The Simulation of Surface Charge Accumulation on PMMA with Different Surface Roughness in Vacuum
Energy and Power Engineering, 2017 The surface insulation properties of insulating material under DC voltage are closely related to the characteristics of surface charge accumulation, and the surface roughness of these materials has a direct impact on the surface charge distribution in vacuum. Therefore, it is significant to study their connection.

Surface states and charge accumulation states on reconstructed InAs(001) surfaces
Surface Science, 2015 Abstract Using angle-resolved photoelectron spectroscopy, we investigate the electronic structure of InAs(001) surfaces having different stoichiometries, i.e. the indium rich c(8 × 2) / 4 × 2 surface and the arsenic-rich c(2 × 8) / 2 × 4 surface. We also compare surfaces having the same reconstructions but prepared by different techniques; by ion ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Hydrogen on III-V (110) surfaces: Charge accumulation and STM signatures [PDF]
Physical Review B, 2013 The behavior of hydrogen on the 110 surfaces of III-V semiconductors is examined using ab initio density functional theory. It is confirmed that adsorbed hydrogen should lead to a charge accumulation layer in the case of InAs, but shown here that it should not do so for other related III-V semiconductors.
