Three-dimensional nanonetworks for giant stretchability in dielectrics and conductors

The realization of levels of stretchability that extend beyond intrinsic limits of bulk materials is of great importance to stretchable electronics. Here we report large-area, three-dimensional nano-architectures that achieve this outcome in materials that offer both insulating and conductive properties. For the elastomer poly(dimethylsiloxane), such geometries enhance the stretchability and fracture strain by ~62% and ~225% over the bulk, unstructured case. The underlying physics involves local rotations of narrow structural elements in the three-dimensional network, as identified by mechanical modelling. To demonstrate the applications of three-dimensional poly(dimethylsiloxane), we create a stretchable conductor obtained by filling the interstitial regions with liquid metal. This stretchable composite shows extremely high electrical conductivity (~24,100 S cm−1) even at strains >200%, with good cyclic properties and with current-carrying capacities that are sufficient for interconnects in light-emitting diode systems. Collectively, these concepts provide new design opportunities for stretchable electronics.

Julian Assange v Rupert Murdoch

Juice Rap News: Episode XIII - A NEWS HOPE. Is an honest Media the one and only Force than can restore peace and balance to the Galaxy? To find out, we consult two of journalism's most influential and inflammatory figures: Rebel journalist, enfant terrible, Julian Assange, who awaits a verdict in London which could see him 'Sextradited' to Sweden. And, on the opposite end of the journalistic spectrum, Rupert Murdoch, head of the mighty NewsCorp media Empire, embroiled in legal scandals that go to the highest and lowest levels of celebrity in Britain. In the manichean manner of some ancient laser sword and forcery epic, join the most retro news-anchor in the Galaxy, Robert Foster, as he attempts to wrangle these two figures together for a rap-debate. Will the light or the dark side prevail - and is it really that easy to know which is which? How many Bothans died to bring us this information? Is the Force Estate with Robert? Will we see THE RETURN OF THE JOURNALI before the EMPIRE EXTRADITES BACK? For answers to all these questions and more, pull down your blast shields, switch off your on-board computer and feel the Force in this latest episode of Juice Rap News... or click play.

Stiglitz says 'Send Bankers to Jail' Without threat of prosecution, says Nobel economist, expect little to change

There’s some interesting stuff in there. Stiglitz says that the Vickers reforms to ringfence retail banking pobably don’t go far enough. He proposes a theory on why Germany practices left-wing economics at home but right-wing economics abroad (there’s a solidarity gulf). He also explains why China can combine high growth with high inequality. Have a look at his answer, too, to the question of how high marginal tax rates should be to curb inequality and discourage rent seeking. 70%?

TV Dinner Gumballs

Remember when there were only three networks and you had to get up out of your chair to change the channel? This is the gum for you! Your vegetable is buttered corn flavored gum, your main dish is roast beef flavored gum and for dessert, apple cobbler flavored gum. Each 3-1/4" x 2-1/2" x 3/4" tin contains about twenty-two, 1.4 oz of nostalgia-inducing gumballs.
