Br diffusion in molten NaBr explored by coherent quasielastic neutron scattering.

Physical review. E

Demmel F, Alcaraz O, Trullas J.
PMID: 27176349
Phys Rev E. 2016 Apr;93:042604. doi: 10.1103/PhysRevE.93.042604. Epub 2016 Apr 12.

Molten sodium bromide has been investigated by quasielastic neutron scattering focusing on the wave vector range around the first structure factor peak. The linewidth of the scattering function shows a narrowing around the wave number of the structure factor...

Lee J, Tymchenko M, Argyropoulos C, Chen PY, Lu F, Demmerle F, Boehm G, Amann MC, Alù A, Belkin MA.
PMID: 24990746
Nature. 2014 Jul 03;511(7507):65-9. doi: 10.1038/nature13455.

Intersubband transitions in n-doped multi-quantum-well semiconductor heterostructures make it possible to engineer one of the largest known nonlinear optical responses in condensed matter systems--but this nonlinear response is limited to light with electric field polarized normal to the semiconductor...

Polydopamine Films from the Forgotten Air/Water Interface.

The journal of physical chemistry letters

Ponzio F, Payamyar P, Schneider A, Winterhalter M, Bour J, Addiego F, Krafft MP, Hemmerle J, Ball V.

The formation of polydopamine under mild oxidation conditions from dopamine solutions with mechanical agitation leads to the formation of films that can functionalize all kinds of materials. In the absence of stirring of the solution, we report the formation...

Characterization of the mineral content of a physical sunscreen emulsion and its distribution onto human stratum corneum.

International journal of cosmetic science

Dussert AS, Gooris E, Hemmerle J.
PMID: 18507639
Int J Cosmet Sci. 1997 Jun;19(3):119-29. doi: 10.1046/j.1467-2494.1997.171707.x.

When using physical sunscreens, protection and aesthetic aspects are directly related to particle size and mineral distribution onto skin. These investigations aimed to characterize the different mineral raw materials entering into the composition of a specific sunscreen emulsion and...

Temperature dependent next-neighbour dynamics of liquid lead.

Journal of physics. Condensed matter : an Institute of Physics journal

Demmel F, Howells WS, Morkel C.
PMID: 21694287

Orphan Spins in the S=5/2 Antiferromagnet CaFe_{2}O_{4}.

Physical review letters

Stock C, Rodriguez EE, Lee N, Demmel F, Fouquet P, Laver M, Niedermayer C, Su Y, Nemkovski K, Green MA, Rodriguez-Rivera JA, Kim JW, Zhang L, Cheong SW.
PMID: 29303328
Phys Rev Lett. 2017 Dec 22;119(25):257204. doi: 10.1103/PhysRevLett.119.257204. Epub 2017 Dec 22.

CaFe_{2}O_{4} is an anisotropic S=5/2 antiferromagnet with two competing A (↑↑↓↓) and B (↑↓↑↓) magnetic order parameters separated by static antiphase boundaries at low temperatures. Neutron diffraction and bulk susceptibility measurements, show that the spins near these boundaries are...

Dynamics on next-neighbour distances in liquid and undercooled gallium.

Journal of physics. Condensed matter : an Institute of Physics journal

Demmel F.
PMID: 30431024
J Phys Condens Matter. 2018 Dec 12;30(49):495102. doi: 10.1088/1361-648X/aaeb72. Epub 2018 Nov 15.

Density fluctuations of liquid and 20 K undercooled gallium have been studied by neutron spectroscopy. The decay of density fluctuations has been recorded at the structure factor maximum over a wide temperature range up to twice the melting temperature....

Attractive Interaction between Fully Charged Lipid Bilayers in a Strongly Confined Geometry.

The journal of physical chemistry letters

Mukhina T, Hemmerle A, Rondelli V, Gerelli Y, Fragneto G, Daillant J, Charitat T.
PMID: 31679335

We investigate the interaction between highly charged lipid bilayers in the presence of monovalent counterions. Neutron and X-ray reflectivity experiments show that the water layer between like-charged bilayers is thinner than for zwitterionic lipids, demonstrating the existence of counterintuitive...

Stretchable nanocomposite conductors are essential for engineering of bio-inspired deformable electronics, human-machine interfaces, and energy storage devices. While the effect of strain on conductivity for stretchable conductors has been thoroughly investigated, the strain dependence of multiple other electrical-transport processes...
