On the Apparent Solubility of Leuco Compounds of Sulfur Dyes
The Journal of the Society of Chemical Industry, Japan, 1960 4種類の硫化染料,Blue BB,Indigo R, Dark Brown DおよびOrange OAのリウコ化合物の見掛け溶解度を測定した。その値は還元浴の組成によって変化する。過剰の硫化ナトリウムの量が増すと,はじめのうちは,リウコ化合物の見掛け溶解度は増大するが,非常に多量(2.38N)の硫化ナトリウムを用いた場合には,かえって見掛け溶解度は減少する。また,過剰の硫化ナトリウムの一部を硫酸ナトリウムで置きかえると,硫酸ナトリウムが50%までは見掛け溶解度はやや増大するが,74%にいたると見掛け溶解度は減少し,特に染料使用量の大きい時には著しく減少する。またリウコ化合物の見掛け溶解度は,カセイソーダの添加によりやや減少する。これらの結果は,過飽和状態に溶解 ...

Angewandte Chemie International Edition, EarlyView.This work explores the interactions between the oxazine dye ATTO655 and two macrocyclic hosts using optical (single‑molecule) spectroscopy. Although ATTO655 forms a classical inclusion complex with cucurbit[8]uril (CB8), its interaction with p‑sulfonatocalix[4]arene (sCX4) leads to the formation of dim exclusion complexes.

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors
Biotechnology and Bioengineering, EarlyView.ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.
