New Systemic Chemical Insecticides

A client seeks new synthetic (chemical-based) control agents for insects such as aphids and spider mites. The piercing and sucking insects damage plants by inserting their mouthpart into plant tissues and feeding on the juices. Heavily infested plants become yellow, wilted, deformed, or stunted, and may eventually die. There is a need to pursue insect control agents with new modes of action in order to keep insecticide resistance at manageable levels. The proposed insect control agents must be systemic, broad-spectrum insecticides that have low risk to humans and the environment.

Insect Processing Technologies for Chicken Feed

The growing scarcity of resources to produce increasingly demanded ingredients, such as soybean meal and animal protein meals, has doubled feed costs in the recent years. Thus, alternative protein sources, including insects, are urgently needed. Insects must be introduced in the feed chain, and multiple quality parameters need to be taken into account: quality, availability, and cost. Expectations for new technologies include a processing method for the insect, nutritional evaluation, identification of microbiological problems, and financial evaluation to understand the viability of the business.

Low-Friction Surface for Ready-to-Use Catheter

A company seeks a low-friction surface for ready-to-use intermittent catheters for both men and women, with the goal of achieving insertion and retraction without causing any trauma or perception of trauma. The low-friction surface must operate during insertion, while the catheter is in place, and during removal. Balance between kink-resistance and flexibility is important, and the ability to insert the catheter without touching it would be ideal. It must offer 3-5 years of shelf life at ambient temperatures, and use biocompatible materlals.

Moisture Release Technologies

A company seeks technologies enabling a woven or nonwoven substrate to contain liquid/fluid that can be released by applying pressure (to yield a moist/wet substrate). They are interested in solutions that will enable water or other liquids/ fluids to be contained within a substrate and then released under moderate pressure (for example, by squeezing the substrate in your hand). The technology solution must be able to incorporate sufficient liquid content in the substrate so that when pressure is applied, approximately 75% of that substrate unit becomes moist.

Binder Solutions for the Manufacture of Molds and, Cores in Metal Castings

Binders used for molding are typically self-setting, so that after mixing two or more binder components into sand, there is a short delay before the mixture starts to set hard. Binders used for core-making are typically gas-cured. A company seeks an environmentally acceptable binder system that could be based on inorganic, “clean” organic, or hybrid derivatives, and offers an immediate advantage over current systems in terms of health, safety, and environmental issues.

Generating Sodium Hydroxide from Sodium Sulfate and Calcium Hydroxide

A company produces crystalline sodium sulfate as a byproduct, using sodium hydroxide as one of many feeds within the process. They seek to use the available compounds to produce it in situ. The company seeks a process that uses sodium sulfate and calcium oxide to produce sodium hydroxide, and could accept an aqueous product from a process with the lower limit being about 8% caustic solution with moderate sulfate content. Low calcium content in the caustic is important. The company can accept the formation of gypsum as a by-product of the process.

Manufacturing Method for Joining Elastic Materials

A company seeks methods of joining identical elastic materials. The current method is to use adhesives to bond the elastic components physically, but adhesives lack the strength of a chemical bond or weld. A method of joining or bonding natural or synthetic rubber in a way that can withstand a 25- pound tensile load is desirable. The bonded joint must retain the same cross-sectional area as the two components prior to joining. The bond joining the faces must be unaffected by moisture, temperature, and chemicals, and it must be able to withstand 500 cycles at 300% elongation.

Topical Products to Suppress Pain During Epilation

A company is seeking topically applied products and/or chemical technologies to eliminate or suppress pain sensation associated with epilation of undesired hair from skin. Pain elimination or suppression should be quick (<5 minutes) upon application on skin, and the effect should be temporary (lasting about 30 minutes), similar to topical anesthetics. Products can be in the form of liquid, gel, cream, or lotion to easily apply or spray on skin; should not have any undesired side effects on skin (irritation, itching, redness); and derived from natural sources and with herbal properties.

Crush/Cut-Resistant Safety Glove

A company seeks existing materials that can be utilized in applications for a safety glove. This material must be cutresistant, flexible, and withstand oily, wet, muddy conditions. The material covering the top of the hand and fingers must be extremely flexible and designed to protect the hand and digits from being crushed by dispersing the area of impact from the initial blow. The mold for the top area of the hand must have emphasis on complete coverage without hindering normal movement.
