A plasma processing chamber and methods for operating the chamber are provided. An exemplary chamber includes an electrostatic chuck for receiving a substrate and a dielectric window connected to a top portion of the chamber. An inner side of dielectric window faces a plasma processing region that is above the electrostatic chuck and an outer side of the dielectric window is exterior to the plasma processing region. Inner and outer coils are disposed above the outer side of the dielectric window, and the inner and outer coils are connected to a first RF power source. A powered grid is disposed between the outer side of dielectric window and the inner and outer coils. The powered grid is connected to a second RF power source that is independent from the first RF power source.

Electrochemical processes and apparatus for obtaining metals from metal salts, including for separating alkali metal and alcohols from alkali metal alkoxide compounds, are disclosed. Aqueous solutions of metal alkoxides or metal carbonates are converted to metals by electrochemical processes which may also be integrated into processes for the production of borohydrides, such as sodium borohydride.

A method for identifying hair conditioner-resistant hair-binding peptides is described. The hair conditioner-resistant hair-binding peptides bind strongly to hair from a hair conditioner matrix and are stable therein. Peptide-based benefit agents, such as hair conditioners and hair colorants, based on the hair conditioner-resistant hair binding peptides are described. The peptide-based hair conditioners and hair colorants consist of a hair conditioner-resistant hair-binding peptide coupled to a hair conditioning agent or a coloring agent, either directly or through an optional spacer. Hair care and hair coloring product compositions comprising these peptide-based hair conditioners and colorants are also described.

Peptides have been identified that bind with high affinity to body surfaces, such as, hair, skin, nails, teeth, gums, and oral cavity surfaces. Diblock and triblock peptide-based body surface coloring reagents formed by coupling a body surface binding peptide to a pigment binding peptide, either directly or through a spacer, are described. The peptide-based body surface coloring reagents may be used in conjunction with pigments to color body surfaces.

Reactors with a dynamic compression elements that control the catalyst bed structure and hydrodynamic conditions inside the reactor in response to physical and structural changes in the catalyst bed, and methods of operating catalytic reactors are provided. The reactors are adjustable and/or can self-adjust in response to changes in the packing of the catalyst bed due, for example, to the attrition of the catalyst. The catalyst reactor designs improve operation of fixed bed reactors and enable the use of a variety of catalysts and supports, including materials that would not typically be considered for use in fixed bed reactors, such as those with limited durability or with moderate mechanical strength.

Peptides have been identified that bind with high affinity to body surfaces, such as, hair, skin, nails, teeth, gums, corneal tissue, and oral cavity surfaces. Peptide-based body surface reagents formed by coupling a body surface binding peptide to a benefit agent are described. The peptide-based body surface reagents include peptide-based hair conditioners, hair colorants, skin conditioners, skin colorants, nail colorants, and oral care reagents. The peptide-based hair conditioners and hair colorants are comprised of a hair-binding peptide coupled to a hair conditioning agent or a coloring agent, respectively. The peptide-based skin conditioners and skin colorants are comprised of a skin-binding peptide coupled to a skin conditioning agent or a colorant, respectively. The peptide-based nail colorants are comprised of a nail-binding peptide coupled to a coloring agent. The peptide-based oral care reagents are comprised of an oral cavity surface-binding peptide coupled to an oral care benefit agent. In all these compositions, the peptide may be directly coupled to the active agent or the coupling may be via a spacer. Personal care compositions containing these peptide-based body surface reagents are also described.
摘要:
The present invention relates to the use of triborohydride salts as hydrogen storage materials. The present invention also relates to a system of using triborohydride salts to generate hydrogen gas for use in a fuel cell or other hydrogen-consuming device. A novel method of preparing triborohydride salts is also disclosed, wherein gaseous diborane is reacted with a carbonate suspended in a non-aqueous solvent in a suitable vessel with agitation. The process is typically carried out utilizing sodium carbonate to form sodium triborohydride. Other triborohydride salts can then be formed by cationic exchange. Hydrogen generating fuels according to the present invention include aqueous or hydroalcoholic solutions or slurries of a triborohydride salt, which may additionally contain a borohydride salt to provide operation over a broader temperature range.
