The results of an experimental investigation of electrons colliding with a set of biomolecules that are assumed to be analogues of the building blocks of DNA (furan, 3- hydroxytetrahydrofuran and pyrimidine) and proteins (formamide, N-methylformamide) are presented. Absolute differential cross sections at medium incid…
We have studied the chemical polishing of the surface of single crystals of PbTe and Pb1 − x Sn x Te solid solutions by H2O2-HBr-C2H2O4 bromine-releasing etchants. The dissolution rate of the crystals has been determined as a function of etchant composition, solution stirring rate, and temperature. The polished surfac…
It has long been believed that coexistence among ferromagnetic ordering, superconductivity or heavy-fermion behaviour is impossible, as the former supports parallel spin alignment while the latter two phenomena assume a spin-singlet configuration. This understanding has recently been challenged by a number of observat…
In order to study the phase diagram from a microscopic viewpoint, we have measured wTF- and ZF- μ + SR spectra for the Sr 1- x Ca x Co 2 P 2 powder samples with x = 0, 0.2, 0.4, 0.5, 0.6, 0.8, and 1. Due to a characteristic time window and spatial resolution of μ + SR, the obtained phase diagram was found to be rather…
We have studied the photochromic reaction of the diarylethene derivative on Au nanoparticles using the incoherent excitation as a function of the wavelength of the irradiation light with the aim to clarify the effect of metal nanoparticles on the reaction yield. The photochemical reaction was suppressed by the Au nano…
Graphite powder was mixed with polyurethane in order to prepare composite materials in different proportions intended to be used in voltammetric analysis. Results of thermogravimetry, differential scanning calorimetry and dynamical mechanical analysis were used in the characterization of the composites. Thermal and vi…
Using a phenomenological free‐energy density expansion, in this work, we have studied the effects of temperature and electric field on the spontaneous polarization of antiferroelectric B2 phase in the vicinity of I–B2 phase transition in a bent-core mesogen 12OSOR. The free-energy density of the system is written in t…
μ SR and ALCR techniques have been used to investigate the structure and dynamics of the Mu-cyclohexadienyl radical interacting with Au and Pt metal nanoparticles (MNPs) supported in mesoporous silica (SBA-15). Surprisingly, coherent precession signals are observed and the isotropic hyperfine coupling constants are al…
We report the first transverse, longitudinal and zero field measurements performed on Vanadium Dioxide (VO 2 ) where we find a significant local magnetic field below T = 34.7 ± 0.16 K at the muon site and Mu d motion above 340 K. Distinct shifts in the muon relaxation rates and Kubo-Toyabe delta parameters, near the m…
We synthesized BiPO4:Tb3+ nanowires by the hydrothermal process. The synthesized nanoparticles were measured using XRD, SEM, and luminescence spectrophotometry. The XRD patterns and SEM images indicate that reaction time induces phase changes but has no obvious influence on size and morphology. All samples show charac…
Plasma during Electrolytic Oxidation (PEO) of magnesium-aluminium alloys is studied in this work by means of Optical Emission Spectroscopy (OES). Spectral line shapes of the H β , Al II 704.21 nm and Mg II 448.11 nm line are analyzed to measure plasma electron number density N e . From the H β line profile, two PEO pr…
The paper discusses structure investigations of the zirconium oxide-multiwalled carbon nanotube composite produced by electrophoretic codeposition of the components. Thermal analysis, Raman spectroscopy, and TEM analysis have revealed the strong influence of multiwalled carbon nanotubes on the sintering kinetics of zi…
In the present study, a nitrogen atmospheric pressure plasma jet (APPJ) was used for irradiation of oral cancer cells. Since cancer cells are very susceptible to plasma treatment, they can be used as a tool for detection of APPJ-effective areas, which extended much further than the visible part of the APPJ. An immunof…
Due to its anticuprate Ti 2 O layer and its fascinating phase diagram with a large coexistence area of superconductivity and a density wave phase, the new class of titanium based superconductors attracts great scientific interest. In this paper we report μSR investigation on powder samples of Ba 1-x Na x Ti 2 Sb 2 O (…
We report detailed behaviour of low energy 8 Li implanted near the surface of α- Al 2 O 3 single crystal, as revealed by beta-detected NQR of 8 Li. We find that the implanted 8 Li occupies at least two sites with non-cubic symmetry in the Al 2 O 3 lattice. In both sites the 8 Li experiences axially symmetric electric…
Anisotropic sensitivity is related to the different intermolecular steric arrangements across the slip plane induced by shock compression along various orientations.
The effect of dopant atoms on the structural and elastic properties of α titanium is examined through the use of density functional theory. The effect of 66 dopant atoms, from H through the third row transition metal elements, were considered in this study. In all cases the dopant concentration was approximately 3 at%…
In order to elucidate the magnetic nature for a novel one-dimensional zigzag chain compound, NaCr 2 O 4 , we have measured μ + SR spectra using a powder sample in the temperature range between 2 and 200 K. Weak transverse field (wTF-) μ + SR measurements indicated that the whole volume of the sample enters into an ant…
ABSTRACT Here, we report on the synthesis and different crystallization behavior of linear‐ and star‐ PCL's containing a photocleavable linker (5‐hydroxy‐2‐nitro benzaldehyde), modulated by photochemical switching. Basis is the attachment of a photocleavable moiety close to the star‐core of a three‐arm star poly(capro…
Batch culture of Azohydromonas lata was investigated for the production of intracellular poly-β-hydroxybutyrate (PHB). In order to determine the C:N value of the culture media for maximizing the microbial productivity of PHB, different concentrations of glucose and ammonium chloride were used as carbon and nitrogen so…
