Nanofiltration of Electrolyte Solutions by Sub-2nm Carbon Nanotube Membranes

Fornasiero F., Park H.G., Holt J.K., Stadermann M., Kim S., In J.B., Grigoropoulos C.P., Noy A., Bakajin O., Lawrence Livermore National Laboratory, US

Both MD simulations and experimental studies have shown that liquid and gas flow through carbon nanotubes with nanometer size diameter is exceptionally fast. For applications in separation technology, selectivity is required together with fast flow. [...]

Templated virus deposition: from molecular-scale force measurements to kinetic Monte Carlo simulations

Elhadj S., Gilmer G.H., Friddle R.W., Estrada M., Manchester M.E., Johnson J.E., De Yoreo J.J., Noy A., Lawrence Livermore National Laboratory, US

The use of macromolecular scaffolds for hierarchical organization of molecules and materials is a common strategy in living systems that leads to emergent behavior. One characteristic of this strategy is that it generates micron-scale structures [...]

A High-Flux, Flexible Membrane with Parylene-encapsulated Carbon Nanotubes

Park H.G., In J., Kim S., Fornasiero F., Holt J.K., Grigoropoulos C.P., Noy A., Bakajin O., Lawrence Livermore Natioanal Laboratory, US

We present fabrication and characterization of a membrane based on carbon nanotubes (CNT) and parylene. Carbon nanotubes have shown orders of magnitude enhancement in gas and water permeability compared to estimates generated by conventional theories [...]

A Micro Cantilever-based Pathogen Detector

Weeks B.L., Camarero J., Noy A., Miller A.E., Stanker L., De Yoreo J.J., Lawrence Livermore National Laboratory, US

Increasing efforts have been put into the developments of cantilever-based micro sensors. These devices show fast responses, high sensitivity, and are suitable for mass production. Currently, they are mainly applied for quality and process control, [...]

Assembly of Oriented Virus Arrays by Chemo-Selective Ligation Methods and Nanolithography Techniques

Camarero J.A., Cheung C-L, Lin T., Johnson J.E., Weeks B.L., Noy A., De Yoreo J.J., Lawrence Livermore National Laboratory, US

Many experimental techniques in biology and biophysics, and applications in diagnosis and drug discovery, require proteins immobilized on solid substrates. In fact, the concept of arrays of proteins attached to a solid support has attracted [...]

Using Pseudo Transient Continuation and the Finite Element Method to Solve the Nonlinear Poisson-Boltzmann Equation

Shestakov A.I., Milovich J.L., Noy A., Lawrence Livermore National Laboratory, US

The nonlinear Poisson-Boltzmann (PB) eequation is solved using Pseudo Transient Continuation. The PB solver is constructed by modifying the nonlinear diffusion modeule of a 3D, massively parallel, unstructured grid, finite element, radiation-hydrodynamics code. The solver [...]
