Aligned Permanent Magnet Made in Seconds–An In Situ Diffraction Study

Advanced Electronic Materials
The synthesis of a strontium hexaferrite magnet is studied using in situ synchrotron powder X‐ray diffraction (PXRD) with a 16‐ms time resolution. The precursor material is cold compacted shape‐controlled goethite and strontium carbonate.

Deciphering a New Electrolyte Formulation for Intelligent Modulation of Thermal Runaway to Improve the Safety of Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
Diels‐Alder clicks chemistry addresses thermal runaway in lithium‐ion batteries. A thermoresponsive electrolyte with lithium salt in vinylene carbonate (VC) and 2,5‐dimethylfuran (DMFu) operates at room temperature but undergoes Diels‐Alder reactions at high temperatures, enabling a two‐step safety mechanism: a warning phase at ≈100 °C and complete ...

Marine and freshwater micropearls: biomineralization producing strontium-rich amorphous calcium carbonate inclusions is widespread in the genus Tetraselmis (Chlorophyta)

Biogeosciences, 2018
. Unicellular algae play important roles in the biogeochemical cycles of numerous elements, particularly through the biomineralization capacity of certain species (e.g., coccolithophores greatly contributing to the “organic carbon pump” of the oceans ...

Versatile Green Transfer of Magnetoelectronics with Loss‐Free Performance and High Adhesion for Interactive Electronics

Advanced Functional Materials, EarlyView.
An environmentally friendly transfer printing method of nm‐thick giant magnetoresistive (GMR) sensors is demonstrated. This method, relying on water and biocompatible polyvinyl alcohol (PVA) polymer without the need of complex treatments, allows transferring thin films to a wide range of biological, organic, and inorganic substrates.

Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

Advanced Functional Materials, EarlyView.
By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

Advanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...

Coprecipitation of strontium with marine Ca-Mg carbonates.

GEOCHEMICAL JOURNAL, 1984
Relationship between strontium and magnesium contents of marine calcitic carbonates has been studied. The strontium content of marine skeletal calcites increases with increasing magnesium carbonate content (0 to 20mol%) of the calcites, whereas the strontium content of natural protodolomites decreases with increasing magnesium carbonate content (40 to ...

Supervariate Gel Transforms into Various Biominerals in Salt Solutions

Advanced Functional Materials, EarlyView.
It is revealed that common calcium‐based biominerals can form from a stable, non‐toxic ‘supervariate’ gel. This tunable gel selectively yields calcite or hydroxyapatite in carbonate/phosphate solutions, while CaCl₂ facilitates the formation of dihydrate calcium pyrophosphate, which converts to hydroxyapatite upon drying. These findings provide insights

Facile synthesis of ultrafine and high purity spherical strontium carbonate via gas-liquid reaction

Materials Research Express, 2020
In this work, a simple gas-liquid precipitation reaction was developed to fabricate spherical strontium carbonate (SrCO _3 ) particles using strontium hydroxide (Sr(OH) _2 ), carbon dioxide (CO _2 ) and ethylene diaminetetraacetic acid strontium salt ...
