PRAXIS is a unique spectrograph which is fed by fibres that remove the OH background and is optimised specifically to benefit from OH-Suppression. The OH suppression is achieved with fibre Bragg gratings, which were tested successfully on the GNOSIS instrument. PRAXIS uses the same fibre Bragg gratings as GNOSIS in its first implementation, and will exploit new, cheaper and more efficient, multicore fibre Bragg gratings in the second implementation. The OH lines are suppressed by a factor of similar to 1000, and the expected increase in the signal-to-noise in the interline regions compared to GNOSIS is a factor of similar to 9 with the GNOSIS gratings and a factor of similar to 17 with the new gratings. PRAXIS will enable the full exploitation of OH suppression for the first time, which was not achieved by GNOSIS (a retrofit to an existing instrument that was not OH-Suppression optimised) due to high thermal emission, low spectrograph transmission and detector noise. PRAXIS has extremely low thermal emission, through the cooling of all significantly emitting parts, including the fore-optics, the fibre Bragg gratings, a long length of fibre, and the fibre slit, and an optical design that minimises leaks of thermal emission from outside the spectrograph. PRAXIS has low detector noise through the use of a Hawaii-2RG detector, and a high throughput through a efficient VPH based spectrograph. PRAXIS will determine the absolute level of the interline continuum and enable observations of individual objects via an IFU. In this paper we give a status update and report on acceptance tests.}, language = {en} } @misc{MazzioThulasimaniRylletal.2018, author = {Mazzio, Katherine A. and Thulasimani, Monika Raja and Ryll, Britta and Kojda, Sandrino Danny and Habicht, Klaus and Raoux, Simone}, title = {Synthetic manipulation of hybrid thermoelectric materials}, series = {Abstracts of papers : joint conference / The Chemical Institute of Cananda, CIC, American Chemical Society, ACS}, volume = {255}, journal = {Abstracts of papers : joint conference / The Chemical Institute of Cananda, CIC, American Chemical Society, ACS}, publisher = {American Chemical Society}, address = {Washington}, issn = {0065-7727}, pages = {1}, year = {2018}, language = {en} } @misc{KochovskiJiaLu2018, author = {Kochovski, Zdravko and Jia, He and Lu, Yan}, title = {Morphological study of microgel-based colloidal systems by cryogenic transmission electron microscopy (cryo-TEM)}, series = {Abstracts of papers : joint conference / The Chemical Institute of Cananda, CIC, American Chemical Society, ACS}, volume = {256}, journal = {Abstracts of papers : joint conference / The Chemical Institute of Cananda, CIC, American Chemical Society, ACS}, publisher = {American Chemical Society}, address = {Washington}, issn = {0065-7727}, pages = {2}, year = {2018}, language = {en} } @misc{Lendlein2018, author = {Lendlein, Andreas}, title = {Fabrication of reprogrammable shape-memory polymer actuators for robotics}, series = {Science robotics}, volume = {3}, journal = {Science robotics}, number = {18}, publisher = {American Assoc. for the Advancement of Science}, address = {Washington}, issn = {2470-9476}, doi = {10.1126/scirobotics.aat9090}, pages = {2}, year = {2018}, abstract = {Shape-memory polymer actuators, whose actuation geometry and switching temperatures are reprogrammable by physical fabrication schemes, were recently suggested for robotics with the option for self-healing and degradability.}, language = {en} } @misc{Santer2018, author = {Santer, Svetlana}, title = {Light responsive soft nano-objects}, series = {Abstracts of papers : joint conference / The Chemical Institute of Cananda, CIC, American Chemical Society, ACS}, volume = {256}, journal = {Abstracts of papers : joint conference / The Chemical Institute of Cananda, CIC, American Chemical Society, ACS}, publisher = {American Chemical Society}, address = {Washington}, issn = {0065-7727}, pages = {1}, year = {2018}, language = {en} } @misc{JayNorellKunnusetal.2018, author = {Jay, Raphael J. and Norell, Jesper and Kunnus, Kristjan and Lundberg, Marcus and Gaffney, Kelly and Wernet, Philippe and Odelius, Michael and F{\"o}hlisch, Alexander}, title = {Dynamcis of local charge densities and metal-ligand covalency in iron complexes from femtosecond resonant inelastic soft X-ray scattering}, series = {Abstracts of Papers of the American Chemical Society}, volume = {256}, journal = {Abstracts of Papers of the American Chemical Society}, publisher = {American Chemical Society}, address = {Washington}, issn = {0065-7727}, url = {http://nbn-resolving.de/urn:nbn:se:uu:diva-370051}, pages = {2}, year = {2018}, language = {en} } @misc{MehrabiSchulzMuellerWerkmeisteretal.2018, author = {Mehrabi, Pedram and Schulz, Eike and M{\"u}ller-Werkmeister, Henrike and Persch, Elke and De Gasparo, Raoul and Diederich, Francois and Tellkamp, Friedjof and Pai, Emil F. and Miller, R.
