TL;DR: In this paper, a high-resolution transmission electron microscope analysis was performed on a few-layer graphene (FLG) as a reinforcement agent for aluminum matrix composites, showing that the composite strength proportionally increases with the specific surface area on the composite, and the composites containing 0.7 vol% FLG exhibit 440 MPa of tensile strength.

TL;DR: In this article, the authors evaluate the potential of c-Si photovoltaics to reach this goal by developing a bottom-up cost model for C-Si wafer, cell, and module manufacturing, and performing a sensitivity analysis to determine research domains that provide the greatest impact on cost.

TL;DR: In this paper, the reinforcing efficiency of MWNTs in the composites follows the volume fraction rule of discontinuous fibers in the grain size range down to 70nm, which is the same as in this paper.

TL;DR: A scalable and catalyst-free method to deposit stoichiometric molybdenum disulfide (MoS2) films over large areas is reported, with the maximum area limited by the size of the substrate holder.

TL;DR: In this paper, the reinforcing effects of carbon nanotubes (CNTs) are investigated for aluminum matrix composites, and a composite containing 4.5 vol% multiwalled CNTs exhibits a yield strength of 620 MPa and fracture toughness of 61 MPa·mm1/2, the values of which are nearly 15 and seven times higher than those of the corresponding starting aluminum, respectively.
