Bonding ability of magnesium doped hydroxyapatite based insert with Clearfil dental adhesive
(Belgrade : Institut za istraživanja i projektovanja u privredi, 2020)
Decayed or damaged tooth structure is widely being repaired with the resin
based dental composites (RBCs) in the clinical practice. However, relatively high failure rate
and short lifespan are common in the case of the ...
Analysis of floating-head heat exchanger bolts failure
(Timisoara, Romania, 2011)
As-received floating-head heat exchanger bolts were broken (BB) and deposite-coated. The aim was to estimate
a cause of their failure. The new bolts of the same material were used as a reference material (reference bolt ...

The effect of sulfuric acid treatment on physicochemical properties of g-C3N4 and its efficiency for photocatalytic reduction of Cr(VI)
(Savez hemijskih inženjera Srbije, 2024)
A great deal of interest is directed towards g-C3N4 (CN) for the photocatalytic reduction of Cr(VI), due to its high stability in acidic conditions and medium band gap (~2,7 eV), but its practical application is limited ...
Heterojunctions based on g-C3N4 for the photocatalytic reduction of Cr(VI)
(Belgrade : Institute of Technical Sciences of SASA, 2022)
A potential visible light photocatalyst, metal-free graphitic carbon nitride (g-C3N4) has
attracted great attention as a green photocatalyst due to its simple preparation, high stability,
low cost and medium band gap of ...
Biodegradable coatings improved mechanical properties and bioactivity of sintered calcium phosphate scaffolds
(Belgrade : Materials Research Society of Serbia, 2022)
CRYSTAL STRUCTURE OF (2,2’-DIPYRIDYLAMINE)-μ3-(1,3-BENZENEDICARBOXYLATO)ZINC(II) / KRISTALNA STRUKTURA (2,2’-DIPIRIDILAMIN)-μ3-(1,3-BENZENDIKARBOKSILATO)CINKA(II)
(Beograd : Srpsko kristalografsko društvo, 2013)
Designing of mixed Zn(II) complexes with benzenedicarboxylato and amine ligands attracts much attention because of the amazing chain, layer or 3D framework structures that arise [1]. Besides the variety of topologies, these ...
