Nanostructured, mesoporous Au/TiO2 model catalysts – structure, stability and catalytic properties
Beilstein Journal of Nanotechnology, 2011 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

FEBS Open Bio, EarlyView.Cerebral organoids were employed as a novel model to explore the neurotoxicity of soman. Soman inhibited acetylcholinesterase activity, increased cell apoptosis and upregulated endoplasmic reticulum (ER) stress markers glucose‐regulated protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP).

Transmission Helium Ion Microscopy of Graphene [PDF]
arXiv, 2020 We compare transmission He ion microscopy (HIM) to transmission electron microscopy (TEM) of graphene support films. We present spot transmission patterns that compare with scattering and range of ions in materials (SRIM) predictions, and show examples of scanning He$^+$ transmission images, based on integrated camera intensity.

ELECTRON TRANSMISSION MICROSCOPY
Le Journal de Physique Colloques, 1974 The purpose of this short lecture is to explain why defects are imaged in the electron microscope, and to emphasize that a good understanding of the theory can lead to important informations about the defects. First, the different notions and parameters describing the diffraction of electrons by a perfect foil are introduced and discussed to some ...

Advanced glycation end products promote the release of endothelial cell‐derived mitocytosis
FEBS Open Bio, EarlyView.Under diabetic conditions, AGEs induce mitochondrial damage in HUVECs, activating migrasome‐mediated mitocytosis. Migrasomes encapsulate damaged mitochondria and are released into the extracellular space, facilitating intercellular mitochondrial transfer.

Oriented attachment explains cobalt ferrite nanoparticle growth in bioinspired syntheses
Beilstein Journal of Nanotechnology, 2014 Oriented attachment has created a great debate about the description of crystal growth throughout the last decade. This aggregation-based model has successfully described biomineralization processes as well as forms of inorganic crystal growth, which ...
