Evaluating the Environmental Footprint of Electric Vehicles: A Life Cycle Assessment Approach for Sustainable Mobility in India2026-26-0235To be published on 01/16/2026
Road transport contributes 12% of India's energy-related CO2 emissions and is a major source of urban air pollution. These emissions have tripled since 1990, driven by rapid urbanization and the growing demand for private vehicles. Without a shift away from fossil fuels, these trends will intensify climate and air quality challenges. Among sustainable alternatives, electric vehicles (EVs) have emerged as a promising solution. However, a comprehensive understanding of their environmental performance, particularly in the Indian context, is essential for informed decision-making. This study employs a Cradle-to-Grave Life Cycle Assessment (LCA) to evaluate the environmental impacts of typical passenger vehicle with a ICE engine compared to its EV powertrain. Key life cycle stages-manufacturing, transportation, distribution, maintenance, and end-of-life-are analysed using real-world data wherever feasible. To capture the evolving energy landscape, the study incorporates India's projected

Performance Analysis of High gain DC-DC Converter for Solar PV Applications2022-28-049511/18/2022
The conventional energy resources continue to experience a depleting trend particularly with the growing energy demand to support the ongoing automation phase in the industries. Besides the other challenges include environmental issues in the form of global warming and increasing concerns of pollution to the atmosphere. It invites attention to exploring the use of renewable sources and among the many options Solar PV systems draw a greater attention. However, the non-linear nature of the I-V characteristic of the solar cell allows the delivery of the maximum power only at a specific point called Maximum Power Point, which depends on the solar irradiance, cell temperature and load conditions. The immediate requirement relates to improving the efficiency of the Solar PV system and therefore the focus orients to introduce a high gain DC-DC converter interface between the Solar PV and the load, with a purpose to envisage the transfer of power at a high efficiency.

Energy Scavenging from Passengers for Powering Low-energy Electronics in Aircrafts2022-26-125505/26/2022
With the ever increasing demand for aerial modes of transportation and reduction of different harmful emissions from these modes of transportation has led to demand for more electric modes of powering these aerial vehicles. In addition to that, the aerospace industry is also looking to make the aircrafts more smart and more connected. This involves increased use of more sensors, ICs and many more micro-electronic components. Even though they look small and consume less electricity, the electric battery which is supposed to be used for aircraft propulsion will require to power up these smaller components as well, which will continue to be a concern as the aircrafts begin using more and more of these components. Hence, a solution is needed to reduce the dependency of micro-electronic components or any other aircraft components used within the aircraft on the electric battery to be used for aircraft propulsion. The concept of Energy Harvesting or Energy Scavenging refers to the capturing

“Development of Autonomous Solar powered RC Aircraft”2022-26-124605/26/2022
In the present-day world due to causing harm to environment and drastic depression in the availability of the non-renewable sources of energy (I.e., petrol, Diesel, Natural gas etc). It’s crucial for us to find alternative energy sources to suit our needs. One of the types of sources which is least used despite its abundance is solar energy. The reasons like “high cost” and “lack of technology” were substantiated in the past to prove its inefficiency. But, recent development in technology and studies have shown the ways of tapping the solar energy and converting it (E.g., electricity, heat etc.) and utilizing it in various applications. Apparently, there is minimal use of solar energy in aviation and RC aircraft fields. The aviation field uses high amount of white petroleum (highly polluting after combustion) and Batteries which are both harmful and expensive. This can pave way to the advent of solar energy which if properly utilized can act as a game changer by increasing the

Battery Drain Detection and Prevention Mechanism2022-01-086303/29/2022
The purpose of this model is to prevent the draining of car batteries when not used for several weeks. This model comprises of a voltage monitoring sensor, cut off sensor and solar powered car battery charger. The function of the Voltage sensor is to Constantly Measure and monitor the Battery Voltage. The measured value is then sent to cut off sensor as an input. Based on the battery voltage level input from the voltage monitoring sensor, the cut off sensor takes the necessary action. When the voltage of the battery is above the threshold value, the cut off sensor does not take any action. If the voltage of the battery is low, then the cut off sensor cuts off the power supply from the battery and triggers the solar powered car battery charger to charge the battery. Once the battery is completely charged the charging process is stopped to prevent the damage of the battery. This cycle is repeated to maintain the battery voltage and prevent it from draining completely.

