Electrical Double Layers
Many biological molecules and common surfaces carry an electrical charge. For example, DNA has a strong negative charge, and so does an amorphous form of silicon dioxide known as silica, the material most people recognize as “glass.” A charged molecule or surface, along with the electrically compensating layer of ions in the adjacent solution, is known as the electrical double layer (EDL).
Multi-scale Loading
A Cleveland Clinic research team is developing virtual models of human knee joints to better understand how tissues and their individual cells react to heavy loads – virtual models that someday can be used tounderstand damage caused by the aging process or by debilitating diseases, such as osteoarthritis.
