Various analytical studies (X-ray diffraction study, Raman spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller analysis) were employed in furtherance to explore the structural, morphological, compositional, and surface areal properties of the prepared materials. The enhancement in electrochemical supercapacitive properties were evaluated from pure hexagonal phase WO3 to the various hybrids, depending on the concentration of GO introduced into it, using cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy. The WG-80 composite revealed the high rise in capacitance value of 801.6 F/g overcoming the individual capacitance of rGO (71.11 F/g) and WO3 (94.22 F/g) at a current density of 4 A/g with good cycling stability (75.7%) over 5000 cycles. We have presented quantum capacitance from ab initio calculations and provided theoretical explanation from the orbital interactions.</p>10aDensity functional theory10aHydrothermal method10asupercapacitor10aWO3-rGO hybrids1 aSamal, Rutuparna1 aChakraborty, Brahmananda1 aSaxena, Manav1 aLate, Dattatray, J.1 aRout, Chandra, Sekhar  uhttp://library.ncl.res.in/content/facile-production-mesoporous-wo3-rgo-hybrids-high-performance-supercapacitor-electrodes01845nas a2200217   4500008004100000022001400041245010500055210006900160260000800229300001400237490000700251520109900258653002101357653002401378653002601402653001501428100002201443700001801465700001901483856012501502       2019                        eng d  a1533-488000aHydrothermal growth and humidity-dependent electrical properties of molybdenum disulphide nanosheets0 aHydrothermal growth and humiditydependent electrical properties   cAUG  a5158-51660 v193 a<p>In present investigation, we report humidity dependent electrical properties of molybdenum disulphide (MoS2) nanosheets. MoS2 nanosheets were prepared through a facile hydrothermal method with different reaction temperatures. The as-synthesized MoS2 nanosheets were characterized with XRD, SEM, TEM, and Raman spectroscopy, which confirmed successful preparation and rationality. Further, the humidity dependent electrical properties against relative humidity (RH) of these samples were carried out at room temperature. The results evinced that the sensors film fabricated with MoS2 nanosheets prepared at temperature 220 degrees C exhibited better performance compared to the nanosheets synthesized at 180 degrees C and 200 degrees C temperature. The RH sensing results exhibits highly sensitive, ultrafast response/recovery behaviour and outstanding repeatability than reported earlier. The excellent humidity sensing properties of the resultant MoS2 nanosheets was proved to be an excellent candidate for constructing ultrahigh-performance humidity sensor toward various applications.</p>10aHumidity sensors10aHydrothermal method10aMolybdenum Disulphide10ananosheets1 aShelke, Nitin, T.1 aKarle, S., C.1 aKarche, B., R.  uhttp://library.ncl.res.in/content/hydrothermal-growth-and-humidity-dependent-electrical-properties-molybdenum-disulphide
