What are liquid crystals? (on the 100th anniversary of the discovery)NEODYMIUM PERCHLORATE1,8-NAPHTHYRIDINE-N-MONOXIDECOMPLEX X-RAY STRUCTUREA survey is presented on the structures of all currently known crystals: thermotropic and lyotropic, low-molecular and high-molecular, colloidal, heterophase, ...
Capsaicin, also known as chili pepper extract, is an organic compound with the molecular formula C18H27NO3. It exists in peppers (Capsicum annuum) and their variants in the Solanaceae family. It crystallizes from petroleum ether as monoclinic crystals or rectangular flakes. It has maximum UV abso...

You can interpret Raman spectra to identify chemicals and get structural information. Raman scattering results from the interaction of light with molecular vibrations. These vibrations are very sensitive to changes in chemistry and structure, so you can spot subtle differences in molecular environment. G...
Nonmolecular compounds Manycompoundsdo not fit the strict definition of a molecule but are common in chemistry and everyday life. Some examples of structures that are not molecular in nature are crystals, minerals and metals. Noble gasesare elements that do not have valence electrons and, therefor...
Photonic crystals are periodic nanostructures that can selectively direct wavelengths of light in the same way as semiconductors...
Guanidine Thiocyanate is an ultrapure, molecular biology grade reagent. It is free of detectable nuclease and protease activity and is a strong protein denaturant, as both the guanidinium cation and the thiocyanate anion are chaotropic agents. It is provided in one bottle containing 500 g. It is...
What do you mean by molecular structure? Are you asking about the molecular geometry? If so, please re-submit the question and ask exactly what you want to know. The term "molecular structure" is rather ambiguous. Upvote • 0 Downvote Add comment Still...
Like humans, these microorganisms love sugar, using it as a molecular building block and energy source. As they consume it, the bacteria generate byproducts in the form of acids, such as lactic acid. Mutans streptococci are resistant to this acid, but unfortunately, our teeth aren't. While ...
What are non-crystalline solids? What is the conductivity of 0.01M KCl? What type of crystal solid has delocalized electrons? What kind of crystalline solid is graphite? What is the molecular weight of KCl? What type of solid is made up of crystals?
