Mechanism of silver nanoparticle toxicity is dependent on dissolved silver and surface coating in Caenorhabditis elegans.
It is found that a lower ionic strength medium resulted in greater toxicity (measured as growth inhibition) of all tested Ag NPs to Caenorhabditis elegans and that both dissolved silver and coating influenced Ag NP toxicity. Expand
More than the ions: the effects of silver nanoparticles on Lolium multiflorum.
This study suggests that growth inhibition and cell damage can be directly attributed either to the nanoparticles themselves or to the ability of AgNPs to deliver dissolved Ag to critical biotic receptors. Expand
Deposition of silver nanoparticles in geochemically heterogeneous porous media: predicting affinity from surface composition analysis.
There was a linear correlation between the average nanoparticle affinity for media composed of mixtures of FeO-GB and GB collectors and the relative composition of those media as quantified by the attachment efficiency over a range of mixing mass ratios of the two types of collectors. Expand
Uptake of silver nanoparticles and toxicity to early life stages of Japanese medaka (Oryzias latipes): effect of coating materials.
Results suggest that while ingestion was common, gills were the principal sites of AgNP uptake, and which interact with skin surface and were taken up via the gills, AgNPs is a source of toxic Ag ions, while itself contribute partially to its toxicity to fish. Expand
Degradation, metabolism, and bound-residue formation and release of Tetrabromobisphenol A in soil during sequential anoxic-oxic incubation.
The results provide the first evidence for release of bound residues during alteration of the redox environment and indicate that sequential anoxic-oxic incubation approaches-considered effective in remediation of environments containing halogenated xenobiotics-do not completely remove Xenobiotics from environmental matrices.

A comparison of five extraction methods for extracellular polymeric substances (EPS) from biofilm by using three-dimensional excitation-emission matrix (3DEEM) fluorescence spectroscopy
Two physical methods (centrifugation and ultrasonication) and 3 chemical methods (extraction with EDTA, extraction with formaldehyde, and extraction with formaldehyde plus NaOH) for extraction of EPSExpand
Gadolinium(III)-Chelated Silica Nanospheres Integrating Chemotherapy and Photothermal Therapy for Cancer Treatment and Magnetic Resonance Imaging.
MRI results show that the Gd@SiO2-PDC nanoparticles are safe T1-type MRI contrast agents for imaging and can thus act as a promising theranostic platform for multimodal cancer treatment. Expand
Unusual Compression Behavior of Nanocrystalline CeO2
There is progressive broadening and intensity reduction of the reflections with increasing pressure, and a dual structure model (hard amorphous shell and relatively soft crystalline core) has been proposed. Expand
High-performance oxygen reduction electrocatalysts based on cheap carbon black, nitrogen, and trace iron.
The real optimal electrocatalyst shows superior high activity for ORR and possesses the best price/performance ratio ever. Expand
New vernocuminosides from the stem barks of Vernonia cumingiana Benth
Seven new stigmastane-type steroidal glycosides, vernocuminosides A-G (1-7), have been isolated from the stem barks of Vernonia cumingiana Benth by spectroscopic and chemical methods, especially the employment of Snatzke's method expressed by the induced circular dichroism spectra. Expand
