Nanostructure-enhanced infrared spectroscopy

Nanophotonics, 2021
While infrared spectroscopy is a powerful technique that provides molecular information such as chemical constituents and chemical structures of analytes, it suffers from low absorption cross-section resulting in low sensitivity and poor signal-to-noise ...

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

A New Type Microwave Absorption Materials: Metal–Organic‐Frameworks (MOFs) Used as Non‐Conductive Material Combination with P‐C‐800

Advanced Electronic Materials
Metal–Organic‐Frameworks (MOFs) are commonly used as microwave‐absorbing materials after pyrolysis treatment. Rare researchers treat MOFs as non‐conductive materials and use them as absorbing materials directly.

Bistable Networks Enable Complex Shape Changes. [PDF]

Adv Sci (Weinh)
Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Superconducting metamaterials [PDF]

Physics Reports, 2018
Metamaterials (MMs), i.e. artificial media designed to achieve properties not available in natural materials, have been the focus of intense research during the last two decades. Many properties have been discovered and multiple designs have been devised that lead to multiple conceptual and practical applications. Superconducting MMs have the advantage

Non-contact optical magnetic field sensor based on metamaterial nanomechanics

APL Photonics, 2022
We demonstrate a non-contact optical magnetic field sensor that is based on actuation of a metamaterial-microcavity by the magnetic Lorentz force. Magnetic field is transduced to a change of the sensor’s reflectivity.
