With fuzzy nanoparticles, researchers reveal a way to design tougher ballistic materials
Researchers have discovered a new method to improve the toughness of materials that could lead to stronger versions of body armor, bulletproof glass and other ballistic equipment. The team produced films composed of nanometer-scale ceramic particles decorated with polymer strands (resembling fuzzy orbs) and made them targets in miniature impact tests that showed off the material's enhanced toughness. Further tests unveiled a unique property not shared by typical polymer-based materials that allowed the films to dissipate energy from impacts rapidly.

Development of a high-energy-resolution, LaB6 nanowire-based field emission gun
Engineers have developed a lanthanum hexaboride (LaB6) nanowire-based field emission gun that is installable on an aberration-corrected transmission electron microscope (TEM). This combined unit is able to perform atomic resolution observation at an energy resolution of 0.2 eV -- the highest resolution ever recorded for non-monochromatic electron guns -- with a high current stability of 0.4%.
