WELCOME TO NANOTECHNOLOGY

PowerPoint Presentation: 

Nanotechnology is the engineering of tiny machines — the projected ability to build things from the bottom up inside personal nanofactories (PNs), using techniques and tools being developed today to make complete, highly advanced products. Ultimately, nanotechnology will enable control of matter at the nanometer scale, using mechanochemistry . Shortly after this envisioned molecular machinery is created, it will result in a manufacturing revolution , probably causing severe disruption. It also has serious economic, social, environmental, and military implications .

What could nanofactories produce?: 

What could nanofactories produce? Lifesaving medical robots or untraceable weapons of mass destruction. Networked computers for everyone in the world or networked cameras so governments can watch our every move. Trillions of dollars of abundance or a vicious scramble to own everything. Rapid invention of wondrous products or weapons development fast enough to destabilize any arms race.

IS NANOTECHNOLOGY BAD OR GOOD: 

IS NANOTECHNOLOGY BAD OR GOOD

PowerPoint Presentation: 

Nanotechnology offers great potential for benefit to humankind, and also brings severe dangers . While it is appropriate to examine carefully the risks and possible toxicity of nanoparticles and other products of nanoscale technology, the greatest hazards are posed by malicious or unwise use of molecular manufacturing. CRN's focus is on designing and promoting mechanisms for safe development and effective administration of MM.

What is Nanotechnology?: 

What is Nanotechnology? A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale . This covers both current work and concepts that are more advanced. In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up , using techniques and tools being developed today to make complete, high performance products.

Four Generations: 

Four Generations Mihail (Mike) Roco of the U.S. National Nanotechnology Initiative has described four generations of nanotechnology development (see chart below). The current era, as Roco depicts it, is that of passive nanostructures, materials designed to perform one task. The second phase, which we are just entering, introduces active nanostructures for multitasking; for example, actuators, drug delivery devices, and sensors. The third generation is expected to begin emerging around 2010 and will feature nanosystems with thousands of interacting components. A few years after that, the first integrated nanosystems , functioning (according to Roco ) much like a mammalian cell with hierarchical systems within systems, are expected to be developed.

General-Purpose Technology: 

General-Purpose Technology Nanotechnology is sometimes referred to as a general-purpose technology . That's because in its advanced form it will have significant impact on almost all industries and all areas of society. It will offer better built, longer lasting, cleaner, safer, and smarter products for the home, for communications, for medicine, for transportation, for agriculture, and for industry in general.

Benefits of Molecular Manufacturing: 

Benefits of Molecular Manufacturing Advanced nanotech can solve many human problems. Many diverse problems are related to water. Cheap greenhouses can save water, land, and food. Nanotech makes solar energy feasible. Living spaces can be improved. Computers will be cheap enough for everyone. Nanotech can help the environment.
