Diatom Frustules as Substrates for Photocatalysts

Day N., Olsen J., Thiebes J., Polliack A., Diatomix, US

Nanomaterials are quickly becoming highly useful for many applications. The public is concerned with the long-term effects of nanomaterials in the environment. Composite materials as substrates for nanoparticles can be tailored to maintain functionality as [...]

Colored Magnetic Nanoparticles to Improve the Sustainability of Textile Dyeing

Wen J., Sun Y., University of Massachusetts-Lowell, US

Current dyeing techniques face growing environmental and economic challenges due to high consumption of water, salts, auxiliaries and energy, and production of substantial amounts of industrial polluting waste waters. This project demonstrated that colorants can [...]

Molecular Modeling of Low-Emissivity Materials

Schweizer S., Low J.J., Subramanian L., Scienomics, US

Reducing heat transfer through thermal radiation is of main importance for energy efficient building. The emissivity of a material plays a central role in this context. Using low-emissivity (low-e) building materials is a very efficient [...]

Carbon Nanotube Fiber-Based Tensegrity Structures

Zajac D., University of California-Berkeley, US

Tensegrity structures characterized by self-equilibrium and super-stability are space structures, which due to their properties are of interest to architects and civil engineers. This paper reviews the possible usage of carbon nanotube (CNT) fibers as [...]

Recycling of Graphite Waste into High Quality Graphene Products

Ahmed T.M., Rahman M.M., Asmatulu E., Wichita State University, US

Graphite is a stack of carbon layers where carbon atoms form hexagons in a honeycomb structure. Graphene on the other hand is a single atom thick layer which offers unique physical, chemical and biological properties [...]

Nano-layer and micro-structure technologies for energy efficiency and sustainability

Hebrink T.J., 3M Company, US

Multilayer optical film technologies made with hundreds of nanolayers and microstructured film technologies can be used to manage building energy while maintaining architectural aesthetics. For example, visibly transparent (invisible) infrared mirror films are useful for [...]
