Solar-Based Hydrogen Generation Technology

A company seeks to increase the efficiency of solar-based hydrogen generation systems by device technologies that can help to develop a new module with at least 16% solar energy utilization efficiency. Examples include the Z-scheme method and tandem type, which has achieved a Solar Energy Utilization Efficiency of 4.5% and 12.4%, respectively. Of particular interest are research organizations such as universities, and venture organizations that work jointly with them.

Making Metal Packaging Lighter

Because of increasing cost pressures on high-volume metal packaging, a manufacturer needs to make each unit weight of metal (steel and aluminum) go further. Technologies are sought that make metal packaging lighter and enhance the physical performance (like tensile strength, stiffness, etc). This could include, for example, improvements brought about by “dimpling” the metal surface and other macro surface modifications.

High-Birefringence Optical Material

A high-birefringence optical material suitable for implementation in optical systems is sought. This material has several qualities of interest beyond high birefringence: high hardness, making it amenable to standard polishing and manufacturing processes; low CTE (coefficient of thermal expansion); low CTRI (coefficient of thermal refractive index); low absorption at 1.55 micrometers; and reasonable bulk density. A material is sought that can be processed and handled using standard techniques.

Freshness Indicator for Consumer Packaging

A technology is sought that indicates that a product packed into a rigid metal container has not been tampered with and/or degraded over time. The solution must incorporate a method of communicating this information to the packager, retailer, or consumer. After packaging, and depending on the product, the container may be subjected to a thermal treatment, to a maximum of 130°C for an hour for some canned foods, or a 90°C pasteurization treatment for some beverages.

High Performance Single Crystal Piezoelectrics

The new single crystals offered here possess exceptional properties and are poised to revolutionize piezoelectric materials applications. In addition to strain levels exceeding 1% (usable strain: 0.5% at 35 kV/cm), these crystals exhibit five times the strain energy density of conventional piezoceramics. Thus, unlike piezoceramic actuators that employ strain magnification schemes, single crystal actuators can deliver higher strain levels without sacrificing generative force. The high electromechanical coupling of the proposed crystals (>90%) increases transducer bandwidth, resulting in greater sensitivity and acoustic power. In addition, low strain hysteresis results in improved high power efficiency, and lower acoustic impedance than piezoceramics allowing for easier matching to air or water. High coupling also leads to dramatic improvement in passive vibration damping.
