We consider a new configuration for a neutron small angle scattering instrument at the pulsed IBR-2M reactor with a mixed (cold and thermal) moderator system. This system provides added-up spectra from the cold and thermal parts of the moderator. We

Nuclear membranes are prepared by heavy ions irradiation of polymer foils which are subsequently etched by a chemical agent. This allows us to prepare parallel channels with very uniform diameter from a few nm to μm range. Due to their small dispers

In the present work we have demonstrated the broad possibilities of the neutron diffraction method for studying the time-dependent acoustic effects in perfect weak ferromagnet crystals.

The orientation of dimyristoylphosphatidylcholine (DMPC) multilamellar vesicles below and close to the main phase transition and of DMPC/C12E8 mixed micelles in strong magnetic fields has been studied via small-angle neu- tron scattering at magnetic

The neutron and X-ray small angle scattering data obtained from the cyclopalladated 4-dodecyloxy-4-methylazobenzene liquid crystal [(DOMAB)-PdCl]2 are discussed. The results show that this compound forms several different solids whose nature should b

The positional short-range order, SRO ⊥ , perpendicular to the nematic director n has been studied in the fibre-type nematics, n BABAs, by neutron diffraction. SRO ⊥ is found to be dependent on other types of nematic short-range order but not on

The nematic liquid crystals such as MBBA, OH-MBBA, EBBA exhibit a large number of solid phases, e.g., on fast cooling, a frozen state may be formed, and metastable phases are obtainable by annealing. X-ray measurements have been performed to characte

A neutron diffraction method has been developed for studying magnetoacoustic phenomena in weak ferromagnet crystals of high perfection. The method is highly sensitive to both acoustic and magnetic vibrations and enables us to measure the vibration am

Lyotropic Nematics are liquid crystalline mixtures characterized by anisotropic aggregates of amphiphilic molecules with finite shape and long range orientational but no positional order. They are distinguished according to their macroscopic properti
