In situ synthesis, structural chemistry and vibrational spectroscopy of Zn-doped Ca5Mg4(VO4)6

open access: yesChimica Techno Acta, 2022
The phase formation of the solid solution Ca5Mg4–xZnx(VO4)6 (0≤x≤4) was studied in situ using differential scanning calorimetry and high-temperature X-Ray powder diffraction (XRPD). XRPD analysis shows the appearance of unavoidable secondary pyrovanadate

Evaluation of E-waste processing through secondary copper smelting

open access: yes, 2016
This presentation will report the processing of e-waste and extraction of the valuable metals through secondary copper smelting route (black copper smelting), as shown in Figure 1. The rationale for choosing the selected route will be explained.

High-Temperature Piezoelectric Sensing [PDF]

open access: yesSensors, 2013
Piezoelectric sensing is of increasing interest for high-temperature applications in aerospace, automotive, power plants and material processing due to its low cost, compact sensor size and simple signal conditioning, in comparison with other high-temperature sensing techniques. This paper presented an overview of high-temperature piezoelectric sensing

Low-Vacuum Pyrolysis of YBCO Films by Using Fluorine-Free Metal Organic Chemical Deposition

open access: yesCrystals, 2022
The preparation of YBCO superconducting films by using metal organic chemical deposition (MOD) involves low-temperature pyrolysis and high-temperature treatment. The former process generally requires the introduction of water vapor and other gases.

Thermal properties of fluoride mixtures near the melting point

open access: yesChimica Techno Acta
The thermal diffusivity of LiF-NaF-KF (FLiNaK), NaF-KF and FliNaK-NdF3 mixtures was studied by laser flash method near the melting point. The obtained results demonstrate that the thermal diffusivity of the melts slowly decreases within a certain ...

Recycled carbonates elevate the electrical conductivity of deeply subducting eclogite in the Earth’s interior

open access: yesCommunications Earth & Environment, 2023
The elevated pressure and temperature conditions encountered by a subducted slab entering the deep Earth can substantially alter the chemical composition and physical properties of recycled carbonates.

Stability and Thermoelasticity of Diaspore by Synchrotron X-ray Diffraction and Raman Spectroscopy

open access: yesFrontiers in Earth Science, 2021
The thermoelasticity and stability of diaspore (α-AlOOH, Al1.002Fe0.003OOH) were investigated in this study by in situ synchronous X-ray diffraction (XRD) and Raman spectroscopy methods at high pressure and high temperature conditions.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The opportunities to combine electronic functions at high temperature

open access: yes, 2022
In this talk a short introduction into CMOS on SIMOX technology will be given. As an example for the advantages of this technology the temperature behaviour of the CMOS devices and the basic digital cells will be shown.
