Theoretical exploration of MgH2 and graphene nano-flake in cyclohexane: proposing a new perspective toward functional hydrogen storage material

06-Jan-2015 | Runze Liu; Yinghe Zhao; tianshu chu, Chemical Communication, 2015

We studied the reaction mechanism of di-n-butylmagnesium decomposing into MgH2 in cyclohexane, and found a new route easier than famous β-hydride elimination. Further, we explored the dynamic behavior of graphene nano-flake and MgH2 in cyclohexane, and gained new insights for efficient hydrogen ...

Solution and solid-phase halogen and C–H hydrogen bonding to perrhenate

06-Jan-2015 | Casey J. Massena; Asia Marie S. Riel; George F. Neuhaus; Daniel A. Decato; Orion B. Berryman, Chemical Communication, 2015

1H NMR spectroscopic and X-ray crystallographic investigations of a 1,3-bis(4-ethynyl-3-iodopyridinium)benzene scaffold with perrhenate reveal strong halogen bonding in solution, and bidentate association in the solid state. A nearly isostructural host molecule demonstrates significant C–H ...

Glucose Transport Machinery Reconstituted in Cell Models

31-Dec-2014 | Jesper s Hansen; Karin Elbing; James Russell Thompson; Noah Malmstadt; Karin Lindkvist-Petersson, Chemical Communication, 2014

Here we demonstrate the production of a functioning cell model by formation of giant vesicles reconstituted with the GLUT1 glucose transporter and a glucose oxidase and hydrogen peroxidase linked fluorescent reporter internally. Hence, a simplified artificial cell is formed that is able to take ...

Geminal dihalogen isosteric replacement in hydrated AI-2 affords potent quorum sensing modulators.

30-Dec-2014 | Min Guo; Yue Zheng; Jessica Terrell; Michal Ad; Clement Opoku-Temeng; William E. Bentley; Herman O Sintim, Chemical Communication, 2014

Hydrated carbonyl groups in AI-2, a quorum sensing autoinducer, make key hydrogen bonding interactions in the binding site of LsrR (a transcriptional regulator). This can be recapitulated with geminal dibromides, via halogen bonding. Geminal dihalogens represent interesting isosteric replacements ...

Ethanol Induces the Formation of Water-Permeable Defects in Model Bilayers of Skin Lipids

30-Dec-2014 | Romnik Thind; David W O'Neill; Annalaura Del Regno; Rebecca Notman, Chemical Communication, 2014

We show that ethanol can induce the formation of water-permeable defects in model membranes of skin, providing a fresh perspective on ethanol as a membrane modulator. We rationalise our findings in terms of the chemical nature of ethanol, i.e., a combination of its hydrogen bonding propensity and ...

Synthesis, structure and dehydrogenation of zirconium borohydride octaammoniate

30-Dec-2014 | Jianmei Huang; Yingbin Tan; Jiahao Su; Qinfen Gu; Radovan Černý; Liuzhang Ouyang; Dalin Sun; Xuebin Yu; Min Zhu, Chemical Communication, 2014

A new metal borohydride ammoniate (MBA), Zr(BH4)4·8NH3, was synthesized via ammoniation of the Zr(BH4)4 crystal. Zr(BH4)4·8NH3 has a distinctive structure and the highest coordination number of NH3 groups among all the known MBAs. This compound could quickly dehydrogenate at 130 °C, enabling it a ...

Introduction of a mediator for enhancing photocatalytic performance via post-synthetic metal exchange in metal–organic frameworks (MOFs)

30-Dec-2014 | Dengrong Sun; Wenjun Liu; Mei Qiu; Yongfan Zhang; Zhaohui Li, Chemical Communication, 2014

Ti-substituted NH2-Uio-66(Zr/Ti) prepared by using a post-synthetic exchange (PSE) method showed enhanced photocatalytic performance for both CO2 reduction and hydrogen evolution under visible light. Density functional theory (DFT) calculations and electron spin resonance (ESR) results reveal ...

Hydrogen bond distinction and activation upon catalytic etherification of hydroxyl compounds

25-Dec-2014 | Penghua Che; Fang Lu; Xin Nie; Yizheng Huang; Yanliang Yang; Feng Wang; Jie Xu, Chemical Communication, 2014

An excellent linear correlation between ln [ ] δ (OH chemical shift) and 1/T (temperature) is discovered for the first time for hydroxyl compounds. The derived slope (A) provides information as an index not only for distinguishing different types of H-bonds, but also for predicting their ...

Engineering Supramolecular Organic Frameworks (SOFs) of C-alkylPyrogallol[4]arene with Bipyridine-based Spacers

25-Dec-2014 | Rahul S Patil; Harshita Kumari; Charles L Barnes; Jerry L Atwood, Chemical Communication, 2014

Supramolecular organic frameworks (SOFs) based on pyrogallol[4]arene and 4,4’-bipyridine-type spacer molecules have been investigated. The hydrogen bonding pattern and molecular arrangement in the crystal structures are engineered through the cocrystallization approach. The length of the spacer ...

Excellent catalytic effects of multi-walled carbon nanotubes supported titania on hydrogen storage of Mg-Ni alloy

24-Dec-2014 | Liquan Li; Yajun Tan; Yunfeng Zhu, Chemical Communication, 2014

Superior catalytic effects of multi-walled carbon nanotubes supported titania synthesized by sol–gel method on hydrogen storage of Mg-Ni alloy were investigated. The excellent hydrogen storage properties were obtained: absorbed 5.60 wt.% H2 within 60 s at 373 K and released 6.08 wt.% H2 within ...
