Purification of Erythromycin by Antisolvent Crystallization or Azeotropic Evaporative Crystallization
Crystallization plays an important role in separation and purification of the antibiotics. And it is also an indispensable step in preparation of pharmaceuticals with biological activities and specific crystal form. As the last step in purification, crystallization determines the puri‐ ty, crystal habit, granularity and its distribution as well as pharmacologic effect, biologic ac‐ tivity and p...
متن کاملRapid crystallization of L-arginine acetate on engineered surfaces using metal-assisted and microwave-accelerated evaporative crystallization().
We report the application of our newly described crystallization technique, which employs silver island films (SIFs) and microwave heating, to rapid crystallization of L-arginine acetate (LAA). Using our technique, LAA crystals (~ 1.2 mm in length) were grown from a 20 μl solution in 1 min on surface functionalized SIFs. In control experiments (glass slides and at room temperature) the growth o...
متن کاملMorphological Control of Polymer Spherulites via Manipulating Radial Lamellar Organization upon Evaporative Crystallization: A Mini Review
Various spherulites or spherulitic crystals are widely encountered in polymeric materials when crystallized from viscous melts or concentrated solutions. However, the microstructures and growth processes are quite complicated and remain unclear and, thus, the formation mechanisms are rather elusive. Here, diverse kinds of spherulitic growths and patterns of typical polyesters via evaporative cr...
متن کاملMorphological Classification of Galaxies into Spirals and Non-spirals
The aim of this master's thesis is the classification of images of galaxies according to their morphological features using computer vision and artificial intelligence techniques. We deal specifically with the shape of the galaxy in this project. The galaxies are broadly categorized into 3 categories according to their shape: circular, elliptical and spiral. Out of these 3 possible shapes, corr...
متن کاملSound Spirals
Sound Spirals are part of an ongoing project attempting to interpret sound in a physical medium: sculpturally, mathematically, and irreversibly. They demonstrate different processes for creating data visualisations of recorded audio in the form of 3D printed sculptural art using open source programming tools and audio software (Processing and Audacity) and contemporary 3D printers including the...
