Adaptive Ecosystem Climatology

Naval Research Laboratory

The Adaptive Ecosystem Climatology (AEC) is a system for rapidly merging oceanographic observations with numerical simulations to provide an online decision-support tool (with analysis and visualization capabilities) for ecological forecasting. The Naval Research Laboratory detachment at Stennis Space Center has developed the AEC to provide a flexible tool for eco-forecasting applications. The AEC melds observations collected by oceanographers, amateur observers, e.g., boaters, fishermen, beachgoers, students, crowdsourcing, Earth Observation (EO) satellites, archived in situ data, and output from a state-of-the-art, data assimilative, coupled bio-optical-physical ocean model system. The AEC mitigates the shortcomings of the components and combines their strengths to enhance decision-making activities for end-user organizations. Using the visualization and analysis tools available on the AEC portal, the satellite and model climatologies can be displayed and manipulated, and the data files can be downloaded by users, for direct input into external management models, such as ecosystem, oil trajectory, or fisheries models.

Adjustable Depth Air Sparging

Naval Facilities Engineering and Expeditionary Warfare Center

Naval Facilities Engineering and Expeditionary Warfare Center has developed the adjustable depth air sparging (ADAS) system that allows the user to precisely and repeatedly adjust the depth of air injection without the expense of having to install new air sparge wells. The ADAS system employs an inflatable flow-through packer, a device that slides annularly through the same type of directly driven well as used for conventional air sparge systems. The flow-through packer is designed to seal off the interior of the air sparge well so that injection air flowing out from the bottom of the packer does not travel back up the interior of the well. The system allows an operator to manually raise and lower the packer without the need for specialized equipment.

Enhanced Solar Cells

Naval Air Warfare Center Weapons Division, China Lake

Researchers at Naval Air Warfare Center Weapons Division, China Lake (NAWCWD) developed an evolutionary new technology for increasing the efficiency and durability of solar cells. New portable power for warfighters could include extending the range of electric powered drones or power for distributed sensors (security cameras), etc. Trapping each color of the rainbow within nanoplasmonic cavities has proven useful. NAWCWD synthesized light-harvesting materials and used a layer-by-layer deposition technique (APD) that enabled precise (within a few nanometers) control over the film thickness, gradient, and precise positioning. Titania, polymer photoabsorbers, and carbon nanotube electrodes further enhanced trapping and light absorbance. A power systems core science and technology project produced the first designs of nanoplasmonic cavities filled with APD polymer photoabsorbers. The cavity resonances were optimally tuned to the color absorbed thus increasing the efficiency of the solar cell. Using materials designed for maximum compatibility, multi-layer nanostructures were fabricated allowing rapid scale-up for mass production of large area devices. NAWCWD’s advanced computer modeling led to optimum device designs. Department of Defense applications could benefit unmanned systems by increasing loiter time to assist Intelligence, Surveillance, and Reconnaissance/Target Acquisition (ISR/TA) missions. The technology benefits the Department of Defense and any other organization photovoltaic batteries for any application.

Flush Rinse Tank

Naval Surfare Warfare Center, Indian Head Explosive Ordnance Disposal Technology Division

Usually various electroplated metals or metal alloys protect equipment parts from corrosion.
Parts are usually prepared by cleaning, rinsing, plating, rinsing, electroplating, rinsing,
etc. Naval Surface Warfare Center, Indian Head Explosive Ordnance Disposal Technology
Division has patented a system that supplies fresh water for each rinse operation. A flushing
tank and diverter valve separates rinse water waste into different streams for further
processing, reclamation, or reuse. This system replaces other large or multiple rinse tanks
with one centrally located flush rinse tank. This system should help commercial platers
better meet Environmental Protection Agency water discharge regulations by preventing
precipitates that may form by combining waste streams. Moreover, the flush rinse tank
should have a smaller footprint than the multiple rinse tanks normally used.

High Density Renewable Fuels

Naval Air Warfare Center Weapons Division, China Lake

Naval Air Warfare Center Weapons Division, China Lake has developed a variety of renewable high density fuels that have applications for jet, diesel, missile, and unmanned aerial vehicle propulsion. These fuels can be produced in a sustainable fashion from waste biomass and have been designed to outperform both conventional renewable fuels as well as petroleum derived fuels. Potential commercial application areas include: jet/diesel fuel; high octane gasoline; motor oil; lubricants; resins; paint; coatings/finishes; scents/flavorings; and cosmetics.

