Immobilization of Cell Wall Invertase Modified with Glutaraldehyde for Continuous Production of Invert Sugar
(American Chemical Society (ACS), 2010)
Yeast cell wall invertase (CWI) was modified with dimethyl suberimidate, glutaraldehyde, formaldehyde, and sodium periodate. Retained activity after modification was 45% for CWI modified with formaldehyde, 77% for CWI ...
Field effect transistor based on protons as charge carriers
(Elsevier, 2010)
We demonstrated a field effect transistor based on the modulation of the proton flow in confined water-containing nanochannels. The device resembles an MOSFET transistor with the difference that the charge carriers here ...
Modelling of thermopile-based MEMS sensors using analytical and numerical techniques
(27th International Conference on Microelectronics, MIEL 2010 - Proceedings, 2010)
In this paper the thermoelectrical behavior of thermopile-based MEMS sensors is reported using analytical and numerical techniques. It is also shown that experimental results for specific sensors are in excellent agreement ...
Reduction of Oxygen at a NaX-Ag Composite Electrode and Its Application to the Determination of Oxygen in Aqueous Media
(Maik Nauka/Interperiodica/Springer, New York, 2010)
A composite mixture Ag-NaX zeolite (silver concentration 16.7% w/w) is synthesized usingimpregnation and thermal decomposition. For silver impregnation, a solution of an Ag acetylacetonate complex in acetone was used. ...
Mixed pillared bentonite for electrooxidation of phenol
(Elsevier, 2010)
Bentonite was pillared with Al, Al-Cu, Al-Fe or Al-Co poly(hydroxo metal) cations for electrochemical oxidation of phenol in acidic solution. Multisweep cyclic voltammetry was applied to analyze the behavior of the bentonite ...
Synthesis and Structure of New 5-(Arylidene)-3-(4-methylbenzoyl)thiazolidine-2,4-diones
(Wiley-Blackwell Publishing, Inc, Malden, 2010)
The derivatives of 5-substituted-2,4-thiazolidinedione have a broad spectrum of biological activities. In this article, new 5-(arylidene)-3-(4-methylbenzoyl)thiayolidine-2,4-diones 3a-k, with arylidene groups such as ...
The impact of Schiff bases on antibiotic production by Streptomyces hygroscopicus
(Medicinal Chemistry Research, 2010)
A media consisting of isatin-Schiff bases (isatin-3-thiosemicarbazone, isatin-3-semicarbazone, and isatin-3-phenylhydrazone) was developed to maximize the production of antibiotics Hexaene H-85 and Azalomycine B by ...
Purification and characterisation of Saccharomyces cerevisiae external invertase isoforms
(Elsevier Sci Ltd, Oxford, 2010)
Four external invertase isoforms (EINV1, EINV2, EINV3 and EINV4) from Saccharomyces cerevisiae were highly purified by isoelectric precipitation, ethanol precipitation, ion-exchange on QAE-Sephadex and gel filtration using ...
Protein subunit interfaces: a statistical analysis of hot spots in Sm proteins
(Springer, New York, 2010)
The distinguishing property of Sm protein associations is very high stability. In order to understand this property, we analyzed the interfaces and compared the properties of Sm protein interfaces with those of a test set, ...
The influence of pH on removal of H2S and natural organic matter by anion resin
(Desalination Publ, Hopkinton, 2010)
A number of experiments with "specific"ground water from the Pannonian Plains (the Republic of Serbia) were conducted in order to define a technological process for drinking water treatment. The "specificity"of this raw ...
