Big Steps Toward Controlled Structure of Nanomaterial Production 

From  Princeton Plasma Physics Laboratory, March 8, 2018, by John Greenwald:
 
"Scientists from U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed the diagnostic tools that are being used to advance an improved and integrated understanding of plasma-based synthesis - a widely used but poorly understood tool for creating nanostructures. PPPL scientists and collaborators outline, in several published papers, recent research that could help to develop controllable and selective fabrication of nanomaterials with prescribed structures. Researchers report unique observations of the synthesis in carbon plasma generated by an electric arc in situ, or as the process unfolds.  Three papers break new ground in unraveling the poorly understood arc synthesis process."   READ FULL ARTICLE.

Superalloy Surface Treatment for Improved Performance of Power Turbines


From Tech Briefs, February 1, 2018, by National Energy Technology Laboratory:

"To produce power more efficiently and cleanly, the next generation of power turbines will have to operate at extreme temperatures and pressures. While the use of protective thermal barrier and bond coatings on turbine blades has resulted in significant improvements in superalloy performance including thermal, oxidative, and mechanical protection, these coatings still allow for oxygen diffusion and subsequent reaction with the underlying substrate. A surface treatment process was developed in which reactive metal elements are applied directly to the alloy substrate prior to bond-coating, resulting in reduced oxidation. Further, the process significantly increases corrosive resistance of nickel-based superalloys." READ FULL ARTICLE.

Researchers Create First-Ever Light-Emitting Nanoantennas

From  ITMO University (Russia), February 12, 2018 :

" Young scientists from ITMO University have developed a new type of nanoscale light source based on halide perovskites. The nanosources are subwavelength nanoparticles which serve both as emitters and nanoantennas capable of amplifying light emission inherently without need for additional devices. Moreover, perovskites enable tuning of emission spectrum throughout a visible range by varying the composition of the material. This makes the new nanoparticles a promising platform for creating compact optoelectronic devices such as optical chips, light-emitting diodes, or sensors. They synthesized perovskite films and then transferred material particles from the film surface to another substrate using pulsed laser ablation . " READ FULL ARTICLE.
 

Flat-packed Optical Components

From  A*STAR Research (Singapore), February 22, 2018:

" Surfaces that efficiently redirect the propagation of light have been developed by A*STAR researchers. Reseachers at A*STAR Data Storage Institute and Nanyang Technological University have invented compact and light-weight optical components that could be integrated into portable optoelectronic devices. The team achieves efficient optical channeling at any desired angle using a metasurface comprising an array of asymmetric nanoantennas. Researchers demonstrated this concept experimentally by etching their nanoantenna array design into a thin film of titanium dioxide on a glass substrate. With this novel approach they were able to bend more than 50 per cent of the energy of an incoming beam of green light at an angle of up to 73 degrees. READ FULL ARTICLE.

Remembering Really Fast

From U.S. Department of Energy, Office of Science, February 16, 2018:

" Using terahertz pulses, s cientists at the Center for Integrated Nanotechnologies (Los Alamos National Laboratory) and the United Kingdom have discovered colossal changes in electricity's flow at the desired frequencies and temperature. Researchers found a colossal magnetoresistance at terahertz frequencies at room temperature in high-quality functional nanocomposites. The terahertz conductivity of nanocomposites can be controlled by both an applied magnetic field and temperature. These findings demonstrated a new approach of utilizing optic pulses at terahertz frequencies to probe magnetoresistance, which can revolutionize the design of future memory devices.

Copper Evaporation During Low Pressure Carburizing

From HTPro , February/March 2018, by Trevor Jones et al. (Solar Atmospheres, Inc.) :
 
" Low pressure carburizing (LPC) in a vacuum furnace is increasingly the preferred method for case hardening aerospace gears, with some alloys like Ferrium C61 and C64 designed specifically for LPC. Stringent pressure control and gas species type both play an important role in minimizing the evaporation rate of not only copper, but other elements susceptible to evaporation in vacuum systems. Nitrogen at 2.5 Torr is the most economic and effective gas for minimizing copper evaporation. "    READ FULL ARTICLE.

Toyota Develops New Magnet for Electric Motors Aiming to Reduce Use of Critical Rare-Earth Element

From  Toyota (Japan), February 20, 2018:
 
" Toyota Motor Corporation (Toyota) announces that it has developed the world's first neodymium-reduced, heat-resistant magnet. Neodymium magnets are used in various types of motors such as the high-output motors found in electrified vehicles, use of which is expected to increase rapidly in the future. The new magnet uses significantly less neodymium, a rare-earth element ("rare earth"), and can be used in high-temperature conditions. The newly developed magnet uses no terbium (Tb) or dysprosium (Dy), which are rare earths that are also categorized as critical materials necessary for highly heat-resistant neodymium magnets. A portion of the neodymium has been replaced with lanthanum (La) and cerium (Ce), which are low-cost rare earths, reducing the amount of neodymium used in the magnet.   READ FULL ARTICLE.
