(Multiplicative) Hom-Lie-Yamaguti superalgebras which generalize Hom-Lie supertriple systems (and subsequently ternary multiplicative Hom-Nambu superalgebras) and Hom-Lie superalgebras in the same ...way as Lie-Yamaguti superalgebras Frac generalize Lie supertriple systems and Lie superalgebras are defined. We show that the category of (multiplicative) Hom-Lie-Yamaguti superalgebras is closed under twisting by self-morphisms. Construction of some examples of Hom-Lie-Yamaguti superalgebras is given. The notion of an \(n^{th}-\)derived (binary) Hom-superalgebras is extended to the one of an \(n^{th}-\)derived binary-ternary Hom-superalgebras and it is shown that the category of Hom-Lie-Yamaguti superalgebras is closed under the process of taking \(n^{th}-\) derived Hom-superalgebras.
In this paper, enveloping Lie superalgebras of Bol superalgebras is introduced. The notion of Killing-Ricci forms and invariant forms of these superalgebras is investigated as generalization of the ...one of Bol algebras.

•Highlights on cosmeceutically relevant plant extracts and bioactive compounds.•Usage of proper techniques to extract bioactive compounds from plant is vital.•Traditional and modern ...techniques to extract plant bioactive compounds.
Recently, there has been an increasing demand for bioactive compounds from plants that can be used in the pharmaceutical and nutraceutical industry. This is due to their presumed roles in preventing diseases such as cancer and their ability enhance human skin to make it look younger. Along with conventional methods such as liquid–liquid extraction, solid-phase extraction, and solid-phase micro-extraction, numerous newer techniques have been developed to enhance the extraction of bioactive compounds from their plant sources in a greater scale. These techniques include ultrasound-assisted extraction, pressurized liquid extraction, subcritical water extraction, supercritical fluid extraction, microwave-assisted extraction, and instant controlled pressure drop extraction. This review describes the types of plants that are widely known for their beneficial effects on human skin and the different extraction techniques—along with their basic mechanisms, advantages, and disadvantages—for extracting bioactive compounds from plants.
In this research, the effects of activated carbon from corncob (ACC) biomass as the supporting material were investigated on leakage problem and thermal properties of palmitic acid (PA) as a phase ...change material (PCM) for thermal energy storage, using the impregnation method. The leakage test demonstrated that the addition of ACC significantly reduced the leakage of PA. Furthermore, it was evident from ATR-FTIR spectra and XRD results that PA and ACC did not undergo any chemical reactions, and the crystal structure of PA was not changed, while the ACC was amorphous. According to the SEM result, ACC had a porous structure, and its increase in PA caused a larger pore volume and a higher specific surface area, which could prevent the leakage of PA. The thermal stability of the composites was measured by TGA. The results revealed that the addition of ACC slightly accelerated the pyrolysis of PA, improved the thermal conductivity of PA, and had enough thermal stability below 150 °C to be suitable for building and solar thermal energy storage applications. DSC analysis of the form-stable PCM showed a melting temperature of 61.25 °C and a melting latent heat of 81.57 J g
−1
, and demonstrated high thermal reliability after 10 cycles, indicating excellent energy storage capacity. The BET test revealed that the ACC with 1364.70 m2 g
−1
have a great potential to use for supporting material, and the composites were mesoporous, which prevented the leakage of PA.
The high surface area, lightweight and excellent biocompatibility of nanocellulose (NC) have resulted in its wide application as a bio-based reinforcement agent. In this study, raw oil palm fronds ...leaves (OPFL) were used as the cellulose source to prepare NC. Successive treatments of raw OPFL with bleach, alkali and acid yielded NC in a form of white powder. X-ray diffraction, transmission and field emission scanning electron micrographs showed that the isolated NC formed crystalline needlelike structures with diameters ranging between 10 and 30 nm. The crystallinity index of NC was 45.5%, greater than raw OPFL (25.3%) and cellulose (30.5%). The AFM micrographs showed that the NC exhibited a root-mean-square roughness of 9.146 nm. FTIR-ATR spectra revealed the disappearance of a C=O peak at 1732 cm
−1
with the absence of impurities, while the EDX spectrum further affirmed that lignin and hemicellulose were successfully eliminated. BET surface area of NC (5.108 m
2
/g) was found higher than cellulose (1.4526 m
2
/g). The TGA data revealed that NC decomposed between 120 and 450 °C, with an 80% mass loss that corresponded to sulfate groups (O–SO
3
). In short, the nanometer dimensions of NC extracted from raw OPFL implied its promising applications as a reinforcing agent for improving mechanical properties of nanocomposites.
