Viability of newly developed process for catalytic conversion of bio-glicerin into various 'green chemical' and development opportunities for Serbia
(Institut za istraživanja i projektovanja u privredi, Beograd, 2016)
Crude bio-glycerin is a by-product in the production of biodiesel. An economically efficient valorization of crude bio-glycerin usually significantly defines the profitability of the biodiesel plant. A strong technological ...
Properties of adsorbent obtained by conventional and under microwave irradiation / Svojstva adsorbensa dobijenog aktivacijom bentonita na konvencionalan način i u mikrotalasnom polju
(Savez inženjera i tehničara Srbije, 2012)
In this paper the effect of acid activation by conventional and under microwave irradiation on the textural and structural properties of bentonite was studied. The adsorbents were characterized by powder X-ray diffraction ...
Micromechanical properties of composite systems consisting of electrodeposited nickel coatings on different substrates / Mikromehanička svojstva kompozitnih sistema formiranih elektrohemijskim taloženjem filmova nikla i bakra na različitim podlogama
(Savez inženjera i tehničara Srbije, 2012)
Fine-grained nickel and copper thin films were electrodeposited (ED) from self-made sulphamate and sulphate electrolytes, respectively, on different substrates. The substrates were single crystal silicon with two different ...
