Surface Effects on the Piezoelectricity of ZnO Nanowires

open access: yes, 2012
We utilize classical molecular dynamics to study surface effects on the piezoelectric properties of ZnO nanowires as calculated under uniaxial loading.

A continuity property and surface topology [PDF]

open access: yesBulletin of the American Mathematical Society, 1973
Introduction. While studying global properties of spaces of retractions of 2-manifolds, the author was led to a continuity property for conformai mappings of simply connected domains with locally connected boundaries (§1, Theorem 2). Applications are given to the study of spaces of retractions (§2), spaces of retracts (§3), and the Dirichlet problem ...

The effect of cool paints and surface properties of the facade on the thermal and energy efficiency of buildings in a hot and arid climate

open access: yesJournal of Materials and Engineering Structures, 2019
The facade of a building is a decisive factor in the thermal and energy performance of buildings. Its surfaces are considered as zones of heat transfer between the inside and the outside.

A characteristic property of a developable surface [PDF]

open access: yesCommunications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1967
The pitch of a closed developable surface is equaî to the arclengzh of its edge of regression. The aim of this paper is to show that this is characteristic property of a closed developable. viz. that if the pitch of a closed ruled surface is equal to the are- length of its line of striction then the surface is developable.1.
