Influence of aging conditions on textural properties of water-glass-based silica aerogels prepared at ambient pressure
(Springer US, 2010-06-04)
The experimental results of aging time and temperature on the textural properties of water-glass (sodium
silicate)-based silica aerogels are reported and discussed. Aging of the hydrogel for different times and temperatures
led ...
Release Kinetic Models of Vanillin and Physicomechanical Properties of Thermoplastic Starch and Chitosan Nanocomposite Films: Effects of Mixing Order
(Springer Nature Switzerland AG., 2020-02-20)
The effects of mixing sequence of starch–chitosan nanocomposite films on antimicrobial properties of vanillin, the release kinetics of vanillin, and physicomechanical changes of films have been reported. Four types of films ...
A review on strategies to optimize metabolic stages of anaerobic digestion of municipal solid wastes towards enhanced resources recovery
(BioMed Central Ltd, 2019-12-17)
Recently, there are increased efforts by municipals and researchers to investigate the potential of utilizing municipal solid wastes (MSW) for resources recovery. In many parts of developing countries, MSW is mostly collected ...
Suitability of selected vegetable tannins traditionally used in leather making in Tanzania

(Elsevier Ltd., 2020-04-18)
Chrome tanning remains the most favourite technology in the leather industry worldwide due to its ability to produce leather with attributes desirable for high-quality leather such as excellent hydrothermal stability, ...
Approaches to the mitigation of ammonia inhibition during anaerobic digestion – a review
(IWA Publishing, 2020-06-03)
The digestion process of organic waste rich in high ammonia content has always been a gridlock during methanogenesis process. The free ammonia may increase inhibition/toxicity, which in turn affects the microbial community ...
Fish bladder-based activated carbon/Co3O4/TiO2 composite electrodes for supercapacitors
(Elsevier B.V., 2019-06-15)
Cobalt oxide/titanium dioxide/activated carbon (Co3O4/TiO2/Ac) composite was synthesized using simple sol-gel method before annealing at 300 °C. Fish bladder derived porous carbon used for the composite was synthesized by ...
Meticulous Overview on the Controlled Release Fertilizers
