“…With the rise of modern industry, there has been a significant increase in the use of machinery equipment. As a result, lubricants are frequently used to decrease friction and prolong the longevity of equipment. − Currently, approximately 80% of lubricants are derived from fossil energy resources, , owing to which they pose a significant threat to the environment due to high pollution. − At the same time, the gradual depletion of fossil energy sources has also led to the exploration and advancement of alternative chemicals, and biobased lubricants have arisen due to their eco-friendly and sustainable benefits. , …”

The molecular structure of the lubricating oil highly influences the properties of materials, and the construction of long hydrocarbon structures with highly symmetrical branches is quite challenging. In this work, the efficient coupling of modular molecules (furan, furfural, and aliphatic aldehyde) to C 30 −C 36 starfishtype polyfuran-ring compounds (78% mass yield) was successfully synthesized using a one-pot method at atmospheric pressure, while functionalized SH-containing porous solid phosphate (P/PMO-SH) catalysts were designed and used to catalyze multistep C−C chain alkylation reactions with high spatial site resistance. The in situ introduction of −SH functional groups into P/PMO facilitates the high dispersion of phosphoric acid due to the high specific surface area and well-developed pore structure of the support. In situ infrared experiments provided additional evidence for the promotion of reactant molecule adsorption by sulfhydryl functional groups. Contact angle experiments supported the enhancement of lipophilicity of the catalysts due to these functional groups. The biolubricants produced through Pd/Nb 2 O 5 -catalyzed hydrodeoxygenation exhibit high symmetrical branching and demonstrate performance comparable to that of fully synthetic PAO 4 lubricants commercially available, indicating significant potentials for applications.

With the development of artificial intelligence (AI), tailoring methods for enzyme engineering have been widely expanded. Additional protocols based on optimized network models have been used to predict and optimize lipase production as well as properties, namely, catalytic activity, stability, and substrate specificity. Here, different network models and algorithms for the prediction and reforming of lipase, focusing on its modification methods and cases based on AI, are reviewed in terms of both their advantages and disadvantages. Different neural networks coupled with various algorithms are usually applied to predict the maximum yield of lipase by optimizing the external cultivations for lipase production, while one part is used to predict the molecule variations affecting the properties of lipase. However, few studies have directly utilized AI to engineer lipase by affecting the structure of the enzyme, and a set of research gaps needs to be explored. Additionally, future perspectives of AI application in enzymes, including lipase engineering, are deduced to help the redesign of enzymes and the reform of new functional biocatalysts. This review provides a new horizon for developing effective and innovative AI tools for lipase production and engineering and facilitating lipase applications in the food industry and biomass conversion.

“…Additionally, these lubricants exhibit high lubricity and a significantly lower coefficient of friction compared to petroleum-based lubricants. The successful formulation of any lubricant product depends on the multi-purpose optimization of the types and concentrations of raw materials and additives to meet specific application requirements and specifications (de Sousa et al, 2022). When it comes to replacing or reducing the use of petroleum derivatives in industry of lubricant, vegetable oils are the better alternative, consequently the most studied.…”

Polyols are widely synthesized from fossil sources and applied in multiple sectors of the industry as raw material for polyurethane production and also as lubricants. Although the preparation method normally used is efficient and practical, it is necessary to develop environmentally friendly synthesis route that reduce pollution. This study focuses on an alternative synthetic route for the synthesis of polyols using only raw materials from renewable sources. Polyols were successfully obtained by modifying castor oil and epoxidized soybean oil through transesterification, transamidation and oxirane ring opening. The polyols were then characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (1H and 13C‐NMR), acidity index (AI), thermogravimetry (TGA), differential scanning calorimetry (DSC), size exclusion chromatography (SEC), dynamic viscosity and exploratory scanning of ecotoxicological parameters using Artemia salina. The results highlight the promising potential of transamidated castor oil (TACO) polyol in the field of biolubricants, attributed to its high viscosity index, oxidative stability and, ecofriendly behavior.
