Development of Broadband Time-Resolved Spectroscopy and Investigation of the Dynamics of Photoexcited Carriers and Lattice Excitations in Chiral Weyl Semimetals
… repeated averaging over the spectrum. Using a bismuth test sample, we demonstrate that the apparatus is capable of measuring time-resolved changes in reflectivity ΔR of a sample over the 1.5 - 3.0 eV energy range with 25 fs temporal resolution, while also being sensitive to relative changes in …

Importance of bacterial hydrogen sulfide in the pathogenesis of periodontal diseases
… was investigated. Two colorimetric methods, the bismuth test (BT) and the methylene blue (MB) method, were used to estimate the amounts of H2S produced by the bacteria in vitro and ex vivo (Papers I, II and V). Oral bacteria, e.g., Fusobacterium spp., Porphyromonas gingivalis and Treponema …
