“…This trend is minor dependent on the sizes of shell units. The calculated crystalline sizes agree with experimental data obtained from XRD and Raman spectra, where the sizes of graphite layers are 2-4 nm and the heights of crystallites are 1.1-2.0 nm corresponding to 3-6 parallel layers [18,26,32,[51][52][53].…”

“…In accordance to the HRTEM observation, the individual graphite layer in primary carbon is indeed the basic building unit, instead of graphite crystallites concluded from XRD and Raman measurements [18,19,28,29]. The graphite layers are arrays arranged in a concentric fashion with significant distortion presumably due to the presence of impurities such as oxygen, sulfur, etc.…”

“…In contrast to the low carbon composition (<60%) of soot or black carbon, carbon black material consists mostly of elemental carbon (>97%) in the form of nearly spherical particles of colloidal size less than 100 nm that are further fused together as aggregates in the size of hundreds nanometers. A number of aggregates can interact via van der Waals forces to form a secondary structure known as agglomerates in the scale of micrometers [18,19]. The important properties of carbon black include surface chemistry, surface area, porosity, particle size, microstructure and so on.…”

“…Lattice fringes often cross entire grains, providing evidence that these crystals are not mixtures of disordered graphite, graphene, and graphane, as observed in other natural and anthropogenic nanoscale carbons (e.g., refs. [37][38][39][40][41][42]. A number of other internal textures were observed.…”

Significance In 2007, scientists proposed that the start of the Younger Dryas (YD) chronozone (10,900 radiocarbon years ago) and late Pleistocene extinctions resulted from the explosion of a comet in the earth’s atmosphere. The ET event, as it is known, is purportedly marked by high levels of various materials, including nanodiamonds. Nanodiamonds had previously been reported from the Bull Creek, Oklahoma, area. We investigate this claim here by quantifying the distribution of nanodiamonds in sediments of different periods within the Bull Creek valley. We found high levels of nanodiamonds in YD boundary deposits, supporting the previous claim. A second spike in nanodiamonds during the late Holocene suggests that the distribution of nanodiamonds is not unique to the YD.

“…In a single CB particle, small crystallites are randomly oriented, which is different from graphite. The fundamental units are aggregates comprised of particles but the particles appear to be continuous on the lattice scale within the same aggregate [36,37]. The molecule structure of CB [37].…”

Transform Infrared Spectroscopy (FTIR) test were conducted to evaluate the anti-UV ageing effects of the three UV blocking modifiers. Physical property tests show that base asphalt was influenced more seriously by UV radiation compared to the modified asphalt. DSR test results indicate that the complex modulus of asphalt before UV ageing is increased because of modifiers, while the complex modulus of base asphalt after UV ageing is higher than that of the modified asphalt, which shows that the UV blocking modifiers promote the antiageing effects of asphalt. FTIR test reveals that the increment of carbonyl groups and sulfoxide groups of modified asphalt is less than that in base asphalt. Tests indicate the best UV blocking effect results for samples with LDHs and the worst UV blocking effect results for samples with CB.
