Transformer Fluid
This biodegradable non-toxic transformer fluid based on polytrimethylene ether glycol homopolymer is derived from natural and renewable sources and directly replaces non-biodegradable mineral oils that may contain hazardous compounds. The DuPont technology results in a transformer fluid that is highly stable and offers equal or superior functionality compared to current fluid materials. Fluid breakdown is a major cause of transformer failures. This transformer fluid offers long life and no changes in chemical properties over the life of the transformer, while inhibiting corrosion, oxidation, and water absorption. The fluid is compatible with polymer and resin sealant chemistries and materials, and with insulating materials used in transformers. It can be formulated in a wide variety of configurable chemistries to meet various needs. For example, flash and flame points are adjustable. Commonly used fluids have a flash point of about 180 degrees C; the DuPont technology offers a flash point of 200 degrees C, and can be adjusted higher. It is particularly suited to cold-climate service, with a low pour-point that also is adjustable. DuPont is offering the IP and technology to convert bio-PDO material into transformer fluids. The broad patent claims include the fluid and transformers using the fluid. DuPont can produce laboratory-scale samples for testing under the appropriate agreements.

Synthetic leather material with a touch-feel superior to high-quality natural leather and durability better than synthetics
SOFILEZ is a synthetic leather material developed by Nissan that delivers a touch-feel (or hand) superior to the high-quality natural leather used in apparel and furniture applications, but that is also more durable than existing synthetic leathers. Nissan engineers based their design on the way the human fingertip interacts with surfaces along four different axes of material properties. The fingertip determines whether a surface is soft or hard, smooth or coarse, wet or dry, and warm or cold. By discovering the relationship between the fingertip and the sensations produced by feeling high-quality hide-based material, Nissan engineers set the appropriate physical properties for the SOFILEZ material. People sense the greatest comfort, and the feel is most similar to high-quality leather, when the interval of salient materials is closest to that of the fingerprint. Nissan uses the material in its high-end FUGA automobile (sold as the Infiniti M in North America) for high-touch areas such as the armrest and door panels, where the touch of the product is important but durability is critical. The material is available from Nissan in quantity and in any color.

Piezo-electric actuated valves for process control systems offer 10X greater control accuracy and repeatability
Parker-Hannifin's PACE Hf miniature ultra-high-flow, low-power proportional valves for inert and non-corrosive gases to control other valves and processes downstream, or act as valves in their own right. They are based on Parker's Viva piezo electric actuators to deliver optimal control in a miniature, low-power, high-flow package. The PACE-Hf (High flow) will deliver 180 slpm (standard liters per minute) while consuming less than 1 watt of power. It becomes the ideal solution for applications requiring low hysteresis and fast response. Additionally, the PACE-Hf valve has internal capability to operate as a closed loop control valve via input sensor directly to the valve. This allows for real-time pressure/flow control. The Viva piezo electric actuator inside the PACE Hf provides high repeatability and accuracy for the valve: 0.25% variability in 10ms cycle times (where conventional valve actuators maintain only 20-30%). PACE Hf should be considered where proportional operation, low power consumption, low heat generation, long life, and fast response are important. The devices offer precise actuation at extremely low current drops - 6.8V at 1.5mA - so that a single bus can operate multiple control valves. In some installations, as many as 16 devices can operate from the same bus, which reduces the overall processing system costs and allows process control "Christmas trees" to be placed inside an intrinsically safe or sealed environment. The device is ideal for applications requiring rapid response and repeatable hysteresis (5 msec typical) in closed-loop applications, and digital compensation makes it ideal for applications requiring tightly controlled hysteresis (15 msec typical), or use in open-loop applications. The PACE Hf offers a wide control range under varying inlet pressures up to 100 psi.

Biodegradable silica gel fiber technology for wound care, hard and soft tissue regeneration, and drug delivery
SGF is the first inorganic, biodegradable fiber with wound-healing properties. It is suitable as a platform technology for hard and soft tissue regeneration (cartilage/bone), as well as for drug delivery and tissue engineering. SGF development has demonstrated during pre-clinical phase (in-vitro and in vivo) as well as in clinical trial promising potential to improve healing with excellent tolerability, safety, and no toxicity profile. The first product is approved in Europe as CE (IIb) and can be launched immediately. A 510(k) registration is possible in the US. The technology offers a unique, bio-resorbable scaffold for several applications in regenerative medicine, with an initial focus on chronic wound management. SGF acts as a physical scaffold to aid the growth of new cells and the collagen structure that supports them. As a scaffold, it can be used to deliver drugs over a wide area to aid in healing. The material itself is inorganic, but is integrated into the tissues and resorbed by the body. Unlike collagen, the SGF scaffold stayes in the wound for 1-2 weeks before resorption SGF is progressively resorbed and replaced by new tissue during the healing process. Dimension (thickness and size) as well as degradation speed can be adjusted from some millimeters up to several hundred square centimeter, from some days up to years. A GMP (ISO 14385)-certified production plant is also available for production.

