TITLE
ABSTRACT
Breath figures are the characteristic pattern that water droplets form when condensing on a plane substrate. Its geometrical characteristics and dynamical properties are very uncommon because the growth is constraint on a space dimensionality lower than the droplet dimensionality. When the substrate is decorated (rough), a supplementary constraint is imposed that leads to unusual behaviour. The phenomenon of natural dew has many common characteristics with breath figures. It shows, however, a number of specificities, mainly related to the fact that it is an atmospheric phenomenon limited by radiative cooling. The possibilities of enhancing dew water yield for producing potable water will be addressed.

TITLE
Acoustically Engineered Materials using Acoustic Radiation Force
ABSTRACT
Traditional device fabrication and manufacturing involve lithography, chemical processing, various deposition processes, and self-assembly among others. In some applications, such as designing metamaterials, one requires methods to create 3D patterns of materials where the traditional methods are neither convenient nor possible to use. In the case of acoustic metamaterials, the majority of the materials built so far by researchers elsewhere is in the cm length-scale and use mm-size solid spheres, cavity resonators or other inclusions. Because of the mechanical fabrication techniques used, scaling to smaller length scales is both problematic and difficult. We are exploring an acoustic approach that allows fabrication of novel materials where the length scale can be extended by orders of magnitude, from a few nanometers to 100s of microns. This approach is based on acoustic radiation force to manipulate particles (nano/micro-sized) into a wide range of 3D patterns in a host fluid that can be solidified. This is a bench-top, inexpensive technique and the whole process is rapid (~10s of seconds). The periodicity of the pattern formed is highly tunable. Almost any kind of particle can be used (metal, insulator, semiconductor, superconductor, piezoelectric, hollow or gas-filled spheres, nanotubes and nanowires etc.) The technique can be adapted for large scale manufacturing. Both the types of materials that can be engineered by this approach and thepossible applications of these new materials can be wide-ranging.

Hits to my Blog
East Headwinds and 2011
The big news is correctly summarized this week in Barron’s and represents a turning point for the global economy:
Abelson, Alan, 2010. A double hex. Barron's, Nov. 13.
By the two quotes listed below, I think it is safe to assume that there exists a serious question regarding global growth prospects for 2011:
"China, meanwhile, is facing a flare-up of inflation and, to date at least, its efforts to douse it have not been conspicuously successful, despite the proclivity of the chaps who run the country's command economy to put the best smiley face possible on official numbers. In October, the Sino consumer-price index shot up at a 4.4% annual rate over October 2009 and, as ISI Group points out, a 0.8% jump over the previous month."
"Even more ominous, the money supply, which unless controlled acts as the feedstock of inflation, expanded at a scorching 28.7% annual rate and over the past three years has risen some 24%. Not exactly a big surprise, then, that Chinese banks have been on a lending spree; last month alone, they coughed up $89 billion in new loans."
Bottom line, such a rapid expansion of the Chinese money supply almost guarantees a significant problem with inflation. Further, the issue of new loans to business at a rapid pace probably means greater risk of default. Inflation plus defaults equals significant downward pressure on economic growth. Add a policy of currency pegging to the mix and I think equity markets are correct in anticipating the making of an economic disaster.
Given a stable society were a large percentage gain some advantage from an economic expansion, the three pillars of doom (inflation, defaults, and pegging) might not cause a calamity. However, under different political situations this assumption does not hold.
Alan Abelson captures this point brilliantly in the following quote:
"As we've observed more than once, given the sheer size of China's increasingly testy population, and the yawning gap between the comparatively few in the upper reaches of the income scale and the mass of the citizenry, a delicate balance between keeping smoke curling out of its factories and keeping inflation in check is an imperative. Put us down among the doubters that it can pull off that neat financial trick."
I think it is possible that China's growth could slow along with that of Germany. Given weak American growth, the odds are that 2011 might be another lean year in GDP growth, equity prices, and perhaps even certain commodity prices.
Is it too early to look toward 2012?
