Antiferromagnetic phase in the highly H-doped LaFeAsO has been investigated by neutron powder diffraction at J-PARC MLF. The characteristic antiferromagnetic structure, the structural phase transition immediately above TN, and the established phase diagram are discussed. Measurements with multiprobe of muon, neutron,…
TonB dependent transporters are a family of proteins that is essential for the success of many pathogenic bacteria, making these interesting targets for new antibiotics. TonB coupling to these proteins allows utilization of the proton-motive force of the inner membrane through a mechanism not yet fully understood. The…
Předkládaná diplomová práce se věnuje separaci předložených pH senzitivních konjugátů antituberkulotika isoniazidu s blokovým kopolymerem alfa-methoxy-poly(ethylenglykol)-bpoly(L-lysinem).

Rubidium Iodide crystals are bcc in structure. Study about RbI crystal in present of two body body interaction has been observed some shortcomings especially with respect to the Cauchy violation, high dielectric constants, high electronic polarizabilities and phonon dispersion relation because of lack of many body ter…

As an example for industrial applications of neutron techniques, we report the result of our catalytically-active-site analysis with powder neutron diffraction for tantalum-oxide-based oxygen reduction electrocatalysts, which are expected to be used for future fuel-cell powered vehicles. Owing to the higher sensitivit…
In the present study, we have synthesised carbon nanoparticles (CNPs) through a relatively simple process using a hydrocarbon precursor. These synthesised CNPs in the form of elongated spherules and/or agglomerates of 30-55 nm were further used as a support to anchor platinum nanoparticles. The broad light absorption…

A stable nanoemulsion consisting of nanometer-sized oil droplets in water having a self-standing capability was prepared by high-pressure emulsification. Rheological measurements show that the nanoemulsion has a high viscosity and a yield stress. Small-angle neutron scattering (SANS) revealed the presence of an ordere…

In this paper, I will report my structural studies for amorphous and nano-crystalline materials by taking advantage of neutron diffraction. Recently, the three dimensional atomic arrangements obtained by reverse Monte Carlo modeling based on neutron and X-ray diffraction data informed us of the precise structural feat…
We study the cyclic sequences induced at in nity by pairwise-disjoint colored rays with apices on a given bal- anced bichromatic point set, where the color of a ray is inherited from the color of its apex. We derive a lower bound on the number of color sequences that can be realized from any xed point set. We also exa…
Effects of vacumm annealing time on the microstructure,mechanical and soft magnetic properties of FeCo-2V-0.5Cr alloy have been investigated.After annealed at 800℃for about 2h,the alloy can obtain the optimal tensile strength and elongation while remaining good soft magnetic property,the tensile strength and elongatio…
Spin fluctuations of iron-based superconductors are studied using unpolarized and polarized inelastic neutron scattering technique. Remarkable enhancement of magnetic signal at a specific energy is observed in superconducting phase, which is so called spin resonance. The spin resonance exhibits c-axis and spin-space a…
In order to overcome low flux of neutron sources as well as weak diffraction intensity from bio-macromolecule crystals, several devices have been developed in neutron biological crystallography. Elastically bent Si monochromator has contributed the increase of incident beam intensity, and neutron imaging plate (NIP) h…
When a liquid is supercooled towards the glass transition,its dynamics drastically slows down,whereas its static structure remains relatively unchanged.Finding a structural signature of the dynamic slowing-down is a major challenge,yet it is often too subtle to be uncovered.Here we discovered the...
ZnO materials with different micro/nanoscale morphologies (needle-like, rods, flower-like and spheroidal) were preparedby different techniques. Gold was loaded (1% wt.) on the ZnO supports through a double impregnation method. Themorphology of the ZnO and Au/ZnO materials was analyzed by scanning electron microscopy (…

Microstructure evolution during thermo-mechanically controlled processing for steels has been studied using in situ neutron diffraction. Time-sliced data on phase transformation kinetic, texture change, internal stresses, and dislocation density can be obtained for the development of advanced steels.
