at the 232nd national meeting of the American Chemical Society in San Francisco. His presentation was part of the session ...

Lithography brings liquid crystals into line 17 Jun 2002 US scientists could have the answer to the long-standing problem of molecular alignment in liquid crystals. Cast your mind back a couple of ...

Without X-ray diffraction, we’d never have worked out the structure of DNA. It’s also my favourite prize because it’s a beautiful mixture of fundamental scientific principles, bringing in ...
