Cross sectional evaluation of boron doping and defect distribution in homoepitaxial diamond layers [PDF]
In some diamond-based semiconducting devices, large variations of doping level are required over short distances. Tools to determine doping level and defects distribution should therefore be developed.

Microscopy of glazed layers formed during high temperature sliding wear at 750C [PDF]
The evolution of microstructures in the glazed layer formed during high temperature sliding wear of Nimonic 80A against Stellite 6 at 750 ◦C using a speed of 0.314ms−1 under a load of 7N has been investigated using scanning electron microscopy (SEM ...

Scanning ultrafast electron microscopy [PDF]
Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200

Structural and gas-sensing properties of CuO–CuxFe3−xO4 nanostructured thin films [PDF]
Nanocrystalline CuO–CuxFe3−xO4 thin films were developed using a radio-frequency sputtering method followed by a thermal oxidation process. Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to ...

Nanostructured, mesoporous Au/TiO2 model catalysts – structure, stability and catalytic properties
Aiming at model systems with close-to-realistic transport properties, we have prepared and studied planar Au/TiO2 thin-film model catalysts consisting of a thin mesoporous TiO2 film of 200–400 nm thickness with Au nanoparticles, with a mean particle size

Transmission Electron Microscopy for Tobacco Chloroplast Ultrastructure
The chloroplast is the site of photosynthesis that enabled and sustains aerobic life on Earth. Chloroplasts are relatively large organelles with a diameter of ~5 μm and width of ~2.5 μm, and so can be readily analysed by electron microscopy.

Aβ42 promotes the aggregation of α‐synuclein splice isoforms via heterogeneous nucleation
The aggregation of amyloid‐β (Aβ) and α‐synuclein (αSyn) is associated with Alzheimer's and Parkinson's diseases. This study reveals that Aβ aggregates serve as potent nucleation sites for the aggregation of αSyn and its splice isoforms, shedding light on the intricate interplay between these two pathogenic proteins.
