High‐Gain Ag2Te/MoS2 Hybrid Photodetectors for Short‐Wave Infrared Imaging

Advanced Materials, EarlyView.
A precision‐engineered short‐wave infrared image sensor based on a 0D/2D Ag2Te/MoS2 hybrid structure is demonstrated in this work. The device exploits photodoping at the nanoscale interface to achieve broadband detection from visible to infrared wavelengths with high responsivity and fast response.

Design of a (mini) wide plate specimen for strain-based weld integrity assessment [PDF]

, 2011
Wide plate tension tests are commonly executed to investigate the integrity of defective welds under a uniaxial load. The specimen can be flat or curved, depending on the geometry from which it has been extracted (plate or pipe).

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Effect of Surface‐Lubricant Compatibility on Bubble Formation in Lubricant‐Infused Surfaces

Advanced Materials Interfaces, EarlyView.
Lubricant‐infused surfaces reduce drag partly through bubbles that form when lubricant depletes. Using laser‐textured steel infused with silicone oil, we show that microbubble nucleation occurs even on surfaces fully wetted by the lubricant, regardless of chemistry.

Advanced Mounting Technique for Improved Imaging and Analysis of Embedded Spheroids and Migrating Cells in Light Sheet Fluorescence Microscopy

Advanced Materials Technologies, EarlyView.
A novel sample holder compatible with the Zeiss Lightsheet 7 microscope improves imaging of spheroids embedded in collagen matrices. By enabling dual‐sided illumination, it enhances image quality and quantitative analysis of migrating cells. This method advances 3D light sheet microscopy for studying tumor invasion and therapeutic responses.

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

Advanced Materials Technologies, EarlyView.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.
