TL;DR: In this paper, an approach to fabricate flexible graphene papers using chemical vapor deposition (CVD) derived graphene was presented, where expanded vermiculite was used as a layered template in the CVD process to produce bulk materials containing graphene sheets of the order of hundreds of microns at a gram scale.

TL;DR: In this article, carbon nanotubes (CNTs) were prepared by ethylene decomposition on an Fe/Al2O3 catalyst in a fluidized bed reactor and their gross defects at different growth periods were evaluated by using a combination of SEM, TGA and Raman spectroscopy.

TL;DR: The synthesis method that is developed here can be readily applied to incorporation of other metal/metal oxide nanoparticles into carbon nanotubes and the extent of this confinement-induced electron transfer is temperature dependent.

TL;DR: Graphene-CNT hybrids were synthesized by a one-step chemical vapor deposition process using a mixed catalyst of MgO and Fe/MgO in this article, and they had porous structures with hierarchical pore distributions due to the composition of graphene with CNT network.

TL;DR: In this paper, the authors reported a centrifugation-free and high yield synthesis route for hierarchically nanosized ZSM-5 with a wide Si/Al ratio range by a combination of pre-aging process and steam-assisted conversion method using alkalis-free powder as the ZSM precursor, which not only avoids the energy-intensive centrifugal separation and ion exchange process, but also significantly increases the crystallization efficiency along with a high yield.
