An integrated Raman spectroscopy and self-organizing feature map chemometrics analysis for the discrimination of gel inks by Asri, Muhammad Naeim Mohamad

“…In forensic investigation, it was reported that 80% handwritten documents were written using ballpoint pens. Therefore, due to the lack of objectivity in interpreting gel inks, this study proposed using novel chemometric techniques for discriminating gel-pen inks in forensic investigation. …”

Analysis of the Aging Processes of Writing Ink: Raman Spectroscopy versus Gas Chromatography Aspects by Nikolai M. Grechukha, Kseniya O. Gorshkova, Maxim S. Panov, Ilya I. Tumkin, Elizaveta O. Kirillova, Vladimir V. Lukianov, Natalia P. Kirillova, Vladimir A. Kochemirovsky

“…This work is devoted to the extremely popular but poorly developed scientific and forensic problem of the estimation of the actual dates of inscriptions placed on paper and made by ballpoint pens. It is shown that the degradation of writing inks with time may be controlled via Raman spectroscopy and gas chromatography. …”

Identification of fountain pen ink properties which determine the amount put on paper during handwriting by Ines FRITZ

“…The differences to ballpoint pens, rollerballs or pencils are in the tactual perception of the nib gliding over the paper surface and in the visual impression of a freshly drawn ink line with all the colour impressions and changing light reflections when a wet line dries and reveals either shading or sheen. …”

Rethinking the Ethics of Prisoner Organ Donation by Katrina Hui

“…In 1996, two Shanghai men were executed for the theft of badminton rackets and ballpoint pens.15 Inconsistencies in punishment are common; government officials found guilty of embezzling millions have received suspended death sentences, ultimately allowing them to live.8 These cases highlight concerns that criminal punishment in China is liable to corruption and that many citizens are subject to disproportionately harsh punitive measures. …”
