Transient changes of the optical response of WS2 monolayers are studied by femtosecond broadband pump–probe spectroscopy. Time-dependent absorption spectra are analyzed by tracking the line width broadening, bleaching, and energy shift of the main

Atomically thin layers of transition metal dichalcogenides are shown to exhibit a disappearance of strong excitonic absorption along with population inversion at the direct gap over a spectral range of hundreds of meV after pulsed photoexcitation.

German-Indonesian and German-Singaporean business co-operations face difficulties on both sides, which are linked to cultural differences. Based on field research carried out in the years 2000–2002, this article shows that the nature of the problem

Single- and few-layer crystals of exfoliated MoTe2 have been characterized spectroscopically by photoluminescence, Raman scattering, and optical absorption measurements. We find that MoTe2 in the monolayer limit displays strong photoluminescence. On

Single subunits of the A1 ATPase from the archaeon Methanosarcina mazei Go1 were produced in E. coli as MalE fusions and purified, and polyclonal antibodies were raised against the fusion proteins. A DNA fragment containing the genes ahaE, ahaC, ahaF

Chloroform/methanol was applied to cytoplasmic membranes of the thermophilic methanogens Methanothermobacter thermoautotrophicus and Methanothermobacter marburgensis as well as to the mesophile Methanosarcina mazei Go1. In any case, the chloroform/me

Recent molecular studies revealed nine to ten gene products involved in function/assembly of the methanoarchaeal ATPase and unravel a close relationship of the A1A0-ATPase and the V1V0-ATPase with respect to subunit composition and the structure of i

Three additional ATPase genes, clustered in the order ahaH , ahaI , and ahaK , were found upstream of the previously characterized genes ahaECFABDG coding for the archaeal A 1 A o ATPase from Methanosarcina mazei . ahaH , the first gene in the cluste
