Flexural Strengthening of RC Continuous T-Beams Using CFRP

Fibers, 2020
In this paper, experimental investigations for strengthening reinforced concrete (RC) continuous beams were performed. Eighteen T-beams were cast, twelve of which were inverted T-beams where the flange portion of the T-beam was subjected to positive ...

Multiscale Interfacial Engineering Enables Robust Reconstituted Wood

Advanced Science, EarlyView.
Conventional adhesives used in wood composites create heterogeneous interfaces that cause stress concentration under humid or aqueous conditions, thereby compromising long‐term stability. A synergistic strategy integrating interfacial reconstruction and water‐induced regeneration transforms heterogeneous interfaces into homogeneous ones with ...

A Multimodal Piezoelectric Vertical Sidewall Architecture for Scalable In‐Plane NEMS Resonators

Advanced Electronic Materials, EarlyView.
A vertical in‐plane piezoelectric resonator design shifts frequency tuning from film thickness to lithographic lateral definition, facilitating monolithic multiband integration. Initially validated via microscale length‐extensional resonators, this cavities‐first fabrication approach scales to the nanoscale for high‐frequency operation.

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

HeaTrace: A Parametric Design‐to‐Fabrication Workflow for Thermally Programmable Soft Robots

Advanced Intelligent Systems, EarlyView.
A programmable thermal actuation workflow enables soft robots to be designed and fabricated with embedded heaters that drive multiple responses. By combining performance‐driven heater design with multimaterial fabrication, the system supports thermally triggered shape change, stiffness tuning, and thermochromic visual response, as demonstrated through ...

Behaviour of small masonry assemblages reinforced with a steel cord reinforced joint repointing [PDF]

, 2016
Unreinforced masonry (URM) walls are one of the oldest and most common types of construction elements in the world. However they are susceptible to failure when exposed to overstresses, caused by out-of-plane and in-plane loads.
