Chemistry World news article on CrystEngComm enamel regeneration paper

26 Jan 2011

A CrystEngComm Hot article on using nanofibre mats to remineralise tooth enamel has been picked up by the society magazine Chemistry World.

This fascinating paper from Stephen Mann’s group at Bristol University, describes a way to reduce hypersensitivity in teeth.

Highlight: Controlling flexibility in crystal engineering

25 Jan 2011

Here, Christopher Pigge (University of Iowa, US) discusses both the advantages and disadvantages that can arise when using flexible components in crystal engineering. Both organic (mainly triaroylbenzenes) and metal-organic framework systems derived from flexible ligands are reviewed.

HOT Article: Nanofibre mats remineralize tooth enamel

24 Jan 2011

Free to access until Tuesday 15th February 2011!

In this CrystEngComm Hot Article, Stephen Mann and co-workers demonstrate the use of electrospun mats of amorphous calcium phosphate (ACP)/poly(vinylpyrrolidone) (PVP) nano- and microfibres to promote in vitro remineralization of dental enamel and dentine tubule occlusion.

The method is performed under clinically relevant conditions and holds the potential for a new approach to the regeneration of enamel and the alleviation of dentine hypersensitivity.

HOT Article: Use of DFT for physisorption

21 Jan 2011

This latest work from Marcus A. Neumann’s group uses dispersion-corrected density functional theory to look at the energy minimisation of 2,6-bis(2,4-dichlorobenzylidene)cyclohexanone. In this CrystEngComm Hot article they discover that this method predicts the low-temperature phase transition seen in experiment.

As the authors state ‘we believe that DFT-D energy minimisation provides a valuable tool since the calculations have now been shown to be sufficiently reliable to guide experimental studies towards targets most likely to exhibit interesting temperature dependent variation’

HOT article: Micropeonies from nanocrystals

20 Jan 2011

In this HOT article, in CrystEngComm, Chen and co-workers from Harbin Institute of Technology, China report on the morphology and assembly-controlled synthesis of PbTe 3D nanostructures via a facile solvothermal method. They found that the addition of different amounts of glucose can mediate the nucleation and growth of PbTe, resulting in the formation of 3D architectures from 2D nanosheets and nanocrystals. Other factors affecting the morphology such as the amount of NaOH and the volume ratio of ethanol to water, were systematically investigated. The electrical conductivity was also dependent on the morphology.

The striking cover image depicts a vending machine for different layered motifs. In pressing the different molecule buttons, you get either a single layer, bilayer or polar single layer networks (from top to bottom).

Take a closer look at the cover image here.

Alicia Beatty’s group from the Univeristy of Missouri-St Louis, USA, describe the syntheses and crystal structures of lamellar solids constructed from 3,5-pyrazole dicarboxylic acid and amines and that sterically demanding groups impose different hydrogen-bonding connectivity. In the past this combination has resulted in one recurring layer motif.
