Nanotechnology is the result of the continuing technological trend toward device miniaturization and the characterization, manipulation, and fine control of structure and function at diminishing length scales. A large class of nanoscale materials can be stable even though they are far from the lowest-energy thermodynamic state, and many possess novel properties unattainable in bulk. These trends are supported by the increasing sophistication of characterization and fabrication tools such as the scanning tunneling microscope and the transmission electron microscope, which allow the...

Our daughter Grace is a special needs child, and her life is full of challenges. Because of her illness, her intellectual development was hindered, and there is a certain amount of stubbornness as well. Yet the Lord blesses her, using her stubbornness as a positive trait. She has a warrior spirit, never giving up and always facing her illness fearlessly. Grace was on an extremely restricted diet, but she seldom complained or whined for the food that she could not take. She never complained about doing blood work, because she wanted to be a brave example to the other children around.
