Interactions between biomass constituents (cellulose, hemicelluloses, and lignin) under pyrolytic conditions have received more and more attention in recent years. A synthesized sample was prepared through mixing of cellulose and lignin with a mass:mass ratio of 1:1. The cellulose-lignin mixture (C-L-M) was heated fro…
In this study, the effects of pH on shear thickening behaviors were investigated based on concentrated dispersions consisting of polystyrene-ethylacrylate (PSt-EA) copolymer nanospheres. The pH values of the above shear thickening fluids were controlled by adding different kinds of acid and alkali solutions, and the r…
The role of endocellulases and endoxylanase during liquefaction and saccharification of hydrothermally pretreated wheat straw was studied. The use of a flow-loop setup with in-line magnetic resonance imaging enabled frequent measurements of viscosity at 55°C during saccharification at 6% total solids content. Viscosit…
Modern scleractinian coral skeletons are commonly composed of aragonite, the orthorhombic form of CaCO3. Under certain conditions, modern corals produce calcite as a secondary precipitate to fill pore space. However, coral construction of primary skeletons from calcite has yet to be demonstrated. We report a calcitic…
In this letter, the facial noncovalent adsorption of single-stranded DNA (ssDNA) provided single-walled carbon nanotubes (SWNTs) with biofunctionality while their superior properties were retained. In this case, we innovatively demonstrated the feasibility of employing the negative surface charge of ssDNA-SWNTs to rea…
A B S T R A C T The present study was aimed at evaluating the mechanical properties of Aluminium 2024 alloy reinforced with B4C. An effort is made to enhance the mechanical properties like tensile strength and hardness of AMCs by reinforcing 2024 Al matrix with B4C particles. By stir casting method, aluminium matrix w…
Recent large price reductions with wafer-based cells have increased the difficulty of dislodging silicon solar cell technology from its dominant market position. With market leaders expected to be manufacturing modules above 16% efficiency at $0.36/Watt by 2017, even the cost per unit area ($60-$70/m2) will be difficu…
A new facile chemical approach has been developed to produce cuboid-shaped TiO 2 nanocrystals with high-energy facets {001} under stream-assisted ionothermal method. The structural features, crystallinity, purity, mesophase, and morphology of the nanostructured TiO 2 were investigated by powder X–ray diffraction, high…
Stable quasi-solid-state dye-sensitized solar cells (DSCs) were fabricated by using room-temperature molten salts (1-methyl-3-hexyl-imidazolium iodide), and a series of diamine derivatives with different lengths of alkyl chain as low molecular mass organogelators (LMOGs). The number of methylene (−CH 2 −) units betwee…
At the synapse, D-serine is an endogenous co-agonist for the N-methyl-D-aspartate receptor (NMDAR). It plays an important role in synaptic transmission and plasticity and has also been linked to several pathological diseases such as schizophrenia and Huntington's. The quantification of local changes in D-serine concen…
Abstract Mixed‐matrix membranes (MMMs) consisting of ethyl cellulose as continuous matrix and inorganic particle C60 as dispersed phase were prepared for propylene/propane separation. The impact of the C60 content on the separation properties of MMMs without and with ultraviolet cross‐linking was investigated. The inc…
We report a joint theoretical and experimental investigation on the effect of TiO 2 protonation on the interfacial electronic coupling and injection rates in organic dye-sensitized solar cells (DSCs). We model the electronic structure of different organic dye-sensitized TiO 2 cluster models at different degrees of sur…
Abstract Metal nanowires supporting propagating surface plasmons (SPs) can be used as nanowaveguides and nanoantennas for light manipulation beyond the diffraction limit. Here the control of the propagation and radiation of SPs on silver nanowires is investigated. By covering an Al2O3 layer onto a silver nanowire to c…
A C60 Prato derivative with bis-(t)Bu ester was prepared as a stable and convenient scaffold for the development of fullerene derivatives such as water-soluble C60-PEG conjugates, fulleropeptides via solid phase synthesis, and bis-functionalized C60.
In this work, we have synthesized two different phases of CdS nanoparticles, CdS/TiO2 composites and their supported form on ZSM-5 type metalosilicates (ferrisilicate and aluminosilicate) as CdS–TiO2/metalosilicate composites. The photocatalytic performance of these samples was evaluated by monitoring the amount of hy…
Golden single-walled carbon nanotubes (SWNTs) were prepared by growing gold nanoparticles onto the bilayer polysaccharide functionalized SWNTs. The layer-by-layer self-assembly of sodium alginate and chitosan on SWNTs provided an ideal surface with high density of active metal-binding groups such as amino and carboxyl…
This report investigates the impact of droplet temperature on the head-on collision of binary droplets on a superhydrophobic surface. Understanding droplet collision is critical to many fundamental processes and industrial applications. There are many factors, including collision speed, collision angle, and droplet co…
Twinning induced plasticity (TWIP) steels with excellent strength and elongation properties are expected to be the next generation of automotive high-strength steels. The present work investigates endogenous inclusions formed in Fe–25Mn–3Si–3Al TWIP steels in laboratorial ingot, mold casting after AOD steelmaking and…
Cu-poor Cu2− x SnS3 (CTS) powders with x = 0.0–0.3 prepared by mixing the elemental powders and post-heating at 600 °C in N2 gas were analyzed by X-ray diffraction and ultraviolet–visible–near-infrared (UV–vis–NIR) spectroscopy. The area of the solid solution region in the Cu-poor side of CTS was quite small in the Cu…
Current theoretical studies of electronic correlations in transition metal oxides typically only account for the local repulsion between d -electrons even if oxygen ligand p -states are an explicit part of the effective Hamiltonian. Interatomic interactions such as between d - and (ligand) p -electrons, as well as the…
