Biohybrid materials based on the intercalation of zein, the major storage protein in corn, into sodium-exchanged montmorillonite were prepared following two synthesis strategies. The first one made use of zein dissolved in 80% (v/v) ethanol/water solution, the usual solvent for this protein, while the second method is…
Bismuth oxygen selenide, Bi2O2Se, is a promising thermoelectric material because of its reduced thermal conductivity. In this study, we perform the first-principles calculation and utilize the solution of Boltzmann transport equation in a constant relaxation-time approximation to compute the electronic and thermoelect…
Summary Scale-inhibitor (SI) squeeze treatments are applied extensively for controlling scale formation during oil and gas production. The current research involves phosphonate/metal precipitate studies in the context of precipitation-squeeze treatments. The main focus here is on the precipitation and solubility behav…
Surface reactivity on metal oxide surfaces and its enhancement play important roles in heterogeneous catalytic reactions. In this work, the interactions of O 2 and H 2 O with reduced CeO 2 (111) surface are studied by density-functional theory calculations. The corresponding adsorption geometries, adsorption energies,…
The combination of synthetic and vegetable fibers in a polyester matrix can produce a hybrid material that may substitute pure glass composites depending on the application. Analysis of their dynamical mechanical properties is important, enabling a better understanding of the structure/property relationship. In this c…
A robust solution phase ligand exchange system for lead sulfide (PbS) quantum dots (QDs) in the presence of Pb-thiolate ligands is presented that can better preserve the excitonic absorption and emission features as compared to the conventional ligands. The photoluminescence after ligand exchange of PbS QDs with Pb-th…
Electrospun scaffolds of neat poly-ε-caprolactone (PCL), poly-ε-caprolactone/β-cyclodextrin inclusion complex (PCL/β-CD) and poly-ε-caprolactone amino derivative inclusion complex (PCL/β-CD-NH₂) were prepared by the electrospinning technique. The obtained mats were analyzed by a theoretical model using the Hartree⁻Foc…
ABSTRACT The effect of annealing poly(lactic acid) (PLA) and PLA grafted with itaconic anhydride (IA) at different temperatures was studied using differential scanning calorimetry (DSC) and wide angle X‐ray scattering (WAXS). For PLA, two crystal forms were obtained when annealed between 110 and 120 °C, transforming i…
One of the most challenging aspects of using nanofibrillated cellulose (NFC) for membranes production is their limited permeance. When NFC membranes are produced from aqueous suspensions, depending on their grammage, the permeances are in the range of a few decades of L/(hm 2 MPa) not matching satisfactory filtration…
This article examines the weldability of ductile cast iron when the root weld is applied with a tungsten inert gas (TIG) welding process employing an Inconel 625 source rod, and when the filler welds are applied with electrodes coated with 97.6% Ni. The welds were performed on ductile cast iron specimen test plates si…
Three-dimensional (3D) nanometal scaffolds have gained considerable attention recently because of their promising application in high-performance supercapacitors compared with plain metal foils. Here, a highly oriented nickel (Ni) nanowire array (NNA) film was prepared via a simple magnetic-field-driven aqueous soluti…
Novel biodegradable polymeric materials based on protein hydrolysate (Pr.Hyd), derived from waste products of the leather industry, and poly(ethylene glycol) diglycidyl ether (PEG) or epoxidized soybean oil (ESO) are obtained and their physico‐chemical properties and mechanical behaviour are evaluated. Different proce…
Abstract We synthesized an ultrapure nano-polycrystalline diamond (NPD) containing very few chemical impurities (<1 ppm). The 13 C concentration of the carbon source was reduced to less than 0.01% by using 12 C-enriched high-purity carbon. The ultrapure NPD was synthesized by direct conversion from graphite under h…
ABSTRACT Ethyl vinyl acetate (EVA) copolymers are recyclable plastics with exceptional biocompatibility, thus they are potent candidate materials for biomedical applications. In this study, improvement in the EVA biostability was aimed by the incorporation of hybrid nanofillers. EVA copolymer incorporating 3 wt % orga…
Lithographically fabricated MoS2 field effect transistors suffer from several critical imperfections, including low sub-threshold swings, large turn-on gate voltages (VT), and wide device-to-device variability. The large magnitude and variability of VT stems from unclean interfaces, trapped charges in the underlying s…
In a typical colloidal CdSe nanocrystal more than 50% of the atoms are located at the surface. These atoms can give rise to electronic traps that can deteriorate the performance of optoelectronic devices made of these nanomaterials. A key challenge in this field is thus to understand with atomistic detail the chemical…
Superdipolar glass properties of polar nanoregions (PNRs) in relaxor ferroelectric $\mathrm{PbM}{\mathrm{g}}_{1/3}\mathrm{N}{\mathrm{b}}_{2/3}{\mathrm{O}}_{3}$ (PMN) are compared to those of ferromagnetic nanoparticles (FNPs) in the superspin glass ${[\mathrm{C}{\mathrm{o}}_{80}\mathrm{F}{\mathrm{e}}_{20}(0.9\phantom{…
Motivated by recently discovered quasi-one-dimensional superconductor ${\mathrm{K}}_{2}{\mathrm{Cr}}_{3}{\mathrm{As}}_{3}$ with ${D}_{3h}$ lattice symmetry, we study a one-dimensional three-orbital Hubbard model with generic electron repulsive interaction described by intraorbital repulsion $U$, interorbital repulsion…
Well-defined mesoporous carbon/poly(glycidyl methacrylate) (PGMA) hybrids were prepared by surface-initiated atom transfer radical polymerization (SI-ATRP) from mesoporous carbons with different steric configurations and structural properties. In the initial step, a robust polydopamine (PDA) layer was deposited on the…
Fe 2+ plays an essential role for artemisinin (ART)-based drugs in anticancer therapy. As a result, it is important to realize these two agents’ cotransport for improving antitumor efficacy. We utilized a kind of alternating magnetic field (AMF) and tumor-responsive material—mesoporous Fe 3 O 4 (mFe 3 O 4 )—to encapsu…
