“…[4,6] To mitigate these challenges, promising renewable alternatives from bio-derived feedstocks have gained momentum. [7][8][9][10][11][12][13][14] Bio-based feedstocks can result in a nearly "closed carbon balance" through CO 2 capture during photosynthesis and have unique functional groups that enable site-specific chemistries during processing.…”

“…However, the origin of functional characteristics of the bio-oils is poorly understood and their use is limited to as-received, cold-pressed or refined liquids. Improvement in the lubrication characteristics of renewable lubricants is, therefore, highly desirable with multiple efforts being dedicated to this goal 17–19 .…”

Design of environmentally friendly lubricants derived from renewable resources is highly desirable for many practical applications. Here, Orychophragmus violaceus (Ov) seed oil is found to have superior lubrication properties, and this is based on the unusual structural features of the major lipid species—triacylglycerol (TAG) estolides. Ov TAG estolides contain two non-hydroxylated, glycerol-bound fatty acids (FAs) and one dihydroxylated FA with an estolide branch. Estolide branch chains vary in composition and length, leading to their thermal stability and functional properties. Using this concept, nature-guided estolides of castor oil were synthesized. As predicted, they showed improved lubrication properties similar to Ov seed oil. Our results demonstrate a structure-based design of novel lubricants inspired by natural materials.

“…Rh−Ir−ReO x /SiO 2 has the potential for higher activity in the hydrogenation of FUR to tetrahydrofurfuryl alcohol intermediate in the low‐temperature step than that with Ir−ReO x /SiO 2 , although the hydrogenation activity was lower than that of Pd−Ir−ReO x /SiO 2 . In recent years, the capability of Ir−ReO x /SiO 2 as a versatile catalyst was explored for derivatizing lubricant base oil of C 22 –C 34 with unprecedented control, the preparation of 1,3‐propanediol through selective C−O bond rupture of glycerol, and HDO of vegetable oil with C 14 –C 18 . As part of upgrading, a MoO x ‐modified Ir/SiO 2 catalyst, with a Mo/Ir ratio of 0.13 (Ir−MoO x /SiO 2 ), exhibits the highest product yield (78–96 %) under mild reaction conditions for the production of jet and diesel fuels and lubricant oils .…”

He has more than 10 years of professional academic research experience in nano-and biocatalysis, porous and framework materials, and electrochemistry.T he last eight years of his research has centered on the chemistry of lignocellulose, lignocellulose-derived materials, enzymatic processes, and understanding of their chemical reaction networks. He is currently interested in biocomposite materials research for therapeutic and related applications. This also includes materials for electrochemical energy generation and biomass-derived novel materials for advanced applications. Figure 2.
