Protein adsorption from (aqueous) solutions onto a (solid) surface is a common process that takes place at biological interfaces. This phenomenon, that spontaneously occurs, changes the properties of the surface and can induce structural modifications on proteins. Proteins in solution can be easily identified/quantifi…
An important goal in the development of highly functional organic materials is to design self-assembling molecules that can reproducibly display chemical signals across length scales. Within the biomedical field, biomolecules are highly attractive candidates to serve as bioactive building blocks for the next generatio…
Electrospinning is one of the most versatile and effective tools to produce nanostructured fibers in the biomedical science fields. The nanofibrous structure with diameters from tens to hundreds of nanometers largely mimics the native extracellular matrix (ECM) of many tissues. Thus far, a range of compositions includ…
The photochromic [2.2]paracyclophane-bridged imidazole dimers show instantaneous coloration upon exposure to UV light and rapid fading in the dark. A new [2.2]paracyclophane-bridged imidazole dimer, pseudogem-PPI-DPI[2.2]PC, with high photosensitivity to UVA radiation was developed. To enhance the photosensitivity, we…
We report novel surfactants that can be used for the separation of metallic (M) and semiconducting (S) single-wall carbon nanotubes (SWCNTs). Among the M/S separation methods using surfactants in an aqueous solution, sodium dodecyl sulfate plays a key role in density gradient ultracentrifugation (DGU) and agarose gel…
Intensive aquaculture releases large quantities of nutrients into aquatic bodies, which can lead to eutrophication. The objective of this study was the development of a biological recirculatory wastewater treatment system with a diazotrophic cyanobacterium, Aulosira fertilissima, and simultaneous production of valuabl…
Melting point phenomena of micron-sized indium particles embedded in an aluminum matrix were studied by means of acoustic emission. The acoustic energy measured during melting increased with indium content. Acoustic emission during the melting transformation suggests a dislocation generation mechanism to accommodate t…
We show within a local self-consistent mean-field treatment that a random distribution of magnetic adatoms can open a robust gap in the electronic spectrum of graphene. The electronic gap results from the interplay between the nature of the graphene sublattice structure and the exchange interaction between adatoms.The…
The unique combination of high surface area, high electrical conductivity and robust mechanical integrity has attracted great interest in the use of graphene sheets for future electronics applications. Their potential applications for high-power energy storage devices, however, are restricted by the accessible volume,…
The microscope characters of flame-retardant PC/ABS by a new kind of phosphate flame retardant, bisphenol-a bis (dipenyl phosphate) (BDP), is carried out in this paper using Scanning Electron Microscope (SEM). The result shows that flame retardant and unflame retardant materials before combustion and after indicate th…
Mg(NH2)2 was synthesized by first high energy milling MgH2 powder in a 99.995% NH3 atmosphere and then heat treating at 300oC, and hydrogen storage properties of prepared Mg(NH2)2+2.2LiH (molar ratio) had been studied in the temperature range of 150-240oC. It was found that mechanical milling of Mg (NH2)2 and LiH with…
The enhancement of alkaline industrial wastes on the desulfurization performance and utilization of limestone has already been found. In order to explore the reason of this phenomenon from the kinetic point of view, two typical alkaline wastes, carbide slag with a high calcium content and Bayer process red mud with mo…
The most commonly used Micro tubular solid oxide fuel cell (MT-SOFC) anode material is a two phase nickel and yttria stabilized zirconia (Ni/YSZ) cermet. And the mechanical stability of anode support layer, in anode-supported electrolyte designs, is very important for large scale applications. During the assembly of s…
Palygorskite supported manganese oxide catalysts (MnOx/PG) were prepared for lower temperature selective catalytic reduction (SCR) of NOx by NH 3 . Catalyst’s SCR activity was estimated at varied temperatures. Catalyst’s properties were characterized by XRD, NH 3 adsorption and TPD. Results showed that MnOx/PG catalys…
The dielectric properties and electrical conductivity of the ferroelectric perovskite solid solutions Li 0.07 Na 0.93 Ta 0.1 Nb 0.9 O 3 and Li 0.07 Na 0.93 Ta 0.111 Nb 0.889 O 3 have been studied at temperatures from 290 to 700 K and frequencies from 25 Hz to 1 MHz. In this temperature range, the solid solutions under…
Abstract Heterogen katalysierte Gasphasenreaktionen bei hohen Temperaturen werden seit langem bei Energieumwandlungsprozessen eingesetzt, um effizient chemische Energieträger in Wärme, Strom und wertvollere chemische Energieträger zu wandeln. Aufgrund der hohen Temperaturen und kurzen Verweilzeiten sind die verwendete…
The mechanical properties, thermal behaviors and morphology of poly(butylene succinate) (PBS)/microcrystalline cellulose (MCC) composites were investigated. The MCC used in this study was prepared by hydrolyzing cotton fabric waste with 2.5 N hydrochloric acid at 100°C for 30 min. PBS was melt mixed with three loading…
Titanium-doped zinc orthosilicate (α-Zn 2 SiO 4 :Ti) phosphor thin films were deposited on silicon wafer substrates by the sol–gel process. The crystallization processes and photoluminescence properties of the films were investigated. X-ray diffraction revealed that the dried films were amorphous and converted into si…
Molecular dynamics of glibenclamide and glimepiride in their glassy state were studied by means of broadband dielectric spectroscopy. In both compounds we found a γ-relaxation process, with nearly the same value of activation energy. Further, we were able to identify the origin of γ relaxation by performing calculatio…
A range of stainless steels has been investigated for resistance to microbiologically influenced corrosion in seawater. The corrosion potential was monitored for stainless steel coupons exposed to sterilized seawater and to microbiologically active seawater, which showed the effect of the growth of microorganisms. Cyc…
