In this work, we report a facile and green reduction method to synthesize reduced graphene oxide (rGO) sheet by using epigallocatechin gallate (EGCG) and hydroiodic acid (HI) simultaneously as a reduction agents and investigate its efficiency as an electrode. Two steps reduction and modification of graphene oxide GO with epigallocatechin gallate (EGCG) as a green reductant and hydroiodic acid (HI) as strong chemical reducing agent are investigated in this work. The indication of the reduction efficiency of rGO surface was determined by scanning electron microscopy (SEM). The results showed that using both of the reductants simultaneously was effective for removing oxygen-containing functional groups in GO to obtain rGO. The rGO obtained from these two-step processes had C/O ratio of about ∼10.26 and conductivity of 2385 S/m. The results also show that the presence of EGCG in the final rGo sheet provides active sites for furthered modification of rGO such as decorating it with metal nanoparticles in a single-step chemical deposition. These features will facilitate its further use as a flexible electrode in composite materials of conductors and many other applications.
A feasibility studyfortheapproval of liquid metalseedsrecovery froma liquid metalvapor-inert gasmixture was conducted and presented in this report. The research activity included background studies on processes relating tomixingstream condenser performance, parametric studies and its experimental validation.The condensation processunder studyincludesmass transfer phenomena combined withheattransfer and phasechange. Numerical methodswereusedinorder tosolve thedynamicequations and tocarry out the parametric study as well as the experimental data reduction. The MSC performance is highly effected by droplet diameter, thus the possibility of atomizing liquid metals were experimentally investigated.The results are generalized and finally used for a set of recommendations by which the recovery of seeds is expected to be feasible.
Recently, we discovered a novel, nonchemical, method to create nanoporous palladium through an electrical wire explosion [8]. Others have used electrical wire explosions to produce metal nanopowders, but not nanoporous metals [9]. In our experiment, with the intended application to high energy density physics, deuterium loaded wires were pulsed with a low energy pulse, a so
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
