“…Both S7 and S8 showed strong EMW attenuation capability in the high frequency range (12)(13)(14)(15)(16)(17)(18), while S6 exhibited a weak performance in the whole tested range (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18). It is obviously that S7 possessed the best attenuation capability compared to the other samples, which was beneficial to enhance EM wave energy attenuation.…”

“…Therefore, there is a great demand for developing broadband and high-efficiency electromagnetic wave (EMW) absorbing materials to minimize adverse effects in aspects of health and electrical devices [1][2][3]. Abundant efforts have been contributed to the development of high-efficiency EMW absorbers with a broad effective absorption bandwidth (EAB), especially for the radar frequency range of 2-18 GHz [4][5][6]. In general, materials with laminated structure are well known as promising EMW absorbers.…”

Electromagnetic pollution has been causing a series of problems in people's life, and electromagnetic absorbers with lightweight and broad absorbing bandwidth properties are widely desired. In this work, novel sandwich-like 2D laminated Fe&TiO 2 nanoparticles@C nanocomposites were rationally designed and successfully developed from the MXene-MOFs hybrids. The formation of Fe and rutile-TiO 2 nanoparticles sandwiched by the two-dimensional carbon nanosheets provided strong electromagnetic energy attenuation and good impedance matching for electromagnetic wave (EMW) absorption. As expected, the nanocomposites achieved a broad effective absorption bandwidth of 6.5 GHz at a thickness of only 1.6 mm and the minimum reflection loss (RL) value of − 51.8 dB at 6.6 GHz with a thickness of 3 mm. This work not only provides a good design and fabricating concept for the laminated metal and functional nanoparticles@C nanocomposites with good EMW absorption, but also offers an important guideline to fabricate various two-dimensional nanocomposites derived from the MXene precursors.

“…A simple hydrothermal procedure (100°C, 6 h, presence of NH 3 ) can produce quantum dots (QDs) with the size of (4.2 � 0.6) nm with subsequent application of QDs for fluorescent detection of alkaline phosphatase activity assay and for embryonic stem cell identification [37]. Another hydrothermal method (150°C, 5 h; ascorbate and Fe 3 + salt) was applied to prepare MXene modified by small magnetic particles with the size of 4.9 nm [38]. Such hybrid magnetic nanoparticles have a great potential to be applied for selective enrichment of various biomolecules based on affinity interactions.…”

MXenes are a new group of 2D nanomaterials with fascinating properties including high electrical conductivity, hydrophilic nature, easily tunable structure and high surface area. This is why MXene modified interfaces are extremely promising for the preparation of sensitive electrochemical biosensors. While there are numerous reports on MXene‐based enzymatic biosensors for detection of a wide range of analytes, application of MXene for construction of affinity biosensors is in its infancy. The review article summarizes current state‐of the‐art in the field with a focus on MXene modifications needed for construction of robust and high performance MXene electrochemical biosensors.

“…MXene has been particularly noted by the scientific community in the last 8 years for its unique structure and electrical properties [12][13][14]. MXene's utilization for microwave absorption is increasing day by day; however, the understanding of its contribution is only related to its metal-like properties and surface-rich functional groups [1,[11][12][13][14][15][16][17][18]. In addition, the graphene-like two-dimensional materials with a multi-layer feature, MXene has a high dielectric loss in a polymer matrix at low percolation limit (15 wt%) [12].…”

Enhancement of microwave absorption bandwidth of MXene nanocomposites through macroscopic design

MXene, the new family of two-dimensional materials having numerous nanoscale layers, is being considered as a novel microwave absorption material. However, MXene/functionalized MXene-loaded polymer nanocomposites exhibit narrow reflection loss (RL) bandwidth (RL less than or equal to −10 dB). In order to enhance the microwave absorption bandwidth of MXene hybrid-matrix materials, for the first time, macroscopic design approach is carried out for TiO 2 -Ti 3 C 2 T x MXene and Fe 3 O 4 @TiO 2 -Ti 3 C 2 T x MXene hybrids through simulation. The simulated results indicate that use of pyramidal meta structure of MXene can significantly tune the RL bandwidth. For optimized MXene hybrid-matrix materials pyramid pattern, the bandwidth enhances to 3–18 GHz. Experimental RL value well matched with the simulated RL. On the other hand, the optimized Fe 3 O 4 @TiO 2 -Ti 3 C 2 T x hybrid exhibits two specific absorption bandwidths (minimum RL value - −47 dB). Compared with other two-dimensional nanocomposites such as graphene or Fe 3 O 4 -graphene, MXene hybrid-matrix materials show better microwave absorption bandwidth in macroscopic pattern.
