<p class="Abstract">This paper illustrates a case study related to the characterisation of corrosion products present on recently excavated artefacts. The archaeological findings, from the Rakafot 54 site (Beer-Sheva, Israel), consist of 23 coins and a pendant, all dating back to the Roman period. Raman spectroscopy was used to identify the corrosion products that compose the patina covering the objects. To facilitate and support their identification, spectra were then processed using principal components analysis. This chemometric technique allowed the identification of two main compounds, classified as atacamite and clinoatacamite, which formed the main components of the patinas. The results of this investigation can help in assessing the conservation state of artefacts and defining the correct restoration strategy.</p>

The current digital era is full of digital devices and to ensure the safety of their data, users utilize the protective armor of passwords using the fingerprints lock, face lock, pin codes and password locks. The trial-and-error method possesses an infinite possibility of passwords in patterns/ pin locks for unlocking the devices. The levels of security ensure that only a limited number of trials are possible before any device blocks itself or makes unlocking harder. In these circumstances, especially when a victim is a deceased person (e. g. an abetment in suicide case), the password is practically impossible to attain through the authorities. However, the data can be retrieved with the unique and distinctive method of Chip-off analysis. In this study, a password protected mobile phone was retrieved from a deceased individual and only the analysis of his/her mobile could lead to investigative insights for catching the perpetrator. The Chip-off method has several difficulties and a password/ pin protected device increases the difficulties for analysis several folds. This study highlights the significance of chip-off analysis in achieving accurate importing and extraction of maximum data along with the use of the hardware/software, MSAB, XRY and other software.

This paper presents advantages and disadvantages of Raman spectroscopy when used for testing banknotes, i.e. in case study I, 1 and 5 dinars banknotes from a private collection dating from 1876 of numismatic value were analyzed, and in case study II, 1000 dinars banknote from circulation together with its counterfeit. In both cases banknotes were analyzed by using Raman spectrometer DXR Raman microscope at the Faculty of Physical Chemistry, with a laser of wave-length 780 nm at 12 mW of power. Specters were recorded under microscope using 50X lens in a range 1800-60 cm-1. Analyses from case study I on both specimens showed spectrum characteristic for fluorescence appearance, therefore intensive signal of fluorescence covered Raman signal. In case study II, it was established that Raman spectroscopy can reliably detect a counterfeit banknote. Research, comparisons and analyses regarding original and counterfeit 1000 dinars note were performed on red banknote surfaces.
