Quantitative evaluation of sulfur-polymer matrix composite quality
(Elsevier Sci Ltd, Oxford, 2013)
In order to predict service life of the sulfur polymer composite, the samples were subjected to the induced destruction using 10% hydrochloric acid solution. Control specimens were prepared using Portland cement binder. ...
Effects of the concentrated NH4NO3 solution on mechanical properties and structure of the fly ash based geopolymers
(Elsevier Sci Ltd, Oxford, 2013)
The geopolymers based on fly ash were exposed to the concentrated (6 M) NH4NO3 solution for 540 days. The highest compressive strength decrease occurred in the initial 28 days testing period. Study of the effects of the ...
SBA-15 templated mesoporous carbons for 2,4-dichlorophenoxyacetic acid removal
(Elsevier Science Sa, Lausanne, 2013)
The ordered mesoporous silica SBA-15 was synthesized and used as a template for obtaining mesoporous carbon replicas. Adsorptive removal of pesticide 2,4-dichlorophenoxyacetic acid (2,4-D) from aqueous solutions onto two ...
Design of biocompatible immobilized Candida rugosa lipase with potential application in food industry
(Wiley-Blackwell, Hoboken, 2016)
BACKGROUNDBiocatalysts are a promising alternative for the production of natural flavor compounds. Candida rugosa lipase (CRL) is a particularly important biocatalyst owing to its remarkable efficiency in both hydrolysis ...

Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier, Amsterdam, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
Optimization of the process of Cu(II) sorption by mechanically treated Prunus persica L. - Contribution to sustainability in food processing industry
(Elsevier Sci Ltd, Oxford, 2017)
This paper presents an eco-friendly approach for minimizing heavy metal pollution, offering food waste valorization and energy source at the same time. It focuses on Cu(II) sorption by low cost sorbent developed by mechanical ...
Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, Amsterdam, 2015)
A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in ...
Industrial steel waste as an iron source to promote heterogeneous and homogeneous oxidation/reduction reactions
(Elsevier Sci Ltd, Oxford, 2019)
This work examines the mill scale (MS) of hot rolling, a waste product formed in industrial steel processing. MS was evaluated as an iron source in promoting the oxidation of Reactive Red 120 azo dye in location-sourced ...
Controlled enzymatic hydrolysis for improved exploitation of the antioxidant potential of wheat gluten
(Elsevier Science Bv, Amsterdam, 2017)
The aim of the study was to find the optimal operational and process parameters for the enzymatic hydrolysis of wheat gluten in a batch stirred bioreactor regarding both degree of hydrolysis and antioxidant capacity of the ...
