In the present work, we report the room temperature NH3 sensing properties of Cobalt-boride nanoparticles intercalated polyaniline (Co-B-PANI) nanocomposite films. Polyaniline nanocomposite films (PNCF's) have been deposited at room temperatures by in-situ oxidative polymerization of aniline in the presence of Co-B nanoparticles. The PNCF exhibited a highly selective, sensitive and reversible response towards NH3. It exhibited an improved response and recovery times of 3 and 345 s, respectively towards 50 ppm of NH3. The response time in the case of PNCF was found to be better than that exhibited by pure PANI-sensor-films (7 and 400 s). Raman measurements performed before and after the exposure towards NH3 indicated a strong variation in the intensity of the peak corresponding to C=N/C-N+ stretching vibrations. Good sensitivity along with the improved response and recovery times indicated Co-B-PANI nanocomposite film to be suitable for room temperature ammonia sensing applications.

Nanocrystalline tin oxide powder is synthesized using sol gel method. To observe the effect of addition of surfactant on particle size, Sodium Dodecyl Sulphate (SDS) is added during the synthesis. The particle is found to be ~ 8 nm using TEM. The synthesized nanophase tin oxide powder is used to fabricate thick film sensors using screen printing technique. The sensor performance is tested for 100 ppm of LPG. The role of surfactant is observed to be responsible for remarkable improvement in sensitivity for LPG by 5 times with low operating temperature of 110 °c. The optical and structural characterization of powder and film is done using UV-Vis, XRD, SEM; TEM. The repeatability, response and recovery time of the sensors is studied.

Simple, compact, robust and handy device for chemical sensing using microstrip-based metamaterial Complementary-Split-Ring-Resonator (CSRR) is proposed. A pseudo-microfluidic channel is fabricated upon the CSRR pattern to form the sensor. Combination of two liquids namely, ethanol and petrol, and their varying combinations are sensed for hybrid fuel applications. Simulation and experimental results for shifts in resonance frequency and magnitude are discussed. The results of fluidic approach are seen to be repeatable.

Mn has substituted part of Fe in cobalt ferrite (CoFe2O4) and resultant material has been abbreviated as CFMO (CoFe1.7Mn0.3O4). Chemical co-precipitation route has been followed for synthesis. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDX), I-V measurement were performed for sample characterization. The influence of Mn substitution was seen in lowering the operating temperature for both acetone and ammonia gas sensing with high response as well as very fast response and recovery timealong with temperature dependent selectivity.

This research presents a metal functionalized titanium dioxide (TiO2) nanotube based sensor developed for detection of volatile biomarkers (methyl p-anisate and methyl nicotinate) associated with tuberculosis (TB). In this work self-aligning TiO2 nanotubes were fabricated, and functionalized with cobalt for specific binding to the volatile biomarkers of interest. Mimics of the volatile biomarkers were dissolved in water at variable concentrations, and nitrogen gas was flowed through the biomarker solutions and delivered to the sensor. A potentiostatic scan was used to measure current across the device under constant potentials ranging from -1.0 volts to 1-volts methyl nicotinate and methyl p-anisate. The sensor response showed a 3 × 105 change in current for methyl nicotinate, and 7.61 × 106 change in current for methyl p-anisate when compared to baseline. The sensor also showed little response to five other VOCs (acetone, ethanol, methanol, benzene, and phenol) which suggest the sensor is functionalized to be specific for the target VOCs associated with TB. Results showed detection of the volatile biomarkers yield orders of magnitude change in current which is detected easily. The sensor is simple to operate, responds in minutes, and has potential applications in non-invasive diagnosis of TB and other diseases that have distinct volatile biomarkers.

Herein, we report the development of highly water dispersible nanocomposite of conducting polyaniline and multiwalled carbon nanotubes (PANI-MWCNTs) via novel, `dynamic' or `stirred' liquid-liquid interfacial polymerization method using sulphonic acid as a dopant. MWCNTs were functionalized prior to their use and then dispersed in water. The nanocomposite was further subjected for physico-chemical characterization using spectroscopic (UV-Vis and FT-IR), FE-SEM analysis. The UV-VIS spectrum of the PANI-MWCNTs nanocomposite shows a free carrier tail with increasing absorption at higher wavelength. This confirms the presence of conducting emeraldine salt phase of the polyaniline and is further supported by FT-IR analysis. The FE-SEM images show that the thin layer of polyaniline is coated over the functionalized MWCNTs forming a `core-shell' like structure. The synthesized nanocomposite was found to be highly dispersible in water and shows beautiful colour change from dark green to blue with change in pH of the solution from 1 to 12 (i.e. from acidic to basic pH). The change in colour of the polyaniline-MWCNTs nanocomposite is mainly due to the pH dependent chemical transformation /change of thin layer of polyaniline.

The gas sensing characteristics of Cr1-xFexNbO4 (x = 0.0, 0.5, 1.0) towards different organic analytes and hydrogen were investigated at different operating temperatures. The slope of the retrace transient, a representative feature for desorption kinetics was considered for data exploration. 11 sensors with 12 samples were tested and the data obtained was processed using principal component analysis (PCA). The scores plot and loadings plot showed the possible differentiation of the cross sensitive analytes and redundancy of the sensor behaviour towards these analytes respectively.

Ion-Sensitive Field-Effect Transistor (ISFET) is a popular potentiometric chemical/bio-chemical sensor. However, due to charge screening, the sensitivity of the device is significantly reduced. A logarithmic dependence is exhibited between the charge present at the electrolyte-insulator interface and the charge mirrored in the conducting channel, which limits the sensitivity of an ideal conventional ISFET to 59.2 mV/pH, also known as the Nernstian limit. Using Dual-Gate effect in Silicon-on-Insulator (SOI) technology improves the sensitivity of ISFET. MOSFET test structures are generally fabricated along with ISFETs on the same wafer. In this paper, we have demonstrated the dual gate operation of a Near-Fully Depleted (NFD) SOI MOSFET, by simulating its behavior in SILVACO™ TCAD tool and validating it with the test results of fabricated NFDSOI MOSFET. It is observed that the threshold voltage and drain current of the transistor can be manipulated by applying a potential to the back gate.
离子敏感场效应晶体管(ISFET)是一种流行的电位化学/生化传感器。然而，由于电荷屏蔽，器件的灵敏度明显降低。电解质-绝缘体界面上的电荷与导电通道中反射的电荷呈对数依赖关系，这将理想的传统ISFET的灵敏度限制在59.2 mV/pH，也称为纳恩斯特极限。在绝缘体上硅(SOI)技术中引入双栅极效应，提高了ISFET的灵敏度。MOSFET测试结构通常与isfet一起在同一晶片上制造。在本文中，我们通过在SILVACO™TCAD工具中模拟近完全耗尽(NFD) SOI MOSFET的行为，并通过制造的NFDSOI MOSFET的测试结果验证了其双栅极操作。可以观察到，晶体管的阈值电压和漏极电流可以通过对后门施加电势来控制。
