“…At the same time, the surface wettability of self-assembly materials can also reflect the self-assembly process. [79] The surface wettabilities of film NE1 from solution in DMF, and xerogels film NE2-NE3 from DMF were investigated via water contacting angle experiment. Film NE1 from DMF exhibited the hydrophobicity with the contacting angle of 121°( Figure 8a).…”

Three naphthalimide‐based gelators (NE1,NE2, NE3) with corresponding one, two and three N‐undecanoic acid methylester‐1,8‐naphthalimide were designed and synthesized (the abbreviation NE1‐NE3, N assigned to the naphthalimide, E assigned to ester, and numerber representing the number of N‐undecanoic acid methylester‐1,8‐naphthalimide) The different number of 1, 8‐naphthalimide groups in gelator endowed them with the different central groups, conjugated structures and steric configurations, which could bring different self‐assembly abilities and behaivors. The self‐assembly processes of three gelators in different solvents were characterized by multiple characterization technologies. The gelation ability, self‐assembly structure, fluorescence emission behavior, material surface wettability of this system could be regulated by the number of 1, 8‐naphthalimide groups. Gelator NE1 possessed the best gelation ability among three gelators, and the self‐assembly structures in gels NE1 from different solvents were completely different from that of gels NE2 and NE3. In addition, surface wettability of film NE1 exhibited the highest hydrophobicity under the same condition. Fluorescence emission behavior of this system could be tuned by the number of 1, 8‐naphthalimide groups solvent and gel state. At the same condition, the absorbance at the same band was gradually decreased with the number of 1, 8‐naphthalimide groups increasing. This work will provide a new design way for construction of functional supramolecular self‐assembly process.

“…All samples display some common absorption bands such as the broad band observed around 3435 cm À 1 related to the stretching vibration of free OH and chemisorbed water molecules on both Ni doped and free CX surfaces. The bands observed at 1737 and 2922 cm À 1 are corresponding to the stretching vibrations of C=O moieties in lactones, carboxylic and ester [21] and CÀ H bonds, [22] respectively for the CX network. [21a,23] The band observed at 1635 cm À 1 for the Ni-0/CX sample is related to the OH bending vibration mode of adsorbed water molecules.…”

In this work, the synergism between the nano nickel particles and its carbon xerogel support, CX, together with their graphite substrate, G, leads to an efficient Nickel/CX/G electrode for electrocatalysis of ethanol oxidation reaction, EOR. The preparation conditions are optimized. The optimum electrode is made of 6 % weight of Ni doped in CX matrix and drop‐casted on a graphite surface, Ni‐6/CX/G. The catalyst structure and morphology are investigated using XRD, SEM, TEM and FTIR techniques. The electrochemical activity towards EOR is tested in 1 M NaOH+1 M Ethanol solutions by cyclic voltammetry combined with a rotating ring disk electrode. The optimum electrode shows an oxidation peak current density value of 5925 normalA.gnormalNnormali-1 ${{\rm A}.{{\rm g}}_{{\rm N}{\rm i}}^{-1}}$ and considerable stability. This electrode may serve as a good candidate for the anode in the Direct Alkaline Ethanol Fuel Cell, DAEFC.
