Synthesis of carbon 'onions' in water
TL;DR: A simple method for producing high-quality spherical carbon nano-'onions' in large quantities without the use of vacuum equipment is described, which is economical and environmentally benign, and produces uncontaminated nanoparticles which may be useful in many applications.

TL;DR: In this article, the position of the G peak and the appearance of transverse optic phonon peaks of carbon onions have been identified in terms of the Raman spectrum from carbon onions, and the curvature of the graphene planes is invoked to explain the relaxation of Raman selection rules and appearance of the new peaks.

Carbon onions: carriers of the 217.5 nm interstellar absorption feature.
TL;DR: The similarities between the experimental and observed absorption spectra indicate that carbon onions are very strong candidates for the origin of the UV interstellar absorption peak at 4.6 microm(-1), a key feature of the interstellar spectrum.
Fabrication of inorganic molybdenum disulfide fullerenes by arc in water
Noriaki Sano,Haolan Wang,Manish Chhowalla,Ioannis Alexandrou,Gehan A. J. Amaratunga,Masakazu Naito,Tatsuo Kanki +6 more
TL;DR: In this paper, a model based on the agglomeration of MoS2 fragments over an extreme temperature gradient around a plasma ball in water is proposed to explain the formation of nano-particles.

Pritesh Hiralal,Pritesh Hiralal,Haolan Wang,Husnu Emrah Unalan,Yinglin Liu,Markku Rouvala,Di Wei,Piers Andrew,Gehan A. J. Amaratunga +8 more
TL;DR: In this paper, a thin film supercapacitors made of random networks of single-walled carbon nanotubes (SWNTs) were enhanced by the use of carbon nanoparticles of a size ideal to fill the pores in the SWNT network.
