Improvement in Properties by Copolymerization Methods-Engineering Polymer/Vinylpolymer

Improvement of cellulolytic properties of Clostridium cellulolyticum by metabolic engineering.

Cellulolytic clostridia have evolved to catabolize lignocellulosic materials at a seasonal biorhythm, so their biotechnological exploitation requires genetic improvements. As high carbon flux leads to pyruvate accumulation, which is responsible for the cessation of growth of Clostridium cellulolyticum, this accumulation is decreased by heterologous expression of pyruvate decarboxylase and alcoh...

Block and Graft Copolymerization by Controlled/Living Radical Polymerization Methods

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

C-terminus engineering of soybean proglycinin: improvement of emulsifying properties.

Introduction of the extension region of beta-conglycinin alpha' subunit at the C-terminus of proglycinin A1aB1b results in the improvement of its emulsifying properties. To understand the basic for such improvement, we introduced the alpha' and alpha extension regions to the A2B1a C-terminus, and the alpha extension and A5A4B3 hypervariable regions, and an oligopeptide composed of 20 negatively...

improvement of thermal stability of dfpase by in silico methods

efficiency of enzymes which are used in industrial or environmental applications is highly dependent on their thermal stability. in this study, the stability of dfpase has been evaluated after introducing disulfide bonds to the structure. the results obtained from a series of protein design software were subjected to molecular dynamics simulation at different temperature to test the performance...
