Air and Moisture Removal Within Closed Containers

Many types of food spoilage are slowed when air and moisture are removed from around the food. Current removal solutions, however, are expensive, take up too much space, and require complicated processes. A new technology must remove air and moisture with the single push of a button. Any proposed device should be incorporated into the container. A previously attempted solution included a countertop appliance that, using a vacuum, sealed a bag with heat.

Biodegradable Silica Gel Fiber Regenerates Cell Tissue

An inorganic, biodegradable silica gel fiber (SGF) acts as a physical scaffold to aid the growth of new cells and the collagen structure that supports them. As a scaffold, it can also be used to deliver drugs over a wide area to aid in healing. The material is integrated into the tissues and resorbed by the body. Unlike collagen, the SGF scaffold stays in the wound for 1–2 weeks before resorption. Dimension as well as degradation speed can be adjusted from millimeters up to several hundred square centimeters.

Nozzle Produces Ultrafine Droplets

Energy-saving nozzles offer droplet sizes down to 25 microns, at operating pressures as low as 100 psi. Nozzle passages, including metering slots, spin chambers, and exit orifices, are designed to minimize pressure drop, resulting in conservation of pump energy up to the exit orifice.

NASA Medical Capabilities for Space Missions

Ensuring the health, safety, and effective performance of astronauts is critical to the human exploration of space. During missions to the Moon, Mars, or asteroids, crewmembers must have access to advanced medical technologies and protocols to prevent health problems, diagnose disease, treat injuries, and minimize illnesses that may occur in the course of a mission. The Human Research Program (HRP) at Glenn Research Center (Glenn) is seeking government, university, or industry partners to develop medical capabilities that can help to secure the health and safety of astronauts during space missions.

Increased Steel Surface Friction

An organization seeks innovative processes or coatings for steel. The application requires that a normal force be applied between two lubricated steel surfaces. Excessive normal force results in system power losses and increase in wear; the desired solution will permanently increase the coefficient of friction so that the normal force can be minimized. Solutions could be based around altering or hardening the surface of the steel, or applying a coating to the steel or another material.

Halogen-Free Fire Retardants

A company must achieve standard, non-halogenated fire retardancy on cabling. Methods may include plastic compounds, coatings, polymers, or additives. The UL tests define the fire-retardant properties that the cable must exhibit after treatment — notably, ignition resistance, flame spread resistance after ignition, elimination of burn drips after ignition, low peak smoke release rate, and low total smoke released.

Synthetic Material Offers Touch-Feel of Genuine Leather

A synthetic leather material delivers a durable touch-feel. The design is based on the way that the human fingertip interacts with surfaces along four different axes of material properties. The fingertip determines whether a surface is soft or hard, smooth or coarse, wet or dry, and warm or cold. By discovering the relationship between the fingertip and the sensations produced by feeling high-quality, hide-based material, engineers set the appropriate physical properties.

Piezoelectric-Actuated Valves Bring Accuracy to Process Control Systems

The PACE Hf, a high-flow proportional valve utilizing a Parker Advanced Technology actuator, delivers 180 slpm of air at 30 psi. The product has low power requirements: steadystate 0.6 Watts max, cycling 15 Hz, 1.2 Watts. The Viva piezoelectric actuator provides repeatability and accuracy for the valve of 0.25% variability in 10 ms cycle times.

Long-Term Data Acquisition, Command, and Control of Spaceflight-Quality Laser Systems

NASA Goddard Space Flight Center is a leader in developing satellite-based laser technology for remote sensing measurements of the Earth and other planetary bodies. Laser performance for such missions must be highly efficient and stable over long periods of time in order to successfully accomplish the desired science goals of these missions. It is therefore critical to be able to measure and control multiple laser input and output parameters simultaneously and accurately over a period of time that significantly reduces risk.

Manufacturing Methods to Deposit Inorganic Material Layers on Metal Substrates

A company seeks alternative ways of preparing crucibles for the vapor deposition process. Currently, up to a kilogram of an alkalihalide salt is melted electrically in a tantalum crucible within a vacuum chamber, and the vapor is deposited on a metal substrate. The resistance, conductivity, and heating patterns of each crucible — and the vapor cloud it produces — vary from crucible to crucible. The pattern of the cloud changes over time as crucibles age. A thick layer of an inorganic salt — between 400 and 500 micrometers — must be deposited on a metal substrate with microscopic evenness and regularity.
