hydrated form of theophylline-7-acetic acid obtained by recrystallization from water. In particular this study is aimed towards the characterization of the new form as well as providing information on its physical stability and dehydration kinetics

petrography are also recognized, due to the recrystallization of the studied sample inherited from mylonitization, which is probably ubiquitous in the study area. Geologic background MZ (Ófalu Group) The MZ is a

as the result of the melting of crystals of higher stability and perfection, grown during the heating run as a consequence of recrystallization or reorganization of crystals initially formed during isothermal crystallization. Finally, in the case of

structure of honey can change, the mobility of ions and charged groups can increase causing a decrease of electrical impedance of honey. The recrystallization of honey, the recovery to the original state presumably takes a relatively long time – some weeks

successively recrystallizes into stable form II crystals; this phenomenon, called beta-recrystallization, is characterized by the (exothermic) peak numbered 3 in Fig. 5 [ 13 ]. The last (endothermic) peak (numbered 4 in Fig. 5 ) corresponds to the melting of

Abstract  

Cyclo-tetraphosphates of the type Zn2−x−yCaxCoyP4O12 were synthesized by thermal decomposition and recrystallization of polyphosphate glasses, i.e. mixed higher linear phosphates.
