Extraction and Characterization of Cellulose Nanocrystals from Tea Leaf Waste Fibers
The aim was to explore the utilization of tea leaf waste fibers (TLWF) as a source for the production of cellulose nanocrystals (CNC). TLWF was first treated with alkaline, followed by bleaching before being hydrolyzed with concentrated sulfuric acid. The materials attained after each step of chemical treatments were characterized and their chemical compositions were studied. The structure anal...
متن کاملSynthesis and characterization of the electrospun fibers prepared from waste polymeric materials
Recently, the demands for the production of many different types of plastic wastes are greatly growing that subsequently, lead to the serious challenges in environmental considerations. Since, these materials are rarely resolved by microorganisms, hence, their recycling to the useful materials is crucial. In the present study, we used a solution electrospinning technique to synthesize nano/micr...
متن کاملPreparation and Characterization of Cellulose Nanocrystals from Bamboo Pulp
Cellulose nanocrystals (CNCs) can be obtained from bamboo pulp by hydrolysis with sulfuric acid. Firstly, the authors conducted a series of experiments under different conditions, and concluded that the optimal parameters were as follows: sulfuric acid concentration 60%, temperature 45 °C, the time is 90 minutes and the solid-liquid ratio is 1:8. Then, transmission electron microscopy (TEM), Fo...
متن کاملIsolation and characterization of cellulose nanocrystals from garlic skin
For the value-added utilization of underutilized agricultural by-products, garlic skin obtained abundantly in the food processing industry has been tested as a new source of cellulosic materials. Cellulose microfibers (CMF) and cellulose nanocrystals (CNC) were isolated from garlic skin fibers by alkali treatment and acid hydrolysis. The crude fiber, CMF, and CNC of garlic skin were characteriz...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
