“…[12] Owing to their unique thermal transport properties, the have been studied in biomedicine and corrosion prevention. [13] Synthesis of erucamide currently involves the reaction of ammonia and amines with fatty acids under catalysis and the usage of microwave irradiation to synthesize amides from simple short-chain esters (C 4 -C 10 ) and formamide. [14] Recently, the photo-fenton method was used to synthesize erucamide at room temperature from the existing reagent, acetonitrile.…”

Abstract2D organic crystals play a unique role in photodetection owing to their tunable detection wavelength, low manufacturing cost, compatibility with lightweight, and controllable synthesis. However, their detection wavelength range mainly encompasses the visible (Vis) and near‐infrared (NIR) spectra. Herein, 2D erucamide crystals are synthesized using nitrogen gas and methanol as raw materials without catalysts at room temperature under atmospheric pressure via laser processing. The synthesized 2D erucamide is demonstrated to be a promising broad bandgap organic semiconductor material. A UV photodetector made of 2D erucamide exhibited a responsivity as high as 145 mA W−1, a millisecond‐level response speed, and an excellent detectivity of 4.96 × 109 Jones. Furthermore, the synthesized erucamide showed an excellent UV–vis suppression ratio (R254 nm/R532 nm) of 59. The synthesis mechanism of erucamide via laser bubbling in liquids is proposed. Thermodynamically, the high temperature of the bubbles is beneficial for nitrogen and methanol decomposition. Kinetically, rapid bubble quenching facilitates final product formation. This accomplishment represented the pioneering utilization of lasers in converting nitrogen gas into organic compounds while introducing 2D erucamide into the realm of organic UV photodetectors.

“…Velázquez JDH et al [22] linked erucamide to the graphene sheet and found that erucamide chains tend to remain closer together through pi-pi stacking interactions arising from the double bonds located at C 13 -C 14 , and that this arrangement of erucamide chains was responsible for the lower friction coefficient of erucamide brushes, which was a macroscopic consequence of cooperative quantum mechanical interactions. Di YY et al [23] added erucamide to a self-assembled film (SAF) to prepare erucamide SAFs. When erucamide was laid on the surface of the SAF, it showed obvious atomic stick-slip friction behavior and ultra-low frictional dissipation.…”

To evaluate the impact of various proportions of erucamide and N-phenyl-α-naphthylamine on grease’s tribological performance for roller bearings, lithium complex grease (LCG) and polyurea grease (PG) were prepared with erucamide and N-phenyl-α-naphthylamine proportions of (0,0), (0,3), (1,2), (2,1), and (3,0). An investigation was conducted into the microscopic structures of the ten greases and their effects on the friction coefficients and wear scars of GCr15 steel. These findings were validated through bearing friction torque tests. The results indicate that the addition of 2 wt. % erucamide and 1 wt. % N-phenyl-α-naphthylamine to PG/LCG significantly enhances their tribological properties and reduces friction torque, with PG exhibiting superior performance. This enhancement was attributed to the synergistic interaction of erucamide and N-phenyl-α-naphthylamine with the lamellar thickener within PG. Erucamide contributed to friction reduction, while N acted as an antioxidant.

“…The memristor, short for memory resistor, is considered the fourth class of electrical circuits useful for neuromorphic computing in artificial intelligence. − The giant success of semiconductor memristors makes in-memory computing come true, ,− in particular now boosted by 2D materials − and flexible electronics. , As the brain is made of memristors, − it is advanced in low energy consumption and highly efficient computing/memory . Thus, the emergence of nanofluidic memristors is a step forward to the biology synapse; at least the signaling relies on hydrated ions in soft matter rather than electrons/holes in solid electronics …”
