Near infrared (NIR) spectroscopy: a potential new means of assessing multi-phase earth-built heritage

The analysis of clays within historic earth buildings is commonly achieved through X-ray diffraction, which is reliant upon extraction. Portable near infrared spectroscopy allows in situ differentiation between clays.

Analysis of cadmium-based pigments with time-resolved photoluminescence

For the first time we report the band edge and trap state luminescence decay kinetics of cadmium pigments. The measured lifetimes suggest that carrier recombination is highly influenced by non-radiative decay paths such as electron trapping. Our findings highlight how luminescence measurements are useful in the conservation science field.

Looking beneath Dalí's paint: non-destructive canvas analysis

A new analytical method was developed to non-destructively determine pH and degree of polymerisation (DP) of cellulose in fibres in 19th–20th century painting canvases, and to identify the fibre type: cotton, linen, hemp, ramie or jute.
