Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth
Advanced Functional Materials, EarlyView.Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Tip Crack Imaging on Transparent Materials by Digital Holographic Microscopy
Journal of Imaging, 2019 With this study, we propose a method to image the tip crack on transparent materials by using digital holographic microscopy. More specifically, an optical system based on Mach−Zehnder interference along with an inverted microscopy (Olympus CKX53 ...

THE DECELERATION AND ACCELERATION OF CRACK PROPAGATION FOLLOWING TENSILE OVERLOAD AND HOLD TIME [PDF]
Journal of Engineering Science and Technology, 2018 The effect of the hold time of a tensile overload on crack propagation behaviours following the overload was investigated. In the study, the crack propagation behaviour after the overload was observed under constant amplitude load with stress ratio zero ...

Advanced Functional Materials, EarlyView.A transparent, laser‐microscribed glass platform enables cancer diagnosis within 1 h—much faster than histology, which takes days, and free from the chemical or contrast risks of MRI or CT scans. The antibody‐functionalized rough glass surface captures viable cancer cells directly from suspension, allowing instant optical readout and offering a rapid ...
