Enhanced surfaces, coatings, and related methods

Some embodiments provide a method of identifying a list of Femtocell Access Points (FAPs) for a user equipment (UE) communication session in a communication system including a first wireless communication system and a second wireless communication system. The second wireless communication system includes multiple FAPs and a Femtocell gateway (FGW) that communicatively couples the FAPs to the first wireless communication system. The method receives information about a UE that has detected a particular FAP that has an identification attribute. The method uses the UE information to retrieve a set of FAPs designated for the UE where the FAPs in the set of FAPs have the same identification attribute as the particular FAP. The retrieved set of FAPs is from a set of several FAPs that are not designated for the UE but have a same identification attribute as the particular FAP.

Method and apparatus to enable hand-in for femtocells

Active or functional additives are embedded into surfaces of host materials for use as components in a variety of electronic or optoelectronic devices, including solar devices, smart windows, displays, and so forth. Resulting surface-embedded device components provide improved performance, as well as cost benefits arising from their compositions and manufacturing processes.

Device components with surface-embedded additives and related manufacturing methods

Novel compositions of molecular sieve adsorbents are provided in which at least 50% of the exchangeable cations are selected from those of Li, Ca, Ag and Cu and which have within their pore system metal oxide, metal oxide precursors or mixtures thereof. These compositions are useful for the separation of gases and, in particular, the separation of nitrogen from air to produce oxygen or oxygen-enriched gas.

Adsorbents and adsorptive separation process

A sputtering target composed of indium oxide and zinc oxide. The content of zinc atoms ranges from 3 to 20 atom% based on the total of indium atoms and zinc atoms. The maximum particle diameter of the crystals in the sputtering target is 5 µm ore less. Few nodules are produced on the surface of the target while a transparent conductive film is formed by sputtering, and therefore the sputtering is conducted stably.

Sputtering target, transparent conductive film, and their manufacturing method

Disclosed in an indium oxide powder or indium oxide/tin oxide powder having a primary particle diameter of 1 to 0.01 µm, a surface area of 15 to 50 m²/g as measured by the BET method, and a specific surface area of 2 to 5 m²/g as determined from the particle diameter distribution. This powder is prepared by coprecipitating an indium- and tin-containing salt from a solution containing indium and tin, calcining the salt, and pulverizing the calcined product preferably using a specific vibrating pulverizer. A sintered body prepared by sintering the indium oxide/tin oxide powder has a density of at least 5.3 g/cm³, a specific resistance of 2 x 10⁻³ to 2 x 10⁻⁴ Ω-cm, and a sintered particle diameter of 5 to 15 µm.

A novel heat-resistant low-silica zeolite, an industrial production process, and uses of the low-silica zeolite are provided. The heat-resistant low-silica zeolite contains Si and Al in a molar ratio of SiO2 /Al2 O3 ranging from 1.9 to 2.1, and has sodium and/or potassium as metal cation, wherein the low-silica zeolite contains low-silica faujasite type zeolite at a content of not lower than 88%, and has a thermal decomposition temperature ranging from 870° C. to 900° C. in the air. The process for producing the heat-resistant low-silica zeolite comprises mixing a solution containing an aluminate with another solution containing a silicate, allowing the resulting mixture to gel, and aging the resulting gel, at the temperature of from 0° C. to 60° C., to prepare a slurry having a viscosity ranging from 10 to 10000 cp and containing amorphous aluminosilicate having a specific surface area of not less than 10 m2 /g with an SiO2 /Al2 O3 molar ratio ranging from 1.9 to 2.1; and subsequently crystallizing the aluminosilicate.
