Article Synopsis
- Researchers adapted single-shot ptychography to the XUV range and tested it at the FLASH facility at DESY, achieving high-resolution imaging of a test sample.
- Traditional ptychography is slow due to its scanning process and struggles to capture dynamic events, while single-shot techniques collect multiple overlapping diffraction patterns in one go.
- The new setup combines X-ray focusing optics with a special beam-splitting diffraction grating, enabling rapid imaging of extended samples at X-ray wavelengths.
Polyethylene terephthalate (PET) is a thermoplastic polyester with numerous applications in industry. However, it requires surface modification on an industrial scale for printing and coating processes and plasma treatment is one of the most commonly used techniques to increase the hydrophilicity of the PET films. Systematic improvement of the surface modification by adaption of the plasma process can be aided by a comprehensive understanding of the surface morphology and chemistry.
