Electrochemical upgrading of bio-oil: Effect of acetic acid and aromatic-rich fraction on coke formation

能源环境保护
Bio-oil is the only liquid carbon-containing renewable resource. Due to its complex composition, low calorific value, high acidity, high viscosity, and other factors, it requires upgrading before further utilization. Electrochemical upgrading is a novel,

Flame Speciation and Laminar Burning Velocity of Tetralin Flames Under Atmospheric Pressure

Energies
We present a combined experimental and modeling study of premixed atmospheric-pressure tetralin flames. Chemical speciation in near-stoichiometric (φ = 0.8–1.0) tetralin/O2/Ar flames was characterized by probe-sampling molecular-beam mass spectrometry ...

Selective Electrochemical Leaching of Copper from Fragmented Waste Printed Circuit Boards in an Alkaline Sulfate–Glycine Electrolyte

Metals
Waste printed circuit boards (WPCBs) are a highly concentrated secondary source of copper. However, their complex and heterogeneous composition significantly complicates the selective extraction of metals.

A Low-Cost IoT Sensor and Preliminary Machine-Learning Feasibility Study for Monitoring In-Cabin Air Quality: A Pilot Case from Almaty

Sensors
The air quality within urban public transport is a critical determinant of passenger health. In the crowded and poorly ventilated cabins of Almaty’s metro, buses, and trolleybuses, concentrations of CO2 and PM2.5 often accumulate, elevating the risk of ...
