Molecular composition and volatility of multi-generation products formed from isoprene oxidation by nitrate radical

Publikováno v: Atmospheric Chemistry and Physics, Vol 21, Pp 10799-10824 (2021)

Isoprene oxidation by nitrate radical (NO3) is a potentially important source of secondary organic aerosol (SOA). It is suggested that the second or later-generation products are the more substantial contributors to SOA. However, there are few studie

Autor: S. R. Albrecht, A. Novelli, A. Hofzumahaus, S. Kang, Y. Baker, T. Mentel, A. Wahner, H. Fuchs

Publikováno v: Atmospheric Measurement Techniques, Vol 12, Pp 891-902 (2019)

Hydroxyl and hydroperoxy radicals are key species for the understanding of atmospheric oxidation processes. Their measurement is challenging due to their high reactivity; therefore, very sensitive detection methods are needed. Within this study, the

We report new photometric and spectroscopic observations of the K2-99 planetary system. Asteroseismic analysis of the short-cadence light curve from K2’s Campaign 17 allows us to refine the stellar properties. We find K2-99 to be significantly smal

Normal, superconducting and topological regimes of hybrid double quantum dots

Autor: Daniel Sherman, Jesper Nygård, Charles Marcus, S. M. Albrecht, Peter Krogstrup, Jeremy S. Yodh

Publikováno v: Nature Nanotechnology. 12:212-217

Epitaxial semiconductor-superconductor hybrid materials are an excellent basis for studying mesoscopic and topological superconductivity, as the semiconductor inherits a hard superconducting gap while retaining tunable carrier density. Here, we inves

Publikováno v: Nature. 531:206-209

Majorana zero modes are quasiparticle excitations in condensed matter systems that have been proposed as building blocks of fault-tolerant quantum computers [1]. They are expected to exhibit non-Abelian particle statistics, in contrast to the usual s

Publikováno v: PHYSICAL REVIEW APPLIED. 6:1-7

We report on fabrication of single-electron transistors using InAs nanowires with epitaxial aluminium with fixed tunnel barriers made of aluminium oxide. The devices exhibit a hard superconducting gap induced by the proximized aluminium cover shell a
