To check on the nature of weak magnetic order in polycrystalline magnetoelectric Pb(Fe1∕2Nb1∕2)O3 X-band, Q-band, and far infrared electron paramagnetic resonance (EPR) spectra have been measured between 4 600K compared with susceptibility magnetization data. The asymmetric line shapes can be simulated at higher temperature by thermally fluctuating superparamagnetic nanoclusters. pronounced dependence position demonstrates presence an internal field which is small but nonzero even room...
The ESR spectra of a ${\mathrm{TDAE}}^{+}\ensuremath{-}{C}_{60}^{\phantom{\rule{0ex}{0ex}}\ensuremath{-}}$ single crystal show the existence antiferromagnetic (AFM) correlations between unpaired spins on neighboring ${C}_{60}^{\phantom{\rule{0ex}{0ex}}\ensuremath{-}}$ ions along c axis and spin canting which leads, below ${T}_{c}$, to weak ferromagnetism direction perpendicular axis. This suggests that Dzyaloshinsky-Moriya type mechanism is responsible for ferromagnetic ordering rather than...
Nuclear Quadrupole Resonance (NQR) spectroscopy has been known for 70 years. It is suitable the study of measured (poly)crystalline chemical compounds containing quadrupole nuclei (nuclei with spin I ≥ 1) where characteristic NQR frequencies represent fingerprints these compounds. In several cases, 14N can distinguish between polymorphic crystalline phases active pharmaceutical ingredients (APIs). order to further stimulate studies, we review here results API polymorphism studies obtained in...
The participation of stakeholders in the planning protected natural areas is growing significantly.It enhances their trust protection aims and management measures.Limited time finances, however, often reduce impact stakeholder on level information education, thus usually resulting insufficient implementation choices regarding nature conservation.The article describes main stages planning, enabling us to determine identity key stakeholders, planned methods used achieve it.Furthermore, a...
A study of the microstructures and magnetic properties nanosize Zn ferrite (ZnFe2O4), Mn (MnFe2O4), cation deficit Zn–Mn ferrites Zn0.70Mn0.23Fe1.89O4 (S1), Zn0.41Mn0.50Fe1.84O4 (S2) Zn0.18Mn0.67Fe1.85O4 (S3) was performed. The crystallite size for all samples determined by x-ray powder diffraction (XRPD) analysis using four different methods, close to particle found from transmission electron microphotography. Among methods XRPD line broadening it seems that cubic harmonic function method...
The authors show that a combination of proton-nitrogen level crossing polarization transfer with pulsed spin-locking sequence makes N14 nuclear quadrupole resonance (NQR) fast and sensitive enough to be used in routine explosive detection as well the pharmaceutical industry for nondestructive chemical analysis solid samples polymorph determination. As an example we present “single shot” measurements NQR spectra 15g trinitrotoluene at room temperature total measuring time 20s.
Close-to-nature urban forests and remnants of natural vegetation represent an important opportunity for residents to experience daily perception access the environment. Despite there being a high percentage forest cover (59%) favorable structure prevailing forested landscapes in Slovenia, expansion infrastructure-driven development has severely weakened connectivity conservation suburban forests. The majority settlements lie within walking distance surrounding (<1 km). However, only...
Combination of proton-nitrogen level crossing polarization transfer and pulsed spin-locking sequence makes N14 nuclear quadrupole resonance (NQR) in trinitrotoluene fast sensitive enough to be used routine detection explosives. Enhancement factors for all three NQR lines (the case with η≠0) were calculated compared experimental values. Good agreement between measured signal enhancement was observed. signals a 15g sample predominantly monoclinic modification 15s different magnetic fields. The...
