Multistate treatments of the electronic coupling in donor-bridge-acceptor systems: insights and caveats from a simple model.

The journal of physical chemistry. A

Cave RJ, Newton MD.
PMID: 24266545
J Phys Chem A. 2014 Sep 04;118(35):7221-34. doi: 10.1021/jp408913k. Epub 2013 Dec 10.

We use a simple one-dimensional delta function electronic structure model (dfm) to investigate the results of a pair of multistate diabatization techniques (i.e., based on n states, with n ≥ 2) for linear DBA and DBBA (donor-bridge-acceptor) electron-transfer systems....

Comparison of Relative Activation Energies Obtained by Density Functional Theory and the Random Phase Approximation for Several Claisen Rearrangements.

The journal of physical chemistry. B

Hartley MK, Vine S, Walsh E, Avrantinis S, Daub GW, Cave RJ.
PMID: 26308793
J Phys Chem B. 2016 Mar 03;120(8):1486-96. doi: 10.1021/acs.jpcb.5b06646. Epub 2015 Sep 01.

We investigate several representative density functional theory approaches for the calculation of relative activation energies and free energies of a set of model pericyclic reactions, some of which have been studied experimentally. In particular, we use a standard hybrid...

Self-sorted photoconductive xerogels.

Chemical science

Draper ER, Lee JR, Wallace M, Jäckel F, Cowan AJ, Adams DJ.
PMID: 28451108
Chem Sci. 2016 Oct 01;7(10):6499-6505. doi: 10.1039/c6sc02644c. Epub 2016 Jul 01.

We show that a perylene bisimide (PBI)-based gelator forms self-sorted mixtures with a stilbene-based gelator. To form the self-sorted gels, we use a slow pH change induced by the hydrolysis of glucono-δ-lactone (GdL) to gluconic acid. We prove that...

Key bacterial families (Clostridiaceae, Erysipelotrichaceae and Bacteroidaceae) are related to the digestion of protein and energy in dogs.

PeerJ

Bermingham EN, Maclean P, Thomas DG, Cave NJ, Young W.
PMID: 28265505
PeerJ. 2017 Mar 02;5:e3019. doi: 10.7717/peerj.3019. eCollection 2017.

BACKGROUND: Much of the recent research in companion animal nutrition has focussed on understanding the role of diet on faecal microbiota composition. To date, diet-induced changes in faecal microbiota observed in humans and rodents have been extrapolated to pets...

Aligning self-assembled gelators by drying under shear.

Chemical communications (Cambridge, England)

Draper ER, Mykhaylyk OO, Adams DJ.
PMID: 27146964
Chem Commun (Camb). 2016 May 25;52(42):6934-7. doi: 10.1039/c6cc02824a. Epub 2016 May 05.

We show how drying under shear can be used to prepare aligned fibres and worm-like micelles from low molecular weight gelators. Shearing followed by drying leads to the dealignment before the water can be removed; continuous shear whilst drying...

Optimising low molecular weight hydrogels for automated 3D printing.

Soft matter

Nolan MC, Fuentes Caparrós AM, Dietrich B, Barrow M, Cross ER, Bleuel M, King SM, Adams DJ.
PMID: 29083003
Soft Matter. 2017 Nov 22;13(45):8426-8432. doi: 10.1039/c7sm01694h.

Hydrogels prepared from low molecular weight gelators (LMWGs) are formed as a result of hierarchical intermolecular interactions between gelators to form fibres, and then further interactions between the self-assembled fibres via physical entanglements, as well as potential branching points....

Controlling the crystallization of porous organic cages: molecular analogs of isoreticular frameworks using shape-specific directing solvents.

Journal of the American Chemical Society

Hasell T, Culshaw JL, Chong SY, Schmidtmann M, Little MA, Jelfs KE, Pyzer-Knapp EO, Shepherd H, Adams DJ, Day GM, Cooper AI.
PMID: 24410310
J Am Chem Soc. 2014 Jan 29;136(4):1438-48. doi: 10.1021/ja409594s. Epub 2014 Jan 21.

Small structural changes in organic molecules can have a large influence on solid-state crystal packing, and this often thwarts attempts to produce isostructural series of crystalline solids. For metal-organic frameworks and covalent organic frameworks, this has been addressed by...

Swellable, water- and acid-tolerant polymer sponges for chemoselective carbon dioxide capture.

Journal of the American Chemical Society

Woodward RT, Stevens LA, Dawson R, Vijayaraghavan M, Hasell T, Silverwood IP, Ewing AV, Ratvijitvech T, Exley JD, Chong SY, Blanc F, Adams DJ, Kazarian SG, Snape CE, Drage TC, Cooper AI.
PMID: 24874971
J Am Chem Soc. 2014 Jun 25;136(25):9028-35. doi: 10.1021/ja5031968. Epub 2014 Jun 11.

To impact carbon emissions, new materials for carbon capture must be inexpensive, robust, and able to adsorb CO2 specifically from a mixture of other gases. In particular, materials must be tolerant to the water vapor and to the acidic...

On the syneresis of an OPV functionalised dipeptide hydrogel.

Soft matter

Castilla AM, Wallace M, Mears LL, Draper ER, Doutch J, Rogers S, Adams DJ.
PMID: 27714311
Soft Matter. 2016 Sep 20;12(37):7848-7854. doi: 10.1039/c6sm01194b.

We describe a new dipeptide hydrogel based on an oligophenylene vinylene core. After gelation, the initial network evolves, expelling solvent and resulting in syneresis. We describe this process and the effects in the bulk properties of the material.

A simple heat/cool cycle can be used to significantly affect the properties of a solution of a low-molecular-weight gelator at high pH. The viscosity and extensional viscosity are increased markedly, leading to materials with very different properties than when...
