The thermal degradation of poly(di-n-propyl itaconate) and poly(di-iso-propyl itaconate)
(Elsevier Sci Ltd, Oxford, 2000)
The non-oxidative thermal degradation mechanism of poly(di-n-propyl-) (PDnPI) and poly(di-iso-propyl itaconate) (PDnPI) were investigated and compared to the structurally similar polymethacrylates. Analogous to the ...
Estimate of Si3N4 diffusion into Cu based filler metal
(Elsevier Science Ltd, 2000)
The diffusion phenomena occurring at the boundary between Si3N4 and active Cu based filler metal during Si3Nn/metal joining are discussed as a part of the general theory of reaction layer growth. The mechanism of reaction ...
The kinetics of the reaction of 6-substituted nicotinic acids and some p-substituted benzoic acids with diazodiphenylmethane in various alcohols / Kinetika reakcija 6-supstitutisanih nikotinskih kiselina i nekih p-supstituisanih benzoevih kiselina sa diazodifenilmetanom u različitim alkoholima
(Serbian Chemical Society, Belgrade, 2000)
Rate constants have been determined for the reactions of diazodiphenylmethane with a number of 6-substituted nicotinic acids and p-substituted benzoic acids in twelve alcohols. A comparative study was used to evaluate and ...
The significance of molecular weight for medical purpose application of PLLA / Značaj molske mase za primenu PLLA u medicini
(Association of Chemical Engineers of Serbia, 2000)
The influence of the molecular weight of poly (L-lactide) on the properties important for biomedical application are reviewed. The utilization of polylactides in sutures, drug release systems and bone reconstruction is ...
Immobilization/encapsulation of cells using electrostatic droplet generation - Experiments and theory
(Minerva Biotecnologica, 2000)
The mechanism of alginate droplet formation as well as experimental parameters for producing very small polymer microbeads (i,e, less then 100 microns diameter) using an electrostatic droplet generator were investigated, ...
The use of shade sorting method for the fabrics in garment manufacture / Primena metode sortiranja nijansi tkanine za izradu odevnih predmeta
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2000)
Shade sorting methods are designed with the aim to identify the pieces i.e. coloured materials from different dyelots, that could be used for the manufacture of a single garment in order to keep the colour difference between ...
The thermal degradation of poly(di-itaconates) / Termička degradacija poli(di-itakonata)
(Association of Chemical Engineers of Serbia, 2000)
The thermal degradation of poly(di-itaconates) is discussed with special emphasis on the Influence of the nature of the ester substituent. It was established that the following reactions occur during the thermal degradation ...
Have you ever thought about mole and its place in the international system of units? / Da li ste ikada razmišljali o molu i njegovom mestu u međunarodnom sistemu jedinica?
(Srpsko hemijsko društvo, Beograd, 2000)
A short historical review of measuring and units has been given in the first part of this paper. The most attention has been paid to the decimal metric system and to the development of International system of units (SI). ...
