Orientation mapping of cp-Ti by reflected polarized light microscopy [PDF]

open access: yesMATEC Web of Conferences, 2020
Deformation and fracture mechanisms, and therefore mechanical behavior, in metals and metallic alloys with hexagonal close packed structures, such as α-Ti, strongly depend on the crystal c-axis orientation of the grains. Taking advantage of the intrinsic

A Quantum-Chemical Bonding Database for Solid-State Materials

open access: yesScientific Data, 2023
An in-depth insight into the chemistry and nature of the individual chemical bonds is essential for understanding materials. Bonding analysis is thus expected to provide important features for large-scale data analysis and machine learning of material ...

Assessing the reproducibility and up-scaling of the synthesis of Er,Yb-doped NaYF4-based upconverting nanoparticles and control of size, morphology, and optical properties

open access: yesScientific Reports, 2023
Lanthanide-based, spectrally shifting, and multi-color luminescent upconverting nanoparticles (UCNPs) have received much attention in the last decades because of their applicability as reporter for bioimaging, super-resolution microscopy, and sensing as ...

Crack growth and microstructural changes in AISI 52100: white etching cracks (WEC) and fine granular area (FGA) [PDF]

open access: yesMATEC Web of Conferences, 2019
The service life of rolling element bearings can usually be predicted with good accuracy. However, the damage phenomenon „white etching cracks” (WEC) can lead to premature and unforeseeable failures.

Dual color pH probes made from silica and polystyrene nanoparticles and their performance in cell studies

open access: yesScientific Reports, 2023
Ratiometric green–red fluorescent nanosensors for fluorometrically monitoring pH in the acidic range were designed from 80 nm-sized polystyrene (PS) and silica (SiO2) nanoparticles (NPs), red emissive reference dyes, and a green emissive naphthalimide pH

Investigating the uptake and fate of per- and polyfluoroalkylated substances (PFAS) in bean plants (Phaseolus vulgaris): comparison between target MS and sum parameter analysis via HR-CS-GFMAS

open access: yesEnvironmental Sciences Europe, 2023
In this study, we present a screening method based on molecular absorption spectrometry to study PFAS uptake and fate in plants. To evaluate the suitability of this method we analyzed plant extracts with molecular absorption spectrometry (MAS) as well as

Workflow towards automated segmentation of agglomerated, non-spherical particles from electron microscopy images using artificial neural networks

open access: yesScientific Reports, 2021
We present a workflow for obtaining fully trained artificial neural networks that can perform automatic particle segmentations of agglomerated, non-spherical nanoparticles from scanning electron microscopy images “from scratch”, without the need for ...
