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.

Highly Power-Aware Digital Extravehicular Activity (EVA) Radio

As NASA embarks upon deep-space human exploration, the next-generation extravehicular activity (EVA) radio will be a pivotal technology and an integral part of lunar surface systems success. It facilitates surface operations, enables crew mobility, and supports point to multi-point communications across rovers, landers, habitat, and other astronauts. Driven by Com - m unications, Command, Control, and Information (C3I) interoperability, stringent power budgets, and miniaturization, this mobile radio platform has become increasingly complex. To achieve the overarching communication goals of small form factor, ultrapower, and reconfigurability, NASA needs to advance power-aware processing technology.

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.

NASA Geostationary Coastal and Air Pollution Monitoring

The Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission has been recommended for launch in the 2013-2016 time frame by the National Research Council. The mission’s purpose is to gather science that identifies human versus natural sources of aerosols and ozone precursors, tracks air pollution transport, and studies the dynamics of coastal ecosystems, river plumes, and tidal fronts.

Delivery System to Modify Release of Organic Agricultural Compound

A company’s current product is applied in granular or prill form, and a coating acts to inhibit the release of the product within. The company is looking for a method to modify the release of the organic compound. The compound becomes active when it comes into contact with external reagents in the area of application. Moisture, pH, temperature, and soil types are the influencers. The solution may come in the form of encapsulation, a barrier method, or a novel mechanism that modifies the release rate of the product in granular or prill form.

Technology to Convert, Concentrate, or Dry Oil-Based Emulsions, Dispersions, or Liquids Into a Dry Powder Form

A company supplies a variety of chemicals, including inverse emulsions that consist of a very-high-molecular weight, water-soluble polymer dispersed in a continuous oil phase. The typical ratio of the key components is approximately 1:1:1 (polymer:water:oil). The company seeks to convert these emulsions to a water-soluble, powdered form, without losing any of the polymer properties. The problem is particularly difficult due to the oil in the emulsion. The oil is an aliphatic hydrocarbon with a low vapor pressure (0.023 kPa at 20ºC) and a distillation temperature of 255ºC.

Technology for Improved Performance of Release Agents in Die Casting

A materials company supplying specialty technical products to the foundry industry is seeking technology to allow a stepchange in performance of release agents/die lubricants for high-pressure die casting of non-ferrous (e.g. aluminium) components. Areas of interest include products that can be applied at a higher temperature to allow faster casting cycles, products that protect the die from damage caused by repeated heating and cooling cycles, and powder-based agents, and products that adhere quickly to steel.

In-Store Hair Analysis Tools

A company is seeking tools and devices that can be used instore to quickly classify hair types based on measured hair properties like hair thickness and/or damage level. Technologies include hair diagnostic devices/tools that can evaluate at least one of the following parameters: structure information; physical properties such as amount of curl, tensile strength, and stiffness; and cosmetic properties such as smoothness, friction, and resistance to frizz. Tools must be easy to use in-store, and results must be sensitive enough to differentiate between ranges of hair types.

Large Aperture Inflatable/Deployable Antennas and Their Role in NASA’s Vision for Space Exploration and Earth Science

As NASA evolves its vision for space exploration and Earth science, greater demands are placed on advanced communications and sensing systems to allow for higher data-rate communications from the Moon, Mars, and beyond, as well as for more precise Earth and planetary remote sensing activities. Taking into consideration the cost of launching hardware into space (about $20K per kg), as well as the fairings’ volume limitations, there is need for novel antenna technology concepts to circumvent these limitations, without jeopardizing the desired capabilities. To address this scenario, NASA is investigating the development of large aperture, inflatable/deployable antenna (IDA) technologies as a viable option to fulfill the aforementioned requirements. Attainment of these requirements demands overcoming a series of critical challenges as discussed below.
