Graphene from dry ice Researchers at Northern Illinois University (NIU; DeKalb, Ill.; www.niu.edu) discovered a new method for producing graphene that involves burning pure magnesium metal in dry ice. The method, which is capable of producing large quantities of graphene in sheets less than ten atoms thick, is simpler than conventional methods for generating graphene, and avoids hazardous chemicals...

The properties of gold nanoparticles could be combined with those of polydimethylsiloxane (PDMS) to provide a sustainable and practical solution for water treatment, according to a team from the Jawaharlal Nehru Center for Advanced Scientific Research (Bangalore, India; www.jncasr.ac.in). The team, headed by professor Giridhar U. Kulkarni, has synthesized low-density, highly compressible, porous foams of...

A team from CSIRO Materials Science and Engineering (Melbourne, Australia; www.csiro.au) has developed a new technique for growing smart materials known as metal-organic frameworks (MOFs), which can be used in pollution control, or as catalysts, or for transporting drugs in the human body. MOFs are well-ordered ultra-porous crystals that form multi-dimensional structures with huge surface areas. One gram...

A solar cell made of carbon nanotube (CNT) fiber has been demonstrated by researchers from Fudan University (Shanghai; www.fudan.edu.cn). University professor Huisheng Peng says, “For the fibers we use, the carbon nanotubes exhibit a high degree of alignment with much improved mechanical and electrical properties. Therefore those fibers greatly enhance the short current density, open voltage, and the...
