Synthesis and Characterization of 2D Nanocrystals and Thin Films of Transition Metal Carbides (MXenes)

Electronic Supplementary Information One-step synthesis of 2D-layered carbon wrapped transition metal nitrides from transition metal carbides (MXenes) for supercapacitors with ultrahigh cycling stability

The preparation of 2D-layered C@TiN: Ti3C2 MXenes were synthesized via the previous reported paper. Typically, 1 g Ti3AlC2 (purchased from FORSMAN Company, China) was added into 15 mL 40% HF solution. The solution was stirred for 120 h at 40 oC. After the HF etching, the material was centrifuged and washed in deionized water until pH~7. The Ti3C2 MXene was obtained after drying at 50 oC for 12h...

Large-scale delamination of multi-layers transition metal carbides and carbonitrides "MXenes".

Herein we report on a general approach to delaminate multi-layered MXenes using an organic base to induce swelling that in turn weakens the bonds between the MX layers. Simple agitation or mild sonication of the swollen MXene in water resulted in the large-scale delamination of the MXene layers. The delamination method is demonstrated for vanadium carbide and titanium carbonitride MXenes.

Composite Materials for Electromagnetic Interference Shielding

This paper demonstrates that the addition of chemical agents and carbon fibers to cement can greatly enhance the shielding effectiveness of the concrete. In addition to improving the shielding effectiveness, carbon fibers and chemical agents enhance the tensile and flexural strengths significant ly. As both carbon fibers and steel fibers are electrically conductive, both can be added to cement ...
