In Part 1 (preceding paper) a method of demonstrating the presence of leuco-anthocyanins in plant tissues has been described. A modified version of this method, in which paper chromatographic separation of the anthocyanidins is not carried out, has been applied to the leaves of several hundred species of plants. As a confirmatory test, in the great majority of instances the vanillin reaction ha...
The application of toxic triphenylmethane dyes such as crystal violet (CV) in various industrial processes leads to large amounts of dye-contaminated sludges that need to be detoxified. Specific bacteria residing in wastewater treatment plants (WWTPs) are able to degrade triphenylmethane dyes. The objective of this work was to gain insights into the genetic background of bacterial strains capab...
Interactive thermochromic coatings based on Leuco dye are most commonly used in research for building cooling applications. The developed by the authors primarily aimed at industrial applications metal substrates, mainly safety reasons. Thanks to a higher transition temperature associated with significant change shade, they have potential prevent burns and can be as an element of active protect...
was concerned to the white matter, and developing more or less abruptly in apparently normal individuals. Perivascular necroses, perivascular and focal demyelination, haemorrhages, oedema, and cellular infiltration were the chief components of the pathological picture." In the 12 years since Hurst's paper appeared remarkably few similar cases have been reported, and in fact only five further ex...
در این مطالعه نانوالیاف pva/dye در غلظت های مختلف با موفقیت آماده و به عنوان لایه حساس کننده در سلول های خورشیدی استفاده شد. نانوالیاف به دست آمده با روش تحلیلی مانندftir ، طیف سنجی uv-visو sem مورد بررسی قرار گرفت. تجزیه و تحلیل ساختاری وجود رنگزا در نانوالیاف pva/dye الکتروریسی شده را تایید کرد. باتوجه به نتایج جذب uv-vis راندمان تبدیل بالاتر برای نانولایه ی pva/dye که در غلظت 15? از محلول پل...
