A dibenzofuran derivative: 2-(pentyloxy)dibenzo[b,d]furan

IUCrData, 2018
The title compound, C17H18O2, crystallizes in two-dimensional sheets, in which the 2-(pentyloxy)dibenzo[b,d]furan molecules are arranged in a head-to-head and tail-to-tail fashion that enables hydrophobic interactions between fully extended 2-pentoxy ...

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 ...

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 ...

Friedel oscillations responsible for stacking fault of adatoms: The case of Mg(0001) and Be(0001) [PDF]

, 2014
We perform a first-principles study of Mg adatom and adislands on the Mg(0001) surface, and Be adatom on Be(0001), to obtain further insights into the previously reported energetic preference of the fcc faulty stacking of Mg monomers on Mg(0001).

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 ...
