Biomechanics at the workplace under hypogravity conditions

The main goal of my research is to establish guidelines for workplace design based on human biomechanics: specifically sitting workplaces and handling areas in 1/6G-1/3G (Moon, Mars) conditions. Such a workplace could be used in long-term space missions in ...

Annual cycle observations of aerosols capable of ice formation in central Arctic clouds

Julia Schmale, Ivo Fabio Beck

The Arctic is warming faster than anywhere else on Earth, prompting glacial melt, permafrost thaw, and sea ice decline. These severe consequences induce feedbacks that contribute to amplified warming, affecting weather and climate globally. Aerosols and cl ...

The vertical structure of precipitation at two stations in East Antarctica derived from micro rain radars

Alexis Berne, Jacopo Grazioli

Precipitation over Antarctica is the main term in the surface mass balance of the Antarctic ice sheet, which is crucial for the future evolution of the sea level worldwide. Precipitation, however, remains poorly documented and understood mainly because of ...

Enhancing the Stability of Porphyrin Dye-Sensitized Solar Cells by Manipulation of Electrolyte Additives

Michael Graetzel, Paul Joseph Dyson, Shaik Mohammed Zakeeruddin, Chenyi Yi, Hoi Nok Tsao, Pui Shan Genevieve Lau

The use of porphyrin-based photosensitizers with superior light-harvesting properties has enabled the power conversion efficiency of dye-sensitized solar cells (DSCs) to reach 13% under full sun illumination. However, a major limitation of such devices cor ...

Cross-Intersecting Families of Vectors

János Pach, Gábor Tardos

Given a sequence of positive integers , let denote the family of all sequences of positive integers such that for all . Two families of sequences (or vectors), , are said to be -cross-intersecting if no matter how we select and , there are at least distinc ...

Detection and reconstruction of large-scale coherent flow structures in gravel-bed rivers

Ulrich Lemmin, Mário Jorge Rodrigues Pereira Da Franca

Large-scale flow structures (LSFS) in the streamwise direction are important features of gravel-bed river flows, because they may contribute to sediment transport and gas exchange. In the present study, these structures are detected using Huang's empirical ...

GNSS-based Orbital Filter for Earth Moon Transfer Orbits

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano

Numerous applications, not only Earth-based, but also space-based, have strengthened the interest of the international scientific community in using Global Navigation Satellite Systems (GNSSs) as navigation systems for space missions that require good accu ...

Observation of the cosmic-ray shadow of the Moon with IceCube

Shirit Cohen, Mathieu Ribordy, Matthias Wolf, Xiaoxia Bai

We report on the observation of a significant deficit of cosmic rays from the direction of the Moon with the IceCube detector. The study of this "Moon shadow" is used to characterize the angular resolution and absolute pointing capabilities of the detector ...

Ion cyclotron resonance heating with consistent finite orbit widths and anisotropic equilibria

Wilfred Anthony Cooper, Jonathan Graves, Martin Jucker

Minority ion cyclotron resonance heating is studied using the self-consistent numerical model SCENIC. This model includes 3D geometries with full shaping and anisotropic pressure effects, warm contributions to the dielectric tensor and full orbit effects. ...

Application of Cu(II) and Zn(II) coproporphyrins as sensitizers for thin film dye sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Mingkui Wang, Pascal Comte, Joël Teuscher, Davide Di Censo, Leila Alibabaei

We synthesized the Cu(II) and Zn(II) complexes of the 2,7,12,17-tetrapropionic acid of 3,8,13,18-tetramethyl-21H,23H porphyrin (coproporphyrin-I) and successfully employed them as sensitizers in dye-sensitized solar cells. Copper(II) coproporphyrin-I exhib ...

Employ a bisthienothiophene linker to construct an organic chromophore for efficient and stable dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Peng Wang, Yu Bai, Sophie Wenger

We employed the bisthienothiophene conjugated linker along with a hydrophobic triphenylamine electron-donor and a hydrophilic cyanoacrylic acid electron-acceptor to construct a high molar extinction coefficient organic photosensitizer, exhibiting a power c ...
