Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing
Advanced Functional Materials, EarlyView.Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking
Advanced Functional Materials, EarlyView.This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Investigation into Lean-Burn Combustor Thermo-acoustic Instabilities: Modelling of Entropy Convection for Low Frequency Rumble Prediction [PDF]
New combustion methods, aimed to reduce emissions, are shown to be susceptible to instability. To reduce nitrogen oxides, the traditional diffusion flame is replaced by lean combustion, where fuel-air are partially premixed, and combustion conditions are

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.
