Linear and Nonlinear Mesoscopic Thermoelectric Transport with Coupling to Heat Baths [PDF]

open access: yes, 2016
Decades of research on thermoelectrics stimulated by the fact that nano- and meso-scale thermoelectric transport could yield higher energy conversion efficiency and output power has recently uncovered a new direction on inelastic thermoelectric effects ...

Dynamics of mesoscopic precipitate lattices in phase separating alloys under external load [PDF]

open access: yes, 2000
We investigate, via three-dimensional atomistic computer simulations, phase separation in an alloy under external load. A regular two-dimensional array of cylindrical precipitates, forming a mesoscopic precipitate lattice, evolves in the case of applied ...

Analysis of the ozone profile specifications in the WRF-ARW model and their impact on the simulation of direct solar radiation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Although ozone is an atmospheric gas with high spatial and temporal variability, mesoscale numerical weather prediction (NWP) models simplify the specification of ozone concentrations used in their shortwave schemes by using a few ozone profiles.

Meso-alkynyl porphyrins

open access: yesTetrahedron Letters, 1992
Abstract Porphyrins with meso-alkynyl substituents have been synthesised from trimethylsilyl propynal. Their red-shifted UV spectra and unusual reactivity towards nucleophiles indicate that there is good overlap between the porphyrin π-systems and the triple bonds.
