Recent Progress in Carbon Fiber Reinforced Polymers Recycling: A Review of Recycling Methods and Reuse of Carbon Fibers [PDF]

Materials, 2021
The rapid increase in the application of carbon fiber reinforced polymer (CFRP) composite materials represents a challenge to waste recycling. The circular economy approach coupled with the possibility of recovering carbon fibers from CFRP waste with similar properties to virgin carbon fibers at a much lower cost and with lower energy consumption ...

Composite Laminates with Recycled Carbon Fibres and Carbon Nanotubes [PDF]

Materiale Plastice, 2020
Carbon fibre reinforced composites were manufactured by using recycled carbon fibres (CF) and carbon nanotubes (CNT). Dry fabrics were impregnated by hot melting with 1 wt% CNT filled epoxy resin to produce prepregs. Subsequently, composite laminates were manufactured by vacuum bagging and autoclave moulding.

Carbon Fiber/PLA Recycled Composite

Polymers, 2022
Due exceptional properties such as its high-temperature resistance, mechanical characteristics, and relatively lower price, the demand for carbon fiber has been increasing over the past years. The widespread use of carbon-fiber-reinforced polymers or plastics (CFRP) has attracted many industries.

Magnetically Recyclable Catalytic Carbon Nanoreactors [PDF]

Advanced Functional Materials, 2018
AbstractMultifunctional nanoreactors are assembled using hollow graphitized carbon nanofibers (GNFs) combined with nanocatalysts (Pd or Pt) and magnetic nanoparticles. The latter are introduced in the form of carbon‐coated cobalt nanomagnets (Co@Cn) adsorbed on GNF, or formed directly on GNF from ferrocene yielding carbon‐coated iron nanomagnets (Fe@Cn)

Probing recycled carbonate in the lower mantle

National Science Review, 2022
Whether surficial carbonates can be carried into the Earth's lower mantle is key to global deep carbon cycles but remains poorly understood. New clues from magnesium and zinc isotopic systematics on rocks from deep-rooted mantle plumes are presented and discussed in this Perspective.

Solid Oxide Fuel Cell with Anodes using Proton Conductor (Barium-Cerium/Yttrium Oxide)

Journal of Thermal Science and Technology, 2009
A new anode with a proton conductor (Barium-Cerium/Yttrium oxide (BCY): BaCe0.8Y0.2O3-δ) was proposed for a high-power, solid-oxide fuel cell. In the new anode, the proton-conducting material was included in a conventional anode made of nickel (Ni)

FDTD Simulation of Near-Field Radiative Heat Transfer between Thin Films Supporting Surface Phonon Polaritons: Lessons Learned

Journal of Thermal Science and Technology, 2013
We present the numerical simulation, using the finite difference time domain (FDTD) method, of the radiative heat transfer between two thin SiC slabs. We aim to explore the ability of the FDTD method to reproduce the analytical results for the Surface ...

Carbon dioxide recycling [PDF]

Clean Technologies and Environmental Policy, 2009
The recycling of carbon dioxide to methanol and dimethyl ether is seen to offer a substantial route to renewable and environmentally carbon neutral fuels. One of the authors has championed the ‘‘Methanol Economy’’ in articles and a book. By recycling ambient CO2, the authors argue that we do not contribute new GHG to the atmosphere but remove a ...
