Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

An ab initio molecular dynamics investigation of the behaviour of amorphous substances in anodic aluminium oxide under electric field

Scientific Reports
In order to elucidate the diffusion behaviour of ions in alumina during the anodic alumina process, the effects of electric field strength, hydration content, and electrolyte on amorphous alumina and hydrated alumina were studied using ab initio ...

96% Alumina

, 2010
The image shows the classic angular shape of corundum (alumina) grains formed in a liquid medium. The intergranular regions are dark and contain the aluminosilicate glass left from the cooled liquid.

Alumina-embedded Au nanowires for SERS sensing

, 2011
We propose a novel substrate for SERS bio-sensing composed of an hexagonal array of gold nanorods embedded in an anodically-oxidized alumina substrate, reaching a surface field enhancement up to 220 ...

Interplay Between Phase Evolution, Fe Migration, and Oxygen Redox in O3‐Type NaxFeyMn1−yO2 Cathodes

Advanced Functional Materials, EarlyView.
Why do Na‐ion battery cathodes, that are compositionally closely related, follow different structural paths during battery operation? This work shows how Fe content controls when iron atoms migrate from their original sites. Early migration locks the layers and blocks key phase transitions, whereas delayed migration permits fuller structural ...

Alumina-graphite brick

, 2010
The fused alumina ceramic grain and natural graphite flakes (seen edge on in the micrograph) are held together by a polymer-derived carbon bond and protected from oxidation by a metal (bright Si) which betters oxygen in use to form e.g. SiO2.

Mineral phase transition of desilicated high alumina fly ash with alumina extraction in mixed alkali solution

, 2016
High alumina fly ash (HAFA), a main industrial solid waste produced in increasing amounts in western China, is a type of alumina-rich resource that can replace bauxite in the preparation of alumina.

Spectroscopic Investigation of Polysulfide Redox Evolution in Catholyte Solutions for Potassium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Potassium–sulfur batteries are investigated using UV–vis spectroscopy to track the evolution of potassium polysulfide species at elevated temperature. The study reveals sulfur radical anions as key intermediates and shows how solvent composition and cell design influence polysulfide stability, redox behavior, and cycling performance, providing insights

Impulse mechanical strength improvement of alumina by surface coating

Cailiao gongcheng
To increase the impulse mechanical strength of alumina, the pore structure of alumina was modified by surface coating. It was found that the impulse mechanical strength of alumina samples coated with aluminum chloride increases from 35 MPa to 51 MPa and ...
