The current technology for catalytic oxidation of aqueous organic contaminants at elevated temperature and pressure works well at operating conditions of 265 °F and 70 psia with effluent TOCs (total organic carbon) of less than 0.5 ppm. However, it does not perform well at the reduced...

NASA’s Kennedy Space Center (KSC) seeks to license its Advanced Fire Retardant Materials to industry. KSC’s scientists have developed processes and know-how to impart fire retardancy to common polymers such as nylons, polyesters, and...

Washington State University researchers have created a multi-functional smart material that changes shape when subjected to heat or light; the material then assembles and disassembles itself.

NASA’s Langley Research Center has developed a method for exfoliating commercially available hexagonal Boron Nitride (hBN) into nanosheets a few atomic layers thick. Currently, hBN has limited use because it is insoluble with limited dispersibility, despite hBN having excellent thermal...

Low-cost access to space demands durable, cost-effective, efficient, and low-weight propulsion systems. Key components include boost and upper stage rocket engine nozzles and extensions. Nozzle material options include ablatives,...

Advanced composite materials processable by cost-effective manufacturing play an important role in developing lightweight structures for future space and planetary exploration missions. With the growing demand for improved performance in the...

A unique binder was developed that exhibits a glass transition temperature of –100 °C, which is more than 50 °C lower than that of traditional HTPB (hydroxyl-terminated polybutadiene) and CTPB (carboxyl-terminated polybutadiene) binders. This innovation would be a solid propellant that would...

A method creates thermally healable composites using carbon nanotubes. Carbon nanotube microwave heating provides a pathway to overcome issues associated with electrical resistive heating networks. Carbon nanotubes embedded within a thermally reversible polymer can be...

The Toughened Uni-piece Fibrous Reinforced Oxidation-Resistant Com posite (TUFROC) allows for much more affordable and sustainable operations involving Space Launch Services and other systems that utilize Earth reentry vehicles. TUFROC has an exposed surface design and...

Reducing the cost and weight of launch structures is essential to meeting NASA goals for reliable access to space. Currently, separate systems are used for structure and pressure containment, cryogenic insulation, and high-temperature insulation. One way...

Engineers at the Massachusetts Institute of Technology (MIT) have developed a way to prevent hydrogels from dehydrating. The water-based technique could lead to longer-lasting contact lenses, stretchy microfluidic devices, flexible bioelectronics, and even artificial skin.

By combining biology and 3D printing, Lawrence Livermore National Laboratory (LLNL) scientists have created a reactor that continuously produces methanol from methane at room temperature and pressure.

In conventional 3D printing, a nozzle scans across a stage: depositing drops of plastic, rising slightly after each pass, and building an object in a series of layers. A new "on-the-fly" prototyping system from Cornell University allows the designer to make refinements while printing is in...

Use of arrays of carbon nanotubes (CNTs) as an intermediary for transport of electrical particles (e.g., electrons) and/or transport of thermal energy from one body to another has grown. For example, a CNT array may be used for dissipation of thermal energy or accumulated electrical...

This work focused on enhancing catalyst activity and durability by developing a method to control size, dispersion, and exposure. Existing nanocatalysts are typically fabricated in bulk or powder form. There are monolithic catalysts, but they rely on meso-porous materials as supports. Bulk nanocatalysts suffer...
