ICT fluorophore benzoxadiazole with its electron-donating group modified as a Cu(2+) chelator was conjugated with coumarin to construct a new ratiometric sensor with reversible intracellular Cu(2+) imaging ability.
TiO2 microspheres with a large surface area, high crystallinity, uniform nanostructure and good light scattering properties were synthesized in an acetone–phenol mixed solvent via a simple solvothermal process. X-ray diffraction patterns and electron microscopy images indicated that the prepared TiO2 microspheres had…
To explore the influence of different carboxylate ligands on the structures of metal–organic frameworks (MOFs), five novel Zn(II) coordination polymer compounds, namely, {[Zn(atz)(bia)]}n (1), {[Zn3(atz)3(tpa)3/2]}n (2), {[Zn2(atz)2(pda)]}n (3), {[Zn4(atz)2(btc)]·4H2O}n (4) and {[Zn2(atz)2(btec)]·H2O}n (5) have been s…
The carbon-based positive electrode of Lithium Air Batteries (LABs) is the component where the major competitive mechanisms occur, such as the electrochemical reactions leading to the formation and decomposition of multiple types of lithium oxides, lithium ion and electronic transport as well as oxygen transport. Thro…
D–π–A type boron dipyrromethene (BODIPY) dye YH-1, which has two pyridyl groups as electron-withdrawing-anchoring groups at the end of the 3- and 5-positions and a carbazole-diphenylamine moiety as an electron donor at the 8-position on the BODIPY core, was designed and developed as a photosensitizer for dye-sensitize…
The binding phase of cementitious materials, calcium–silicate–hydrates, can be described as nanogranular and as an inorganic hydrogel. Similar to other hydrated “soft matter,” the water confined within the nano- to microscale pores of such cementitious materials plays a crucial role in the structure and properties of…
Hollow 0.3Li(2)MnO(3)·0.7LiNi(0.5)Mn(0.5)O(2) microspheres are synthesized on a large scale through a simple in situ template-sacrificial route. Starting from porous MnO(2) microspheres, the hollow microspheres assembled with 0.3Li(2)MnO(3)·0.7LiNi(0.5)Mn(0.5)O(2) nanocrystals are formed by a nanoscale Kirkendall effe…
The effect of MFI zeolite nanosheet morphology and related mesostructures on the accessibility of acid sites evaluated from FTIR spectra of different adsorbed probe molecules and conversions and selectivities in toluene disproportionation and alkylation with isopropyl alcohol was investigated. Two-dimensional MFI lame…
Sophorolipids (SLs) are glycolipidic biosurfactants suitable for various biological and physicochemical applications. The nonedible Jatropha oil has been checked as the alternative raw material for SL synthesis using C. bombicola (ATCC22214). This is useful towards lowering the SL production cost. Through optimization…
Hierarchical mesoporous–macroporous MgO (HMMM) is successfully synthesized by using a facile calcination method. Mesoporous Mg(OH)2 produced from HMMM hydrolysis in uranium solution was used to remove U(VI) from aqueous solutions. TEM confirms that mesoporous Mg(OH)2 partly retains interconnected porous structure of H…
A new turn-on fluorescent chemosensor, DPPL1, was rationally designed and synthesized based on diketopyrrolopyrrole (DPP), which presented high sensitivity and selectivity for Zn(2+). Specifically, DPPL1 presented a large emission enhancement and a 70 nm blue-shift upon Zn(2+) binding. (1)H NMR titrations, studies int…
Three new 3D Mn(II)-MOFs have been synthesized via solvothermal reaction with MnCl2·4H2O and [1,1′:4′,1′′-terphenyl]-2′,4,4′′,5′-tetracarboxylic acid (H4tptc) in three different solvents [N-methyl-2-pyrrolidone (NMP), N,N-dimethylacetamide (DMA) and N,N-dimethylformamide (DMF)], namely, [Mn2(tptc)(H2O)(NMP)]·NMP (1),…
Advanced anode materials for next generation lithium ion batteries have attracted great interest due to the ever increasing demand for powerful, light-weight, and compact electrical devices. In this work, graphene nanosheets decorated with ultra-small Fe3O4 nanoparticles (USIO/G) were synthesized via a facile hydrothe…
Magnetite Fe3O4 has emerged as an important type of Li-storage electrode material for rechargeable battery applications. The engineering and synthesis of high-performance Fe3O4 with large capacity and stable cyclability via a facile approach is desirable but remains challenging. Here, we adopt a simple three-step meth…
A novel magnetically recoverable Pt nanoparticle catalyst was prepared by in situ NaBH4 reduction of a Pt4+ species bound to hydroxyl modified carbon-coated magnetic microparticles. The prepared ‘green’ catalyst allows for rapid and effective hydrogenation of aromatic nitro-compounds with excellent product yields as w…
A general approach for preparing enzyme-polymer nanoconjugates that respond to temperature in organic media is presented. These nanoconjugates readily dissolve in organic solvents for homogenous catalysis at 40 °C and showed greatly enhanced apparent catalytic activities. The recovery of the soluble enzyme-polymer nan…
Two new diketopyrrolopyrrole (DPP) based sensitizers (DPP-Br, DPPCN2) and a novel dyad DPP-NDI (NDI = naphthalene diimide) were synthesized and investigated for use in NiO p-type dye-sensitized solar cells (p-DSCs). The simple push-pull DPP-CN2 gives a promising photoconversion efficiency (PCE) of 0.07% with the iodid…
In this paper, mixed-solvent vapor annealing (M-SVA) was proposed to improve polymer crystallinity and inhibit fullerene intercalation into polymer side chains in a poly[N-9′-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)] (PCDTBT):[6,6]-phenyl-C71-butyric acid methyl ester (PC70BM)…
Density functional theory (DFT) calculations using the Perdew–Burke–Ernzerhof (PBE) exchange-correlation functional are presented for a 1 : 1 cocrystal formed by indomethacin and nicotinamide (IND-NIC) as well as for crystal structures of the individual components. DFT-D approaches which correct the DFT energy for dis…
