The compressive strain effect on the magnetic ground state and electronic structure of strained GdTiO3 has been studied using the first-principles method. Unlike the cases of congeneric YTiO3 and LaTiO3, both of which become the A-type antiferromagnetism on the (0 0 1) LaAlO3 substrate despite their contrastive magnetism, the ground state of strained GdTiO3 on the LaAlO3 substrate changes from ...

It has been widely accepted that cAMP activates the protein kinase A (PKA) holoenzyme by dissociating the regulatory and catalytic subunits, thus freeing the catalytic subunit to phosphorylate its targets. However, recent experiments suggest that cAMP does not fully dissociate the holoenzyme. Here, we investigate this mechanism further by using small-angle X-ray scattering to study, at physiolo...

Ab initio density functional theory calculations are performed to study the electronic properties of a MoS2 monolayer deposited over a SiO2 substrate in the presence of interface impurities and defects. When MoS2 is placed on a defect-free substrate, the oxide plays an insignificant role since the conduction band top and the valence band minimum of MoS2 are located approximately in the middle o...
