Incorporation of graphene oxide and silica fume into cement …

The GO aggregates . Conclusions. In this study, it was found that GO nanosheets aggregated in simulated pore solution if no prevention was employed. The aggregates formed a paper-like structure by cross-linking of calcium ions in the pore solution. Without prevention, GO aggregates were also found in cement paste.Web

Low Friction of Graphene Oxide Aggregates in Lubricant Oil

The low-dispersible GO-dispersed PAO using alkylamine had the lowest friction coefficient of 0.05, as the GO aggregates covered the contact area. From microtribological tests with a load of 0.8 mN as well, it is assumed that the low friction of the GO aggregates originates due to the sliding between the weakest shear layers in the …Web

Graphene Oxide Layer-by-Layer Films for Sensors and Devices

Layer-by-layer films of poly (allylamine hydrochloride) (PAH) and graphene oxide (GO) were characterized, looking at growth with the number of bilayers, morphology, and electrical properties. The PAH/GO films revealed a linear increase in absorbance with the increase in the number of deposited bilayers, allowing the determination that 10.7 ± …Web

Aggregates

Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch sieve. Coarse aggregates are any particles greater than 0.19 inch, but generally range ...Web

Low Friction of Graphene Oxide Aggregates in Lubricant Oil …

Many GO aggregates were found in the low-dispersible GO-dispersed PAO, which arose from the high concentrations of the oxygen functional groups. These aggregates occasionally entered and covered the friction interface. The frictional force was low only at that particular time. Especially the frictional coefficient of the GO aggregates …Web

With increasing concentration, GO self-assembled into 2D macro-aggregates to form a nematic LC phase. In addition, the local deformations (wrinkles, bending) imply the remarkable flexibility of GO-aggregates. Prior to lyophilization, it appeared to form an interconnected GO phase (virtually bicontinuous phase) that was evenly dispersed in water.Web
