Anatomical Distribution of Ultraviolet Radiation Depends on Phototherapy Unit Design and on Personal Height and Body Mass
Autor: Hans Christian Wulf, Peter A. Philipsen, Jakob Heydenreich
Publikováno v: International Journal of Translational Medicine, Vol 3, Iss 1, Pp 66-80 (2023)
Phototherapy using ultraviolet radiation (UVR) treatment units of various designs is common in dermatology. The anatomical distribution of UVR should be even, regardless of individual body shapes. Using electronic dosimeters, we measured the irradian

Autor: Philipp Weihs, Sarah Helletzgruber, Sofie Kranewitter, Lara Langer, Zacharias Lumerding, Viktoria Luschin, Philipp Schmidt, Jakob Heydenreich, Alois W. Schmalwieser
Publikováno v: Atmosphere, Vol 15, Iss 2, p 215 (2024)
Although cycling is the most prevalent means of locomotion in the world, little research has been done in evaluating the ultraviolet (UV) radiation exposure of cyclists. In this study, a volunteer using a men’s bike was equipped with 10 miniature U

The 1:1 reaction of benzamidinato-stabilized chlorosilylene PhC(NtBu)2SiCl (1) with CH(SiMe3)N2 resulted in the formation of colorless [PhC(NtBu)2Si(Cl){N2CH(SiMe3)}]2 (2), which consists of a four-membered Si2N2 ring. Surprisingly, N2 elimination fr

Autor: Jakob Hey, Eric Maedl, Manfred Scheer, Maria Eckhardt, Ricardo A. Mata, Dietmar Stalke, Sakya S. Sen, Herbert W. Roesky, Regine Herbst-Irmer
Publikováno v: Angewandte Chemie International Edition. 50:12510-12513
Don't count on counterions: The cyclic five-membered CSi(3)P cation 1 is synthesized in the reaction of benzamidinato-stabilized chlorosilylene and methyl phosphaalkyne. The presence of four π electrons in 1 means it can be considered as a formal, h

Regiospecific C–H Bond Activation: Reactivity Study of N-Heterocyclic Silylene toward Ambidentate Phosphorus Ylide
Autor: Jakob Hey, Sankaranarayana Pillai Sarish, Ramachandran Azhakar, Herbert W. Roesky, Dietmar Stalke
Publikováno v: Organometallics. 30:2897-2900
The reaction of two highly reactive species, the silylene [CH{C(Me)NAr}- {C(dCH2)NAr}Si] (L, Ar = 2,6-iPr2C6H3) and the phosphorus ylide MeC(O)CHPPh3, resulted in the formation of 1, involving regiospecific Calkyl H bond activation. Compound 1 was ch

Autor: Herbert W. Roesky, Sankaranarayana Pillai Sarish, Debasis Koley, Ramachandran Azhakar, Jakob Hey, Dietmar Stalke, Gašper Tavčar
Publikováno v: Inorganic Chemistry. 50:3028-3036
Three silicon centered spirocyclic compounds 1-3, possessing silicon fused six- and five-membered rings have been prepared by the reaction of NHSi (L) [L = CH{(C=CH(2))(CMe)(2,6-iPr(2)C(6)H(3)N)(2)}Si] with benzoylpyridine, diisopropyl azodicarboxyla
