Preparation, properties, and colorimetric determination of diacetylmethylcarbinol
Archives of Biochemistry and Biophysics, 1957Abstract Methods for the enzymic and chemical synthesis of substrate amounts of diacetylmethylcarbinol have been outlined. Diacetylmethylcarbinol has been characterized chemically and some of its properties studied. A colorimetric procedure for the quantitative determination of diacetylmethylcarbinol has been described.

Colorimetric Properties of Photochromic Textiles
Applied Mechanics and Materials, 2013Photochromism is a chemical process in which a compound undergoes a reversible change between two states having separate absorption spectra, i.e. different colors. The change of color in one direction occurs under influence of electromagnetic radiation, usually UV light, and in the other direction by altering or removing the light source or ...

Removal of Ink by Defibration: Colorimetric Properties of Recycled Paper
Conference on Colour in Graphics, Imaging, and Vision, 2002The removal of roto ink from the newspaper prints by defibration is such a laboratory process, which does not demand the usage of any chemicals, but the ink is washed away by tap water. From the purified fibers, the new paper is produced. The lightness of such paper will be smaller than the lightness of the original paper.

Label-free colorimetric estimation of proteins using nanoparticles of silver [PDF]
Nano-Micro Letters, 2010 Metallic nanoparticles have received considerable attention in bioassays and diagnostics due to their unique surface plasmon resonance (SPR) properties. Gold nanoparticles have been employed for the development of SPR-based colorimetric bioassays. In the

Color reproduction on inkjet printers and paper colorimetric properties
SPIE Proceedings, 2003The goal of this work is to study the relationship between the colorimetric characteristics that identify a kind of paper and those that allow us to evaluate its color reproduction capabilities on inkjet printers. A set of 29 different commercial papers from several companies has been tested.

Colorimetric study of the electrochromic properties of a conducting polymer
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1990The in-situ reflection spectra of polyaniline, poly-N-methylpyrrole and polythiophene were measured. The chromaticity coordinates were calculated by the CIE (Commission Internationale de l'Eclairage) 1976 (L*, u*, v*) colour space method. In the chromaticity diagram, polyaniline shows two turning points which indicate the existence of a different ...

Colorimetric properties of TiN coating implanted by aluminum
Journal of Alloys and Compounds, 2005Abstract TiN coating was prepared by cathodic arc deposition and implanted aluminum using a metal vacuum vapor arc ion source with doses ranging from 5 × 1016 to 2 × 1017 ions/cm2. The purpose of this work was to determine the dependence of the colorimetric properties of TiN films on the implanting conditions, especially by the aluminum ion ...

Modelization of the optical and colorimetric properties of lustred ceramics
Applied Physics A, 2006The lustre decoration is one of the most famous decorations of glazed ceramics in the Mediterranean basin. Unfortunately, the recipes and fabrication techniques used during medieval times have been lost and that is why these objects have been widely studied. But until now, little was known on their optical properties.

Colorimetric properties of reversible thermochromic printing inks
Dyes and Pigments, 2010The colorimetric properties of three, leuco dye-based thermochromic inks at 31 C activation temperature were studied. The inks had similar pigment particle size distribution and comparably thick microcapsule shells with similar stability against oxygen plasma etching. The colour of the inks was dependent on temperature as well as the thermal history of

The Colorimetric Properties of the Deinked Pulp from Digital Prints
Conference on Colour in Graphics, Imaging, and Vision, 2004Optical properties of handsheet during flotation of prints from digital and conventional offset printing have been observed in this paper. The prints for processing were made on web digital offset printing machine whit six colors and on two models on sheet fed digital offset machines with four colors on different printing substrates.
