Physical review letters

Tan JC, Civalleri B, Lin CC, Valenzano L, Galvelis R, Chen PF, Bennett TD, Mellot-Draznieks C, Zicovich-Wilson CM, Cheetham AK.
PMID: 22463647
Phys Rev Lett. 2012 Mar 02;108(9):095502. doi: 10.1103/PhysRevLett.108.095502. Epub 2012 Feb 29.

Using Brillouin scattering, we measured the single-crystal elastic constants (C(ij)'s) of a prototypical metal-organic framework (MOF): zeolitic imidazolate framework (ZIF)-8 [Zn(2-methylimidazolate)(2)], which adopts a zeolitic sodalite topology and exhibits large porosity. Its C(ij)'s under ambient conditions are (in GPa)...

Does the presence of robotic surgery affect demographics in patients choosing to undergo radical prostatectomy? A multi-center contemporary analysis.

We report on differences in patient demographics in those men choosing to undergo radical prostatectomy in a UK center where there is no influence of robotic surgery and in those choosing radical prostatectomy in a US center where there...

Synthesis and Self-Assembly of a Mikto-Arm Star Dual Drug Amphiphile Containing both Paclitaxel and Camptothecin.

Journal of materials chemistry. B

Self-assembly of anticancer therapeutics into discrete nanostructures provides an innovative way to develop a self-delivering nanomedicine with a high, quantitative drug loading. We report here the synthesis and assembly of a mikto-arm star dual drug amphiphile (DA) containing both...

Role of hydrogen-bonding and its interplay with octahedral tilting in CH3NH3PbI3.

Chemical communications (Cambridge, England)

Lee JH, Bristowe NC, Bristowe PD, Cheetham AK.
PMID: 25766075
Chem Commun (Camb). 2015 Apr 14;51(29):6434-7. doi: 10.1039/c5cc00979k.

First principles calculations on the hybrid perovskite CH3NH3PbI3 predict strong hydrogen-bonding which influences the structure and dynamics of the methylammonium cation and reveal its interaction with the tilting of the PbI6 octahedra. The calculated atomic coordinates are in excellent...

Oriented Two-Dimensional Porous Organic Cage Crystals.

Angew Chem Int Ed Engl. 2017 Aug 01;56(32):9391-9395. doi: 10.1002/anie.201704579. Epub 2017 Jul 06.

The formation of two-dimensional (2D) oriented porous organic cage crystals (consisting of imine-based tetrahedral molecules) on various substrates (such as silicon wafers and glass) by solution-processing is reported. Insight into the crystallinity, preferred orientation, and cage crystal growth was...

QUANTITATIVE GENETICS OF BRYOZOAN PHENOTYPIC EVOLUTION. III. PHENOTYPIC PLASTICITY AND THE MAINTENANCE OF GENETIC VARIATION.

Evolution; international journal of organic evolution

Cheetham AH, Jackson JBC, Hayek LC.
PMID: 28565013
Evolution. 1995 Apr;49(2):290-296. doi: 10.1111/j.1558-5646.1995.tb02241.x.

Cheilostome bryozoan species show long-term morphologic stasis, implying stabilizing selection sustained for millions of years, but nevertheless retain significant heritable variation in traits of skeletal morphology. The possible role of within-genotype (within-colony) phenotypic variability in preserving genetic diversity was...

Crystalline solids dominate the field of metal-organic frameworks (MOFs), with access to the liquid and glass states of matter usually prohibited by relatively low temperatures of thermal decomposition. In this work, we give due consideration to framework chemistry and...

In Situ Observation of Successive Crystallizations and Metastable Intermediates in the Formation of Metal-Organic Frameworks.

Angewandte Chemie (International ed. in English)

Understanding the driving forces controlling crystallization is essential for the efficient synthesis and design of new materials, particularly metal-organic frameworks (MOFs), where mild solvothermal synthesis often allows access to various phases from the same reagents. Using high-energy in situ...

GaFPO(3)(C(6)H(5)): a new fluorinated gallium phenylphosphonate with a layered network.

Crystals of gallium fluorophenylphosphonate were synthesized hydrothermally at 453 K under autogenous pressure. The solid crystallizes in the monoclinic system and its structure is built up by the connection of zigzag chains of edge-sharing GaO(4)F(2) octahedra to phenylphosphonate groups....
