Investigation of the heat affected zone by thermal cycle simulation technique

open access: yes, 2022
The heat generated during welding induces a large temperature gradient in and around the welded area. In the arc welding process, three main different zones have been recorded in the welded joint: the fusion zone, the heat-affected zone and the base metal.

Reconstructing Quantum Dot Surfaces via Dual‐Functional Ligand Pairing Enables Efficient Shortwave Infrared Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a ligand‐pairing strategy that reconstructs lead sulfide quantum dot surfaces for efficient short‐wave infrared optoelectronics. A low‐reactivity thiourea precursor combined with hydrobromic acid enables monodisperse and fully passivated quantum dots.

Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures

open access: yesAdvanced Functional Materials, EarlyView.
Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

open access: yesAdvanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

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 ...
