Structural investigation of mechanically activated ZnO powder
Abstract Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ...
45S5Bioglass®-based scaffolds coated with selenium nanoparticles or with poly(lactide-co-glycolide)/selenium particles: Processing, evaluation and antibacterial activity
(Colloids and Surfaces B: Biointerfaces, 2015)
n the bone tissue engineering field, there is a growing interest in the application of bioactive glass scaffolds (45S5Bioglass®) due to their bone bonding ability, osteoconductivity and osteoinductivity. However, such ...
Dewatering of sludge obtained by neutralisation from sulfuric-acid waste solutions / Odvodnjavanje mulja dobijenog neutralizacijom sumporno-kiselih otpadnih rastvora
(Bor: Mining and Metallurgy Institute, 2014)
The aim of this paper was to investigate the possibility of removing the liquid phase from the sludge using the mechanical dewatering methods. The sludge was obtained by neutralization of sulfuric acid waste solution from ...
Electrochemically deposited nano fibrous polyanilne for amperometric determination of glucose
(Bucharest : National Institute of Materials Physics, 2012)
Electrochemical deposition of polyaniline (PANI) on graphite electrode was performed galvanostaticaly at constant current density in the range of 1.0 – 5.0 mA cm-2 from aqueous acidic electrolyte containing aniline monomer. ...
Optical far infrared properties of FeS2
(Bucharest: Integra Natura Omnia et Aeterna, 2010)
In this paper are presented the far-infrared reflectivity spectra for a cleaved FeS 2 sample measured at roam temperature and at 77 K.
Determination of Particle Size Distributions by Laser Diffraction
(Beograd : Savez inženjera i tehničara Srbije, 2012)
The paper deals with the main principles of determination of particle size distribution using Mastersizer 2000, Malvern Instruments Ltd., UK. On the example of several problems we have demonstrated that the method is not ...
The influence of fluorine doping on the structural and electrical properties of the LiFePO4 powder
Low intrinsic electronic conductivity is the main disadvantage of LiFePO4 when used as a cathode material in lithium ion batteries. The paper offers experimental proofs of the theoretical prediction that fluorine doping ...
Sintering of fly ash based composites with zeolite and bentonite addition for application in construction materials
(International Institute for the Science of Sintering, 2017)
Due to pozzolanic characteristics, fly ash is commonly used as a cement replacement in construction composites. Addition of natural clays with sorption ability (i.e. zeolite and bentonite) in to the fly ash based construction ...
Towards implementation of far background tracker for vision-based robot navigation
Visual tracking of stationary points positioned at a large distance from moving robot provides a good basis for determining robot orientation and it may speed-up operation of structure from motion and navigation algorithms. ...
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
