Liquid samples must be introduced into a 10 mm cuvette, which is the reference path length, in order to obtain universal color coordinates. If possible, the spectrum should be recorded with a wavelength resolution of 5 nm as the factors and formulas provided are expressed for this resolution. The blank is measured with distilled water if the sample is liquid or with a blank solid standard if the sample is solid for example, for reflectance analyses commercial standards of CaCO 3 are often used.

Once the transmittance or reflectance spectra of all the samples have been measured, a mathematical treatment is required to obtain the color coordinates.

Mathematical Modeling with Excel by Brian Albright (2009, Paperback)

Using Template-5nm-for-Students Workbook. In the first sheet, called Template 5 nm , the sample spectrum must be introduced so that all formulas can automatically return the color space coordinates. In addition, some information about this color space and the meaning of its parameters are given. As in the previous sheets, the fourth sheet, called RGB , automatically expresses the obtained R , G , and B values in three graphs: the R graph, the G graph, and the B graph Figure 4 , and the values obtained for each parameter are summarized.

Finally, the sheet called Formulas contains a summary of all equations proposed by the CIE and all formulas used in Microsoft Excel. This sheet was included because teachers may want to introduce some equations to their students, or they may want the students to understand that mathematical treatment of the sample spectrum is not as easy as this spreadsheet file makes it. The file Examples. This file includes four spectra: one spectrum of an orange dye, one of a violet dye, one of a blue dye, and another of a green dye.

These spreadsheet files have been used by chemistry and enology students at our university in order to discuss their experimental results in a laboratory report. Specifically, for chemistry students the color space parameters of different pH indicators phenolphthalein, bromothymol blue, and methyl orange were measured at different pH values. Furthermore, enology students determined the color space coordinates of different wine and alcoholic beverage samples.

The newly developed Microsoft Excel workbooks described here, which not only offer more information on the results but also allow a cell to be colored with an almost identical color to the real sample, have allowed students to understand better and improve their discussion of the results in their laboratory reports. In the first report, the workbook was used in order to better understand the effect of different quantities of polivinylpolipyrrolidone PVPP over the color of red wines. In the second report, the workbook was used in order to describe the color of a wood-aged spirit.

Both reports have been translated from Spanish to English for better comprehension. The files described here were also used in a classroom explanation as a visual and interactive aid. In all cases, the results were satisfactory, and students commented that the sheets provided an easy way to understand color space. In Conclusion. The first Excel sheet was developed so that students can understand the most relevant color spaces, as well as to facilitate the work of teachers when offering explanations for this topic. The second Excel sheet was developed so that researchers working in the laboratory can easily obtain the coordinates of the color spaces most commonly applied in the scientific community.

For this reason, this sheet provides less information that the first sheet, although it can be used to introduce several spectra and thus obtain the color parameters of several samples at the same time.

Ecofriendly ultrasonic natural dyeing of cotton fabric with enzyme pretreatments. Desalination , 1—3 , 62 — 69 , DOI: Elsevier B. Ecofriendly ultrasonic textile dyeing with natural dyes such as Acacia catechu and Tectona grandis show better and faster dye uptake after enzyme pretreatment on cotton fabric, and results of dyeing are better than metal mordanted fabric. It is obsd. The role of enzyme pretreatment is primarily for better absorbency, adherence and dyeability of these dyes on cotton fabric, thereby completely replacing metal mordants with enzyme for adherence of natural dyes on cotton.

SEM show surface characteristics at different stages of dyeing. The effect of sonication on the dyeing is compared with conventional heating. The study also shows enhancement in CIELab values. Elsevier Ltd. CIELAB values were predicted based on a neural network developed for cotton fabric dyed with vinyl sulfone reactive dye.

The neural network developed is a multilayer feed-forward network. To achieve the required depth of color, the CIELAB values of the fabric to be dyed were predicted using trained feed-forward neural network. The results obtained from the network gives an av. The trained network brings out the same error for other dyes as well as for input and output parameters selected beyond the range used for training the network.

Selection of an optimum pH-indicator for developing lactic acid bacteria-based time-temperature integrators TTI. Food Eng. Among all time-temp. For the development of lactic acid bacteria-based TTIs, optimum pH-indicators were chosen as follows. Five kinds of potential pH-indicators and four species of lactic acid bacteria were used to create microbial-based TTIs. The qualifying stds. In particular, the reaction of TTI color development could be enhanced from non zero-order to zero-order. Overall, the optimum pH-indicator for the microbial TTIs was bromocresol green, followed by bromocresol purple, bromophenol blue, chlorophenol red, and congo red, in descending rank order.

In conclusion, the choice of pH-indicators was found to be selective to assure effective color development of TTI. Influence of some pre and postfermentative factors. Food Res.
