Other Tech: Antimatter harvesting

Giant wire spheres may one day float near Earth, scooping up bits of antimatter for humans to use as space fuel. This is one of 12 recently selected to each receive up to $75,000 from the NASA Institute for Advanced Concepts. A plan is for antimatter to be collected using three concentric wire spheres. The …

Deterministic chaos found and analyzed in atomic force microscope

Chaotic oscillations of microcantilever tips in dynamic Atomic Force Microscopy (AFM) are reported and characterized. Systematic experiments performed using a variety of microcantilevers under a wide range of operating conditions indicate that softer AFM microcantilevers bifurcate from periodic to chaotic oscillations near the transition from the non-contact to the tapping regimes. Careful Lyapunov exponent and …

Comparing CMOS versus rod-logic and other nanotechnology computing devices

When comparing the costs, performance, energy requirements the additional limitations of CMOS are that you still mainly have fairly large chips that have to be put into fairly large form factor devices. Rod-logic in a pure molecular manufactured systems would have far less size overhead. Rod-logic can be three-dimensional which greatly increases its likely performance. …
