Coevolutionary Landscape Inference and the Context-Dependence of Mutations in Beta-Lactamase TEM-1 [PDF]

open access: yesbioRxiv, 2015
The quantitative characterization of mutational landscapes is a task of outstanding importance in evolutionary and medical biology: It is, e.g., of central importance for our understanding of the phenotypic effect of mutations related to disease and ...

Contrast by electron microscopy in thick biological specimens

open access: yesJournal of Microscopy, Volume 300, Issue 3, Page 341-355, December 2025.
Abstract The contributions of coherent bright‐field phase and incoherent dark‐field amplitude contrast are investigated for thick biological specimens. A model for a T4 phage is constructed and images simulated for both TEM and STEM phase contrast using a multislice code.

Plan-View Preparation of TEM Specimens from Thin Films Using Adhesive Tape [PDF]

open access: yes, 2011
A simple plan-view sample preparation technique for transmission electron microscopy (TEM) specimens is proposed for thin films by tearing-off the film with adhesive tape. The demand for very thin samples is highest for nanostructured materials where the

Chemically‐Disordered Transparent Conductive Perovskites With High Crystalline Fidelity

open access: yesAdvanced Science, Volume 12, Issue 42, November 13, 2025.
Kinetically arrested, chemically disordered perovskite thin films exhibit exquisite crystalline fidelity, broad IR–UV transparency, and low resistivity, despite incorporating five mismatched 3d–5d cations, including Cr and W. This study unites electronic correlation, cation diversity, valence complexity, and disorder—enabling new transparent conductors

Signaling pathway in breast cancer therapy [PDF]

open access: yesAvicenna Journal of Phytomedicine
Objective: This research attempted to increase the bioactivity and solubility and reduce the side effects of Tamoxifen (TMX) by using the cellulose nanocrystals (CNCs) extracted from walnut shells as a carrier and studied the interaction behavior of CNCs-

Defocus correction and noise reduction using a hybrid ptychography and Centre‐of‐Mass algorithm

open access: yesJournal of Microscopy, Volume 300, Issue 2, Page 167-179, November 2025.
Abstract Integrated Centre‐of‐Mass (iCOM) is a widely used phase‐contrast imaging method based on Centre‐of‐Mass (COM), which makes use of a 4D Scanning Transmission Electron Microscopy (STEM) dataset using an in‐focus probe. In this paper, we introduce a novel approach that combines Single‐Side Band (SSB) ptychography with COM and iCOM, termed Side ...
