The purpose of this study is to demonstrate the construction of Manganese Dioxide (MnO2) Thin-Film on a stainless-steel substrate (AISI304) using the electrodeposition process. A thin MnO2 layer Potentiostatically formed by electrodeposition technique from MnSO4.H2O (aqueous manganese sulphate monohydrated) solution was used to investigate the electrodes’ super-capacitive capabilities. The impact of annealing temperature on the electrochemical characteristics of some materials at temperatures ranging from 100°C-500°C was investigated. The surface morphology of annealed material at 100°C, 200°C, 300°C, 400°C, and 500°C was investigated utilizing a SEM (scanning electron microscope). At 200°C, the cyclic Voltammogram is used to investigate the electrochemical characterisation. The highest value of specific capacitance was calculated from this data and was found to be 184.42F g–1 for 10 mV/s. Utilizing galvanostatic discharging and charging techniques, as well as electrochemical impedance spectroscopy, this research investigates the behaviour of super capacitive materials.

At the end of 2019 and the beginning of 2020, When the Covid -19 pandemic hit the world It effected in all industries even the education sector. The Biggest challenge is to teach the students online the whole world is answered about this new technique. Many existing technologies which are available in Information and Technology world are used for teaching methodology like Google meet, AWW board, Google forms for Exam and so on. But it’s not giving the feel and effect of teaching satisfaction. So the IOT comes in Picture were we can use Robotics and other technologies of IOT for teaching. The plan was ready but the road map is not set so the First action was to examine the equipments which are available to do the all education system online. There are issues with computer systems so alternative option we have to find application searching is started so we get on conclusion we are having smart phones and there are online tool available so we can use them for this procedure. Many ICT tools are there on mobile also so we are started with it and finally we are tried to match the expectation of offline education to Online Education. In this paper we are trying to match and explain the impact of IOT tool and there utilization in education sector with some example.

ATM secured password is multi sequence or multi authentication system which used I for authentication in ATM transactions . Biometric scanning is your "ordinary" mark and Licenses or Vouchers, incription and decription prove your authority. But, some reject to feel tough (Biometric scanning).Mostly written passwords, nowadays, are kept very simple say a mobile number /birthdate. So We Want to Apply This Password At the time of ATM transaction

This paper is related to comparative study of Mno2 and polypyrrole, Mno2 and polypyrrole are separately deposited on two different stainless steel substrate using electrodeposition method, we have studied their super capacitance behaviour using cyclic voltammetry technique and charge discharging curve. We got maximum capacitance value equal to 184.42 F/gm and 29.72 F/gm For MnO2 and Polypyrrole so Mno2 shows better performance than polypyrrole.
