Asymmetric hydrogel membranes for heavy metal adsorption
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Hydrogels containing strong acid groups have been used in the past for the removal of heavy metals. Unfortunately such hydrogels exhibit poor mechanical properties and are generally difficult to handle. In this work we ...
Sol-gel synthesis of Li2FeSiO4/C
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Lithium transition-metal orthosilicates with general formula Li2MSiO4 (M = Fe, Mn, Co, etc.) have attracted a lot of interest due to their potentially high theoretical capacities arising from the possibility of the extraction ...
Freeze-drying method for LiFePO4/C composite processing
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Based on its high capacity, stability, low toxicity and low cost of raw materials, phosphoolivine LiFePO4 became a material of great interest for Li-ion battery application. Synthesis of LiFePO4/C cathode material was ...
Biomaterials and their application in preprosthetic surgical procedure
(Belgrade : Institute of Technical Sciences of SASA, 2013)
The loss of teeth and damage to the jaw bone occur under different circumstances. The deficit may be the result of wearing inadequate dentures, residual ridge resorption, osteoporosis, periodontal disease, trauma, tumors, ...
The influence of mechanical activation on the structure of ZnO
(Belgrade : Institute of Technical Sciences of SASA, 2013)
In this paper, the authors investigated the influence of mechanicall activation of ZnO powder on crystal and micro structure. Because of its structure, ZnO could be used like filler in polymer ceramics nanocompozites. ...
