One-molecule-thick material has big advantages: MIT researchers produce complex electronic circuits from molybdenum disulfide, a material that could have many more applications

The discovery of graphene, a material just one atom thick and possessing exceptional strength and other novel properties, started an avalanche of research around its use for everything from electronics to optics to structural materials. But new research suggests that was just the beginning: A whole family of two-dimensional materials may open up even broader possibilities for applications that could change many aspects of modern life.

Novel technique to synthesize nanocrystals that harvest solar energy

One reason that solar energy has not been widely adopted is because light absorbing materials are not durable. Materials that harvest solar radiation for energy often overheat or degrade over time; this reduces their viability to compete with other renewable energy sources like wind or hydroelectric generators.

Zapping Rocks Exposed by the Sky Crane's Thrusters
This photo mosaic shows the scour mark, dubbed Goulburn, left by the thrusters on the sky crane that helped lower NASA's Curiosity rover to the Red Planet. It is located 16 to 20 feet (5 to 6 meters) to the left of the rover's landing position. The sky crane appears to have uncovered an outcrop of loosely consolidated rocks during the rover's landing.

Super-Strong, High-Tech Material Found to be Toxic to Aquatic Animals by Researchers at MU and USGS: Carbon nanotubes hold promise for industry but need monitoring, say researchers

Carbon nanotubes (CNTs) are some of the strongest materials on Earth and are used to strengthen composite materials, such as those used in high-performance tennis rackets. CNTs have potential uses in everything from medicine to electronics to construction. However, CNTs are not without risks. A joint study by the University of Missouri and United States Geological Survey found that they can be toxic to aquatic animals. The researchers urge that care be taken to prevent the release of CNTs into the environment as the materials enter mass production.

Silver Nanoparticles Utilized to Modify Performance of Hydrogen Peroxide Sensor

Iranian researchers at Masjed Soleiman and Gorgan Branches of Islamic Azad University in cooperation with their colleagues from the University of Malaya succeeded in increasing the sensitivity of hydrogen peroxide nanosensor by placing silver nanoparticles on the electro-active nanolayers.
