Abnormal grain growth (AGG), where a small number of grains grow to sizes much larger
than the neighboring matrix grains, is a frequent occurrence in liquid phase sintering of …

Several perovskite ceramics are known to have non-Arrhenius type grain growth and to
show grain growth transitions instead. These growth transitions are coupled to bimodal …

All-solid-state Li batteries (ASSLBs) are regarded as the systems of choice for future
electrochemical energy storage. Particularly, the garnet Li 7 La 3 Zr 2 O 12 (LLZO) is one of …

Abstract Ultrafast High-temperature Sintering (UHS) is a novel sintering process enabling
extremely high heating rates by direct contact of sample to electrically heated thin carbon …

The present study investigates the impact of point defects and their redistribution on the flash
sintering process. Strontium titanate was chosen as a model system for the group of …

A key issue in artificial photosynthesis is how to improve the separation and transport
efficiency of photogenerated carriers. The use of facet effect to promote the spatial charge …

High-energy x-ray diffraction microscopy (HEDM) nondestructively maps microstructures in
3D, allowing for the same grains and boundaries to be tracked over time during annealing …

Flash sintering involves very rapid densification of ceramic powder compacts during a
thermal runaway induced by an applied voltage and current. The mechanisms of fast …

The grain growth constant of strontium titanate shows a transition to slower grain growth in
the temperature range between 1300° C and 1390° C. The current study refines recently …

In functional ceramics, the impact of dopants on bulk crystals is generally well understood.
Their impact on grain boundaries is less well known. The present study investigates the …
