Suspendable and Scalable Ultrasound‐Actuated ZnO‐Nanosheet‐Based Piezoelectric Microdevices for Wireless Electrical Stimulation of Cells

open access: yesSmall, EarlyView.
Silicon microtechnology enables the scalable fabrication of cytocompatible microdevices for wireless electrical stimulation. Microdevices smaller than a cell allow accurate interaction with single cells. By integrating piezoelectric nanostructures that can be actuated by ultrasound within the biomedical range, remote electrical cell stimulation is ...

Supercapacitive Carbon‐Coated δ‐MnO2 Nanosheets as a Solid‐Contact Material for Self‐Testing Potassium‐Ion Biosensors

open access: yesSmall, EarlyView.
A simple and energy‐efficient method was developed to synthesize carbon‐coated δ‐MnO2 nanosheets (δ‐MnO2@C). This multifunctional material serves as both a supercapacitor electrode and a solid‐contact for self‐testing K+‐ion biosensors. Compared to activated carbon, δ‐MnO2@C enhances Faradaic supercapacitive properties, improving the K+‐ion sensing ...

Incremental upper bound modeling of concrete failures in timber‐concrete notched connections

open access: yesStructural Concrete, EarlyView.
Abstract This paper introduces a novel theoretical framework for developing incremental upper bound solutions, which is applied to predict the response of two local concrete failures in timber‐concrete composite (TCC) decks with notched connections. The new approach enables a prediction of the capacity at the onset of failure as well as the entire post‐

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders

open access: yesStructural Concrete, EarlyView.
Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.
