New Hybrid Properties of TiO2 Nanoparticles Surface Modified With Catecholate Type Ligands
(Springer, New York, 2010)
Surface modification of nanocrystalline TiO2 particles (45 ) with bidentate benzene derivatives (catechol, pyrogallol, and gallic acid) was found to alter optical properties of nanoparticles. The formation of the inner-sphere ...
Microhardness analysis of thin metallic multilayer composite films on copper substrates
(University of Belgrade, Technical Faculty, Bor, 2011)
Composite systems of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength ...
Effect of the Degree of Conversion on Mechanical Properties and Monomer Elution from Self-, Dual- and Light-Cured Core Composites
(Materials, 2021)
The objective of this work was to measure and correlate the degree of conversion (DC), mechanical properties and monomer elution from self-, dual- and light-cured core composites. Five samples of each of the following ...
Semi-Crystalline Copolymer Hydrogels as Smart Drug Carriers: In Vitro Thermo-Responsive Naproxen Release Study
(Pharmaceutics, 2021)
In this study, poly(N-isopropylacrylamide-co-2-hydroxypropyl methacrylate) hydrogels were synthesized using free radical initiated copolymerization method. Four hydrogels with different cross-linker concentrations were ...
NIR photo-driven upconversion in NaYF4:Yb,Er/PLGA particles for in vitro bioimaging of cancer cells
(Elsevier Science Bv, Amsterdam, 2018)
Lanthanide-doped fluoride up-converting nanoparticles (UCNPs) represent the new class of imaging contrast agents which hold great potential for overcoming existing problems associated with traditionally used dyes, proteins ...
Glass transition and polymer dynamics in silver/poly(methyl methacrylate) nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Dynamic mechanical-thermal analysis (DMTA), differential scanning calorimetry (DSC), thermally stimulated depolarization currents (TSDC) and, mainly, broadband dielectric relaxation spectroscopy (DRS) were employed to ...
Technologically Sustainable Route for Metals Valorization from Jarosite-PbAg Sludge
(Minerals, 2021)
By-products from zinc hydrometallurgy are classified as hazardous waste with strong leaching toxicities. Even though numerous research papers are dedicated to valorizing valuable metals in it, the primary management route ...
Cardiac tissue engineering: effects of bioreactor flow environment on tissue constructs
(Wiley, Hoboken, 2006)
The limited ability of cardiac muscle to regenerate after injury and the small number of organs available for transplantation motivate studies aimed at curative treatment options. Tissue engineering based on the integrated ...
Influence of microenvironment on cell adhesion, polarization, and migration
(Dove Medical Press Ltd, Albany, 2012)
Preparation, characterization and mechanical properties of rare-earth-based nanocomposites
(University of Belgrade, Technical Faculty, Bor, 2012)
This study reports research related to different preparation methods and characterization of polymer nanocomposites for optical applications. The Eu-ion doped Gd2O3 nanophosphor powder with different nanoparticle content ...
