INVERSION SYMMETRY, ARCHITECTURE AND DISPERSITY, AND THEIR EFFECTS ON THERMODYNAMICS IN BULK AND CONFINED REGIONS: FROM RANDOMLY BRANCHED POLYMERS TO LINEAR CHAINS, STARS AND DENDRIMERS

Condensed Matter Physics, 2002
Theoretical evidence is presented in this review that architectural aspects can play an important role, not only in the bulk but also in confined geometries by using our recursive lattice theory, which is equally applicable to fixed architectures ...

Surface polar optical phonon interaction induced many-body effects and hot-electron relaxation in graphene

, 2013
We theoretically study various aspects of the electron-surface optical phonon interaction effects in graphene on a substrate made of polar materials. We calculate the electron self-energy in the presence of the surface phonon-mediated electron-electron ...

Multi-Criteria Framework for Routing on Access Land: A Case Study on Dartmoor National Park

ISPRS International Journal of Geo-Information
Creating routes across open areas is challenging due to the absence of a defined routing network and the complexity of the environment, in which multiple criteria may affect route choice.

Equilibrium and kinetic isotope effects in heterogeneous catalysis: A density functional theory perspective

Catalysis Communications, 2023
Isotopes are indispensable tools for elucidating catalytic reaction mechanisms. Yet, computational isotopic studies in heterogeneous catalysis remain scarce, especially when compared with other subfields of chemistry.

Electrostatic effects and band-bending in doped topological insulators [PDF]

, 2012
We investigate the electrostatic effects in doped topological insulators by developing a self consistent scheme for an interacting tight binding model. The presence of bulk carriers, in addition to surface electrons, generates an intrinsic inhomogeneous ...

On the Convergence of the Electronic Structure Properties of the FCC Americium (001) Surface

, 2006
Electronic and magnetic properties of the fcc Americium (001) surface have been investigated via full-potential all-electron density-functional electronic structure calculations at both scalar and fully relativistic levels. Effects of various theoretical

Potential contributions of noncontact atomic force microscopy for the future Casimir force measurements [PDF]

, 2010
Surface electric noise, i.e., the non-uniform distribution of charges and potentials on a surface, poses a great experimental challenge in modern precision force measurements.
