Journal ArticleDOI
The attachment of Fe3O4 nanoparticles to graphene oxide by covalent bonding
TL;DR: In this paper, a two-step process was used to construct a hybrid of graphene oxide nanosheets and surface modified Fe 3 O 4 nanoparticles (NPs) using tetraethyl orthosilicate and triethoxysilane to introduce amino groups on its surface.
Journal ArticleDOI
Integrated process planning and scheduling by an agent-based ant colony optimization
TL;DR: The experimental results indicate that the ACO algorithm can effectively solve the IPPS problems and the agent-based implementation can provide a distributive computation of the algorithm.
Journal ArticleDOI
Charge accumulation induced S-shape J–V curves in bilayer heterojunction organic solar cells
TL;DR: In this paper, the S-shape effect in the currentvoltage curve of bilayer heterojunction organic solar cells induced by the EBL was investigated and the authors showed that by gradually increasing the BCP thickness, the J-V curves change from exponential shape to S shape, leading to a twofold degraded in the fill factor.
Journal ArticleDOI
Combustion, performance, regulated and unregulated emissions of a diesel engine with hydrogen addition
TL;DR: In this paper, an experimental investigation was conducted on the combustion, performance, regulated and unregulated emissions of a diesel engine with naturally aspirated hydrogen at the engine speed of 1800 rev −1 under five engine loads.
