Popular Science | New Technology, Science News, The Future Now At the nuvera fuel cells lab in Cambridge, Massachusetts, 25-year-old chemical engineer Darryl Pollica stands in front of a prototype 5-kilowatt fuel cell -- a miniature powerplant that can make most of the electricity needed by a family of four. Its metal skin has been removed to reveal a cubical frame about 5 feet on each side, packed with tanks, valves, and electronics. Conspicuously taped to the outside of the frame is a Nokia cellphone. "That's our mascot," Pollica says. "We want to shrink this," he says, opening his arms as if to embrace the entire assembly, "to this," and he brings them together and points toward the tiny phone. Pollica's boss, Nuvera Chief Operating Officer Jeff Bentley, a 25-year veteran of the difficult effort to create cost-effective fuel cells that are relatively small, is a bit more cautious. "We're optimists," Pollica shoots back with a confident smile. They better be. Nothing happened. But before we get there, the matter of cost has to be resolved.
No More Thumbprints Researchers have made materials that repel oil and are able to clean themselves without the help of soap and water. What’s more, the researchers describe exactly how the materials work, which could help others design similar materials. This could lead to a range of applications, including fingerprint-shedding cell-phone displays. The researchers, from MIT and the Air Force Research Laboratory at Edwards Air Force Base, in CA, describe their results in the current issue of Science. Making super oil-repellant materials has been one of the great challenges in materials science, says Jeffery Youngblood, a professor of materials engineering at Purdue University, who was not involved in the research. “Before now, superoleophobic materials have been a pipe dream,” Youngblood says. The MIT and Air Force Research Laboratory researchers overcame the obstacles to super oil-repellant materials by combining two advances. But the chemistry of the material isn’t enough to make it super oil repellant.
Lenticular printing Close-up of the surface of a lenticular print. Lenticular printing is a technology in which lenticular lenses (a technology that is also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as the image is viewed from different angles. Examples of lenticular printing include prizes given in some snack boxes that showed flip and animation effects such as winking eyes, and modern advertising graphics that change their message depending on the viewing angle. Process Lenticular printing is a multi-step process consisting of creating a lenticular image from at least two images, and combining it with a lenticular lens. Lenticular printing has been used to produce movie posters, such as this advert for Species II, which morphs between two different character appearances when the angle of viewing changes. Recently, large format (over 2m) lenticular images have been used in bus shelters and movie theaters. Construction

Geekologie - Gadgets, Gizmos, and Awesome Hart wie Diamant – amorph wie Glas - Wissenschaft aktuell Neues Material aus Kohlenstoff hält enormen Drücken von bis zu 1,3 Millionen Atmosphären stand Washington (USA) - Kein anderes Material auf der Erde ist so hart wie Diamant. Doch ein neuer Werkstoff – ebenfalls aus dem Element Kohlenstoff – könnte nun an diesem "Thron der Stabilität" rütteln. Mit speziellen Pressen fertigten amerikanische Physiker nun ein neues Kohlenstoffmaterial, das selbst Druckbelastungen standhielt, die über einer Million größer sind als der Druck der Atmosphäre. Wie sie in der Fachzeitschrift "Physical Review Letters" erläutern, kommt der superharte Kohlenstoff dabei völlig ohne den sonst stabilisierenden kristallinen Aufbau aus. "Diese Entdeckung eröffnet viele Möglichkeiten potenzieller Anwendungen", sagt Russel Hemley vom Geophysical Laboratory der Carnegie Institution for Science in Washington. Detailanalysen zeigten, dass sich die Atome in dieser neuen Form des Kohlenstoffs nicht zu geordneten Kristallen verknüpften.

by @robfitz - Tools and guidance for confused founders In my first company, I tried to act extroverted, because I thought that’s what good leaders did. It was exhausting and counter-productive. I’ve found a more comfortable way of working and wanted to share a few thoughts and resources that have been helpful to me. The back-thumping, rapport-building, steak-and-strippers salesman is just one of several styles, and it’s not even the most effective. In fact, it tends to be actively harmful if you’re developing long-term relationships (like in large sales, long-term partnerships, and fund-raising). The turning point for me was realising that it’s okay not to have all the answers. And finally, not all sales is created equal. I like YC’s attitude on pitching to investors: it doesn’t matter how awkward you are, as long as your startup is good enough. The one point I wanted to make before we get started is, we actually don’t spent a lot of time at YC focusing on this. Having an office is probably my least favourite part of having a company.
