Palladium Membranes Separate Hydrogen

Compared to conventional technology, palladium membranes offer an increased flow of high-purity hydrogen from a gaseous stream. The membranes are prepared by electroless- deposition plating of Pd (or Pd alloy) on a porous support. The process results in a unique hexagonal structure. High flux translates to smaller separators or lower cost for the same purity of hydrogen.

Delivery of Antiseptic/Antimicrobial Formulation

A company must deliver a measured amount of antiseptic/ antimicrobial formulation to a specific surface area (between 1 to 3 square feet) and be able to verify visually that the area has been adequately covered and treated. Currently, the antimicrobial formulation is a liquid with a viscosity approximately that of water. Methods must maintain the sterility of the unused product until its outer protective packaging is opened. Data must also show the efficacy of the application method, including improved completeness of coverage, depth of penetration, or ease and simplicity of use.

Reduction of Liquid Temperatures in Metal/Glass Containers

Beverages, when served cold, quickly heat up during consumption. A client seeks material and process technologies that will insulate against heat gain or actively reduce temperature of liquids contained in glass bottles or metal cans. Processes that enable the printing, coating, and spraying of foam-like or phase-change materials are also of interest. Potential solution areas include insulation materials, aerogels, cooling hydrogels, and foaming polymers. The material must not be more than 250 microns thick.

Microfluidic System Moves Liquid Without Electricity

Many new devices need to move nano- and micro-scale quantities of liquid from an external source to a sensor. Technology has been developed to transport very tiny volumes of liquids without the need for electricity or other external energy source. The device is especially useful when surface forces overcome the flow in channels, or when high-precision control of rates and volume are needed. The surfaceenergy gradient coating technology produces enhanced capillary action in nano-scale plumbing to move and mix liquids, and to introduce chemicals or biologics for reactions.

Software Recognizes Amblyopia in Early Childhood

In developed societies, amblyopia (i.e. lazy eye) is a leading cause of permanent vision loss under the age of 30. A research team implemented an electrophysiological method that recognizes the presence or lack of binocularity in children as young as six months of age. The method is also capable of identifying other childhood visual disorders that may potentially lead to amblyopia after age 3.

Preservation of High-Water-Content Fruit

As fresh produce undergoes a number of processes from point of harvest to final products like yogurt, ice cream, pasta sauces, and frozen meals, its natural characteristics are altered. To ensure a fresh taste and texture, a company seeks technology, ingredients, or processes that preserve the natural characteristics of fruit or vegetables throughout processing. Solutions that enable frozen fruit or vegetables to have soft, fresh-like texture, appearance, color, and flavor characteristics are of high interest. Potential options include alternative freezing processes, partial dehydration/drying, water content modifiers, and ingredients or coatings to encapsulate structure.

Removal of Kinetic Energy Associated with Transporting Light

A client seeks innovative ways to control the kinetic energy of moving products through high-speed manufacturing and filling processes. The company requires aluminum and tinplated food and beverage cans to be conveyed and transported during production without damage. Products are small (40-70 mm cylinder diameter), thin (wall thickness of ~100 microns), lightweight (
