Magnetic declination of the territory of Ukraine: the results of observations and calculations

Геофизический журнал, 2015
A technology is proposed for calculating the strength and angular components of the vector of the induction of the Earth's magnetic field. The technology is based on the development of a three-dimensional model of the earth's crust and the calculation of

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

Advanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

The Earth's Magnetic Field

Eos, Transactions American Geophysical Union, 2000
The study of the Earth's magnetic field is one of the oldest scientific disciplines. Research in geomagnetism enabled information to be deduced about the Earth's interior, the electrodynamics of the upper atmosphere at altitudes above 100 km, and the processes at work in interplanetary space and even on the surface of the Sun.Regular recordings of the ...

Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

Advanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.
