TL;DR: In this paper, an integrated history of hema-toxylin is presented, tracing from the height of the Mayan civilization, through the development of the baconian scientific method, during the Atlantic slave trade, and in supramolecular stereochemical associations while dyeing crystals.

TL;DR: The crystal structure of 3,4-methylenedioxymethamphetamine, also known as 'ecstasy' or MDMA, has been determined by X-ray diffraction.
Abstract: The crystal structure of 3,4-methylenedioxymethamphetamine {systematic name: N-methyl-l-[3,4-(methylenedioxy)phenyl]-2-aminopropane } hydrochloride, C 11H 15 NO2.HC1, also known as 'ecstasy' or MDMA, has been determined by X-ray diffraction.

TL;DR: In this paper, the growth of new phases as single-crystal islands within polycrystalline frag-ments that remained metastable at room temperature was studied. And they obtained by X-ray diffraction three new crystal structures of KDP that they showherein.
Abstract: respectively, have each inspired industries,much effort has been focused upon characterizing newphases. During the past 30 years, researchers havereturned time and again to the changes in the tetrago-nal form of KDP upon heating because no single studypaints a clear picture of what is happening. Whilereexamining the progression of the high-temperaturetransformations, we noticed the growth of new phasesas single-crystal islands within polycrystalline frag-ments that remained metastable at room temperature.From these phases, we obtained by X-ray diffractionthree new crystal structures of KDP that we showherein. This rich polymorphism dispels the notion
