Enhancement of thermal properties of conventional heat transfer flu.ds has become one of the important technical challenges. Since nanoflu.ds offer a promising help in this regard, development of simpler and hassle free rou.es for their synthesis is of u.most importance. Synthesis of nanoflu.ds u.ing a hassle free rou.e with greener chemicals has been reported. The single-step chemical approach reported here overcomes the drawbacks of the two-step procedu.es in the synthesis of nanoflu.ds. The resu.ting Newtonian nanoflu.ds prepared contained cu.octahedral particles of cu.rou. oxide and exhibited a thermal condu.tivity of 2.852 W- m-1. K-1. Polyvinylpyrro- lidone （PVP） u.ed du.ing the synthesis acted as a stabilizing agent rendering the nanoflu.d a stability of 9 weeks.

Novel bariu. tu.gstate/nitrogen-doped redu.ed graphene oxide-graphi- tic carbon nitride （BaWO4/NRGO-g-C3N4） nanocomposite has been synthesized by a simple one-pot microwave techniqu.. The synthesized nanocomposites are well characterized by diffraction, microscopic and spectroscopic techniqu.s to stu.y its crystal stru.tu.e, elemental composition, morphological featu.es and optical properties. The material prepared is tested for its performance as an electrocatalyst, photocatalyst and redu.tion catalyst. The nanocomposite catalyzed the photodegradation of methylene blu. （MB） dye in 120 min, redu.tion of 4-nitro phenol （4-NP） to 4-amino phenol （4-AP） in 60 s, showed an impressive Tafel slope of 62 mV/dec for hydrogen evolu.ion reaction （HER）. The observed resu.ts su.gest that the nanocomposite acts as an efficient mu.tifu.ctional catalyst. The reported approach provides fu.damental insights which can be extended to other metal tu.gstate-based ternary composites for applications in the field of clean energy and environment in the fu.u.e.
