4Hydroxy-2H Chromenes are fused benzopyran rings, an important class of biologically active compounds, widely used as antibacterial, antiviral, antitumor, and anticancer agents. In this present paper, we report the 4 Hydroxy-2H Chromenes synthesis by using two catalysts namely, (i) ZnO nanoparticles and (ii) mesoporous ZnO/AlSBA-15 (7) catalysts. The ZnO NP catalyst was prepared by using leaf extract while ZnO/AlSBA-15(7) catalysts were prepared by the wet chemical route. All catalysts were characterized by XRD, SEM, EDS, FTIR, and N2 sorption techniques. The catalytic activity of the synthesized catalyst was evaluated in the one-pot reaction using aromatic aldehyde and Coumarin, and found to be maximum yield of 81% at temperature 80°C, a catalyst dose of 10 mmol %, in time limit of 4h.

Bimetallic Oxides

Nickel-based bimetallic oxides (BMOs) have shown significant potential in battery-type electrodes for pseudo-capacitors given their ability to facilitate redox reactions. In this work, two bimetallic oxides, NiMoO4 and NiWO4, were synthesized using a wet chemical route. The structure and electrochemical properties of the pseudo-capacitor cathode materials were characterized. NiMoO4 showed superior charge storage performance in comparison to NiWO4, exhibiting a discharge capacitance of 124 and 77 F.g−1, respectively. NiMoO4, moreover, demonstrates better capacity retention after 1000 cycles with 87.14% compared to 82.22% for NiWO4. The lower electrochemical performance of the latter was identified to result from the redox behavior during cycling. NiWO4 reacts in the alkaline solution and forms a passivation layer composed of WO3 on the electrode, while in contrast, the redox behavior of NiMoO4 is fully reversible.

Aluminium Nitrate Nonahydrate

Silica based ceramics are some of the most fundamental in crystal chemistry. The cristobalite form of silica has two modifications, α (low temperature, tetragonal form) and β (high temperature, cubic form). This paper describes our structural studies of unusual chemically stabilized cristobalite (CSC) material, a room temperature silica-based ceramic containing small amounts of dopants, prepared by a wet chemical route. It displays many of the structural charatcteristics of the high temperature β-cristobalite (∼270°C), but does not undergo phase inversion to α-cristobalite upon cooling. The Structure of α-cristobalite is well established, but that of β is not yet fully understood.Compositions with varying Ca/Al ratio and substitutions in cristobalite were prepared in the series, CaO:Al2O3:SiO2 : 3-x: x : 40, with x= 0-3. For CSC, a clear sol was prepared from Du Pont colloidal silica, Ludox AS-40®, aluminium nitrate nonahydrate, and calcium nitrate hexahydrate in proportions to form a final composition 1:2:40 composition.
