Aseptic beverage cartons are multilayer polymer-coated paperboards with a layer of aluminum foil. Due to their structure it is commonly assumed that they cannot be recycled. This not the case and this review details multifarious processes used recycle aseptic cartons. Hydrapulping recover paper fibers constitute 75% carton most widespread process, followed by manufacture construction materials ...

Abstract Aluminum is an attractive candidate for replacing graphite anodes in lithium‐ion batteries because of its high specific capacity and the potential direct use as foil. However, achieving reversible reaction aluminum challenging due to volume changes, SEI formation, sluggish ion transport. Although prior work has investigated electrochemical transformation behavior aluminum, effects key ...

Submicron-sized airborne particulate matter (PM) is not collected well on regular quartz or glass fiber filter papers. We used a micro-orifice uniform deposit impactor (MOUDI) to fractionate PM into 6 size fractions and deposit it on specially designed high-purity thin aluminum disks. The MOUDI separated PM into fractions 56–100, 100–180, 180–320, 320–560, 560–1000, and 1000–1800 nm. Since the ...

The present study aims at developing A356/Al2O3(np) nano-composite with a novel and cost effective method for attaining homogeneous dispersion of Al2O3 nanoparticles in the Al matrix. In the current research, Al micro powders distributed on aluminum foil and then Al2O3 nanoparticles ultra-sounded in ethanol and sprayed on Al substrate. Subsequently, the sandwich foil was added to molten A356 du...
