A fingerprint thin film

Some observations on fingerprint deposits

“…The major aim of this work is to obtain a better understanding of fingerprints and how they differ from their surroundings. Results on the electrical properties of fingerprints have been reported elsewhere Blott 1973, Thomas 1975) and progress in this field has been recently reviewed (Thomas 1973).…”

Microscopic examination of fingermark residues: Opportunities for fundamental studies

“…Physical information such as morphology of the fingermark ridges, distribution and accessibility of the components within the residue, as well as interactions with the substrate and with the environment are important considerations. This knowledge remains restricted to only a handful of studies conducted nearly four decades ago [20][21][22][23] and should therefore be investigated more thoroughly.…”

A study on vacuum evaporated stearic acid films for low-loss capacitors

“…In the above method, films were formed as a monolayer on the surface of water; so, these films were not free from inherent water content and the electrodes used in these investigations were also contaminated (Agarwal et aZ 1976a). To avoid these difficulties, deposition by vacuum evaporation of the fatty acids, particularly of stearic acid, has been tried and has succeeded without any decomposition, in spite of its high molecular weight (Baker 1971, Thomas 1974. Very limited work on some of its physical properties have been carried out (Agarwal et aZ1976a, Agarwal and Mitsuhashi 1977, Agarwal 1977, Kasilingam et a Z 1977, 1978 and applied in the field of tribology (Baker 1971), forensic science for fingerprints (Thomas 1974), and high-frequency dielectric properties etc.…”
