Thai local clays: Munpoo clay (MC) and Dindang clay (DC) were utilized as the adsorbents for preparation of the lake pigments from sappan wood. The lake pigment which was prepared by using MC as the adsorbent (L-MC) appeared reddish-brown while a deeper reddish-brown color of the lake pigment (L-DC) was obtained by using DC as the adsorbent. Characterization of MC, DC, L-MC, and L-DC was accomplished by XRD, SEM, FT-IR, BET, TGA and UV-Vis DRS. The effects of adsorbent dosage, pH of sappan wood extract and time on the adsorption were also investigated. The results revealed that silicon oxide and aluminium silicate hydroxide were identified as the main component of MC and DC. L-MC and L-DC exhibited similar XRD pattern compared to MC and DC but with the lower crystallinities. Brazilein from sappan wood could not only form complexes with Al and Si on the surface of the clays but also interact with clay surface via electrostatic interactions, which led to the reddish-brown color of L-MC and L-DC. Furthermore, our method could benefit and promote uses of natural clays in the production of lake pigment which could be used in paints and textile dyeing processes.

“…The 9-AA core structure also presents many applications in different areas. For instance, it can be used as specific marker [34], against neurodegenerative diseases and protozoa [35] and anticancer [36,37]. Many of these applications are directly related to the aromatic rings conjugation present in the 9-AA and its derivatives, resulting in a variety of energy absorption features in the electromagnetic spectrum.…”

Matrix-assisted laser desorption/ionization (MALDI) has evolved to become a well- established technique during the last decades. Because of matrix peak interference in the low molecular-weight region, however, new matrices are often studied with the purpose of improving the spectral quality under m/z 500. Herein, we present the substance 2,4,5,7-tetranitro-9-aminoacridine (TNA) as a suitable alternative matrix for lipid detection in the positive-ion mode. TNA is obtained from 9-aminoacridine, a matrix commonly used to analyze lipids in negative-ion mode, with the addition of 4 nitro groups through a synthetic path. The procedure results in a highly conjugated system that presents a bigger electronic dispersion and therefore higher UV absorption. First, we demonstrated the high sensitivity of TNA for retinol. Second, TNA was applied to detect lipids in the liver of the water rat Nectomys squamipes. By using this natural model of hepatic steatosis (fat liver), a condition in which there is excessive accumulation of lipids, TNA provided a clearer identification of three species of polyunsaturated fatty acids (PUFAs) compared to other matrices. TNA presents better sensitivity and spectral resolution, little or no interference from matrix ions, high intensity of signal and low cost with high yield of matrix production.
