The search for a novel anode candidate is the key hurdle associated with SIBs. Objective and Method: A novel anode contender, Be-doped graphene, is proposed for the SIBs through our first-principles calculations. Results: The integration of Be can cause a 6 times increment in the adsorption of Na as revealed by M06-2X calculations. The sodiation potential is in a good range in order to evade the security concerns caused by the dendrite formation. A total of 10 Na ions are attached easily around on beryllium (Be) centre in graphene sheet causing an enhancement in the Na storage capacity. The value of storage capacity calculated for Na8BeC17 is 2.7 times that of graphitic carbon in LIBs (~370 mAh/g), and 3.35 times that of hard carbon in SIBs (300 mAh/g). Conclusion: These results show the novelty and promising potential of the Be-doped graphene to be used as anode material for SIBs.

Thus, graphene has stimulated and is still motivating several researchers to widen its potentialities that are currently being exploited in different application sectors, comprising catalysis and energy, nanoelectronics, quantum physics and the design and manufacturing of advanced nanocomposite materials and biomaterials. Being a carbon source, already organized in a well-ordered morphology, graphene is nowadays starting to experience a different application, i.e. in the fire retardancy of polymers, foams and textiles, often in combination with other flame retardant additives or nanofillers, with which graphene can often act in a synergistic way. In fact, it is well reported in the scientific literature that graphene and its derivatives can play a key role either in slowing down the flame propagation or even in providing self-extinction to the thermoplastic or thermosetting matrices, where the nanofiller is incorporated in; furthermore, by exploiting surface engineered approaches, it is possible to design very effective flame retardant coatings on textile substrates. Objective: This paper aims at reviewing the current state-of-the-art about the use of graphene and its derivatives as efficient flame retardant additives for different polymeric materials, highlighting the current limitations/achievements and discussing some possible future developments.

The fabric showed satisfactory conductivity in terms of surface and volume resistivity and decay time. Objective: Conducting graphene coated fabric was fabricated by chemically reducing graphene oxide (GO) on polyester fabrics by using sodium hydrosulphite from an exhaust bath. Method: The characterization of the fabric was performed by X-ray diffraction, Fourier transform infrared spectroscopy. The conducting nature of the fabric was established by measuring surface resistivity, volume resistivity and static charge decay time. Results: Mechanical properties as well as contact angle of the treated fabrics was also measured. Graphene coated fabric showed excellent conductivity and hydrophobic nature. Conclusion: The resultant textile material can be used as an electroconductive, antistatic, hydrophobic product which include carpets for computer rooms, upholstery, fabrics and airbags for automobiles, conveyor belts, filtration fabrics, airmail bags, parachutes, fabrics for hospital operating rooms, and protective clothing for work with flammable gases and liquids.