High Performance Trivalent Chromium Pre-Treatment (TCP)

Naval Air Warfare Center Aircraft Division

Naval Air Warfare Center Aircraft Division has developed and filed a patent application on a new TCP composition and process that enables 50 percent greater salt fog resistance and broader applications with greater consistency—including 2xxx series alloys for aerospace applications under MIL-DTL-81706—as compared to the Navy’s original TCP. The technology has been demonstrated at the 2-liter scale for unpainted (bare) corrosion resistance. Paint adhesion and painted corrosion testing are planned with the ability to scale up to larger volumes, likely 10 gallons. Further field testing, scale-up, and optimization work are needed for commercial use. In addition to coating bulk metals, high-performance TCP also holds promise for coating aluminum powders that are used in corrosion-resistant paints and primers, such as the Navy’s aluminum-rich primers. In this application, high-performance TCP may offer economic advantages by reducing processing costs and decreasing the volume of TCP in waste streams, as compared to current products and practices. The application of high-performance TCP on metallic powder is in the proof-of-concept phase.

High Value Silicon Carbide from Agricultural Waste

Naval Research Laboratory

Research scientists at the Naval Research Laboratory have shown that using high temperatures
or microwaves many agricultural wastes can be transformed into high value silicon
carbide (SiC) consisting of nanostructures and nanorods in various polytypes. Billions of
pounds of agricultural waste are generated every year worldwide. Rice and wheat husks,
corn stalks, cobs, sorghum leaves, peanut shells and other residues are considered to have
no value and are plowed into fields or incinerated. Normal incineration temperatures create
environmental problems by releasing ash, carbon dioxide, and nanoparticles into the
air. However, these agricultural wastes have significantly high silica content in a molecular
state in close proximity to hydrocarbons. Silicon carbide is used for electronic and structural
devices due to its high breakdown voltage, chemical inertness, high thermal conductivity,
dimensional stability, wide band gap, high radiation resistance, thermal shock resistance,
and mechanical hardness. Scientists are engaged in transforming these silicon carbide
nanomaterials into transparent windows and domes for applications as armor, hypersonic
missiles, and thermal control of thin disc lases. Potential uses of SiC for chemical
sensing, optical metamaterials, structural composites and nanoscale electronic devices are
also being investigated at NRL as well as applications which promise enhancements in infrared

Low Energy Desalination System

Naval Surface Warfare Center, Corona Division

Naval Surface Warfare Center, Corona Division seeks partners to license and commercialize a water purification system utilizing naturally occurring ocean temperature gradients. The United Nations expects that 14% of the world’s population will encounter water scarcity by 2025. Purifying ocean water into drinking water has not been economically viable for multiple reasons—one major reason is the enormous quantities of energy required to boil and condense water. This novel invention by Navy researchers utilizes naturally occurring thermal gradients in the ocean to transfer needed energy to and from the water. The ocean is used as the heat source and heat sink for evaporating non-potable (saline) water. This saves the significant cost of having to input all the necessary energy from manmade sources. In addition, the application is not limited to saltwater, can be configured on a derrick or ocean platform, and can be partially submerged in the event of rough seas.


Naval Air Warfare Center Aircraft Division

Growth of mildew on military aircraft frames has been found to cause corrosion and operational damage, in addition to creating potential health hazards to flight crews and maintenance personnel. NAVCLEAN dry is a dry mildew remover kit that improves the efficacy, portability and shelf stability of the original NAVCLEAN, and also reduces disposal problems associated with hazardous wastes. NAVCLEAN dry will be packaged as a kit. All of the ingredients in the kit are made of stable, solid materials (powder and/or granules), are soluble in water and are commercially available. After mixing with water, NAVCLEAN dry must be used within 24 hours after which the efficacy declines until 96 hours when it becomes inert. NAVCLEAN dry has been tested on a number of surfaces including aluminum alloys, steel, painted surfaces, plastic, and polyimide wire insulation, and is expected to perform equally well on other corrosion-sensitive surfaces. In addition to United States military markets, commercial applications may include: architectural restoration, industrial equipment remediation and treatment of HVAC systems, among many others. NAVCLEAN dry has been developed with Environmental Protection Agency (EPA) mildewcide standards of 99 percent effectiveness in mind, and the Navy is pursuing EPA registration of NAVCLEAN dry as a mildewcide.

