Graphene oxide liquid crystal Pickering emulsions and their assemblies

Janus graphene oxide nanosheets prepared via Pickering emulsion template

“…As we know, the asymmetric structure of Janus particles is commonly difficult to be characterized, especially for extremely thin 2D particles because they tend to stack to conceal their surface during drying. It has been reported that the thickness of polyetheramine-modified GO is affected by the length of polymer chains according to XRD measurements [56][57][58]. Herein, poly(propylene glycol) bis(2-aminopropyl ether) with average molecular weights of ∼2000 (D2000) was chosen to functionalize GO nanosheets.…”

Roles of surface chemistry and structural defects of activated carbons in the oxidative desulfurization of benzothiophenes

“…In addition to the surface-bound percarboxylic acid hypothesis, we considered carbon particle stabilization of fuel/water emulsions to explain the observed trends. Partly hydrophilic activated carbon particles (as the effective carbons should be based on their high surface oxygen content) would be more likely to reside at the fuel-water interface than fully hydrophobic particles (as the ineffective carbons would be) [84][85][86][87][88]. Specifically relevant to the activated carbon work, Kim et al [86] recently reported the use of graphene oxide as a molecular-colloidal surfactant, citing the importance of both graphene edges and carboxylic sites as the source of its amphiphilic properties.…”

Synthesis of ethylene glycol-treated Graphene Nanoplatelets with one-pot, microwave-assisted functionalization for use as a high performance engine coolant

“…Since the thermal conductivity of metal and carbon based nano-particles are significantly higher than the conventional base-fluids, their suspension can significantly increase the effective thermal properties of the working fluids [13][14][15]. Recently along this line, a new class of fluid mixtures containing nanostructures has been introduced to overcome the issues caused by low thermal conductivity of coolants [16][17][18].…”
