Scientists at the University of Vienna have created a new hybrid structure, termed buckyball sandwich, by encapsulating a single layer of fullerene molecules between two graphene sheets. Buckyball sandwiches combine for the first time soccerball-like fullerenes, each consisting of sixty carbon atoms, and graphene, a one-atom thick layer of carbon.

Femtosecond laser electronic excitation tagging (FLEET) is an optical measurement technique that permits quantitative velocimetry of unseeded air or nitrogen using a single laser and a single camera. This paper seeks to determine the fundamental precision of the FLEET technique using high-speed complementary metal-oxide semiconductor (CMOS) cameras. A comparison of the performance of several different high-speed CMOS camera systems for acquiring FLEET velocimetry data in air and nitrogen free-jet flows is also provided.
This paper provides an overview of recent wind tunnel tests performed at the NASA Langley Research Center where the Background-Oriented Schlieren (BOS) technique was used to provide information pertaining to flow-field density disturbances. The facilities where the BOS technique was applied included the National Transonic Facility (NTF), Transonic Dynamics Tunnel (TDT), 31-Inch Mach 10 Air Tunnel, 15-Inch Mach 6 High-Temperature Air Tunnel, Rotor Test Cell at the 14×22 Subsonic Tunnel, and a 13-Inch Low-Speed Tunnel.
One of the key parameters for understanding how a laser will perform in an application is the spatial intensity distribution. In many industial laser cutting or welding applications, monitoring the beam quality is critical for successful operation. The measurement of the beam can either be made during the design stage of the laser, or it might be more sufficient for continuous real-time monitoring during the laser’s operation. This white paper addresses the general need for laser beam profile analysis, describes laser beam analysis instruments, and provides an overview of laser applications, in particular for infrared wavelengths.
