Making buckypaper The Masdar Institute of Science and Technology has developed a process that will transform carbon nanotube powder into so-called buckypaper. Buckypaper is a thin sheet made from carbon nanotubes. They are sometimes known as multi-walled carbon nanotube sheets. Meanwhile, carbon nanotubes are tube-shaped materials, which are 100,000 times smaller than the diameter of human ... » read more

Ion implant lithography At a recent conference, the University of California at Berkeley presented more details about its efforts to develop a multiple patterning method using tilted ion implantation (TII) technology. TII is somewhat similar today’s self-aligned double patterning (SADP) processes in logic and memory. SADP and the follow-on technology, self-aligned quadruple (SAQP), enable... » read more

Brain microscopes Rice University is developing a tiny and flat microscope for a special application--it will be able to decode and trigger neurons on the surface of the brain. The microscope technology, dubbed FlatScope, is part of a $65 million program announced by the U.S.-based Defense Advanced Research Projects Agency (DARPA). The DARPA project, dubbed Neural Engineering System Design ... » read more

Solar cell metrology Using atomic force microscopy (AFM), the National Institute of Standards and Technology (NIST) has developed a pair of novel techniques to measure the chemical compositions and defects in solar cells. The new techniques will give researchers insights into a thin-film solar cell material called cadmium telluride. The technology will also suggest ways to boost the efficie... » read more

Pushing optical metrology The University of Illinois at Urbana-Champaign has developed a new way to determine crystal types using optical metrology techniques. Using an optical-based technique called absorption spectroscopy, researchers have detected tiny nanocrystals down to about 2nm resolutions. Absorption spectroscopy measures the absorption of radiation. It is measured as a function o... » read more

‘Big G’ gravitation measurements The National Institute of Standards and Technology (NIST) has unveiled a new coordinate measuring machine (CMM). The CMM, dubbed Xenos, makes measurements that involve “big G” or the universal constant of gravitation. Basically, there are two meanings for the constant of gravity. The first is Newton’s universal law of gravitation. For this, the spe... » read more

AFM-on-a-chip An atomic force microscope (AFM) is a metrology tool that can measure and characterize structures in three dimensions. It uses a tiny probe to enable measurements in chip structures, but the instrument itself is often a large and bulky system. In response, the University of Texas at Dallas has devised an AFM-on-a-chip technology. The AFM is roughly the size of a dime. Based on... » read more

Coffee ring effect In physics, the “coffee ring effect" has been the subject of study for years. This phenomenon is a simple concept. A liquid or droplet hits a surface and dries. The particles in the droplet are suspended. And ultimately, it leaves a ring-like pattern. The phenomenon is named for the formation of a ring-like deposit when coffee or other liquid resides on a surface. ... » read more

Measuring gooey materials The National Institute of Standards and Technology (NIST) and Thermo Fisher Scientific have devised an instrument that correlates the flow properties of “soft gooey” materials, such as gels, molten polymers and biological fluids. The instrument, called a rheo-Raman microscope, combines three instruments into one system. First, the system incorporates a Raman sp... » read more

Crystal database The University of California at San Diego and Lawrence Berkeley National Laboratory have created an open-source database of elemental crystal surfaces and shapes. The database, called Crystalium, is a new and expanding set of information about various crystals. The database can help researchers design new materials for various applications, such as batteries, catalytic conv... » read more
