Phytochemical study of the genus amphoricarpos / Фитохемијско истраживање биљног рода Amphoricarpos
(Serbian Chemical Society, 2021)
Phytochemistry deals with the study of secondary metabolites produced by plants that synthesize these compounds for many reasons, including their own protection against attack of herbivores and plant diseases. Secondary ...
Synthesis and pharmacological evaluation of several N-(2-nitrophenyl) piperazine derivatives / Sinteza i farmakološko ispitivanje novih derivata N-(2-nitrofenil) piperazina
(Serbian Chemical Society, 2007)
Six newly synthesized heterocyclic (2-nitrophenyl)piperazines, with a specific structure of the heteroaryl group, whichmimics the catechol moiety of dopamine (benzimidazoles and substituted benzimidazoles), were evaluated ...
Polyphenolic compounds in seeds from some grape cultivars grown in Serbia / Polifenolna jedinjenja iz semenki osam sorti grožđa gajenih u Srbiji
(Serbian Chemical Soc, Belgrade, 2010)
Seed extracts from eight grape cultivars (Vitis vinifera) growing in Serbia were screened for their polyphenolic composition by means of HPLC/ /PDA/ESI/MS analysis. The study revealed 34 phenolic compounds belonging to the ...
Does cholesterol bound to haemoglobin affect the anti-oxidant enzyme defence system in human erythrocytes? / Da li holesterol vezan za hemoglobin utiče na anti-oksidativni enzimski sistem u humanim eritrocitima
(Belgrade : Serbian Chemical Society, 2007)
U prethodnom radu pokazano je da lipidna frakcija koja se javlja u hemolizatu
zdravih ljudi predstavlja holesterol (asosovan sa fosfolipidima) čvrsto vezan za hemoglobin
(Hb-Ch). U ovom radu ispitivan je uticaj Hb-Ch na ...
The Determination of the Optimum Current Wave in Reversing Current Metal Electrodeposition / Određivanje optimalnog odnosa talasa reversne struje pri elektrohemijskom taloženju metala
(Belgrade : Serbian Chemical Society, 1998)
The experimental procedure for the determination of the optimum reversing current wave, producing uniformlly distributed polycrystalline deposits, is given. First, deposition at the maximum current density for different ...
Fabrication of Sio2-based microcantilevers by anisotropic chemical etching of (100) single crystal Si / Izrada mikrogredica od SiO2 anizotropnim hemijskim nagrizanjem na monokristalnom silicijumu (100) orijentacije
(Serbian Chemical Society, 2007)
The undercutting process of thermal SiO2 microcantilevers with different orientations on (100) Si wafer was studied. The silicon substrate was removed by anisotropic chemical etching with a 25 wt. % aqueous solution of ...
Preparation and modification of itaconic anhydride-methyl methacrylate copolymers / Синтеза и модификација кополимера анхидрида итаконске киселине и метил-метакрилата
(Belgrade : Serbian Chemical Society, 2007)
The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60°C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios ...
The effects of a magnetic field on the morphologies of nickel and copper deposits: The concept of 'effective overpotential' / Uticaj primenjenih magnetnih polja na morfologije taloga nikla i bakra - koncept 'efektivne prenapetosti'
(Serbian Chemical Society, 2007)
The morphologies of nickel and copper deposits obtained without applied magnetic fields, and with both parallel and perpendicular applied magnetic fields were examined by the scanning electron microscopy (SEM) technique. ...
Phytochemicals from bryophytes: Structures and biological activity / Фитохемикалије из бриофита: структура и биолошке активности
(Serbian Chemical Society, 2021)
Little attention has been paid to the bryophytes as sources for human diet despite the presence of 23,000 species in the world. Some mosses contain Vitamin B1, tocopherols, prostaglandin-like highly unsaturated fatty acids ...
Prediction of the particle circulation rate in a draft tube spouted bed suspension dryer / Predviđanje cirkulacije čestica u sušioniku za suspenzije sa modifikovanim fontanskim slojem
(Serbian Chemical Society, 2006)
A model for predicting the particle circulation rate in a draft tube spouted bed dryer with inert particles is proposed and verified. The calculation algorithm requires three input values: the gas velocity in the draft ...
