Surface Analyses of PVDF/NMP/[EMIM][TFSI] Solid Polymer Electrolyte
(MDPI, 2021-08-11)
Thermal treatment conditions of solid polymer polymer electrolyte (SPE) were studied with respect to their impact on the surface morphology, phase composition and chemical composition of an imidazolium ionic-liquid-based ...
Electrical and optical characterization of Os-substituted rare-earth orthoferrite YbFeO3-gamma powders
(Springer Nature, 2021-01-02)
The electrical properties of Os-doped YbFeO3 (YbFO) powders prepared by solid-state reaction have been studied by Impedance Spectrometer/Impedance Spectrometer. SEM, XPS and Raman spectroscopy were utilized for understanding ...
Low-energy electron microscopy of graphene outside UHV: electron-induced removal of PMMA residues used for graphene transfer
(Elsevier, 2020-05-01)
Two-dimensional materials, such as graphene, are usually prepared by chemical vapor deposition (CVD) on selected substrates, and their transfer is completed with a supporting layer, mostly polymethyl methacrylate (PMMA). ...
Characterization of Polyvinylidene Fluoride (PVDF) Electrospun Fibers Doped by Carbon Flakes
(MDPI, 2020-11-24)
Polyvinylidene fluoride (PVDF) is a modern polymer material used in a wide variety of ways. Thanks to its excellent resistance to chemical or thermal degradation and low reactivity, it finds use in biology, chemistry, and ...
Characterization of GaAs Solar Cells under Supercontinuum Long-Time Illumination
(MDPI, 2021-01-19)
This work is dedicated to the description of the degradation of GaAs solar cells under continuous laser irradiation. Constant and strong exposure of the solar cell was performed over two months. Time-dependent electrical ...
PVDF Fibers Modification by Nitrate Salts Doping
(MDPI, 2021-07-24)
The method of inclusion of various additives into a polymer depends highly on the material in question and the desired effect. In the case of this paper, nitride salts were introduced into polyvinylidene fluoride fibers ...
Characterization of the native oxide on CdTe surfaces
(Sciendo, 2019-05-29)
This study focuses on the description of oxidation of CdTe monocrystal surfaces after selective chemical etching. Measurements of surface morphology of the oxides occurring in short time are valuable for deeper understanding ...
Algal Biomass Analysis by Laser-Based Analytical Techniques - A Review

Algal biomass that is represented mainly by commercially grown algal strains has recently found many potential applications in various fields of interest. Its utilization has been found advantageous in the fields of ...
Comprehensive characterization of PVDF nanofibers at macro- and nanolevel
(MDPI, 2022-02-01)
This study is focused on the characterization and investigation of polyvinylidene fluoride (PVDF) nanofibers from the point of view of macro- and nanometer level. The fibers were produced using electrostatic spinning process ...
Application of gold nanoparticles–epoxy surface nanocomposites for controlling hotspot density on a large surface area for SERS applications
(Elsevier, 2021-10-01)
The applicability of a novel gold–epoxysurface nanocomposite for surface-enhanced Raman scattering (SERS) is investigated. The nanocomposite consists of ellipsoidal nanoparticles in a hexagonal arrangement, where the average ...
