Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Behavior of Earth Magnetosphere Radius during Strong Geomagnetic Storms

open access: yesIraqi Journal of Physics, 2019
Magnetosphere is a region of space surrounding Earth magnetic field, the formation of magnetosphere depends on many parameters such as; surface magnetic field of the planet, an ionized plasma stream (solar wind) and the ionization of the planetary upper

Modelling the Earth's magnetic field with magnetometer data from a Raspberry Pi on board the ISS [PDF]

open access: yesarXiv, 2021
We used data from a magnetometer on board the ISS to simulate the Earth's magnetic field. For that purpose, we generated two models from the data and compared them: an off-centered dipole model and a centered multipolar model. We found out that measuring the magnetic field along only two orbits is not enough to provide a good estimate of the Earth's ...

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Defects in Inorganic Mechanoluminescent Phosphors: Insights and Impacts

open access: yesAdvanced Functional Materials, EarlyView.
Mechanoluminescence is attracting more attention recently, and defect dominates mechanoluminescence performances. Investigating how defects work in the mechanoluminescence process is crucial for elucidating its complex luminescence mechanism. This review aims to emphasize the fundamental role of defects in mechanoluminescence, which offers an ...

Finding reconnection lines and flux rope axes via local coordinates in global ion-kinetic magnetospheric simulations [PDF]

open access: yesAnnales Geophysicae
Magnetic reconnection is a crucially important process for energy conversion in plasma physics, with the substorm cycle of Earth's magnetosphere and solar flares being prime examples.

Aircraft attitude measurement using a vector magnetometer [PDF]

open access: yes
The feasibility of a vector magnetometer system was investigated by developing a technique to determine attitude given magnetic field components. Sample calculations are then made using the earth's magnetic field data acquired during actual flight ...

Ambient‐Dried MOF/Cellulose‐Based Aerogels for Atmospheric Water Harvesting and Sustainable Water Management in Agriculture

open access: yesAdvanced Functional Materials, EarlyView.
Ambient‐dried composite aerogels integrating MOF‐303, TEMPO‐oxidized cellulose nanofibers (TOCNF), and hygroscopic salts enable high‐performance atmospheric water harvesting (AWH), achieving competitive uptake at both low and high humidity. Enhanced with a solar‐evaporation layer, these scalable aerogels support self‐sustained plant growth in a ...

THE INFLUENCE OF CERTAIN FACTORS ON THE QUALITY OF GEOMAGNETIC MEASUREMENTS

open access: yesRudarsko-geološko-naftni Zbornik, 1998
The advanced design technology improved the sensitivity of the Earth's Magnetic field measuring instruments. Hence it is possible to measure also the lower intensity values of the Earth's Magnetic field, however then the number of different factors which

Modulating Oxide‐Based Quantum Materials by Ion Implantation

open access: yesAdvanced Functional Materials, EarlyView.
This review highlights how ion implantation, a well developed chip‐technology, enables targeted modulation of oxide‐based quantum materials. This includes tuning of metal‐insulator transitions, magnetism, and superconductivity through selective doping, defect creation, and induced lattice strain. Abstract Ion implantation has emerged as a powerful tool
