Phoenix spectra for determination of the fundamental stellar parameters
(Institute of Physics, Belgrade, SerbiaAstronomical Observatory Belgrade, Serbia, 2021)
We present a set of calculated spectra for stellar atmospheres. Temperature is
varied from 2500-10000K, log g from 0.5 to 5.5, z from 0.5 to 2.5 and alpha
enhancement -0.2 to +0.8. Our aim is to use these spectra as ...
The effect of natural modifiers for starch hydrophobization on performance of composite based on ethylene acrylic acid copolymer
(Wiley, Hoboken, 2021)
As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based ...
