The influence of mechanical activation on the morphological changes of Fe/BaTiO3 powder
(Elsevier, 2016)
Crystal structure and morphology of mechanically activated nanocrystalline Fe/BaTiO3 was investigated using a combination of spectroscopic and microscopic methods. These show that mechanical activation led to the creation ...
Influence of mechanical activation on functional properties of barium hexaferrite ceramics
(Elsevier, 2018)
Barium hexaferrite ceramics were prepared using mechanically activated mixtures of iron and barium titanate. The 60:40 mass% Fe:BaTiO3 powder mixtures were mechanically activated for different times (100–240 min) and ...
The LiFe(1-x)VxPO4/C Composite Synthesized by Gel-Combustion Method, with Improved Rate Capability and Cycle Life in Aerated Aqueous Solutions
(Elsevier, 2013)
The nitrate-(glycine + malonic acid)-assisted gel-combustion process, followed by a heat treatment at 750 °C under reductive atmosphere, was used as a fast and effective way to synthesize vanadium doped olivine incorporated ...
Stochastic time response of adsorption-based micro/nanobiosensors with a fluidic reaction chamber: The influence of mass transfer
(IEEE, 2017)
An approximate model for efficient analysis of stochastic time response of microfluidic biosensors is presented, that considers a random AD process coupled with mass transfer (convection and diffusion) of target substance ...
Adsorption-desorption noise in microfluidic biosensors operating in multianalyte environments
(Elsevier, 2015)
We present a theoretical model of adsorption-desorption (AD) noise in microfluidic biosensors operating in multianalyte environments. This noise is caused by the stochastic nature of the processes that generate the sensor ...
The influence of synthesis conditions on the redox behaviour of LiFePO4 in aqueous solution
(Elsevier, 2019)
To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in ...
Assessment of Spasticity by a Pendulum Test in SCI Patients Who Exercise FES Cycling or Receive only Conventional Therapy
(IEEE, 2018)
Increased muscle tone and exaggerated tendon reflexes characterize most of the individuals after a spinal cord injury (SCI). We estimated seven parameters from the pendulum test and used them to compare with the Ashworth ...
Structural investigation of mechanically activated ZnO powder
(Elsevier, 2015)
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 ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Elsevier, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
Fluctuations of the number of adsorbed molecules due to adsorption–desorption processes coupled with mass transfer and surface diffusion in bio/chemical MEMS sensors
(Elsevier, 2014)
In this study we have developed, for the first time, the comprehensive theoretical model of the fluctuations of the number of adsorbed molecules in MEMS chemical and biological sensors, taking into account the processes ...
