- Coloring-decoloring behavior of amphiphilic fluoroalkyl end-capped N-(1,1-dimethyl-3-oxobutyl)acrylamide--acryloylmorpholine cooligomer/fluorescein nanocomposites in protic and aprotic solvents.
- Sawada H, Izumi S, Sasazawa K, Yoshida M.Author information Department of Frontier Materials Chemistry, Graduate School of Science and Technology, Hirosaki University, Hirosaki 036-8561, Japan. hideosaw@cc.hirosaki-u.ac.jpAbstractAmphiphilic fluoroalkyl end-capped N-(1,1-dimethyl-3-oxobutyl)acrylamide-acryloylmorpholine cooligomer/fluorescein nanocomposites afforded brilliant yellow-colored solutions in not only protic solvents such as methanol and ethanol but also protic-like solvents such as dichloromethane and 1,2-dichloroethane, respectively. However, the corresponding non-fluorinated cooligomer/fluorescein composites and parent fluorescein gave the colorless solutions under similar conditions. On the other hand, unexpectedly, such brilliant yellow-colored solutions provided by these fluorinated nanocomposites completely disappeared in aprotic solvents such as N,N-dimethylformamide, dimethyl sulfoxide, and tetrahydrofuran. Thus, these fluorinated fluorescein nanocomposites can exhibit a coloring-decoloring behavior through solvatochromic response.

- Decoloring hemoglobin as a feedstock for second-generation bioplastics.
- Low A, Lay M, Verbeek J, Swan J.Author information School of Engineering, Waikato University, Hamilton, New Zealand. awk1@waikato.ac.nzAbstractThe color of red blood cell concentrate (RBCC) limits its application in human food, but there is potential to use it for second-generation bioplastics. Several methods have been developed to remove color from RBCC, but they are expensive or may produce difficult-to-remove toxic residues. Hydrogen peroxide treatment is a cheaper alternative. The effects of RBCC concentration, pH, and reaction temperature were the most important factors influencing the decolorizing process. They were investigated with the aim of developing a method that could be scaled to commercial level for producing a bioplastic feedstock. Initial trials showed pH was an important factor for decolorization and foaming. At pH 15 there was a 96% reduction in solution color and 8.4% solids were lost due to foaming. There was a 76% reduction in solution color at pH 2 and only 2.6% solids were lost due to foaming. The optimal reaction conditions were to centrifuge 9% w/w, pH 2 aqueous RBCC solution to remove aggregates. The solution was reacted at 30°C with 7.5 g of 30% (w/w) hydrogen peroxide. These conditions achieved a 93% reduction in solution color after 3 hr and the molecular weight of the decolored protein was not significantly reduced.

- 通常,RGB 成分からなるカラー画像をモノクロ画像に変換するには,各画素の明度成分をモノクロ画像の画素値とする.この変換は不可逆であり,この変換によって得られたモノクロ画像から原画像の色情報を復元することは不可能である.近年,カラー画像の色情報をモノクロ画像内に埋め込んでおくことで,カラー画像復元可能なモノクロ変換に関する研究が行われている.しかし,従来手法はアルゴリズムの性質上,色数に制限があり …
