A Novel Merocyanine Derivative for Probing Polarity at Cubosome Interfaces

open access: yesAsian Journal of Organic Chemistry, EarlyView.
This study develops a synthetic route to C10SP, a polarity‐sensitive sensor embedded in phytantriol‐based cubosomes. Strategic steps included tertiary amine‐mediated amidation to covalently attach a hydrophobic tail and controlled nitrogen methylation to form the iminium moiety within the indolenine scaffold.

Evaluating of the disinfection and water quality effects on UV application in the primary stage of water treatment [PDF]

open access: yes, 2007
Background: Irradiation of water by UV has been considered as an attractive alternative for disinfection because its low-impact, pathogen killing capacity shows tremendous promise for meeting today's drinking water regulatory requirements. This study has

Potential Application of a Water‐Soluble Fullerene C60 Decorated with Diethylene Glycol in Treatment of Osteoarthritis

open access: yesAdvanced NanoBiomed Research, EarlyView.
A new ethoxyethanol derivative of iminofullerene, F2, is synthesized and labeled with 99mTc to produce 99mTc‐F2. In vitro, compound F2 inhibits the activation of primary mouse bone marrow‐derived macrophages stimulated with lipopolysaccharide. Moreover, 99mTc‐F2 is selectively enriched in the injured joints of mice. Inflammatory macrophages play a role

Physico-chemical factors and bacteria in fish ponds [PDF]

open access: yes, 2000
Analyses of pond water and mud samples show that nitrifying bacteria (including ammonifying bacteria, nitrite bacteria, nitrobacteria and denitrifying bacteria) are in general closely correlated with various physico-chemical factors, ammonifying bacteria

Low toxic corrosion inhibitors for aluminum in fresh water [PDF]

open access: yes
Combinations of chemical compounds that reportedly reduce the corrosion of aluminum in fresh water were evaluated. These included combinations of borates, nitrates, nitrites, phosphates, silicates, and mercaptobenzothiazole.

Intercomparison of field measurements of nitrous acid (HONO) during the SHARP campaign [PDF]

open access: yes, 2014
Because of the importance of HONO as a radical reservoir, consistent and accurate measurements of its concentration are needed. As part of SHARP (Study of Houston Atmospheric Radical Precursors), time series of HONO were obtained by six different ...

Nitrite metabolism in the cyanobacterium Anabaena cycadeae: Regulation of nitrite uptake and nitrite reductase by ammonia [PDF]

open access: yesFEMS Microbiology Letters, 1992
Nitrogen regulation of nitrite uptake and nitrite reductase was studied in the cyanobacterium Anabaena cycadeae and its glutamine-auxotrophic mutant. The development of the nitrite-uptake system preceded, and was independent of, the development of nitrate reductase.
