Challenges and enablers in fluidization technology
AIChE Journal, EarlyView.Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Effect of aesthetic crown lengthening on life quality and self‐esteem: 2‐year study
Clinical Advances in Periodontics, EarlyView.Abstract Background A gummy smile can result from several factors, often leading to a disharmonious appearance and causing physical and psychological discomfort for the patient. This study aimed to evaluate changes in self‐esteem and quality of life for patients, as well as the recidivism rate, following aesthetic crown lengthening (ACL) surgery ...

Comparison of modelling approaches for liquid fluidized beds
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

Sparse-TFM Imaging of Lamb Waves for the Near-Distance Defects in Plate-Like Structures
Metals, 2019 The ultrasonic phased array total focusing method (TFM) has the advantages of high imaging resolution and high sensitivity to small defects. However, it has a long imaging time and cannot realize near-distance defect imaging, which limits its application
