Upconversion nanoparticles (UCNs) find application in nanomedicine as biolabels to identify cancer cells. In this work, Y2O3: Er3+/ Yb3+ and Gd2O3: Er3+/ Yb3+ systems were fabricated by combustion synthesis (CS) and sol-...

Abstract The paper presents a method of calculating the full load engine characteristics based on the Leiderman–Khlystov relation. Because the values of the coefficients of the discussed function available in literatur...

In this paper, we calculate solvation free energies of several compounds in ionic liquids. These free energies are used to compute properties such as Henry's law constants and activity coefficients, generally required in...

Carbonyl sulfide (COS) is a dangerous gas produced from fossil fuel combustion and petrochemical procedures, so proper adsorbent and sensors are required for removal and detection. In this work, we study by Density Funct...

Aluminium is universal and vital constituent in composite propellants and typically used to improve performance. Aluminum agglomeration takes place on the burning surface of aluminized propellants, which leads to reduced...

Abstract Background Polycyclic aromatic hydrocarbons (PAHs) comprise a group of persistent carcinogenic pollutants whose transfer from air to soil via the atmospheric deposition represents a major chronic exposure pathwa...

Cave 338 is a high-altitude prehistoric site located at 2,235 m a. s.l. in the eastern Pyrenees (Queralbs, Girona, NE Iberian Peninsula). Excavated between 2021 and 2023, the site preserves an exceptional and well-strati...

Electronic cigarette (e-cigarette) use has risen rapidly over the past decade, particularly among adolescents and young adults, driven by perceptions of reduced harm compared with combustible cigarettes. Despite the abse...

This review provides a comprehensive examination of carbon capture (CC) technologies, utilization and their integration with e-fuel production as pivotal factors in determining the greenhouse gas (GHG) mitigation potenti...

The oxidation of diesel soot using K/CeO2 catalysts is studied in this paper. The reaction system involved in the catalytic oxidation of soot is quite complex; therefore, the study of reaction mechanisms is particularly ...

Uno de los gases contaminantescon mayor distribución y concentración enToluca y su área metropolitana es el monóxidode carbono que, al igual que el dióxido deazufre y el dióxido de carbono, es generadoprincipalment...

Abstract Engine tests are both costly and time consuming in developing a new internal combustion engine. Therefore, it is of great importance to predict engine characteristics with high accuracy using artificial intellig...

Why has the EU, despite strong climate regulation, advanced manufacturers, and deep industrial finance, fallen behind China in the electric vehicle (EV) transition? This article challenges explanations that attribute Eur...

Abstract The shift from internal combustion engines to electric powertrains has redefined the noise, vibration, and harshness (NVH) profile of contemporary vehicles. The reduction of engine-generated broadband noise has ...

While chlorinated volatile organic compounds (VOCs) are often considered dioxin precursors, the formation pathways of dioxins during biogas combustion from food waste anaerobic digestion plants remain poorly understood. ...

Electric vehicles are currently the leading solution in the automotive market to reduce greenhouse gas emissions. However, transitioning from traditional internal combustion engines poses many challenges. One of these ch...

In the power plants operation, the combustion process will produce particulate emissions. Particulate emissions themselves are known have a negative impact on health, such as causing respiratory problems. The pattern of ...

In this work by using sol-gel auto-combustion synthesis was synthesized single-phase magnesium-substituted lithium ferrite at different pH reaction medium. The synthesized materials were investigated by X-ray and Mossbau...

The increasing release of greenhouse gases (GHGs), particularly CO2, continues to drive global warming and highlights the need for effective mitigation technologies. In this study, porous nanostructured cellulose acetate...

Limited studies focused on acute effects of PM2.5 components and sources exposure on blood pressure and the potential mediating role of DNA methylation. We conducted a repeated-measurement study design with 4 visits invo...

SUMMARY The economic activities that have been historically identified with Brazilian Amazonia required no inanimate energy. Extraction of forest products was managed with manual labor, so was placer mining. Steam powere...

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...
