Implications of a 20-Hz Booster cycle-rate for Slip-stacking [PDF]

, 2014
We examine the potential impacts to slip-stacking from a change of the Booster cycle-rate from 15- to 20-Hz. We find that changing the Booster cycle-rate to 20-Hz would greatly increase the slip-stacking bucket area, while potentially requiring greater ...

Molecular design of orthogonal stacking system at the complex interface of HtrA PDZ domain with its peptide ligands [PDF]

Journal of the Serbian Chemical Society, 2019
The high temperature requirement A (HtrA) protease plays a crucial role in protein quality control and cell fate. The enzyme contains a catalytic protease domain and a regulatory PDZ domain; the latter determines the substrate specificity of the former ...

Bending modes, elastic constants and mechanical stability of graphitic systems [PDF]

, 2010
The thermodynamic and mechanical properties of graphitic systems are strongly dependent on the shear elastic constant C44. Using state-of-the-art density functional calculations, we provide the first complete determination of their elastic constants and ...

Stacking-dependent electronic structure of trilayer graphene resolved by nanospot angle-resolved photoemission spectroscopy

, 2017
The crystallographic stacking order in multilayer graphene plays an important role in determining its electronic structure. In trilayer graphene, rhombohedral stacking (ABC) is particularly intriguing, exhibiting a flat band with an electric-field ...

Influence of perylenediimide–pyrene supramolecular interactions on the stability of DNA-based hybrids: Importance of electrostatic complementarity

Beilstein Journal of Organic Chemistry, 2014
Aromatic π–π stacking interactions are ubiquitous in nature, medicinal chemistry and materials sciences. They play a crucial role in the stacking of nucleobases, thus stabilising the DNA double helix.
