Because portable power source is an essential need of such wearable devices, currently there is considerable research emphasis on the development of planar interdigitated micro energy-torage devices by employing diverse precursor materials to obtain functional materials (functional carbon, oxides, etc.) with the desirable set of properties. Herein we report for the first time the use of metal organic framework (MOF) and zeolitic imidazolate framework (ZIF-67) for high-wavelength photothermal laser direct writing of metal-decorated, heteroatom-doped, porous few-layer graphene electrodes for microsupercapacitor application. We argue that the specific attributes of MOF as a precursor and the high-wavelength laser writing approach (which creates extremely high localized and transient temperature (>2500 degrees C) due to strong absorption by lattice vibrations) are together responsible for the peculiar interesting properties of the carbon material thus synthesized, thereby rendering extremely high cycling stability to the corresponding microsupercapacitor device. Our device exhibits near 100% retention after 200 000 cycles as well as stability under 150 degrees bending.1 aBasu, Aniruddha1 aRoy, Kingshuk1 aSharma, Neha1 aNandi, Shyamapada1 aVaidhyanathan, Ramanathan1 aRane, Sunit1 aRode, Chandrashekhar, V.1 aOgale, Satishchandra, B.  uhttps://library.ncl.res.in/content/co2-laser-direct-written-mof-based-metal-decorated-and-heteroatom-doped-porous-graphene02253nas a2200289   4500008004100000022001400041245009500055210006900150260000800219300000900227490000700236520135300243653002001596653001801616653001901634653001401653100001701667700001801684700002201702700001901724700001901743700001601762700002101778700001901799700001901818856012601837       2017                        eng d  a1432-848800aConcurrent synthesis of SnO/SnO2 nanocomposites and their enhanced photocatalytic activity0 aConcurrent synthesis of SnOSnO2 nanocomposites and their enhance  cJAN  a9-170 v213 a<p>The SnO/SnO2 nanocomposites were synthesized using semisolvothermal reaction technique. These nanocomposites were prepared using different combination of solvents viz., ethanol, water, and ethylene glycol at 180 A degrees C for 24 h. The synthesized nanocomposites were analyzed with various characterization techniques. Structural analysis indicates the formation of tetragonal phase of SnO2 for the sample prepared in ethanol, whereas for other solvent combinations, the mixture of SnO and SnO2 having tetragonal crystal structures were observed. The optical study shows enhanced absorbance in the visible region for all the prepared SnO/SnO2 nanocomposites. The observed band gap was found to be in the range of 3.0 to 3.25 eV. Microstructural determinations confirm the formation of nanostructures having spherical as well as rod-like morphology. The size of nanoparticles in ethanol-mediated solvent was found to be in the range of 5 to 7 nm. Thermogravimetric analysis indicate the weight gain around 1.3 wt% confirming the conversion of SnO to SnO2 material. The photocatalytic activity of synthesized nanocomposites was evaluated by following the aqueous methylene blue (MB) degradation. The sample prepared in ethylene glycol-mediated solvent showed highest photoactivity having apparent rate constant (K-app) 0.62 x 10(-2) min(-1).</p>10aDye-degradation10aNanocomposite10aPhotocatalysis10atin oxide1 aRoy, Animesh1 aArbuj, Sudhir1 aWaghadkar, Yogesh1 aShinde, Manish1 aUmarji, Govind1 aRane, Sunit1 aPatil, Kashinath1 aGosavi, Suresh1 aChauhan, Ratna  uhttps://library.ncl.res.in/content/concurrent-synthesis-snosno2-nanocomposites-and-their-enhanced-photocatalytic-activity
