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 ...
Mixed cobalt(III) complexes with aromatic amino acids and diamine. Part IV. Influence of noncovalent intraand interligand interactions on rotamer population of the S-phenylalaninato and S-tyrosinato side groups in (1,2-diaminoethane)bis(S-aminocarboxylato)cobalt(III) complexes
(Taylor & Francis, 2002)
Rotamer population of S -tyrosinato and S -phenylalaninato ligands side groups in diastereomers of (1,2-diaminoethane) bis ( S -aminocarboxylato)cobalt(III) complexes is calculated by vicinal and proton coupling constant ...
Intramolecular Barbier reaction in water: Cyclopentane and cyclohexane ring closure / Intramolekulska Barbier-ova reakcija u vodi - sinteza petočlanih i šestočlanih prstenova
(Serbian Chemical Society, 2002)
Zinc or indium promoted intramolecular Barbier reactions of aldehydes containing a suitably positioned allylic or propargylic halide unit afford unsaturated cyclic alcohols in moderate yields.
Electrochemical deposition and characterization of Zn /Co alloys and corrosion protection by electrodeposited epoxy coating on Zn /Co alloy
(Elsevier, 2002)
Zn-Co alloys electrochemically deposited on steel under various deposition conditions were investigated. The influence of deposition current density, temperature and composition of deposition solution on the phase structure ...
Regioselectivity of conjugate additions to monoalkyl-1,4-benzoquinones / Regioselektivnost konjugovane adicijena monoalkil-1,4-benzohinone
(Serbian Chemical Society, 2002)
The regioselectivity of the reaction of conjugate addition of thiols amines, methanol and hydrogen chloride with the monoalkyl-1,4-benzoquinones avarone and 2-tert-butyl- 1,4-benzoquinone was investigated. It was shown ...
Oxide electrocatalytic coatings obtained by the sol-gel procedure: Preparation and characterization / Oksidni elektrokatalizatori dobijeni sol-gel postupkom - dobijanje i karakterizacija
(Association of Chemical Engineers of Serbia, 2002)
The influence of different parameters (forced hydrolysis duration in the preparation of sols, alcohol addition in the sol mixture for application, as well as sol/alcohol mixture ageing time) on the morphology and electrochemical ...
Adsorption and corrosion inhibitive properties of some organic molecules on iron electrode in sulfuric acid
(Elsevier, 2002)
Adsorption and corrosion inhibitive properties of three different organic molecules: 2-naphthalenesulfonic acid, 2,7-naphthalenedisulfonic acid and 2-naphthol-3,6-disulfonic acid are investigated on Armco-iron electrode ...
Xanthones from Swertia punctata
(Oxford : Pergamon-Elsevier Science Ltd., 2002)
Isolation of 1-O-primeverosyl-3,8-dihydroxy-5-methoxyxanthone and 1-O-gentiobiosyl- 3,7-dimethoxy-8-hydroxyxanthone, along with five known xanthones, isobellidifolin, methylbellidifolin, isoswertianin, methylswertianin and ...
Polymorphic transformations of edible vegetable fats / Polimorfne transformacije jestivih biljnih masnoća
(Tehnološki fakultet, Naučni institut za ratarstvo i povrtarstvo i DOO "Industrijsko bilje", Novi Sad, 2002)
Triglycerides are characterized by complex melting behaviour, as reflected by multiple melting temperatures. They can solidify in different crystal structures and this polymorphism can be defined as the ability to reveal ...
Composition and antibacterial activity of Achillea asplenifolia essential oil
(Allured Publ Corp, Carol Stream, 2002)
The oil of a wild growing population of Achillea asplenifolia Vent. was studied for yield, composition and antibacterial activity. The major components in the oil were beta-caryophyllene (17.6%), germacrene D (15.6%) and ...
