Adaptability analysis of travelling wavefront protection in LCC‐UHVDC transmission lines

IET Generation, Transmission & Distribution, 2023
The existing relay protections for line‐commutated converter (LCC)‐ultra high voltage DC (UHVDC) transmission lines are insufficient in protection sensitivity and operation speed. The travelling wavefront fault distance information can be used to improve

Surface Energy‐Confined Multi‐Layer Inkjet Printing for Customizable Optical Microstructures

Advanced Materials, EarlyView.
A surface energy‐confined multi‐layer inkjet printing strategy is developed for customizable fabrication of 3D optical microstructures. By combining interfacial energy confinement with layer‐by‐layer processing, various 3D curved optical microstructures with tailorable morphology, material composition, and spatial configuration are precisely fabricated

Multiple Spatial Frequencies Pyramid WaveFront Sensing [PDF]

, 2017
A modification of the pyramid wavefront sensor is described. In this conceptually new class of devices, the perturbations are split at the level of the focal plane depending upon their spatial frequencies, and then measured separately.

Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation

Advanced Materials, EarlyView.
In this work, a universal metasurface multiplexing strategy is presented based on non‐injective transformation. By jointly optimizing two metasurfaces, multiplexed channels achieve independent wavefront control, overcoming crosstalk limits of single‐layer designs.

Remote‐Controllable Immune‐Priming Spot Formation Via Nanocomplexed Hydrogel‐Assisted Histotripsy: Immunoasis

Advanced Materials, EarlyView.
A novel immunotherapeutic strategy combines injectable, adjuvant‐loaded hydrogels with externally controlled histotripsy to create immune‐priming sites within tumors. This approach generates millimeter‐sized immune‐activated lesions with flexible, patient‐tailored treatment scheduling, enabling precise immune activation through tumor ablation‐mediated ...
