Multinuclear MAS NMR Identification of Fluorine Species on the Surface of Fluorinated γ-Alumina

, 2016
The fluorination on the γ-alumina surface was studied by multinuclear MAS NMR and BET measurements. The fluorine species on the fluorinated γ-alumina can be identified by 19F MAS NMR combined with 1H MAS NMR and 27Al MAS and CP/MAS NMR.

Measuring the Hall Effect in Hysteretic Materials

Advanced Materials, EarlyView.
The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Study of extracting alumina from high-alumina PC fly ash by a hydro-chemical process

, 2016
Alumina extraction from high-alumina pulverized coal (PC) fly ash by a mild hydro-chemical process characterized by a high alkaline sodium aluminate solution was studied. A high alumina extraction efficiency of 96.03% has been achieved.

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Properties and Preparation of Alumina Nanomaterials and Their Application in Catalysis

Micro
Nanomaterials are materials in which at least one dimension in three-dimensional space is at the nanoscale. In recent years, nano-alumina has attracted much attention due to its large specific surface area and pore volume, as well as novel optical ...

In Situ Regenerative Adduct Assisted p‐Type Doping of Organic Semiconductor

Advanced Materials, EarlyView.
An in situ regenerative adduct‐assisted (IRAA) doping strategy is introduced for p‐type doping of organic semiconductors. A regenerating adduct serves as the dopant, enabling highly efficient doping with a choice of counterions. The generality of this approach provides a scalable route to dope a wide range of hole‐transport materials with high thermal ...

Methanol‐Ethanol Discrimination and Selective Sensing Enabled by Molecular Sieving in Conductive MOFs

Advanced Materials, EarlyView.
Selective methanol sensors are achieved by coating carbon nanotube chemiresistors with two dimensional conductive metal–organic frameworks that incorporate intra‐pore clusters. These confined clusters increase the density of adsorption sites while restricting the transport of larger interfering molecules, particularly ethanol. This sensing architecture

Metal matrix composite of magnesium and alumina fibres

, 2010
The presence of the alumina fibres acts to inhibit the thermal expansion of the magnesium at temperatures up to 300°C. This is necessary in design situations where tolerances are critical.
