Colorimetry, 2 edition (4) contains all the definitions of colorimetric terms, discusses CIE colorimetric practice and provides many useful tables to perform colorimetric calculations. CIE Technical Committee TC 1-48 deals at the present moment with updating this publication. The update will not change anything basic in CIE colorimetry. It will mainly get the recommendations in line with the re...

A novel thiazolothiazole-based Cu(2+) colorimetric and fluorescent sensor is reported. A highly selective colorimetric change from yellow to dark green was observed among various metal ions after adding Cu(2+). Unique radical formation can engender these highly selective colorimetric and fluorescent changes.

This paper described a convenient semiquantitative method for colorimetric detection of protein with self-calibration integrated on the test strip. Hydrophilic paper was employed as microfluidic device for running colorimetric assay, tree-shaped design was developed to ensure uniform microfluidic flow for multiple branches. The approach was validated with bovine serum albumin (BSA) colorimetric...

As they have been designed to undergo colorimetric changes that are dependent on the polarity of solvents, the majority of conventional solvatochromic molecule based sensor systems inevitably display broad overlaps in their absorption and emission bands. As a result, colorimetric differentiation of solvents of similar polarity has been extremely difficult. Here we present a tailor-made colorime...

some children of borazjan area have minute white flecks, yellow or brown spot areas scattered irregularly over the tooth surface, the causative factor was attributed to excess of fluoride in water. to verify this matter short chemical examination of water samples from endemic area was carried out. the results of water analysis by colorimetric method, using zirconium a1izarin reagent after disti...

Abstract: The colorimetric organization of RGB color images is analyzed through the computation of algorithms which can characterize fractal organizations in the support and population of their three-dimensional color histogram. These algorithms have shown that complex organizations across scales exist in the colorimetric domain for natural images with often non-integer fractal dimension over a...

To characterize color values measured by color devices (e.g. scanners, color copiers and color cameras) in a device{independent fashion these values must be transformed to colorimetric tristimulus values. Often it is assumed that RGBs are approximately linearly related to XYZs and so this transformation is determined by least{squares (LS) linear regression. While the LS method is guaranteed to ...

We report a simple and efficient colorimetric method to screen large numbers of bacterial strains for UV- and X-radiation sensitivity. We used reference radiation-sensitive and control strains of Escherichia coli K-12 to compare our colorimetric method to a standard clonogenic plating method. Our colorimetric method was as accurate as the standard method and was superior in terms of savings in ...
