Ion doping of graphene for high-efficiency heterojunction solar cells.

Xinming Li et al.

Nanoscale, 5(5), 1945-1948 (2013-01-30)

We demonstrated the p-type chemical doping by chlorine and nitrate anions to enhance the Schottky junction in the solar cell. Nitrate ions were found to be more effective for reducing the sheet resistance and enlarging the work function of graphene

Membrane assisted solvent extraction coupled with liquid chromatography tandem mass spectrometry applied to the analysis of alkylphenols in water samples.

N Salgueiro-González et al.

Journal of chromatography. A, 1281, 46-53 (2013-02-12)

This work describes the development and validation of a novel, simple, sensitive and environmental friendly analytical method for the determination of alkylphenols in different types of water samples. The methodology was based on a membrane assisted solvent extraction of only

Influence of pH changes on chlorine-containing endodontic irrigating solutions.

G Rossi-Fedele et al.

International endodontic journal, 44(9), 792-799 (2011-06-11)

Chlorine-containing solutions are used for broad disinfection purposes. Water disinfection literature suggests that their disinfectant action depends on pH values as this will influence the available free chlorine forms. Hypochlorous acid (HOCl) has been suggested to have an antimicrobial effect

Chlorine gas exposure increases susceptibility to invasive lung fungal infection.

Melissa A Gessner et al.

American journal of physiology. Lung cellular and molecular physiology, 304(11), L765-L773 (2013-04-09)

Chlorine (Cl₂) is a highly irritating and reactive gas with potential occupational and environmental hazards. Acute exposure to Cl₂ induces severe epithelial damage, airway hyperreactivity, impaired alveolar fluid clearance, and pulmonary edema in the presence of heightened inflammation and significant

Reactions of chlorine with inorganic and organic compounds during water treatment-Kinetics and mechanisms: a critical review.

Marie Deborde et al.

Water research, 42(1-2), 13-51 (2007-10-05)

Numerous inorganic and organic micropollutants can undergo reactions with chlorine. However, for certain compounds, the expected chlorine reactivity is low and only small modifications in the parent compound's structure are expected under typical water treatment conditions. To better understand/predict chlorine
