Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

open access: yesAdvanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB

Transformation in Polish sea ports

open access: yesEkonomski vjesnik : Review of Contemporary Entrepreneurship, Business, and Economic Issues, 1999
Polish ports managed to pass apparently without any harm the period of economic transformation. Even at the earliest stage of economic recession, when flow of cargo from Polish exporters was cut down and simultaneously, dynamic development of private shipping business appeared as a new market power, the port activity was not seriously affected.

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

open access: yesAdvanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

Short and Length‐Independent Group Delay Supported by Topological Edge States in Finite‐Size Su–Schrieffer–Heeger Chains

open access: yesAdvanced Materials Technologies, EarlyView.
This study demonstrates short, length‐independent group delay supported by topological edge states in open Su–Schrieffer–Heeger networks. Strong boundary port coupling enables an order‐of‐magnitude latency reduction compared to bulk modes, alongside robust protection against bulk disorder.

Working with nature in wadden sea ports

open access: yes, 2017
Wadden Sea ports are situated at the border of the UNESCO World Heritage site Wadden Sea. Because of the protected status of this area, developing new economic activities is not straightforward. However, maintaining and developing port activities is needed to safeguard the economic viability of the Wadden Seasocio-economic region.

Understanding Inhomogeneous Crystallization Dynamics of Phase‐Change Materials in the Vicinity of Metallic Nanoantennas

open access: yesAdvanced Optical Materials, EarlyView.
Metallic dimer antennas on top of the phase‐change material Ge3Sb2Te6 are addressed with laser pulses, resulting in inhomogeneous crystallization. A self‐consistent multiphysics model is employed to simulate the crystallization and to understand the resulting shift of the antenna resonance.

Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without
