Furan substituted diketopyrrolopyrrole (DBF) combined with benzothiadiazole based polymer semiconductor PDPP-FBF has been synthesized and evaluated as an ambipolar semiconductor in organic thin-film transistors. Hole and electron mobilities as high as 0.20 cm(2) V(-1) s(-1) and 0.56 cm(2) V(-1) s(-1), respectively, ar…
Ionic liquids (ILs) with different cations and anions were used to study the effects on 5-hydroxymethylfurfural (HMF) preparation. It was found that both aggregations of cations and hydrogen bonds of anions with fructose played important roles. Molecular dynamics simulations were also performed to explain the experime…
α-Fe(2)O(3) nanowall arrays (NWAs) were grown directly on Ni foam by a facile hydrothermal method. Based on time-dependent experiment results, a possible formation mechanism for this structure was proposed. The as-prepared α-Fe(2)O(3) samples have an open network structure constituted of interconnected nanowalls and c…
DC power flow can be controlled though N-1 different DC lines/cables in a DC grid having N individual AC/DC converters. A large meshed DC grid can have more DC lines, and since we can not control power in all lines/cables, an overload may result. In this paper, two methods are proposed for DC power flow control throug…
In the search of new materials characterized by high two-photon absorption (TPA) efficiency, many efforts have been devoted to design chromophores with enhanced TPA responses progressively moving from linear chromophores such as dipoles and quadrupoles toward multimeric complex molecular architectures. This approach i…
Substrate-supported noble metallic nanoparticles have received intense attention owing to their great potential in various applications. In this work, silica nanotube-supported metallic nanoparticles (i.e., Au, Ag, and Pd) are synthesized by in situ reducing metal ions into nanoparticles on the nanotube surface. The s…
We report on the development of photosensitizer-conjugated gold nanorods (MMP2P-GNR) in which photosensitizers were conjugated onto the surface of gold nanorods (GNR) via a protease-cleavable peptide linker. We hypothesized that fluorescence and phototoxicity of the conjugated photosensitizers would be suppressed in t…
Activated carbon (AC) air cathodes were constructed using variable amounts of carbon (43–171 mg cm−2) and an inexpensive binder (10 wt% polytetrafluoroethylene, PTFE), and with or without a porous cloth wipe-based diffusion layer (DL) that was sealed with PDMS. The cathodes with the highest AC loading of 171 mg cm−2,…
We describe the fabrication of crystallographically preferred oriented TiO2 anatase nanotube arrays (p-NTAs) and the characterization of their photovoltaic properties. The preferred orientation to the (004) plane of the TiO2 nanotube array (NTA) was carefully controlled by adjusting the water content in the anodizing…
Nanostructured titania films are of growing interest due to their application in future photovoltaic technologies. Therefore, a lot of effort has been put into the controlled fabrication and tailoring of titania nanostructures. The controlled sol-gel synthesis of titania, in particular in combination with block copoly…
A series of zinc(II) coordination polymers with 5-methoxyisophthalate (CH3O–H2ip) and five related flexible N-donor ancillary ligands, [Zn(CH3O-ip)(bime)0.5] (1), [Zn(CH3O-ip)(btx)]2·H2O (2), [Zn(CH3O-ip)(bix)]2 (3), Zn(CH3O-ip)(bib) (4), [Zn2(CH3O-ip)2(bbim)]2 (5) [bime = 1,2-bis(imidazol-1′-yl)ethane, btx = 1,4-bis(…
Using a novel hemi-rigid ditopic ligand, naphthalene-1,5-diyldioxy-di-acetic acid (H2L), five metal(II)-complexes formulated as Mn(L)(DMF) (1), Cd(L)(H2O)2 (2), Pb(L)(DMF) (3), Cd(L)(phen) (phen = phenanthroline) (4) and Cd5(L)5(2,2′-bpy)2 (2,2′-bpy = 2,2′-bipyridine) (5) have been hydro(solvo)thermally synthesized an…
Hyaluronic acid-conjugated mesoporous silica nanoparticles (MSNs-HA) have been synthesized via a facile amidation reaction. This novel strategy can efficiently solve the agglomeration problem of MSNs in physiological fluids. The cellular experiments showed that MSNs-HA is capable of selectively targeting specific canc…
Within the background of biological nitrogen fixation mediated by the enzyme nitrogenase, transition-metal complexes capable of binding and activating dinitrogen towards protonation and reduction have been synthesised. Of particular interest in this research area has been the transition-metal mediated conversion of di…
Porous CdO–CdS core–shell nanoboxes with uniform morphology and good structural stability were facilely prepared by microwave-assisted in situ surface sulfidation of CdCO3 nanocubes followed by annealing treatment. The as-obtained products exhibit much higher visible-light-driven photocatalytic activity in the reducti…
We report a series of cobalt complexes with various polypyridyl ligands, where the oxidation potential is tuned from 0.17 to 0.34 V vs. ferrocene. The highest occupied molecular orbitals (HOMO) of the cobalt complexes were stabilized by adding electron acceptor groups on pyridyl or replacing pyridyl by pyrazole. These…
The final step in the preparation of ppp-DTS(PTTh222)222 involves end capping of the PT-DTS-PT core with 2-hexylbithiophene units via a microwave assisted Stille cross coupling reaction. Methyl transfer (instead of 2-hexylbithiophene transfer) can occur leading to the formation of (MePT)DTS(PTTh22). Although (MePT)DTS…
Nano-sized particles of manganese oxides have been prepared by a very simple and cheap process using a decomposing aqueous solution of manganese nitrate at 100 °C. Scanning electron microscopy, transmission electron microscopy and X-ray diffraction spectrometry have been used to characterize the phase and the morpholo…
Nanocomposites of functionalized reduced graphene oxide (FR-GO) nanosheets and a conducting polymer, poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS), were investigated for their applicability as stretchable transparent conducting electrode (TCE) materials. Adding FR-GO nanosheets functionalized by…
A V-shaped ligand bis(2-benzimidazol-2-ylmethyl)benzylamine L(1) with its two derivatives bis(N-methylbenzimidazol-2-ylmethyl)benzylamine L(2) and bis(N-benzylbenzimidazol-2-ylmethyl)benzylamine L(3) have been prepared. Reaction of these shape-specific designed ligands with Ag(pic) (pic = picrate) afforded three novel…
