TEM-based cathodoluminescence of a Selenium-alloyed CdTe solar cell

, 2021
Since 2015, commercial sample holders have been available that enable cathodoluminescence imaging of semiconductors in the TEM. Despite this, issues with low signal have meant that high resolution TEM-CL imaging has so far not been achieved on a solar ...

Distribution of Electrical Resistivity in Single Carbon Fiber Filaments and Its Correlation With Tensile Modulus

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
A statistical framework is applied to quantify the distribution of electrical resistivity among individual filaments of two commercially available carbon fiber types. Correlations between filament resistivity, tensile modulus, and diameter are examined and complemented by TEM analysis to provide new insight into filament‐level variability relevant for ...

Atomic‐Scale Insights Into Antisite‐Defect‐Induced Metallicity in Halide Perovskites

Small, Volume 22, Issue 14, 6 March 2026.
Using an aberration‐corrected scanning transmission electron microscope, we identify that the PbCs antisite defect in CsPbBr3 shortens the Pb─Pb bond by ∼20 pm, and induces local strain and polarization, leading to a semiconductor‐to‐metal transition.

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

A syntactic perspective on rhetorical purpose: The example of if-conditionals in medical editorials [PDF]

Ibérica, 2014
This paper provides an in-depth analysis of the functioning of if-conditionals in medical editorials (MEDs). As previous genre-based studies of medical discourse genres have shown, MEDs need to address at least three different types of readers and are ...

Structural characterization of newt tendon regeneration after complete transection: In vivo two‐photon imaging and transmission electron microscopy

Journal of Anatomy, Volume 248, Issue 3, Page 383-394, March 2026.
The present study characterized newt digital flexor tendon regeneration structurally at both micro‐ and nanoscales following complete transection and suggested that the mechanism of tissue regeneration differs between the early phase (until 6 weeks) and the late phase (after 6 weeks). Tendon stubs remained separated for up to 2 weeks after transection,

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

Reviews 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.

Loading Mode Dependence of Twin‐Twin Boundary Formation in a Textured Magnesium Alloy

Advanced Materials Interfaces, Volume 13, Issue 4, 17 February 2026.
The structures of twin‐twin boundaries formed by interactions between twin variants sharing the same or different zone axes in a deformed magnesium alloy are demonstrated. Lattice distortion around complicated interfaces promotes grain refinement in the subsequent thermomechanical process, enhancing the mechanical performance of magnesium alloys ...
