X-ray microtomography imaging of craniofacial hard tissues in selected reptile species with different types of dentition
(Oxford University Press, 2022-03-07)Background Reptiles exhibit a large heterogeneity in teeth morphology. The main variability comprises the different tooth shape, the type of tooth attachment to the underlying bone, or the ability to replace the teeth. ... -
Remarkably stable metal-organic frameworks on an inert substrate: M-TCNQ on graphene (M = Ni, Fe, Mn)
(Royal Society of Chemistry, 2022-07-07)Potential applications of 2D metal-organic frameworks (MOF) require the frameworks to be monophase and well-defined at the atomic scale, to be decoupled from the supporting substrate, and to remain stable at the application ... -
Photonic integrated circuits with bound states in the continuum: comment
(Optica Publishing Group, 2022-06-21)We point out that the electro-optic modulation of the bound state in the continuum in a low-index dielectric-loaded slab LiNbO3 waveguide reported by Yu et al., [Optica 6, 1342 (2019)] is treated incorrectly. According to ... -
Twisted Rainbow Light and Nature-Inspired Generation of Vector Vortex Beams
(Wiley-VCH GmbH, 2022-06-06)Twisted vector light beams (optical vortices) arise from a spiral modulation of the geometric (Pancharatnam-Berry) phase converting the light spin to the orbital angular momentum. The preferred geometric-phase elements ... -
Advanced Microscopical Non-Invasive Examination of the Supposed Migrastatics for Impact on In Vitro Cell Migration

Deviations of the SLM produced Lattice Structures and Their Influence on Mechanical properties
(MDPI, 2022-04-26)Selective laser melting (SLM) is an additive manufacturing technology suitable for producing cellular lattice structures using fine metal powder and a laser beam. However, the shape and dimensional deviations occur on the ... -
The Development of Dentin Microstructure Is Controlled by the Type of Adjacent Epithelium
(Wiley, 2022-02-01)Considerable amount of research has been focused on dentin mineralization, odontoblast differentiation, and their application in dental tissue engineering. However, very little is known about the differential role of ... -
Sample Holders for Sub-THz Electron Spin Resonance Spectroscopy
(IEEE, 2022-04-29)Electron spin resonance (ESR) is a powerful spectroscopic technique used to investigate samples with unpaired electrons in a broad range of scientific fields. High-frequency ESR (HF-ESR) spectrometers operating at sub-THz ... -
Resolving complex cartilage structures in developmental biology via deep learning-based automatic segmentation of X-ray computed microtomography images
(NATURE PORTFOLIO, 2022-05-24)The complex shape of embryonic cartilage represents a true challenge for phenotyping and basic understanding of skeletal development. X-ray computed microtomography (mu CT) enables inspecting relevant tissues in all three ... -
Memristors with Initial Low-Resistive State for Efficient Neuromorphic Systems
(Wiley, 2022-03-21)Memristive electronic synapses are attractive to construct artificial neural networks (ANNs) for neuromorphic computing systems, owing to their excellent electronic performance, high integration density, and low cost. ... -
Simultaneous assessment of energy, charge state and angular distribution for medium energy ions interacting with ultra-thin self-supporting targets: A time-of-flight approach
(Elsevier, 2021-03-01)We demonstrate simultaneous measurements of the charge state, energy and angular distribution of keV ions in transmission experiments through self-supporting foils. Using a time-of-flight approach we have introduced an ... -
