In situ observation of ZnO nanowire growth on zinc film in environmental scanning electron microscope

, 2010
In situ uniform growth of ZnO nanowires was realized and monitored at real time by heating zinc film in an environmental scanning electron microscope. Better controllability and repeatability were obtained by using zinc film as source material compared ...

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

Advanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

The environmental scanning electron microscope (ESEM) - theory and applications

, 1993
The environmental scanning electron microscope (ESEM) allows direct observation of specimens in their natural state, without the need for elaborate sample preparation techniques. Recent technical developments allow the detection of various signals generated by the specimen, such as secondary and backscattered electrons, cathodoluminescence, and x-rays.

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

Advanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

Observation of wetting behavior of polypropylene microfibers by environmental scanning electron microscope

, 2002
The wetting behavior of polypropylene meltblown microfibers by water and oil was investigated using an environmental scanning electron microscope (ESEM). Water droplets were formed on the fiber surfaces by controlling temperature and pressure in the ESEM
