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.

On the Apparent Solubility of Leuco Compounds of Sulfur Dyes
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 ...

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors
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.

A scalable, color‐adaptive radiative cooling coating is developed to enable dynamic spectral regulation via a reversible thermochromic transition at ~45 °C and a high solar reflectance of 91.7%. The coating achieves 4.44 °C outdoor sub‐ambient cooling while providing robust superhydrophobicity and environmental durability through its micro/nano ...

Human platelet‐derived extracellular vesicles (EVs) colocalize with cellular organelles, early endosomes and lysosomes, in neurons differentiated from human induced pluripotent stem cells, both in naïve and hypoxic conditions. Furthermore, the functional activity of neurons is changed by hypoxia and by pre‐ and post‐treatment with the EVs in hypoxic ...

Plasma Membrane‐Promoted Aggregation of BODIPY Dimers Enables Live‐Cell Super‐Resolution Imaging
BODIPY dimers are introduced as membrane probes exhibiting dynamic, environment‐dependent intermolecular interactions within lipid bilayers. Transient aggregation between molecules drives switching between open, H‐aggregated, and J‐aggregated states, enabling efficient blinking. This behavior allows dual‐color imaging, with green emission outlining the

Analysis of the Degradation of Thermochromic Sensors in Electrical Devices
This study examines the degradation of microencapsulated leuco thermochromic pigments, both pure and embedded in epoxy, under thermal, cyclic, and QUV aging. UV radiation is the main factor causing irreversible loss of thermochromism due to microcapsule damage and solvent loss, while thermal exposure produces minor effects.

Color Development and Tribo-charging Characteristics of Leuco Dyes
The color development and tribo-charging characteristics of the leuco dyes were investigated. Seven types of leuco dyes were dissolved into a styrene-acryl copolymer solution to prepare a dye-solution. When a prescribed amount of the t-butyl salicylate-Zn complex (SZC) was added to the dye-solution the solution developed color. The maximum absorbance A
