Environmental concerns push for a reduction in greenhouse gas emissions and technologies with low carbon footprint. In the transportation sector, this drives transition toward electric vehicles (EVs), which are nowadays mainly based on lithium-ion batteries (LIBs). As number of produced EVs is rapidly growing, large amount waste expected future. Recycling seems to be one most promising end-of-life (EOL) methods; it reduces raw material consumption battery production environmental burden....
Pyrolysis represents one of the most convenient technologies for chemical transformation waste. The exposure to corrosion products and high temperatures does, however, require chemically resistant construction materials. This study was carried out analyze behavior 1.4571 (AISI 316Ti) 1.4305 303) stainless steels machined with wire electric discharge machining (WEDM) in a pyrolysis environment. Different parameters were used both materials tested examine influence WEDM machining. total...
Occurrence, distribution, and toxicity assessment of 16 Polycyclic Aromatic Hydrocarbons (PAHs) prioritized by the US Environmental Protection Agency in pyrolysis products -pyrolysis oil wax -of different plastics are characterized.PP, HDPE, LDPE, PVC, PS (respectively, polypropylene, high-and low-density polyethylene, polyvinylchloride polystyrene) their mixture named 5P chosen as a feed material for pyrolysis.Pyrolysis process is carried out custom-built laboratory batch reactor with...
Lithium is crucial in lithium-ion batteries (LIBs), serving as a main component of the electrolyte and cathode. Elements such cobalt, nickel, manganese are also vital for high performance, energy density, stability. This study aimed to examine behaviour end-of-life cathode material (NMC622) its valuable metals after exposure temperatures between 100 400 °C, comparing it with untreated material. The lithium content cannot be reliably determined by conventional analytical methods, so...
An intermetallic layer (IML) between the solder alloy and soldered surface affects mechanical electrical performance of resulting joints. Numerous studies have explored possibilities influencing IML to achieve more reliable interconnections. However, type composition used flux, crucial for proper creation joints, is rarely included as a possible factor. In this article, comprehensive study on interfacial microstructure evolution lead‐free SnAgCu accounting flux temperature preheating phase...
The popularity of lithium-ion batteries (LIBs) as crucial power sources has increased in recent years. LIBs represent a perspective technology for recycling because they comprise high portion valuable metals, such nickel, manganese, cobalt, or lithium, and other including aluminium, copper, iron. Battery discharging represents an essential step end-of-life (EOL) pretreatment, it reduces the risk fire explosion further processing. As simple, quick, inexpensive technique, electrochemical...
Ethylenediaminetetraacetic acid (EDTA) has increasing potential as an environmentally hazardous material. Although EDTA exhibits relatively low acute toxicity, it been found to be cytotoxic and weakly genotoxic in laboratory animals. In addition, oral exposures can cause reproductive developmental effects. is commonly used wood industry, pulp paper textile cement industry food industry. It also widely laundry applications order reduce the water hardness many cleaning solutions.
3D printing is an extensively used manufacturing technique that can pose specific health concerns due to the emission of volatile organic compounds (VOC). Herein, a detailed characterization printing-related VOC using solid-phase microextraction-gas chromatography/mass spectrometry (SPME-GC/MS) described for first time. The were extracted in dynamic mode during from acrylonitrile-styrene-acrylate filament environmental chamber. effect extraction time on efficiency 16 main was studied four...
Magnetic sorbents have great potential in environmental applications due to their simple synthesis and separation magnetic field, usability heterogeneous systems low toxicity. Possible syntheses, surface modifications characteristics were described by Li et al 2013. This type of solid-phase extraction is being successfully used various fields as health care, microbiology, biotechnologies or sample preconcentration analytical chemistry. In this preliminary study we report on the preparation...
