A study of helium-3 nuclear magnetic relaxation mechanism in contact with 20 nm DyF nanoparticles.

The spin kinetics of adsorbed and liquid He in contact with a mixture of LaF (99.67 %) and DyF (0.33 %) 20 nm powders at temperatures of 1.

Microporous Block Copolymers Modified with Cu(II)-Coordinated Polyethylene Oxide-Substituted Silicas for Analytical Sensors.

The influence of stable-to-self-condensation Cu(II)-coordinated polyoxyethylene-substituted silicas (ASiP-Cu-0.5) on the synthesis of microporous block copolymers (OBCs) whose structural feature is the existence of coplanar polyisocyanate blocks of acetal nature (O-polyisocyanates) and a flexible-chain component of amphiphilic nature was studied. The use of ASiP-Cu-0.

Diffusion Anisotropy of Gaseous Helium-3 in Ordered Aerogels at Low Temperatures.

We report on the first observation of diffusion anisotropy of gaseous helium-3 entrapped in ordered aerogels at 4.2 K. The origins of He diffusion anisotropy in aerogels of different porosity are discussed.

TheHe nuclear magnetic relaxation in nematically ordered AlOaerogels: effects ofHe and nitrogen pre-plating.

The results ofHe gas pulsed NMR spin-lattice relaxation study in high-porosity (84.9%-97.9%) nematically ordered AlOaerogels at 1.

Anisotropic reduced diffusion in dilute liquid He-He mixture in ordered aerogel.

We report on the first observation of He diffusion anisotropy in He-He liquid mixture confined in ordered aerogels at 1.5-4.2 K temperatures.
