The present work is an experimental investigation of commercial diesel fuel liquid desulfurization via adsorption under mild conditions. The sorbent employed was a commercial high surface area activated carbon (AC), and studies involved both laboratory- and pilot-scale experiments performed in dedicated fixed-bed setu…
Abstract Ultrathin mesoporous NiCo2O4 nanosheets were directly grown on Ni foams to form an efficient and reversible anode for lithium‐ion half‐cell batteries. Nanosheets with wrinkles, which were monolayers of 10 nm NiCo2O4 nanoparticles, were interconnected to build up a honeycomb‐like architecture that offered a la…
Single nucleotide polymorphisms (SNPs) are frequently associated with various gene-related human diseases, whose determination has attracted great interest. Herein, we report a graphene oxide (GO) nanosheets-based fluorometric DNA biosensor to study the type and location of the single-base mismatch, as well as the inf…
Biochars (BC) generated from biomass residues have been recognized as effective sorbents for organic compounds. In this study, biochars as adsorbents for the removal of norfloxacin (NOR) from aqueous solutions were evaluated. Biochars were prepared from cassava dregs at 350 °C, 450 °C, 550 °C, 650 °C, and 750 °C, resp…
The Reststrahl spectral region of silicon carbide has recently attracted much attention owing to its potential for mid-infrared nanophotonic applications based on surface phonon polaritons (SPhPs). Studies of optical phonon resonances responsible for surface polariton formation, however, have so far been limited to li…
Hierarchical assembly of an oxo-bridged binuclear ZrOCo II light absorber unit coupled to a cuprous oxide nanocluster catalyst for CO 2 reduction on mesoporous silica support is demonstrated. The proper positioning of the Cu oxide cluster was achieved by photodeposition of a [Cu(NCCH 3 ) 4 ] 2+ precursor by visible li…
Magnetic excitations in the optimally doped high-${T}_{\mathrm{c}}$ superconductor ${\mathrm{Bi}}_{1.5}{\mathrm{Pb}}_{0.55}{\mathrm{Sr}}_{1.6}{\mathrm{La}}_{0.4}{\mathrm{CuO}}_{6+\ensuremath{\delta}}$ (OP-Bi2201, ${T}_{\mathrm{c}}\ensuremath{\simeq}34$ K) are investigated by Cu ${L}_{3}$ edge resonant inelastic x-ray…
We report on the use of an alkoxyamine (AA) for fabrication of functional micropatterns with complex structures by UV mask lithography. The living character of the polymer surface and the vertical spatial control of the repolymerization reaction from few tens of nanometers to few micrometers were demonstrated. The imp…
This study was undertaken to investigate the effectiveness of the hybrid adsorbent, which was synthesized from coal fly ash and was composed of lanthanum hydroxide and zeolite (La-ZFA), for phosphate removal from water. Long-term repeated adsorption tests for 30 days showed that the maximum removal capacity of the mat…
A global computer model has been developed for starve-fed nonconventional single-screw extrusion. The model has been built by combining a new melt conveying model with recently developed melting models. Mixing screw equipped with dispersive mixing element of Maddock has been considered as an example for modeling. Exte…
Enzyme I (EI) is the first component in the bacterial phosphotransferase system, a signal transduction pathway in which phosphoryl transfer through a series of bimolecular protein-protein interactions is coupled to sugar transport across the membrane. EI is a multidomain, 128-kDa homodimer that has been shown to exist…
Fenofibrate is one of the most commonly prescribed hyperlipidemia agents. Despite its high lipophilicity and ultralow aqueous solubility, most commercially available formulations use micronized crystalline fenofibrate form I, which has a low dissolution rate and poor oral bioavailability. Little is known about the cry…
N-Glycosylation is an important post-translational modification in most secreted and membrane-bound proteins in eukaryotic cells. However, the insect N-glycosylation pathway and the potentials contributing to the N-glycan synthesis are still unclear because most of the studies on these subjects have focused on mammals…
A series of cellulose ampholytes (CAms), with substitution degrees of cationic groups (DSC) of 0.41, 0.79, and 1.08, and with a substitution degree of anionic groups of 0.68, was prepared from sodium carboxymethylcellulose by a cationization reaction with 2,3-epoxypropyltrimethylammonium chloride. The obtained CAms we…
We demonstrate engineered selective absorption and subsequent selective thermal emission from sub-wavelength thickness optical structures at far-infrared (30–40 μm) wavelengths. Control over absorption/emission wavelength is demonstrated, with both polarization-dependent and -independent structures fabricated. Samples…
The performance of both large linear electron accelerators and smaller-scale ultrafast electron-diffraction setups is limited by the source of electrons, the photocathode. This study shows how a nonuniform surface of the source affects the energies of emitted electrons, using fundamental physics principles to guide th…
Abstract Using an analysis based on Marcus theory, we characterize losses in open-circuit voltage (VOC) due to changes in charge-transfer state energy, electronic coupling, and spatial density of charge-transfer states in a series of polymer/fullerene solar cells. We use a series of indacenodithiophene polymers and th…
We demonstrate a simple, low-cost, and green approach to deposit a microstructured coating on the silicone elastomer polydimethylsiloxane (PDMS) that can be coated with gold to produce highly stretchable and conductive films. The microstructured coating is fabricated using an aqueous emulsion of poly(vinyl acetate) (P…
Using the probabilistic language of conditional expectations, we reformulate the force matching method for coarse-graining of molecular systems as a projection onto spaces of coarse observables. A practical outcome of this probabilistic description is the link of the force matching method with thermodynamic integratio…
Critical current densities ( J c ) above 15 MA cm −2 have been achieved at 30 K, 2.5 T ( B || c ) in (Gd,Y)–Ba–Cu–O tapes with 20–25 mol.% Zr addition. The optimal compositions of Gd + Y, Ba + Zr and Cu to achieve lift factor in critical current above 6 at 30 K, 2.5 T ( B || c ) have been determined by development of…
