Characteristic rupture height of the mediating air film beneath an impacting drop on atomically smooth mica

Before a droplet can contact a surface during impact, it must first displace the air beneath it. Over a wide range of impact velocities, the droplet first squeezes the air into a thin film, enhancing its resistance to drainage; this slows the progress of t ...

Year-round trace gas measurements in the central Arctic during the MOSAiC expedition

Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot

Despite the key role of the Arctic in the global Earth system, year-round in-situ atmospheric composition observations within the Arctic are sparse and mostly rely on measurements at ground-based coastal stations. Measurements of a suite of in-situ trace g ...

Intrinsic Polarization Super Junctions: Design of Single and Multichannel GaN Structures

Elison de Nazareth Matioli, Luca Nela, Catherine Erine, Amirmohammad Miran Zadeh

Super junctions (SJs) have enabled unprecedented performance in Silicon power devices, which could be further improved by applying this concept to wide bandgap semiconductors like gallium nitride (GaN). Currently, polarization super junctions (PSJs) are th ...

Photophysical and Computational Analysis of a Symmetrical Fluorene-Based Janus Dione Derivative

Alma Rosa Morales Morales

Molecular symmetry plays an important role in the physical characteristics and spectra of a molecule. However, experimental results can sometimes be counterintuitive due to unpredictable properties of a molecule. Photophysical characterization of a centros ...

Ringin' the water bell: dynamic modes of curved fluid sheets

John Martin Kolinski

A water bell is formed by fluid flowing in a thin, coherent sheet in the shape of a bell. Experimentally, a water bell is created via the impact of a cylindrical jet on a flat surface. Its shape is set by the splash angle (the separation angle) of the resu ...

Planck 2013 results. VII. HFI time response and beams

Julien Lesgourgues, Fabio Finelli

This paper characterizes the effective beams, the effective beam window functions and the associated errors for the Planck High Frequency Instrument (HFI) detectors. The effective beam is the angular response including the effect of the optics, detectors, ...

A Full-Scale Particle Image Velocimetry Investigation of “Young” Rotor Blade Tip Vortices

Karen Ann J Mulleners, Kolja Kindler

The blade tip vortex of a full-scale MBB Bo 105 Helicopter is investigated experimentally under simulated hover flight conditions in ground effect by means of stereoscopic Particle Image Velocimetry. Based on the three-component velocity field of azimuthal ...

Combinatorial synthesis of linearly condensed polycyclic compounds, including anthracyclinones, through tandem Diels-Alder additions

Pierre Vogel

Double exocyclic 1,3-dienes such as 2,3,5,6-tetramethylidene-7-oxabicyclo[2.2.1]heptane and its 1-substituted derivatives undergo two successive Diels-Alder additions with large reactivity difference between the addition of the first equivalent (k(1)) and ...

Photodissociation studies of CH3I and CF3I in fluid 4Helium nanodroplets

Andreas Braun

A novel experimental apparatus to study the dynamics of photodissociation and photoionization processes in the interior or at the surface of helium droplets by means of imaging techniques has been designed, built and characterized. This molecular beam mach ...

Imaging the Translational Dynamics of CF3 in Liquid Helium Droplets

Marcel Drabbels, Andreas Braun

The translational dynamics of CF3 in liquid helium have been investigated by photodissociating CF3I dissolved in helium droplets consisting of several thousands of atoms. The velocity distribution of CF3 fragments that have escaped from the droplets has be ...
