Spiropyran modified micro-fluidic chip channels as photonically controlled self-indicating system for metal ion accumulation and release [PDF]

, 2009
In this paper, we show how through integrating the beneficial characteristics of micro-fluidic devices and spiropyrans dyes, a simple and very innovative chip configured as an on-line photonically controlled self-indicating system for metal ion ...

The influence of natural pulmonary surfactant on the efficacy of siRNA-loaded dextran nanogels [PDF]

, 2013
Aim: Topical administration of siRNA nanocarriers is a promising approach in the treatment of pulmonary disorders. Pulmonary surfactant, covering the entire alveolar surface of mammalian lungs, will be one of the first interfaces that siRNA nanocarriers ...

Leaching Properties of Estuarine Harbor Sediment Before and After Electrodialytic Remediation [PDF]

, 2007
Electrodialytic remediation (EDR) can be used to extract heavy metals from a variety of different media. In this work, contaminated harbor sediments from two locations in the United States and one in Norway were subjected to EDR, and were compared with ...

Proton and cadmium adsorption by the archaeon Thermococcus zilligii: Generalising the contrast between thermophiles and mesophiles as sorbents [PDF]

, 2010
Adsorption by microorganisms can play a significant role in the fate and transport of metals in natural systems. Surface complexation models (SCMs) have been applied extensively to describe metal adsorption by mesophilic bacteria, and several recent ...

Complex networks on hyperbolic surfaces [PDF]

Physica A: Statistical Mechanics and its Applications, 2005
We explore a novel method to generate and characterize complex networks by means of their embedding on hyperbolic surfaces. Evolution through local elementary moves allows the exploration of the ensemble of networks which share common embeddings and consequently share similar hierarchical properties.

Electrochemical modification of platinum and glassy carbon surfaces with pyridine layers and their use as complexing agents for copper (II) ions

Open Chemistry, 2019
The electrochemical grafting of the “in-situ” prepared diazopyridinium salt have permitted the attachment of pyridine moieties onto platinum and glassy carbon surfaces. The modification of the electrode surfaces is observed by a redox probe.

Copper Complexation by Dissolved Organic Matter in arid Soils: A Voltametric Study [PDF]

, 2018
A voltammetric method was used to estimate the complexing capacity of water extracts from both desert soils sampled at the root zone of creosote and salt cedar plants, and in soils from interspace or background regions where no vegetative influence was ...

Surface Complexation Modelling of Wettability Alteration during Carbonated Water Flooding

Energies, 2022
CO2 capture and utilization is an effective tool in reducing greenhouse gas emissions and hence, combating global warming. In the present study, surface complexation modeling (SCM) with the geochemistry solver, PHREEQ-C, was utilized to predict the ...
