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 ...

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation

Nano-structural and nano-constraint behavior of mortar containing silica aggregates

open access: yesReviews on Advanced Materials Science, 2022
In this study, nano-structural and nano-constraints behavior of two silica aggregate mortars are investigated. The first silica aggregate (A) is almost pure silica and the second one (B) contains silica, calcite and dolomite phases.

EBIC/TEM investigations of process-induced defects in EFG silicon ribbon [PDF]

open access: yes, 1981
Electron bombardment induced conductivity and scanning transmission electron microscopy observations on unprocessed and processed edge-defined film-fed growth ribbon show that the phosphorus diffused junction depth is not uniform, and that a variety of ...

Structural transformation of layered double hydroxides: an in situ TEM analysis

open access: yesnpj 2D Materials and Applications, 2018
A comprehensive nanoscale understanding of layered double hydroxide (LDH) thermal evolution is critical for their current and future applications as catalysts, flame retardants and oxygen evolution performers.

Dislocation interaction with a tilt low‐angle grain boundary in bi‐crystal SrTiO3

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
A low‐angle tilt grain boundary (GB) was fabricated in SrTiO3 to study the dislocation and GB interaction at mesoscale. Dislocations were generated using Brinell indentation. Dislocation etch pit method and TEM observations both confirm dislocation pileup, storage, and transmission across the GB.

Sequential Adaptive Detection for In-Situ Transmission Electron Microscopy (TEM)

open access: yes, 2017
We develop new efficient online algorithms for detecting transient sparse signals in TEM video sequences, by adopting the recently developed framework for sequential detection jointly with online convex optimization [1].

Olivine Deformation: To B Slip or Not to B Slip, That Is the Question

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract When deformed by dislocation creep the dominant slip (Burgers) vectors of olivine dislocations are parallel to [100] or [001]. Dislocations with an [010] Burgers vector component (b dislocations) have been recorded rarely. Here we show an experimentally deformed olivine sample has a substantial population (17%) of b dislocations.
