materials and is characterized by the absence of a stuffing box (0-ring). This is a real innovation since a flexible seal between the valve body and the needle stem is a source of many problems: leaks, pollution ... presses with helium at a pressure ranging from 100 to 2 kbar (0.2 GPa). The gas is compressed with a standard single-stage diaphragm ...

within the soap particles. To test its properties, the team introduced a magnet to a test tube containing their new soap lying beneath a less dense organic solution. When the magnet was introduced the iron-rich ... spills at sea. Scientists from Bristol University have developed a soap, composed of iron rich salts dissolved in water, that responds ...

arrangement of polymer micelles with a diameter of about 180 Å close to a hydrophilic and a hydrophobic coated silicon wafer. For the top panels the sample is in a liquid phase. The ring of increased intensity ... sample in a crystalline cubic phase. Close to the hydrophilic interface a cubic close packed structure is formed whereas close to the ...

must be identified with a spokesperson, who should be affiliated to a scientific institution of an ILL member country. The implementation of an LTP requires yearly reports and a final report. LTPs can be ... long-term beamtime, by submitting a Long Term Proposal (LTP). The ILL Scientific Council and ILL Management believe that LTPs can be ...

lattice of spins is called a magnon, while a similar excitation of the atom lattice is known as a phonon. Phonons and magnons can be conveniently observed with the help of a neutron three-axis spectrometer ... Yannick Raoul. ©2013-2018 Institut Laue-Langevin. Magnons is a 3D animation demonstrating the interaction of a neutron with the atomic spins ...

working on the 3 He polariser. A series of cells are filled with 0.7 mbar of pure 3 He atoms. The discharge applied in the cells put the 3 He atoms in a metastable state. A laser light, circularly polarised ... with the polarised gas under a pressure of several atmospheres. The polarisation remains for a long duration inside the bottle. With the ...

Scattering (CEνNS) - pronounced “sevens” - a low energy process (< 50 MeV) where a neutrino smacks a nucleus via exchange of a Z boson, and the nucleus recoils as a whole. This was predicted in 1974 and observed ... Ricochet (LPSC/ILL) - Coherent elastic nuclear scattering of neutrinos A neutrino is a fermion that interacts only via the weak ...

confined to a planar surface making the tetrahedral arrangement impossible. A team of scientists from CEA-IRAMIS in collaboration with the Synchrotron Soleil and the ILL has given this problem a closer look ... mobile or liquid molecules have a strong tendency to cluster forming transient patches. These patches grow and at 220 K percolate, i.e. ...

obtained in this study will help to build a unique scenario for the effects of pressure on protein dynamics. A more rugged energy landscape can clearly have a strong influence on the sub-nanosecond dynamics ... landscape. At temperatures above ~200K, these fluctuations lead to a steep increase in the thermal dependence of all dynamical properties,  ...
