Profilometric Analysis of Worn Surface of Bronze, Iron and Iron Composite Samples, by Pin-on-Disk Method

open access: yesThe Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2013
In this study are presented the results of profilometric analysis for the wear of bronze materials, cast iron and composite materials. These materials were tested under dry wear conditions, using "pin-on-disk" method on a UMT-2 tribotester at a room ...

Broadband Silicon‐On‐Glass Reflective Dielectric Metasurface for THz Beam Steering in 6G Wireless Networks

open access: yesAdvanced Functional Materials, EarlyView.
A CMOS‐compatible, all‐dielectric Silicon‐on‐Glass reflective metasurface enables low–loss terahertz wavefront control for future 6G wireless communication. Mie‐resonant silicon pillars provide full phase coverage near 500 GHz, achieving experimentally validated single‐, dual‐, and five‐beam steering with sub‐1.5° angular error and less than 3 dB ...

Mono‐Material Polydisulfides for Pressure Sensitive Adhesive Tapes With Closed‐Loop Recyclability

open access: yesAdvanced Functional Materials, EarlyView.
A high‐performance pressure‐sensitive adhesive (PSA) tape is developed where both the adhesive layer and plastic backing layer can be recycled back to monomer in a closed‐loop cycle. Both layers of the tape are composed of analogous polydisulfide copolymers using only two unique monomers, thus giving it a mono‐material design and enabling recycling of ...

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures
