Innovative Aluminum Flat Solar Collector

The most important feature of this solar collector is the technical solution where the heat-absorbing surface is the same as the heat-transferring surface, which results in the highest heat performance and efficiency. There is no mediatory unit between the heat-transferring surface of the absorber and the...

Portable Diagnostic Scanning Systems for Remote Environments

A company seeks miniaturized (less than 50 lbs.) portable equipment to perform magnetic resonance imaging (MRI), computerized tomography (CT), X-ray, and other non-ultrasound diagnostic scans. The equipment must produce a minimum of ionizing radiation and is intended for medical care...

Tech Needs
Printable Electrical Heating Element or Film Bonded to Metal Surface

A firm is seeking materials that can be printed, sprayed, or transferred onto a metal surface (copper, stainless steel, brass, aluminum, nickel, chrome) as a film so that, when connected to a power source, become hot and heat the metal surface to ~400 °F. The heating film or...

High-Temperature, Ceramics-Based Composite Material

This invention is a manufacturing process of a high-temperature, ceramics-based composite material that features excellent heat and oxidation resistance and frictional properties. The composite material is a dense SiC-infiltrated composite material, a dense carbon-fiber-reinforced...

Tech Needs
Ammonium Probe-Type Sensor for Biofermentation Process Monitoring

A company seeks a probe-type ammonium sensor that can stand up to high temperatures and pressure during the sterilization step for fermentation, and that can deliver real-time concentration information during fermentation. The fermentation processes used require up to 60 hours to...

Tech Needs
Anti-Fouling Technologies for Hard Surfaces

A company seeks components to make up one or more systems that can remove surface contamination (biofilms), lime scum, and lime scale buildup; ameliorate water hardness, mold, mildew, and similar spores; and handle soap scum and remove surface detritus from a variety of materials. These components...

Innovative Aluminum Flat Solar Collector

A new flat solar collector features a heat-absorbing surface that equals the heat-transferring surface, resulting in high-heat performance and efficiency. There is no mediatory unit between the heat-transferring surface of the absorber and the heating agent. This means no galvanic corrosion, which would...
