A Ligand Exchange Model for the Adsorption of Inorganic and Organic Ligands at Hydrous Oxide Interfaces
Specific adsorption of organic and inorganic weak acids and
of anions on hydrous oxide surfaces and the concomitant influences
upon surface charge can be interpreted as ligand exchange reactions
at the reactive surface sites. Direct (inner sphere) binding of
the ligands to the surface is postulated. The extent of adsorption
and its pH dependence can be explained by considering the affinity
of the surface sites and those of the ligands. Surface equilibrium
constants have been determined experimentally for various surface
reactions; they can be used to predict extent of adsorption and
resulting surface charge. The adsorption of simple weak acids or
their anions is largest around the pH value of pH = pK. The surface
complex formation constants show the same trend in stability
as the corresponding solute complex formation constants; thus
surface coordination equilibrium constants can be estimated from
the corresponding complex formation constants in solution

Test Targets 7.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control
Test Targets is a culmination of teaching and learning that reflects quality and analytic aspects of printing systems and their optimization. The creation of the Test Targets publication is a total experience that reflects the innovation, problem solving, and teamwork of the diverse team of faculty, staff, students, and professionals responsible for its contents and production
Die Neupositionierung des Wealth Management in der Schweiz : Entwicklungen und ihre Auswirkungen auf die Soll-Kompetenzen in der Kundenberatung
StudieDie vorliegende Studie zeichnet ein umfassendes Bild zur Neupositionierung des Wealth Management in der Schweiz. Sie stützt sich dabei namentlich auf eine Online-Befragung von in der Kundenberatung tätigen Personen und auf persönliche
Interviews mit Führungskräften von Schweizer Banken ab. Dabei stand insgesamt die Frage im Zentrum, wie sich die Rahmenbedingungen für die Beratung von Privatkunden im Wealth Management verändern werden und was dies für die zukünftigen
Soll-Kompetenzen von Kundenberatern und den Aus- und Weiterbildungsbedarf bedeutet
Test Targets 8.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control
Publishing is both a journey and a destination. In the case of Test Targets, the act of creating and editing content, paginating and managing digital assets, represents the journey. The hard copy is the result or destination that readers can see and touch. Like the space exploration program, everyone saw the spacecraft that landed on the moon. It was the rocket booster that made the journey from the earth to the moon possible. This article portrays the process of capturing ideas in the form of digital data. It also describes the process of managing digital assets that produces the Test Targets publication
Test Targets 6.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control
Test Targets is a collection of scholarly papers contributed by faculty, students, and alumni of Rochester Institute of Technology. We realize the importance of having faculty set examples as authors for students to follow. We have a three-course sequence over a time span of a year to prepare students to publish their first articles when completing Tone and Color Analysis, Printing Process Control, and Advanced Color Management. In this instance, Test Targets 6.0 is a part of the course content in the Advanced Color Management course
Test Targets 10: A Collaborative effort exploring the use of scientific methods for color imaging and process control
Th ere are six papers that were written, peer reviewed, and published in Test Targets 10. Two papers focus on printing standardization and conformity assessment. Chung describes aims and tolerances specified in ISO 12647-2 and the use of color measurement and data analysis for conformity assessment. Urbain and Khoury describe data reception requirements in ISO 12647-2 and ISO 15930 and the use of a test pdf file to assess conformity of any pdf workflow.
Test Targets 10 will likely be remembered as the publication that covers OBA (optical brightening agents). Two papers focus on OBA. Tian and Chung report the effect of paper containing OBA on printed colors and how such effect can be corrected using different mathematics. Sigg and Millward report the stability of OBA as a function of exposure to light over time. In addition, Gallery of Visual Interest shows side-by-side the visual effect of pictorial and synthetic color images printed on paper with and without OBA.
Printing conformity is result-oriented and does not dictate the press calibration method used. The fifth paper, authored by Wang, compares the compatibility of two press calibration methods, TVI and G7, by means of gradation compensation and press run simulation. Printing conformity requires that correct inks and paper be used. Verifying that correct inks are used is outside the capability of a printer. Th e sixth paper, authored by Zhang, explores an alternative ink drawdown and ink verification method that could be implemented by printers.
Test Forms is a regular feature of Test Targets. We are pleased to showcase pictorial color reference images, Roman 16 Reference Images, courtesy of Bundesverband Druck und Medien e.V. (bvdm), and many possible uses of these images for printing process control and for color management studies. For example, we can compare the appearance of an image printed from the supplied CMYK file with the image from a supplied RGB file that was converted to CMYK by a color management application
Test targets 5.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control
Test Targets is about scholarship that intimately involves faculty and students in the process of writing and publishing. It is a collection if research papers that require collaborative effort over a time span of three academic quarters. Initially, students learned metrology, color management system, and the use of test targets for device optimization and process control. As time goes by, students are encouraged to identify research topics, formulate methodologies, and carry out experiments and data analyses in order to have specific findings. - p.
Test Targets 2.0: A Collaborative effort exploring the use of scientific methods for color imaging and process control
Test Targets 2.0 was a class project in Test Targets for Graphic Art Imaging in the winter quarter of 2001-2 academic year. The objectives were to put together a collection of custom test forms, developed by Professors Robert Chung and Franz Sigg, and to coach students to showcase possible use of these test forms along with associated Microsoft Excel templates for device calibration and process control when implemented in a color managed digital workflow. - p. iv
