The driving mechanism of the metal-insulator transition (MIT) in VO(2) has always attracted attention, in particular with regards to understanding if and how the doping mechanism may tune the MIT transition temperature. However, due to the lack of detailed local structural information, in this oxide the underlying MIT mechanism is ...

Transthyretin has been proposed as nutritional biomarker of selenium intake. Previous transthyretin purification methods used different procedures to isolate transthyretin either from plasma or from pathological urine of humans. In general, the procedure for purification of transthyretin is laborious and expensive, and extensive sample recycling is necessary for purification in ...

Herein, 3D nanohybrid architectures consisting of MnO(x) nanocrystals, carbon nanofibers (CNFs), and graphene sheets are fabricated. MnO(x) -decorated CNFs (MCNFs) with diameters of about 50 nm are readily obtained via single-nozzle co-electrospinning, followed by heat treatment. The MCNFs are then intercalated between graphene sheets, yielding the ternary nanohybrid MCNF/reduced graphene ...

Depletion of cholinergic interneurons in the ventral striatum (nucleus accumbens or N.Acc.) in adult rats increases the locomotor activating effects of amphetamine. It also impairs sensorimotor gating processes, an effect reversed by the antipsychotic haloperidol. These behavioural effects are suggestive of pronounced hyper-responsiveness of the mesolimbic dopamine (DA) projection to ...

The first metal coordination complex of a radical ligand based on the 1,2,3-dithiazolyl heterocycle is reported. 6,7-Dimethyl-1,4-dioxo-naphtho[2,3-d][1,2,3]dithiazolyl acts as a bridging ligand in the volatile trinuclear Mn(hfac)(2)-Rad-Mn(hfac)(2)-Rad-Mn(hfac)(2) complex (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonato-). The Mn(ii) and radical ligand spins are coupled anti-ferromagnetically (AF) resulting in an S(T) = 13/2 spin ground state.