Oily Sludge BioReactor

Naval Facilities Engineering and Expeditionary Warfare Center

Department of Defense facilities generate thousands of tons of oily sludge annually at industrial wastewater treatment plants, wash racks, fuel depots, industrial operations, and maintenance facilities. This waste cannot be recycled or burned and must be drummed for disposal at landfills or stored in expensive, specially-lined sludge pits. Private industry also creates oily sludge from refining operations and other industrial efforts. This patented technology represents a method of using a bioreactor built as a permanent installation to receive sludge from delivery trucks or a pipeline. A 9k gallon reactor system can handle 3k to 4k gallons of raw sludge per month or 15k to 20k gallons of diluted sludge. A reaction cycle takes three to five days, and results in clean effluent that can be discharged in the sewer or can be used as make-up water for incoming sludge. Three systems have been built and practiced with excellent results.

PEEK™-Like Phthalonitriles: Base Resin Manufacturing

Naval Research Laboratory

The Naval Research Laboratory has developed a new class of PEEK™-like phthalonitrile (PN) resins, when in the melt-state, are easily processed and cured, and produce high temperature thermosets. The PN base resins are synthesized in a two-step, one-pot reaction in quantitative yields and require no further purification (n < 1). A simple workup, along with utilizing cost effective starting materials, make manufacturing these new PN resins competitive to other thermoset base resins. The resin formulations are indefinitely stable under ambient conditions and can be prepared either as a powder or to a specified viscosity (and gel time) for use in existing commercial resin processes. An example of such phthalonitrile-based products are polymer matrix composites (PMC) which exhibit high thermal and oxidative stability approaching 500 °C (930 °F) in air, have low water absorption, retain structural integrity in a fire environment, and show thermal properties that exceed Navy expectations for composite ship and aircraft applications.

PEEK™-Like Phthalonitriles: Melt-Processable, High Temperature Polymers

Naval Research Laboratory

The Naval Research Laboratory has developed a new class of PEEK™-like phthalonitrile
(PN) resins for use in a variety of applications due to their ease of processability when in a
melt-state followed by curing to produce high-temperature, high-char polymeric thermosets.
The PN resins, where n < 1, were initially designed to fabricate polymer matrix composites
(PMC) by cost effective manufacturing methods such as resin transfer molding, a type of out of autoclave processing. The resin formulations are indefinitely stable under ambient conditions and can be prepared to various viscosities and gel times for use in all commercial resin processes. Phthalonitrile-based PMCs exhibit high thermal and oxidative stability approaching 500 °C (930 °F) in air, have low water absorption, retain structural integrity in a fire environment, and show thermal properties that exceed Navy expectations for composite ship and aircraft applications.

Perchlorate-Free Flares

Naval Surface Warfare Center, Crane Division

Pyrotechnics are used in a variety of applications including fireworks and colored signal flares. Currently available fireworks and signal flares use perchlorate oxidizers to produce their desired colors. Residual perchlorates from pyrotechnic devices may leach into groundwater and cause widespread contamination that requires remediation. Naval Surface Warfare Center, Crane Division has reformulated pyrotechnic compositions for red, yellow, and green to remove perchlorate ingredients, while maintaining or improving performance. Compositions have been developed, prototyped, and tested with documented results.

Remote Environmental and Condition Monitoring System

Naval Surface Warfare Center, Port Hueneme Division

The present disclosure relates to systems and processes for environmental and condition monitoring of containerized assets. One illustrative system includes containers that are configured to enclose assets that are potentially hazardous and/or potentially sensitive to electromagnetic/radio frequency radiation or emissions. The assets may also be sensitive to various environmental conditions such as temperature, humidity, shock and vibration. An exemplary system uses sensors to measure and track these environmental conditions inside a container for multiple years. An illustrative system may also use sensors to measure attributes of the asset, be configured to archive and report on the collected data, and include the ability to issue a warning when an asset may have been compromised. The collected data may be used in predictive life analyses. More particularly, the collected data may be analyzed and compared to thresholds for container assets to reach deductive or inductive conclusions about the probability of damage, maintenance needs, or replacement needs.
