The effects of cytokinin types and their concentration on in vitro multiplication of sweet cherry rootstock Gisela 5 / Uticaj vrste i koncentracije citokinina na in vitro multiplikaciju podloge za trešnju Gisela 5
(Naučno voćarsko društvo Srbije, Čačak, 2014)
The most important aspect of successful micropropagation. Among other in vitro factors, is to use the optimal types and concentrations of plant growth regulators. With the aim of optimization of in vitro multiplication of ...
Modification of natural clinoptilolite for nitrate removal from aqueous media
(Srpsko hemijsko društvo, Beograd, 2014)
Natural zeolitic tuff from the Zlatokop mine (Vranjska Banja deposit, Serbia) was investigated as the starting material to obtain a low cost adsorbent for the removal of nitrate from aqueous media. The tuff rich in zeolite, ...
Ballistic Properties of Hybrid Thermoplastic Composites with Silica Nanoparticles
(Inda, Cary, 2014)
Multi-axial aramid fabrics have a wide range of applications in the construction of composite structures for body armor. Nanoparticles, which include nanosilica, are one of the most common nanofillers for these structures. ...
Thermal, morphological, and mechanical properties of ethyl vanillin immobilized in polyvinyl alcohol by electrospinning process
