In this paper, we proposed a facile one-step strategy to prepare graphene-Fe3O4 (GN–Fe3O4) nanocomposites under hydrothermal conditions, where the reduction process of graphite oxide (GO) sheets into GN was accompanied by generation Fe3O4 nanoparticles. The extent GO could be comparable that conventional methods. A transmission electron microscopy image has shown as-formed nanoparticles with diameter as small 7 nm were densely and uniformly deposited on sheets, and, result, aggregating...

Lanthanide organic frameworks (Ln-MOFs) have attracted increasing research enthusiasm as photoluminescent materials. However, limited luminescence efficiency stemming from restricted energy transfer the linker to metal center hinders their applications. Herein, a uranyl sensitization approach was proposed boost of Ln-MOFs in distinct heterobimetallic uranyl-europium framework.

Developing a better understanding of covalency (or orbital mixing) is fundamental importance. Covalency occupies central role in directing chemical and physical properties for almost any given compound or material. Hence, the concept has potential to generate broad substantial scientific advances, ranging from biological applications condensed matter physics. Given importance mixing combined with difficultly measuring covalency, estimating inferring often leads fiery debate. Consider 60-year...
