Special Issue "X-ray Ptychography Technology: Recent Developments and Applications"

Dear Colleagues,

Ptychography for nanoscale imaging has attracted significant research effort over the last decade, hence it has come to the fore-front of high-resolution microscopy. Real-time imaging of structural, chemical, electronic and magnetic changes in materials that are useful for strained semiconductors, catalysts, memories and batteries, and so on, in industrial application, could enormously benefit from more developments, for example, (hyper-)spectral-ptychography to study the location and the speciation of the chemical elements. Additionally, mixed-states ptychography in conjunction with machine-learning (ML) computational algorithms can be incorporated into the existing ptychographic methodology to accelerate its fast development and realize the full power of the technique.

The aim of our Special Issue is to attract high-quality original paper on advances in ptychography in the x-ray and optical regime (new algorithms, operando applications, dichroism). Topics of interest include, but are not limited to, the following:

• Spectral-ptychography;
• Laminography, 4D ptychography-tomography;
• In situ nano batteries, catalysts and magnetism;
• Machine learning, deep learning;
• Near-field ptychography;
• Linear and circular dichroism ptychography.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Optics is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
