IS THE FUTURE HAPPENING RIGHT NOW, AND WE'RE NOT EVEN AWARE OF IT?
GRAPHENE 0.5 K
GRAPHENE SHEET
GRAPHENE SUPERLATIVES
THINNEST MATERIAL IMAGINABLE LARGEST SURFACE AREA (2700 M2/GR) STRONGEST MATERIAL EVER MEASURED: 42 NM–1 (5XSTEEL.. AND MUCH LIGHTER) STIFFEST MATERIAL KNOWN (≥ DIAMOND) MOST STRETCHABLE CRISTAL (20%)
MOST IMPERMEABLE RECORD THERMAL CONDUCTIVITY HIGHEST CURRENT DENSITY AT 300 K (106 TIMES CU, 109 A/CM2) LONGEST MEAN FREE PATH AT 300 K (µM) HIGHEST INTRINSIC MOBILITY (102 X SI) LIGHTEST CHARGE CARRIERS (ZERO EFFECTIVE MASS)
NEW CONDUCTIVE COMPOSITES FOR AERONAUTICS: LIGHTING PROTECTION, PLANETARY REENTRY
