This product contains Nb2C flakes solution in ethanol (or other) media. Other solutions are also available please drop a note during the checkout process about your desired solution. The Nb2C solution has been developed by pulsed ultrasonic treatment of high quality Nb2C crystals synthesized through microwave reactor and acid treatment technique to achieve high quality Nb2C sheets dispersed in solution. The crystallinity of Nb2C flakes has been confirmed through electron energy dispersive spectroscopy (EDAX), Raman spectroscopy (FWHM<5 cm-1), and scanning electron microscopy (SEM) measurements. Lateral sizes of Nb2C flakes deposited onto different substrates range from ~10nm to ~5 micrometers while thickness range from 1L to few and multilayers.
Note on volume, concentration, and solvent type: International shipping mostly allows only small volume shipping, thus we ship supersaturated 2D solutions (~100-300 mg/L depending on the type of 2D layers). These supersaturated solutions are designed specifically so that you can dilute to produce large volume (250-500mL) solutions. In our product, ethanol is used (and recommended) as the dispersant solvent owing to its environmental stability, thermal stability, dispersant properties, and non-contaminating nature. However, if your research needs other solvents, either contact us or drop a note during the check out process regarding your desired solution type.
