Viral aerosol transmission of SARS-CoV-2 from simulated human emission in a concert hall

Autor: Wolfgang Schade, Vladislav Reimer, Martin Seipenbusch, Ulrike Willer, Eike G. Hübner

Publikováno v: International Journal of Infectious Diseases, Vol 107, Iss , Pp 12-14 (2021)

The dispersion of aerosols was studied experimentally in several concert halls to evaluate their airborne route and thus the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreading. For this, a dummy was used that emits simulat

Synthesis of γ-hydroxy-α-(arylmethyl)carboxylic acids from lactones: pathway to a structural motif derived from lactic acid and amino acid analogs?

Autor: Nicole Panzier, Fabian Uhrner, Felix Lederle, Jan C. Namyslo, Eike G. Hübner

Publikováno v: BMC Research Notes, Vol 12, Iss 1, Pp 1-6 (2019)

Abstract Objective A synthetic pathway to γ-hydroxy-α-(arylmethyl)carboxylic acids starting from α-angelica lactone and γ-butyrolactone was investigated. These γ-hydroxycarboxylic acids resemble structural motifs of lactic acid and amino acids.

Customizing the Appearance of Sparks with Binary Metal Alloys

Autor: Philipp Memmel, Felix Lederle, Martin Söftje, Jannis Koch, Mingji Li, Wolfgang Schade, Eike G. Hübner

Publikováno v: ACS Omega. 7:28408-28420

Long-flying sparks are an essential part of several pyrotechnic effects. Unfortunately, and in contrast to colored flames, the color space of sparks is basically limited to the black body curve. With low-boiling-point metals, vapor-phase combustion a

Sydnone Methides: Intermediates between Mesoionic Compounds and Mesoionic N‐Heterocyclic Olefins

Autor: Sebastian Mummel, Felix Lederle, Eike G. Hübner, Jan C. Namyslo, Martin Nieger, Andreas Schmidt

Publikováno v: European Journal of Organic Chemistry. 26

Sydnone methides represent an almost unknown class of mesoionic compounds which possess exocyclic carbon substituents instead of oxygen (sydnones) or nitrogen (sydnone imines) in the 5-position of a 1,2,3-oxadiazolium ring. Unsubstituted 4-positions

p-Block metal complexes with bis(pyrazol-1-yl)acetato ligands

Autor: Stephan Pflock, Frauke Langer, Michaela Reil, Lisa Strinitz, Rebecca Lorenz, Eike G. Hübner, Nicolai Burzlaff

Publikováno v: Dalton Transactions. 51:3902-3912

Sn(ii) and Ga(iii) complexes bearing bis(pyrazol-1-yl)acetato (bpza) or bis(3,5-dimethylpyrazol-1-yl)acetato (bdmpza) ligands are reported. The homoleptic complexes exhibit either mononuclear or dinuclear molecular structures.

Publikováno v: European Journal of Organic Chemistry. 2022

Dicationic bis-quinolinium salts possessing different types of conjugation are presented in which the hetareniums are separated by acetylenic or 1,4-diethynylbenzene spacers. Cross-conjugation is induced by interconnections via the 3-positions of the

Sydnonmethide – fast vergessene Mesoionen als Vorläufermoleküle von anionischen N‐heterocyclischen Carbenen

Autor: Eike G. Hübner, Andreas Schmidt, Felix Lederle, Martin Nieger, Sebastian Mummel, Jan C. Namyslo

Publikováno v: Angewandte Chemie. 133:19032-19037

Wir beschreiben Sydnonmethide, von denen bisher nur ein einziges Beispiel in der Literatur erwähnt worden war. Sydnonmethide können zu Anionen deprotoniert werden, die als π-elektronenreiche anionische N-heterocyclische Carbene formulierbar sind.
