Magnetic observations at Geophysical Observatory Paratunka IKIR FEB RAS: tasks, possibilities and future prospects

E3S Web of Conferences, 2017
Continuous magnetic measurements at Geophysical Observatory “Paratunka” (PET) of IKIR FEB RAS are performed since 1967. In the new millennium analogue magnetometers were modernized to digital, the technologies of absolute observations were changed, the ...

Magnetic Field‐Modulated Boolean Logic in Proteinoid‐ Fe3 O4 Hybrid Materials

Advanced Physics Research, EarlyView.
Proteinoid‐Fe3O4${\rm Fe}_3{\rm O}_4$. nanoparticle composites exhibit spontaneous electrical oscillations that emulate Boolean logic gates (AND, OR, XOR, NAND, NOR, NOT) under magnetic field modulation. External fields of 65.103 mT tune oscillatory behavior: 84 mT enhances amplitude while 103 mT suppresses it.

Supercritical Carbon Dioxide‐Assisted Interface Formation of LaAlO3/SrTiO3 for Room‐Temperature Ferromagnetism

Advanced Physics Research, EarlyView.
This work pioneers a non‐invasive route for strain engineering of quantum states at complex oxide interfaces, making use of supercritical CO2 as a tunable “strain field” to induce room‐temperature ferromagnetism in 3D LaAlO3/SrTiO3 composites. Structural and chemical analyses confirm the magnetism is strictly interfacial and driven by lattice tensile ...

“Hidden” Landscape of Prehistoric Burial Monuments: The Use of Remote Sensing in the Detection of Neolithic Long Barrows in Bohemia (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT Neolithic long barrows are among the earliest monumental structures in Europe, yet in many parts of Central Europe their surface expression has been largely erased by long‐term agricultural activity. This study evaluates the potential of integrated remote sensing approaches for identifying and contextualizing long barrows and associated ...

Multi‐Method Geophysical Surveys Between and Around the Kerlescan and the Manio Megalithic Alignments in Carnac (Morbihan, France)

Archaeological Prospection, EarlyView.
ABSTRACT The Carnac alignments in Morbihan (France) are among the most famous Neolithic sites of the world. Paradoxically, they have benefited little from a thorough renewal of archaeological data over the past century. There are many reasons for this, but it is mainly because the site has been regarded more as a monument to visit and protect than as ...

Electronic Resonance Network Stabilized Crystal Structure in High‐Nickel Cathodes for Lithium‐Ion Batteries

Carbon Energy, EarlyView.
Transition metal (TM) ions with empty eg orbitals induce single‐electron delocalization in Ni3+ to form the resonance structure of Ni─OO─TM through the high‐entropy effect. High‐nickel cathode materials with electron resonance structure have the advantages of improving thermodynamic stability, suppressing phase transitions, and mitigating lattice ...

Pyrrolic‐Nitrogen‐Enriched Aerogels With Magnetic Responsiveness Enable Cooperative Hydrogen‐Bond Regulation for High‐Performance Solar Interfacial Evaporation

Carbon Energy, EarlyView.
A pyrrolic‐nitrogen‐enriched ferromagnetic aerogel enables sophisticated cooperative regulation of hydrogen bonding, whereby this dual‐regulatory mechanism effectively reduces vaporization enthalpy while simultaneously enhancing molecular dynamics. The system demonstrates exceptional self‐cleaning capability and exhibits superior performance in the ...

T½ Tuning in a Synergistic BODIPY‐Tetrazole Fe(II) Spin‐Crossover‐Photoluminescence System via Co‐Ligand Variation

Chemistry – A European Journal, EarlyView.
We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...
