One-dimensional NiMoO4 · nH2O nanorods and their graphene based hybrid composite with good electrochemical properties have been synthesized by a cost effective hydrothermal procedure. The formation of the mixed metal oxide and the composite was confirmed by XRD, XPS and Raman analyses. The morphological characterizations were carried out using FESEM and TEM analyses. The materials were subjected to electrochemical characterization through cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS) studies with 6 M KOH as the supporting electrolyte. For NiMoO4 · nH2O, a maximum specific capacitance of 161 F g(-1) was obtained at 5 A g(-1) current density, accompanied with an energy density of 4.53 W h kg(-1) at a steady power delivery rate of 1125 W kg(-1). The high utility of the pseudocapacitive NiMoO4 · nH2O was achieved in its graphene based composite, which exhibited a high specific capacitance of 367 F g(-1) at 5 A g(-1) current density and a high energy density of 10.32 W h kg(-1) at a power density of 1125 W kg(-1) accompanied with long term cyclic stability.

IntroductionWith the rising progress of global economy and industry, the impending energy crisis has stimulated intense research on the low cost, environmentally friendly, and renewable energy resources. [ 1 ] Therefore, great efforts have been devoted to develop low cost electrode materials with high energy density, high power density, and excellent cycling stability. Supercapacitors, can be considered as the supreme candidate of the nextgeneration energy storage/conversion systems with the unique ability to store energy in a fraction of second and delivering the stored energy rapid enough than any other conventional energy storage devices. It also ensures high power density when coupled with batteries or fuel cells. [1][2][3][4] However, the supercapacitors suffer from low working potential that result in low energy density than conventional batteries. So, it's essential to improve their performances to encounter the higher requirements of future technologies by developing new materials with the interfaces at the nanoscale dimension. Lower specifi c energy of electrochemical double layer capacitors (EDLCs) with respect to the batteries and lower power densities of pseudocapacitors than EDLCs has motivated to develop the better performance characteristics hybrid supercapacitors. These hybrid supercapacitors use both Faradaic and non-Faradaic processes to store charge and thereby have achieved higher energy density and moderated power density accompanied with high cycling stability and thus have restricted the monopolism of pseudocapacitor.Intense research has established that combination of the micro structured carbonaceous materials with electroactive materials into a single system can take the benefi ts of both the double layer capacitance and pseudocapacitance arising from the synergistic interaction of the two. In this sense, graphene is the most interesting carbonaceous material with ultrahigh surface area (2600 m 2 g −1 ), excellent electric conductivity, two-dimensional sp 2 carbon arrangement with one-atom thickness. However, the strong electrostatic interaction amongst the graphene sheets leads to restacking of the sheets resulting in lower specifi c surface area and lower capacitance. [ 5 ] This drawbacks can be overcome by functionalization on the surface or incorporating nanocrystals in form of nanocomposites. The conducting polymers and transition metal oxides are two typical pseudocapacitive materials, which are capable of storing more charges than carbonaceous materials, but are limited by their poor stability and high resistance during cycling. The conducting polymer is frequently used into supercapacitor materials for obtaining the effi cient charge storage and delivery which strongly depends on the orientation of polymer chains into inorganic host. The polymer molecules are directed to grow along the large oriented tunnels of 3D hosts or interlayer space of the 2D hosts where the structurally organized frameworks are provided by the inorganic ...

On July 23, 2014, the FDA granted accelerated approval to idelalisib (Zydelig tablets; Gilead Sciences, Inc.) for the treatment of patients with relapsed follicular B-cell non-Hodgkin lymphoma or relapsed small lymphocytic lymphoma (SLL) who have received at least two prior systemic therapies. In a multicenter, single-arm trial, 123 patients with relapsed indolent non-Hodgkin lymphomas received idelalisib, 150 mg orally twice daily. In patients with follicular lymphoma, the overall response rate (ORR) was 54%, and the median duration of response (DOR) was not evaluable; median follow-up was 8.1 months. In patients with SLL, the ORR was 58% and the median DOR was 11.9 months. One-half of patients experienced a serious adverse reaction of pneumonia, pyrexia, sepsis, febrile neutropenia, diarrhea, or pneumonitis. Other common adverse reactions were abdominal pain, nausea, fatigue, cough, dyspnea, and rash. Common treatment-emergent laboratory abnormalities were elevations in alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase, absolute lymphocytes, and triglycerides. Continued approval may be contingent upon verification of clinical benefit in confirmatory trials.

A unique and cost effective hydrothermal procedure has been carried out for the synthesis of hexahedron shaped α MnMoO4 and its hybrid composite with graphene using three different weight percentages of graphene. Characterization techniques, such as XRD, Raman and FTIR analysis, established the phase and formation of the composite. The electrochemical characterization of the pseudocapacitive MnMoO4 and the MnMoO4/graphene composites in 1 M Na2SO4 displayed highest specific capacitances of 234 F g(-1) and 364 F g(-1), respectively at a current density of 2 A g(-1). Unlike many other pseudocapacitive electrode materials our prepared materials responded in a wide range of working potentials of (-)1 V to (+)1 V, which indeed resulted in a high energy density without substantial loss of power density. The highest energy densities of 130 Wh kg(-1) and 202.2 Wh kg(-1) were achieved, respectively for the MnMoO4 and the MnMoO4/graphene composite at a constant power delivery rate of 2000 W kg(-1). The synergistic effect of the graphene with the pseudocapacitive MnMoO4 caused an increased cycle stability of 88% specific capacitance retention after 1000 consecutive charge discharge cycles at 8 A g(-1) constant current density, which was higher than the virgin MnMoO4 with 84% specific capacitance retention.
