Martin Amis, a former bad boy of British literature, was interviewed last year by the New York Times about his reading habits. Asked which genres he enjoys and avoids, replied, “I confess I have never read an Aga saga or bodice ripper—or indeed western (though Hitler, incidentally, nothing else).”What, you might ask, is saga? The term coined in 1992 to describe novels Joanna Trollope, which, be...

PURPOSE Immune system of some autistic patients could be abnormally triggered by gluten/casein assumption. The prevalence of antibodies to gliadin and milk proteins in autistic children with paired/impaired intestinal permeability and under dietary regimen either regular or restricted is reported. METHODS 162 ASDs and 44 healthy children were investigated for intestinal permeability, tissue-t...

Zn-ion batteries are emerging energy storage systems eligible for large-scale applications, such as electric vehicles. These batteries consist of totally environmentally-benign electrode materials and potentially manufactured very economically. Although Zn/α-MnO2 systems produce high energy densities of 225 Wh kg(-1), larger than those of conventional Mg-ion batteries, they show significant cap...

UNLABELLED Graphene has attracted much attention since it was firstly stripped from graphite by two physicists in 2004, and the supercapacitor based on graphene has obtained wide attention and much investment as well. For practical applications of graphene-based supercapacitors, however, there are still many challenges to solve, for instance, to simplify the technological process, to lower the ...

Although manganese oxide- and graphene-based supercapacitors have been widely studied, their charge storage mechanisms are not yet fully investigated. In this work, we have studied the charge storage mechanisms of K-birnassite MnO2 nanosheets and N-doped reduced graphene oxide aerogel (N-rGOae) using an in situ X-ray absorption spectroscopy (XAS) and an electrochemical quart crystal microbalanc...

We have studied the microstructure, surface states, valence fluctuations, magnetic properties, and exchange bias effect in MnO2 nanowires. High purity α-MnO2 rectangular nanowires were synthesized by a facile hydrothermal method with microwave-assisted procedures. The microstructure analysis indicates that the nanowires grow in the [0 0 1] direction with the (2 1 0) plane as the surface. Mn(3+)...

The thrust to develop eco-friendly procedures for the production of nanoparticles arises from the extremely recent nanotechnology research. MnO2 nanoparticles were synthesized by co-precipitation method using green chemistry. The size, structure and morphology of MnO2 nanoparticles were characterized by UV-Visible, X-Ray diffraction (XRD), FTIR techniques. The average particle size of manganese...

Ti nanowire arrays (NAs) prepared by a facile and template-free hydrothermal method were used as three-dimensional (3D) current collectors for the electrodeposition of MnO2. The resulting Ti@MnO2 NAs exhibit remarkable electrochemical behavior with high specific capacitance, good rate performance and desired cycling stability.

In this work, a sensitive electrochemical aptasensor for the detection of thrombin (TB) is developed and demonstrated based on the co-catalysis of hemin/G-quadruplex, platinum nanoparticles (PtNPs) and flower-like MnO2 nanosphere functionalized multi-walled carbon nanotubes (MWCNT-MnO2).

We propose a novel template-assisted strategy to prepare nanometer-sized manganese oxide (nano-MnO2) by self-assembly of some MnO2 platelets and demonstrate its application as a new class of biosensing platform for probing DNA hybridization and aptamer-target interaction in a homogeneous solution.
