We show that the commonly known conductor boundary conditions E|| = B⊥ = 0 can be realized in two ways which we call ’thick’ and ’thin’ conductor. The ’thick’ conductor is the commonly known approach and includes a Neumann condition on the normal component E⊥ of the electric field whereas for a ’thin’ conductor E⊥ remains without boundary condition. Both types describe different physics already...

From configuration interaction (CI) ab initio calculations, we derive an effective two-orbital extended Hubbard model based on the gerade (g) and ungerade (u) molecular orbitals (MOs) of the charge-transfer molecular conductor (TTM-TTP)I(3) and the single-component molecular conductor [Au(tmdt)(2)]. First, by focusing on the isolated molecule, we determine the parameters for the model Hamiltoni...

We report the preparation, crystallization, and solid-state characterization of the first member of a new family of tris(1,9-disubstituted phenalenyl)silicon neutral radicals. In the solid state, the radical packs as weak partial pi-dimers with intermolecular carbon...carbon contacts that fall at the van der Waals atomic separation. Magnetic susceptibility measurements indicate approximately 0....

Bi2212 round multifilament wire has good potential for MRI systems designed to operate at 20 K and produce fields greater than 1.5 T. However, Bi2212 conductor is expensive largely due to the costs associated with materials and fabrication. To reduce the cost, we are investigating single restack designs. This approach reduces the silver fraction. It also reduces the amount of processing needed ...

Transient receptor potential vanilloid type 4 (TRPV4) is a calcium-permeable nonselective cation channel, originally described in 2000 by research teams led by Schultz (Nat Cell Biol 2: 695-702, 2000) and Liedtke (Cell 103: 525-535, 2000). TRPV4 is now recognized as being a polymodal ionotropic receptor that is activated by a disparate array of stimuli, ranging from hypotonicity to heat and aci...
