Meet Cristal Global, The Titanium Nanoparticle Makers Behind “Wendy”

By now, we hope you’ve met “Wendy”, the winner of the MoMA PS1 Young Architects Program, in person and have basked in her cool presence, frolicked under her misting sprays and water jets, and, most importantly, breathed in the clean air that envelops her. After all, as much as she’s about summer fun and flash, Wendy is set on “redefining” the boundaries of architecture, which includes becoming a “proactive participant in the city’s ecology”. The project moves to accomplish this goal through the groundbreaking catalytic Titanium Dioxide (TiO2) technology that’s embedded in the folded blue fabric that comprises Wendy’s iconic star-burst form.

The titanium nanoparticle-infused spray that coats Wendy’s spiky dress draws NO2 from the air, neutralizing airborn pollutants to clean the sky above the PS1 courtyard. The question we’re left asking is why more architects aren’t applying this technology to their own designs, large or small?

Cristal Global has long been at the forefront of such technology, manufacturing a range of “depollutants” that enables all architecture to purify the air around it. The genius of the company’s patented CristalACTiV™ Photocatalytic Titanium Dioxide chemical technology lies in the ease with which it can be implemented–as in mixed or added to paint or building materials–and maintained–the product is self-cleaning, resisting dirt adhesives that are left to wash away with the rain. These benefits, however, do not undermine the product’s inherent effectiveness, which has been tested and proven to actively neutralize harmful Nitrogen oxides (NOx) from the atmosphere. Continue.

Given its easy integration onto new and existing buildings, the possibilities for application are seemingly endless. The ecological problems that face civilization today dictate that the built environment be more proactive in anticipating and curtailing unsustainable design and practices that work to further exacerbate the fragile environmental balance now in place. In doing so, new social spaces can also be unlocked and opened, expanding the nature of urbanism from its current definition. Simply put, Buildings should do more than look pretty, and the CristalACTiV™ system is one way to go about achieving that goal.

But back to Wendy. This Sunday, July 15, the architects behind the installation–Architizer-sister company Hollwich-Kushner (HWKN)–will moderate a panel discussion in the PS1 courtyard about what makes Wendy work. The event is part of a “Science Fair” that will explore how Wendy does what she does, namely, cleaning the atmosphere around her.

“Cristal is a proud sponsor of Wendy. We are a leading provider of catalytic Titanium Dioxide (TiO2) technology, including photocatalytic technology which can be used in coatings, concrete, ceramics and other construction materials to depollute the air, create self-cleaning surfaces and combat bacteria. With the use of photocatalytic TiO2, Wendy is an example of environmentally proactive architecture and progressive green design and construction.” –Brian Pickett, Director, Performance Chemicals for Cristal Global

Biologists in Kyoto Turn an Entire Crab Shell Transparent

Remember when you discovered that your toothpaste is partially made of seaweed? Well, not too long from now, there’s a chance your iPad could be made of crab shells. According to Ars Technica, biologists in Kyoto University in Japan have turned the shell of a (dead) crab completely transparent, treating the natural object in a brew of acids and chemicals to strip the body of minerals, proteins, lipids, fats, and pigments. After immersing the treated specimen in an acrylic resin monomer, what remains is a ghostly shell form made entirely out of chitin, a translucent long-chain polymer found in abundance in the exoskeletons of crustaceans, as well as in insects, mollusks, and even fungi (but don’t take the hermit crabs’ homes!).

Not only might these intricate, transparent animal shells inspire new sculptural works from artists like Damien Hirst, but the research also introduces exciting new prospects for technology. The material is incredibly heat-resistant, able to withstand high temperatures without expanding or losing stability, and it also boasts high light transmittance. Thus, if crab shells are crushed into powder and reshaped into a composite sheet, or any form for that matter, they can be stripped of their organic substances, made transparent, and function as clear screens and solar cells. The transparent substrate holds promise for next-generation electronics such as flexible, bending displays. Who knows, maybe the iPhone 6 will be in the shape of a clam.
