Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

open access: yesAdvanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐

Laser‐Induced Local De‐Doping in Organic Semiconductors

open access: yesAdvanced Materials Technologies, EarlyView.
The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

open access: yesAdvanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control

open access: yesAdvanced Materials Technologies, EarlyView.
A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Chitin‐Chitosan Cryogels for the Reversible Sequestration and Recovery of Heavy Metals From Wastewater

open access: yesAdvanced Materials Technologies, EarlyView.
Chitin‐chitosan cryogels with degrees of N‐acetylation from 12.2% to 71.4% are fabricated by dissolution, coagulation and lyophilization for the sequestration of heavy metals from water. Colorimetry and differential pulse voltammetry showed controlled adsorption and desorption capacities for As5+, Co2+ and Cu2+, making this material attractive for ...

Wind-Induced Vibration of Tubular Diagonals of the Werkspoorbridge

Structural Engineering International, 2004
Vibrations were recorded two months after the completion of the Werkspoorbridge in Utrecht, The Netherlands, during heavy winds. The vibrations were due to excitation generated by von Karman vortices. The vibrations could lead to fatigue damage. In situ measurements were conducted to determine the natural frequency and the damping ratio of the diagonal
