The Effect of Pollutant Gases on Surfactant Migration in Acrylic Emulsion Films: A Comparative Study and Preliminary Evaluation of Surface Cleaning.

From their first employment in the 1950s, acrylic emulsions have remained widely used as art material today. Although under certain deteriorating conditions they are very stable, if exposed to high humidity and atmospheric pollutant gases, their structural and chemical conformation is strongly affected. Dealing with the resulting surfactant migration, various cleaning treatments were considered over the years.

High resolution nanoscale chemical analysis of bitumen surface microstructures.

Surface microstructures of bitumen are key sites in atmospheric photo-oxidation leading to changes in the mechanical properties and finally resulting in cracking and rutting of the material. Investigations at the nanoscale remain challenging. Conventional combination of optical microscopy and spectroscopy cannot resolve the submicrostructures due to the Abbe restriction.

Developing a Web-Based Smoking Cessation Program and Evaluating Its Effectiveness.

This study, which is based on the Stages of Change Model, aimed to develop a Web-based smoking cessation program and to evaluate its effectiveness. An interventional study with 1 group was conducted with college students from Afyon Kocatepe University. First, the Web-Based Smoking Cessation Program was set up (www.

The effect of transtheoretical model-based individual counseling, training, and a 6-month follow-up on smoking cessation in adult women: a randomized controlled trial.

Background/aim: This study was conducted to determine the effect of transtheoretical model (TTM)-based individual counseling, training, and a 6-month follow-up on smoking cessation in adult women.

Materials And Methods: We carried out this randomized controlled trial in Konya, Turkey. Female subjects were randomly assigned into groups in a 1:1 ratio using block randomization, block size 3 × 3, divided by stages (precontemplation, contemplation, and preparation) and age (20-29, 30-39, and 40-49 years).

A heterobimetallic copper-titanium oxo cluster with a new structural motif.

Abstract: Mixed-metal oxo clusters CuTiO(OOCR) (OOCR = methacrylate, propionate) were obtained by reaction of titanium alkoxides and copper carboxylates with propionic or methacrylic acid.

Mixed-Metal Oxo Clusters Structurally Derived from TiO(OR)(OOCR').

The mixed-metal oxo clusters FeTiO(OPr)(OMc) (OMc = methacrylate), ZnTiO(OPr)(OMc), CdTiO(OAc)(OMc)(HOPr), [CaTiO(OAc)(OMc)] , and [SrTiO(OMc)(HOMc)] were obtained from the reaction of titanium alkoxides with the corresponding metal acetates and methacrylic acid. Their structures are derived from Ti clusters with the composition TiO(OR)(OOCR'). The Ca and Sr derivatives consist of chains of condensed clusters.

Conversion of methacrylate into 2-hydroxy-2-methylpropionate ligands in the coordination sphere of a Ag-Zr oxo cluster.

Reaction of Zr(O(n)Bu)4 and silver acetate with methacrylic acid afforded a mixed-metal cluster with a Ag2Zr8O6 core and both methacrylate and 2-hydroxy-2-methylpropionate ligands.
