Isolation of pristine electronics grade semiconducting carbon nanotubes by switching the rigidity of thewrapping polymer backbone on demand
(American Chemical Society, 2015-09)
Conjugated polymers are among the most selective carbon nanotube sorting agents discovered and enable the isolation of ultrahigh purity semiconducting singled-walled carbon nanotubes (s-SWCNTs) from heterogeneous mixtures ...
Current status, uncertainty and future needs in soil organic carbon monitoring
(2014-01-15)
Increasing human demands on soil-derived ecosystem services requires reliable data on global soil resources for sustainable development. The soil organic carbon (SOC) pool is a key indicator of soil quality as it affects ...

Temperature responsive PEG-based polyurethanes “à la carte”
(Elsevier, 2017-07)
Temperature responsive polymers able to alter their chemical or physical properties have been extensively investigated. Most of these polymers have an alkane polymer backbone with only carbon-carbon bonds. In this sense, ...
Semiconducting single-walled carbon nanotubes on demand by polymer wrapping
(Wiley Vch Verlag, 2013-06)
Efficient selection of semiconducting SWCNTs of large diameter range (0.8-1.6 nm) on demand is demonstrated. Different diameters of SWCNT are systematically selected by tuning the alkyl side-chain lengths of the wrapping ...
Isolamento de fungos da própolis, síntese e biotransformação de clovanos com fungos e avaliação da atividade biológica
(Universidade Federal de Minas GeraisUFMG, 2012-03-30)
In this work it has been isolated 22 strains of fungi exposed to ultravioletradiation using propolis as substrate. In the process of fungal identification it was possible to achieve genera and species for 12 strains. The ...
Infinitene as two fused helicoidal trails of fused rings : evaluation of the magnetic behavior of [12]infinitene and anionic species displaying global aromaticity and antiaromaticity
(2023-02-16)
The unique formation of an infinity-shaped carbon backbone made exclusively from fused benzene rings has recently been achieved. The structure of [12]infinitene can be viewed as two fused [6]helicene structures with a ...
