An acylamide-functionalized 3D microporous metal-organic framework built on Zn2 clusters with mixed H3bcta and dipy ligands, which shows unprecedented 2D → 3D polycatenation based on dipy-pillared honeycomb bilayers, and exhibits highly selective CO2 capture.
The present paper deals with cost-wise comparison of steel reinforcement with bamboo reinforcement. The utilization of bamboo reinforcement as replacement of steel reinforcement is gaining immense importance today, mainly on account of the improvement in the economical aspect combined with ecological benefits.
Controlled Growth and Application in Lithium and Sodium Batteries of High-Aspect-Ratio, Self-Organized Titania Nanotubes, González, José R., Alcántara, Ricardo, Ortiz, Gregorio F., Nacimiento, Francisco, Tirado, José L.
In the present work we demonstrate the synthesis of degradable thermo-sensitive poly(N-vinylcaprolactam) microgels via precipitation polymerization using reactive polyvinylalkoxysiloxanes as crosslinkers (Cross-PAOS). These compounds were synthesized by co-condensation of vinyltriethoxysilane and tetraethoxysilane fol…
Plausible mechanisms of the ultrafast electron injection and the significant dependence of the power conversion efficiency on the anchor group for the triphenylamine-based dye-sensitized TiO2 solar cells have been explored by the density functional calculations. Calculations show that the ultrafast charge recombinatio…
A new type of rechargeable molybdenum–air battery based on the technologies of reversible solid oxide fuel cells and chemical looping is reported in this study. The reversible solid oxide fuel cell serves as the electrical unit to realize the charging and discharging cycles while a pair of Mo/MoO2 redox couple integra…
In this work, we subject bi- and terpyrenyls to selective fusion for formation of extended polycyclic aromatic hydrocarbons (PAHs). Connecting the pyrene units at 4-4'- or 1-4'-positions led to smooth formation of extended PAHs, achieved via cyclodehydrogenation. This is far more difficult if pyrene is coupled in the…
A core–shell nanostructured composite material consisting of nano-Si as the core and SnO2 as the shell is synthesized by a sol–gel method. The reaction mechanism between Li and a nano-Si/SnO2 core–shell nanostructured electrode is investigated, the partial reversible reaction between Li and SnO2 during the first cycle…
Three new isoindigo containing donor–acceptor (D–A) type conjugated polymers were synthesized by palladium catalyzed Suzuki polycondensation and used as donor materials for polymer solar cells (PSCs) and field effect transistors (FETs). All the polymers possess good solubility in common organic solvents, high thermal…
Cobalt is an important metal ion with magnetic properties that is widely used for several industrial applications. Overexposure to cobalt ions can be highly toxic for the organisms because they usually overwhelm the endogenous physiological system that maintains their homeostasis causing (geno)toxic effects. To gain i…
We demonstrate an N719 dye sensitized solar cell based on Cu2FeSnS4 (CFTS) as a counter electrode. The elements for the material are all earth abundant and environmentally benign. The power conversion efficiency of a DSSC using CFTS was comparable to that of a DSSC using Pt under A.M. 1.5G (100 mW cm−2).
3D inverse opal ZnO photonic crystals (ZnO-PCs) with designed photonic bandgap (PBG) were prepared to study the pore size and slow photon effect on photocatalytic dye degradation. The PBGs of these ZnO-PC films were tuned experimentally by variation of the polystyrene sphere size of the opal templates. It was found th…
The study of the mechanism of Li insertion into nanosized partially inverse spinel MnFe2O4 applying X-ray diffraction, in situ quick X-ray absorption spectroscopy, Mössbauer spectroscopy, high resolution transmission electron microscopy, 7Li MAS NMR, and electrochemical measurements yields a comprehensive picture of t…
In this study, several ZnO catalysts were prepared using different zinc sources as precursors. The different catalyst mor- phologies obtained were used to degrade photocatalytically a methyl orange (MO) dye solution, which was used to model wastewater pollution. The precursors, Zn(CH3COO)2, ZnCl2 and Zn(NO3)2, were in…
Colloidal Fe/Ni bimetallic nanoparticles (NPs) have been applied as important materials for environmental remediation applications; however, the reusability of the colloidal Fe/Ni NPs still remains a great issue that limits their environmental applications. In this paper, we developed two different routes to synthesiz…
An investigation has been performed into the pervaporation (PV) of the water–ethanol azeotrope using sulphonated poly(ethersulphone) (SPES)–polyethyleneimine (PEI) membranes, the performance of which is compared to the SPES membrane. The SPES–PEI membranes showed high selectivity because of their alternating electrost…
We have developed an air-stable inverted structure of poly(3-hexylthiophene) (P3HT) : cadmium selenide (CdSe) hybrid solar cells using a cesium-doped ZnO (ZnO:Cs) electron transport layer. The ZnO:Cs layer was simply prepared at low temperature by the sol–gel process using a ZnO solution containing cesium carbonate (C…
Carbon nanotube reinforced aluminium nano-composites were produced using powder metallurgy route with different weight percent of CNT into the Al matrix. The wear behaviour of pure aluminium (Al) and carbon nanotube reinforced aluminium (CNT-Al) nano-composite with different CNT content were studied with a pin-on-disc…
The fabrication of fully transparent thin-film transistor (TFT) arrays composed of metal oxides and SWCNTs was performed on a glass substrate through simple all-solution-processed, vacuum-free routes followed by thermal annealing treatments at 350 °C which is the lowest processing temperature reported to date. We adop…
We developed a two-step hydrothermal method to prepare hetero-structured TiO2 nanotree arrays on FTO substrates. This process included the deposition of rutile nanorod arrays with a length of about 2 μm as trunks at first and then the growth of the anatase nanosheets with the thickness of less than 10 nm standing on t…
