One-step synthesis of Ag–reduced graphene oxide–multiwalled carbon nanotubes for enhanced antibacterial activities

16-Apr-2015 | Leila Shahriary; Roopa Nair; Sushma Sabharwal; Anjali A. Athawale, New Journal of Chemistry, 2015

The present study reports a rapid one-step preparation of Ag nanoparticles decorated reduced graphene oxide–multiwalled carbon nanotube hybrids (Ag–rGO–MWCNTs) by heating a mixture of graphene oxide (GO), acid functionalized multiwalled carbon nanotubes (f-MWCNTs), and an aqueous solution of ...

Predicting accurate absolute binding energies in aqueous solution: thermodynamic considerations for electronic structure methods

16-Apr-2015 | Jan H. Jensen, Physical Chemistry Chemical Physics, 2015

Recent predictions of absolute binding free energies of host-guest complexes in aqueous solution using electronic structure theory have been encouraging for some systems, while other systems remain problematic. In this paper I summarize some of the many factors that could easily contribute 1-3 ...

Structure determination of bound nitrogen-based adducts with copper(II) acetylacetonato; an EPR, ENDOR and DFT study

15-Apr-2015 | Emma Carter; Katherine M. Sharples; James A. Platts; Damien M. Murphy, Physical Chemistry Chemical Physics, 2015

The adducts of bis(acetylacetonato)–copper(ii), [Cu(acac)2], formed with a range of nitrogen heterocycles including pyridine (2), methylpyridines (3,4,5), amino-methylpyridines (6,7) and diazines (8,9,10) were investigated in frozen solution using X-band EPR and 1H ENDOR spectroscopy. The small ...

Cyano- and chloro-substituted coronene diimides as solution-processable electron-transporting semiconductors

15-Apr-2015 | Chenhao Zhang; Ke Shi; Kang Cai; Jiajun Xie; Ting Lei; Qifan Yan; Jie-Yu Wang; Jian Pei; Dahui Zhao, Chemical Communication, 2015

3,4,9,10-Tetracyano- and tetrachlorocoronene-1,6,7,12-tetracarboxy diimides with low LUMO levels at −3.9 to −4.2 eV are developed. These molecules manifest potent n-type semiconductive capability in solution-processed field-effect transistors, with electron mobilities of up to 0.16 cm2 V−1 s−1 ...

Controlled synthesis of monodisperse [small alpha]-calcium sulfate hemihydrate nanoellipsoids with a porous structure

15-Apr-2015 | Guangming Jiang; Qiaoshan Chen; Caiyun Jia; Sen Zhang; Zhongbiao Wu; Baohong Guan, Physical Chemistry Chemical Physics, 2015

We report a facile and green chemical solution approach to synthesize monodisperse α-calcium sulfate hemihydrate (α-HH) nanoellipsoids with a length of 600 nm and a width of 300 nm by simply mixing Ca2+ and SO42− glycerol–water precursor solutions in the presence of Na2EDTA. The α-HH ...

Collisional relaxation of apocarotenals: identifying the S* state with vibrationally excited molecules in the ground electronic state S0*

15-Apr-2015 | Florian Ehlers; Mirko Scholz; Jens Schimpfhauser; Jürgen Bienert; Kawon Oum; Thomas Lenzer, Physical Chemistry Chemical Physics, 2015

In recent work, we demonstrated that the S* signal of β-carotene observed in transient pump–supercontinuum probe absorption experiments agrees well with the independently measured steady-state difference absorption spectrum of vibrationally hot ground state molecules S0* in solution, recorded at ...
