Advanced optical components for mid-infrared applications

The mid-infrared wavelength range, defined from 2.5 um to 25 um is of a high scientific and technological interest. One of its main application field is in spectroscopy, since these wavelengths coincidewith the fundamental rotational-vibrational modes of m ...

Ultrafast Laser to Tailor Material Properties: An Enabling Tool in Advanced Three-dimensional Micromanufacturing

Yves Bellouard

The progress made in ultrafast laser technology towards high repetition rate systems have opened new opportunities in micromanufacturing. Non-linear absorption phenomena triggered by femtosecond pulses interacting with transparent materials allow material ...

Correcting for photodestruction in super-resolution optical fluctuation imaging

Theo Lasser, Arno Pino Bouwens, Tomas Lukes

Super-resolution optical fluctuation imaging overcomes the diffraction limit by analyzing fluctuations in the fluorophore emission. A key assumption of the imaging is that the fluorophores are independent, though this is invalidated in the presence of phot ...

J1−J2 square-lattice Heisenberg antiferromagnets with 4d1 spins: AMoOPO4Cl (A=K,Rb)

Henrik Moodysson Rønnow, Peter Babkevich

Magnetic properties of AMoOPO4Cl (A=K,Rb) with Mo5+ ions in the 4d1 electronic configuration are investigated by magnetization, heat capacity, and nuclear magnetic resonance (NMR) measurements on single crystals, combined with powder neutron diffraction ex ...

An in-situ synchrotron study on microplastic flow of electrodeposited nanocrystalline nickel

Helena Van Swygenhoven, Steven Van Petegem

Deformation in nanocrystalline (NC) materials is strongly influenced by the presence of a large fraction of grain boundaries. We present a comparative study on the role of intragranular root-mean-square strain and crystal-lographic texture on recovery proc ...

Direct protein crystallization on ultrathin membranes for diffraction measurements at X-ray free-electron lasers

Henning Paul-Julius Stahlberg, Christian David

A new era of protein crystallography started when X-ray free-electron lasers (XFELs) came into operation, as these provide an intense source of X-rays that facilitates data collection in the 'iffract-before-destroy' regime. In typical experiments, crystals ...

Single particle maximum likelihood reconstruction from superresolution microscopy images

Suliana Manley, Julia Gunzenhäuser

Point localization superresolution microscopy enables fluorescently tagged molecules to be imaged beyond the optical diffraction limit, reaching single molecule localization precisions down to a few nanometers. For small objects whose sizes are few times t ...

Incommensurate atomic density waves in the high-pressure IVb phase of barium

Gervais Chapuis, Alla Arakcheeva, Philip Pattison, Vladimir Dmitriev

The host–guest structures of elements at high pressure discovered a decade ago still leave many open questions due to the lack of precise models based on full exploitation of the diffraction data. This concerns in particular Ba IV, which is stable in the r ...

Light Scattering Enhancement at the Absorption Edge in Dewetting Droplets of Cyanine Dyes

Frank Nüesch, Jakob Heier, Florent Alexandre Boudoire

Diffraction properties of thin films of dewetted cyanine dye droplets are investigated and related to the complex refractive index. Strong changes in the index of refraction are often found near the absorption edge of organic dyes. Within a small window of ...

Two-dimensional crystallization of the mouse serotonin 5-HT3A receptor

Horst Vogel, Henning Paul-Julius Stahlberg, Ghérici Hassaïne

The mouse serotonin 5-HT3A receptor is a homo-pentameric ligand-gated ion channel (pLGIC) mediating fast excitatory neurotransmission in the central nervous system. The molecular mechanism of ion permeation of 5-HT3A receptors triggered by the neurotransmi ...
