A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometer range (nanoscale). They are one of the allotropes of carbon.
Nanotechnology was defined by the National Nanotechnology Initiative as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). This definition is inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. An earlier description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology.
Nanosensors are nanoscale devices that measure physical quantities and convert these to signals that can be detected and analyzed. There are several ways proposed today to make nanosensors; these include top-down lithography, bottom-up assembly, and molecular self-assembly. There are different types of nanosensors in the market and in development for various applications, most notably in defense, environmental, and healthcare industries. These sensors share the same basic workflow: a selective binding of an analyte, signal generation from the interaction of the nanosensor with the bio-element, and processing of the signal into useful metrics.
Nanomaterials describe, in principle, materials of which a single unit is sized between 1 and 100 nm.
A survey vessel is any type of ship or boat that is used for underwater surveys, usually to collect data for mapping or planning underwater construction or mineral extraction. It is a type of research vessel, and may be designed for the purpose, modified for the purpose or temporarily put into the service as a vessel of opportunity, and may be crewed, remotely operated, or autonomous. The size and equipment vary to suit the task and availability.
AeroVironment, Inc. is an American defense contractor headquartered in Arlington, Virginia, that designs and manufactures unmanned aerial vehicles (UAVs). Paul B. MacCready Jr., a designer of human-powered aircraft, founded the company in 1971. The company is best known for its lightweight human-powered and solar-powered vehicles. The company is the US military's top supplier of small drones —notably the Raven, Switchblade, Wasp and Puma models.
USS Independence (LCS-2) is the lead ship of the Independence-class of littoral combat ships. She is the sixth ship of the United States Navy to be named for the concept of independence. The design was produced by the General Dynamics consortium for the Navy's LCS program, and competes with the Lockheed Martin designed Freedom variant.
The M80 Stiletto is an American prototype naval ship using advanced stealth technologies. The M80 was designed by the M Ship Company then built by Knight and Carver, as an experimental testbed ship for The Pentagon’s Office of Force Transformation. It is notable for its innovative pentamaran hull design and advanced carbon fiber composite construction.
An unmanned surface vehicle, unmanned surface vessel or uncrewed surface vessel (USV), colloqually called a drone boat, drone ship or sea drone, is a boat or ship that operates on the surface of the water without a crew. USVs operate with various levels of autonomy, from remote control to fully autonomous surface vehicles (ASV).
As the world's energy demand continues to grow, the development of more efficient and sustainable technologies for generating and storing energy is becoming increasingly important. According to Dr. Wade Adams from Rice University, energy will be the most pressing problem facing humanity in the next 50 years and nanotechnology has potential to solve this issue. Nanotechnology, a relatively new field of science and engineering, has shown promise to have a significant impact on the energy industry. Nanotechnology is defined as any technology that contains particles with one dimension under 100 nanometers in length. For scale, a single virus particle is about 100 nanometers wide.
Green nanotechnology refers to the use of nanotechnology to enhance the environmental sustainability of processes producing negative externalities. It also refers to the use of the products of nanotechnology to enhance sustainability. It includes making green nano-products and using nano-products in support of sustainability.
Coastal Motor Boat was a small high-speed British torpedo boat used by the Royal Navy in the First World War and up to end of the Second World War.
Zyvex Technologies is a molecular engineering company headquartered in Columbus, Ohio. Zyvex Technologies focuses on developing advanced materials, including prepreg, epoxy resins, and adhesives.
The Piranha Unmanned Surface Vessel is a watercraft developed by Zyvex Marine in 2010. The boat is 54 feet in length and weighs just 8,000 lbs. The Piranha is the first USV to utilize a lightweight carbon-nanotube enhanced composite material called Arovex, which allows the watercraft to weigh "significantly less" than any other USV.
The ASW Continuous Trail Unmanned Vessel (ACTUV) is a DARPA funded project launched in early 2010 to develop an anti-submarine drone. ASW is an acronym for Anti-Submarine Warfare. In January 2018 after successful sea trials it was announced that the "Sea Hunter" prototype has transitioned from DARPA to the Office of Naval Research for further development.
Zyvex is a molecular nanotechnology company, founded by James R. Von Ehr II in 1997.
Juliet Marine Systems Ghost is an advanced super-cavitating stealth ship that can reduce hull friction to 1/900th that of conventional watercraft. It was developed to provide superior protection and capabilities for United States military personnel. It was designed, developed, and built by the private American company Juliet Marine Systems.
North Sea Boats is an international boat-building company specialized in building craft for military, law enforcement, SAR, commercial, and high-performance applications. The company has a presence in Sweden, Singapore, and Indonesia, with its headquarters located at Banyuwangi, East Java, Indonesia. North Sea Boats was founded in 2003 by John and Lizza Lundin as a trading name for PT Lundin Industry Invest.
ULAQ is the prototype of the first Turkish armed unmanned surface vessel (AUSV).
The JARI USV is an uncrewed surface vehicle developed by the China Shipbuilding Industry Corporation (CSIC), specifically between its No. 716 Research Institute, the Jiangsu Automation Research Institute (JARI), and No. 702 Research Institute, China Ship Scientific Research Centre (CSRRC). The uncrewed warship is designed for potential use for the People's Liberation Army Navy and export customers.
