Decomposition of methomyl over supported iron catalysts
(Springer, Dordrecht, 2007)
Catalytic wet peroxide oxidation of methomyl over Fe-ZSM-5 and AlFe-pillared montmorillonite was carried out at room temperature, in a glass batch reactor, under constant airflow and halogen lamp light. Both catalysts have ...
Influence of the mobile-phase modifier on the retention of some para-substituted amides; Correlation with compound lipophilicity
(Springer Heidelberg, Heidelberg, 2003)
The chromatographic behavior of Para-substituted amides of alpha-phenylacetic, benzoic, propanoic, and 2,2-dimethylpropanoic acid has been studied in reversed-phase thin-layer chromatography on silica gel impregnated with ...
Surface carriers' concentration dynamics caused by a small alternating applied voltage
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
One of our previous papers was devoted to threshold voltage in MOSFETs and MODFETs viewed as a problem of nonlinear dynamics. The behavior of surface carriers' concentration under D.C. (direct current) applied voltage has ...
TIMS and MALDI TOF of endohedral Li-n"C-70 (n=1-3) metallofullerenes
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
Using the ion implantation technique (introducing negatively charged fullerene into a low temperature lithium plasma column by a strong axial magnetic field) endohedral fullerenes Li"C-70, Li-2"C-70 and Li-3"C-70 were ...
Reversal of substituent effect on electronic absorption spectra of N-(4-substituted phenyl)-benzamides in different solvents
(Natl Inst Science Communication, New Delhi, 2002)
Absorption spectra of eleven N-(4-substituted phenyl)-benzamides have been recorded in ten solvents in the range 200400 nm. The substituents at the phenyl nucleus are as follows: N (CH3)(2), OCH3, CH3, H, Cl, Br, F, CN, ...
Influence of increased temperature on clay fast drying process
(Revista Romana de Materiale/ Romanian Journal of Materials, 2009)
In this paper are presented testing results during process of fast drying at conditions of increased temperature. Three different masonry raw materials were examined using recircular laboratory dryer with air recirculation. ...
Rheological quantification of liposomes aggregation
(Minerva Biotecnologica, 2005)
Aim. The aggregation of phospholipid vesicles (liposomes) in water is analyzed experimentally and theoretically and compared with the well-examined alumina dispersions. The steady-state aggregation followed rheologically ...
HEMT carrier mobility analytical model
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
In this paper a new analytical carrier mobility model of a heterostructure unipolar transistor, High Electron Mobility Transistor (HEMT), is presented. The influence of the two dimensional electron gas confined in a HEMT ...
The influence of surface modification on related functional properties of wool and hemp
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The new concept of the combined treatment consisting of specific fibre surface tailoring and activation prior to biopolymer or enzyme post-application is introduced. Low-temperature plasma treatment is considered as very ...
The influence of bonding agents in improving interactionsin composite propellants determined using image analysis
(Wiley, Hoboken, 2008)
Binder-oxidizer interactions in rocket composite propellants can be improved using adequate bonding agents. In the present work, the effectiveness of different 1,3,5-trisubstituted isocyanurates was determined by stereo ...
