Two‐Photon Grayscale Lithography (2GL) of High Mechanical and Optical Quality 3D Silica Glass Microstructures

open access: yesAdvanced Functional Materials, EarlyView.
Two‐photon grayscale lithography (2GL) enables high‐speed and precise 3D printing of thermolyzed silica glass microstructures with optical‐grade surface quality, high quality factors, and mechanical strength utilizing a custom‐made pre‐glass resist based on polyhedral oligomeric silsesquioxane (POSS) modified with a high‐sensitivity Norrish type II ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

open access: yesAdvanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

Surface Integrated Printed Interdigital Structure for Process Monitoring the Curing of an Adhesive Joint

open access: yesProceedings, 2017
We present a printable interdigital structure, integrated into the surface of a component, to monitor the curing of two adhesively joint components during the fabrication process. In the factory of the future there is a need of new sensor concepts beside

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

open access: yesAdvanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Meniscus‐Guided Soft‐Lithographic Assembly of Grid‐Type Molecular Martensite Films for Single‐Crystal‐Like Actuation

open access: yesAdvanced Functional Materials, EarlyView.
A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).
