3D Propulsions of Rod‐Shaped Micropropellers

Advanced Intelligent Systems, Volume 3, Issue 11, November 2021., 2021
An asymmetric structural design is proposed to construct rod‐shaped micropropellers that can realize surface‐free 3D propulsions. These 3D micropropellers have an in‐plane rotating “spinning” mode to gain high speed and an out‐of‐plane biconical rotating “precession” mode to pass through narrow channels with a smaller rotation radius, which makes them ...

Assessing the Influence of Temperature‐Memory Creation on the Degradation of Copolyesterurethanes in Ultrathin Films

Advanced Materials Interfaces, Volume 8, Issue 6, March 23, 2021., 2021
Ultrathin films at the air water interface are manipulated in a controlled way to represent the semicrystalline morphology of a temperature‐memory polymer at distinct points of the programming/switching cycle. The degradability under enzymatic catalysis depends on the deformation temperature, which is also reflected in the viscoelastic properties ...

Experiment on Direction of Arrival Estimation of Atmospheric Spark Discharge Plasma Using Combined Time‐Domain Antenna

International Journal of Antennas and Propagation, Volume 2020, Issue 1, 2020., 2020
Apart from interfering in the communication system of an aircraft, electromagnetic pulses (EMPs) radiated from spark discharge plasma, which is generated during high‐speed flight, can also be utilized in passive detection. In order to validate this idea, an experiment on direction of arrival (DOA) estimation of a spark discharge plasma target using its

Post‐Shaping Over‐Impregnation: A Facile Strategy for Pt‐KL Catalysts With Ultrahigh Metal Dispersion and Enhanced Aromatization Performance

Carbon and Hydrogen, Volume 28, Issue 2, Page 196-208, June 2026.
A scalable post‐shaping strategy achieves precise Pt localization within KL zeolite, where optimized spatial distribution minimizes diffusion barriers to deliver superior n‐hexane aromatization activity, selectivity, and stability. ABSTRACT The precise localization of metal clusters within zeolite frameworks is critical for the aromatization catalysis.

Deep learning method for predicting electromagnetic emission spectrum of aerospace equipment

IET Science, Measurement &Technology, Volume 18, Issue 4, Page 193-201, June 2024.
Aiming at the typical and unpredictable spike signals in the electromagnetic compatibility test spectrum, a data decomposition method is adopted to extract such signals on the basis of a certain threshold and reconstruct them into a data sequence. After data decomposition, two data sequences are formed, and a long short‐term memory network is used for ...

Compact Archimedean spiral antenna with high gain for electrostatic discharge detection

IET Microwaves, Antennas &Propagation, Volume 18, Issue 3, Page 147-154, March 2024.
A compact Archimedean spiral antenna with high gain for electrostatic discharge (ESD) detection is investigated. A frustum‐shaped cavity (FSC) proposed in this work is formed to optimise the maximum antenna gain. The verified results indicate that the proposed antenna with compact size is preferred to be utilised for ESD detection.
