Potential trapping

Remove bracelets, rings, watches etc. to avoid potential traps of cryogen against skin. 

Casualties /personnel Remove all clothing as it may continue to emit "trapped" agent vapor after contact with the vapor cloud has ceased. Shower using copious amounts of soap and water. Ensure that the hair has been washed and rinsed to remove potentially trapped vapor. If there is a potential that the eyes have been exposed to nerve agents, irrigate with water or 0.9% saline solution for a minimum of 15 minutes. 

Direct Exposure In the event that an individual is at the scene of a known or suspected attack (e.g., white-powder letter, aerosol release, etc.), have them wash their hands and face thoroughly with antimicrobial soap and water as soon as possible. If antimicrobial soap is not available, use any available soap or shampoo. They should also blow their nose to remove any agent particles that may have been captured by nasal mucous. Remove all clothing and seal in a plastic bag. To avoid further exposure of the head, neck, and face to the agent, cut off potentially contaminated clothing that must be pulled over the head. Shower using copious amounts of antimicrobial soap (if available) and water. Ensure that the hair has been washed and rinsed to remove potentially trapped agent. The Centers for Disease Control and Prevention (CDC) does not recommend that individuals use bleach or other disinfectants on their skin.

The occurrence of such ion trapping is clearly undesirable since it inevitably leads to a decrease in conductivity. In practice, in materials that contain potential traps such as charged aliovalent impurities/dopants, the conductivity values of a particular sample may actually decrease with time as the mobile ions gradually become trapped. Such ageing effects greatly limit the usefulness of a solid electrolyte in any device that needs to have a long working-life.

Under dioxygen-deficient conditions, pyridinium cations can compete with dioxygen in capturing alkyl radicals (Scheme 3). The resulting alkylpyridinium radical cations rapidly rearomatize by means of Fe(III)-induced oxidation to afford alkylpyridines and replenish the pool of Fe(II) sites. Other potential traps of alkyl radicals are Fe(III)—Cl moieties, which are known to effect oxidative chlorination (Eq. 8). 

Electron transport in polymers or doped polymers occurs by charge transfer between adjacent acceptor functionalities. As for hole transport, the functionalities can be associated with a dopant molecule, pendant groups of a polymer, or the polymer main chain. Most literature references are of doped polymers. Compared to the veiy extensive literature on hole transport, there have been relatively few references to electron transport. In part, this is due to difficulties related to trapping. To accurately measure the mobility, materials are required in which trapping can be neglected. This requires acceptor molecules with electron affinities that are large compared to potential traps. Since O2, a potential electron trap, is invariably present at high concentrations, the electron... 

Hydrodynamic conditions influence the system of hydrocarbon migration in a basin, i.e. the volumes of hydrocarbons available for entrapment in a certain part of the basin, and the trapping energy conditions in the basin, i.e. the location of potential trapping positions and the sealing capacity of rocks and faults (Sections 5.2 and 5.3). 

At every point in a carrier-reservoir rock, uj,c, which is proportional to the hydrocarbon potential, cam be determined from the elevation z and the value of vj,c. which can be calculated from the groimdwater potential (Figure 8.7). The UVZ mapping procedure results in maps or cross-sections showing hydrocarbon equipotential surfaces in carrier-reservoir rocks from which hydrocarbon migration directions and potential trapping positions can be derived (Figures 8.8 and 8.9).
