“…C-N-C stretching vibration of imide ring is also observed as bands around 1,350 cm -1 and the band CH3 group showed a symmetric stretching around 2866 cm -1 . Further, the C-O-C bond (alkoxy) shows a strong absorption band 44,45 at 1,030 cm -1 . The appearance of new absorption peaks at 2953 cm -1 (C-H stretching) and 1457 cm -1 (C-H bending) also specified the formation of bismaleimide ring 41 .…”

A novel water-soluble and flexible aliphatic bismaleimide resin (BMIDPE) was synthesized by using maleic anhydride and polyether diamine (PEA) and toughened with diglycidyl ether of bisphenol-A (DGEBA) with 4,4'diamino diphenyl methane (DDM) as curing agent. This BMIDPE toughened DGEBA were further altered with various weight percentages (0.5, 1.0 & 1.5 wt %) of multi-walled carbon nanotube (MWCNT) to obtain MWCNT/BMIDPE/DGEBA nanocomposites. The thermal studies indicated that the MWCNT/DGEBA nanocomposites displayed improved thermal stability and decreased the glass transition temperature (Tg) than that of the neat epoxy matrix. The prepared nanocomposites displayed a better dielectric constant than that of the neat epoxy system. From XRD data, it is observed that MWCNT was exfoliated into BMIDPE toughened epoxy. The homogeneous fine dispersion of MWCNTs throughout the DGEBA matrix was ascertained by SEM. The result from mechanical analysis specifies that the inclusion of PEA into the epoxy system increases the toughness. Moreover, it was believed that this new type of BMIDPE toughened DGEBA/MWCNT nanocomposites would be utilized for high-performance applications.

“…They not only maintain the thermomechanical properties but also reduce the rigidness by increasing the film elasticity which, in turn, expanding the application of starch-based plastic films. Some common plasticizers that employed to increase the elasticity of starch-based films include glycerol, sorbitol, polyol, and essential oils [14][15][16][17][18][19] . However, to date, there is no publication concerning the use of taro starch and chitosan plasticized by castor oil.…”

A biodegradable film made of taro starch and chitosan plasticized by castor oil was created through a casting solvent method. This study examined the influence of taro starch and chitosan composition on the thermo-mechanical and morphological properties of the film. We have successfully obtained a film with a smooth surface and compact structure of taro starch. The results showed that the higher proportion of chitosan in the polymer matrix succeeded in increasing the tensile strength and thermal stability of the film. The addition of chitosan into taro starch samples resulted in reducing the water uptake of the film. The film with a balanced ratio of taro and chitosan starch had excellent water resistance, its absorption of water is the lowest of all compositions.

The aim of this research was to assess the nutraceutical potential of Hura crepitans seed oil in food chemi- stry. For that, we determined the phytochemical composition, physicochemical parameters, mineral composition, as well as proximates of the oil under study. The yield of the oil obtained by the Soxhlet method was 47.8 ± 0.2%. According to the phytochemical screening result, the oil contained saponin, alkaloid, terpenoids, steroids, and cardenolides. Quantitative analysis of proximates for the Hura crepitans seed oil displayed 10.1 ± 0.4% of protein, 19.4 ± 0.1% of crude fibres, 14.5 ± 0.5% of carbohydrates, 5.3 ± 0.2% of water, and 2.9 ± 0.1% of ash. Some selected physicochemical parameters such as refractive index, pH, and specific gravity were 1.47; 5.2; and 0.80, respectively. Cloud point was 6.20°C. Metal content determination revealed the presence of mineral substances such as magne- sium (119.51 ± 0.25 mg/kg), potassium (4.25 ± 0.04 ppm), iron (4.01 ± 0.03 mg/kg), manganese (3.66 ± 0.02 ppm), so- dium (2.18 ± 0.02 ppm), calcium (0.11 ± 0.001 ppm), zinc (0.04 ± 0.001 µg/g), and cadmium (0.0028 ± 0.0004 mg/kg). However, such minerals as nickel and lead were not detected. The structural analyse was carried out based on phy- sicochemical properties and spectroscopic data of the Hura crepitans seed oil. The results of the research proved the nutraceutical potential of this oil to use as raw materials in various areas of industry.
