A study of the porosity of nuclear graphite using small-angle neutron scattering [PDF]

, 2013
Small angle neutron scattering (SANS) measures porosity in nuclear graphites, including both open pores, caused by escaping decomposition gases, and internal cracks (in coke particles) generated by anisotropic thermal contraction along the c-direction ...

Polymer chain stiffness versus excluded volume: A Monte Carlo study of the crossover towards the wormlike chain model

, 2010
When the local intrinsic stiffness of a polymer chain varies over a wide range, one can observe both a crossover from rigid-rod-like behavior to (almost) Gaussian random coils and a further crossover towards self-avoiding walks in good solvents.

Surface Graphitized Mesoporous Carbon Surpasses the Conductivity-Porosity Trade-Off. [PDF]

Adv Sci (Weinh)
Electrochemical cathodic polarization in molten CaCl2‐NaCl converts mesoporous carbon (MC) into surface‐graphitized mesoporous graphite, simultaneously increasing surface area (397–867 m2/g) and electrical conductivity (26–450 S/cm) without mass loss.

Dissipation and irreversibility in computing

Materials Research Express, 2023
There has been much discussion for decades over the proper concepts of minimum dissipation per logic gate and what is required for computation, as well as early arguments over logically reversible machines.

Stretching Semiflexible Polymer Chains: Evidence for the Importance of Excluded Volume Effects from Monte Carlo Simulation

, 2011
Semiflexible macromolecules in dilute solution under very good solvent conditions are modeled by self-avoiding walks on the simple cubic lattice ($d=3$ dimensions) and square lattice ($d=2$ dimensions), varying chain stiffness by an energy penalty ...

Violation of Porod law in a freely cooling granular gas in one dimension

, 2007
We study a model of freely cooling inelastic granular gas in one dimension, with a restitution coefficient which approaches the elastic limit below a relative velocity scale v.

Novel Higgs decay signals in R-parity violating models [PDF]

, 2008
In supersymmetric models the lightest Higgs boson may decay with a sizable branching ratio into a pair of light neutralinos. We analyze such decays within the context of the minimal supersymmetric standard model with R-parity violation, where the ...
