Removal of ethylene oxide from waste gases by absorption / Uklanjanje etilen-oksida iz otpadnih gasova postupkom apsorpcije
(Association of Chemical Engineers of Serbia, 2011)
Ethylene oxide (EtO) is an organic compound, which is used as a starting material in the production of polymers and as sterilizing agent for thermolabile materials. Although ethylene oxide is not common as an organic ...
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 ...
The qualitative determination of oseltamivir phosphate in Tamiflu® capsule by cyclic voltammetry / Kvalitativno određivanje oseltamivir-fosfata u Tamiflu® kapsulama pomoću ciklične voltametrije
(Association of Chemical Engineers of Serbia, 2011)
A gold electrode was used in the voltammetric determination of oseltamivir phosphate standard in 0.05 M NaHCO3. Oseltamivir phosphate as a standard and as a component of Tamiflu® capsule exhibited the identical cyclic ...
Response surface optimisation for activation of bentonite with microwave irradiation / Optimalno faktorno planiranje procesa kiselinske aktivacije bentonita u mikrotalasnom polju
(Association of Chemical Engineers of Serbia, 2011)
In this study, the statistical design of the experimental method was applied on the process of acid activation of bentonite with microwave irradiation. The influence of activation parameters (time, acid normality and ...
The peculiarities of electrochemical deposition and morphology of Zn-Mn alloy coatings obtained from pyrophosphate electrolyte / Specifičnosti elektrohemijskog taloženja i morfologija Zn-Mn prevlaka dobijenih iz pirofosfatnog elektrolita
(Association of Chemical Engineers of Serbia, 2011)
The first successful attempt to electrodeposit Zn-Mn alloy coatings from alkaline bath was made only a few years ago. In this kind of solution, potassium pyrophosphate (K4P2O7) serves both as a complexing agent and as the ...
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 ...
