Impact of the modification of carbon-supported, Pt-based catalysts by irreversibly adsorbed Sn, Ru and Rh on ethanol oxidation / Uticaj modifikacije platinskih nanokatalizatora ireverzibilnom adsorpcijom Sn, Ru i Rh na oksidaciju etanola
(Serbian Chemical Society, 2011)
The oxidation of ethanol was studied at Snad-, Ruad- and Rhad-modified and unmodified PtC, Pt3Sn/C and Pt3Ru2/C catalysts. Potentiodynamic, quasi-steady-state and chronoamperometric measurements were used to investtigate ...
Chemical composition of white currant seed extract / Hemijski sastav ekstrakta semenki bele ribizle
(Serbian Chemical Soc, Belgrade, 2011)
From the seeds of white currant (Ribes rubrum, cv. White Champagne), a new sesquiterpenoid glycoside 1 was isolated, along with two known compounds: dihydrophaseic acid 3'-O-b-D-glucopyranoside (2), and 3-carboxymethyl-i ...
Development directions of packaging made from polymer materials / Pravci razvoja ambalaže od polimernih materijala
(Association of Chemical Engineers of Serbia, 2011)
World packaging market achieves turnover of about $620 billion per year with one third of this amount being associated with packaging made from polymer materials. It is expected that this kind of packaging consumption will ...
Preliminary data on essential oil composition of the moss Rhodobryum ontariense (Kindb.) Kindb.
(Adac-Cryptogamie, Paris, 2011)
The essential oil composition of the moss Rhodobryum ontariense obtained by hydrodistillation was preliminary analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Thirteen compounds (86.41% ...
The effects of the cherry variety on the chemical and sensorial characteristics of cherry brandy / Uticaj varijeteta višnje na hemijske i senzorne karakteristike rakije višnjevače
(Serbian Chemical Soc, Belgrade, 2011)
The chemical and sensorial characteristics of cherry brandy produced from five cherry varieties (Oblacinska, Celery's 16, Rexle, Heiman's Ruby and Heiman's Conserve) grown in Serbia were studied. Gas chromatography and gas ...
A mathematical model of the current density distribution in electrochemical cells / Matematički model raspodele gustine struje u elektrohemijskim ćelijama
(Serbian Chemical Society, 2011)
An approach based on the equations of electrochemical kinetics for the estimation of the current density distribution in electrochemical cells is presented. This approach was employed for a theoretical explanation of the ...
Peroxisome Proliferator-Activated Receptors and Atherosclerosis
(Sage Publications Inc, Thousand Oaks, 2011)
The peroxisome proliferator-activated receptors (PPARs) represent the family of 3 nuclear receptor isoforms-PPAR alpha, -gamma, and -delta/beta, which are encoded by different genes. As lipid sensors, they are primarily ...
Synthesis and swelling behavior of polyurethane networks based on hyperbranched polymer / Sinteza i ispitivanje bubrenja umreženih poliuretana na bazi hiperrazgranatog polimera
(Association of Chemical Engineers of Serbia, 2011)
A series of six polyurethane (PU) networks was synthesized from Boltorn® hydroxy-functional hyperbranched polyester (HBP) of the second pseudo generation as a cross-linking agent, a,w-dihydroxy-(ethylene oxide-poly(dimet ...
Attachment of MEM piezoresistive silicon pressure sensor dies using different adhesives / Montaža čipova MEM silicijumskih piezorezistivnih senzora pritiska primenom različitih adheziva
(Association of Chemical Engineers of Serbia, 2011)
This paper gives comparison and discussion of adhesives used for attachment of silicon piezoresistive pressure sensor dies. Special attention is paid to low pressure sensor dies because of their extreme sensitivity on ...
