Breakthrough progress! Ti3C2Tx new application
Studies have shown that single-layer Ti3C2Tx nanosheets have a light transmittance of about 97% in the visible region, and have metal conductivity and hydrophilicity, and can be stably dispersed in the water medium. Therefore, researchers have used single-layer Ti3C2Tx nanosheets to prepare transparent conductive materials, and have made a breakthrough. On February 7, 2023, ACS Nano reported that researchers developed a MXene dispersion solution with a high monolayer ratio, large size and narrow particle size distribution through the three-step method of etching, stripping and g
How did the carbon nanotubes in the top issue of 2023 perform
Carbon nanotubes, as one of the most representative materials in carbon nanomaterials, have been intensively studied for more than 30 years, and countless results have been achieved, and a number of excellent works have emerged in the top journal of 2023. On January 26, 2023, Nature Energy reported the application of CNT yarns in mechanical energy collectors. The device uses stretching to make the capacitance of the capacitor change, causing a current in the circuit, which converts mechanical energy into electrical energy. The researchers prepared the twisted yarn of CNT by modi
MXenes(two-dimensional (2D) transition metal (TM) carbides (TMCs), TM nitride (TMNs) and TM Carbon nitride (TMCNs) are the largest family of two-dimensional materials (2DMs) in the future, with novel applications in different nanotechnology research at the academic and industrial levels. MXenes nanomaterials have the potential to be classified as "wonder materials" for two-dimensional nanomaterials (NMs). Since its first discovery in 2011, MXenes have been studied and synthesized for more than a decade, with more than 50 members conducting experimental studies and more than 100 members c

You can lubricate bicycle chains with oil, but what about hot conveyor belts in the steel industry or on Mars rovers? The Vienna University of Technology has now studied very special nanomaterials together with research groups from Saarbrucken (Germany), Purdue University in the United States and the University of Chile (Santiago, Chile). In recent years, MXenes' material category (pronounced "maxene") has caused a stir in connection with new battery technologies. But now they are also proving to be an excellent solid lubricant, extremely durable and capabl
MXene is a new two-dimensional material with a wide range of downstream applications after 2022
MXene is a two-dimensional material, which is a kind of transition metal carbide, transition metal nitride or transition metal carbonitride with two-dimensional layered structure. It is a new material obtained by MAX phase treatment and has a structure similar to graphene. MXene was discovered in 2011 at Drexel University in the United States, where it was first discovered as a transition metal carbide with good electrical conductivity. MXene can be prepared by etching the MAX phase with an etching solution containing fluorine, such as hydrofluoric acid, etc. There are many kinds of MAX phase

Ultra-high-rate pseudocapacitive energy storage in two-dimensional transition metal carbides
(Nature Energy, 2017,DOI:10.1038/nenergy.2017.105) Two-dimensional transition metal carbides (MXenes) can provide higher volume and area capacitance than carbon, conductive polymers or transition metal oxides at sweeping speeds beyond those of conventional double-layer capacitors. The researchers confirmed that different electrode design strategies affect the capacitance of Mxene close to the theoretical voltage window, and also showed that the extended voltage window can be obtained not only in glassy carbon, but also in other fluid collector applications.
