General Education Learning Outcomes : Think Critically — identify, define, analyze, interpret, and evaluate ideas, concepts, information, problems, solutions, and consequences. Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct.
There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
The Nanoscale and History of Nanoscience What is nanoscience?
The history of the use of nanoscience. The scientific process. A sense of scale. Mathematics at the Nanoscale Prefixes and units of measure. Significant figures. Scientific notation. Surface verses volume.
Unit conversions. Density and pressure. The fundamental forces at different scales. FDA regulations. Working in the lab, clothing, gloves and goggles.
The under-body panels on the new C7 Chevrolet Corvette are made of nanocomposite carbon. Improved vehicle fuel efficiency and corrosion resistance by building vehicle parts from nanocomposite materials that are lighter, stronger, and more chemically resistant than metal. Nanofilters remove nearly all airborne particles from the air before it reaches the combustion chamber, further improving gas mileage. Nanoparticles or nanofibers in fabrics can enhance stain resistance, water resistance, and flame resistance, without a significant increase in weight, thickness, or stiffness of the fabric.
Water filters that are only nanometers wide can remove nano-sized particles, including virtually all viruses and bacteria. These cost-efficient, portable water treatment systems are ideal for improving the quality of drinking water in emerging countries. Carbon nanotubes have a variety of commercial uses, including making sports equipment stronger and lighter weight.
For example, a tennis racket made with carbon nanotubes bends less during impact, and increases the force and accuracy of the delivery. Nanoparticle-treated tennis balls can keep bouncing twice as long as standard tennis balls. Most sunscreens today are made from nanoparticles that effectively absorb light, including the more dangerous ultraviolet range. They also spread more easily over the skin.
These same nanoparticles are also used in food packaging to reduce UV exposure and prolong shelf life. Many drink bottles are made from plastics containing nanoclays, which increase resistance to permeation by oxygen, carbon dioxide, and moisture.
This helps retain carbonation and pressure and increases shelf life by several months. Biological membranes are by far the most important electrified interfaces in living systems. They consist of a bimolecular layer of lipids the lipid bilayer incorporating proteins. Lipid molecules are amphiphilic , i. In biological membranes the two lipid monolayers are oriented with the hydrocarbon tails directed toward each other and the polar heads turned toward the aqueous solutions that bath the two sides of the membrane.
The resulting lipid bilayer is a matrix that incorporates different proteins performing a variety of functions. Biomembranes form a highly selective barrier between the inside and the outside of living cells.
They are highly insulating to inorganic ions, and large electrochemical potentialdifferences can be maintained across them. Ion channels represent a class of membrane spanning protein pores that mediate the flux of ions in a variety of cell types. They reside virtually in all the cell membranes in mammals, insects and fungi, and are essential for life, serving as key components in inter- and intracellular communication.
Functionality of an ion channel is synonymous with the detection of ion currents. Print ISBN
