This diagram of the Luria-Delbrück experiment depicts colonies of phage-resistant variants ofE. coli(red) developing in petri dishes. (Qi Zheng,CC BY-SA) The next day, Luria transferred the bacteria in each tube into a dish filled with phages. The day after that, he counted the number ...
To get more insight into the crystalline quality of the samples, we performed X-Ray diffraction analysis (XRD). The diffractograms are presented in Fig. 2. A clear trend is observed: as the PAAH concentration increases, the intensity of the diffraction peaks associated with the ZnO wurtzite ...
(Fig.2). The upper floral surface of floating flowers had to remain dry to ensure apparent temperature measurements were taken on floral tissue, not a film of water on top of it. Alongside flowers, floating test tube racks were also placed in the water bath to prevent flowers from moving ...

The analysis was conducted on a double-flow-line-GC with a static HS-autosampler, detecting the analytes using a drift-tube IMS (DT-IMS) or a MS, as described in a previous work [61]. This allowed for the combination of the sensitive and powerful separation of the GCxIMS with the ...
(a) Schematic diagram of an HP-ETSC cross section, (b) components inside an HP-ETSC and (c) sizes and geometry of an evacuated-tube solar collector. A space between concentric glass tubes was vacuumed to reduce thermal energy loss from conduction and convection. The copper heat pipe was ...
