Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

Advanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Alkali treatment influence on cellulosic fiber from Furcraea foetida leaves as potential reinforcement of polymeric composites

Journal of Materials Research and Technology, 2022
The present study explores the potential of the alkali-treated Furcraea foetida (FF) fibers as reinforcement materials in polymeric composites. The fibers were treated and soaked for 3 h in an alkali solution of different concentrations (3, 6, 9, 12, and

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Influence of lime, calcium silicate and portlandite on alkali activation of calcined common clays

Open Ceramics, 2021
The application of calcite rich common clays has marked impact on the formation of alkali-activated binders. Experiments have shown that the carbonate decomposition can be well controlled via the calcination procedure, whereby the majority of the ...

Single‐Step Recovery of Water from Stable Crude Oil‐Water Emulsion Using Surface Engineered Hybrid Inorganic‐Polymer Membranes

Advanced Functional Materials, EarlyView.
Atomic layer deposition is used to conformally surface engineer polymeric membranes to fabricate inorganic–organic hybrid membranes. These membranes have exceptionally strong attraction toward water even in high oil containing emulsions, which leads to an extremely strong hydration layer at the interface.

Visualizing alkali metal aggregation-induced coordination in CO2 activation on copper

Nature Communications
Alkali metals are widely recognized as promotors in CO2 activation and conversion. However, how the alkali metals activate CO2 molecules and stabilize the reaction intermediates remains controversial due to the lack of atomic-scale characterization. Here,

Polaron Model of Traps and their Activation Energies in KBr Crystals [PDF]

Журнал нано- та електронної фізики, 2017
The activation energy spectrum of traps in KBr crystals has been studied by the thermoluminescence (TL) methods in the temperature range of 80-450 Рљ. The energies of thermal activation of traps in KBr were found to form an oscillator-like series , with ...

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...
