High performance green barriers based on nanocelluloseAbstract
With the increasing environmental concerns such as sustainability and end-of-life disposal challenges, materials derived from renewable resources such as nanocellulose have been strongly advocated as potential replacements for packaging materials. Nanocellulose can be extracted from various plant resources through mechanical and chemical ways. Na... ...

Valorisation of food waste to biofuel: current trends and technological challenges
Tập 2 - Trang 1-4 - 2014
Demand for biofuels is rapidly growing worldwide as petroleum based fuels are finite reserves. In this context, biodiesel and bioethanol are popular biofuels that are commercially available in various countries. Biofuels can be prepared from edible biomass. However, this is already generating food versus fuel debate among the members of civil societies. Therefore, there are needs to synthesize bio......
The use of combination of zeolites to pursue integrated refined pyrolysis oil from kraft lignin
- 2014
A mixture of Y and M type zeolites were applied to pyrolyze kraft softwood (SW) lignin with the objective of studying the combination effect of different types of zeolite on pyrolysis. The chemical structures of the subsequent pyrolysis oils were examined. Nuclear Magnetic Resonance (NMR) spectroscopy including 13C, 31P of phosphitylated bio-oils, Heteronuclear Single-Quantum Correlation (HSQC)-NM......
Tối ưu hóa sản xuất L-asparaginase bởi Serratia marcescens (NCIM 2919) dưới quá trình lên men rắn sử dụng bã dầu dừa Dịch bởi AI
Tập 1 - Trang 1-8 - 2013
Nghiên cứu hiện tại tập trung vào việc sử dụng các sản phẩm phụ từ rác thải nông nghiệp được tạo ra từ nhà máy dầu để sản xuất enzyme L-asparaginase bằng cách sử dụng Serratia marcescens dưới điều kiện lên men rắn. Các phương pháp cổ điển và thống kê được áp dụng để tối ưu hóa các biến quá trình và kết quả được so sánh. Phương pháp cổ điển một yếu tố tại một thời điểm (OFAT) và phương pháp bề mặt ......

Novel perspectives for evolving enzyme cocktails for lignocellulose hydrolysis in biorefineries
Tập 1 - Trang 1-12 - 2013
The unstable and uncertain availability of petroleum sources as well as rising cost of fuels have shifted global efforts to utilize renewable resources for the production of greener energy and a replacement which can also meet the high energy demand of the world. Bioenergy routes suggest that atmospheric carbon can be cycled through biofuels in carefully designed systems for sustainability. Signif......
Study on the color levelness of silk fabric dyed with vegetable dyes
Tập 3 - Trang 1-4 - 2015
At present, customers are more conscious about the quality of clothing items. As a result, it becomes more challenging for the manufacturers to maintain the consistent dyeing quality. Unlevelness is generally unaccepted in commercial dyeing, except some cases such as stone-washed, acid-washed or pigment-dyed textiles. The aim of the study was to evaluate the color levelness quality of fabric dyed ......
Using metrics and sustainability considerations to evaluate the use of bio-based and non-renewable Brønsted acidic ionic liquids to catalyse Fischer esterification reactions
Tập 1 - Trang 1-13 - 2013
Ionic liquids have found uses in many applications, one of which is the joint solvation and catalysis of chemical transformations. Suitable Brønsted acidic ionic liquids can be formed by combining lactams with sulphonic acids. This work weighs up the relative benefits and disadvantages of applying these Brønsted acidic ionic liquid catalysts in esterifications through a series of comparisons using......
Microwave-assisted catalytic esterification of α-glucoisosaccharino-1,4-lactone with tall oil fatty acids
Tập 4 - Trang 1-5 - 2016
Carbohydrates-rich materials are partly degraded during alkaline kraft pulping into a complex mixture of aliphatic carboxylic acids consisting of α-glucoisosaccharinic acid as one of the main acids. On the other hand, crude tall oil, containing significant amounts fatty acids, is obtained as a by-product from kraft pulping. One interesting novel approach is to utilize chemically both these side-st......
