Crystallization is a common chemical process Josh Doctson Redskins Jersey , many industrial products such as inorganic fertilizer, soda ash, chemical reagents, rubber, rubber, polymers and plastics, vitamins Troy Apke Redskins Jersey , construction materials, explosives manufacturing, and the crystallization process is a very close relationship. As typical chemical process unit operations, crystal has the following advantages:

① energy consumption. Most compounds is an exothermic crystallization process, and distillation, drying, energy consumption compared to large unit operations Geron Christian Redskins Jersey , distillation crystalline phase transition potential is only 13 to 17, only energy intensive separation RUN 10 ~ 30%.

② apply to azeotrope separation of complex systems and so on. Since nearly 90% of the organic compounds for the eutectic-type system, using ordinary distillation methods can not achieve their goals. Use of extraction, azeotropic distillation although other methods can be separated in theory, but the operation by the extraction solvent selection, the actual conditions in the difficult objective to achieve complete separation; Moreover, the extraction agents of other components of the introduction of extended process line Preston Smith Redskins Jersey , to increase investment and operating costs, and inevitably affect the quality of the final product. And distillation, extraction compared to the crystallization process does not introduce other substances, the high selectivity of the crystallization operation, can be prepared from high purity or ultra-pure products (≥ 99. 9% pure products chromatography).

③ Crystal operating temperature lower, the small degree of corrosion of equipment.

④ improve the operating environment, reduce environmental pollution. Solution crystallization process by changing the operating conditions or the addition of seed material to make the system critical components of solubility (or super saturation) changes Brandon Scherff Redskins Jersey , the system changes from the steady-state non-equilibrium steady state, so that a new phase generated to achieve the crystalline material and system, other mixtures separation.

With the development of biotechnology, protein drugs continue to emerge such as biological macromolecules, their unique features more and more attention. As we all know, depends primarily on molecular features of its unique three-dimensional structure. Therefore, to understand the function of determining that a biological macromolecules Montae Nicholson Redskins Jersey , we must examine and determine its three-dimensional structure.

On the other hand, understanding the structure of biological macromolecules for drug design, molecular structure and to change or modification of a specific application features are of great importance. X-ray diffraction to determine molecular three-dimensional crystal structure of the most reliable method, but so far for X-ray diffraction of protein crystals of biological macromolecules in this area was still one of the main technical bottlenecks, severely restricting the protein engineering, rational drug Design, synthesis and design of new vaccine development of biotechnology. Protein crystallization is a complex physical and chemical processes Samaje Perine Redskins Jersey , than the crystallization of small molecule compounds, much more difficult, mainly because of its molecular weight and molecular conformation of complex, static characteristics, physical and chemical properties of the instability itself with cofactor, ligand, and other special factors Fabian Moreau Redskins Jersey , many of the protein crystallization process is easy to lose in the activity of protein crystal growth so that the work difficult.

Often get the following results: amorphous precipitation, a large number of ceramics, twinning, multiple crystal fusion of body, or defective single crystals. Therefore, in general terms, the current biological macromolecules such as protein crystal growth is still groping and empirical Ryan Anderson Redskins Jersey , to some extent also on the opportunity.

Crystal growth has become the obstacle to the advancement speed of the crystal structure analysis of the key issues.

Liverpool manager Brendan Rodgers believes Mario Balotelli has the experience required to lead the line when they return to Champions League action for the first time in five years at Anfield on Tuesday.

Italy striker Balotelli is likely to be the senior striker in a Liverpool side, with Daniel Sturridge set to be sidelined for at least another fortnight with a thigh strain.

Balotelli, a ￡16 million ($26 million) signing from AC Milan, is one of the Liverpool players with the most European experience ahead of their Group B opener against Bulgarian champions Ludogorets Razgrad.

The 24-year-old has failed to score in his first two Liverpool appearances but Tuesday's tie could present the ideal opportunity for the Manchester City striker to get his Anfield career up and running.

"Time will tell. The boy is only just in the door," Rodgers said Monday.

"The best players enjoy that responsibility and I am sure it is one he is relishing but on the training field he is going to work hard to accept that responsibility knowing he has been brought in here to do a job which is to create and score goals and work hard.

"He was unfortunate he was ill last week and it was only on the morning of the game (Saturday's Premier League defeat by Aston Villa) he declared himself fit to play, which shows he really wanted to get out and play here.

"He is also experienced as well. He is arguably one of the most experienced players we have in terms of this competition and international calibre and at club level.
