چکیده
Combination of flexible multifunctional stealth technology properties such as electromagnetic (EM) and infrared (IR) is crucial to the development aerospace, military, electronic fields, but synthesis still has a significant challenge. Herein, we have successfully designed synthesized highly [email protected] lamellae/borate ion (MXCB) sheets with strong high-temperature EM-IR bi-stealth through sequential bridging hydrogen covalent bonds. The resultant MXCB display high conductivity good mechanical features flexibility, stretchability, fatigue resistance, ultrasonic damage. tensile strength 795 MPa. Furthermore, different thicknesses indicate exceptional thermal-camouflage characteristics. This reduces radiation temperature target object (>300°C) 100°C. sheet 3 ?m thickness 6108 S/cm EM interference (EMI) shielding value 39.74 dB. normalized surface-specific EMI SE absolute effectiveness (SSE/t) 39312.78 dB·cm2/g, which remained 99.39% even after 10,000 times repeated folding. These ultrathin can be arranged by vacuum-assisted induction develop sheet.

Atomically Resolved Structural and Chemical Investigation of Single MXene Sheets.
The properties of two-dimensional (2D) materials depend strongly on the chemical and electrochemical activity of their surfaces. MXene, one of the most recent additions to 2D materials, shows great promise as an energy storage material. In the present investigation, the chemical and structural properties of individual Ti3C2 MXene sheets with associated surface groups are investigated at the ato...

متن کاملTetracyanide-bridged divanadium complexes: redox switching between strong antiferromagnetic and strong ferromagnetic coupling.
Reaction of [(Me3tacn)V(CF3SO3)3] (Me3tacn = N,N',N''-trimethyl-1,4,7-triazacyclononane) with LiCN in DMF results in oligomerization of cyanide to form [(Me3tacn)2V2(CN)4(mu-C4N4)]. The structure of this binuclear complex features a planar tetracyanide unit bridging two VIV centers via imido type linkages. The conjugated pathway provided by the bridging ligand leads to strong antiferromagnetic ...
متن کاملLooking for the First Galaxies with Emir/gtc
The new Pop III models by Schaerer (2002) have been used to derive the observed properties of the first galaxies in terms of the expected magnitudes and colors. The dependence of their properties on the IMF and upper mass limit for star formation are studied. The emerging synthetic spectra are used to discuss the implications on different observational features. Strong emission lines, such as L...
