Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

X‐Ray Tomography Analysis of Damage Mechanisms in Metal Matrix Syntactic Foams During Compression

Advanced Engineering Materials, EarlyView.
In situ synchrotron X‐ray tomography is used to investigate the internal damage mechanisms of AlSi12 metal matrix syntactic foam with ceramic hollow spheres during compressive loading. It is concluded that a homogeneous distribution of the second‐phase filler material results in a sequential collapse in a localized region; this leads to controlled and ...

In situ n-doped nanocrystalline electron-injection-layer for general-lighting quantum-dot LEDs

Nature Communications
Quantum-dot optoelectronics, pivotal for lighting, lasing and photovoltaics, rely on nanocrystalline oxide electron-injection layer. Here, we discover that the prevalent surface magnesium-modified zinc oxide electron-injection layer possesses poor n-type

Negatively charged nanoporous membrane for a dendrite-free alkaline zinc-based flow battery with long cycle life

Nature Communications, 2018
Dendrite accumulation is a hindrance for alkaline zinc-based flow batteries. Here the authors design a negatively charged nanoporous membrane that mitigates zinc dendrite growth by repulsion of zincate anions, leading to a zinc-based flow battery with ...

One-step atmospheric microplasma synthesis of an NMC-type lithium-ion battery cathode

Electrochemistry Communications
The manufacture of battery cathode materials is the most energy-intensive step in the production of commercial lithium-ion batteries; specifically, the synthesis of the widely used transition metal oxide cathodes can require tens of hours at temperatures

Challenges during Flash Lamp Annealing of Aerosol‐Deposited Barium Titanate Films

Advanced Engineering Materials, EarlyView.
Aerosol deposition is used to rapidly deposit barium titanate films with thicknesses ranging from 2 to 16 μm at room temperature, eliminating the need for further densification. However, to recover the electromechanical properties, annealing is required, which limits the usage of temperature‐sensitive substrates.

Ionomer distribution control via thiophene S-modification of carbon support for high-power proton exchange membrane fuel cells

Nature Communications
Achieving a significant reduction in the cost of proton exchange membrane fuel cells (PEMFCs) is an imminent goal, and decreasing the overall platinum loading in the membrane electrode assembly (MEA) is regarded as a critical means to achieve this ...
