Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Buckled membranes for microstructures [PDF]

, 1994
Based on energy variation methods we calculated the deflection of membranes under the combined load of an external pressure and an internal lateral stress. A lateral load gives rise to buckling once a critical load is exceeded.

Critical Conditions of Plate Buckling Generated by Welding.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1998
This paper deals with a critical condition of a buckling deformation caused by welding. The buckling of welded plate is affected by welding conditions, sizes of plate and material properties. The experiments for making clear the critical condition of buckling were done under changing welding conditions, such as sizes and welding processes.

From In‐Silico Optimized Microfabrication to Experimental Validation: Engineering a Tridimensional Epi‐Intraneural Interface

Advanced Functional Materials, EarlyView.
An epi‐intraneural interface is developed through in silico optimization and a novel tridimensional microfabrication pipeline. The device integrates penetrating and epineural contacts on a flexible substrate. Mechanical, electrochemical, and in vivo testing in rat and pig reveal robust implantation, low‐threshold activation, and site‐dependent ...

Failure Processes in Embedded Monolayer Graphene under Axial Compression [PDF]

, 2016
Exfoliated monolayer graphene flakes were embedded in a polymer matrix and loaded under axial compression. By monitoring the shifts of the 2D Raman phonons of rectangular flakes of various sizes under load, the critical strain to failure was determined ...

A critical review on buckling restrained braces

Journal of the Croatian Association of Civil Engineers
Currently, buckling restrained braces are gaining popularity in earthquake resistant designs. These braces facilitate stable hysteretic behaviour with a non-buckling steel core encased in a steel tube, which is filled with concrete or mortar. However, in the last few years, researchers have observed that there is no need for the filler material and ...

Dual‐Percolative Planar‐Heterojunction Photoactive System for High‐Performance Stretchable Organic Photovoltaics Enhancing Power Output under Strain

Advanced Functional Materials, EarlyView.
A dual‐percolative planar‐heterojunction photoactive architecture enables intrinsically stretchable organic photovoltaics that combine high photovoltaic efficiency with enhanced mechanical robustness. Abstract Intrinsically stretchable organic solar cells (IS‐OSCs) are promising candidates for wearable power sources due to their ability to deform in ...
