Abstract: Edible synthetic padding material is provided for mice and/for rat in laboratories. The edible synthetic padding material includes a major ingredient, a minor ingredient and adhesive. The major ingredient is made of edible natural fibers. The minor ingredient is made of nature elastic fibers. The adhesive is used to bond the major and minor ingredients.

Abstract: A new antifungal formulation is provided. The present invention uses a sterol modified with polyethylene glycol (PEG) as a drug carrier. The drug carrier encapsulates Amphotericin B (AmB) by self-assembly to form polymeric micelles. The polymeric micelles can reduce toxicity of Amphotericin B and control release of Amphotericin B. The polymeric micelles of Amphotericin B are used as a new antifungal formulation.

Abstract: A new method to form a floating gate for a flash memory device is achieved. The method comprises forming a first conductor layer overlying a substrate with a gate dielectric layer therebetween. A masking layer is deposited overlying the first conductor layer. The masking layer is patterned to expose first regions of and to cover second regions of the first conductor layer. A plurality of first concave surfaces are formed on the first conductor layer first regions. The masking layer is removed. A plurality of second concave surfaces are formed on the first conductor layer second regions. The first conductor layer is patterned to form floating gates. The interfaces between the plurality of first and second concave surfaces form vertical tips on the floating gates. A method to form an electron emitter is also disclosed.
