New experimental measurements on density, viscosity, and self-diffusion coefficient are presented for PEG200, PEG400, and several binary mixtures of tri- and hexaethylene glycol covering a temperature range from 298.15 to 358.15 K. Because PEGs are polydisperse, the exact compositions of PEG200 from six different vendors are analytically determined and found to be comparable. Thus, only two of the most differing PEG200 samples are further examined. The effects of water as the most common impurity on densities, viscosities, and self-diffusion coefficients are inspected as well as the results of the “dry” samples obtained by extrapolation to zero water content. The obtained results are carefully compared to the available literature data. The temperature dependence of these physical properties is investigated and found to be linear for density, while viscosity and self-diffusion coefficients follow the Arrhenius law. Attempts to calculate the properties of the binary mixtures and PEG200 samples from the mole fraction weighted average of the physical properties of the mixture components result in reasonable agreement. Agreement between calculated and measured molar volumes is within measurement uncertainty. Agreement of calculated and measured viscosities is mostly within a few percent but increases with decreasing temperature (largest viscosities) reaching values of up to 15%. Similarly, calculated and measured self-diffusion coefficients mostly agree within 20%, which is near the measurement uncertainty, but overestimates increase to 30% for the highest temperatures (largest self-diffusion coefficients)."}],"citation":{"mla":"Hoffmann, Markus M., et al. “Densities, Viscosities, and Self-Diffusion Coefficients of Several Polyethylene Glycols.” <i>Journal of Chemical and Engineering Data</i>, vol. 67, no. 1, American Chemical Society, 2022, pp. 88–103, doi:<a href=\"https://doi.org/10.1021/acs.jced.1c00759\">10.1021/acs.jced.1c00759</a>.","ama":"Hoffmann MM, Kealy JD, Gutmann T, Buntkowsky G.

A relative method for the comparison of the proportion of the direct and indirect polarization transfer pathways is established, allowing a direct comparison of the polarization efficacy for different radicals and different parts of the 1-octanol molecule despite differences in radical concentration or sample amount. With this approach, it could be demonstrated that the hydrophilicity is a key factor in the way polarization is transferred from the polarizing agent to the analyte. These findings are confirmed by the determination of buildup times Tb, illustrating that the choice of polarizing agent plays an essential role in ensuring an optimal polarization transfer and therefore the maximum amount of enhancement possible for DNP enhanced NMR measurements."}],"publication":"Solid State Nuclear Magnetic Resonance","citation":{"bibtex":"@article{Döller_Gutmann_Hoffmann_Buntkowsky_2022, title={A case study on the influence of hydrophilicity on the signal enhancement by dynamic nuclear polarization}, volume={122}, journal={Solid State Nuclear Magnetic Resonance}, author={Döller, Sonja C. and Gutmann, Torsten and Hoffmann, Markus and Buntkowsky, Gerd}, year={2022}, pages={101829} }","ama":"Döller SC, Gutmann T, Hoffmann M, Buntkowsky G.

If x, y ∈ M such that x is transient we have P_y (X_n = x) → 0 for n → ∞, and under mild aperiodicity conditions this convergence is monotone in that for some N we have ∀n ≥ N : P_y (X_n = x) ≥ Py (X_(n+1) = x). We use bounds on the rate of convergence of the Markov chain to its quasi-stationary distribution to obtain explicit bounds on N . We then apply this result to Bernoulli percolation with parameter p on the cylinder graph C_k × Z. Utilizing a Markov chain describing infection patterns layer per layer, we thus show the following uniform result on the monotonicity of connection probabilities: ∀k ≥ 3 ∀n ≥ 500k^62^k ∀p ∈ (0, 1) ∀m ∈ C_k :\r\nP_p((0, 0) ↔ (m, n)) ≥ P_p((0, 0) ↔ (m, n + 1)).

In contrast to conventional semiconductor lasers their temporal properties are not limited by the intensity dynamics, but are governed primarily by the interaction of the spin dynamics with the birefringent mode splitting that determines the polarization oscillation frequency. Another class of modern semiconductor lasers are high‐<jats:italic>β</jats:italic> emitters, which benefit from enhanced light–matter interaction due to strong mode confinement in low‐mode‐volume microcavities. In such structures, the emission properties can be tailored by the resonator geometry to realize for instance bimodal emission behavior in slightly elliptical micropillar cavities. This attractive feature is utilized to demonstrate and explore spin‐lasing effects in bimodal high‐<jats:italic>β</jats:italic> quantum dot micropillar lasers. The studied microlasers with a <jats:italic>β</jats:italic>‐factor of 4% show spin‐laser effects with experimental polarization oscillation frequencies up to 15 GHz and predicted frequencies up to about 100 GHz, which are controlled by the ellipticity of the resonator. These results reveal appealing prospects for very compact, ultrafast, and energy‐efficient spin‐lasers and can pave the way for future purely electrically injected spin‐lasers enabled by short injection path lengths.</jats:p>"}],"date_created":"2025-04-24T09:09:18Z","department":[{"_id":"977"}],"type":"journal_article","author":[{"first_name":"Niels","last_name":"Heermeier","full_name":"Heermeier, Niels"},{"last_name":"Heuser","first_name":"Tobias","full_name":"Heuser, Tobias"},{"last_name":"Große","first_name":"Jan","full_name":"Große, Jan"},{"full_name":"Jung, Natalie","first_name":"Natalie","last_name":"Jung"},{"full_name":"Kaganskiy, Arsenty","last_name":"Kaganskiy","first_name":"Arsenty"},{"full_name":"Lindemann, Markus","last_name":"Lindemann","first_name":"Markus"},{"full_name":"Gerhardt, Nils Christopher","first_name":"Nils Christopher","last_name":"Gerhardt","orcid":"0009-0002-5538-231X","id":"115298"},{"full_name":"Hofmann, Martin R.","first_name":"Martin R.","last_name":"Hofmann"},{"full_name":"Reitzenstein, Stephan","last_name":"Reitzenstein","first_name":"Stephan"}],"publication_identifier":{"issn":["1863-8880","1863-8899"]},"year":"2022","title":"Spin‐Lasing in Bimodal Quantum Dot Micropillar Cavities","intvolume":"        16","date_updated":"2026-02-19T14:23:16Z","publication_status":"published","language":[{"iso":"eng"}],"doi":"10.1002/lpor.202100585","citation":{"ama":"Heermeier N, Heuser T, Große J, et al.
