Process Engineering

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a nanoscale technology for investigating biomolecular processes in single living cells. The new technology enables researchers to monitor and study cellular signaling networks, including the first observation of programmed cell death in a single live cell.

The “nanobiosensor” allows scientists to physically probe inside a living cell without destroying it. As scientists adopt a systems approach to st

The same stuff that stains your coffee mug could reduce pollution in the computer hard-drive industry, while saving drive makers millions of dollars in manufacturing costs.

The compound is derived from the tannin phytochemicals commonly found in plants. Green tea has a lot of them.

John Lombardi, president of Tucson-based Ventana Research Corp. combined phytochemicals from green-tea extract, synthetic proteins and an abrasive to produce a lapping slurry that is three to four times f

Possible uses include biological labeling, laser light, catalysts, memory storage, and relief for physicists

A wish list for nanotechnologists might consist of a simple, inexpensive means – actually, any means at all – of self-assembling nanocrystals into robust orderly arrangements, like soup cans on a shelf or bricks in a wall, each separated from the next by an insulating layer of silicon dioxide.

The silica casing could be linked to compatible semiconductor devices. The

Moscow scientists have managed to do simply and inexpensively something which normally proves complicated and expensive. The concept thought out and then implemented is a device which allows you to check the quality of ground and polished surfaces with unprecedented precision and rapidity and to detect every single defect of such surfaces. The effort has been funded by both the Russian Foundation for Basic Research and the Foundation for Promotion of Small-Size Enterprises in Research and Technical A

Experiment uses biomolecules to write on a gold substrate Duke University engineers have demonstrated that enzymes can be used to create nanoscale patterns on a gold surface. Since many enzymes are already commercially available and well characterized, the potential for writing with enzyme “ink” represents an important advance in nanomanufacturing. This research was funded by the National Science Foundation through a Nanotechnology Interdisciplinary Research Initiative (NIRT) grant.

A safer way to heat food products that retains nutritional qualities, which experts acknowledge has a positive effect on health, is being developed with the help of €693,000 from the Food Quality and Safety Programme of the European Union’s Framework Programme

In most cases, the production of safe food products requires some form of heat treatment and, in traditional heating methods, the result is often a loss of nutritional quality. This is because the heat is generated outside the food an
