2D Superparamagnetic Tantalum Carbide Composite MXenes for Efficient Breast-Cancer Theranostics
Background: The emergence of two-dimensional MXenes has spurred their versatile applications in broad fields, but the exploring of novel MXene-based family members and their potential applications in theranostic nanomedicine (concurrent diagnostic imaging and therapy) have been rarely explored. In this work, we report the construction of a novel superparamagnetic MXene-based theranostic nanopla...
متن کاملLithium-ion capacitors with 2D Nb2CTx (MXene) - carbon nanotube electrodes
3 types of lithium-ion capacitors using Nb2CTx-CNT as one electrode were tested. The highest volumetric energy density of 50e70 Wh/L was achieved. Energy density of symmetric cell exceeds that of lithium titanate/acti-
متن کاملTantalum Carbide and Nitride Diffusion Barriers for Cu Metallisation
The reactions in the Si/TaC/Cu and Si/Ta2N/Cu metallisation systems were investigated by x-ray diffraction, Rutherford backscattering, scanning electron microscope and the transmission electron microscopy. The results were then combined with the assessed ternary SiTa-C, Ta-C-Cu, Si-Ta-N and Ta-N-Cu phase diagrams. It was found that both barriers ultimately failed due to diffusion of Cu through ...
متن کاملThermal Analysis of Tantalum Carbide-Hafnium Carbide Solid Solutions from Room Temperature to 1400 C
The thermogravimetric analysis on TaC, HfC, and their solid solutions has been carried out in air up to 1400 ◦C. Three solid solution compositions have been chosen: 80TaC-20 vol % HfC (T80H20), 50TaC-50 vol % HfC (T50H50), and 20TaC-80 vol % HfC (T20H80), in addition to pure TaC and HfC. Solid solutions exhibit better oxidation resistance than the pure carbides. The onset of oxidation is delaye...
متن کاملTwo-Dimensional Vanadium Carbide (MXene) as Positive Electrode for Sodium-Ion Capacitors.
Ion capacitors store energy through intercalation of cations into an electrode at a faster rate than in batteries and within a larger potential window. These devices reach a higher energy density compared to electrochemical double layer capacitor. Li-ion capacitors are already produced commercially, but the development of Na-ion capacitors is hindered by lack of materials that would allow fast ...
