The availability of natural soils with hydraulic conductivity below 1 × 10−9m/sfor liner systems is declining, while industrial waste such as circulating fluidized bed combustion (CFBC) fly ash remains underutilized...

The authors performed minimum burning pressure (MBP) test on ammonium nitrate emulsions (ANEs) to validate the test procedure for incorporating the United Nations (UN) 8(e) test into the Japanese Industrial Standards. AN...

Studying the organoleptic properties of heated tobaccos in relation to natural flavors is essential for understanding how lower-temperature processing influences the release of intrinsic tobacco flavor compounds. Unlike ...

The aim of this work was to create and study of ferrite nickel-cobalt powders, using sol-gel technology withparticipation of auto-combustion. After completing the process autocombustion was obtained only one phase,which ...

The objectives of the current study are to assess the performance and emission characteristics of a diesel engine running on Juliflora biodiesel-based blends at varying levels of brake power. These ob-jectives were achie...

Eco-friendly approaches for nanoparticle synthesis have gained attention due to their sustainability and reduced environmental impact. Zinc oxide nanoparticles (ZnO NPs) exhibit versatile bioactivities, but conventional ...

The objective of this study is to enhance the energy efficiency and environmental safety of boiler plants and engines equipped with waste heat recovery boilers. This objective is achieved by utilizing water-fuel emulsion...

To investigate the influence of cracks and gaps on the reaction evolution characteristics of aluminum-containing DNAN-based explosives after the formation of mechanical induced hotspots, explosive charge samples with dif...

The conversion of tea twig biomass into porous activated carbon presents a sustainable pathway for mitigating CO2 emissions. This study systematically compares two thermo-chemical synthesis routes, activation-carbonizati...

The depletion of non-renewable fossil energy reserves is the main reason for this research to develop renewable energy as a substitute for diesel fuel. One of the alternatives studied is the production of biodiesel from ...

With the increasingly stringent environmental regulations on road traffic, the emission standards for particulate matter from internal combustion engines have risen significantly. Consequently, the implementation of part...

This study investigates two NOx-mitigation strategies, namely exhaust gas recirculation (EGR) and water–diesel emulsification, in a diesel–hydrogen dual-fuel compression ignition engine. A validated three-dimensional...

Industrial and agricultural activities as well as the combustion of fossil fuels lead to increased levels of sulphur (S) deposition in terrestrial and aquatic ecosystems, affecting soil acidity and plant communities. Loc...

In this paper, the synthesis of spinel magnesium ferrite (MgFe2O4) nanoparticles is reported, along with its structural, magnetic and hyperthermic properties, which ensure them being effectively used in various fields. F...

Combustion of aluminized solid propellants exhibits phenomena associated with accumulation, agglomeration, ignition, and combustion of ultra-fine aluminium particles. In this study, agglomeration phenomenon of ultra-fine...

La adecuada interpretación de los patrones observados en la distribución sexual, etárea y cronológica de los indicadores biológicos considerados en los estudios bioarqueológicos depende, en gran medida, del conocim...

"Reductions of fuel consumption and gas emissions count among the main advantages of hybrid electric vehicles (HEV). It is well known that the level of hybridisation has a large influence on the fuel consumption, the m...

La Fogata de ramitas y huesos de Roxana Páez logra sin duda con maestría y en una demostración de madurez estética, hacer confluir en el hilo delgado de los versos cada cosa y su reverso: por eso, más allá de la pe...

CONTEXT: Associations have been found between day-to-day particulate air pollution and increased risk of various adverse health outcomes, including cardiopulmonary mortality. However, studies of health effects of long-te...

Abstract Polycyclic aromatic compounds (PACs) are known due to their mutagenic activity. Among them, 2-nitrobenzanthrone (2-NBA) and 3-nitrobenzanthrone (3-NBA) are considered as two of the most potent mutagens found in ...

Each cell of a battery stores electrical energy as chemical energy in two electrodes, a reductant (anode) and an oxidant (cathode), separated by an electrolyte that transfers the ionic component of the chemical reaction ...
