An air purifier is a gadget used to sanitize the environmental air. Various strategies like paper, foam, cotton was utilized now to clean the air contents. In this venture, we involve water as a channel to decontaminate the air. Air tainting is one of the problematic issues in the high-level world. It prompts various non-infectious diseases to do whatever it takes not to spread the sicknesses. The physical gathering referred to in this paper is suitable for sifting indoor toxins like build-up, small particles, smaller than usual particles, smoke, and certain tiny organic entities. The Air purifier uses an Arduino UNO Microcontroller series in which an Analog PH sensor to distinguish the water PH support times and an MQ135 gas sensor to identify various gases were used. Air purifier is a gadget used to purify the air yet nowadays used to screen the air quality. The system involves an LCD screen that informs the client about the air limits and the concept of disinfected air. [ABSTRACT FROM AUTHOR]

Lithium sulfate (Li2SO4) is a well-known ionic conductor being explored for lithium-ion batteries. This study gives an account of the experimental temperature-dependent Raman scattering study of rapidly quenched Li2SO4 in the temperature range: 303 K to 863 K; this temperature range includes the monoclinic to the cubic phase transition of Li2SO4. The investigated sample was prepared using an in-house developed twin-roller rapid quenching set-up. Temperature-dependent Raman frequency shift and bandwidth broadening of the symmetric stretching ν1 mode are discussed in detail with emphasis on the phase transition point. Comparison of the ν1 peak position is made with ionic conductivity data of Li2SO4. [ABSTRACT FROM AUTHOR]

Thermal parameters, glass transition temperature (Tg) and activation energy (Eg) for structural relaxation, are reported for the binary phosphate glasses, xLi2O-(100-x)P2O5 (40≤x≤66.7), prepared by usual melt-quenching and twinroller rapid quenching techniques. The Tg and Eg values are further used to calculate the fragility index (m) to quantify the thermodynamic strength of the glass samples. It is established using the fragility index that the glasses become progressively fragile with an increase in the modifier concentration owing to the reduction of covalent character of the glass matrix.
