Four percent Lumicyano → BY40 in place of solvent black 3 and iron-oxide powder suspensions was also suggested to develop greasy fingermarks on semiporous surfaces.
The PC/ABS substrata were coated with a black, two-component, solvent borne urethane coating (Product 318LE/303LE, Red Spot Paint, Evansville, IN, USA) designed for interior automotive trim.
"We applied solvent on black fingers and saw a white hand.
Fig. 6 FTIR/ATR spectrum of the binding media of the original black layer obtained after solvent extraction.
On the average, the PM from flares is comprised of about 90% elemental carbon (black carbon) and 10% solvent extractable materials.
Figure 2 STM-LE spectra of PTCDI-C7 thin film (blue line) and solvent molecules (black line) on HOPG substrate (Vs = +2.2 V, It = 20 nA, acquisition time = 15 min).
The frozen specimens were embedded in a black gel (carboxymethylcellulose sodium solvent 5 % Brunschwig Chemie, Amsterdam, The Netherlands– mixed with Indian ink 5 % Royal Talens, Apeldoorn, The Netherlands), and placed at −20 °C.
(B ) CD spectroscopy of substrate TM peptides in detergent micelles (red traces) revealed them to be strongly reduced in helicity compared to non-substrates (blue traces); in comparison, non-substrates formed helices in detergent micelles similar in stability to those in the helix-inducing solvent TFE (black dashed traces).
The spectrum shown in black represents the result of a 1-tetradecene (solvent) thin film without PTCDI-C7 molecules on the HOPG substrate.
Prepared by a new single solvent evaporation method (black square), prepared by a classical method (black circle).
After evaporation of the solvents a black condensate is formed, containing about 10 15 % of C60 and C70 fullerenes, as well as small amounts of higher fullerenes.
