Here, I address the topic of suitability for redox research of common settings in cell cultures. This is done through the prism of in vitro anticancer effects of vitamin C. Cell culture media show lower concentrations of iron and a higher level of oxygen compared to interstitial fluid. Such a setup promotes ascorbate-…
Abstract Mechanically alloyed Al⋅Mg powders with the mole fraction of Al varied from 0.47 to 0.9 were burned at atmospheric pressure in water vapor. The powders were carried by nitrogen through the center of a hydrogen‐oxygen diffusion flame. The particles ignited in the steam at approximately 2500 K, generated as the…
A tight-binding potential model which goes beyond the Slater-Koster two-center approximation and includes explicit three-center and crystal field expressions is presented. Using carbon and silicon as examples, we show that various bulk structures, surface reconstructions, and the structures of clusters and liquids of…
ABSTRACT Durable excellent hydrophobic surface on cellulose substrate was fabricated from the silica hydrosol functionalized with silane chemicals by a facile electrochemically assisted deposition technique. The silica hydrosol was synthesized using tetraethoxysilane (TEOS) as the precursor and sodium dodecylbenzene (…
Using finite difference time domain (FDTD) method, we numerically investigate one-dimensional photonic crystals (1D PCs) with [Formula: see text] structure, where [Formula: see text] and [Formula: see text] stand for different dielectric materials, and [Formula: see text] the graded-index (GRIN) material. The transmis…
Fiber Bragg grating sensors are placed in a fiber-optic Sagnac loop to combine the grating temperature sensors and the fiber-optic mandrel acoustic emission sensors in single optical circuit. A wavelength-scanning fiber-optic laser is used as a common light source for both sensors. A fiber-optic attenuator is placed a…
The red-shift on fluorescent dyes spectra at high concentration was investigated by laser induce fluorescence technique. In this research, the fluorescent dyes (Rhodamine 6G, Rhodamine B, Fluorescein and Bromofluorescein) were used. The sample solutions were prepared with methanol solvent in the concentration range of…

The translocation of polymers through a small pore into crowded media with dynamic attractive nanoparticles is simulated. Results show that the nanoparticles at the trans side can affect the translocation by influencing the free-energy landscape and the diffusion of polymers. Thus the translocation time τ is dependent…
We report a design method based on multiple-faceted refractors for free-form illumination of a refractive surface. The free-form surface is constructed as a set of primitive surface elements, which provide flexibility to satisfy the requirements of practical design problems. An extended light source can be considered,…
We report a novel concept of graphene transistors on Scotch tape for use in ubiquitous electronic systems. Unlike common plastic substrates such as polyimide and polyethylene terephthalate, the Scotch tape substrate is easily attached onto various objects such as banknotes, curved surfaces, and human skin, which impli…
Abstract New 4′-( N -alkylpyrrol-2-yl)-2,2′:6′,2″-terpyridines were synthesized by N -alkylation of a pyrrole substituent with alkyl halides in dimethyl sulfoxide.
The exploration of the composition space diagram of the FeF 3 /ZnF 2 –H amtetraz -HF aq system (H amtetraz = 5-aminotetrazole) by solvothermal synthesis at 160 °C for 72 h in dimethylformamide (DMF) has evidenced five new hybrid fluorides ( 1 – 5 ); the structures are characterized from single crystal X-ray diffractio…
Abstract The oxygen reduction reaction (ORR) is a crucial process not only in fuel cells, but also in metal–air batteries, thus its electrocatalysts have attracted considerable attention. Here, we report the use of a vanadium nitride/porous graphitic nanocarbon (VN/PGNC) composite as an efficient support for a platinu…
Abstract In recent years, the partitioning of food and pharmaceutical materials in ionic liquid-based aqueous two-phase systems (ATPSs) has attracted the attention of researchers to itself as a new approach. A new type of these aqueous two-phase systems is based on cholinium chloride. Cholinium chloride is a type of v…
In an effort to explore the effect of ancillary ligands on the spectral properties and overall G-quadruplex DNA binding behavior, two new ruthenium(II) complexes [Ru(phen)2 (dppzi)](2+) (1) and [Ru(dmp)2 (dppzi)](2+) (2) (phen=1,10-phenanthroline, dmp=2,9-dimethyl-1,10-phenanthroline, dppzi=dipyrido[3,2-a:2',3'-c]phen…
PURPOSE: The aim of the present study is to investigate the effects of biological agents (BAs) on human chondrocytes and osteocytes in vitro. METHODS: Primary cell cultures obtained from gonarthrosis patients were divided into four groups, two of which were designated as control cultures of chondrocyte and osteocyte,…
The rapid evaporation and explosive boiling of a van der Waals (vdW) liquid drop in microgravity is simulated numerically in two-space dimensions using the method of smoothed particle hydrodynamics. The numerical approach is fully adaptive and incorporates the effects of surface tension, latent heat, mass transfer acr…
Silicon oxynitride thin films were synthesized by reactive high power impulse magnetron sputtering of silicon in argon/nitrous oxide plasmas. Nitrous oxide was employed as a single-source precursor supplying oxygen and nitrogen for the film growth. The films were characterized by elastic recoil detection analysis, x-r…
The separation of methane/ethylene gas mixtures by the adsorption–hydration method was investigated by using a wet zeolitic imidazolate framework (ZIF) microporous material, ZIF-8. The influences of the initial gas–solid ratio (the volume ratio of gas mixture to ZIF-8) and water content of wet ZIF-8 on the separation…
