An analytical 3-D model for small dimensions MOSFETs' threshold voltage
(2000 22nd International Conference on Microelectronics, MIEL 2000, 2000)
This paper has presented an analytical three-dimensional (3D) model for threshold voltage of small dimensions MOSFETs with an experimental dependence of acceptor concentration in the channel. The corresponding algorithms ...
Corrosion behaviour of epoxy coatings electrodeposited on galvanized steel and steel modified by Zn-Ni alloys
(Elsevier Science Sa, Lausanne, 2000)
The electrochemical and transport properties and thermal stability of epoxy coatings electrodeposited on hot-dip galvanized steel and steel modified by Zn-Ni alloys were investigated during exposure to 3% NaCl solution. ...
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). ...
