Combining the Pitcher and Lotus Plant: Supericephobic and Superhydrophobic Silicone Films

open access: yesAdvanced Science, EarlyView.
Based on bench‐top nanomolding of polydimethylsiloxane (PDMS) with optimized silicone oil content, we developed hierarchically structured silicone films by essentially combining the properties of the lotus and pitcher plant; particularly we are able to achieve water contact angle as high as 171° and ice adhesion strength as low as 11.5 kPa (i.e ...

Machine Learning Driven Window Blinds Inspired Porous Carbon‐Based Flake for Ultra‐Broadband Electromagnetic Wave Absorption

open access: yesAdvanced Science, EarlyView.
Inspired by the regulation mechanism of window blinds, this study designs an electromagnetic wave‐absorbing metamaterial. By introducing the magneto‐electric coupling concept and integrating it with an artificial intelligence‐based data‐driven collaborative optimization strategy, the material optimizes impedance matching performance and enhances loss ...

Blockchain: An Overview and Its Applications in Aviation

open access: yesHanggong uju uihakoeji, 2023
Blockchain is a type of distributed database managed through multiple network transaction details (P2P, Peer to Peer), and transaction information is stored on multiple computers (nodes) connected to the blockchain network instead of storing it in one

Absorption‐Dominant Electromagnetic Interference Shielding of Ti3C2Tx MXene‐Coated and Fe3O4‐Integrated TPMS Composites with Coupled Gradient Conductivity and Size‐Graded Structure

open access: yesAdvanced Science, EarlyView.
A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

A Janus‐Like Bio‐Inspired Strategy for 3D‐Printed Bimetallic Metamaterials with Excellent Thermal‐Protection and Load Bearing Capacity

open access: yesAdvanced Science, EarlyView.
A Janus‐like bio‐inspired strategy is proposed for integrally 3D‐printed bimetallic metamaterials. Inspired by shell bilayers, a heat‐resistant AlSiFeMnNiMg alloy and a SiC‐reinforced AlSi10Mg with different SiC volume fractions are arranged as an architected pair.

Work of Breathing for Aviators: A Missing Link in Human Performance

open access: yesLife
In this study, we explore the work of breathing (WoB) experienced by aviators during the Anti-G Straining Maneuver (AGSM) to improve pilot safety and performance. Traditional airflow models of WoB fail to adequately distinguish between breathing rate and

Scalable Laser Processing Enables Transparent, Accretion Scale‐Independent, Ice‐Shedding Glass

open access: yesAdvanced Science, EarlyView.
We demonstrate a scalable laser‐based method to create wave‐like micro‐patterns on glass surfaces that counter the conventional view that roughness increases ice adhesion. These patterns direct crack propagation at the ice–glass interface, enabling low‐force, multi‐directional ice detachment while maintaining substrate transparency. A theoretical model

Aerodynamic Design of a Tailless Aeroplan

open access: yesActa Polytechnica, 2001
The paper presents an aerodynamic analysis of a one-seat ultralight (UL) tailless aeroplane named L2k, with a very complicated layout. In the first part, an autostable airfoil with a low moment coefficient was chosen as a base for this problem.
