Water inhibits sulfate deposition and enhances the surface acidity during the sulfation of MnO <sub>x</sub> –CeO <sub>2</sub> /Al <sub>2</sub> O <sub>3</sub> , which promotes soot oxidation.
Graphite oxide has attracted much interest as a possible route for preparation of natural graphite in the largescale production and manipulation of graphene as a material with extraordinary electronic properties. Graphite oxide was prepared by modified Hummers method from purified natural graphite sample from West Kal…
The main aim of this study was to investigate the effect of deposition time on the physicochemical and photoelectrochemical properties of cupric oxide (CuO) thin films synthesized via electrodeposition method. Firstly, the electrodeposition of amorphous CuO films on fluorine-doped tin oxide (FTO) working electrodes wi…
The present paper reports on the facile formation of ZnO nanorod photocatalyst electrodeposited on Zn foil in the production of hydrogen gas via water photoelectrolysis. Based on the results, ZnO nanorod films were successfully grown via electrochemical deposition in an optimum electrolyte set of 0.5 mM zinc chloride…
Ultrasensitive detection of formaldehyde by coupling enzyme activity with GNP synthesis.
The core–shell structure of surface conductive SiO <sub>2</sub> @rGO could result in enhanced electrical conductivity and EMI shielding effectiveness as due to both synergistic effect and volume exclusion effect.
Cellulase-directed synthesis of magic numbered Cu NCs with blue-, cyan-, and green emission from Cu <sub>12</sub> , Cu <sub>20</sub> , and Cu <sub>34</sub> , respectively is presented. The random coil structure of enzyme dictates the size and luminescent properties of Cu NCs.
In this work the process of PLA hydrolysis at high temperature was studied, in order to evaluate the possibility of chemical recycling of this polymer bio-based. In particular, the possibility to obtain the monomer of lactic acid from PLA degradation was investigated. The results of some preliminary tests, performed i…
The temperature-dependent luminescence characteristic of CaSc 2 O 4 :Ce 3+ phosphor has been investigated. Huang-Rhys coupling factor, Stokes shift, activation energy, and quenching temperature of CaSc 2 O 4: Ce 3+ phosphor was determined. The quenching mechanism of CaSc 2 O 4: Ce 3+ phosphor was also studied. Finally…
Micro-patterned surfaces with alternate hydrophilic and hydrophobic rectangular areas effectively confine water droplets down to attolitre volumes. The contact angle, volume, and geometry of the confined droplets as a function of the geometry and physico-chemical properties of the confining surfaces have been determin…
In this work, we have fabricated transparent cellulose acetate/graphene oxide nanocomposite (CAGONC) films for ultraviolet radiations (UVR) shielding. Graphene oxide (GO) was synthesized by modified Hummer’s method and CAGONC films were fabricated by solvent casting method. The films were analyzed using characterizati…
The distribution of potassium (K) forms, their inter-relationship and relation with soil properties and clay mineralogy was studied in soils under different agro-ecological sub-regions of Punjab. Surface (0–30 cm) soil samples were analyzed for physico-chemical properties, soil mineralogy and K forms. The XRD analyses…
We report here how the crystallinity of AuNPs and the choice of binding sites of molecular cross-linkers control their aggregation. The combination of different binding moieties (N-oxides, ArF-I) and the reactivity of the particles' facets allow control over the organization and crystallinity of the AuNP assemblies.
“New bisazobenzene derivatives with remarkable and reversible response to optical and chemical stimuli were synthetized and characterized”.
Superhydrophobicity is generally dependent on a material's surface energy and surface roughness, which controls the formation of a stable composite interface with air pockets between the solid substrate and liquid.
In present work Cu2S thin film fabricated on glass substrate by simple, cost effective chemical bath deposition method subsequently it annealed at 150°c.These films were studied for their structural, optical and electrical properties using X-ray diffraction, UV-vis spectrophotometer and I-V system. The results show su…
The conductivity and optical transmission of ITO thin films, produced from nanoparticle suspensions, are improved by microwave post annealing.
A series of Pd6L4-type neutral coordination cages, [Pd6X12L4] (X(-) = Cl(-) and Br(-)), are constructed via self-assembly of (COD)PdCl2 and K2PdBr4 with C3-symmetric N,N',N''-tris(2-pyridinylmethyl)-1,3,5-benzenetricarboxamide (L), respectively. The iodide analogue [Pd6I12L4] is smoothly synthesized from [Pd6Br12L4] i…
Ultrasonic monitoring of decomposition of hydrogen peroxide catalyzed by metal surfaces.
This work describes the corrosion management of carbon steel structures of a firewater distribution system under laboratory conditions. The influence of operational modes i.e. regular replacement and extended stagnant condition of firewater were tested. Corrosion rate at different experimental conditions was determine…
