Magnetic susceptibility measurements are often the first characterization tool that researchers turn to when beginning to assess the magnetic nature of a newly discovered material. Breakthroughs in instrumentation have made the collection of high quality
1). It is well known that cAMP binding induces a clam-like shell closing of the αC helix in CNBDs45 (Extended Data Fig. 8b). This likely rearrangement seems to have displaced polar residue interactions between the cytoplasmic end of S4 and the αC and αD helices in the CNBD (Fig....
The acoustic wave induces a surface displacement normal to or within the surface in the range of a few angstroms to a few nanometres, depending on the applied powers and the frequency of the waves. When acoustic energy and momentum are coupled into the fluid, a net pressure, p, forms in...
A substantially constant electric field supplied by a DC source is applied across the fluid channel and induces translocation of the molecule within the system. An oscillating electric parameter (e.g. current or voltage) supplied by an AC source is also applied across the fluid channel as a ...
This hybridization induces a π–π* state degeneracy and the formation of new energy states between the π states and the 2p orbital of O. Our Bader charge analysis also verified this finding (Fig. 6c), and the C atoms bonded to O atoms have less charge thus acting as a donator of ...
Thus, electron transfer takes place until the Fermi levels of the two materials coincide with each other through changing it by a value ∆ (Fig. 5b). Due to the charge transfer, a potential difference (E z) is created between the surfaces (Eq. 2), where E is the electric field that...
Planetary magnetic fields provide a window into the otherwise largely inaccessible dynamics of a planet’s deep interior. In particular, interaction between fluid flow in electrically conducting interior regions and the magnetic field there gives rise to
Field-assisted self-assembly, motion, and manipulation of droplets have gained much attention in the past decades. We exhibit an electric field manipulation of the motion of a liquid metal (mercury) droplet submerged in a conductive liquid medium (a solu
