In a similar study, Liebhafsky and Cairns (31) compared two arrangements of tubular, calcia-stabilized solid oxide fuel cells. In one arrangement, hydrogen and air were supplied to a single. 

Envirobond is a stabilization technology that may be applied in situ or ex situ to treat solids (soils, sediments, wastes, and sludge) contaminated with heavy metals and radionuclides. Envirobond s proprietary blend of chemical additives combine with heavy metals and radionuclides to form an insoluble, stable mass. The Envirobric volume reduction system compacts the stabilized solids into construction-grade bricks. 

The reliable long-term safety assessment of a nuclear waste repository requires the quantification of all processes that may affect the isolation of the nuclear waste from the biosphere. The colloid-mediated radionuclide migration is discussed as a possible pathway for radionuclide release. As soon as groundwater has access to the nuclear waste, a complicated interactive network of physical and chemical reactions is initiated, and may lead to (1) radionuclide mobilization (2) radionuclide retardation by surface sorption and co-precipitation reactions and (3) radionuclide immobilization by mineralization reactions, that is, the inclusion of radionuclides into thermodynamically or kinetically stabilized solid host matrices. 

Single-base casting powder the casting powder consists of nitrocellulose, stabilizer, solid additives for ballistic modification, and a small amount of plasticizer. The normal ratio of casting powder to casting solvent, 2 1 by volume, yields a final composition of approximately 60% nitrocellulose.

These examples show that the inherent difference which exists between the structure of the perfect crystal and that of its surface film is of chemical significance. A surface can trigger decompositions—e.g., in some azides—as well as stabilize solids—e.g., the decahydrate of sodium carbonate—which are not in equilibrium with the atmosphere. 

The radius of Ru atom is in the middle of that of Sn atom and Ti atom. The three elements can form stabilized solid solution during thermal oxidation and it can resist the formation of nonconductive Ti02. That is the reason why Sn02 electrode with interlayer processes longer service life. Ru02 coating has low oxygen evolution potential, which will result in low electrocatalytic...

The ability of many drugs to form salts affords the formulation scientist increased scope to optimize drug product performance. The formation of a drug salt can alter physicochemical properties such as physical and chemical stability, solid state characteristics such as crystal form, melting point, enthalpy, solvation, hygroscopicity, which in turn impact on processability, dissolution rate, and bioavailability, without...

Figure 35. Time evolution of the secondary dielectric relaxation loss spectrum of DPGDB on isothermal annealing at 173.15 K after rapid cooling from 300 K. From top to bottom, the data were obtained after the sample has been annealed isothermally at 173.15 K for times, ta, equal to 93 s, 745 s, 1353 s, 3752 s, and 7272 s elapsed after the thermal stabilization. Solid circles represent the spectrum obtained by slowly cooling the sample at 0.05 K/min. Vertical arrows show the frequencies of the maximum loss for the JG P- and the y-processes.

(b) Same as (a), with an additional S-layer recrystallized on top of the lipid bilayer, (c) Thiolated SCWPs directly bound to gold and interacting with an S-layer, with a lipid bilayer on top. (d) Same as (c).

MgO solid was used as adsorbent to simulate solid surface and micropore systems, because of its chemical inertness and stability. Solid surface system was constructed with the dimensions of a = 33.04A, b =16.62A and c = 42.HA, including 192 fluid molecules, 256 Mg atoms and 256 0 atoms in a unit cell. Solid surface and micropore (diameter = 4A) systems were constructed with the dimensions of a = 37.90A, b = 24.64A and c = 72.IOA, including 350 fluid molecules, 768 Mg atoms and 768 0 atoms in a unit...

A typical example of fluorlmetrlc determination on dry reagent films is that of serum Immunoglobulins reported by Wang et al. [48]. The method uses a stabilized solid-phase immunoadsorbent consisting of an antigen Immobilized on a cellulose nitrate-acetate disc stuck to a Stiq plastic sampler. The polymer disc acts both as a substrate for Immobilization and as an even surface on which highly precise fluorlmetric determinations can be conducted. The assay...
