Abstract This paper comments on a recent article “Revolutionary poetry and liquid crystal chemistry: Herman Gorter, Ada Prins the interface between literature science” by Hub Zwart (Foundations of Chemistry, published online: 10 July 2020), in which author explores influence research epic poem Pan written her long-time lover Gorter. The present reviews basic science crystals explains connection...

A detailed historical review is presented and the difficulties arising when defining such a funda mental concept as structural type in crystal chemistry are analyzed. Particular attention is paid to the genetic relationship between different structural types and to the criteria of choosing between them. Many other terms and concepts of modern crystal chemistry defined for completeness. PACS num...

ten chromite ores from ophiolite complexes in se iran were analyzed mineralogically by xrd, chemically by xrf, and mineral chemistry by epma. the identified paragenesis of silicate minerals of chromite ores with the x-ray diffraction is pronounced differently. it consists of secondary phases formed as serpentine, cr-containing chlorite (kaemmererite), chromic garnet (uarovite) with preserved pa...

sciencemag.org SCIENCE are designed to high specification to get the best possible output. That, however, can limit their integration into photonic devices and optical circuits. Bahari et al. fabricated resonant cavities of arbitrary shape within a hybrid photonic crystal structure. The confinement of light to topologically protected edge states resulted in lasing at communication wavelengths. ...

We are largely unable to predict the composition and crystal structure of new extended structure compounds. Yet we find that as materials become more complex in stoichiometry and structure, new, interesting, and perhaps useful, phenomena are encountered. The need for improved experimental and theoretical approaches to seize more rapidly the opportunities provided in this complexity is discussed.

The essay is dedicated to the relation of symmetry and asymmetry-chirality in Nature. The Introduction defines symmetry and its impact on basic definitions in science and human activities. The following section Chirality of molecules reveals breifly development of notion of chirality and its significance in living organisms and science. Homochirality is a characteristic hallmark of life and its...

Computer modelling has been used to study the design of a guest–host reflective liquid-crystal display with a phase compensator, operating at the nematic–cholesteric transition. It is shown that, by choosing the parameters of the phase plate and the step of the helix of the chiral additive, it is possible to simultaneously obtain high reflectance and image contrast and also a moderate degree of...

the safe and effective management of radioactive waste has been given utmost importance from the very inception of nuclear industry in india and it covers the entire range of activities from handling, treatment, conditioning, transport, storage and finally disposal. radioactive waste is generated at various stages of the nuclear fuel cycle, which includes the mining and milling of uranium ore, ...

influential people, I am focused in taking part in the vast frontier of the chemistry field and entering the medical field in the future. In order to achieve this goal, I have put much effort in chemistry and have also partaken in chemistry research. Under Dr. Jing Li's supervision, I am currently doing research on the synthesis and crystal growth of novel metal-based coordination compounds. Th...
