T-Carbon: A Novel Carbon Allotrope
Physical Review Letters, 2011 A structurally stable crystalline carbon allotrope is predicted by means of the first-principles calculations. This allotrope can be derived by substituting each atom in diamond with a carbon tetrahedron, and possesses the same space group Fd^1 3m as diamond, which is thus coined as T- carbon. The calculations on geometrical, vibrational and electronic

Carbon nanofibers based carbon–carbon composite fibers
Discover Nano, 2023 AbstractTextile grade polyacrylonitrile (PAN) was used as a precursor material for carbon fiber preparation. E-beam irradiated polyacrylonitrile grafted carbon nanofibers were dispersed in polyacrylonitrile solution (dissolved in dimethyl formamide).

Embodied Carbon Accounting through Spatial-Temporal Embodied Carbon Models [PDF]
arXiv, 2023 Embodied carbon is the total carbon released from the processes associated with a product from cradle to gate. In many industry sectors, embodied carbon dominates the overall carbon footprint. Embodied carbon accounting, i.e., to estimate the embodied carbon of a product, has become an important research topic.

Journal of Magnetic Resonance (1969), 1985 Nowadays many possibilities exist to elucidate carbon-carbon connectivity. In hydrogen-bearing carbon systems C-C connectivities can be traced out most conveniently in an indirect way by a combination of H-H COSY (I) and H-C CQSY (2). In case of overlapping ‘proton signals ambiguities can be removed by heteronuclear relayed spectroscopy (3) and ...

Trade in Carbon and Carbon Tariffs [PDF]
Environmental and Resource Economics, 2021 AbstractCarbon-based import tariffs are proposed as a policy measure to reduce carbon leakage and increase the global cost-effectiveness of unilateral CO2emission pricing. We investigate the case for carbon tariffs. For our assessment, we combine multi-region input–output and computable general equilibrium analyses based on data from the World Input ...

Carbon Nanomaterials to Combat Virus: A perspective in view of COVID-19 [PDF]
, 2020 The rapid outbreaks of lethal viruses necessitate the development of novel antiviral substance. Besides the conventional antiviral substances, biocompatible nanomaterials also have significant potential in combating the virus at various stages of infection.

Northern Peatlands: Role in the Carbon Cycle and Probable Responses to Climatic Warming.
Ecological Applications, 1991 Boreal and subarctic peatlands comprise a carbon pool of 455 Pg that has accumulated during the postglacial period at an average net rate of 0.096 Pg/yr (1 Pg = 1015 g). Using Clymo's (1984) model, the current rate is estimated at 0.076 Pg/yr.

Carbon Pricing and the Transition from Voluntary to Mandatory Markets [PDF]
, 2008 The current national and global call for a coordinated and meaningful response to climate change concerns is certain to shift the United States from several regional and voluntary carbon markets today to a global compulsory market in the near future.

Is the Thatcher Illusion Modulated by Face Familiarity? Evidence from an Eye Tracking Study. [PDF]
PLoS ONE, 2016 Thompson (1980) first detected and described the Thatcher Illusion, where participants instantly perceive an upright face with inverted eyes and mouth as grotesque, but fail to do so when the same face is inverted.
