In a new report, "Nanotechnology: A Realistic Market Assessment," BCC Re- search, Wellesley, Mass., forecasts that the global market for nanotechnology is expected to grow to $64.2 billion by 2019, with a five-year compound an- nual growth rate (CAGR) of 19.8%. Nano- devices—the fastest moving segment of the overall market—are anticipated to move at an impressive 34% CAGR, say analysts. The study covers nano- materials (nanoparticles, nanotubes, nanostructured materials, and nano- composites), nanotools (nanolithogra- phy tools and scanning probe micro- scopes), and nanodevices. Nanotechnology, defined as the creation and utilization of materials, devices, and systems through the ma- nipulation of matter at scales of less than 100 nm, continues to have a broad and fundamental impact on nearly all sectors of the global economy, includ- ing the biomedical, electronics, energy, environmental, and pharmaceutical industries. Nanomaterials, particularly nanoparticles and nanoscale thin films, dominated the nanotechnology market in 2013, accounting for 78.8% of the market. This segment is predicted to grow to $52.7 billion by 2019 and regis- ter a 20.7% CAGR. The nanotools category, com- prised of devices used to manipulate or measure nanoscale objects or sub- stances, accounted for 21% of the 2013 nanotechnology market. This segment is expected to reach nearly $11.3 billion by 2019 to register a CAGR of 16.2% However, the nanodevices category, which was valued at just $39 million in 2013, is projected to surge to $183.4 million in 2019. This growth will primarily be driven by increasing con- sumer demand for smaller and more powerful electronic devices, according to the report. "Increased R&D spending in both the private and public sectors is driving development of commercial nanoma- terials applications such as nanocata- lyst thin films for catalytic converters, as well as new and emerging technolo- gies such as nano thin-film solar cells, nanolithographic tools, and nanoscale electronic memory," says analyst An- drew McWilliams. "Rising demand for miniaturization in electronics, as well as public health and environmental concerns, are anticipated to shape sig- nificant growth in this market for the foreseeable future." The report includes analysis of global market trends, with data from 2013, estimates for 2014, and projec- tions of CAGRs through 2019.

("Stress Relief," Nov/Dec 2014). It would be nice to have a more detailed explanation on how the process differs from Wallace Neff's bubble houses. Matt Burr [Wallace Neff inflated a giant bal- loon and applied shotcrete after inflation. The main difference between Neff's approach and our technology is that we cast the concrete in a flat formwork with petal-shaped outlets lying on the ground. After the concrete is hard- ened, the flat plate is transformed into a double-curved shell with the aid of a pneumatic formwork and additional post-tensioning cables in the circumferential direction.—Benjamin Kromoser, Vienna University of Technology] We welcome all comments and suggestions.
