Ullas S., Upadhyay, S., Chandran, V., Pradeep, S., and Dr. T. M. Mohan Kumar, “Control Console of Sewage Treatment Plant with Sensors as Application of IOT”, in 2020 11th International Conference on Computing, Communication and Networking Technologies (ICCCNT), 2020.[Abstract]

Sewage generally consists of black-water, grey-water, toilet-paper, detergents and soap. The manual STP plant collects the sewage in a collection tank where the sewage is left to settle. Then it is mixed with oxygen in aeration tank in order to speed up the bio-degradation process. Finally its is mixed with activated carbon and left in the sedimentation tank to settle down. Sensors have been used in machines and systems to make them automatic. They read the data in real time and provide the system a method to utilize the values and make decisions thus making them automatic. The project involves using the sensors to make the traditional STP more robust and efficient. Different quality parameters such as pH, colour, turbidity, TSS, BOD, COD, TOC, pathogen count etc., are used for measuring the quality of treated water. Determining decisive parameters such as TSS, BOD, COD, TOC involve either expensive instrumentation, lengthy procedure or they are time consuming up to 3 days like for BOD. Using any of these parameters to measure the quality of treated water is not feasible as we need to monitor the parameters instantaneously. By monitoring the quantities of gases such as CO2, CH4 and NH3 that are released during aeration process, it is possible to instantaneously account for the extent of treatment that is taking place at any given point of time.

Dr. T. M. Mohan Kumar and Rao, P. D., “Impedance analysis of Sodium alginate : Graphene oxide composite”, IOP Conference Series: Materials Science and Engineering, vol. 310, p. 012150, 2018.[Abstract]

Sodium alginate (SA) and graphene oxide (GO) composite pellets are prepared by one step simple procedure. The composites are found to be thermally stable up to 220°C in nitrogen atmosphere. The composite was studied for impedance analysis with varying temperature ranging from room temperature to 170°C. Dielectric constant of the samples was measured using the impedance data using standard formulae. It was found that the dielectric constant of the composites is high at low frequencies which may be due to the contribution from all the dipoles responding to the applied signal. However, at high frequencies, may be due to non-participating dipoles, the dielectric constant of the composites is lower.

B.L. Bhaskar, S. Anil Kumar, and Dr. T. M. Mohan Kumar, “Spectrophotometric evaluation of trace level chromium in alloy steel”, Asian Journal of Chemistry, vol. 29, pp. 1917-1919, 2017.[Abstract]

A facile and highly responsive spectrophotometric method for the quantification of ultra-trace quantities of chromium(VI) is described. The proposed method is derived from the oxidation of iminodibenzyl (IDB) with chromium in strong acid medium to get a blue coloured product, having λmax at 690 nm. Stability of the colour developed is found to be around 48 h at room temperature. Beer’s law range is observed between 0.02-0.35 µg mL-1 of chromium concentration. The coefficients of molar absorptivity and Sandell’s sensitivity are found to be 1.03 × 105 L mol-1 cm-1 and 0.000523 µg cm-2, respectively where as the detection limit is 0.9 ng mL-1. The method has been optimized for reaction conditions and optical parameters. Tolerance limits for various interfering ions were studied. The efficiency of the method was shown by successful determination of traces of chromium in alloy steel samples. © 2017, Chemical Publishing Co. All rights reserved.

Nanocrystalline ZnO (n-ZnO) particles are synthesized by in-situ sol-gel method, stabilized using sodium alginate (SA) polymer and impregnated into bentonite (Bt) clay matrix by one pot synthesis. Different nanocomposites of n-ZnO are prepared by alkaline hydrolysis of zinc acetate as precursor by varying the concentration of sodium hydroxide. The effect of Bt on the characteristics of n-ZnO was studied. The average particle size of n-ZnO was calculated to be 14-23 nm by XRD analysis which is matching with the TEM values. TEM images clearly showed the influence of Bt on the shape of particles in which 45SA showed ZnO nanorods due to the stabilization effect of SA. Whereas, spherical ZnO nanoparticles are exhibited by 45SA-Bt due the restriction of n-ZnO growth by the interlayers of Bt. We found that the nanocomposites exhibited excellent bacterial resistance towards both Gram negative (E. coli) and Gram positive (S. aureus) bacteria. The bacterial resistance of nanocomposites is slightly more than that of pure n-ZnO. The results of this study proved that the synthesized n-ZnO and its nanocomposites can be used for various application such as antibacterial, semiconducting etc. More »»

Quality changes in flue cured large cardamom capsules and seeds were monitored under 3 storage conditions: i) 90% RH/38° C (accelerated-humid), ii) 30-40% RH/40° C (accelerated- dry), and iii) 65% RH/27° C (normal) in different packages. The samples were analysed for moisture content, volatile oil content and flavour composition every 30 days for condition (i) upto 120 days and for conditions (ii) and (iii) every 60 days up to 240 days. Capsules packed in unlined high density polyethylene (HDPE) woven sack material, polypropylene ...
