A novel non-hydrazine precursor solution followed by dip-coating has been developed to produce Cu2ZnSnS4 (CZTS) and Cu2ZnSn(S,Se)4 (CZTSSe) thin films. The precursor solution is based on an ethanol solution of metal–thioacetamide (TAA) complex with monoethanolamine (MEA) as the additive agent. By forming coordination…
Pt-based catalysts are widely used in fuel cells and sensors for their exceptional electrocatalytic activity. Among the different methods for producing Pt-based catalysts, chemical reduction is favorable, due to its scalability in volume production and versatility in realizing abundant chemical functionalization. In t…
Quantum dot sensitized solar cells (QDSSCs) present a promising technology for next generation photovoltaic cells, having exhibited a considerable leap in performance over the last few years. However, recombination processes occurring in parallel at the TiO(2)-QDs-electrolyte triple junction constitute one of the majo…
Existing phenol production mostly by cumene processes is a three-step route with unwanted acetone as by-product. Here, we report the FeCl3 and mesoporous carbon nitride hybrid (FeCl3/mpg-C3N4) as an active and selective photocatalyst to activate H2O2 for the oxidation of benzene to phenol under visible-light illuminat…
By using nonequilibrium Green's functions in combination with the density functional theory, we investigate the spin transport properties of manganese porphyrin-based spintronic devices constructed by two manganese porphyrin molecules connected with a p-phenylene-ethynylene group. The interesting spin filtering and ma…
New pH-activatable ratiometric fluorescent probes have been developed that have a coumarin structure attached to benzothiazole or indole units with one or two conjugated bonds. They have optical responses in acidic conditions. Probes with benzothiazole (1) and indole (2, 3) units have opposite responses to changes in…
A novel method for the preparation of highly mesoporous carbon materials (Kroll-Carbons; KCs) is described based on reactive carbochlorination etching of titania nanoparticles inside a dense carbon matrix leading to mesoporous carbons with precisely controllable porosity and high performance as cathode materials for l…
A unique nanocomposite C-TiO2 was prepared by the growth of TiO2 on carbon nanoparticles using a simple hydrothermal procedure. Transmission electron microscopic (TEM) measurements showed that the nanocomposites exhibited an average core diameter of approximately 5 nm with a rather well-defined lattice space (0.4 nm)…
The selenization of Cu-Zn-Sn-S nanocrystals is a promising route for the fabrication of low-cost thin film solar cells. However, the reaction pathway of this process is not completely understood. Here, the evolution of phase formation, grain size, and elemental distributions is investigated during the selenization of…
We demonstrate that the post-adsorption of small molecules (a phenothiazine-based dye) on the porphyrin-sensitized TiO2 anode surface plays dual roles: (1) to greatly retard the back reaction between conduction-band electrons in TiO2 and the oxidized species (I3−) in the electrolyte and (2) to enhance the spectral res…
Mesoporous aluminosilicates of the type Al-TUD-1, prepared via “green”, low-cost, non-surfactant templating routes, are effective and versatile heterogeneous acid catalysts for the production of useful bio-based furanic ethers and levulinate esters, via the reactions of the biorenewable substrates 5-hydroxymethyl-2-fu…
Owing to the lack of scalable high performance donor materials, studies on mass-produced organic photovoltaic (OPV) devices lag far behind that on lab-scale devices. In this work, we choose 6 already commercially available conjugated polymers and systematically investigate their potential in organic tandem solar cells…
A novel pillar[5]arene-based supramolecular polypseudorotaxane network constructed by orthogonal self-assembly has been successfully fabricated. The obtained supramolecular polypseudorotaxane polymer was formed by a combination of two different non-covalent interactions, quadruple hydrogen bonding and pillararene-base…
Fe3O4@C core-shell nanorings (R-Fe3O4@C) were fabricated by a synchronous reduction and carbon deposition process. As the anodes for lithium-ion batteries, these R-Fe3O4@C exhibit a high capacity, excellent cycling stability and good rate performance. This ring-shaped core-shell nanostructure design may pave the way t…
Tooth decay is one of the most common chronic disorders throughout the world. Regenerating decayed dentin/pulp structure requires the design of novel scaffolding materials that mimic the architecture of a natural dental extracellular matrix (ECM) and provide suitable environments for the attachment, proliferation, dif…
This article presents a smart strategy to successfully tackle two main limitations of organic solar cells (OSCs) in one step: the narrow absorption window of polymers as well as the Voc limitation related to the mono-PCBM. We demonstrate the high OSC performance of >5% in the combination of a fullerene multiadduct, i.…
Investigations on heterogeneous iron catalysis in the selective aerobic oxidation of a primary alcohol are presented. Continuous flow technology was used in combination with an iron oxide nanoparticle catalyst stabilized in a mesoporous aluminosilicate support (“flow nanocatalysis”) as a process intensification tool t…
SABRE hyperpolarizes substrates by polarization transfer from para-hydrogen in a metal complex. We have measured the signal enhancement of pyridine and its exchange rate in various [Ir(NHC)(Py)3(H)2](+) complexes to gain insight into their dependence on the N-Heterocyclic Carbene (NHC) ligand's steric and electronic p…
A low cytotoxicity and high efficiency delivery system with the advantages of low cost and facile fabrication is needed for the application of small interfering RNA (siRNA) delivery both in vitro and in vivo. For these prerequisites, cationic polymer-mesoporous silica nanoparticles (ssCP-MSNs) were prepared by surface…
A three-dimensional (3D) chiral mixed metal-organic framework [Cd4Cl(Ni-L)3(Ni-HL)(H2O)6(DMF)]·4DMF (CMOF 1) based on a new enantiopure dicarboxyl-functionalized Ni(saldpen) metalloligand Ni-H2L and a novel tetranuclear cadmium cluster [Cd4Cl(CO2)7(CO2H)] has been synthesized and characterized by elemental analyses, I…
