An algal biofilm was employed as a novel kind of adsorbing material to remove Zn(II) from simulated wastewater. The algal biofilm system formed by Oedogonium sp. was operated in a dynamic mode for a period of 14 days with an initial Zn(II) concentration of 10 mg/L. The average effluent Zn(II) concentration was 0.247 m…
This study investigates nonisothermal co-drying kinetics of two typical biomasses (cornstalk and red pine) with lignite in the presence of a nitrogen atmosphere using a thermal gravimetric analysis technique. The drying rate can be increased by either decreasing the blending ratio of biomass or increasing the heating…
In this paper, a simple hydrothermal method was designed for the selective synthesis of Eu-doped tetragonal DyPO4 and hexagonal DyPO4·1.5H2O nanocrystals. It was found that the hydrothermal conditions (temperature and pH) and organic additive are very important in determining the crystal structures and morphology of t…
Purpose: To use endogenous myrosinase in Carica papaya seed to convert benzyl glucosinolate (BG) to benzyl isothiocyanate (BITC) and then extract it for further studies.Methods: Process variables including seed powder particle size, sample-to-solvent ratio, pH of buffer solution, enzymolysis temperature, enzymolysis t…
We developed biodegradable nanofibrous polylactide/chitosan membranes for the filtration of heavy metal ions. Polylactide and chitosan were first separately dissolved in trifluoroacetic acid. The solutions were then mixed and electrospun into nanofibrous membranes via an electrospinning process. The morphology of the…
A direct one-step and low temperature micro-fabrication process, enabling to realize large area totally inorganic TiO2 micro-patterns from a spin-on resist, is presented. High refractive index structures (up to 2 at 632 nm) without the need for transfer processes have been obtained by mask assisted UV lithography, exp…
Abstract The formation of sulfate and carbonate salts of barium and calcium during oil production and stimulation operations can result in blocked pore throats in the near wellbore region, narrowed production tubing, deposits on equipment, and in more serious cases, formation damage. Polymeric scale inhibitors are com…
The development of smart delivery systems able to deliver and target a drug to the site of action is one of the major challenges in the field of pharmaceutical technology. The surface modification of nanocarriers, such as liposomes, is widely investigated either for increasing the blood circulation time (by pegylation…
The DraR/DraK two-component system was found to be involved in the differential regulation of antibiotic biosynthesis in a medium-dependent manner; however, its function and signaling and sensing mechanisms remain unclear. Here, we describe the solution structure of the extracellular sensor domain of DraK and suggest…
The spatial and temporal scales of hot particle thermalization in inorganic scintillators are critical factors determining the extent of second- and third-order nonlinear quenching in regions with high densities of electron-hole pairs, which, in turn, leads to the light yield nonproportionality observed, to some degre…
We use the scalar relativistic ionized equation-of-motion coupled-cluster approaches, correlating valence and semi-core electrons and including up to 3-hole-2-particle terms in the ionizing operator, to investigate the photoelectron spectrum of \documentclass[12pt]{minimal}\begin{document}${\rm Au}_{3}^{-}$\end{docume…
The first Re(I)–bithiazole complexes are structurally reported. Complexes with the general formula fac -[ReL(CO) 3 Cl] have been designed and prepared successfully, where the bidentate chelating ligand L is one of a family of linear bithiazole based aromatic heterocyclic fluorescent compounds bearing different donor/a…
The synthesis and magnetic characterisation of a new series of 1D {Mn2IIILn2III}n (Ln = Pr, Nd, Gd, Tb, Dy) coordination polymers are described. The repeating unit consists of a tetranuclear fragment made up of two MnIII and two LnIII ions exhibiting a butterfly/planar-diamond motif. The MnIII ions are situated in the…
We deposit a paramagnetic pyrene derivative of the nitronyl nitroxide radical on Si(111). The molecules experience a strong chemical interaction with the substrate that influences the film growth. We also study the time evolution of the nitronyl nitroxide radical under a micro-focused soft X-ray beam, observing a stab…
We report a rapid and simple assay for colorimetric visualization of thrombin at nanomolar levels using functional gold nanoparticles (FAuNPs) coupled with microporous membranes. We used a 29-mer thiolated-thrombin-binding-aptamer (TBA29) to prepare TBA29 functionalized AuNPs (TBA29-AuNPs) for the selective detection…
Ultrasensitive surface enhanced Raman scattering substrates have been fabricated by electrodepositing Au nanoparticles onto porous gallium nitride. A detection limit of ∼10−16 M rhodamine 6G, approximating single-molecule detection, can be achieved.
This study compared and characterized slicewood acetylation with acetic anhydride using conventional liquid phase, microwave, and vapor phase reactions. The results revealed that there were no significant differences in the flexural properties between the unmodified and acetylated slicewood, regardless of the reaction…
In this work, nano-sized spherical MnO2 particles with large surface area were synthesized employing spray pyrolysis for application in a Zn/MnO2 primary cell. Furthermore, we experimentally investigated the performance of nano-sized MnO2 particles when mixed with conductive additives, such as graphite and Vulcan carb…
The influence of sunlight of varying intensity on the performance of UNS S30400 stainless steel (SS) was explored under conditions of natural biofilm development in coastal seawater. In a series of tests performed outdoors under an opaque roof, a range of shades were fashioned to impart varied amounts of diurnal light…
We have observed a magnetic vortex lattice (VL) in ${\mathrm{BaFe}}_{2}({\mathrm{As}}_{0.67}{\mathrm{P}}_{0.33}){}_{2}$ (BFAP) single crystals by small-angle neutron scattering. With the field along the $c$ axis, a nearly isotropic hexagonal VL was formed in the field range from 1 to 16 T, and no symmetry changes in t…
