  • Patent number: 8846853
    Abstract: A direct polycondensation method for medical biodegradable polylactic acid (PLA). The invention uses commercialized creatinine (a type of biomaterial organic guanidine compounds—the arginine metabolite creatinine in human body) as the catalyst and industrial lactic acid (mass content 85-90%, aqueous solution) as the monomer to synthesize the PLA in terms of second polycondensation without solvent. Instead of tin catalysts having cytotoxicity, the catalyst used in the invention has high biocompatibility and biosafety. The synthesized PLA does not contain any metal and other toxic components; therefore, it can be used as the carrier for targeting drugs and controlled release drugs. The green catalyst and green processing method (no solvent applied and no toxic products produced) are used to synthesize the green biodegradable PLA with high biosafety. The molecular weight distribution for all synthesized products is narrow and the molecular weight is controllable within 1.5-3.0×104.

  • Publication number: 20140256966
    Abstract: A method for stabilizing a metal or metal-containing particle supported on a surface is described, along with the resulting composition of matter. The method includes the steps of depositing upon the surface a protective thin film of a material of sufficient thickness to overcoat the metal or metal-containing particle and the surface, thereby yielding an armored surface; and then calcining the armored surface for a time and at a temperature sufficient to form channels in the protective thin film, wherein the channels so formed expose a portion of the metal- or metal-containing particle to the surrounding environment. Also described is a method of performing a heterogeneous catalytic reaction using the stabilized, supported catalyst.

  • Publication number: 20140256540
    Abstract: Photocatalytic materials are described herein which include thin nanostructures. For example, the catalytic material can include a nanostructure that has a thin structure of a photocatalytic composition, wherein the thin structure is defined by a first surface and a second surface on opposite sides of the thin structure of the photocatalytic composition. The photocatalytic composition may include an inorganic compound, such as a titanium and/or stannous oxide. The first surface and a second surface may be relatively large as compared to the thickness of the thin structure, or the thickness of the nanostructure.
