Self-healing Slide-Ring Material paint makes fine scratches disappear on mobile phones,laptops, other surfaces
Ideal for mobile phone applications, laptop cases, and similar devices that suffer continual minor scratching and abrasion in pocket, backpack, and purse, Slide Ring Material (SRM) paint is able to heal about 80% of surface abrasions by itself, almost immediately. The coating is already commercialized in Japan. The product comprises polymer chains that freely slide through the cross-linked molecules, forming a supramolecular network. When disturbed by minor abrasions, the cross-linked molecules retain mobility and the coating redistributes its tension to "slide" back into place along the polymer chains, erasing the abrasion. Chemically, the coating is an oleophilic polyrotaxane. Its solubility and ability to react with curing agents make it highly applicable to coating resins. In operation, the paint resists cracking and peeling, offers improved elasticity and impact resistance, and is unsusceptible to fouling and adhesion. SRM covers the same square area as other paints with a similar solids component, but against competitive anti-scratch coatings of similar anti-scratch resin ratio, SRM produces a superior anti-scratch effect with a thinner coating. Compared to other anti-scratch coatings: SRM is less temperature dependence, anti-scratch performance degrades less with age, and offers higher yield. Re-coating is practical. A coating of several micrometers thickness can be spray-applied at a high dilution rate.

Trimethylene carbonate polymers and copolymers for biomedical and coatings applications
This technology includes processes for trimethylene carbonate (TMC) polymerization and copolymerizations. Our synthesis technology produces pristine TMC polymers and copolymers -- free of the trace metals residue from currently practiced synthesis using organometallic catalysts. This technology utilizes acidic ion exchange resin catalysts in the presence of a solvent instead. This metal-free feature is critical for biomedical end-uses such as synthetic sutures. Copolymerization of TMC with poly(trimethylene ether)glycols produces elastomeric properties that are useful in personal care, coatings, and lubricants. Because of the inherent features of fibers made from TMC and its copolymers with other lactones, one can design appropriate degradation rates for a wide variety of end use applications. The copolymers can be designed to degrade in vivo in less than 1 month to well over a year. One consequence of being able to dial in a degradation profile would be the creation of fibers that can be fashioned into mesh constructions with elastic properties that would make the meshes appropriate for applications such as hernia repair or any wound repair to tissue that requires flexibility for optimal healing. This is something that is not easily afforded by other products on the market today.

Method for screening catalytic non-enzyme polypeptides and proteins
The present invention relates to the direct screening of hybridoma supernatants or other potential sources of catalysts for catalytic activity, and more particularly to a method for screening or detection of non-enzyme catalytic polypeptides and proteins, including catalytic antibodies. Catalytic antibodies are elicited against a hapten, typically, a stable synthetic analog of the transition state (TS) of the catalyzed reaction. The repertoire resulting after immunization is immortalized as hybridomas, which are then screened to select those clones producing monoclonal antibodies that bind the hapten. The initial screening of the hybridomas is by binding assays of the antibody to the hapten. Those hybridomas are then propagated and checked for catalytic activity. This conventional approach does not identify antibodies that bind weakly to the hapten, although they may have the desired catalytic activity. In addition, this approach is time consuming and wasteful of materials. The current invention provides a more effective mean of screening hybridomas. In this method a preparation containing the potential catalyst is contacted with the substrate S immobilized to a support and the immobilized product P obtained is detected. Detecting catalytic activity directly in the supernatent is more precise and efficient than the current methods.

Easily recoverable, arbitrary proteins produced by recombinant host cells
This strain of Rhodococcus acts as expression vector for one or more foreign genes simultaneously, to express one or more recombinant proteins in the host cell. Because this strain of Rhodococcus has a higher sensitivity to lysozyme and undergoes lysis more easily than does the wild strain, recombinant protein is more easily recovered. The cells can proliferate and express proteins at temperatures lower than can E. coli; thus proteins can be produced that would be inhibited by the other host's higher temperature requirements. Applications already include production of proteins that undergo a conversion reaction and that can decompose environmental pollutants. Purpose-designed proteinic production using Rhodococcus is already under study in Japan as a method for decomposing environmental pollution by making proteins that undergo a conversion reaction.

A polarization mode dispersion (PMD) emulator with tunable first-order PMD and a constant second-order PMD for emulation of PMD in optical network systems
Our partner, a South-African University, has developed a novel technology to emulate first- and second-order polarization mode dispersion (PMD) in optical fiber networks and other applications. They would like to discuss this novel technology with potential partners who already sell emulators and other related equipment and who may be interested in adding value to their existing portfolio of products using this technology. The technology owner is interested in the following co-operations: licensing, sale, or investment. The emulator comprises of a sub-emulator (made up of cascaded PMF segments), a computer controlled polarization controller and an optical delay line.

