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 (…
Synchrotron-based in situ X-ray near-edge absorption spectroscopy (XANES) has been used to study the valence state evolution of the vanadium ion for both the catholyte and anolyte in all-vanadium redox flow batteries (VRB) under realistic cycling conditions. The results indicate that, when using the widely used charge…
This article presents the interaction of curcumin in the microenvironments provided by aggregation of pluronic triblock copolymer P123 into micellar and vesicular assemblies. The formation of vesicles using triblock copolymer P123 and 5-methylsalicylic acid (5 mS) has been successfully characterized by optical spectro…
In this study, a three dimensional NiCrAl alloy foam was used as a current collector for high-power and high-capacity lithium iron phosphate batteries. A charge–discharge test revealed that at a high current rate, the electrode using a metal foam had better power performance and its capacity faded much less than in th…
A 3.6 × 10−2 M solution of a diglycolamide-functionalized task specific ionic liquid (DGA-TSIL) in [C4mim][NTf2] was used for the extraction of actinides (mainly Am) and other elements present in high level nuclear waste. The extraction of Eu3+ was relatively higher than that of Am3+ conforming to the mechanism displa…
Ge-rich ITQ-13 and ITQ-22 zeolites were degermanated by acid leaching of as-made—still containing organic template—and calcined forms. These two zeolites could be almost completely degermanated without modifying the framework structure. This behavior is different from IM-12 zeolite, which undergoes framework transform…
We introduce a type of Fresnel zone plate (FZP) in which its phase is shifted radially outward. This FZP can easily and precisely turn an incident plane wave into an annular beam at its focal plane. High efficiency and flexibility are the advantages of generating doughnut beams by this method. By performing direct cal…
Two enantiomorphic metal-organic frameworks with zeotype SOD topology have been successfully synthesized from enantiopure L-alanine and D-alanine, respectively, which demonstrates the feasibility of fabricating MOFs that integrate the 4-connected zeotype topologies and homochiral nature by the employment of enantiopur…
Finding a clear signature of topological superconductivity in transport experiments remains an outstanding challenge. In this work, we propose exploiting the unique properties of three-dimensional topological insulator nanowires to generate a normal-superconductor junction in the single-mode regime where an exactly qu…
This report describes the structural and electrochemical properties of the nanocomposite polymer electrolyte (70PEO:30AgI) incorporating SiO 2 filler of different weight percentage (wt %) ranging between 1 and 10 wt %. Studies on inorganic filler in polymer matrix may be quite familiar, but the chosen polymer, the eff…
