A photovoltaic element comprising: (a) a photovoltaic assembly; (b) a shingle portion connected to the photovoltaic assembly, the shingle portion including: (i) one or more flexible regions and (ii) one or more attachment regions; wherein the one or more attachment regions connect the photovoltaic element to a structure and the one or more flexible regions are flexed so that all or a portion of the attachment regions are located below the shingle portion; and wherein the one or more flexible regions, the one or more attachment regions, or both include one more drainage elements.

A porous discriminating layer is formed on a ceramic support having at least one porous wall by (a) establishing a flow of a gas stream containing agglomerates of particles and (b) calcining said deposited layer to form the discriminating layer. At least a portion of the particles are of a sinter-resistant material or a sinter-resistant material precursor. The particles have a size from 0.01 to 5 microns and the agglomerates have a size of from 10 to 200 microns. This method is an inexpensive and effective route to forming a discriminating layer onto the porous wall.

A porous ceramic composition having improved thermal stability is comprised of ceramic grains bonded together by grain boundary phase comprised of silica, yttrium and oxygen wherein the amount of alkali metals, alkaline earth metals and other transition metals not including rare earth metals is at most 2% by weight of the grain boundary phase.

Porous mullite bodies having improved thermal stability

A porous ceramic composition having improved thermal stability is comprised of ceramic grains bonded together by a grain boundary phase comprised of silica, rare earth element that is Eu, Gd, Nd or mixture thereof and oxygen and optionally yttrium, wherein the grain boundary phase has a amount of an alkali, an alkaline earth metal and a transition metal other than yttrium that is at most 2% by weight of the grain boundary phase.

Prepare an oriented polymer composition that is cavitated, has cross sectional dimensions all at least three millimeters and at least one de-oriented surface layer having a thickness of at least 80 microns and at least 50 microns less than half the thickness of the oriented polymer composition, the de-oriented surface layer having a lower degree of polymer orientation than a 100 micron thick portion of the oriented polymer composition adjacent to and below the de-oriented surface layer by sufficiently heat treating a surface of a cavitated oriented polymer composition.

A halogenated aromatic monomer-metal complex useful for preparing a polymer for electronic devices such as a light-emitting diode (LED) device is described. The aromatic monomer-metal complex is designed to include a linking group that disrupts conjugation, thereby advantageously reducing or preventing electron delocalization between the aromatic monomer fragment and the metal complex fragment. Disruption of conjugation is often desirable to preserve the phosphorescent emission properties of the metal complex in a polymer formed from the aromatic monomer-metal complex. The resultant conjugated electroluminescent polymer has precisely controlled metal complexation and electronic properties that are substantially or completely independent of those of the polymer backbone.

Aromatic monomer- and conjugated polymer-metal complexes

A conjugated or partially conjugated polymer including a structural unit of Formula (I); where T is an aryl or heteroaryl group that may be substituted or unsubstituted, or a C1-C24 alkyl group; R1 is alkyl, alkoxy, aryl group, cyano, or F; and a and b are independently selected from 1, 2 or 3. In addition, a composition of Formula (IV); wherein X is a halogen or a boronate group.

Aromatic monomer-and conjugated polymer-metal complexes

A halogenated bisdiarylaminopolycyclic aromatic compound, polymers made therefrom, and polymeric light emitting diode devices using the polymers are described. The halogenated compound is represented by formula (I), wherein Ar and Ar' are each independently substituted or unsubstituted aryl groups and Z is a polycyclic arylene group, wherein at least one of the Ar&#x2032; groups is a haloaryl group. Devices using polymers prepared from the halogenated compound exhibit improved performance and longer lifetime, presumably as a result of the presence of the geometrically constrained diarylaminopolycyclic aromatic groups in the polymer backbone.

The present invention relates to a composition comprising a blend of a luminescent polymer and a low molecular weight (&#x3c;5000 amu) viscosity modifier, which has an emission maximum in the range of 350-480 nm, contains no exocyclic double bonds, and modifies the viscosity of the polymer without substantially altering emissive properties of the neat polymer. Modification of viscosity without concomitant modification of emissive properties is desirable where the polymer is already tuned to emit at the desired wavelength.

Blend of viscosity modifier and luminescent compound

An organic block polymer useful in an electroluminescent polymer device (or in a polymer field effect transistor) that includes an emissive polymer block that is consistently conjugated along the backbone of the emissive polymer block (e.g., a copolymer of 2,7-linked 9,9 dioctyl fluorene and 4,7-linked 2,1,3 benxothiadiazole); and a positive charge carrier polymer block that is consistently conjugated along the backbone of the positive charge carrier polymer block (e.g., a copolymer of 2,7-linked 9,9 dioctyl fluorene and 4N, 4N&prime;-linked N,N&prime;-di(3-carboxomethoxyphenyl)benzidine) for transporting positive charge carriers to the emissive polymer block so that the positive charge carriers can combine with negative charge carriers to generate light.

Electroactive polymers and devices made therefrom

A polyamide precursor of a polybenzazole polymer is prepared by reacting an aromatic bis(alkenyl)ester with a ring forming, aromatic diamine. The precursor can be prepared in an organic solvent for the monomers to form a soluble polyamide precursor which can be subsequently cyclocondensed to form a PBX polymer. A polybenzoxazole precursor is prepared by the reaction of a bis(alkenyl)ester and a bis(ortho-hydroxyamine). A polybenzazole polymer is easily prepared by heating the polyamide, PBX precursor.
