Meta-Nanotubes are a new generation of carbon nanotubes (CNTs) which result from the chemical transformation of regular CNTs and their subsequent combination with foreign materials (atoms, molecules, chemical groups, nanocrystals) by various ways such as functionalisation, doping, filling, and substitution.
These new nanomaterials exhibit enhanced or new properties, such as reactivity, solubility, and magnetism, which pristine CNTs do not possess. Their many applications include electronic and optoelectronic devices, chemical and biosensors, solar cells, drug delivery, and reinforced glasses and ceramics. Carbon Meta-Nanotubes: Synthesis, Properties and Applications discusses these third generation carbon nanotubes and the unique characteristics they possess. Beginning with a general overview of the subject, this book covers the five main categories of meta-nanotubes, namely: Library Genesis Project : View Resource.

Dye-Sensitized. Edited by Leonid A. Kosyachenko, ISBN 978-953-307-735-2, 492 pages, Publisher: InTech, Chapters published November 09, 2011 under CC BY 3.0 licenseDOI: 10.5772/1757 The second book of the four-volume edition of "Solar cells" is devoted to dye-sensitized solar cells (DSSCs), which are considered to be extremely promising because they are made of low-cost materials with simple inexpensive manufacturing procedures and can be engineered into flexible sheets. DSSCs are emerged as a truly new class of energy conversion devices, which are representatives of the third generation solar technology.
Mechanism of conversion of solar energy into electricity in these devices is quite peculiar. The achieved energy conversion efficiency in DSSCs is low, however, it has improved quickly in the last years. Engineers Edge - Design, Engineering & Manufacturing Solutions. Ground Effect Basics - Hoverwing WIG craft technology. The ground effect physicists name a phenomenon, which is to be observed easily in nature. Particularly water birds, swans or the Albatross use this effect, which facilitates obviously flies for them scarcely over the soil or over the water. Without effort seem the birds there to slide, hardly that they must strike once with the wing. Ground Effect is the most efficient mode of powered flight yet known to man. In nature sea birds such as the Albatross extend their flight range to incredible distances across the oceans.
When an appropriately designed aerodynamic wing is flying close to water or ground, the aerodynamic lift increases due to the creation of a dynamic air cushion under the wing. Flying bodies at ground level experience this phenomenon - ground effect referred to English -: their lift is very many more efficient than in higher air regions.

Evalise. METAL FAB. Digital Composition. Skills. How To Decide What Ideas To Prototype. [Editor’s note: This is the fifth in a series of seven posts on running your own Google Ventures design sprint. Read the first part here, the second here, the third here, and the fourth here.] At the Google Ventures Design Studio, we have a five-day process for taking a product or feature from design through prototyping and testing.
We call it a product design sprint. This is the fifth in a series of seven posts on running your own design sprint. At this point in a design sprint, you’ve got a lot of ideas down on paper. You’ve explored the problem, generated a ton of solutions, and looked around at how other companies are solving similar problems. It’s awesome to have a lot of ideas. Today we’ll look at how to decide which solutions to flesh out, and how you’ll fit them together into something you can rapidly test with users to learn what’s working and what isn’t. Combat the group effect One method is giving “super votes” to the deciders during design critiques, which you did in day 2.
14 Smart Inventions Inspired by Nature: Biomimicry: Nature as R&D Lab. Companies seeking breakthrough products tend to ignore the greatest invention machine in the universe: life’s more than three-billion-year history of evolution by natural selection. What’s missing is a systematic way of capturing nature’s creativity, says Janine Benyus, a biologist, "innovation consultant" and author.
Engineering practices are fractured, Benyus says. Experts in biomimetics study materials; bionics engineers work on prostheses and mechanics. "There was no umbrella term that encompassed everything from agriculture to business," she says. And thus no way to systematize innovation. So she launched what she calls a new discipline, biomimicry, the title of her 1997 book. Benyus has worked since then to popularize and organize ad hoc biomimetic practices that are probably as old as human invention.

Spoken And Unspoken. Home | Paperhouses. Inside The Minds Of 23 Design Stars. The formal critique is probably the most feared and loathed part of art and design school, often ending in tears (or in decisions to just go into accounting instead). But for her thesis project at Maryland Institute College of Art, Christina Beard actually volunteered to have her graphic design work critiqued, over and over again, by 23 of the most successful designers around today, including Maira Kalman, Stefan Sagmeister, Debbie Millman, and Paula Scher. The project is chronicled in her new book, Critiqued: Inside the Minds of 23 Leaders in Design, which reads as part memoir, part interview series, and part survey of how some of today's leading design figures think. Beard’s iterative design experiment worked a bit like the children’s game of telephone. She began by designing a poster with a simple message: Wash Your Hands. It started as an illustration of blue and green hands in a tree-like formation, reaching up, with the message in simple capital letters at the bottom.
