A composition includes a carbon nanotube (CNT)-infused carbon fiber material that includes a carbon fiber material of spoolable dimensions and carbon nanotubes (CNTs) infused to the carbon fiber material. The infused CNTs are uniform in length and uniform in distribution. The CNT infused carbon fiber material also includes a barrier coating conformally disposed about the carbon fiber material, while the CNTs are substantially free of the barrier coating. A continuous CNT infusion process includes: (a) functionalizing a carbon fiber material; (b) disposing a barrier coating on the functionalized carbon fiber material (c) disposing a carbon nanotube (CNT)-forming catalyst on the functionalized carbon fiber material; and (d) synthesizing carbon nanotubes, thereby forming a carbon nanotube-infused carbon fiber material.

A mechanism is provided for ratcheting a double strand molecule. The double strand molecule is driven into a Y-channel of a membrane by a first voltage pulse. The Y-channel includes a stem and branches, and the branches are connected to the stem at a junction. The double strand molecule is slowed at the junction of the Y-channel based on the first voltage pulse being weaker than a force required to break a base pair of the double strand molecule. The double strand molecule is split into a first single strand and a second single strand by driving the double strand molecule into the junction of the Y-channel at a second voltage pulse.