Redesigned pixels reduce manufacturing costs of LCD and OLED TVs by allowing roll-to-roll printing
RD&IP's redesigned television pixels make it possible to manufacture large-size HDTVs by using cost-effective roll-to-roll printing. The new pixel technology can substantially reduce the cost of manufacturing and increase panel yield. Using a printing process to make televisions is much more cost-effective than using a photolithography process. However, such printing processes have not been widely adopted because printed transistors often do not have fast enough switching speed. RD&IP's invention bypasses this technology limitation with redesigned television pixels appropriate to the per-inch pixel density of large-size high-resolution televisions (60 inches and larger). RD&IP's technology enables organic transistors on a flexible substrate and manufacturing the LCD or OLED using a roll-to-roll printing process. There are immediate applications to lowering the manufacturing costs of present-day consumer LCD televisions. Large-size HDTVs can now be made with amorphous silicon transistors using low-resolution shadow-mask technology. RD&IP's technology also enables mid-resolution LCD displays of good uniformity without using any transistors in a pixel. Such mid-resolution LCD displays can have potential industrial applications where the LCD must be made as cheaply as possible.

Production of bio-plastic using biodiesel waste glycerol
An effective bio-plastic production technology was developed using waste glycerol, obtained as a by-product of biodiesel fuel (BDF) production. - Waste glycerol can be directly used as a carbon source to produce biodegradable bio-plastic i.e. polyhydroxyalkanoates (PHAs). - Halomonas sp. KM-1, which was isolated in our institute, can produce PHAs of more than 0.5 g per L-culture per hour from waste glycerol without sterilization or a control of pH.

Seeking: Manufacturing methods to deposit a consistent and even layer of inorganic material on a large metal substrate
We are depositing substantial quantities of material using physical vapor deposition techniques on a large metal substrate. We are seeking alternative methods to enable the creation of a thick layer of material, more effective vapour deposition techniques, or better and more precise ways of preparing crucibles for the vapour deposition process. We are open to all solutions that produce a high-yield, high precision method of depositing the thick layer of salt on the metal substrate with reproducible results. Reduction in cost of production (or increase in quality and production rate) would be a plus. A relatively thick layer of an inorganic salt - between 400 and 500 micrometers - must be deposited on a metal substrate with microscopic evenness and regularity. Substrates measure up to about 60 centimeters in diameter. These substrates require a substantial amount of the salt. Currently, up to a kilogram of a salt of an alkalihalide is melted electrically in a tantalum crucible within a vacuum chamber, and the vapor is deposited on the metal substrate. The crucibles are folded from a sheet of tantalum. The folds and the electrode attachment points of the crucibles are not consistent. As a consequence, the resistance, conductivity, and heating patterns of each crucible, and the vapor cloud it produces, varies from crucible to crucible, and the pattern of the cloud changes over time as any one crucible ages. We would like to discover a high-yield, high-precision method of depositing the thick layer of salt on the metal substrate with reproducible results. This method may be vapour deposition, as we are currently practicing; but we are open to other suggestions and methodologies. It is the high-quality end-product that we are after. If we continue with vapor deposition, maintaining the quality and consistency of the vapour cloud is of paramount importance, which may require higher-quality crucibles.

Seeking: Halogen-free fire retardants for cables that produce minimal smoke/fire, and could meet UL cable-burn testing criteria
This organization wants to find a material that will make cabling fire-retardant. The material must contain no halogens, and must eventually meet UL testing requirements. They want to explore a variety of ways to achieve non-halogenated fire retardancy on cabling that may pass standards tests, particularly tests that involve fully constructed cables (along with their wiring and insulator materials). Underwriters' Laboratories (UL) is one of the main standards organizations that imposes a set of tests on fire-retardants in the US. Technologies that may not yet have passed UL testing are definitely of interest. Methods of imparting non-halogenated fire retardancy to cables may include: o Compounds o Coatings o Polymers o Additives. Your proposed solution should have minimal impact on the physical properties of the resultant cable, and offer good processability. UL tests of particular interest include UL-94, 1581, 1685, 1666, as well as their IEEE versions (for example, IEEE 383). Solutions capable of passing European IEC 60332-3 may also be suitable. Finally, though it is not believed possible at this time, a solution capable of passing NFPA 262 would be of high interest. The proposed solution found should not negatively affect other properties required by UL to a level that prevents successful commercialization, and have reasonable permanence.

