Will Nanotechnology Be Used To Help People In Developing Countries
The applications of nanotechnology will certainly benefit all the developed countries. But will this new technology help the developing countries those nations that have limited resources and whose people live in poor conditions To answer the question, the Canadian Program on Genomics and Global Health CPGGH has a plan to assist those developing countries. The GPGGH is a leading international group that studies nan-otechnology applications. They advocate that nanotechnology applications will...
ExploraVision Project
The Tumor-nator, Mr. Paul Octavio Boubion. Mr. Paul Octavio Boubion is an eighth-grade physical science teacher at the Carl H. Lorbeer Middle School, in Diamond Bar, California. I asked Mr. Boubion to comment on his experiences in the nanotechnology field and the ExploraVision program. Here is what he had to say. I got interested nanotechnology from my brother-in-law, Timothy Ryan, PhD. who is a research scientist at Cornell University. Dr. Ryan is a neurophysicist and has inspired me with his...
Nano Plastic Packaging
Several chemical companies are producing a nanotechnology transparent plastic film for packaging containing nanoparticles of clay. The nanoparticles are integrated throughout the plastic and are able to block oxygen, carbon dioxide, and moisture from reaching fresh meats or other foods. The nanoclay particles also make the plastic lighter, stronger, and more heat-resistant. One company that makes camera film used nanotech to develop antimicrobial packaging for food products. The company is also...
Nano Nano Nano
In this chapter as well as in the others, we will be using terms, such as nanostructures, nanodevices, nanoparticles, nanoscale, nano-medicine, nanowires, nanotubes, nanoengineering, and so forth. The prefix, nano, is used to indicate a tool, an enterprise, a particle, a phenomenon, a project, or a manufactured item operating on or concerned with a scale at one billionth of a meter. If you have time, you may want to watch the video, What is Nanotechnology Professor Wendy Crone narrates the...
NANO INTERVIEW PROFESSOR MAKARAND MAK PARANJAPE PhD GEORGETOWN UNIVERSITY
As you learned in earlier chapters and in this one, biosensors have the potential to be used in several fields including human health and food preparation. In this interview, Dr. Paranjape discusses his work Synthetic zeolites are widely used as catalysts in the petrochemical industry. Professor Paranjape's Micro and NanoSystems Group. From left to right Jonathan Hesson researcher , Jianyun Zhou Ph.D. candidate , Vincent Spinella-Mamo Ph.D. candidate , Yogesh Kashte researcher , Sean Flynn...
Nano Bar Codes Detect Foodborne Diseases
Another kind of sensor technology is the nano bar code. Nano bar codes are similar to the traditional bar codes that are found on many packaged food products today. However, the nano bar codes, containing metal nanoparticles, could be used to detect pathogens. The nanopar-ticles have specific, recognizable chemical fingerprints that can be read by a machine, an ultraviolet lamp, or an optical microscope. Using these kinds of bar codes, a supermarket checkout computer can identify thousands of...
Ionic Bonding
Atoms can lose or gain electrons forming an ion, which has a net electric charge. A negative charged ion, called an anion pronounced AN-ion , is formed when an atom or a special group of atoms gains additional electrons. When an atom loses some electrons, a positive charged ion is created called a cation pronounced CAT-ion . Ionic bonding takes place between two oppositely charged ions, an anion and a cation. Ions may consist of a single atom or multiple atoms, in which a group of atoms is...
Early Atomic Theory by Empedocles and Democritus
Empedocles was a Greek philosopher and scientist who lived in Sicily between 492 B.C. and 432 B.C. One of his theories was to describe things around us. Empedocles proposed that all matter was composed of four elements fire, air, water, and Earth. As an example, stone was believed to contain a higher amount of Earth than the other elements. The rabbit was believed to contain a higher amount of both water and fire than the other two elements. Another Greek philosopher, Democritus, who lived from...
What Is Nanotechnology
Nanotechnology is the ability to observe, measure, manipulate, and manufacture things at the nanometer scale. A nanometer nm is an SI Systeme International d'Unites unit of length 10-9 or a distance of one-billionth of a meter. That's very small. At this scale, you are talking about the size of atoms and molecules. To create a visual image of a nanometer, observe the nail on your little finger. The width of your nail on this finger is about 10 million Table 1.1 Some Common Objects in Nanometers...
