Luminescent carbon nanoparticles: effects of chemical functionalization, and evaluation of Ag+ sensing properties
(Royal Soc Chemistry, Cambridge, 2014)
Luminescent carbon-based nanoparticles, addressed as carbon dots (CDs), were synthesized at relatively low temperature from lactose following an easy and inexpensive procedure. Modification of their surface was done by ...
Fingerprint detection and using intercalated CdSe nanoparticles on non-porous surfaces
(Elsevier, Amsterdam, 2014)
A fluorescent nanocomposite based on the inclusion of CdSe quantum dots in porous phosphate heterostructures, functionalized with amino groups (PPH-NH2"CdSe), was synthesized, characterized and used for fingerprint detection. ...
Interdependence between structure and electrical characteristics in Sm-doped barium titanate
(Elsevier Science Sa, Lausanne, 2017)
Conventional solid-state method was used to prepare powders of pure and barium titanate (BT) doped with different concentration of samarium. Influence of samarium addition on the structure modification, grain growth ...
The effects of the pause to pulse ratio in the regime of pulsating overpotential on the formation of honeycomb-like structures
(Elsevier Science Inc, New York, 2009)
The formation of honeycomb-like structures in the pulsating overpotential (PO) regime was examined by scanning electron microscopy (SEM). The honeycomb-like structures obtained with a square-wave PO of different pause to ...
Microstructural characterization of mechanically activated ZnO-Cr2O3 system
(Elsevier Sci Ltd, Oxford, 2005)
An equimolar mixtures of starting ZnO and Cr2O3 powders were mechanically activated by grinding using a planetary ball mill for various periods of time (40-320min). Formation of nanocrystalline ZnCr2O4 as normal spine] ...
Biological activity of essential oils of Athamanta haynaldii and Myristica fragrans to gypsy moth larvae
(Industrial Crops and ProductsElsevierElsevier, 2013)
Ethanol solutions of essential oils obtained from Athmanta haynaldii and Myristica fragrans were tested for their toxicity and antifeedant activity against the second instar gypsy moth larvae in the laboratory bioassay. ...
The nature of structural changes in nanocrystalline ZnO powders under linear heating conditions
(Elsevier Sci Ltd, Oxford, 2004)
The nature of exothermal and irreversible structural changes observed during linear heating of nanocrystalline ZnO powders was investigated using differential scanning calorimetry, X ray, SEM and TEM analysis. Nanocrystalline ...
