Comparative assessment of two portable Raman spectrometers for the characterisation of historical natural dye lakes

Journal of Raman Spectroscopy, Volume 54, Issue 11, Page 1303-1313, November 2023., 2023
This paper explores the use of portable Raman instruments to characterise natural dye lakes in paint mixtures. Two dispersive portable Raman instruments, one using a fibre‐optic probe and a 1064‐nm excitation laser and the other using the subtracted‐shifted excitation (SSE) post‐processing algorithm, have been tested in their feasibility to ...

Exploring the Flora of South Sulawesi, Forest Vegetation, and Karst Areas as Bundle Dyeing on Silk Fabrics

International Journal of Forestry Research, Volume 2022, Issue 1, 2022., 2022
The development of dyeing frm natural substances for silk fabrics has been rapidly growing in recent years. This study aimed to explore the plant species prodsucing unique dyes and patterns on silk fabrics. The flowers and leaves of some plant species found at the research sites were assayed for their color and shape expression on the fabrics.

Biochemical aspects of a serine protease from Caesalpinia echinata Lam. (Brazilwood) seeds: a potential tool to access the mobilization of seed storage proteins. [PDF]

ScientificWorldJournal, 2012
Several proteins have been isolated from seeds of leguminous, but this is the first report that a protease was obtained from seeds of Caesalpinia echinata Lam., a tree belonging to the Fabaceae family. This enzyme was purified to homogeneity by hydrophobic interaction and anion exchange chromatographies and gel filtration.
