Removal of organically bound sulfur from oil shale by iron(III)-ion generated-regenerated from pyrite by the action of Acidithiobacillus ferrooxidans - Research on a model system
(Elsevier, 2008)
Oil shale is one of the alternative sources of hydrocarbon fuels ("synthetic petroleum") but is characterized by increased sulfur and nitrogen contents, which represent even greater ecological problems in its use compared ...
Analysis and experimental demonstration of forced periodic operation of an adiabatic stirred tank reactor: Simultaneous modulation of inlet concentration and total flow-rate
(Elsevier, 2021)
It is well known, that forced periodic operation possesses the potential for process improvements. Nevertheless, only a small number of applications is reported, due to complex realization, limited predictability and high ...
The effects of repetitive alkaline/acid extractions of Saccharomyces cerevisiae cell wall on antioxidative and bifidogenic efficacy
(Wiley-Blackwell, Hoboken, 2012)
The aim of our study was to investigate the effects of consecutive alkaline/acid extraction of cell wall of bakers yeast (Saccharomyces cerevisiae) on products digestibility and antioxidative and bifidogenic activity. ...
Prediction of single particle settling velocities through liquid fluidized beds
(Powder Technology, 2009)
Single particle settling velocities through water fluidized beds of mono-sized glass spheres (dp = 0.645, 1.20, 1.94, 2.98 and 5 mm in diameter) were studied experimentally using a column, 40 mm in diameter. The settling ...
RuO2–TiO2 coated titanium anodes obtained by the sol–gel procedure and their electrochemical behaviour in the chlorine evolution reaction
(Elsevier, 1999)
TiO2 and RuO2 sols were obtained from RuCl3 and TiCl3 aqueous solutions by condensation and forced hydrolysis
at elevated temperature. The Ti supported coatings were obtained by the sol–gel method using a sol mixture in ...
Microbial bioremediation of the oil polluted environment and the sustainable development goals of pillar Planet of the Agenda 2030
(Srpinger Nature, 2024)
Sustainable development is a concept that is based on the development of the human society without compromising the natural resources, which should improve human lives and protect the environment for future generations. ...
Diagnostic of silicon piezoresistive pressure sensors by low frequency noise measurements
(Sensors and Actuators, A: Physical, 2008)
Low frequency noise measurements can be used as a tool in diagnostics of silicon diaphragm-based piezoresistive pressure sensors after the sensor encapsulation and oil filling process are finished. We measured noise in ...
Structural effects in electrocatalysis. Oxidation of D-glucose on single crystal platinum electrodes in alkaline solution
(Elsevier, 1991)
Electrochemical oxidation of D-glucose has been studied in 0.1 M NaOH on single crystal platinum electrodes with thirteen different orientations. The reaction rate depends strongly on the crystallographic orientation of ...
Electrochemical Oxidation of Methanol and Ethanol on Electrodeposited Pd and PdNi-Coated Electrodes
(Pleiades Publishing Inc, Moscow, 2017)
Electrodeposited PdNi and Pd samples were tested for methanol and ethanol oxidation reaction (MOR and EOR) in alkaline solution using cyclic voltammetry (CV) and chronoamperometric (CA) measurements. Among the CVs for the ...
Investigation of silicon anisotropic etching in alkaline solutions with propanol addition
(Institute of Electrical and Electronics Engineers Inc., 2008)
Different propanol isomers additives to 26 wt. % KOH water solution have been studied. It was stated that addition of both isomers result in changing etching anisotropy of (110) oriented corners on Si LT 100 >. For the ...
