Morphological, structural, and functional properties of vertically aligned carbon nanotubes deposited on porous silicon layers by ultrasonic spray pyrolysis
(Elsevier, 2020)
In this work, we reported the fabrication of hybrid structures by growing the multi-walled carbon nanotubes (MWCNT) on porous silicon (PS) as a template. Aligned multi-walled carbon nanotubes have been successfully synthesized ...
Electronic ceramics fractal microstructure analysis - Minkowski Hull and grain boundaries
(Taylor & Francis, 2019)
Consolidation parameters have influence and can be used to control structure of BaTiO3 based materials. Microstructure and dielectric properties of Yb2O3 doped BaTiO3-ceramics, sintered from 1320 °C to 1380 °C have been ...
Rare-earth (Gd 3+ ,Yb 3+ /Tm 3+ , Eu 3+ ) co-doped hydroxyapatite as magnetic, up-conversion and down-conversion materials for multimodal imaging
(Springer Nature, 2019)
Taking advantage of the flexibility of the apatite structure, nano- and micro-particles of hydroxyapatite (HAp) were doped with different combinations of rare earth ions (RE3+ = Gd, Eu, Yb, Tm) to achieve a synergy among ...
Electronic structure and X-ray spectroscopic properties of the HfFe2Si2 compound
(West Ukrainian Physical Society, 2019)
The valence band electronic structure of HfFe2Si2 has been established for the first time based on X-ray emission spectroscopy measurements. The band structure and X-ray emission spectra have been also obtained theoretically ...
Self-limiting interactions in 2D–0D system: A case study of graphene oxide and 12-tungstophosphoric acid nanocomposite
(Carbon, 2020)
In the present study we investigated the interaction between 12-tungstophosphoric acid (WPA) and graphene oxide (GO) in their nanocomposite by utilizing the loading of WPA as an intrinsic parameter for interaction tuning. ...
Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Lausanne : Elsevier Science, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
Identification of intermetallic compounds in thin layers of electrodeposited Cu–Cd alloys using electrochemical techniques
(Taylor & Francis INC, 1991)
An attempt was made to analyse the phase structure of thin layers of electrodeposited Cu–Cd alloys using anodic linear sweep voltammetry combined with a potentiostatic pulse technique (ALSV–PPT). The results were compared ...
Composite poly(DL-lactide-co-glycolide)/poly(acrylic acid) hydrogels synthesized using UV and gamma irradiation: comparison of material properties
(Elsevier, 2020)
Composite hydrogels capable of controlled drug delivery via ion exchange are an interesting group of materials for the construction of implantable drug reservoirs for electrically charged drugs. In this study, we synthesized ...
Evaluation of nano grain growth of TiO2 fibers fabricated via centrifugal jet spinning
(Elsevier, 2020)
Nanomaterials form the main thrust for modern day technological and industrial applications, including but not limited to, super-capacitors, membranes, batteries, filters, sensors, tissue engineering, wound dressing, ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
