An adsorption-based mercury sensor with continuous readout
(Springer-Verlag, 2013)
A novel readout procedure for a mercury sensor has been proposed. The sensor is based on the surface adsorption. Mercury vapor is adsorbed at the surface of a thin gold layer patterned into four meanders which are connected ...
Detection Limit for an Adsorption-Based Mercury Sensor
(Elsevier, 2013)
A novel readout procedure for the determination of detection limit at an adsorption-based mercury sensor is described. The procedure is based on the evaluation of the initial voltage slope in time evolution of adsorbed ...
Sintering of the mechanically activated MgO-TiO2 system
(Hanyang University Press, 2013)
Mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for a time interval from 0 to 120 minutes. The influence of the mechanical activation on the phase composition and crystal structure have ...
Influence of MoO3 on sintering temperature of mechanically activated MgO-Al2O3-SiO2 system
(Belgrade : Serbian Ceramic Society, 2013)
Cordierite, 2MgO⋅2Al2O3⋅5SiO2, is a very attractive high-temperature ceramic material, due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good ...
Density and electrical properties of cordierite based ceramics as function of compaction pressure
(Belgrade : Serbian Ceramic Society, 2013)
Mechanical activation is widely used and relatively inexpensive procedure for sintering process sample preparation. However, the influence of pressure, which is used for compaction, has not been completely investigated. ...
Influence of one activated component on the sintering process of three phase system
(Belgrade : Materials Research Society of Serbia, 2013)
According to its low temperature thermal expansion coefficient, low dielectric constant, also good mechanical properties, cordierite, 2MgO×2Al2O3×5SiO2, represents a very attractive hightemperature ceramic material. In ...
Influence of MoO3 on cordierite ceramics sintering and crystallization
(Belgrade : Materials Research Society of Serbia, 2013)
The influence of MoO3 on the process of cordierite ceramics preparation, 2MgO-2Al2O3-5SiO2 (MAS) was researched by sintering followed binary systems: MgO/MoO3 (sintered at 850 ºC and 1000 ºC), Al2O3/Bi2O3 and SiO2/Bi2O3 ...
Nanoparticles of cobalt-substituted hydroxyapatite in regeneration of mandibular osteoporotic bones
(Springer, 2013)
Indications exist that paramagnetic calcium phosphates may be able to promote regeneration of bone faster than their regular, diamagnetic counterparts. In this study, analyzed was the influence of paramagnetic cobalt-substituted ...
Multifunctional hydroxyapatite and poly(D,L-lactide-co-glycolide) nanoparticles for the local delivery of cholecalciferol
(Elsevier, 2013)
Cholecalciferol, vitamin D3, plays an important role in bone metabolism by regulating extracellular levels of calcium. Presented here is a study on the effects of the local delivery of cholecalciferol (D3) using nanoparticulate ...
Ultrasonic spray pyrolysis of surface modified TiO2 nanoparticles with dopamine
(Materials Chemistry and Physics, 2013)
Spherical, submicronic TiO2 powder particles were prepared in the low temperature process of ultrasonic spray pyrolysis (150 °C) by using as a precursor aqueous colloidal solutions consisting of surface modified 45 Å TiO2 ...
