Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

Advanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Orbital Magnetic Moment Controlled Converse Magnetoelectric Effect in bcc‐Co3Mn/Fe/V/PMN‐PT Multiferroic Heterostructures

Advanced Science, EarlyView.
Based on orbital magnetic moment control, a material design strategy is proposed for a giant converse magnetoelectric effect in multiferroic heterostructures. This study will pioneer a promising route toward low‐power spintronic devices with an electric field.

Robust Magnetic Attitude Control of Satellites

IEEE/ASME Transactions on Mechatronics, 2013
Magnetic torquers are frequently adopted as primary actuators for the attitude control of small satellites in low Earth orbit. Such actuators generate a magnetic dipole which, in turn, leads to control torques thanks to the interaction with the magnetic field of the Earth.

Magnetic attitude control of a spinning satellite

1st Annual Meeting, 1964
Design of a self-contained magnetic attitude control system for a spinning satellite is described, and particular control techniques for sensing and actuation are developed. A specific control problem associated with the alignment of spin axis normal to the orbit plane in the presence of external perturbations is examined in detail, and a simple ...

Analysis of Satellite Magnetic Data

Exploration Geophysics, 2005
Night-time measurements of the Earth?s undisturbed, quiet magnetic field at satellite altitudes provide models of the main field and its secular variation, and of the crustal magnetic anomaly field. Fields from the regular daily variations of solar and lunar origin are most pronounced in daytime data and can affect aeromagnetic and ground magnetic ...

Magnetic satellites in mictomagnetic CuMn

Journal of Physics F: Metal Physics, 1983
The neutron scattering intensities about the 11/20 diffuse peak, in 15 and 40 at.% CuMn single crystals have been investigated. It is suggested that the maxima in the diffuse magnetic scattering intensity, which occurs at 1, 1+or- delta ', 0 type positions, is caused by an interaction with the conduction electrons.
