Dissipative soliton protocols in semiconductor microcavities at finite temperatures

Hugo Pierre Alexandre Flayac

We consider exciton polaritons in a semiconductor microcavity with a saturable absorber in the growth direction of the heterostructure. This feature promotes additional nonlinear losses of the system with the emergence of bistability of the condensate part ...

Impact of deepwater mixing on hypoxia in Lake Geneva

Alfred Johny Wüest, Damien Bouffard, Robert Vincent Schwefel

Lake Geneva is recovering from its eutrophic past but no significant trend in the areal hypolimnetic oxygen depletion rate has been observed over the last 30 years. Due to the large depth of 309 m, the lake is not mixed completely every winter which can le ...

Nonequilibrium hysteresis and spin relaxation in the mixed-anisotropy dipolar-coupled spin-glass LiHo0.5Er0.5F4

Henrik Moodysson Rønnow, Peter Babkevich, Bastien Dalla Piazza, Julian Piatek, Ivan Kovacevic, Stephen Paul Neithardt

We present a study of the model spin-glass LiHo0.5Er0.5F4 using simultaneous ac susceptibility, magnetization, and magnetocaloric effect measurements along with small angle neutron scattering ( SANS) at sub-Kelvin temperatures. All measured bulk quantities ...

Grain Boundary Relaxation in 18-carat Gold Alloys

Ann-Kathrin Audren

Grain boundaries (GBs) play an important role for the mechanical properties of metals. In addition to dislocation motion inside the grains, some metal alloys deform along the GBs at high temperatures. GBs can also be the cause of a brittle behaviour of som ...

Loading and release of internally self-assembled emulsions embedded in a magnetic hydrogel

László Forró, Andrzej Sienkiewicz, Katarzyna Pierzchala

We have investigated drug loading and release from thermosensitive gel emulsions with external triggering by an alternating magnetic field (AMF) for on-demand drug delivery. Superparamagnetic iron oxide nanoparticles dispersed in gel emulsions were used to ...

Helium embrittlement of a lamellar titanium aluminide

Philippe Spätig, Per Magnusson

Embrittlement by helium was investigated in a lamellar TiAl alloy under two conditions: Specimens were implanted to various amounts of helium up to 762 appm at temperatures from 630 °C to 1000 °C and some of them subsequently creep-tested at the same tempe ...

Heavily deformed 18-carat yellow gold samples show a recrystallization peak at 700 K during the first heating. The mechanical loss spectrum of polycrystals shows a relaxation peak at about 780 K, which is absent in single crystals made from the same alloy. ...

Effect of low-temperature processing on dry film photoresist properties for flexible electronics

Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero

This study presents the mechanical characterization of the dry film photoresist PerMX and its adhesion properties when laminated onto Kapton (R) E (PI) and Melinex (R) ST506 (PET). Additionally, the processing temperature, the adhesion strength, and the ne ...
