The invention discloses a powdery attapulgite foaming agent. The technical scheme has the following key points: the powdery attapulgite foaming agent is composed of active attapulgite clay, sodium percarbonate, sodium pyrophosphate, lauryl sodium sulfate, sodium polyacrylate and poly-naphthalene formaldehyde sodium sulfonate. The finished product of the powdery attapulgite foaming agent is prepared by stirring, grinding and packaging the ingredients. The powdery attapulgite foaming agent has the advantages that the foaming agent is high in foaming capacity, more in bubbling times and large in unit volume foam production quality, and enables the outer films of foams to have good toughness so as to guarantee the foams not to be easily broken; the foams are good in stability, can exist for a long time without being defoamed, and are fine and smooth; holes generated in a medium are even in sizes; the water secretion quantity is low; and the used medium is good in compatibility, etc. The products produced by the powdery attapulgite foaming agent not only can effectively control the noise pollution, but also have the functions of heat preservation and air purification; and the powdery attapulgite foaming agent is suitable for producing light weight boards, light weight walls and noise reduction products.

A novel coordination complex formed by dinuclear metal complexation is provided. The complex is a dinuclear metal complex of a compound, wherein the compound comprises a conjugation ring system substituted with: a) an electron donating group selected from —OH, —SH and —NH2; b) an indicating group selected from a chromogenic group, a fluorescent group and an electrochemical group; and c) two binding auxiliary groups, in combination with the electron donating group each of which being coordinated with the metal to provide an anion bonding site, wherein as the complex binds to a anion, the coordination of the electron donating group with the metal is weakened and electron donation of the electron donating group to the conjugation ring system is reinforced such that the reinforced electron donation by the electron donating group is transferred through the conjugation ring system to the indicating group to produce an indicating signal concomitant with the change of its electronic density. The coordination complex shows high sensitivity and high selectivity for pyrophosphate over other anions in an aqueous solvent over a wide pH range. Therefore, the complex is useful for pyrophosphate assay as a pyrophosphate sensor.

The present invention is directed to a method of reducing intraocular pressure. The method comprises administering to a subject a pharmaceutical composition comprising an effective amount of a nucleoside 5′-pyrophosphate pyranoside or analogue, which is defined by general Formula I. The method of the present invention is useful in the treatment or prevention of ocular hypertension, such as found in glaucoma, including primary and secondary glaucoma. The method can be used alone to reduce intraocular pressure. The method can also be used in conjunction with another therapeutic agent or adjunctive therapy commonly used to treat glaucoma to enhance the therapeutic effect of reducing the intraocular pressure. The present invention also provides a novel composition comprising a nucleoside 5′-pyrophosphate pyranoside or analogues.

There is provided a white light illumination system including a radiation source, a first luminescent material having a peak emission wavelength of about 570 to about 620 nm, and a second luminescent material having a peak emission wavelength of about 480 to about 500 nm, which is different from the first luminescent material. The LED may be a UV LED and the luminescent materials may be a blend of two phosphors. The first phosphor may be an orange emitting Eu2+, Mn2+ doped strontium pyrophosphate, (Sr0.8Eu0.1Mn0.1)2P2O7. The second phosphor may be a blue-green emitting Eu2+ doped SAE, (Sr0.90-0.99 Eu0.01-0.1)4Al14O25. A human observer perceives the combination of the orange and the blue-green phosphor emissions as white light.
