TL;DR: This work clearly indicated that carbon-based nanomaterials are toxic while the hazardous effect is size-dependent, and cytotoxicity is enhanced when the surface of the particles is functionalized after an acid treatment.

TL;DR: In this article, the uniaxial strain and pressure derivatives of T c were analyzed for thin films of copper oxide superconductors, and it was shown that compressive epitaxial strain could in principle generate much larger increases in the critical temperature than obtained by comparable hydrostatic pressures.

TL;DR: P polarization-dependent X-ray magnetic dichroism spectro-microscopy is presented that reveals the micromagnetic structure on both sides of a ferromagnetic–antiferromagnetic interface, implying that the alignment of the ferrom magnetic spins is determined, domain by domain, by the spin directions in the underlying antiferromagnet layer.

TL;DR: These studies open the door for a microscopic understanding of the magnetic coupling across antiferromagnetic-ferromagnetic interfaces.

TL;DR: In this article, multiwalled carbon nanotubes (MWCNTs) were synthesized in a catalytic reaction using CaCO3 as catalyst support, which enabled the production of MWCNTs in a fixed-bed flow reactor at relatively low reaction temperature.
