The Nanomaterial Biological Interactions knowledgebase provides data on biological exposure with nanomaterials.

The NIOSH Nanoparticle Information Library provides data on nanoparticles for occupational safety. The database includes the following information:

• Nanomaterial composition
• Method of production
• Particle size, surface area, and morphology (included scanning, transmission, or other electron micrographic images)
• Demonstrated or intended applications of the nanomaterial
• Availability for research or commercial applications
• Associated or relevant publications
• Points of contact for additional details or partnering

Nanomaterials registry provides biological and environmental data on nanomaterials. The database is being build to provide minimal information on physico-chemical characteristics (PCCs) of registered nanomaterials and will eventually include biological interaction studies and environmental interaction studies.

The CDC webinar Preventing Adverse Health Effects from Nanotechnology will be streamed August 20, 1 PM EDT.



Update: This is a rebroadcast and is well worth viewing. The slides are available and it can be seen on YouTube at anytime.

Industrial Materials data has posted The Natural Graphite Industry in 2012 report describing the production and use of graphite now and in the future. The largest producers are in China and Brazil. The largest market for graphite is refractories, foundries, and crucibles. Graphene flakes are used in EV batteries and is starting to compete with refractories for this material.

Graphenea has a projection of the cost of CVD graphene over time. Presently, graphene costs $15/cm² and is projected to be $1.5/cm² around 2016 in bulk. Graphenea sells a 100 mm Si/SiO₂ wafer for about $1040 which is about $13.2/cm².

Applied Materials has the presentation Precision Materials to Meet Scaling Challenges Beyond 14nm available on the web (pdf). Below 14 nm, silicon will be replaced with SiGe and the transistor structure will look more like finFETs with all around gate structures and vertical tunneling FETs.

A. K. Geim et. al. wrote the new Nature article Van der Waals heterostructures on 2-D materials. The materials include graphene, BN, MoS₂, and many others.

Brookhaven National Labs (BNL) has an interview with Elena Polyakova, CEO, and Daniel Stolyarov, CTO, from Graphene laboratories in the article From Laboratory to Industry: Unlocking the Potential of Graphene. Elana and Daniel describe their graphene research with BNL, and the how the research center helps their work. BNL has a lab working on graphene synthesis and are studying the properties of graphene. The work with BNL helps Elena and Daniel produce laboratory grade graphene supplies for their customers.

The IEEE Spectrum article Graphene gets some competition describes new 2-D materials that are now under study and offer new material properties for high performance electronics. The 2-D materials include:

• Graphene (C)
• Boron Nitride (BN)
• Molybdenum Disulfide (MoS₂)
• Silicene (single layer of Silicon)
• Germanene (single layer of Germanium)
