<div class="section abstract"><div class="htmlview paragraph">Urban areas around the world are facing an increasing number of issues, such as air pollution, parking shortages, traffic congestion and inadequate transit options, all of which necessitate innovative solutions. Lot of people are becoming interested in micromobility in urban areas as a replacement for quick excursions and round trips to get to or from transportation services (e.g., Offices, Institutions, Hospitals, Tourist spots, etc.). This research examines the critical role that micromobility plays, concentrating on the effectiveness of micromobility smart electric scooters in resolving urgent urban problems. Micromobility, which includes both human and electric-powered vehicles, presents a viable substitute for normal and short-distance urban commuting. This study presents a micromobility smart electric scooter that is portable and easy to operate, with the goal of transforming urban transportation. 3D model was designed using SOLIDWORKS and analyzed using ANSYS. For strength and lighter weight aluminium 6061 T6 alloy was used, the design also showcases collapsible seat integration and foldable handle. MATLAB Simulink was used to size the motor, battery and simulate the powertrain system. This scooter has a 500W hub motor and a 48V 20Ah Li-Ion Battery which makes commuting easy while taking into account issues like economic feasibility and environmental sustainability. The vehicle has a range between 26-30 km and maximum speed of 20 kmph. An MIT App Inventor application with Bluetooth connectivity is used to switch the powertrain using smart phone via connecting the vehicle through Bluetooth. By encouraging the use of these cutting-edge automobiles, communities may lessen traffic problems and create a more sustainable and livable urban environment.</div></div>
Cracking and aromatization reaction of n-heptane was carried out on ZSM-5 modified by three methods: They are (i) Extra framework alumina obtained by steaming at high temperature, (ii) Altering the pore size by coke deposition as a function of time on stream, and (iii) Presence of amorphous material in the zeolite. The effect of these modifications on the shape selective product p-xylene is investigated. In all the cases the shape selective properties are profoundly influenced. The presence of extra framework alumina, and coke increased the concentration of para xylene in the product. In the case of ZSM-5 containing amorphous material obtained by synthesizing the zeolite without the aid of template, the para xylene in the product was higher than that obtained over zeolite synthesized using the template. In all the cases the increase in shape selective product may be resulted by decrease in channel dimensions due to the presence of the extraneous materials in the channel. Pore size distribution studies on deactivated catalyst provided evidence for the operation of molecular traffic control (MTC) mechanism in the case of n-heptane aromatiztion reaction.
