Preparation and Characterization of Nanocrystalline Cellulose using Ultrasonication Combined with a Microwave-assisted Pretreatment Process
This study focuses on the extraction of nanocrystalline cellulose ( NCC) from the dried stalk of Corchorus olitorius, commonly known as jute, using a combination of a microwave-assisted alkaline peroxide pulping process (AHP) and ultrasonication. Dried jute stalk powder was pretreated using sodium hydroxide under microwave irradiation for the removal of lignin. The partially delignified sample ...
متن کاملMild steel surface pretreatment using phosphoric acid-inhibitor solution
In this study, a new mild steel surface pretreatment solution is introduced based on phosphoric acid containing a benzimidazole derivative as inhibitor. In this way, three different benzimidazole derivatives namely benzimidazole BI, 2-methyl benzimidazole 2MBI and 2-aminobenzimidazole 2ABI were studied in the 1M H3PO4 using DC and AC electrochemical techniques. Results revealed the better corro...
متن کاملA Novel Approach for Direct Preparation of Hydroxyapatite Nanoparticles from natural source using Microwave
Hydroxyapatite (HA) is one of the most common biocompatible ceramic with wide usages in various aspects of medicine due to the resemblance to the mineral bone tissue. The particle size of HA has a key roll in determination of the reaction rate at the interface of natural bones/artificial. Accordingly, this paper tries to propose a novel approach for the preparation of HA nanoparticles from natu...
متن کاملLime pretreatment of switchgrass at mild temperatures for ethanol production.
To improve the enzymatic digestibility of switchgrass at mild temperatures, lime pretreatment of switchgrass was explored at 50 and 21 degrees Celsius, and compared with that at 121 degrees Celsius. The effects of residence time, lime loading, and biomass washing on the sugar production efficiency were investigated. Pretreatments were evaluated based on the yields of biomass-derived sugars in t...
متن کاملchemical recycling of polycarbonate waste using conventional heating and microwave assisted method
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
