Enzyme production by solid-state fermentation on soybean meal: A comparative study of conventional and ultrasound-assisted extraction methods
(Wiley, Hoboken, 2019)
Protease, cellulase, and alpha-amylase producing Bacillus subtilis strain was cultivated by solid-state fermentation technique using soybean meal as a substrate. The aim of the present study was to establish a highly ...
Isopiestic Determination of the Osmotic and Activity Coefficients of the {yNaH(2)PO(4)+(1-y)KH2PO4}(aq) System at T=298.15K
(Springer/Plenum Publishers, New York, 2019)
Isopiestic measurements have been made for aqueous mixtures of NaH2PO4 and KH2PO4 at T=(298.15 +/- 0.01) K, at NaH2PO4 ionic strength fractions y=(0, 0.19108, 0.38306, 0.58192, and 1), assuming that both electrolytes ...
Leaching of toxic elements from secondary alkaline lead slag and stabilized/solidified products
(Springer, New York, 2019)
Secondary alkaline lead slag (SALS), generated during lead-acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under ...
Improvement of the Textile Industry Wastewater Decolorization Process Using Capillary Microreactor Technology
(Springer International Publishing Ag, Cham, 2019)
Dyes are an important class of pollutants because large amounts are often found in the environment as a result of their extensive industrial use. Traditional wastewater treatment methods often lead to high energy costs, ...
Antibacterial activity of metal-containing clinoptilolite in natural seawater
(Desalination Publ, Hopkinton, 2019)
Antibacterial activity of a natural zeolite, clinoptilolite (Z), enriched with about 0.4-0.5 mmol of Ag (Ag-Z), Cu (Cu-Z) or Zn (Zn-Z) was tested toward two strains of Gram-negative bacteria - Escherichia coli and Acinetobacter ...
Adsorption performances of branched aminated waste polyacrylonitrile fibers: experimental versus modelling study
(Desalination Publ, Hopkinton, 2019)
Synthesis of branched aminated waste polyacrylonitrile (PAN) fibers, realized in a three addition/amidation successive steps, was performed in order to obtain AS3-PAN adsorbent. Influence of various operating parameters ...
CFD analysis of the influence of centrifugal separator geometry modification on the pulverized coal distribution at the burners
(Transactions of Famena, 2014)
This paper presents the results of 3D numerical flow simulation in the ventilation mill (VM) and air mixture channel (AMC) of Kostolac B power plant, where a centrifugal separator with adjustable blade angle is used. ...
Comparative Effects of Span 20 and Span 40 on Liposomes Release Properties
(Walter de Gruyter Gmbh, Berlin, 2017)
Liposomes are known as convenient carriers for a broad range of actives. The release rate of actives can be adjusted/controlled by the addition of different surfactants. The aim of this study was to compare the effects of ...
Origin of the Intrinsic Coercivity Field Variations and Magnetic Study of ε-Fe2O3
(Russian Journal of Physical Chemistry A, 2019)
Origin of the intrinsic coercivity field variations observed by hysteretic measurements established by Nikolic et al. was investigated in detail by ZFC/FC measurements. In this study, magnetic behavior of the samples is ...
Origin of the Intrinsic Coercivity Field Variations of ε-Fe2O3
(Russian Journal of Physical Chemistry A, 2019)
ε-Fe2O3 phase is recognized as an attractive material, in both technological and scientific point of view, since it can achieve very high room-temperature coercivity (10–20 kOe). In this paper, multi-phase samples Fe2O3/SiO2 ...
