Nanotechnology New Ventures Competition

I’d like to take a minute and briefly talk about the Nanotechnology New Ventures Competition.  While the winners have been announced, I will touch upon that later.  The competition’s name may sound confusing, but the competition is actually relatively quite simple.  The idea of the competition is to bring together both researchers of the nanotechnology field and local business leaders who know what it takes to make a small business become successful.  The state of Indiana has become a hotbed for the nanotechnology industry and the I’m sure the hope of this competition is to foster that relationship in the attempt to boost the local economy.

Finding Vital Business Statistics Using Technology

Let’s face it, we all need statistics from time to time, whether it’s for a report, a presentation, a proposal, or to settle an argument with the know-it-all in the next office. Stats can drive business goals and provide insights that might be overlooked easily.  Unfortunately, statistics users face two problems: finding them and using them.

Unless you’re an expert which you probably aren’t, finding the right statistics can be very time-consuming, even with all the fancy search tools we have today.  It can become frustrating and a serious waste of time. The general search engines (Google, Ask.com, Yahoo!, MSN Search, etc.) are inefficient with this sort of research. They will often pull up the statistic from somewhere, but it will have no context. For example, I may search for “average annual income” for a region and find it, but what I really need is the average annual income for a period of time for several locations to conduct an analysis and comparison. This is something the search engines usually won’t do. In a sense, they’ll show you the tree when you really need to view the entire forest. Specialized search engines (including FedStats, FirstGov.gov, and search interfaces at agency sites such as the Census Bureau and the Bureau of Labor Statistics) are often more precise and will get you closer to the data in context, but you still face a lot of back-and-forth inspection of complex data sets.

The Evolution of MicroElectronics

The last 25 years have witnessed astonishing advances in the fields of microelectronics and computation. The first integrated circuit microprocessor, the Intel 4004, was able to perform roughly 5000 binary-coded decimal additions per second with a total power consumption of about 10 W (~500 additions per joule) in 1971, whereas modern microprocessors can perform ~3 x [10.sup.6] additions per joule. The 1997 National Technology Roadmap for Semiconductors (1) calls for an additional factor of [10.sup.3] increase in the computational efficiency by the year 2012. If this goal is attained, then performance of the silicon-based integrated circuit will have improved by nearly seven orders of magnitude in 40 years, using energy consumed per operation as a metric, with a single manufacturing paradigm. Although complementary metal oxide semiconductor (CMOS) technology is predicted by many researchers to run into significant physical limitations shortly after 2010 (2), the energy cost of an addition operation will still be nowhere near any fundamental physical limit. A crude estimate of the energy required to add two 10-digit decimal numbers, based on a thermodynamic analysis of nonreversible Boolean logic steps (3, 4) is ~100*k*T*1n(2), which implies that 3 x [10.sup.18] additions per joule can be performed at room temperature without any reversible steps. Thus, there are potentially eight orders of magnitude in computational energy efficiency in a nonreversible machine available beyond the limits of CMOS technology. To achieve these further advances will require a totally different type of computational machinery, but knowing that such a system is in principle possible provides a strong incentive to hunt for it. The requirement for inventing a new technology paradigm has created exciting research opportunities for physical and biological scientists as well as for electrical engineers. Indeed, much of the current interest in interdisciplinary research in areas such as nanofabrication, self-assembly, and molecular electronics is being driven by this search for a new archetype computer.

What is Nanotechnology?

Nanotechnology Definition and The Medical Field

The term nanotechnology is rarely used and even less understood.  So what exactly is nanotechnology?  To get to the root meaning, lets take a look and the origin of the word.  It comes from the greek language and it can be interpreted to mean “dwarf”.  While many people immediately think of product miniaturization in products like cell phones, laptops, tablets, and computer chips, the more commonly known nanotechnology deals with an area of scientific advancement that deals with microscopic particles.   This perfectly describes this “field of science” since it deals with atoms and matter than can’t be seen by most microscopes let alone the naked eye.  In fact, this field of science wasn’t advanced until the invention of microscopes which were powerful enough to give a good inside look in the 1980’s.  Anyways, nanotechnology deals with manipulating and changing at extremely small scales.  Essentially it deals with the overall knowledge of small atoms and molecules which make up the building blocks of life.
