Methods of producing a multiferroic thin film material. The method includes the steps of providing a multiferroic precursor solution, subjecting the precursor solution to spin casting to produce a spin cast film, and heating the spin cast film. The precursor solution may include Bi(NO).5HO and Fe(NO).9HO in ethylene glycol to produce a bismuth ferrite film. Further, the thin film may be utilized in varied technological areas, including memory devices for information storage.

An improved substrate for growing mono-layers of adherent-type cells and methods of growing tissue structures, ex vivo. The improved substrate, which comprises a silicon substrate coated with a photo cleavable polymer, releases adherent cells non-enzymatically. Also disclosed are methods for assembling complex layers of cells of various types.

Methods of tissue engineering

Iodoisocyano, iodourea and oxazole modified 1,3 dioxep-5-ene ring monomers are synthesized and used in copolymerization reactions with trioxane to produce acetal copolymers with backbone functional groups. The invention also concerns processes for the production of acetal copolymers containing iodourea and oxazole functional groups from acetal copolymers with backbone double bonds.

(Iodo-urea and iodo-isocyano) dioxepane trioxane copolymers

Acetal copolymers of trioxane with epoxy functional groups are obtained by copolymerizing trioxane with 5,6-epoxy-1,3-dioxepane. The epoxide group in the polymer chain provides a highly reacting functional group for further modification. Acetal copolymers with backbone epoxide groups exhibit toughness and thermal stability. The backbone epoxide groups can also be aminated in a one step hydrolysis-amination process.

Acetal copolymers with backbone epoxide functional groups

The invention concerns a method for producing an acetal copolymer containing backbone bromo-functional groups comprising copolymerizing trioxane with 5,6,-dibromo-1,3-dioxepene. The invention also concerns methods of modifying acetal copolymers containing bromo-functional groups and the copolymers produced by the methods of the invention.

Acetal copolymers with backbone bromo functional groups

Acetal copolymers of trioxane and 1,3-dioxep-5-ene having a high degree of crystallinity and specific mole percent incorporations of 1,3-dioxep-5-ene are synthesized. The invention also provides a process for producing highly crystalline acetal copolymers by copolymerizing triozane and 1,3-dioxep-5-ene and precipitating the copolymer product from solution. The copolymers show much improved stability against halogen degradation.
