Antioxidant activity of PLA/PCL films loaded with thymol and/or carvacrol using scCO2 for active food packaging
(Food Packaging and Shelf Life, 2020)
Present study was aimed to produce biodegradable films with antioxidant activity for active food packaging. Films of poly(lactic acid) (PLA) with 5 wt% of poly(ε-caprolactone) (PCL), denoted as PLA-5, were loaded with ...
Continuous biodiesel production under subcritical condition of methanol - Design of pilot plant and packed bed reactor with MnCO3/Na-silicate catalyst
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
The continuous biodiesel production from soybean oil was carried out under the subcritical condition of methanol with MnCO3/Na-silicate as a heterogeneous catalyst. The transesterification rate was first investigated in a ...
Antibacterial ability of immobilized silver nanoparticles in agar-agar films co-doped with magnesium ions
(Elsevier Sci Ltd, Oxford, 2019)
The antibacterial ability of in situ prepared nanometer-sized silver particles, immobilized in agar-agar films, was studied as a function of the concentration of co-dopant, magnesium ions. Content of inorganic components ...
Sorption properties of TEMPO-oxidized natural and man-made cellulose fibers
(Elsevier Sci Ltd, Oxford, 2009)
Cotton and lyocell fibers were oxidized with sodium hypochlorite and catalytic amount of sodium bromide and 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO), under various conditions. Water-insoluble fractions, collected ...

(Elsevier Sci Ltd, Oxford, 2017)
Sustainable development as a concept that aims to enhance the quality of life without affecting environment has been in focus in European policies since the last decade of 20th century. The objectives of EU Sustainable ...
Process and techno-economic analysis of green diesel production from waste vegetable oil and the comparison with ester type biodiesel production
(Elsevier Sci Ltd, Oxford, 2016)
Like ester type biodiesel fuel, green diesel is a next generation transportation fuel emerging due to the need for a renewable replacement of internal combustion engine fuel, which is also fully compatible with existing ...
Visible-light active mesoporous, nanocrystalline N,S-doped and co-doped titania photocatalysts synthesized by non-hydrolytic sol-gel route
(Elsevier Sci Ltd, Oxford, 2016)
Visible-light active mesoporous N,S-doped and co-doped anatase TiO2 powders were synthesized by non-hydrolytic sol-gel route, starting from TiCl4 and Ti((OPr)-Pr-i)(4) dissolved in cyclohexane or dimethyl sulfoxide, later ...
