A new paper in Nature describes the US-Army-funded research of U Penn materials scientists to create a new generation of 3D printed "smart objects" whose geometry and materials enable them to interact with their environments without having to use embedded computers, sensors or actuators.

Cajiso's "paper watches" wrap a watertight tyvek wristband with a magnetic closure around a cheap-and-cheerful LED watch mechanism, yielding a $28 novelty/fashion item that can be printed with arbitrary bitmaps and are thus available in a wide variety of patterns. (via Red Ferret)

A team of material scientists from Northwestern University figured out how to make hair dye in various shades of grey, all the way to a very, very black black, out of graphene sheets.

Skycool Systems is a Stanford spin-out that uses panels composed of "layers of silicon dioxide and hafnium oxide on top of a thin layer of silver" to convert the waste-heat from air-conditioners' heat exchangers into 8-13 micrometer radiation, which passes through the atmosphere and radiates into space.

Penn State researchers funded by the Army Research Office and the Office of Naval Research have posted video showing their progress on "self-healing" textiles that use proteins similar to those found in human hair and squid teeth to allow fibers to coated in polyelectrolytes so that they can be set and bonded using safe solvents under ambient conditions.

Dutch design house Nightshop sourced soft urethane nonskid foam, which starts off as a liquid that you squirt out of a syringe, and they proceeded to weave a series of handmade rugs out of it. Read the rest
A new book, Material Innovation: Packaging Design, written by a material science consultant and a design consultant, explores the ways that packaging is being changed by innovations in retail, materials, design, and marketing. Read the rest
"Fordite" is an anthropocenic mineral "formed from the built up of layers of enamel paint slag on tracks and skids on which cars were hand spray-painted (a now automated process), which have been baked numerous times. In recent times the material has been recycled as eco-friendly jewelry."

CP Company worked with the Royal College of Art to recreate and update Massimo Osti's "Goggle Jacket" -- a jacket designed for Italy's Mille Miglia open-road endurance race that ran between WWI and WWII. They modernized the materials, rethought some of the fit issues -- a clever flourish reduces bunching while sitting; another moves the watch-window so you can check the time without moving your hands from the steering wheel -- but still managed to produce something that looks simultaneously futuristic and retro. It's a gorgeous piece of clothing, though £879 is too rich for my blood. Read the rest
Ministry of Supply is a Kickstarter-funded, new-materials-based fashion house that produces clothing (to date, men's business clothing) based on new fabrics with exotic dirt/water-shedding properties, breathability, and stretch/give. A lot of this stuff has already made its way into the sportwear world, but it's pretty new in business wear, and the result is things like no-iron shirts; slacks with invisible, breathable crotch-venting; odor-absorbing socks and so forth. The slacks don't get wet in rain and are stretchy ("more elastic than cotton but not as stretchy as spandex"). Read the rest
Ars Technica's Casey Johnston reviews Outlier's Women’s Daily Riding Pants, a technical garment that effectively comprise a pair of jeans for wearing, rather than simply being photographed in. They've got generous pockets, a finish that repels water and dirt; a fast-drying loose weave; a higher cut in the back to prevent plumber's crack, and they stretch in four directions. Johnston's review makes them sound great, and makes me want to try on a pair of the men's version. They run about $200. Read the rest
In a Nature paper called "Solid carbon, springy and light, scientists from Zhejiang University in Hangzhou, China introduce a record-breakingly light aerogel, lighter than helium, only twice as heavy as hydrogen:
Gao Chao's team had already been building macroscopic graphene materials in one and two dimensions; to create the new aerogel, the researchers branched out into the third dimension, using a new method of freeze drying the solutions of carbon nanotubes and graphene to create malleable carbon sponges.
PhD candidate Sun Haiyan explained, "It's somewhat like large space structures such as big stadiums, with steel bars as supports and high strength film as walls to achieve both lightness and strength. Here, carbon nanotubes are supports and graphene is the wall."
The new material is amazingly absorptive, able to suck in up to 900 times its own weight in oil at a rate of 68.8 grams per second — only oil, not water, which means it has massive potential as a cleaning material when it comes to events such as oil spills.

"Ultra Ever Dry" is a nanomaterial spray-coating that is (apparently) insanely hydrophobic, shedding dirt, water and oil. The jaw-dropping product video suggests many possibilities, from extreme hydroplaning sports to odd molecular gastronomy possibilities (though it's not rated food-safe, so caveat sprayer). If you're impatient, just zip the video to 2:00 or so and marvel.
What is it? The company says it's a "coating" that will repel almost any liquid by creating a barrier of air on the surface. They don't say what's in the coating. Whatever it is, the How to Apply This Product video suggests you don goggles, gloves and protective gear when you spray. They claim it will protect in temperatures ranging from -30 degrees Fahrenheit to 300 degrees Fahrenheit, but durability is a question. In the video, they say abrasion might affect performance (which makes me wonder how long a pair of sprayed boots would stay dry if you were on a wet, slippery, rocky hiking trail). It's expensive. The base coat is $57.95 and the top coat is $100.95 a quart. On the other hand, if you dare to spray it on your car windows, you wouldn't need window wipers. Or would the windows get too cloudy? If you sprayed it on a car surface, would it affect the gloss? Probably.

This 2010 video demonstrates the wonderful and intriguing behavior exhibited by water when it is dripped on paper that is coated with "superhydrophobic" aerogel powder. The water forms tiny marbles and races around like it's on a griddle. This looks like it would be a lot of fun to try in person, possibly with some small people in attendance.

A new material developed by scientists at UC Irvine is described as the "world's lightest material," so light it can perch atop a dandelion clock without disturbing the seeds. The material is documented in the Nov 18 Science.
The new material redefines the limits of lightweight materials because of its unique “micro-lattice” cellular architecture. The researchers were able to make a material that consists of 99.99 percent air by designing the 0.01 percent solid at the nanometer, micron and millimeter scales. “The trick is to fabricate a lattice of interconnected hollow tubes with a wall thickness 1,000 times thinner than a human hair,” said lead author Dr. Tobias Schaedler of HRL.
The material’s architecture allows unprecedented mechanical behavior for a metal, including complete recovery from compression exceeding 50 percent strain and extraordinarily high energy absorption.
