Due to its excellent capacity, around 4000 mA h g−1, silicon has been recognized as one of the most promising lithium-ion battery anodes, especially for future large-scale applications including electrical vehicles and utility power grids. Nevertheless, Si suffers from a short cycle life as well as limitations for sca…
Two different nanostructured copper–isonicotinic acid (INA) coordination polymers, Cu(C6H4NO2)2(H2O)4 and [Cu(C6H4NO2)(OH)]H2O have been successfully synthesized under hydrothermal conditions on a large scale without the assistance of surfactants or template. Cu(C6H4NO2)2(H2O)4 has the morphology of 2-dimensional (2D)…
A new triangular metamaterials (TMMs) is designed for electromagnetic (EM) absorption reduction at microwave frequencies in this paper.The reduction of EM absorption with a new TMMs attachment is investigated in this research.The finite-difference time-domain method with lossy-Drude model is adopted in this investigat…
To compare the composition and performance of various lignocellulosic biomass hydrolysates as fermentation media, 8 hydrolysates were generated from a grass-like and a wood biomass. The hydrolysate preparation methods used were 1) dilute acid, 2) mild alkaline, 3) alkaline/peracetic acid, and 4) concentrated acid. The…
High quality, single crystalline, ordered arrays of a π-conjugated organic molecule, N,N′-dioctyl-3,4,9,10-perylene tetracarboxylic diimide (PTCDI-C8), were grown by solution processing and used to fabricate a low-cost, high-performance organic phototransistor (OPT). The single crystalline nature of the microstructure…
Three porphyrin dyes, P1, P2 and P3, bearing one, two and four pyridyl groups, respectively, in the meso positions, acting as electron acceptor anchoring groups, were synthesized, characterized and investigated as sensitizers for the fabrication of dye sensitized solar cells (DSSCs). The overall power conversion effic…
New porous bipyramid, fusiform and plate structured NiMn2O4 materials have been successfully synthesized by calcining oxalate precursors in the air without using any template or surfactant. More importantly, electrochemical measurements show that morphology affects their electrochemical properties, and the porous plat…
Two new Co(II) coordination polymers with a pyridinedicarboxylate ligand, {[Co(L)(H(2)O)]·H(2)O}(n) (1) and [Co(3)(HCOO)(2)(L)(2)(H(2)O)(2)](n) (2) (H(2)L = 5-(pyridin-4-yl)isophthalic acid), have been synthesized and structurally characterized by elemental analysis, IR, XRPD, and single-crystal X-ray diffraction. Str…
A new strategy for synthesis of Pt nanocubes on various supports by reduction of a Pt precursor under a CO atmosphere was described. The as-prepared Pt nanocubes supported on multi-walled carbon nanotubes exhibited high activity toward methanol electrooxidation.
A redox-active Fe(CN)6−4-doped polypyrrole was synthesized and found to have a remarkable redox capacity of 135 mA h g−1 in Na+ electrolyte, an excellent rate capability of 1600 mA g−1 and a strong capacity retention of 85% over 100 cycles, showing great promise for enabling low-cost and environmentally benign Na-ion…
The achiral chelating and bridging mesoxalato ligand (H2mesox2−), the conjugate base of mesoxalic or dihydroxymalonic acid (H4mesox), is a new enantiopurity enforcer in extended structures by yielding the Λ/Δ-metal configured homochiral MOFs 2D-[Ln2(μ-H2mesox)3(H2O)6], [with Ln(III) = La (1), Ce (2), Pr (3), Nd (4), S…
The replacement of the pillar ligand, 4,4'-bipyridine, in the prototypal pillared MOF, MOF-508, with the custom-designed ligand, 4,4'-(2H-1,2,3-triazole-2,4-diyl)dipyridine, affords a porous metal-triazolate framework, MTAF-3, which demonstrates remarkable enhancement of CO(2) uptake capacity by a factor of ~3 compare…
We investigated the effects of direct solvent exposure on the properties of [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) films and poly(3-hexylthiophene) (P3HT)/PCBM blend films employed as active layers in, respectively, organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The crystallinity…
Three-armed star polymers with a cyclodextrin core and polyacrylamide arms were prepared via inclusion complex formation. A novel adamantyl-functionalized chain transfer agent was utilized in the reversible addition–fragmentation chain transfer (RAFT) polymerization of N,N-dimethylacrylamide and N,N-diethylacrylamide…
In the design of efficient sensitizers for dye-sensitized solar cells (DSSCs), it is vital to modulate the HOMO and LUMO orbitals by introducing suitable donor and acceptor groups. In this respect, triphenylamine has been extensively used as the donor group. Porphyrin has strong absorption in the UV-Vis range, which m…
A novel structurally simple calix[4]arene appended 8-amidoquinoline linked conjugate was synthesized and has been used as a turn-on fluorescence probe for Zn(2+) and turn off fluorescence probe for F(-). Moreover, this probe has been applied for Zn(2+) detection in blood serum upto 8.7 μM and fluoride detection upto 2…
We report a facile, two-step hydrothermal growth method to synthesize a novel hierarchical SnO2–Fe2O3 heterostructure, consisting of a micron-sized primary SnO2 nanosheet base and sub-10 nm diameter Fe2O3 nanorod branches grown on the nanosheet surface. In addition to the high theoretical lithium storage capacities of…
Very sophisticated porous materials known as multivariate functional MOFs (also known as MixMOFs) can be designed using a synthesis method that starts from solutions composed of two or more different linkers. For this procedure to be successful, one must have access to techniques that characterize the homogeneity of M…
