Facile Preparation of Carbon Membranes Derived from a Fluorenyl‐Containing Polyimine for Selective Hydrogen Separation

open access: yesAdvanced Functional Materials, EarlyView.
A fluorenyl‐containing polyimine is introduced as a simple, scalable precursor for high‐performance carbon membranes. The precursor's intrinsic kinked structure enables defect‐free membrane formation with enhanced hydrogen permeance and excellent ideal selectivities for key industrial gas pairs (H2/N2, H2/CH4, and H2/CO2), offering a practical route ...

A Holistic Stabilization of the Anode in Lithium‐Sulfur Batteries Through a Ternary Alloy Fusion

open access: yesAdvanced Functional Materials, EarlyView.
LiTeAl anodes fabricated through a scalable thermal fusion technique holistically addresses the stability issues faced by lithium‐metal anodes in lithium–sulfur batteries. Aluminum forming a skeletal network with lithium suppresses dendrite growth and enhances energy density, while tellurium forming a robust SEI facilitates Li+‐ion flow.

Application of Ibuprofen Sodium Dihydrate for Thermochemical Energy Storage

open access: yesAdvanced Functional Materials, EarlyView.
Ibuprofen sodium dihydrate is introduced as a durable organic salt hydrate for low‐temperature thermochemical energy storage, operating within 60°C–110°C with high energy density. At the material level, it delivers ∼99.9% cycling efficiency over 150 cycles without deliquescence, enabled by a dual energy‐storage mechanism coupling dehydration and phase ...

Alumina-zirconia-silica (AZS) refractory brick

open access: yes, 2010
On cooling the ceramic liquid precipitates primary ZrO2 dendrites (white), grey corundum (Al2O3) and a ZrO2/Al2O3 eutectic while glass solidifies from the remaining liquid (slightly darker than the corundum).

Effects of dispersion surfactants on the properties of ceramic – carbon nanotube (CNT) nanocomposites [PDF]

open access: yes, 2014
Gum Arabic (GA), Sodium Dodecyl Sulfate (SDS) and their mixture were used for the dispersion of multi-walled carbon nanotubes (CNTs) in an alumina matrix. A good dispersion at low loadings (0.5-1 wt%) of CNTs in alumina was achieved by an ultrasonic bath
