“…The Sengon wood sawdust has a higher CI (52.8%) than the others, confirming their chemical composition with high alpha cellulose content. The density of wood sawdust of Sengon (0.4-0.75gr/cm 3 ) and Pine wood (0.77-0.86gr/cm 3 ) is lower than Teak wood (0.60-1.16gr/cm 3 ) [27].…”

This research compares the physical and thermal characteristics of three kinds of wood sawdust applied to bio-composites filler. Wood Sawdust of Sengon (softwood), Pine (softwood), and Teak (hardwood) have a crystalline structure (cellulose). The hydrochloric acid test found cellulose and other lignocellulosic content, such as hemicellulose and lignin. It contributed to the plant's strength. Adding a good filler in the polymer as a matrix with a high cellulose composition can increase the inter-mechanical bonding of bio-composites. Sengon sawdust has 48.98% cellulose content and contributes to the highest crystallinity index of 52.8%, calculated by the X-ray diffraction test. A high aspect ratio (L/D) on the bio-composite positively impacted the mechanical strength of bio-composite materials. The Scanning Electron Microscope (SEM) can show the morphology and calculate the aspect ratio of wood sawdust. Aspect ratio of wood sawdust from high to low i.e. Sengon (5.8), Pine (3.9), and Teak (1.5), respectively. Fourier transform infrared (FTIR) test to detect the twelve absorbance frequencies of the cellulose, hemicellulose, and lignin. Thermal degradation of all wood sawdust has the same initial degradation temperature (Tonset) by 255℃ and maximum degradation temperature (Tmax2) by 300℃.

“…Bangkirai is regarded as high-quality wood because of its excellent biological endurance features [26]. Due to the comparatively high specific gravity of Bangkirai wood, fungi have a more difficult time surviving on it [27].…”

Wood, as a renewable material, can be used for indoor and outdoor products. Meranti and Bangkirai as commercial woods, are used outdoors. The wood used outdoors will experience wood cell damage and discoloration on the surface. The research aims to determine the pattern of damage and discoloration of wood vessel cells in Meranti and Bangkirai wood due to weather exposure for 5 months in Samarinda. The wood cell damage was observed microscopically, and changes in wood vessel cells colour were observed using the CIE lab method on parameters L*, a*, b*, and ΔE. The study’s results showed that after being exposed to the weather for 2 months, the vessel cells of Meranti and Bangkirai wood began to experience degradation. In Meranti wood, the vessel cells were completely degraded and left cracks after 4 months, while in Bangkirai wood, it was 5 months. After being exposed to the weather for 5 months, Meranti wood vessel cells experienced changes in the parameters ΔL -10.65, Δa -14.68, Δb -12.89, and ΔE 22.25. While Bangkirai, ΔL -7.01, Δa -12.84, Δb 15.95 and ΔE 21.64.

“…Since the components of the quinone/hydroquinone redox couple are easily inter-convertible and closely balanced energetically [ 1 , 2 ], they serve as important links in electron transport processes during metabolic pathways and many biological reactions [ 3 ], also explaining their use in industrial applications [ 4 , 5 , 6 , 7 ]. Among naturally occurring quinones, lawsone (2-hydroxy-1,4-naphthoquinone), a red-orange pigment, present in henna, has long been used for the coloration of the skin, hair, and textile materials [ 8 ].…”

A prospective study of the dye properties of non-toxic lawsone thiophenyl derivatives, obtained using a green synthetic methodology allowed for the description of their bathochromic shifts in comparison to those of lawsone, a well-known natural pigment used as a colorant that recently also has aroused interest in dye-sensitized solar cells (DSSC). These compounds exhibited colors close to red, with absorption bands in visible and UV wavelength range. The colorimetric study showed that these compounds exhibited a darker color than that of lawsone within a range of colors depending on the substituent in the phenyl ring. Computational calculations employing Density Functional Theory (DFT) and Time-Dependent Density Functional Theory (TD-DFT), showed that the derivatives have lower excitation energies than lawsone, while the alignment of their frontier orbitals regarding the conduction bands of TiO2 and ZnO and the redox potential of the electrolyte I−/I3− suggests that they could be employed as sensitizers. The study of the interactions of the lawsone and a derivative with a TiO2 surface model by different anchoring modes, showed that the adsorption is thermodynamically favored. Natural bond orbital (NBO) analysis indicates a two-center bonding (BD) O-Ti as the main interaction of the dyes with TiO2.
