This paper developed an active scanning probe array. The probe array consists of 16×2 probes thermally actuating and sensing. The 32 probes are integrated with Ti/Pt temperature sensors and bimorph thermal actuators. Each probe is a Si3N4 cantilever equipped with a sharp nano scale pyramid tip at its free end. When one of the probes is actuated, its neighboring probes can provide temperature se...

A multilayer-based fiber optic sensor enabling simultaneous measurement of humidity and temperature is proposed and demonstrated. The sensitive elements were multilayer coatings consisting of nano-porous TiO(2) and SiO(2) films, which were deposited on fiber end-face to form a Fabry-Perot (F-P) filter structure. Relative-humidity (RH) sensing is correlated with the shift of interference fringe ...

this study is concerned with the synthesizing of cu-zn nano-ferrite particles in the laboratory applying simple techniques. the morphology of the synthesized nano-particles was analyzed using transmission electron microscopy (tem), and the minerals were identified using x-ray diffraction (xrd). the nano material was used to replace 1- 4 percent by weight of portland cement in cement pastes and ...

A precise and simple in-situ voltammetric measurement of promethazine, based on the nano sized molecularly imprinted polymer (nano-MIP) was introduced. The nano-MIP was synthesized utilizing vinyl benzene and Divinylbenzene as the functional monomer and cross-linker respectively, and via the micro-emulsion polymerization method in silicon oil. The MIP particles were then embedded in a carbon pa...

This paper reports a nano-opto-mechanical pressure sensor based on nano-scaled ring resonator. The pressure is measured through the output spectrum shift which is induced via mechanical deformation of the ring resonator. The sensitivity as high as 1.47 pm/kPa has been experimentally achieved which agrees with numerical prediction. Due to the strong variation of sensitivity with different ring r...

in the present study, the interaction between nano-tio2 and lysozyme was investigated by the method of uv-vis detection and fluorescence spectroscopic techniques. the thermal denaturation of lysozyme has been investigated in the presence and absence of nano-tio2 over the temperature range (293-373) k in different buffer and ph, using temperature scanning spectroscopy. the presence of nano-tio2 ...

Sensitive and selective sensor system is required to detect causes of disease. It is able to detect the cause of the disease more effectively by using multi-modal properties of nano-bio sensors. Some peak detection algorithms which are suitable for implementing with micro-controller are compared to apply to multi-modal nano-bio sensors in this paper. It is shown that autothreshold peak detectio...

We report on the use of combined heating and pulsed UV light activation of indium oxide gas sensors for enhancing their performance in the detection of nitrogen dioxide in air. Indium oxide nano-octahedra were synthesized at high temperature (900 °C) via vapour-phase transport and screen-printed onto alumina transducers that comprised interdigitated electrodes and a heating resistor. Compared t...

A new nanoscale electric field sensor was developed for studying triboelectric charging in terrestrial and Martian dust devils. This sensor is capable to measure the large electric fields for large dust devils without saturation. However, to quantify the electric charges and the field strength it is critical to calibrate the mechanical stiffness of the sensor devices. We performed a technical f...
