“…The magnetic contribution from the substrate has been subtracted from the data. Two magnetic transitions were observed at T 1 ¼ 122 K and T 2 ¼ 44 K. In a previous study, it was reported that Mn 3 O 4 undergoes a ferrimagnetic transition at $42 K. 12 In our sample, the impurity Mn 3 O 4 was detected in the XRD pattern. Therefore, the magnetic transition at T 2 should be attributed to Mn 3 O 4 ferrimagnetic ordering.…”

Multiferroic Bi 2 NiMnO 6 nanoparticles were synthesized by a simple electrospray method. Bi 2 NiMnO 6 nanoparticles crystallize in the monoclinic structure with space group C121. The particles show a uniform spherical shape with a diameter of 100 nm to 300 nm. The ferromagnetic transition of Bi 2 NiMnO 6 is confirmed at 122 K. The room temperature ferroelectricity of the Bi 2 NiMnO 6 nanoparticles is verified by Kelvin probe force microscopy.

“…This probe has been studied also as [124I]IMPY and high binding ability and specificity to hippocampus and frontal cortex of two AD mouse models (Tg2576 and TT transgenic mice) has been found by in vitro autoradiography [34]. Moreover, although IMPY binds to the Aβ protein, some studies suggested that it could also bind to proteins associated with prion disease.…”

AD is the most common form of dementia among the aging population. The neuropathological alterations of AD are represented by the neurofibrillary tangles and extracellular amyloid plaques formation. These two hallmarks are routinely used as biomarkers for AD diagnosis and can allow the identification of the pathology in a late phase. The urgent need to develop probes for PET analysis that can be used in an early diagnosis of this disorder opened a new scenario in which new biomarkers involved in the first step of AD can be easily detected. Recently, an increasing number of studies indicated as new biomarkers P-gp, TLR4, MIR and free serum copper that are involved in the onset of AD. It has been extensively reported that a P-gp dysfunction in brain can be considered one of the causes of the AD accumulation in brain parenchyma and that the up-regulation of inflammatory gene expression and inflammatory signaling due to MIR and TLR4 modulated the development and the progression of AD.

“…There are many ways available for Mn 3 O 4 preparation, such as meteorological growth [9], radiation [10], electric arc furnace [11], co-precipitation [12], and hydrothermal/solvothermal synthesis [13]. Among them, hydrothermal/solvothermal method possesses advantages of mild reaction condition and well-controlled size, morphology and structures, which has been adopted successfully in the synthesis of various nanometer-sized oxides, metals, semiconductors and magnetic compos-ites [14,15].…”

Monodisperse Mn3O4 nanoparticles were prepared solvothermally starting from manganese acetate by using polyether amide block copolymers (Pebax2533) as a template in isopropanol. The diameter of the nanoparticles in the range of 8.7 nm∼31.5 nm was decreased with increase of Pebax2533 concentration. The electrochemical properties and application in supercapacitor of Mn3O4 nanoparticles were further studied. The results showed that smaller nanoparticles had a larger capacitance. The higher capacitance of 217.5 F/g at a current density of 0.5 A/g was obtained on 8.7 nm Mn3O4 nanoparticles. The specific capacitance retention of 82% was maintained after 500 times of continuous charge-discharge cycles.
