Room-temperature synthesis of various allotropes of carbon nanostructures (graphene, graphene polyhedra, carbon nanotubes and nano-onions, n-diamond nanocrystals) with aid of ultrasonic shock using ethanol and potassium hydroxide

Carbon-Based Nanoparticles and Their Surface-Modified Counterparts as MALDI Matrices

“…159 Synthesis of NDs could be achieved using different techniques such as high pressure/high temperature, ultrasonic synthesis, grinding, and detonation. 160,161 The particle size, shape, and surface structure of the NDs are highly affected by their synthesis method. For instance, the NDs resulting from the detonation process are smaller, have higher surface area, and higher impurity content, while the grinding technique generates larger particles with broad particle size distribution, higher purity, and flat surfaces.…”

Application of carbon allotropes composites for targeted cancer therapy drugs: A review

“…Among these, because of the unique physicochemical properties of nanostructured carbon materials such as graphene, nanodiamonds, fullerenes, and CNTs, they are highly investigated to tumor theranostics from the various aspects, for example, their engineering possibility for practical therapeutics matters and multi-function diagnostics [34,35]. Within a live body, nanoparticles comprising carbon allotropes have a distinct behavior, distribution pathway, and toxicity [36,37]. Some of these carbon allotropes show extremely photothermal impacts due to their capability to absorb the near-infrared radiation (NIR), a feature that can be applied to the in situ killing of cancer cells in a short time [38,39].…”

Formation and growth characteristics of nanostructured carbon films on nascent Ag clusters during room-temperature electrochemical CO2 reduction

“…In a recent study by Dai et al , 9 various carbon nanostructures were synthesized under ambient conditions with ethanol as the carbon source, using KOH and ultrasonic shock. The carbon nanostructures were grown directly from the carbon atoms and small carbon groups, which were formed in the solution.…”

“…1,2 The commercial main-stream production of SCAs, however, has relied on either pyrolysis, chemical vapor deposition, arc discharge, laser ablation, or exfoliation, each of which display major shortcomings due to being energyintensive. [3][4][5][6][7][8] In a recent study by Dai et al, 9 various carbon nanostructures were synthesized under ambient conditions with ethanol as the carbon source, using KOH and ultrasonic shock. The carbon nanostructures were grown directly from the carbon atoms and small carbon groups, which were formed in the solution.…”