Seeking: Methods that detect contaminants, microbes, or general cleanliness on hands, surfaces, and the environment
We are seeking methods that detect contaminants, microbes, or general cleanliness in the air, on hands, in water, on food, on surfaces, and in similar situations so that consumers and commercial users can clean more thoroughly and feel confident that they have eliminated the problem. Most people take cleaning as a matter of faith. They wash, wipe, mop, and swab and assume that the apple, the countertop, the cup, the linoleum, and the sink are clean. They sniff the air and inspect the toilet. But they don?t actually know whether they've been successful. These concerns also affect commercial cleaners in hospitals, restaurants, and similar establishments. We want to find ways to know if cleaning has been successful (or if it's currently needed), and our interest goes beyond the countertop. For example, is there lead or mercury in the tap water? Is there mold, dander, pollen, or other allergens in the air? Are the dishes in the dishwasher fully sanitized? Is there salmonella, E. coli, staph, strep -- or worse, MRSA or C. difficile -- on a surface? Learning that contamination exists is part of the problem; confirming that it has been eliminated is the other. Combined solutions that can both detect and eliminate contaminants are of high interest.

Seeking: Innovative and cost-efficient biocidal packaging
While there is no doubt about the efficacy and cost-effective advantage of classical biocide and preservation approaches, there is also an increasing market trend of consumers looking for products that are preservative-free or that use alternative preservation approaches. In addition, many of the traditional preservation technologies are increasingly involved in external relations, regulatory, and environmental/sustainability issues. New alternatives to replace these traditional microbial control tools are needed in order to provide our consumers with what they want and to minimize the potential business risks associated with their continued use. You will need to demonstrate antimicrobial activity against specific pathogenic microbes and, if possible, against selected environmental isolates; and offer sufficient data to allow consumer exposure for product testing (short and long term). Ideally, we will find polymeric materials that can protect the biocidal agent from rapid degradation and facilitate the controlled release of the biocidal active during the lifetime of the product. Materials should ultimately have global regulatory approval for the different applications.

Seeking: Leak-proof disposable food storage
We are interested in a food safe plastic packaging container that is ready for market by 7/2011 and has a leak proof twist-top seal. Requirements include: Ready for market by 7/2011; Cost per unit/tub needs is < $0.40 USD; Screw top like closure which is liquid leak proof; Multiple sizes ranging from 200ml to 500ml; Microwaveable and dishwasher safe (hot and cold temps); Plastic material can be more disposable vs. durable (thinner gauge vs. thicker). We would also request a photo and specifications of the container(s) either already in market or in development for market. This project is at the search stage. Our interest is to find existing food storage containers that fit or get close to the requirements. Following initial assessments from the submitted information, we would request a small sample supply to allow for actual usage/function assessment.

Seeking: Post-processing of molecular dynamic solutions
We use a variety of computer simulation methods to study the structure and dynamics of complex mixtures from the atomistic to colloidal length scale. Ingredients to formulations typically include surfactants, polymers and colloids. Using simulations, we can study how molecular structure and composition affects the microscopic structure (10nanometers-100micrometers) and dynamics in formulations which in turn determines the macroscopic properties and performance of our products. The objective is to accelerate formulation development and gain detailed insight into the effect of formulation levers. Input variables to our simulations typically include composition and process levers; the output is a trajectory of molecules interacting and forming complex aggregates differing in size, shape and topology. Our capabilities to extract information from raw simulation data is limited by the information we can extract from the trajectories. We are assembling a large set of descriptors (fingerprints) for macromolecular aggregates found in dynamics simulations to quantify the response in the microscopic structure and dynamics to the change of input variables. The intended area of use for these descriptor lies both in discovery oriented studies, i.e. to explore new compositional-structural relationships, as well as in building empirical models which relate to macroscopic observables.

Seeking: Geothermal power plant technology
We are looking for Experts/Organisations in the field of Geothermal Energy to provide services to an upcoming 2X25MW geothermal Power Plant in India. The Consultancy Assignment is to provide complete techno-economic feasibility, technology, and operational expertise.

Seeking: Packaging for developing/low-income markets
We are interested in evaluating packaging technologies for developing/low-income markets that enable a better consumer experience than current approaches and which are sustainable and low-cost. Low-income markets have different packaging challenges than do developed markets, for example, product volumes are typically much smaller, the use environment is often outdoors, shipping and handling methods can be much more aggressive, disposal methods are not as controlled, and sensitivity to price is much higher. Possible Approach(es) might include: Package designs that can be reused by the consumer for another purpose; Materials that are from renewable resources; local sourcing of materials is an added bonus; Refillable/durable packages that last more than 100 or more uses; Materials or packages that are consumed (dissolved, for example) during product use; Edible packaging materials; Packaging materials that contain or act as fertilizer. We are not interested in additives that make traditional polymers biodegradable or oxodegradable and do not meet the constraints regarding biodegradable polymers or Toxics in Packaging regulations.
