Like a Hot Knife Through Butter ...with a New Twist
My
son-in-law, Matt,
showed me this video demonstrating the incredible thermal conduction
property of graphene. A miracle material for seemingly every other realm
of physics, thermo-conductive pyrolytic graphite (TCPG)
conducts heat with twice the efficiency of diamond, and 6x the efficiency
of copper and silver. Because of the extreme thermal conductivity, the
heat from the guy's fingers is enough to slowly force the graphene sheet
through the ice cube. In the future, the colloquial saying for expressing
how easily a material is cut might change from "like a hot knife through
butter" to "like a body-temperature graphene sheet through an ice cube."
RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a lady's voice announced "You've Got Mail"
when a new message arrived...
