Impure tricalcium silicate (C3S) in portland cement may contain various foreign ions. These ions can stabilize different polymorphs of C3S at room temperature and may affect its reactivity. In this paper, the effects of magnesium and zinc on the polymorph ...
The toxicity of silver nanoparticles (AgNP) to aquatic organisms, including zebrafish (Danio rerio), has been demonstrated, but differing opinions exist on the contribution of the physical properties of the particles themselves and the free dissolved silve ...
Fluorescent sensors are valuable tools for investigating the biochem. of metal cations, notably calcium and zinc. Most probes rely on quenching of photoinduced electron transfer as a fluorescence turn-on mechanism. The information that can be obtained from ...
NEMS (Nanoelectromechanical Devices) have been of particular interest in recent years due to a growing set of new applications they offer in domains such as sensitive charge detection, mass sensing and biological imaging. Their size, being reduced down to ...
Phytoextraction with somaclonal variants of tobacco and sunflower mutant lines (non-GMs) with enhanced metal uptake and tolerance can be a sustainable alternative to conventional destructive decontamination methods, especially for stripping bioavailable zi ...
The first near-IR fluorescent turn-on sensor for the detection of nitroxyl (HNO), the one-electron reduced form of nitric oxide (NO), is reported. The new copper-based probe, CuDHX1, contains a dihydroxanthene (DHX) fluorophore and a cyclam deriv. as a Cu( ...
A reversible, reaction-based sensor for biol. mobile zinc was designed, prepd., and characterized. The sensing mechanism of this probe is based on the zinc-induced, ring-opening reaction of spirobenzopyran to give a cyanine fluorophore that emits in the de ...
Catalyst design is of major importance for fine chemicals industry due to
complexity of the synthesis and high product quality requirements. Moreover, the
catalyst formulation has to comply with the standards of health, safety and
environmental regulati ...
Cupredoxins perform copper-mediated long-range electron transfer (ET) in biological systems. Their copper-binding sites have evolved to force copper ions into ET-competent systems with decreased reorganization energy, increased reduction potential, and a d ...
With the continued maturation of III-V nanowire research, expectations of material quality should be concomitantly raised. Ideally, III-V nanowires integrated on silicon should be entirely free of extended planar defects such as twins, stacking faults, or ...
