PII: S1461-5347(98)00063-7 ▼ Interest in the development of implantable polymeric drug delivery systems capable of modulating drug release as a function of specific time-varying therapeutic requirements dates back to the 1980s.There is currently a new generation of potent drugs emerging as a result of recent advance...

CRYSTALLIZATION BEHAVIOUR OF GELS AND GEL-MONOLITHS IN THE Na2O-B2O3-SiO2 SYSTEM

Additive controlled crystallization

Additives play a decisive role in crystallization processes. We survey the ongoing efforts in the realm of additive-controlled crystallization. Emphasis is placed on the commonly used and most studied types of additives and their influences on prenucleation, stabilization of amorphous precursors, nucleation, crystallization, chiral resolution, nanocrystal assembly, polymorph, and thus morpholog...

Controlled Crystallization of LTA Zeolitic Nanoparticles from a Clear Solution Using Organic Template

LTA Zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. The as-synthesized LTA zeolite particles were characterized by powder X-ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Fourier Transform InfraRed (FT-IR) spectroscopy, </e...

the pathology of historical texts translation: a study of persian translations of 7th volume of cambridge history of iran

ترجمه با گسترش زبان آغاز شده و اهمیت آن روز به روز افزایش می یابد، و برای اولین بار به عنوان شاخه ای از دانش و روشی برای انتقال علوم، فرهنگ و تجربه در در دوره قاجار در ایران آغاز شد. در حقیقت متون تاریخی از اولین متونی هستند که در ایران ترجمه شدند چرا که به سیاستمداران آن دوره کمک می کردند تا به علل موفقیت جهان غرب و پیشرفت هایشان در طول تاریخ پی ببرند، بنابراین به تدریج ترجمه این گونه متون رون...
