Crawling Robot is Powered by Moisture

Using an off-the-shelf camera flash, researchers at Jilin University, China, turned an ordinary sheet of graphene oxide into a material that bends when exposed to moisture. They then used this material to make a spider-like crawler and claw robot that move in response to changing humidity, without the need for any external power.

ABLE TECHNICAL GUIDE: Your Solution to 7 Metal Surface Problems

Electropolishing is often referred to as a “reverse plating” process. Electrochemical in nature, electropolishing uses a combination of rectified current and a blended chemical electrolyte bath to remove flaws from the surface of a metal part.

‘Solar Paint’ Produces Energy from Sunlight

A team from Australia’s RMIT University created a “solar paint” that generates its own energy. The sunlight-absorbing substance absorbs and splits water atoms, resulting in hydrogen that could someday be used to power fuel cells and conventional combustion engines.

Adam Sidor, NASA Research Fellow, Georgia Institute of Technology, Atlanta, GA

Thermal Protection Systems (TPS) — heatshields — form the outer surface of spacecraft and provide protection as the vehicle plunges through planetary atmospheres. Conformal ablative materials are currently being developed to improve TPS performance. Adam Sidor is developing a fresh approach to designing and manufacturing these materials to produce larger tile sizes while reducing labor, cost, and waste.

Combination Structural Support and Thermal Protection System

Applications include engine firewalls in general aviation aircraft, turbine engines, automobiles, or other ground vehicles; and in building construction for fire protection.

NASA's Langley Research Center has developed a system that provides both structural support and protection attributes in a failsafe manner. This innovation incorporates the use of a pre-ceramic polymer (PCP) composite structure that when overheated or exposed to fire or plasma will convert to a ceramic matrix composite (CMC), retaining structural integrity and still functioning effectively. When damage causes the thermal protection system (TPS) to fail, the underlying PCP structure converts to a CMC material that has high-temperature structural properties, will not catch fire or melt, and continues to perform its structural function.

Composite Insulated Conductor

These extreme fire-resistant insulation systems show promise for use in high-voltage, high-power systems.

NASA's Langley Research Center has developed a new class of polyimide composite electrical insulation materials for wires, cable, and bus pipe. These new insulation materials have been shown to withstand a 12-hour gas flame test while maintaining structural and electrical circuit integrities. These extreme fire-resistant insulation systems show promise for use in high-voltage, high-power systems. They can improve survivability and continuity of the electrical power supply. Besides fire resistance, these materials also provide weight and space savings because of their lightweight nature and exceptionally high-performance capability. NASA developed the wire insulation for exploration and space operations; however, the technology also has applicability to other high-voltage, high-power systems for maritime, high-rise building construction, and other industries.
