The main target of the current research work is effectively eliminating fossil fuel dependency and improving exhaust air quality conventional Compression Ignition (CI) engines. This paper demonstrates for first time that a nanofluid (water without surfactant) stored in separate tanks can be quantified, collected, immediately emulsified by high shear mixer before transfer into combustion chamber...

There continues to be significant interest in the development, certification, and use of alternative (non-petroleum) aviation fuels. The motivation for this is driven by many factors, including the growing demand and reduced supply of petroleum-derived fuels, cost volatility, and desire for a reliable domestic fuel supply. In addition, the production of alternative fuels from renewable/biologic...

Furfural is one of the most promising chemical platforms with bright perspective with respect to the production of biobased chemicals and fuels from lignocellulosic material. Globally, the majority of this biomass derived chemical is converted into furfuryl alcohol, a building block in polymers industry. The vapor-phase hydrogenation of furfural over copper species dispersed on two types of sil...

This study focused on evaluating the lubricity of diesel–biodiesel fuel with oxygenated alcoholic and nano-particle additives. Fuel injection system lubrication depended primarily used in diesel engine. Palm–sesame oil blend was to produce biodiesel using ultrasound-assisted technique. B30 sample as a base blended additives different proportions prior tribological behavior analysis. The samples...

BACKGROUND India contributes 24% of the global annual child deaths due to acute respiratory infections (ARIs). According to WHO, nearly 50% of the deaths among children due to ARIs is because of indoor air pollution (IAP). There is insufficient evidence on the relationship between IAP from the use of solid fuels and incidence of life threatening respiratory illnesses (LTRI) in children in India...

Priester et al. (1) recently investigated the growth of soybean in soil amended with ZnO and CeO2 manufactured nanomaterials (MNMs). It is laudable that the study used soil: Too few studies to date do this. However, we question the agronomic and environmental relevance of this study because of a lack of control experiments with a soluble salt (for ZnO) and with larger-scale particles (for ZnO o...

Fossil fuels in the transport and mobility sector can be replaced with several renewable fuels, such as renewable electricity, hydrogen and biomass-to-liquid. When these alternative fuels are used, aspects such as safeguarding supply, economic efficiency, and environmental protection must be taken into account to ensure sustainable change and to create a sustainable society. We introduce a scen...
