Partial Growth of Crack in Laser Scribing of Glass

Journal of the Japan Society for Precision Engineering, 2007
The scribing of glass by a CO2 laser is much more effective compared to the conventional mechanical technology in use because the strength of the cut glass is improved since microcracks and particles along the cut edge are lessened. However, the crack depth of laser scribing is limited because the inner compressive stress region under the cooling area ...

Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing

Advanced Materials Technologies, EarlyView.
Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.

Flux Analysis of the Supercapacitor Performance at Component Level

Advanced Materials Technologies, EarlyView.
The central objective of this study is to introduce new approach and metrics for analyzing the supercapacitor performance at the component level. The lack of standardized evaluation methodologies for analyzing the nonlinear behavior of real system is critical and hinders progress of supercapacitor.

Two‐Photon Polymerized Microvascular Environments for Multicellular Modeling of the Blood–Brain Tumor Barrier

Advanced Materials Technologies, EarlyView.
Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Engineered Interfacial Control for Suppression of Phase Instability: Operando Visualization from Device to Module Scale

Advanced Science, EarlyView.
Operando real‐time current density–voltage absorption spectroscopy visualizes spatial phase evolution in mixed‐halide perovskites from device to module scale. Phase instability preferentially initiates in regions with insufficient carrier extraction, revealing electrical boundary conditions as governing factors.
