Melting double-stranded DNA (dsDNA) is a fundamental part of several biological processes. dsDNA in vivo subject to small tensile forces induced by thermal fluctuations and active Although these general accelerate bond dissociation, recent experimental theoretical studies suggest nontrivial, stabilizing effect force on the duplex (roll-over effect). To investigate ∼pN axial stability, we develo...

Molecular dynamics (MD) simulations including water and counterions are reported on five examples of A-tract DNA oligonucleotide dodecamer duplexes for which crystal structures are available, the homopolymeric duplex sequences poly(dA) and poly(dG), and two related sequences that serve as controls. MD was performed using the AMBER suite of programs for 3 ns on each sequence. These results, comb...

We report fabrication of large area Ag nanowire (NW) film coated using a continuous roll-to-roll (RTR) slot die coater as a viable alternative to conventional ITO electrodes for cost-effective and large-area flexible touch screen panels (TSPs). By controlling the flow rate of shear-thinning Ag NW ink in the slot die, we fabricated Ag NW percolating network films with different sheet resistances...

Future optoelectronic devices and their low-cost roll-to-roll production require mechanically flexible transparent electrodes (TEs) and substrate materials. Indium tin oxide (ITO) is the most widely used TE because of its high optical transmission and low electrical sheet resistance. However, ITO, besides being expensive, has very poor performance under mechanical stress because of its fragile ...

Flatness measurement using shape-rolls has been used in cold rolling mills for a long time. The benefit is obvious since the measured flatness profile can be used directly to control roll bending, tilt and cooling profile. It was therefore integrated in the mill control system at an early stage to control the strip shape against a target I-unit profile. However, since the flatness is also affec...
