How will you prepare 270 ml of a 20% sucrose solution (w/v), given that sucrose has a molecular formula of C_{12}H_{22}O_{11}? You have 1 liter of a freshly prepared 0.1 M sucrose (molecular mass 342) solution, which means ___. a) 6.02\...
HPLC analyses were performed under two different conditions, using a Zorbax Eclips XDB-C18 column (4:6 Â 150 mm) at a flow rate of 0.4 ml/min with UV detection at 340 nm. A mass range of m=z 100–1000 was covered, and data were collected in the negative ion mode (ESI). i)...
The mass spectrometer was operated in dynamic Multiple Reaction Monitoring (dMRM) mode with the detector set to negative ion mode. Analyte acquisition parameters are detailed in Table S3. Data analysis was performed using MassHunter Qualitative Analysis Navigator (Version B.08.00, Build 8.0.8208.0),...
The corrosion products can modify mass and charge transport to/from the surface, limiting corrosion rate. The inhibiting effect of several patinas, either synthetic or formed during field exposure, on the electrochemical reactivity of the Zn-based coatings has been demonstrated by many authors [1]...
Sample mass and relative humidity influenced the two qualitative variables, while particle size and biochar type only influenced the temperature. Keywords: biochars; moisture uptake; statistical modelling 1. Introduction Spontaneous combustion has long been recognized as a fire hazard in stored coal and ...
