METHOD FOR PLANE NEAR-FIELD ACOUSTIC HOLOGRAPHY BASED ON COMPRESSIVE SAMPLING AND ITS APPLICATION

open access: yesJixie qiangdu, 2016
In traditional plane near-field acoustic holography reconstruction process,regardless of wave number domain filter or regularization method,they cannot solve their own ill-posed problem,and thus cannot improve the reconstruction accuracy.

Detecting charge transfer at defects in 2D materials with electron ptychography

open access: yesJournal of Microscopy, Volume 300, Issue 2, Page 156-166, November 2025.
Abstract Electronic charge transfer at the atomic scale can reveal fundamental information about chemical bonding, but is far more challenging to directly image than the atomic structure. The charge density is dominated by the atomic nuclei, with bonding causing only a small perturbation. Thus detecting any change due to bonding requires a higher level

Ptychographic analysis of human bone marrow‐derived mesenchymal stem cell morphology: The impact of cell senescence

open access: yesJournal of Microscopy, Volume 300, Issue 2, Page 227-233, November 2025.
Abstract Mesenchymal stem cells (MSC) undergo replicative senescence, a state of irreversible cell cycle arrest that limits their utility in regenerative medicine applications. To identify novel markers of senescence useful to enhance the quality of MSC‐based therapies, we compared young and senescent human bone marrow‐derived mesenchymal stem cells ...
