Acid-catalyzed hydrolysis of cellulose is a starting point for producing glucose-based fuels and chemicals. According to the mechanism of cellulose hydrolysis, hydrogen ions are responsible for the reaction. This study aims to elucidate the phenomena in cellulose hydrolysis at 180–220 °C using 5–20% (w/w) formic acid…
Converting poultry feather biomass into useful products presents a new avenue of utilization of agricultural waste material. However, not much is understood about the poultry feather structure or methods to process it. Fibers from non-traditional textile sources have the potential to offer novel properties at a reduce…
The growth of gold nanorods has been followed by small angle X-ray scattering and X-ray absorption. The synthesis is performed at high concentration of 3.5 mM in gold using in situ generation of seeds. It is shown that the growth occurs at constant number density of nanoparticles after the initial nucleation of seeds…
The facile phase-transfer of large, water-soluble metal nanoparticles to nonpolar solvent is reported here. Thiol-terminated polystyrene (PS-SH) is ligand-exchanged onto water-soluble metal nanoparticles in single-phase acetone/water mixtures, generating a precipitate. The solvent is then removed and the particles are…
The properties of sheet containing mechanically recycled postconsumer poly(L-lactic acid) bottle flakes blended with virgin poly(L-lactic acid) resin were assessed. Poly(L-lactic acid) bottles were flaked, cleaned, blended with virgin resin and then extruded and thermoformed into trays. The molecular weight, physical,…
Sorafenib-incoporated nanoparticles were prepared using a block copolymer that is composed of dextran and poly(DL-lactide-co-glycolide) [DexbLG] for antitumor drug delivery. Sorafenib-incorporated nanoparticles were prepared by a nanoprecipitation-dialysis method. Sorafenib-incorporated DexbLG nanoparticles were unifo…
Nanosized Mn 0.5 Zn 0.5 Fe 2 O 4 ferrite particles were synthesized by a reverse microemulsion reaction process. Core–shell nanocomposites composed of Mn 0.5 Zn 0.5 Fe 2 O 4 nanocrystals and conjugated polymer polyaniline were successfully synthesized from a simple and inexpensive process, and in situ chemical oxidati…
A new class of biocomposites based on oil palm empty fruit bunch fiber and poly(butylene adipate-co-terephthalate) (PBAT), which is a biodegradable aliphatic aromatic co-polyester, were prepared using melt blending technique. The composites were prepared at various fiber contents of 10, 20, 30, 40 and 50 wt% and chara…
We investigate the effect that the temperature dependence of the crystal structure of a two-dimensional organic charge-transfer salt has on the low-energy Hamiltonian representation of the electronic structure. For that, we determine the crystal structure of $\ensuremath{\kappa}$-(BEDT-TTF)${}_{2}$Cu${}_{2}$(CN)${}_{3…
Seven hybrid organic-inorganic bisphosphonate molybdenum(VI) polyoxometalate complexes with the general formula [(Mo(3)O(8))(4)(O(3)PC(C(m)H(2m)NRR'R″)(O)PO(3))(4)](8-) (m = 3; R, R', and R″ = H or CH(3)) and [(Mo(3)O(8))(2)(O)(O(3)PC(C(m)H(2m)NRR'R″)(O)PO(3))(2)](6-) (m = 3 or 4; R, R', and R″ = H or CH(3)) have been…
Abstract Zinc oxide (ZnO) films were grown by radio frequency magnetron sputter deposition and the changes to its surface composition and workfunction induced by argon sputter cleaning and oxygen plasma treatments were characterized using x-ray photoelectron spectroscopy, ultraviolet photoelectron spectroscopy and den…
The kinetics of Ni sorption to two Delaware agricultural soils were studied to quantitatively assess the relative importance of Ni adsorption on soil organic matter (SOM) and the formation of Ni layered double hydroxide (Ni-LDH) precipitates using both experimental studies and kinetic modeling. Batch sorption kinetic…
In this work we analyze the influence of random point defects introduced by 3 MeV proton irradiation on the critical current density (${J}_{c}$) and vortex dynamics of a Ba(Fe${}_{0.925}$Co${}_{0.075}$)${}_{2}$As${}_{2}$ single crystal. The results show that at low temperatures ($T$) the irradiation produces an enhanc…
The substitutional doping of Mo within VO 2 substantially alters the electronic and structural phase diagrams of the host lattice, most notably by bringing the technologically relevant metal–insulator phase transition temperature in closer proximity to room temperature. Here, we have used X-ray absorption fine structu…
We have contact! Material strain can have a dominating effect on contact electrification. When a deflated (relaxed) balloon is rubbed against teflon, the teflon surface charges positively, but when the same balloon is inflated (strained), the teflon surface charges negatively. This result illustrates that material str…
Abstract Conflicting results have been reported with respect to the photoinduced switching of the magnetic properties of [Fe III (salten)] + complexes [salten = 4‐azaheptamethylene‐1,7‐bis(salicylideneiminate)] coordinated by photoisomerizable ligands. In order to address this problem, two Fe III complexes [Fe(salten)…
In this paper, polymer nanocomposite films containing gold nanorods (AuNRs) and poly(2-vinyl pyridine) (P2VP) have been investigated for their structure-optical property relationship. Using transmission electron microscopy (TEM), the assembly of AuNRs (7.9 nm × 28.4 nm) grafted with a P2VP brush in P2VP films is exami…
The relationships between the molecular aggregation states and water repellency of the perfluoroalkyl ( R f ) groups of poly{2-(perfluorooctyl)ethyl acrylate} (poly(FA-C 8 )) brush thin films with broad and narrow molecular weight dispersities (MWDs) were analyzed by grazing incidence wide-angle X-ray diffraction (GI-…
We present a low-temperature (68–70 °C) synthesis of green light-emitting, trioctylphosphine oxide-capped magic-sized CdSe nanoclusters from the reaction of trioctylphosphine oxide–cadmium acetate precursors with trioctylphosphine selenide. We observed continuous growth of these magic-sized nanoclusters, which display…
We propose a direct method to determine absorption anisotropy of colloidal quantum rods. In this method, the rods are aligned in solution by using an alternating electric field and we measure simultaneously the resulting average change in absorption. We show that a frequency window for the electric field exists in whi…
