Acetylsalicylic Acid Promotes Corneal Epithelium Migration by Regulating Neutrophil Extracellular Traps in Alkali Burn

Frontiers in Immunology, 2020
Neutrophils are the first cells to migrate into the cornea in response to alkali burns, and excessive neutrophil infiltration is associated with inflammatory injury and a poorer prognosis.

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

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 ...

Active Corrosion Protection of Sintered AA7075 Aluminum Alloy via Mn Powder Addition

Advanced Engineering Materials, EarlyView.
AA7075 containing Mn‐rich particles is fabricated via spark plasma sintering using AA7075 and Mn powders. Corrosion resistance is evaluated through dip‐and‐dry tests using 0.1 M NaCl (pH 6.0), and mass loss decreases with increasing Mn addition. Mn‐rich particles function as a source of Mn ions, and formation of Mn‐accumulation films on Cu‐containing ...

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 ...

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

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,

Spatially Decoupling Heating and Evaporation for Convection‐Enhanced 3D Solar Evaporation With Continuous Salt Harvesting

Advanced Functional Materials, EarlyView.
An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...
