摘要:
A hard coat composition comprising an acid functional organosiloxane polyol wherein at least some of the acid functionality has been neutralized is disclosed. The hard coat is suitable for application to a substrate, and can be used without an adhesive promoting primer.
摘要:
A method is provided for determining reference signal positions in a frequency-time domain in an Orthogonal Frequency Division Multiple Access (OFDMA) system. A plurality of sub-carriers are selected in one resource block according to a predetermined mother pattern for reference signal allocation. When a single resource block is assigned for transmission to a user, the reference signal positions are determined corresponding to the plurality of selected sub-carriers in the single resource block. When multiple resource blocks are assigned for transmission to a user, the reference signal positions are determined in the multiple resource blocks by reducing a number of the plurality of selected sub-carriers in the mother pattern for at least one of the multiple resource blocks.
摘要:
Liquid compositions are disclosed that include a photocatalytic material and a hydrophilic binder that includes an essentially completely hydrolyzed organosilicate. Also disclosed are methods of making such compositions, methods of coating a substrate with a hydrophilic composition, and substrates coated with such compositions. The compositions may, for example, be embodied as stable one-pack compositions.
摘要:
In a mobile communication system, a relay station (RS) is used for signal exchange with a base station (BS), and includes a first antenna set including at least one antenna, used for signal exchange with the BS, and a second antenna set including at least one antenna, used for signal exchange with a mobile station (MS). The RS selects at least one antenna from the second antenna set for each of the at least one MS, and exchanges a signal with the MS using the selected at least one antenna.
摘要:
Disclosed are replenisher compositions and methods of replenishing pretreatment compositions. The methods include adding a replenisher composition to a pretreatment composition wherein the replenisher composition includes: (a) a dissolved complex metal fluoride ion wherein the metal ion comprises a Group IIIA metal, Group IVA metal, Group IVB metal, or combinations thereof; (b) a component comprising an oxide, hydroxide, or carbonate of Group IIIA, Group IVA, Group IVB metals, or combinations thereof; and optionally (c) a dissolved metal ion comprising a Group IB metal, Group IIB metal, Group VIIB metal, Group VIII metal, Lanthanide Series metal, or combinations thereof.
摘要:
The present invention is directed to a coating composition comprising (i) a corrosion inhibitor and the (ii) reaction product of a calcium compound with an acid compound. The coating composition is deposited onto a substrate prior to the application of a pre-treatment coating composition (conversion coating) onto the substrate. The present invention is also directed to a substrate that comprises a coating system that comprises such a coating composition.
摘要:
A coating comprising the reaction product of a natural oil derived polyol, a lactide and a radiation curable moiety, such as a (meth)acrylate, are disclosed.
摘要:
A radiation diffractive material that diffracts radiation according to Bragg's law is disclosed. The material includes an ordered periodic array of diffracting regions received within a matrix, the matrix comprising an inorganic sol-gel.
摘要:
Multi-layer coatings are disclosed that include (1) a first layer comprising an inorganic oxide network, and (2) a second layer applied over at least a portion of the first layer, wherein the second layer is deposited from at least one liquid composition that is hydrophilic and includes an essentially completely hydrolyzed organosilicate. Also disclosed are substrates coated with such multi-layer coatings, methods of applying such multi-layer coatings to a substrate and methods for improving the anti-fouling, self-cleaning, easy-to-clean, and/or anti-fogging properties of an article.
