Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing

Advanced Functional Materials, EarlyView.
Maskless direct laser writing enables local control of oxygen stoichiometry in epitaxial YBCO thin films under ambient conditions. Sub‐micrometer grayscale patterns with tunable optical response and superconducting transport properties are achieved.

Development of Multifunctional Hierarchically Restructured Antibacterial Neural Interfacing Electrodes via Plasma‐Enhanced Atomic Layer Deposition of Zinc Oxide Thin Films

Advanced Functional Materials, EarlyView.
ABSTRACT Next‐generation implantable neural‐interfacing devices are increasingly constrained by the coupled demands of electrode miniaturization, electrochemical performance, and implantation infection risk. Femtosecond laser–based hierarchical surface restructuring (HSR) technology has emerged as a scalable, manufacturing‐compatible platform for ...

Dopant Distribution in Ga‐Implanted CdO—A Correlative Microscopy and Molecular Dynamics Study

Advanced Functional Materials, EarlyView.
This work demonstrates that ion implantation offset angle could modulate carrier concentration and mobility in cadmium oxide thin films. Combining correlative microscopy workflow and molecular dynamics simulations, this study reveals the control of interfacial cluster density with tailoring implantation angles, and the optimum offset angle that ...

Application of Glulam beam girders with external pre-stressing

, 2010
The paper presents details of a numerical analysis and construction of glulam beam girder structures with external pre-stressing. We have applied such structures on spans ranging from 24 to 32 m for the purpose of reduction of overall costs of glulam materials. For the external pre-stressing, steel braces S355 and Besista standard connectors were used.

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

An innovative steel-concrete joint for integral abutment bridges

Journal of Traffic and Transportation Engineering (English ed. Online), 2015
Integral abutment bridges are becoming rather common, due to the durability problems of bearings and expansion joints. At the same time, among short- and medium-span bridges, multi-beam steel-concrete composite deck with hot-rolled girder is an ...

Innovative pre-stressing and cambering of timber-to-timber composite beams

Composite Structures, 2019
Abstract The paper focuses on an innovative method to pre-stress and camber composite beams. The method relies on the compression force that can be generated by distributed screw fasteners inserted at an angle to the axes of the elements forming the composite structure (no external props or tendons are needed to pre-stress the structure).

Design and Characterization of a Two‐Dimensional Soft Array Based on Cooperative Dielectric Elastomer Actuators

Advanced Functional Materials, EarlyView.
A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.
