“…They are being aggressively exploited to meet many of the current and future needs in the fields of energy, computing, security, life sciences and healthcare. In fact, more and more new carbon materials continue to be discovered and are artificially prepared [1,2]. Among them, carbon nanotubes (CNTs) [3] is an interesting group of carbon materials grabbing attention nowadays due to their unique optical, electronic, and mechanical properties, along with chemical integrity [4].…”

Thin films of organic moiety functionalized carbon nanotubes (CNTs) from a very well-dispersed aqueous solution were designed on a screen printed transducer surface through a single step directed assembly methodology. Very high density of CNTs was obtained on the screen printed electrode surface, with the formation of a thin and uniform layer on transducer substrate. Functionalized CNTs were characterized by X-ray diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and Brunauer–Emmett–Teller (BET) surface area analyzer methodologies, while CNT coated screen printed transducer platform was analyzed by scanning electron microscopy (SEM), atomic force microscopy (AFM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The proposed methodology makes use of a minimum amount of CNTs and toxic solvents, and is successfully demonstrated to form thin films over macroscopic areas of screen printed carbon transducer surface. The CNT coated screen printed transducer surface was integrated in the fabrication of electrochemical aptasensors for breast cancer biomarker analysis. This CNT coated platform can be applied to immobilize enzymes, antibodies and DNA in the construction of biosensor for a broad spectrum of applications.

“…18 These excellent properties indicate that rGO is a potential desensitizing component for high-energy explosives. 19 In recent years, extensive research has been carried out on the preparation and application of graphene nanomaterials in energetic materials. 20,21 Examples of these nanomaterials include insensitive HMX/GO composites, surface-coated insensitive HMX with Viton and GO, HMX coated with graphene oxide by electrostatic self-assembly, graphene nanoplatelet-lead styphnate composites with depressed electrostatic hazards, CL-20 hosted in graphene foam, and insensitive 3-HNIW with binders and graphite.…”

Composites of 1,3,5,7-tetranitro-1,3,5,7-tetrazocane/reduced graphene oxide/graphite (HMX/rGO/G) were successfully prepared via an in situ chemical reduction coating method. The morphology, composition and thermal decomposition characteristic of the composites were analyzed by field-emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Raman spectroscopy and differential thermal analysis (DTA). rGO together with G exhibited a better desensitizing effect than fullerene and carbon nanotubes. When 1.0 wt% GO and 1.0 wt% G were added as desensitizing materials, the impact sensitivity of raw HMX decreased from 100% to 8% and the friction sensitivity decreased from 100% to 0% after in situ chemical reduction coating. Meanwhile, DTA results indicated that rGO and G were compatible with HMX. These combined properties suggest that rGO sheets along with graphite can be utilized as co-desensitizers in HMX explosives.

“…Any energetic material, before its direct use in propellant formulations, needs to be tested for its stability, sensitivity and compatibility with additives that help with the processing of the energetic ingredients [9,10]. Besides the advantage of low sensitivity, GUDN burns at an extremely low temperature, which is important in automatic guns where barrel erosion is often a problem [11]. Thermal and compatibility studies of GUDN based compositions are one of the interesting areas in the field of insensitive munition systems.…”

Guanylurea dinitramide ) is a stable salt of dinitramidic acid with good thermal stability, and is a good candidate for insensitive formulations. Thermal analysis reveals the compatibility of GUDN with benchmark explosives such as RDX and TNT in melt cast explosive formulations. The paper describes a thermal and sensitivity study of GUDN with RDX and TNT. In the present study GUDN was evaluated as a possible replacement for RDX/ TNT based aluminized and non aluminized melt cast explosive formulations. The thermal properties of the composition were investigated as well as its sensitivity to impact and friction. Its thermal decomposition behavior was compared to a control composition based on RDX and TNT. The thermal and sensitivity results proved the worth of these compositions for melt cast explosive applications.
