i‐Tac: Inverse Design of 3D‐Printed Tactile Elastomers with Tuneable Optical and Mechanical Properties

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
Inspired by the multi‐tissue architecture of the human fingertip dermis (A), this work introduces a mixture design using three PolyJet materials (AC/TM/GM) to expand the achievable elastomer property space (B). An inverse design pipeline (i‐Tac) is developed to map target optical/mechanical requirements to optimal material compositions (C), enabling ...

Ultrasonic Rainbow: A Meta‐Transducer for Frequency‐Selective Elastic Wave Control via Dithering‐Based Wavenumber Tuning

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces

Laser &Photonics Reviews, Volume 20, Issue 16, 21 August 2026.
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Integrated Design and Process Optimization of FDM‐Fabricated Hexagonal Architected Thin‐Walled PA12 Tubes for Improved Compressive and Energy Absorption Performance

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
FDM‐fabricated PA12 thin‐walled tubes with five hexagonal architected designs (D1–D5) of increasing nodal connectivity were investigated to determine the effects of wall architecture, layer height, and print angle orientation on compressive performance, energy absorption, and dimensional accuracy.

First‐Principle Analysis of the Structural, Elastic, Electronic, and Optical Properties of Novel AHgF3 (A = K and Fr) Perovskite

Nano Select, Volume 7, Issue 8, August 2026.
The evaluation of the physical properties of novel KHgF3 and FrHgF3 perovskites is explored. Both compounds are thermodynamically stable and mechanically ductile. Featuring narrow band gaps around 0.53–0.60 eV, these materials show strong potential for use in flexible infrared‐to‐visible optoelectronics and energy conversion devices.

The Viscoelastic Behaviour of Auxetic Metamaterials

physica status solidi (b), Volume 263, Issue 8, August 2026.
Stretch‐only auxetic unit‐cell viscoelastic models are extended from elastic honeycomb and keyway lattices using Maxwell and standard‐linear‐solid representations. Different horizontal and oblique relaxation responses make Poisson's ratio time‐ and frequency‐dependent, enabling tuneable auxetic behaviour for damping and adaptive structures.
