The oligomer salt was derived from 4-amino benzoic acid as the monomer by a facile free radical polymerization process. Incorporation of the functional groups (-COONa) eliminate the need for any external activating agents (KOH, ZnCl2, etc.) and also render high degree of sub-nanoscale homogeneity. This oligomer derived carbon (ODC) exhibits efficient performance in non-aqueous charge storage application namely Li-ion hybrid electrochemical capacitor (Li-HEC) owing to its high surface area, 3D interconnectivity and an appropriate pore size distribution. The Li-HEC fabricated with ODC based electrodes delivered a maximum energy density of similar to 63 Wh kg(-1) with spinel L4Ti5O12 as the anode. (C) 2014 Elsevier Ltd.

One ternary system of interest in this context is cadmium tin oxide (Cd2SnO4), which supports the cubic and orthorhombic phases with optical, electronic and catalytic properties that are favourable for PEC water splitting. However, its practical PEC performance is limited by high surface recombination of the photogenerated charge carriers. In this work we circumvent this problem by engineering the constitution of Cd2SnO4 nanoparticles to a biphasic nanojunction form, comprising of a nanocomposite of cubic and orthorhombic phases. The favourable conduction band alignment between the cubic and orthorhombic phases leads to a dramatic reduction in the recombination of the photogenerated charges, leading to a 10-fold increase (from 250 mu A cm(2) to over 2 mA cm(2)) in the photocurrent vis-a-vis the single cubic or orthorhombic phase performance. We discuss the underlying mechanism for the observed dramatic enhancement in the water splitting efficiency.</p>1 aDeshpande, Aparna1 aKelkar, Sarika, A.1 aRayalu, Sadhana1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/orthorhombiccubic-cd2sno4-nanojunctions-enhancing-solar-water-splitting-efficiency-002140nas a2200313   4500008004100000022001400041245013500055210006900190260000900259300001600268490000700284520108400291653001901375653004001394653002201434653001901456653001601475100001701491700002501508700001401533700001801547700001601565700002001581700003101601700002301632700002301655700002501678856012301703       2021                        eng d  a1433-785100aOrganic-inorganic perovskitoid with zwitterion cysteamine linker and its crystal-crystal transformation to ruddlesden-popper phase0 aOrganicinorganic perovskitoid with zwitterion cysteamine linker   cAUG   a18750-187600 v603 aWe demonstrate synthesis of a new low-D hybrid perovskitoid (a perovskite-like hybrid halide structure, yellow crystals, P21/n space group) using zwitterion cysteamine (2-aminoethanethiol) linker, and its remarkable molecular diffusion-controlled crystal-to-crystal transformation to Ruddlesden-Popper phase (Red crystals, Pnma space group). Our stable intermediate perovskitoid distinctly differs from all previous reports by way of a unique staggered arrangement of holes in the puckered 2D configuration with a face-sharing connection between the corrugated-1D double chains. The PL intensity for the yellow phase is 5 orders higher as compared to the red phase and the corresponding average lifetime is also fairly long (143 ns). First principles DFT calculations conform very well with the experimental band gap data. We demonstrate applicability of the new perovskitoid yellow phase as an excellent active layer in a self-powered photodetector and for selective detection of Ni2+ via On-Off-On photoluminescence (PL) based on its composite with few-layer black phosphorous.10aCrystal growth10aorganic-inorganic hybrid composites10aperovskite phases10aphotodetectors10azwitterions1 aKour, Prachi1 aReddy, Mallu, Chenna1 aPal, Shiv1 aSidhik, Siraj1 aDas, Tisita1 aPandey, Padmini1 aMukherjee, Shatabdi, Porel1 aChakraborty, Sudip1 aMohite, Aditya, D.1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/organic-inorganic-perovskitoid-zwitterion-cysteamine-linker-and-its-crystal-crystal
