In brief Researchers have developed a method by which artificial crystal lattices with a large lattice constant can be created in a semiconductor material. The large lattice constant leads to a ...

A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The ...

I've always been fascinated by how materials break down, especially glasses and polymers that don't have a regular crystal ...

a. Schematic diagram of aggregate structure in NaCl crystal. b. Schematic diagram of chemical structure in zwitterionic aggregate. c. Visualization of the inter- and intramolecular motion in ...

Slow light in square-lattice chalcogenide photonic-crystal (PC) holey fibers with uniform longitude geometry are proposed and theoretically investigated. By using the planewave-expansion method, a ...

Learn about changes of state from melting, evaporating and boiling with this interactive activity designed for the GCSE AQA chemistry specification.

By trapping both products in the crystal lattice, we now have a complete resolution profile of all the catalytic steps. One crystal structure refined to 1.55 Å resolution shows two states of the ...

The recent discovery that a beam of charged particles can pass through a crystal lattice in certain directions with surprising case is examined for its theoretical and practical implications ...

The efficacy of methylxanthine derivatives in poly (hydroxyalkanoate) (PHA) nucleation correlates to the presence or absence of a hydrogen bond-donating imide nitrogen along specific crystal surface ...

In optical coherence tomography (OCT) system, high numerical aperture (NA) PCF is required for collecting back scattering light for detailed information from body tissue. In this paper, we propose a ...
