Acidity and the multiphase chemistry of atmospheric aqueous particles and clouds

The acidity of aqueous atmospheric solutions is a key parameter driving both the partitioning of semi-volatile acidic and basic trace gases and their aqueous-phase chemistry. In addition, the acidity of atmospheric aqueous phases, e.g., deliquesced aerosol ...

Three-dimensional radiative transfer effects on airborne and ground-based trace gas remote sensing

Alexis Berne, Dominik Brunner, Thomas Wagner

Air mass factors (AMFs) are used in passive trace gas remote sensing for converting slant column densities (SCDs) to vertical column densities (VCDs). AMFs are traditionally computed with 1D radiative transfer models assuming horizontally homogeneous condi ...

Upgrade of a low-temperature scanning tunneling microscope for electron-spin resonance

Harald Brune, François Patthey, Nicolas Weiss, Donat Fabian Natterer, Tobias Bilgeri, Patrick Robert Forrester

Electron spin resonance with a scanning tunneling microscope (ESR-STM) combines the high energy resolution of spin resonance spectroscopy with the atomic scale control and spatial resolution of STM. Here we describe the upgrade of a helium-3 STM with a 2D ...

Performance of ceramic anvils for high pressure neutron scattering

Livia Eleonora Bove Kado

Three kinds of ceramics, zirconia-toughened alumina (ZTA), alumina-toughened zirconia (ATZ) and yttria-stabilized zirconia (YSZ), were tested as anvil materials, mainly for the purpose of neutron scattering study under high pressure. ZTA with non-toroidal ...

Extreme light absorption in a necking-free monolayer of resonant-size nanoparticles for photoelectrochemical cells

Ali Dabirian

Semiconductor photoelectrodes for water oxidation that absorb visible light usually have poor electronic transport properties and small optical absorption coefficients near their absorption edge. Therefore, innovative designs that lead to significant optic ...

Measurement of acoustic attenuation in South Pole ice

Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

Using the South Pole Acoustic Test Setup (SPATS) and a retrievable transmitter deployed in holes drilled for the IceCube experiment, we have measured the attenuation of acoustic signals by South Pole ice at depths between 190 m and 500 m. Three data sets, ...

Rock damage control in bedrock blasting excavation for a nuclear power plant

Jian Zhao

Drill and blast is a major method for bed rock excavation in nuclear power plant engineering. Under blasting excavation, blast-induced vibration propagates in rock mass and induces damage to surrounding rock. Studying the characteristics of wave propagatio ...

A Multiband Concurrent Sampling based RF Front End for Biotelemetry Applications

Christian Enz, Aravind Prasad Heragu Singaiyengar

A sub-sampling based multiband RF front end suitable for medical telemetry applications is presented. Using a single inductor and a single sampling frequency it is shown how to downconvert concurrently Bluetooth LE and MICS band signals to baseband with re ...

Diffusion-Weighted Spectroscopy: A Novel Approach to Determine Macromolecule Resonances in Short-Echo Time H-1-MRS

Rolf Gruetter, Cristina Ramona Cudalbu, Nicolas Kunz

Quantification of short-echo time proton magnetic resonance spectroscopy results in >18 metabolite concentrations (neurochemical profile). Their quantification accuracy depends on the assessment of the contribution of macromolecule (MM) resonances, previou ...

Effects of upstream hydropower operation and oligotrophication on the light regime of a turbid peri-alpine lake

Alfred Johny Wüest

Anthropogenic activities in catchments can alter the light regimes in downstream natural waters, affecting light attenuation and the perceived optical properties of the waters. We analyzed the effects of upstream hydropower operation and oligotrophication ...
