Storage weight losses

The y-axis in Fig. 4 is the delivered capacity of methane at 298 K the x-axis is the weight-loss after activation in steam or COj. Delivered capacity is the volume of methane at STP delivered at 0.1 MPa (1 atmosphere) per volume of adsorbent, after storage at, and de-pressurization from, 4 MPa it is a convenient... 

ENA was recently used for remote on-line corrosion monitoring of carbon steel electrodes in a test loop of a surge water tank at a gas storage field. An experimental design and system for remote ENA and collection of electrochemical impedance spectroscopy (EIS) data (Fig. 13) have been presented elsewhere. In the gas storage field, noise measurements were compared with electrode weight loss measurements. Noise resistance (R ) was defined as... 

An interesting phenomenon has been observed in people who have lost weight. Removal of body fat decreases the amount available for storage of fat-soluble chemicals. Blood concentrations of DDT have been observed temporarily to increase following weight loss. In light of the discussion above, such an observation is not unexpected. 

A number of observations help to understand the mechanism of hematite formation from ferrihydrite in aqueous systems i. e. under conditions essentially different from those for solid-state transformation by dry heating (see 14.2.6). Air-dry storage of ferrihydrite containing 100-150g H20/kg of water (found by weight loss) at room temperature for 20.4 years in closed vessels led to partial transformation to fairly well crystalline hematite with a little goethite (Schwertmann et al., 1999). In contrast, no hematite was formed from ferrihydrite if the content of adsorbed water was substantially reduced (Stanjek and Weidler, 1992 Weidler, 1997) as seen from the following examples ...

HMTD is very unstable in storage. Its weight loss is 79% in 300 days at 50°, 150 days at 70° and 5 to 20 days at 90°, for material stored dry. Even under water it showed considerable decomp in 4 months (Ref 16)...
