GO is an electrically insulating material due to its disrupted sp2 bonding networks, but it can act as semiconductor, depending on the degree of oxidation (Dreyer et al., 2009).Moreover, GO shows a high specific surface area (890 m 2 g −1) (Bradder et al., 2011) and mechanical strength (Young's modulus of ~1.0 and breaking strength of ~130 …
The GO aggregates entrap free water molecules, thereby affecting the rheological properties of cement mixture. In order to provide the appropriate workability of composites and the sufficient dispersion of GO in alkaline cement environment, two main approaches have been proposed.
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 …
Aggregate is an important tactical pattern in DDD, which helps to maintain the consistency of our business objects. However, the idea of aggregate is also useful outside of the DDD context. There are numerous business cases where this pattern can come in handy. As a rule of thumb, we should consider using aggregates when there are multiple ...
Then, the effects of GO aggregates on the degree of hydration, sorptivity, and tensile strength of cement paste were investigated. The aspect ratio of GO aggregates is much larger than that of the original GO nanosheets. Compared to plain cement paste, the increase of non-evaporable water content of the cement paste was found to be very …

The GO-aggregates interaction is key to understanding the behaviors of sand pre-saturated by GO solution. The following experiment was designed and conducted to shed light on this interaction because it is difficult to directly observe the coated GO on the sand in the cementitious matrix.

In this study, the aggregation kinetics, aggregate morphology, and aggregation mechanisms of graphene oxide (GO) in the presence of Cs+, Sr2+, UO22+, Eu3+, or Th4+ are characterized by using time-resolved dynamic light scattering, transmission electron microscopy (TEM)-element mapping, redispersion of GO …
As found from SEM-EDS observation of GO and TEA-GO aggregates (Fig. S1), the decreased –C–O–C– groups on GO reduced the intercalation complexation between GO and Ca 2+, causing single-layer GO aggregates. Meanwhile, the additional −OH groups from TEA avoided deoxygenation in highly alkaline solution and kept …
In the presence NOM and divalent cations (Ca2+, Mg2+), GO aggregates settle from suspension due to GO functional group bridging with NOM and divalent ions. However, rGO-1h and rGO-2h remain ...
GO aggregates were retained in many organelles, such as the eyes, heart, yolk sac, and tail of the embryos, and apoptosis and reactive oxygen species (ROS) generation were observed in these regions . The GFNs exert different toxicological effects on male or reproductive system.

The GO aggregates were described in the study of Park et al. [12] as GO paper modified by divalent ions. In current study, it was found that the aggregates were not stable under shear mixing, although severe aggregation occurred when GO was introduced into Ca(OH) 2 solution. Large GO aggregates could be broken into small aggregates …
Aggregate aims to publish on a wide variety of topics that focus on the processes of aggregation of atoms, ions, molecules, oligomers, polymers, clusters, particles, gels, hybrids, composites, cells, pathogens, etc. in a broad range of areas such as chemistry, physics, materials, engineering, biology, life science and so forth.
This study suggests that natural resources such as river sand and water can be replaced with sea sand and sea water in reasonable amounts and that cement can be partially replaced with graphene oxide (GO), in order to reduce the depletion of these resources caused by increased construction activity. Tests for workability such as fluidity, …
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 …

Similarly, GO is seen a potential adsorbent for the removal of environmental contaminants, for example through the formation of nanoparticulate aggregates containing radionuclides 7.
These large-sized GO aggregates consist of multilayer graphite flakes which are oxidized on the outer layers, while the inner layers consist of pristine or mildly oxidized graphene sheets. Intercalation-exfoliation of these GO aggregates by tetrabutylammonium cations yields large-sized conductive graphene sheets (mean sheet area of 330 +/- 10 ...

Gene ontology (GO) enrichment analysis is frequently undertaken during exploration of various -omics data sets. Despite the wide array of tools available to biologists to perform this analysis, meaningful visualisation of the overrepresented GO in a manner which is easy to interpret is still lacking. Monash Gene Ontology (MonaGO) is a novel …
To better investigate the dispersibility of GO in saturated Ca(OH) 2 and CaCl 2 solutions, optical microscope photos were taken and the results are presented in Fig. 2. Fig. 2 (a) illustrates the optical microscope photograph of the GO aqueous solution. Due to the limitation of the resolution, optical microscopy can not resolve GO nanosheets, …
