The use of tristimulus colorimetry for the determination of hydrogen cyanide in air by a modified König method [PDF]
Journal of the Serbian Chemical Society, 2010 A simple visual and tristimulus colorimetric method (three-dimensional system CIE-L*a*b*) for the determination of trace amounts of hydrogen cyanide in air has been developed.

Towards quantitative SERS detection of hydrogen cyanide at ppb level for human breath analysis
Sensing and Bio-Sensing Research, 2015 Lung infections with Pseudomonas aeruginosa (PA) is the most common cause of morbidity and mortality in cystic fibrosis (CF) patients. Due to its ready adaptation to the dehydrated mucosa of CF airways, PA infections tend to become chronic, eventually ...

Acta Universitatis Sapientiae: Alimentaria, 2020 The physico-chemical and sensory qualities of pupuru analogues produced from co-fermented cassava and breadfruit blends were investigated. Cassava and breadfruit were processed separately and cofermented at different proportions to produce pupuru and ...

Advanced Materials, EarlyView.The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

A NOTE ON THE EFFECT OF CARBON DIOXIDE UPON THE INFLAMMABILITY LIMITS OF HYDROGEN CYANIDE [PDF]
, 1949 The inflammability limits of mixtures of carbon dioxide and hydrogen cyanide in air have been investigated. The effect of the addition of carbon dioxide is to bring the upper and lower inflammability limits of hydrogen cyanide together, until they meet ...

Studies on solvent extraction of free hydrogen cyanide from river water
Bulletin of the Chemical Society of Ethiopia, 2007 A method for free and strongly complexed cyanide measurement in river water was developed. Recovery tests from solution with and without river water, using various solvent combinations and background control were investigated to obtain an accurate and ...

μ-Cyanido-κ2C:N-dicyanido-κ2C-bis(N-ethylethylenediamine-κ2N,N′)copper(II)copper(I)
Acta Crystallographica Section E, 2014 In the title complex, [CuICuII(CN)3(C4H12N2)2], the CuI and CuII ions and a bridging cyanide group lie on a twofold rotation axis. The CuII ion is in a slightly-distorted square-pyramidal coordination environment, with the N atoms of the two symmetry ...

Design Principles for Fluid Molecular Ferroelectrics
Advanced Materials, EarlyView.A major challenge for soft condensed matter is predicting whether a fluid molecular material will form ferroelectric phase with nematic or smectic order. Through systematic synthesis, and by analogy to solid molecular ferroelectrics, it is shown that subtle hydrogen–fluorine (H/F) substitution(s) allows for tuneable syn‐parallel pairing motifs ...
