Biogas as a sustainable fuel for internal combustion engines: Production, purification, and performance assessment.

This study underscores the urgency of reducing dependence on fossil fuels and transitioning toward cleaner, sustainable energy alternatives. It emphasizes biogas as a viable and eco-friendly substitute for conventional fuels, assessing its potential for application in internal combustion engines (ICEs). The investigation covers the key attributes of biogas, including its production methods, chemical makeup, purification requirements, and the necessary engine adaptations to enable its efficient use in ICEs.

Performance assessment of solar PV panels under varying environmental conditions: a laboratory and field-based approach for sustainable energy in mining operations.

This study provides a novel and comprehensive assessment of solar photovoltaic (PV) panel performance under varying environmental conditions, integrating laboratory experiments with real-world field studies to address challenges specific to mining operations. The research uniquely explores the combined effects of shading, temperature, humidity, dust deposition, and tilt angle, delivering actionable insights for optimizing PV systems in harsh conditions. Laboratory experiments demonstrated that a parallel configuration significantly minimizes power losses under partial shading, while a rise in temperature from 35 to 75 °C resulted in a notable 21.

Optimization of two-wheeler Bike engine among three different designs using design of experiments.

This research presents the results of a fin heat transfer study of three different models of the motorcycle engine. The objective of this study is to minimize the external body temperature because the optimum design will be found when the heat transfer rate is maximized. The study obtains the procurement of a balance between the outer boundary temperature due to convective heat transfer and air-cooled fin design.

Bibliometric analysis, physical properties, and experimental evaluation of additives-diesel ternary blends.

The availability of petroleum fuels is being challenged due to high demand and heavy dependence on imports, raising awareness of the need for cleaner alternatives. Urbanization, air quality, economic factors, and emissions limits motivate the search for alternative fuels compatible with compression ignition engines. A comprehensive bibliometric analysis further underscores the escalating worldwide research efforts in this critical domain.

A graphene-based material for green sustainable energy technology for hydrogen storage.

The usage of graphene-based materials (GMs) as energy storage is incredibly popular. Significant obstacles now exist in the way of the generation, storage and consumption of sustainable energy. A primary focus in the work being done to advance environmentally friendly energy technology is the development of effective energy storage materials.

Segmentation of OECD countries on the basis of selected global environmental indicators using k-means non-hierarchical clustering.

In order to allocate resources and describe progress, frequently nations are grouped together by many international authorities. A variety of pertinent indicators can provide a more useful basis for classification for each specific area of interest. Based on commonalities between various variables connected to the global environmental sector, we developed a novel typology of country clusters.

Cow-urine emulsified diesel fuel: preparation, stability, and rheological study for diesel engine application.

Water-diesel emulsion fuel has been found as a prominent alternative fuel by various researchers. Alike this technology, cow-urine (Bos indicus urine) emulsified diesel fuel (GMD emulsion) has been explored in this study. Making of homogeneous and stable emulsion is a crucial aspect in this approach while maintaining the diesel standards.

Synthesis of water, sanitation, and hygiene (WaSH) spatial pattern in rural India: an integrated interpretation of WaSH practices.

Rural areas largely lack access to improved drinking water, sanitation, and hygiene (WaSH) facilities in India. This requires documentation of WaSH practices at the local level for better understanding and sustainable development. In this paper, a global positioning system (GPS)-based household survey was carried out in 67 villages of Phagi tehsil using individual questionnaires to evaluate the existing WaSH conditions spatially at the panchayat level.

Study of thermal comfort in the residents of different climatic regions of India-Effect of the COVID-19 lockdown.

Thermal comfort standards are essential to ensure comfortable and enjoyable indoor conditions, and they also help in optimizing energy use. Thermal comfort studies, either climate chamber-based or field investigation, are conducted across the globe in order to ascertain the comfort limits as per the climatic and other adaptive features. However, very few studies are conducted when the occupants are subjected to a stressed condition, like the COVID-19 lockdown, which may not only have the health impacts but also have psychological impacts on the adaptation.

Economic and environmental impact analyses of hybrid generation system in respect to Rajasthan.

This paper intends to show the aspects of an environment-friendly hybrid energy system (HES) for reducing the electrical power problems in remote areas and providing pollution-free energy. It draws attention towards renewable HES to attain a consistent and independent system. Optimization of the apparatus extent, step-up asset price, and effects on environment is also taken care of.
