A Separated Reset Waveform Design for Suppressing Oil Backflow in Active Matrix Electrowetting Displays

open access: yesMicromachines, 2021
The electrowetting display (EWD) is a kind of reflective paper-like display. Flicker and grayscale distortion are caused by oil backflow, which is one of the important factors restricting the wide application of EWDs.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Model and characterization for dynamic non-uniform pixel capacitance in electrowetting displays

open access: yesResults in Physics, 2023
Electrowetting display (EWD) is a new reflective display device that has the advantages of fast response speed, low power consumption, and video playback. The pixel capacitance of EWDs changes with the flow of internal liquid during the pixel-on process,

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
