Hydrogels intended for orthopedic applications, including repair and regeneration of cartilage, bone, joint surfaces and related tissues, must possess greater strength and toughness than hydrogels used in soft tissue repair. A hydrogel formulation is provided which has high strength, toughness, a suitable mechanical modulus and low equilibrium hydration. It may also have controlled porosity or degradation time. It can be made to polymerize in situ with high (“good” to “excellent”) adherence to target tissue or surfaces. A preferred formulation for forming such gels comprises 40 to 80% by weight of a low-molecular weight polar monomer and 30 to 10% of a hydrophilic macromeric crosslinker.

The present invention relates to thermoplastic materials which are anaerobically degradable in an active sewage sludge. These materials are melt processable into fibers, films or laminates, and are suitable for use in an absorbent article, particularly flushable interlabial products, tampons and pantiliners.

This invention provides novel high density memory devices (FIG. 3) that are electrically addressable permitting effective reading and writing, that provide a high memory density (102), that provide a high degree of fault tolerance, and that are amenable to efficient chemical synthesis and chip fabrication. The devices arc intrinsically latchable, defect tolerant, and support destructive or non-destructive read cycles. In a preferred embodiment, the device comprises a fixed electrode electrically coupled to a storage medium having a multiplicity of different and distinguishable oxidation states wherein data is stored in said oxidation states by the addition or withdrawal of one or more electrons from said storage medium via the electrically coupled electrode.

A method of making a multi-layered composite material having a layer of a first metal and a layer of a second incompatible metal, separate from the first metal, the method involving hot rolling a multi-layered assembly of the first metal; the second metal; and a composite interlayer between the first metal and the second metal; wherein the composite interlayer having a first outer layer of a first composite metal compatible with the first metal; a second outer layer of a second composite metal compatible with the second metal; and an interlayer metal bonded between the first composite metal and the second composite metal; and wherein the first metal is adjacent the first composite metal and the second metal is adjacent the second composite metal; to effect production of the multi-layered composite material. The invention is valuable for producing a bonded composite of a hardened steel, such as an armour steel, with GA14V titanium.

Disclosed is a polyester resin composition for a covering material of a cable. The present invention provides the polyester resin composition for a covering material of a cable including a polyester resin as a base resin, including 0.1 to 4 parts by weight of amide-based wax as an internal lubricant, based on 100 parts by weight of the polyester resin as the base resin. The polyester resin composition according to the present invention has advantages that the resin may be uniformly and completely melted using only the general equipments such as an extruder with an L/D ratio of less than 30 and a single-stranded screw without an additional investment for equipments, and also has such an improved processability that protrusions are minimized upon forming a covering layer of a cable, as well as an excellent mechanical properties such as tensile strength, elongation, etc.

The high dissipating precipitated silica reinforced EPDM rubber (monomer of ethylene-propylene-diene) and a colored extruded polymeric profile including the formulation, are particularly intended for use in the building and automobile industry. The process for the manufacturing the formulation for reinforced EPDM rubber, includes the use of one or more EPDM polymers, at least one high dissipating precipitated silica as a reinforcing filler, a non-reinforcing filler, an antioxidant, an interface agent and/or coupling agent, a desiccant, an accelerating activator, and vulcanization additives.

This invention provides a new method of forming a self-assembling monolayer (SAM) of alcohol-terminated or thiol-terminated organic molecules (e.g. ferrocenes, porphyrins, etc.) on a silicon or other group IV element surface. The assembly is based on the formation of an E-O— or an E-S— bond where E is the group IV element (e.g. Si, Ge, etc.). The procedure has been successfully used on both P- and n-type group IV element surfaces. The assemblies are stable under ambient conditions and can be exposed to repeated electrochemical cycling.

An acoustical tile including: 8 to 25 wt % mineral wool, 9 to 15 wt % starch binder, 9 to 15 wt % cellulosic fiber, wherein preferably the cellulosic fiber is newsprint, and 40 to 65 wt % perlite, wherein the weight ratio of the starch to the cellulosic fiber is 0.6 to 1.3:1; and a process for making the acoustical tile.

A placeholder for vertebrae or vertebral discs includes a tubular body, which along its jacket surface has a plurality of breakthroughs or openings for over-growth with adjacent tissue. The placeholder includes at least a second tubular body provided with a plurality of breakthroughs and openings at least partially inside the first tubular body. The first and second tubular bodies can have different cross-sectional shapes, can be are arranged inside one another by press fit or force fit or can be connected to each other via connecting pins and arranged side by side to one another in the first body.
