Pathological crystal structures [PDF]

open access: yesActa Crystallographica Section C Structural Chemistry, 2023
Recent decades have seen enormous changes in the technology of crystal structure analysis, but the interpretation of these data still depends on human judgment, and errors are far from uncommon. Although analysing the crystallographic results with available software tools can catch many types of errors, others can be detected only by combining ...

Tunability of wire-grid metamaterial immersed into nematic liquid crystal [PDF]

open access: yes, 2007
We propose electrically tunable hybrid metamaterial consisting of special wire grid immersed into nematic liquid crystal. The plasma-like permittivity of the structure can be substantially varied due to switching of the liquid crystal alignment by ...
