The diatomite: Type catalyst’s support / Nosač katalizatora tipa dijatomita
(Tehnološki fakultet, Naučni institut za ratarstvo i povrtarstvo i DOO "Industrijsko bilje", Novi Sad, 2002)
Hydrogenation of the animal fats and edible oils is a very important operation in the fats and oils industry. A catalyst usually used in industrial processes of the tallow and fat hydrogenation and in the vegetable oils ...
Photooxidation of n-heptanal in air: Norrish type I and II processes and quantum yield total pressure dependency
(Royal Society of Chemistry, 2002)
Dilute mixtures of n-heptanal in synthetic air (up to 100 ppm) were photolyzed with fluorescent UV lamps (275-380 nm) at 298 K. The main photooxidation products, identified and quantitatively analyzed by FTIR spectroscopy, ...
The application of modified macroporous poly(GMA-co-EGDMA) in the metal ions sorption from aqueous solutions / Primena modifikovanog makroporoznog poli(GMA-co-EGDMA) kopolimera u sorpciji jona metala iz vodenih rastvora
(Tehnika - Novi materijali, 2002)
Macro porous cross linked poly(GMA-co-EGDMA) copolymer synthesized by radical suspension copolywerization was modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine, EDA. Sorption capacities ...
The roughness analysis of metal coatings by STM technique: Part II: Analysis of zinc coatings / Analiza hrapavosti galvanskih prevlaka tehnikom skenirajuće tunelske mikroskopije - deo II - analiza prevlaka cinka
(Belgrade, Serbia : Engineering Society for Corrosion, 2002)
In this work is given the analysis of roughness of zinc coatings electrodeposited from a sulfate bath in the presence of dextrin and 2-hidroxi-benzaldehyde, by methodology which is described in part I of this work. It was ...
Polysulfone membranes for ultra and microfiltration / Polimerne membrane za ultra i mikrofiltraciju na bazi polisulfona
(Tehnika - Novi materijali, 2002)
The influence of the propionic acid as nonsolvent additive on the properties of the prepared polysulfone membranes was investigated. The obtained results show that the membranes prepared from the polymer solutions with ...
Ambient-temperature operation of nonequilibrium magnetoconcentration infrared detectors in InSb and HgCdTe
(IEEE Computer Society, 2002)
We present a theoretical and experimental consideration of magnetoconcentration-based long-wavelength infrared photodetectors with nonequilibrium Auger-process suppression, designed for room-temperature operation. Our ...
Mixed steroidal 1,2,4,5-tetraoxanes: Antimalarial and antimycobacterial activity
(American Chemical Society (ACS), 2002)
Mixed 1,2,4,5-tetraoxanes possessing simple spirocycloalkane and spirocholic acid-derived substituents were prepared and shown to have significantly higher in vitro antimalarial activity than bis-substituted tetraoxanes. ...
Phenanthrene and Methylphenanthrene Isomers in Maturity Assessment of Biodegraded Crude Oils (Sakhalin, Russia)
(Kazakhstan : al-Farabi Kazakh National University, 2002)
This paper is aimed at defining two new advantageous maturation parameters based on distribution and abundance of phenanthrene (P) and methylphenanthrene (MP) isomers in the tricyclic fraction of aromatic hydrocarbons: MPI ...
Comparative reflection and structural analyses of copper and zinc coatings electrodeposited from acid sulfate solutions without and with additives
(Elsevier, 2002)
Reflection and structural analyses of different copper and zinc coatings were performed. The coatings of copper obtained were from acid sulfate solutions in the absence and presence of thiourea. The coatings of zinc were ...
An estimation of the interfacial energy of the copper-copper sulphate solution interface and of the specific surface of copper powder / Procena međupovršinske energije bakar-rastvor bakar sulfata i specifične površine bakarnog praha
(Serbian Chemical Society, 2002)
Apossible way for the estimation of the interfacial energy of the copper – copper sulphate solution interface is proposed. The estimated value of (2.7±0.3) J cm-2 and the derived equations which relate the specific surface ...
