“…This is in contrast to the formation of MgO from oximato precursors. Thereby also an amorphous phase is formed first, but forms a textured film upon crystallisation 19. This does not seem to be the case in the present work.…”

“…Indium and tin oximato complexes 14, 15 have not been employed for the fabrication of ITO layers so far. These oximato complexes are very suitable for solution processing due to their good solubility, comparably low decomposition temperatures and absence of any kind of volatility (sublimation) 14, 15, 18, 19. The results of the TG in oxygen are shown in Fig.…”

Indium tin oxide (ITO) thin films can be manufactured by spincoating or inkjet printing of a solution containing indium and tin oximato precursor complexes. After sintering at 600 °C and annealing in reducing atmosphere, resistivities as low as 2.34 × 10−3 Ω cm were observed, with a transparency of more than 95% in the visible region. The employment of an amorphous hafnia interlayer on top of a silicon dioxide dielectric was found to improve the wetting behaviour significantly. Thus source–drain structures could be obtained by inkjet‐printing and field‐effect transistors were constructed using poly(3‐hexylthiophene) (P3HT) as organic semiconductor.

Nanomaterial-based photoluminescence (PL) diagnostic devices offer fast and highly sensitive detection of pesticides, DNA, and toxic agents. Here we report a label-free PL genosensor for sensitive detection of Vibrio cholerae that is based on a DNA hybridization strategy utilizing nanostructured magnesium oxide (nMgO; size >30 nm) particles. The morphology and size of the synthesized nMgO were determined by transmission electron microscopic (TEM) studies. The probe DNA (pDNA) was conjugated with nMgO and characterized by X-ray photoelectron and Fourier transform infrared spectroscopic techniques. The target complementary genomic DNA (cDNA) isolated from clinical samples of V. cholerae was subjected to DNA hybridization studies using the pDNA-nMgO complex and detection of the cDNA was accomplished by measuring changes in PL intensity. The PL peak intensity measured at 700 nm (red emission) increases with the increase in cDNA concentration. A linear range of response in the developed PL genosensor was observed from 100 to 500 ng/μL with a sensitivity of 1.306 emi/ng, detection limit of 3.133 ng/μL and a regression coefficient (R2) of 0.987. These results show that this ultrasensitive PL genosensor has the potential for applications in the clinical diagnosis of cholera.

Synthesis of nanocomposites in nanofield has drawn much attention due to their potential applications in nanoscale electronics and opto-electronic devices. The properties of nanocomposite materials depend not only on the properties of their individual parents but also on their morphology and interfacial characteristics. Thus, nanocomposites promise new applications in many fields such as mechanically reinforced lightweight components, non-linear optics, battery cathodes, nanowires, sensors and other systems 1-4. Metallic nanocomposites could offer distinct advantages over polymeric composites due to the inherent high temperature stability, high strength, high modulus, wear resistance and thermal and electrical conductivity of the metal matrix. Magnesium oxide (MgO) nanoparticle is thermodynamically stable and wide band gap (7.2 eV) material. It has application as a protective layer in plasma display panel 5 , paint, toxic waste water remediation, refractory materials, sensor and superconducting products 6-8. Magnesium oxide is a best candidate for the barrier material in super sensitive low field sensor called Magnetic Tunnel Junction (MTJ) sensors, because of its superior Tunneling magneto-resistance (TMR) value compared to AlOx 9,10. Zinc oxide is a wide bang gap (3.37 eV) semiconductor oxide and it is a promising material for electronic and opto electronic applications such as field emitters,
