Self-assembled ultra small ZnO nanocrystals for dye-sensitized solar cell application

Highlights•Synthesis of self-assembled ultra-small mesoporous ZnO nanocrystals by using sodium salicylate as a template.•Mesoporous ZnO materials have high BET surface areas and void space.•ZnO nanoparticles serve as a photoanode for the dye-sensitized solar cell (DSSC).•Using ZnO nanocrystals as photoelectrode power conversion efficiency of 1.12% has been achieved.

Site-selective multicomponent synthesis of densely substituted 2-oxo dihydropyrroles catalyzed by clean, reusable, and heterogeneous TiO2 nanopowder

AbstractAn efficient method for the synthesis of densely substituted 2-oxo dihydropyrroles has been demonstrated by clean, reusable, and heterogeneous catalyst titanium dioxide (TiO2) nanopowder by the four component coupling reaction of dialkyl but-2-ynedioate, two different amines, and an aldehyde. The reaction is site-selective with respect to aromatic and aliphatic amines. Environmentally benign reaction procedure, excellent yields, tolerance of varieties of functionalities in the reactants, a wide variety of products and reusability of the catalyst make the methodology highly beneficial for the synthesis of polyfunctional dihydropyrroles.

Competing order parameters and a tricritical point with a difference

AbstractWe propose a mean-field, phenomenological Ginzburg–Landau free energy functional with two competing order parameters for a two-component, spin-polarized Fermi gas. This free energy supports a tricritical point which is different from the conventional one and this change offers a correct understanding of the experimental phase diagram of imbalanced Fermi systems (Shin et al. (2008) [17]). The specific heat also happens to be different than in standard theory.

Porous organic–inorganic hybrid nickel phosphonate: Adsorption and catalytic applications

AbstractA new crystalline porous organic–inorganic hybrid nickel phosphonate material HPNP-1 has been synthesized hydrothermally in the absence of any template or structure-directing agent (SDA) using an organophosphorus precursor hexamethylenediamine-N, N, N′, N′-tetrakis-(methylphosphonic acid) (HDTMP). Powder XRD results suggested the formation of a new tetragonal phase (a = 14.169 Å; c = 16.202 Å and unit cell volume 3252.8 Å3) and N2 sorption analyses revealed the existence of supermicroporous along with inter particle mesoporosity in this material. FT IR and UV–vis spectroscopic results suggested that the organic moiety of the organophosphorus precursor molecule has been preserved in this hybrid framework. Due to the presence of surface phosphonate groups this organic–inorganic hybrid material shows very high affinity for the adsorption of metal cations like Cr3+, Pb2+, Hg2+ and Cd2+, and thus can be very efficiently utilized in the adsorption of these heavy metal ions from polluted water. Further, the material showed excellent catalytic activity and selectivity in the reduction of nitrobenzenes to the respective anilines in the presence of NaBH4 as the reducing agent.
