Crustal rocks have a magnetic memory that may endure for millions or even billions of years due to composition of iron oxides The secret behind that permanence lies in the high temperatures to which the minerals were exposed near their Curie temperatures of several hundred degrees Celsius while cooling in Earth rsquo s magnetic field and in the ...

Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Decoding High‐voltage LiCoO2: From Degradation to Stabilization Toward Durable Li‐ion Batteries
This review systematically addresses the degradation mechanisms and stabilization strategies for high‐voltage LiCoO2 cathodes. Key enhancement approaches including foreign‐ion doping, surface modifications, structural design, and electrolyte optimization are critically assessed.

Multiply remagnetized Silurian carbonate sequence in Estonia [PDF]
Palaeomagnetic studies were carried out on Silurian sedimentary rocks of Estonia. The studied sequence (126 samples from 4 localities) is composed of Silurian lime- and dolostones of Llandovery and Wenlock age (444–423 Ma).

Interphase Self‐Optimization Enables Stable Magnesium Anode in Hydrogel Electrolyte
Based on a MgCl2 hydrogel electrolyte, we identify a tridentate chelant additive to construct a magnesium oxychloride interphase on Mg metal anodes. This self‐optimized interphase enables low‐resistance Mg2+ stripping/plating, resulting in much elongated cycling life of 600 h with 0.24 V nucleation overpotential.

Paleointensity Estimates From Ignimbrites: The Bishop Tuff Revisited
Volcanic ash flow tuffs (ignimbrites) may contain single domain‐sized (titano) magnetite that should be good for recording geomagnetic field intensity, but due to their complex thermal histories also contain other magnetic grains, which can complicate ...

A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to
