DNA hybridization onto DNA-functionalized nanoparticle surfaces (e.g., in the form of a spherical nucleic acid (SNA)) is known to be enhanced relative free solution. Surprisingly, via isothermal titration calorimetry, we reveal that this enhancement enthalpically, as opposed entropically, dominated by ∼20 kcal/mol. Coarse-grained molecular dynamics simulations suggest observed enthalpic results from structurally confining on surface and preventing it adopting enthalpically unfavorable...
Organic crystals formed by small molecules can be highly functional but are often brittle or insoluble structures with limited possibilities for use processing from a liquid phase. A possible solution is the nanoscale integration of polymers into organic without sacrificing long-range order and therefore function. This enables to benefit advantageous mechanical chemical properties polymeric component. We report here on strategy in which cocrystallize side chains chemically disordered create...
In this study, we have investigated the fluctuations of particle motion, i.e. non-affine during avalanche process, discovering a rich dynamic from microscopic to macroscopic scales. We find that there is strong correlation between magnitude velocity fluctuation and in spatial temporal domains. The possible connection finding theory shear transformation zones discussed based on direct measurement T1 events. addition, system stress are strongly temporally correlated. Our will pose challenges...
Modern particle-based simulations increasingly incorporate polarization charges arising from spatially nonuniform permittivity. For complex dielectric geometries, calculation of these induced many-body effects typically requires numerical solvers based upon boundary-element methods, which very significantly increase the required computational effort. special case spheres, such as colloids or nanoparticles, we recently proposed a semianalytical spectrally accurate hybrid method that combines...
Spontaneous pattern formation plays an important role in a wide variety of natural phenomena and materials systems. A key ingredient for the occurrence modulated phases is presence competing interactions, generally different physical origins. We demonstrate that dipolar films, prototypical system formation, patterns can be induced by dielectric effects alone. rich phase diagram arises, where striped circular morphologies emerge with geometric properties controlled through variation particle...
Abstract We have investigated the spatiotemporal chaotic dynamics of unjamming and jamming particles in a model experiment – rotating drum partially filled with bidisperse disks to create avalanches. The magnitudes first Lyapunov vector δ u ( t ) velocity v are directly measured for time yield insights into their spatial correlation C , which is on statistical average slightly larger near than value transition. These results consistent recent work Banigan et al (Nature Phys. 2013) it...
