‘Hard-Soft’ Synthesis of SrCrO3-δ Superstructure Phases

We demonstrate ‘hard-soft’ oxide synthesis through low temperature reduction (“soft”) of the high-pressure perovskite SrCrO3 (“hard”). This yields two new SrCrO3-δ phases (δ = 0.2 and 0.25) with unusual superstructures and properties.

The Electronic States of Pyridine-N-Oxide Studied by VUV Photoabsorption and Ab Initio Configuration Interaction Computations

UV+VUV spectrum for Pyridine-N-oxide. Calculated valence states are superimposed and 1A2 states have been  given an arbitrary oscillator strength f(r) = 1 x 10-5 in order to indicate their positions.

Model’s Reputation Restored

The structure of a mineral has been validated, ending the controversy about its potential usefulness as a model of an unusual magnetic lattice. This model might provide insight into superconductivity.

How Much Do Van Der Waals Dispersion Forces Contribute to Molecular Recognition in Solution?

Attractive van der Waals dispersion forces have been implicated in mechanisms as diverse as gecko adhesion and anaesthesia. It has been found that dispersion forces between alkyl chains are an order of magnitude weaker in solution than in the gas phase.

Amino-Alcohol Cyclization: Selective Synthesis of Lactams and Cyclic Amines from Amino-Alcohols

The cyclization of various amino-alcohols by homogeneous ruthenium catalysts can be steered to either the cyclic amine or to the lactam in high selectivity. This selective and atom-efficient transformation provides access to a range of N-heterocyclic compounds.

Detecting Low-Level Flexibility Using Residual Dipolar Couplings: A Study of the Conformation of Cellobiose

The solution state NMR analysis of a large number of residual dipolar couplings showed low-level flexibility in cellobiose, the disaccharide repeating unit of cellulose. The sources of this flexibility are attributed to the Ψ rather than the Φ dihedral angle.

Deep Ultraviolet and Visible Crystalloluminescence of Sodium Chloride

Crystalloluminescence: luminescence emitted during crystallisation of sodium chloride. Experiments show that the emission is due to trace amounts of univalent metal cation defects trapped during the nucleation, and not triboluminescence. Each pin-prick of light comes from an individual...

Tacticity-Induced Changes in the Micellization and Degradation Properties of Poly(Lactic Acid)-Block-Poly(Ethylene Glycol) Copolymers

Control of tacticity in biodegradable polymers can alter the physical properties of the resultant materials. In this paper, we examine amphiphilic block copolymers made of poly(ethylene glycol) and poly(lactic acid) segments.

Mission Statement

EaStCHEM's key aim is for excellence in both core and interdisciplinary research, through the generation of a physical and intellectual environment that rivals the best in the world. EaStCHEM, the joint chemistry research School of the Universities of Edinburgh and St Andrews, was conceived in 2003 with the aim of harnessing the complementary capabilities and capitalising on the synergies of Scotland's two leading Chemistry Departments.
