Blue metal complex pigments involved in blue flower color
The blue pigment of cornflower, protocyanin, has been investigated for a long time, but its precise structure was not entirely explained until recently. The molecular structure of the pigment was recently shown to be a metal complex of six molecules each of anthocyanin and flavone glycoside, with one ferric iron, one magnesium and two calcium ions by X-ray crystallographic analysis. The studies...
متن کاملExfoliation of Egyptian Blue and Han Blue, Two Alkali Earth Copper Silicate-based Pigments
In a visualized example of the ancient past connecting with modern times, we describe the preparation and exfoliation of CaCuSi4O10 and BaCuSi4O10, the colored components of the historic Egyptian blue and Han blue pigments. The bulk forms of these materials are synthesized by both melt flux and solid-state routes, which provide some control over the crystallite size of the product. The melt flu...
متن کاملEnvironment-Friendly Safety
Of special interest in verification are safety properties, which assert that the system always stays within some allowed region. For closed systems, the theoretical properties of safety properties as well as their practical advantages with respect to general properties are well understood. For open (a.k.a. reactive) systems, whose behavior depends on their on-going interaction with the environm...
متن کاملEnvironment-friendly photolithography using poly(N-isopropylacrylamide)-based thermoresponsive photoresists.
We report a novel approach for the temperature-triggered development of water-soluble photoresists based on photocleavable poly(N-isopropylacrylamide) copolymers. These copolymers are soluble in an aqueous environment below their Lower Critical Solution Temperature (LCST). Upon UV irradiation, the photocleavable groups are deprotected resulting in an increased LCST. Thus, the illuminated parts ...
متن کاملEquation-based TCP-friendly congestion control under lossy environment
A major problem in supporting multimedia streaming in the Internet is that the streaming protocol used tends to take bandwidth away from competing TCP traffic streams. Thus it is important to devise rate based protocols that are TCP -friendly. In the paper we examine the effectiveness of two important models in devising TCPfriendly rate based protocols in lossy environment such as wireless netw...
