Electromagnetic actuator design for distributed stiffness

Jamie Paik, Fabio Zuliani

Origami robots characterized by rigid plates linked together with flexible joints have inherent compliance and large deformations. Their low-profile design and folding mechanical transmissions provide substantial force and torque, especially for wearables ...

The Effects of Planetary and Stellar Parameters on Brittle Lithospheric Thickness

Marie Estelle Solange Violay, Michael Heap

The thicknesss of the brittle lithosphere—the outer portion of a planetary body that fails via fracturing— plays a key role in the geological processes of that body. The properties of both a planet and its host star can influence that thickness, and the po ...

On the effects of fluid pressure variations on rock-mass and fault mechanical behaviour

Corentin Jean-Marie Rémi Noël

In the past 20 years, the growing interest in deep geo-reservoirs for purposes such as carbon storage, waste water disposal, or geothermal energy exploitation have led to large-volume fluid injections into the upper continental crust. These fluid injection ...

Effects of composition and pressure on electronic states of iron in bridgmanite

Philippe Gillet, Arnaud Magrez, Susannah McGregor Dorfman

Electronic states of iron in the lower mantle's dominant mineral, (Mg,Fe,Al)(Fe,Al,Si)O-3 bridgmanite, control physical properties of the mantle including density, elasticity, and electrical and thermal conductivity. However, the determination of electroni ...

Porosity evolution at the brittle-ductile transition in the continental crust: Implications for deep hydro-geothermal circulation

Marie Estelle Solange Violay, Mateo Alejandro Acosta, Michael Heap

Recently, projects have been proposed to engineer deep geothermal reservoirs in the ductile crust. To examine their feasibility, we performed high-temperature (up to 1000 degrees C), high-pressure (130 MPa) triaxial experiments on granite (initially-intact ...

Exploring drift effects in TCV single-null plasmas with the UEDGE code

Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Roberto Maurizio

This paper explores the effects of particle drifts across the magnetic field in TCV single-null plasmas using the two-dimensional edge plasma transport code UEDGE. In particular, it aims to reproduce a double-peaked density target profile, a feature which ...

Chemical Characterisation of Deep Earth Reservoirs

Hélène Marie Piet

Seismic imaging of the internal Earth has emphasized the inhomogeneity of its mantle. This interface layer of nearly 3000 km surrounding the central metallic core conducts heat released from the latter, which played a significant role in shaping the actual ...

Molecular wiring of LiMnPO4 (olivine) by ruthenium(II)-bipyridine complexes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ladislav Kavan

LiMnPO4 (olivine) was surface-modified by two different complexes: Ru-bis(4,4'-diethoxycarbonyl-2,2'-bipyridine)(4,4'-dicarboxylate-2,2'-bipyridine) and Ru-bis(4-carboxylic acid-4'-carboxylate-2,2'-bipyridine)(4,4'-dinonyl-2,2'bipyridine). These complexes ...
