For the first time, the NIST researchers have measured the transfer of motion through the contacting parts of a microelectromechanical system at nanometer and microradian scales.
Scientists at The Australian National University (ANU) have developed a new spray-on material with a remarkable ability to repel water. The new protective coating could eventually be used to waterproof mobile phones, prevent ice from forming on airplanes or protect boat hulls from corroding.
The growth of bacterial biofilm is problematic when you think of all the liquid flowing through all those miles of tubing at your local hospital or Medi-Centre. The movement of bacteria with flow can lead to the spread of infection. Mechanical engineering professor Aloke Kumar's lab set out to study the formation of the filaments, as well as the conditions under which they begin to break down and finally break off.
How metals can be used depends particularly on the characteristics of their surfaces. A research team at Kiel University has discovered how they can change the surface properties without affecting the mechanical stability of the metals or changing the metal characteristics themselves. This fundamentally new method is based on using an electrochemical etching process, in which the uppermost layer of a metal is roughened on a micrometer scale in a tightly controlled manner.
'Promising' and 'remarkable' are two words US Department of Energy's Ames Laboratory scientist Javier Vela uses to describe recent research results on organolead mixed-halide perovskites.
With one in two Australian children reported to have tooth decay in their permanent teeth by age 12, researchers from the University of Sydney believe they have identified some nanoscale elements that govern the behavior of our teeth. Material and structures engineers worked with dentists and bioengineers to map the exact composition and structure of tooth enamel at the atomic scale.
University of Manchester researchers have discovered how to create the smallest ever water and gas pipes that are only one atom in size.
Scientists at the Energy Department's National Renewable Energy Laboratory (NREL) discovered a use for perovskites that runs counter to the intended usage of the hybrid organic-inorganic material.
Superatom crystals are periodic arrangements of C60 fullerenes and similarly sized inorganic molecular clusters. There are two nearly identical formations, one with rotating (i.e. orientationally disordered) C60s and low conductivity, and one with fixed C60s and high thermal conductivity. Superatom crystals represent a new class of materials with potential for applications in sustainable energy generation, energy storage, and nanoelectronics. Additional research could lead to controlling rotational disorder in new kinds of thermal switches and transistors.
Rice University researchers turn nanotubes into nanodiamonds and other forms of carbon by smashing them into a target at hypervelocity. The results will help in the design of light, strong materials for aerospace applications.
