Researchers Craft New Material That Could Improve LED Screens

Researchers working at the Ultrafast Laser Lab at the University of Kansas successfully created a new bilayer material, with each layer measuring less than one nanometer in thickness. The new material, that someday could lead to more efficient and versatile light emission, was made by combining atomically thin layers of molybdenum disulfide and rhenium disulfide.

Researchers Find 'Golden' Idea for New Wearables

Researchers at Missouri University of Science and Technology have developed a way to “grow” thin layers of gold on single crystal wafers of silicon, remove the gold foils, and use them as substrates on which to grow other electronic materials. The discovery could lead to new wearable developments, including a smartphone that conforms entirely to one's wrist.

The Ultimate Tool for Characterizing Materials during Mechanical Tests and Validating FEA during Component Tests

The Digital Image Correlation Technology (DIC) is a non-contact 3D measurement tool that measures deformation and strain during material testing. DIC is a single system that replaces strain gages, accelerometers, LVDT’s, string potentiometers, extensometers, laser trackers, and surface scanners. The results are full field, and presented as an experimental representation of a finite model.

The Heavy Impact of Advanced Lightweight Materials

Historically, high-strength materials have been heavy and dense. The need for high-strength but lightweight materials has become more widespread when designing everything from vehicles and aircraft, to buildings and wind turbines. These advanced materials are enabling engines to operate efficiently at higher temperatures, use less fuel, and emit fewer pollutants, as well as finding uses in many other applications.

'Tougher-than-Metal' Hydrogels Support New Biomaterials

Scientists from Japan's Hokkaido University have created tough hydrogels combined with woven fiber fabric. The "fiber-reinforced soft composite" fabrics are highly flexible, stronger than metals, and can support a number of potential applications, including artificial ligaments and tendons subjected to load-bearing tension.

Engineers and scientists at the University of Texas at Austin and the AMOLF institute in the Netherlands have invented mechanical metamaterials that transfer motion in one direction while blocking it in the other. The material can be thought of as a mechanical one-way shield that blocks energy from coming in but easily transmits it going out the other side. The researchers developed the mechanical materials using metamaterials, which are synthetic materials with properties that cannot be found in nature.

Light-Absorbent Material Keeps Buildings Cool

Engineers at the University of California San Diego have created a thin, flexible, light-absorbing material that absorbs more than 87 percent of near-infrared light. The technology could someday support the development of solar cells; transparent window coatings to keep cars and buildings cool; and lightweight shields that block thermal detection.

Metallic Glass Shatters Gear Limitations

Gears play an essential role in precision robotics, and they can become a limiting factor when the robots must perform in space missions. In particular, the extreme temperatures of deep space pose numerous problems for successful gear operation. At NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, CA, technologist Douglas Hofmann and his collaborators aim to bypass the limitations of existing steel gears by creating gears from bulk metallic glass (BMG).
