The Pressure-Temperature Phase Diagram of Metacetamol and Its Comparison to the Phase Diagram of Paracetamol.

Understanding the polymorphic behavior of active pharmaceutical ingredients is important for formulation purposes and regulatory reasons. Metacetamol is an isomer of paracetamol and it similarly exhibits polymorphism. In the present article, it has been found that one of the polymorphs of metacetamol is only stable under increased pressure, which has led to the conclusion that metacetamol like ...

Phase diagram of antiferromagnetic CrFe in the pressure-temperature plane

2014 The phase diagram under pressure up to 4 kbar of an alloy containing 2.8 at % Fe in chromium has been determined by neutron diffraction. A hysteretic first order transition to a commensurate spin density wave phase, together with an apparently second order transition from the disordered paramagnetic phase to an incommensurate phase, is observed. No triple point could be found and there is ...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.

Temperature-pressure phase diagram of deuterated tetramethylammonium tetrachlorozincate

2014 The pressure temperature phase diagram has been obtained in the deuterated TMATC-Zn by measuring the modulation wave vector in the range 0 to 1.8 kbar and 2014 5 to 36 °C. This diagram is a nice illustration of the devil’s staircase. It exhibits various commensurate stairs with k = 1/3,2/5 in the ferroelectric phase, 3/7 and 1/2. At high temperatures lock-in occurs at 2/5. This phase separ...
