Title: PAN NF supported silver-graphitic carbon nitride (Ag-gC3N4) and Cu: Ni: CNFs Composites: Its property investigation on photocatalytic and super-capacitive properties
Among the nanostructures, polymeric nanofibers have gained lot of research interest in the field of nanotechnology especially in the field of composite science due to their enhanced properties as compared to micron size fibers. Their inherent properties such as high aspect ratio, porosity, stability and permeability makes them an advanced materials with potential application in energy storage devices such as fuel cells, lithium ion batteries, sensors, filters, tissue engineering and drug delivery. The fabrication of nanofibers using electrospinning technique was widely acknowledged due to its easiness of drawing in nano form with desired properties. Read More
Considering the importance and applicability of nanofibers, efforts have been made for the synthesis of nanofibers of various shape and size. polyacrylonitrile nanofiber (PAN NFs) supported silver-graphitic carbon nitride (Ag-gC3N4) and Cu:Ni:CNFs was fabricated by electro spinning technique. Structural and morphological studies (XRD, XPS, SEM and TEM) indicates that the spherical Ag-gC3N4 NPs were well-dispersed on the surfaces of the PAN NFs or embedded in the PAN NFs with deagglomerated form and observed the same in case of Cu: Ni: CNFs. The catalytic potential of PAN/Ag-gC3N4 NFs was developed for oxidation of organic substrate such as styrene, -CH2 bonded molecules and benzene under visible light. The visible light mediated activity of the catalyst could be endorsed to photoactive nature of gC3N4surface.Further, Cu: Ni: CNFs were tested as a possible electrode material for supercapacitor, employing different electrochemical techniques such as CV, GCD and EIS. An impressive electrochemical behavior was observed resulting into high specific capacitance at a current density of 1 A/g compared to CNFs. The electrode material also manifests noteworthy cyclic stability with 79.98 % retention of initial specific capacitance even after 5000 cycles.
Keywords- Silver-graphitic carbon nitride (Ag-gC3N4), Cu: Ni: CNFs, photocatalytic activity, super-capacitive study and morphology study

Title: Ionic Liquids-Based Nanocolloids—Application, Development and Scenarios for Heat Transfer
Fluids are critical for most of the heat transfer processes and there is a tremendous need of enhancing thermal processes, especially in regard to finding new solutions that may support the miniaturization of components for most of the thermal equipment. Another requirement is to get higher heat transfer degrees combined with higher energy conversion possibilities. In terms of properties, a convenient heat transfer fluid needs to tackle, especially, good heat transfer properties, followed by good stability, low viscosity and environment friendly characteristics.

Room-temperature ionic liquids (IL), organic salts that are in a liquid phase at temperatures lower than 100˚C, received significant consideration as possible choices for heat transfer fluids in the last years. IL are non-flammable, non-volatile and recyclable, being considered as green solvents.
Ionic liquids have outstanding characteristics, as for example: good solvating potential, thermal stability and tunable properties (i.e. attained by appropriate selection of cations and anions).
In many ways, ionic liquids are superior to commercial heat transfer fluids mainly in terms of stability, low vapor pressure and environmental protection. A relevant advantage is their easy to design properties by combining anions and cations and this paper aim to shed some light in this process by identifying several possibilities.
A relevant characteristic that differentiates ionic liquids among commercial heat transfer fluids is the remarkably low saturated vapour pressure at high temperature. This makes them particularly salient for special operation under dynamic vacuum or spatial / aerodynamics applications.
A major drawback is the high price, that may be lowered in time due to improving ionic liquids synthesis processes. Nevertheless, the selection of a certain ionic liquid or derivate is subject to a specific application and more coordinated experimental research is needed.
