“…CNH elemental analysis was performed using a Perkin-Elmer 2400 II CNH analyzer. Mössbauer spectroscopy was performed at room temperature (19 • C) with a customized "WissEl" drive setup in transmission mode using a "MIMOS II" silicon pin detector [15,16]. Co-57 in a Rh matrix was used as the Mössbauer source.…”

Coordination compounds, like iron(II) triazole complexes, exhibit spin crossover (SCO) behavior at around room temperature. Therefore, they are interesting for a variety of possible applications, and it is convenient to integrate them into polymers. Due to a reduction of the iron content and thus also 57Fe content in the sample through integration in polymers, Mössbauer measurements are only possible with greater difficulty or very long measurement times without expensive enrichment of the samples with 57Fe. So, other ways of improving the Mössbauer signal for these composite materials are necessary. Therefore, we pressed these composite materials to improve the Mössbauer spectra. In this study, we synthesized an iron(II) triazole spin crossover complex and an electrospun polymer complex composite nanofiber material including the same complex. For both products, Mössbauer measurements were performed at room temperature before and after using a press to show that the complex composite is not harmed through pressing. We investigate the influence of the pressing impact on the Mössbauer measurements in the context of measurement statistics and the measured signals. We show that pressing is not connected to any changes in the sample regarding the spin and oxidation state. We present that pressing improves the statistics of the Mössbauer measurements significantly. Furthermore, we use SEM measurements and PXRD to investigate whether or not the obtained fiber mats are destroyed in the pressing process.

“…The sample spot was then sealed by another adhesive tape. The measurement setup consisted of a modified transmission Mössbauer spectrometer produced by Wissenschaftliche Elektronik GmbH Starnberg/Germany (WissEL) with a self-build drive control and data acquisition unit. , The γ radiation source comprised of 57 Co isotopes embedded in a Rhodium matrix, detected by a proportional counter detector. To measure the cooled Mössbauer spectra a self-build cryostat was used and operated with liquid nitrogen at 80 K. The data were fitted by a least-squares method using Lorentzian-shaped lines with the Recoil Mössbauer Analysis software.…”

For many applications of magnetic nanoparticles, the material must be dispersed in water. Therefore, this study used a two-phase system to transfer iron oxide (γ-Fe2O3 and Fe3O4) and iron platinum (FePt) nanoparticles to aqueous solution, using a low molecular weight catechol derivate (nitroDOPA). The monodisperse nanoparticles were synthesized in spherical and cubic shapes through high boiling point heat-up synthesis approaches followed by the phase transfer step. The colloidal nanoparticle solutions were investigated through infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and magnetometry measurements, giving a broad overview over the influence of the new catechol–ligand shell. It is shown that the nitroDOPA molecules bind through their catechol group on the surface of the magnetic nanoparticles, resulting in stable hydrophilic solutions under basic conditions. The physical properties of the magnetic nanoparticles were not altered by the ligand exchange reaction.

“…Considering that the basic requirement in the electronic applications of the industrial field is the applicability in different platforms, easy coding and the ability to connect cheap sensors, the first device that comes into mind is Arduino. Ardunio, which is an open-source microcontroller platform (Cezar et al, 2020) developed for the use of people from different fields, is a quite popular device that could perform simultaneous tasks with additional equipment (Jahns et al, 2019;Oussalem et al, 2020) enable the desired prototype to be created. Since Arduino has an Integrated Development Environment of its own (Vestenicky, Matuska, & Hudec, 2019), the codes that are generated in any computer could be transferred to the Arduino cards with the help of the USB connection.…”

In this study, the rainbow trout was stored under refrigeration conditions (3 ± 1 C) for 18 days. Changes in the resistance levels in head, meat and eyes, changes of color in the head and meat, changes of liquid levels in the skin and meat, and odor values in the head and the meat were measured with Arduino microcontroller card and recorded during the storing period. In order to perform a significant comparison with the data obtained via Ardunio, the total viable count, psychrotrophic count and Enterobacteriaceae count in the fish meat were identified on a daily basis during storage. The results of the study indicated that the resistance value on the meat decreased significantly as the storage period increased; and that the Arduino-based color, odor and liquid level measurement sensors could be used effectively in identifying the food quality.
