W Hillier et al.
Biochemistry, 36(1), 76-85 (1997-01-07)
The behavior of photosystem II (PSII) reactions was investigated under conditions of decreasing water content by the addition of increasing concentrations of ethylene glycol (EG). The photosynthetic activities were measured for PSII samples either directly in aqueous solutions of EG
G Samanta et al.
Analytical chemistry, 73(9), 2034-2040 (2001-05-17)
An automated continuous instrument for the collection and measurement of aerosol Cr(VI) is described. The system alternately collects the sample on one of two glass fiber filters. After 15-min sample collection on one filter, the sampling switches over to the

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 59(11), 2667-2675 (2003-09-10)
In order to find out about the chemical behaviour of the diphenylcarbazide (DPCI) in water, kinetic and thermodynamic studies were carried out using UV-Vis spectrophotometry within the 0-12 pH range. The kinetic parameters and acidity constant were then determined, and

Biochemistry, 37(39), 13559-13566 (1998-09-30)
Our previous work using the "diphenylcarbazide (DPC)-inhibition assay" has identified four amino acid (two carboxyls and two histidyls) ligands to four Mn2+ bound with high affinity on Tris-washed photosystem II (PSII) membrane fragments [Preston and Seibert (1991) Biochemistry 30, 9615-9624

Talanta, 89, 455-461 (2012-01-31)
A novel sorbent for simultaneous separation of cadmium and copper was prepared by functionalizing SBA-15 nanoporous silica with diphenylcarbazide. A solid-phase extraction method using the above sorbent has been developed to separate and concentrate trace amount of cadmium and copper