SOLAR POWERED INCABIN EVAPORATIVE COOLING SYSTEM2021-28-014409/15/2021
During summer season, Cabin Temperature of car soaked under the Sun, may rise upto 70 Deg C approx. This makes steering and seats inside the car very hot. At High temperatures hazardous gases are also accumulated inside the cabin. To overcome these problems, the passengers switch ON AC immediately after entering the car, which leads high consumption of fuel. Also doors and windows are to be kept open for some time to throw hot gases out. Also have to wait for getting cooling effect. To eliminate these problems a SOLAR POWERED INCABIN EVAPORATIVE COOLING SYSTEM can be installed in the car. This system uses a solar panel to capture the sunlight and convert the Solar energy into the Electrical energy which is used to recharge the 12V battery, which then gives necessary power for the cooling module which consist of water cooler with fan motor. The cool air is blown inside the car which reduces the temperature in the car cabin. The system is controlled by using a switch device. The

According to research conducted by MarketsandMarkets (Northbrook, IL), the military wearables market is projected to grow from $4.2 billion in 2019 to $6.4 billion by 2025. That's a 7.2% growth from 2019 in six short years. Soldier modernization programs that increase soldier coordination, rising asymmetric warfare, and potential geopolitical conflicts are all factors fueling the growth of this market. As soldier-carry technologies continue to expand in scope, soldier power solutions are becoming a critical operational issue. Without access to adequate power, however, these technologies (that include mobile control, communications, intelligence, reconnaissance, surveillance, etc.) become useless on the battlefield and rapidly degrade capabilities. When without sufficient power, the wearable technologies meant to help soldiers more effectively execute operations can instead put them in harms' way.

Smart Windows Self-Illuminate on Rainy DaysTBMG-3766009/01/2020
Smart windows that automatically change colors depending on the intensity of sunlight are gaining attention as they can reduce energy bills by blocking the sun's visible rays during summer. But what about windows that change colors depending on the humidity outside during the monsoon season or on hot days of summer? Recently, a Korean research team has developed the source technology for smart windows that change colors according to the amount of moisture, without needing electricity. The team successfully developed a variable color filter using a metal-hydrogel-metal resonator structure using chitosan-based hydrogel and combined it with solar cells to make a self-powering humidity sensor.
Electronics Cooling Using Additive ManufacturingTBMG-3765409/01/2020
For decades, researchers have considered the potential for cooling hot electronic devices by blowing on them with high-speed air jets; however, air jet cooling systems are not widely used today. Two of the biggest obstacles that prevent the use of these systems is their complexity and weight. Air jet systems must be made of metal to be able to handle the pressure associated with air jets whose speed can exceed 200 miles per hour. And the air handling system can be complex, with many discrete components that manage the airflow and direct the air onto the hot spots where cooling is required.

Quantifying Autonomous Soaring on a Surveillance and Communications Relay Mission20AERP06_1006/01/2020
Research demonstrates that a surveillance mission is still achievable by unmanned vehicles while performing autonomous soaring. Naval Research Laboratory, Washington, DC Missions for small unmanned aircraft (Group 1 and Group 2) include over-the-hill surveillance and providing airborne communications relay points. Greater endurance is almost universally desired by operators to increase the time spent on-station performing the mission and reduce the number and frequency of takeoffs and landings. Autonomous soaring techniques were first proposed by Wharington and refined by Allen as a method to find convective thermal updrafts and gain altitude energy. While several autonomous soaring algorithms have been implemented on unmanned aircraft and demonstrated significant endurance gains, the technology of autonomous soaring has not yet bridged the gap from research to practical application for a mission.

The family of crystals that can be made just one atom thick includes metals, semiconductors, and insulators.
Organic Material for Printed ElectronicsTBMG-3684605/01/2020
In order to increase the conductivity of polymers — and in this way obtain higher efficiency in organic solar cells, light-emitting diodes, and other bioelectronic applications — researchers previously doped the material with various substances. Typically, this is done by either removing an electron or donating it to the semiconductor material with a dopant molecule, a strategy that increases the number of charges and thereby the conductivity of the material. The process is stable for a while but the material degenerates and the substances used as doping agents can eventually leach out.
