  • Patent number: 8614285
    Abstract: Disclosed is a novel photosensitizer based on polymer derivatives-photosensitizer conjugates for photodynamic therapy capable of being selectively accumulated in cancerous tissues and producing singlet oxygen or free radical by laser irradiation. The polymer derivatives-photosensitizer conjugates for photodynamic therapy are prepared as nano-sized particles, and have excellent selection and accumulation ratio for cancerous tissues. The photosensitizer conjugates can produce singlet oxygen or free radical by a specific laser wavelength. Owing to the excellent selection and accumulation ratio for cancerous tissues, the conjugates minimizes photo-cytotoxicity of the conventional photosensitizer having a low molecular amount. Accordingly, the conjugates are very useful as a photosensitizes for photodynamic therapy with reduced side effects and excellent therapeutic effectiveness.

Use of the treated filler during papermaking improves filler retention and produces filled papers where addition of the filler has only a minimal negative effect on strength properties. The swollen starch compositions can be prepared in a batch or jet cooker, or by mixing with hot water under controlled conditions (i.e., temperature, pH, mixing, mixing time) in order to make the starch granules swell sufficiently to improve their properties as a filler additive but avoiding excess swelling leading to their rupture. The swollen starch composition is then rapidly mixed with the filler slurry, preferably in a static mixer, and added to the papermaking furnish at a point prior to the headbox of the paper machine.

  • Publication number: 20110137004
    Abstract: A method of grafting galactomannan-type polysaccharide polymers, preferably guar, to a functional group by irradiation with high energy electron beams in the presence of an unsaturated monomer-compressing the described functional group. The method may include the depolymerization of the grafted polymer to a pre-selected low molecular weight. The preferred galactomannans for treatment according to this method are guar gum, guar splits and hydroxypropyl guar. In a preferred embodiment the guar gum is also depolymerized, preferably to a molecular weight of below about 700,00 Daltons, and most preferably to a molecular weight of between about 100,00 Daltons to about 250,00 Daltons. The depolymerized guar most preferably has a polydispersity of less than about 3.0 and is useful in oil well fracturing to enhance oil production.

  • Publication number: 20110021101
    Abstract: An aqueous binder composition is provided that includes a modified starch and a silane coupling agent, and optionally, a crosslinking agent. The starch from which the modified starch is derived is natural in origin, biorenewable, and is derived from plant sources. The modified starch has been chemically modified from its natural form and may have a degree of polymerization from about 20 to about 4000. Additionally, the modified starches have a low viscosity and cure at moderate temperatures. Advantageously, the modified starches are water dispersible and have excellent resistance to water after curing. In addition, the binder has a light color after being cured. The crosslinking agent may be any compound suitable for crosslinking the starch based compound. In exemplary embodiments, the silane coupling agent is an aminosilane. The environmentally friendly, biorenewable binder may be used in the formation of insulation materials and non-woven chopped strand mats.
