Highly-flexible, ITO-free dye-sensitized solar cells (DSSCs) are fabricated in a simple, all-solution-based, facile, and controllable way. A double mesh structure is applied to DSSCs, and the design principles, especially scale parameters, are analyzed delicately to ensure the power conversion efficiency and mechanica…
The effects of exohedral moieties and endohedral metal clusters on the isomerization of M3N@I(h)-C80 products from the Prato reaction through [1,5]-sigmatropic rearrangement were systematically investigated by using three types of fulleropyrrolidine derivatives and four different endohedral metal clusters. As a result…
Structures and transport behaviors around the ionomer–catalyst interface in polymer electrolyte membrane fuel cells (PEMFCs) have aroused great research interests in recent years. Herein, classical molecular dynamics simulation method is used to investigate the interfacial self-assembly phenomena of three fully hydrat…
A series of soluble squaraine derivatives has been designed and developed as a donor material for solution-processible organic photovoltaic cells. In combination with [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) as an acceptor, we obtained a power conversion efficiency of 4.86% from bulk-heterojunction photovol…
This paper reports a simplified and compact mechanical scheme designed for providing alternatively high flux or high spectral resolution from a monochromator for the 2 - 14 keV X-ray range in a stationary spot at a sample. The example case treats a bending magnet source at the Elettra storage ring. The properties of t…
Amyloid peptides are considered to be the main contributor for the membrane disruption related to the pathogenesis of degenerative diseases. The variation of amino acids at the carboxylic terminus of amyloid peptide has revealed significant effects on the modulation of abnormal assemblies of amyloid peptides. In this…
We compare six lithium potentials by examining their ability to predict coexistence properties and liquid structure using molecular dynamics. All potentials are of the embedded-atom method type. The coexistence properties we focus on are the melting curve, vapor pressure, saturated liquid density, and vapor-liquid sur…
Herein, we report the synthesis of a nitrogen-doped graphene (NGr) interpenetrated 3D Ni-nanocage (Ni-NGr) electrocatalyst by a simple water-in-oil (w/o) emulsion technique for oxidation of water to dioxygen. Correlation of adsorption of NGr and subsequent interpenetration through the specific surface plane of nickel…
ZnO/ZnSxSe1−x core–shell nanowire arrays on a silicon substrate were successfully prepared via a hydrothermal method followed by chemical vapor deposition (CVD) of the ZnSxSe1−x shell. By optimizing the CVD growth conditions, a crystalline ZnSxSe1−x shell and well-aligned ZnO/ZnSxSe1−x interface were achieved, which p…
In Europe, because of the high production levels of livestock farming in general and pig farming in particular, animal waste management has become increasingly important to comply with the required lowering of livestock farming environmental pressure. Usually manures undergo solid/liquid separation, which generates on…
Mesoporous anatase TiO2 sheets/rGO sandwich-like nanocomposites were facile synthesized by acid-assisted tetrabutyl titanate hydrolysis and subsequent thermal reduction process. Structural, morphological, and compositional properties were characterized by various techniques, such as X-ray diffraction, scanning electro…
We study polarization independent improved light trapping in commercial thin film hydrogenated amorphous silicon (a-Si:H) solar photovoltaic cells using a three-dimensional silver array of multi-resonant nano-disk structures embedded in a silicon nitride anti-reflection coating to enhance optical absorption in the int…
A stochastic analytical model developed for nucleation in a nanoscale phase and applied to vapor-liquid-solid growth agrees with earlier numerical simulations while providing significantly more information about parameters influencing nucleation. Future experiments may test the predictions made and lead to enhanced co…
Through the incorporation of triethylene glycol (TEG) units into platinum(II) bzimpy complexes and by various spectroscopic and microscopy studies, an unusual thermo-responsive behaviour, which is distinct from those of other ethylene glycol–pendant compounds, was observed. The unprecedented existence of the large hys…
Four outcrops of Lower Cretaceous (Barremian) karst bauxites located in Teruel (NE Spain) were analysed to determine their mineral associations and genesis related to climatic palaeoweathering events and late superimposed kaolinization processes. The materials comprise metric-sized pisolitic blocks embedded in a clay-…
The aromatization of methanol over parent HZSM-5 and the modified NiO-HZSM-5 in a fixed-bed reactor was investigated under CO2 and N2 flow. The as-prepared catalysts were characterized by H2-TPR, XRD, BET, NH3-TPD, CO2-TPD and probe-molecule reaction. Compared with parent HZSM-5 in CO2 or N2 flow and with NiO-HZSM-5 i…
Phytostabilization of heavy metals in contaminated soils should be subject to two conditions, the first is the choice plant must be able to stabilize heavy metals in soil, the second is the plant material which produced from the phytostabilization process must be safe and useful to avoid overload on environmental syst…
An extension of the GROMOS 53A6GLYC force field for carbohydrates to encompass glycoprotein linkages is presented. The set includes new atomic charges and incorporates adequate torsional potential parameters for N-, S-, C-, P-, and O-glycosydic linkages, offering compatibility with the GROMOS force field family for pr…
A novel polymer is developed and used as underlying interlayer to improve donor polymer/acceptor material blend morphology of active layer in polymer solar cells (PSCs). The polymer poly{ N -9-[1,17-bis(diethylphosphonate)heptadecanyl]-2,7-carbazole- alt -5,5-(4,7-di-2-thienyl-2,1,3-benzothiadiazole)} (PCDTBT-Pho) is…
Conversion electrodes, the materials of choice for the next generation lithium-ion battery (LIB), are mainly limited to metal oxides. In this work, we have investigated the electrochemical performance of chemically synthesized Cu(OH)2 nanoflower arrays. A 50 : 50 composite of Cu(OH)2 and multiwalled carbon nanotubes (…
