Heteroreceptor complexes and their allosteric receptor-receptor interactions in the central nervous system. Focus on examples from Dopamine D2 and Serotonin 5-HT1a receptors [PDF]

, 2018
GPCR interacting proteins (specially β- arrestin) and their receptor-protein interactions are also covered but their interactions with the allosteric receptor-receptor interactions in heteroreceptor complexes remain to be elucidated.

Monte Carlo simulations of the classical two-dimensional discrete frustrated $\phi ^4$ model

, 2003
The classical two-dimensional discrete frustrated $\phi ^4$ model is studied by Monte Carlo simulations. The correlation function is obtained for two values of a parameter $d$ that determines the frustration in the model.

PEDOT:PSS—A Key Material for Bioelectronics

Advanced Science, EarlyView.
PEDOT:PSS ‐ Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate ‐ is typically processed from water dispersions to form multifunctional and multidimensional constructs with tunable electronic and ionic conductivity. Throught processing engineering, PEDOT:PSS is intergrated in bioelectronic devices that operate efficiently in physiological conditions

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi

Advanced Science, EarlyView.
Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

Ab-initio study of disorder effects on the electronic and magnetic structures of Sr$_2$FeMoO$_6$

, 2001
We have investigated the electronic structure of ordered and disordered Sr$_2$FeMoO$_6$ using {\it ab-initio} band structure methods. The effect of disorder was simulated within super-cell calculations to realize several configurations with mis-site ...

Role of local geometry in spin and orbital structure of transition metal compounds [PDF]

, 2015
We analyze the role of local geometry in the spin and orbital interaction in transition metal compounds with orbital degeneracy. We stress that the tendency observed for the most studied case (transition metals in O$_6$ octahedra with one common oxygen --

Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

Advanced Science, EarlyView.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

PARÂMETROS CINÉTICOS DE MOAGEM DE ITABIRITOS COMPACTO E FRIÁVEL

Holos, 2014
Duas amostras de minério de ferro classificadas como itabiritos compacto e friável foram testadas com relação a moabilidade. Os testes foram realizados em um moinho de bolas em escala de laboratório com torquímetro para medição precisa da potência.

Possible ferro-spin nematic order in NiGa2S4

, 2006
We explore the possibility that the spin-1 triangular lattice magnet NiGa2 S4 may have a ferro-nematic ground state with no frozen magnetic moment but a uniform quadrupole moment. Such a state may be stabilized by biquadratic spin interactions.
