New Coaxial Nanocables Show Enhanced Rate, Energy and Cycling Performance as Li-ion Electrode Materials; “Yin-Yang Principle” Extensible to Other Electrochemical Storage Devices

Comparison of the rate performance of CNT@TiO2, TiO2-free CNT, and CNT-free TiO2 sample between voltage limits of 0.01-3 V. Shaded areas represent the capacity contribution from TiO2 or CNT in the nanocables. Credit: ACS, Cao et al. Click to enlarge.

Researchers in China and Germany have coated carbon nanotubes (CNT) with a nanoporous layer of TiO2 to create coaxial nanocables for use as electrode materials in Li-ion batteries (LIB). The CNT@TiO2 coaxial nanocables show excellent rate capability, energy and cycling performance compared with both pure CNT and pure TiO2 when used as anode materials for LIBs.

Both the specific capacity in the CNT core and that in the TiO2 sheath are much higher than that of the TiO2-free CNT and that of the CNT-free TiO2 sample, respectively. A paper on the work was published online 22 January in the ACS journal Chemistry of Materials.

UK Climate Secretary Declares a “Battle” Against Climate Deniers

In an exclusive interview with the UK Guardian’s Observer, UK climate secretary Ed Miliband declared a “battle” against the “siren voices” who denied global warming was real or caused by humans, or that there was a need to cut carbon emissions to tackle it.

Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Decadal warming rates arising from (i) greenhouse gases and aerosols alone (black); (ii) that obtained including the stratospheric water decline after 2000 (red); and (iii) including both the stratospheric water vapor decline after 2000 and the increase in the 1980s and 1990s (cyan). Credit: Solomon et al., Science. Click to enlarge.

A 10% drop in stratospheric water vapor concentrations acted to slow the rate of increase in global surface temperature over 2000-2009 by about 25% compared to that which would have occurred due only to CO2 and other greenhouse gases, according to a new study by researchers from NOAA Earth System Research Laboratory; the University of Colorado, Boulder; and the University of Bern (Switzerland). Their paper was published online in the journal Science on 28 January.

Earlier observations from satellites and balloons suggest that stratospheric water vapor probably increased between 1980 and 2000, which would have enhanced the decadal rate of surface warming during the 1990s by about 30% compared to estimates ignoring this change, according to the authors.

Dupont Danisco Opens Cellulosic Ethanol Demonstration Facility

Leaders from DuPont Danisco Cellulosic Ethanol (DDCE), University of Tennessee and Genera Energy cut the ribbon on a cellulosic ethanol demonstration facility in Vonore, Tenn. The 74,000-square-foot plant has started producing ethanol and will deliver low-cost, fully-integrated technology for commercial production of ethanol from agricultural residue and bioenergy crops, including corncobs and switchgrass.

The plant combines pretreatment technology based on DuPont’s advanced mild alkaline technology and low-cost enzyme technology for saccharification, based on Danisco’s protein engineering innovation and commercial scale enzyme production expertise. An innovative ethanologen based on DuPont Zymomonas technology delivers high performance sugars co-fermentation for optimal process and yields.
