This paper gives a statistical view about important contributions and advances on semiconductor metal oxide （SMO） compounds based gas sensors developed to detect the air pollutants such as liquefied petroleum gas （LPG）, H2S, NH3, CO2, acetone, ethanol, other volatile compounds and hazardous gases. Moreover, it is revealed that the alloy/composite made up of SMO gas sensors show better gas response than their counterpart single component gas sensors, i.e., they are found to enhance the 4S characteristics namely speed, sensitivity, selectivity and stability. Improvement of such types of sensors used for detection of various air pollutants, which are reported in last two decades, is highlighted herein.

Context: Bitter melon (Momoradica charantia) is one of the well-known plants used for lowering blood glucose since antiquity. Aims: To compare the efficacy and safety of PDM011011 capsule (1200 mg/day) with Metformin (1000 mg/day) in a 15 weeks study using mean change in fasting plasma glucose (FPG) and Hb1Ac% in subjects with type 2 diabetes mellitus (T2DM). Settings and Design: This is an open-label, randomized, active-controlled, multicentric, phase III study. Methods and Material: A total of 123 eligible patients were randomized in 2:1 ratio in PDM011011 and Metformin arm. Total 83 subjects received PDM011011 capsule (1200 mg/day) and 40 subjects received Metformin (1000 mg/day) in their respective arms for 15 weeks. Subjects were analyzed for FPG and Hb1Ac% at baseline and during treatment visits (visit 3 to visit 7). Safety assessments were carried out. Results: In this study, the significant reduction in mean FPG level was observed after treatment with PDM011011 capsule and Metformin in T2DM patients. The mean change from baseline to week 15 in FPG was 14.52 mg/dL (95% CI: 6.36, 22.67) in the PDM011011-treated subjects and 28.34 mg/dL (95% CI: 21.35, 35.32) in the Metformin-treated subjects. At week 15, the mean change from baseline in HbA1c levels was 0.27% (95% CI: 0.06, 0.47) in the PDM011011 arm and 0.62% (95% CI: 0.40, 0.83) in the Metformin arm. Conclusion: PDM011011 capsule (1200 mg/day) exhibited the modest efficacy and safety as compared to Metformin (1000 mg/day) in type 2 diabetes patients.

The low ion energy argon plasma was used for surface modification of Poly tetra fluoroethylene (PTFE) polymer. The plasma was generated between two plane metal electrode by using 50 kHz bipolar power supply. The plasma treated surface was characterized by atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The surface free energy (SFE) of plasma treated surface was calculated from contact angle measurement. SFE increases from 33.39 mJ/m2 to 41.40 mJ/m2 with the increase in plasma treatment time and the corresponding contact angle changed from 76? to 60?. XPS study shows that F/C ratio change from 1.8 (untreated) to 1.3 (treated) and O/C ratio changes from 0.094 (untreated) to 0.148 (treated). The XPS analysis shows that both F1s and the C1s spectra for PTFE are marginally modified by plasma treatment. AFM study shows that the average surface roughness (Ra) increased from 8.5 nm to 22.8 nm after plasma treatment. vicker’s micro hardness of the film increases upon plasma treatment. The increase in SFE after plasma treatment is attributed to the functionalization of the polymer surface with hydrophilic groups as supported from the above observations.

We report here the influence of thickness on the photosensing properties of copper sulfide (CuS) thin films. The CuS films were deposited onto glass substrate by using a simple and cost effective chemical bath deposition method. The changes in film thickness as a function of time were monitored. The films were characterized using X-ray diffraction technique (XRD), field emission scanning electron microscopy (FE-SEM), optical measurement techniques and electrical measurement. X-ray diffraction results indicate that all the CuS thin films have an orthorhombic (covellite) structure with preferential orientation along (113) direction. The intensity of the diffraction peaks increases as thickness of the film increases. Uniform deposition having nanocrystalline granular morphology distributed over the entire glass substrate was observed through FE-SEM studies. The crystalline and surface properties of the CuS thin films improved with increase in the film thickness. Transmittance (except for 210 nm thick CuS film) together with band gap values was found to decrease with increase in thickness. I-v measurements under dark and illumination condition show that the CuS thin films give a good photoresponse.