Seeking: Deposition of Surfactant Soluble Materials on Skin
The delivery of actives onto skin through rinse-off products is extremely challenging. Surfactant soluble actives (e.g. perfumes) present additional challenges for the deposition from body wash. They tend to be rinsed off with the surfactant resulting in deposition efficiency much less than 2%. Our objective is to provide the delivery of surfactant soluble actives onto body skin with deposition efficiency or 15% or higher. Constraints include: Lather volume is one of the important in-use properties that consumers value. The additives to body wash for deposition enhancement often decreases lather volume. Minimizing lather negatives is critical to the success of any new delivery technologies. New technologies should not have negative impact on stability. For encapsulation related technologies, long term stability of active diffusion in and out of the capsules needs to be well understood. The low cost structure of body washes requires high efficiency for new additives. Generally, the material cost should be less than $30/kg. Any new additives should be safe for human daily use following standard safety measures, such as irritation, adverse reactions, inhalation and microbe, etc. The partner should have a good mechanistic understanding of their deposition technologies and experimentally demonstrate deposition efficiency improvement and should have knowledge and capabilities in synthesis and characterization of any new materials.

Seeking: Approaches for functional group protection against enzyme-catalyzed inactivation either by oxidation, reduction, hydrolysis or conjugation reactions
We are looking for non-covalent protection approaches against chemical and/or biological inactivation reactions. Our focus is on the prevention of inactivation of actives resulting from enzyme activity. A common example of enzymatic inactivation reactions is the process of microbial degradation. The primary microorganisms responsible for microbial degradation are fungi and bacteria that use the carbon, nitrogen, hydrogen, and sulfur components of chemical compounds as energy substrates, in some cases exclusively. We are seeking to circumvent microbial degradation reactions through the use of chemical protecting groups or biocides, which alter chemical compounds' susceptibilities to inactivation. o The protective groups/agents should not further alter the chemical characteristics of the compound. o They must be environmentally benign and non-toxic. Among the approaches you may wish to consider are active chemistry protection via encapsulation with secondary chemistries, compositions including chemistries designed to otherwise mitigate microbial degradation, or other protecting technologies. A successful proposed solution will prevent enzyme-caused inactivation reactions for our products in the field. It will be novel, proprietary, and patented (or potentially patentable).

Seeking: Rheology modifiers stable at high pH in the presence of divalent ions
We are seeking rheology modifiers stable to high pH systems (pH 10 to 13) are an area of interest. Looking to purchase and/or obtain samples of a broad/diverse library of rheology modifiers stable in high pH systems (pH 10 to 13) in the presence of divalent ions (specifically Calcium). A potential partner should have general organic synthesis knowledge as well as access to a broad/diverse chemical library. Constraints: o The rheology modifier must be capable of forming a significant yield stress. o The rheology modifier must be resistant to syneresis effects, yet not excessively bind water. o Ideally, we seek a rheology modifier that does not require neutralisation nor acts as a buffer and builds the required structure immediately.

Seeking: The next generation in microfiber cleaning cloth technology
Microfiber cloth has revolutionized the cleaning industry. The cloth's ability to trap dirt and allergens is no less than amazing. We are looking for a product or technology that would build off or increase microfiber's strengths, such as: 1. An additive, treatment or technology that would increase the absorbency of the microfiber cloth. 2. A technology that increases microfiber's ability to pick up and contain microbials. 3. A technology that would aid in releasing the trapped allergens and dirt on demand. 4. The technology will obsolete microfiber. We would like to find a range of methods or technologies filling this need. The company is open to licensing arrangements.

Seeking: New product opportunities around our recycled rubber crumb material
We are seeking partnering and investment opportunities in the tire recycling sector. We are particularly seeking new product opportunities where our recycled rubber crumb material can be a significant component. Opportunities may include, but should not be limited to, the following markets: o Filtration, e.g. membranes / activated carbon o Temporary flooring / interior materials for events and exhibitions o Absorption of energy / sound / impact / odor o Seals / closures / gaskets o Consumer products o Composite products o Drainage o Inert fillers / pigments o Energy generation. We are interested in these areas and others, where the inherent properties of the rubber crumb can be utilised (e.g. calorific content, elasticity, flexibility, porosity, inertness, etc). We will consider niche opportunities across a diverse range of products, markets and applications. We are keen to find opportunities for markets outside the construction / landscaping industries where rubber crumb is currently used, and is considered a commodity product.
