The document in question was a reproduction of a 1923 document. The reproduction was allegedly made in 1946, but it was suspected to have been made at a later date by a photocopying method. A chemical analysis showed that the reproduction was not mad

This work treats writing inks, particularly ballpoint pen inks. It reviews those ink aging methods that are based on the analysis (measurement) of ink solvents (e.g., 2-phenoxyethanol, which is the most common among ballpoint pen inks). Each method i

A recent article by San Roman et al. (2015) treats the problem of determining the age of ink writing using the MHS-SPME technique. Ballpoint pen inks are studied since they tend to age more slowly than other writing inks (i.e., they contain solvents

When writing ink is placed on a substrate, a drying process begins. This process is dependent on the composition of the ink and of the substrate. Lociciro et al. provide an equation that describes the drying process based on models developed by earli

Developing and implementing a generally accepted procedure for the dating of ink found on documents using dynamic approaches has been a very formidable undertaking by forensic document examiners. 2-Phenoxyethanol (PE), a common volatile organic compo

The evaporation of a solution consisting of a non-volatile solute dissolved in a volatile solvent has been previously treated using a simple model called the beaker model. This model considers the solution to be in a non-porous container that has ver

The synthesis of the previously reported thianinhydrin ( 12 ) was achieved from 3-methylthiophene via the corresponding 5,6-dihydrocyclopenta[ b ]thiophen-4,6-dione ( 10 ). Conversion of 10 to the tricarbonyl ( 12 ) proceeded in good yield using dime
