From William Morris to today: the textiles of the Cotswolds
William Morris (1834-1896) described the Cotswolds as ‘a heaven on earth’. This exhibition at the Gordon Russell Design Museum, explores the abundant inspiration the area has provided for Morris and many other textile designers.
As well as drawing on the Museum’s own collection, in particular the work of Marian Pepler (1904-1997), the show will also include loans from other Museums and private collectors, including an early piece by William Morris. The exhibition will feature the work of other 20th Century textile designers including: Ethel Mariet (1872-1952) who worked at Broad Campden, Phyllis Barron (1890-1964) and Dorothy Larcher (1884-1952) who lived and worked at Painswick, and Tibor Reich (1916-1996) who produced all-wool coverings for Gordon Russell Ltd.
To complement these early interpretations of the Cotswolds influence, the exhibition will display work by garment designer/maker Dorothy Reglar and current Gloucestershire Guild members Tim Parry-Williams, Liz Lippiatt, Sarah Beadsmore and the team of Rebecca Aird and Peter Thwaites at Rapture & Wrigh

Morris/Trasov Archive
The author describes the archive assembled by Trasov and Morris between 1968 and 1990, considered simultaneously as a work of art and a research tool and acknowledged as the largest collection of mail art and correspondance in Canada
Synthesis and structural characterization of a single-crystal to single-crystal transformable coordination polymer
A single-crystal to single-crystal transformable coordination polymer compound was hydrothermally synthesized. The structural rearrangement is induced by selecting a ligand that contains both strong and weaker coordinating groups. Both hydrated and dehydrated structures were determined by single crystal X-ray analysis.Peer reviewe
Unified mathematical treatment of complex cascaded bipartite networks: The case of collections of journal papers
In this study, a mathematical treatment is proposed for analysis of entities and relations among entities in
complex networks consisting of cascaded bipartite networks. This treatment is applied to the case of
collections of journal papers. In this case, entities are distinguishable objects and concepts, such as papers,
references, paper authors, reference authors, paper journals, reference journals, institutions, terms, and term
definitions. Relations are associations between entity-types such as papers and the references they cite, or
paper authors and the papers they write. An entity-relationship model is introduced that explicitly shows
direct links between entity-types and possible useful indirect relations. From this a matrix formulation and
generalized matrix arithmetic are introduced that allow easy expression of relations between entities and
calculation of weights of indirect links and co-occurrence links. Occurrence matrices, equivalence
matrices, membership matrices and co-occurrence matrices are described. A dynamic model of growth
describes recursive relations in occurrence and co-occurrence matrices as papers are added to the paper
collection. Graph theoretic matrices are introduced to allow information flow studies of networks of papers
linked by their citations. Similarity calculations and similarity fusion are explained. Derivation of feature
vectors for pattern recognition techniques is presented. The relation of the proposed mathematical
treatment to seriation, clustering, multidimensional scaling, and visualization techniques is discussed. It is
shown that most existing bibliometric analysis techniques for dealing with collections of journal papers are
easily expressed in terms of the proposed mathematical treatment: co-citation analysis, bibliographic
coupling analysis, author co-citation analysis, journal co-citation analysis, Braam-Moed-vanRaan (BMV)
co-citation/co-word analysis, latent semantic analysis, hubs and authorities, and multidimensional scaling.
This report discusses an extensive software toolkit that was developed for this research for analyzing and
visualizing entities and links in a collection of journal papers. Additionally, an extensive case study is
presented, analyzing and visualizing 60 years of anthrax research through a collection of journal papers.
When dealing with complex networks that consist of cascaded bipartite networks, the treatment presented
here provides a general mathematical framework for all aspects of analysis of static network structure and
network dynamic growth. As such, it provides a basic paradigm for thinking about and modeling such
networks: computing direct and indirect links, expressing and analyzing statistical distributions of network
characteristics, describing network growth, deriving feature vectors, clustering, and visualizing network
structure and growth
Coordination polymers of 5-alkoxy isophthalic acids
The topology of coordination polymers containing 5-alkoxy isophthalic acids and first row transition metals was found to be dependent on the combination of solvent system used and length of the alkyl chain. Four different framework types were identified: Phase A, M6(ROip)5(OH)2(H2O)4·xH2O (M = Co and R = Et, Pr, or nBu, or M = Zn and R = Et); Phase B, M2(ROip)2(H2O) (M = Co or Zn and R = Et, Pr, nBu, or iBu, or M = Mn and R = nBu or iBu); Phase C, Zn3(EtOip)2(OH)2; and Phase D, Zn2(EtOip)2(H2O)3. Preliminary screening of the NO storage and release capabilities of the Co-containing materials is also reported.</p
Novel flexible MOFs, their application and in situ scXRD studies of gas loaded MOFs
Metal-organic frameworks (MOFs) are an exciting class of porous materials with a large variety of potential applications. Finding and analysing new MOF systems is important for the development of new technologies, including in medicine and pollution capture. Furthermore, using high quality in situ single crystal X-ray diffraction (scXRD) is necessary to understand how MOFs capture, store and release gas molecules.
Presented here are novel frameworks based on 2,3-dihydroxyterephthalic acid and the M(II) metal ions Mg, Ni, Co, Ca and Cu. So far nine different phases have been solved structurally with six new to this body of work. SIMOF-3 (St Andrews Isoreticular MOF) can be formed from Mg, Ni and Co. It contains a disordered pillar linker that may be flexible. The Ca phase SIMOF-4 is denser with a phase change to an even denser phase on solvent removal. However, this material did show utility as an anode in a sodium battery. Cu produced two distinct phases both showing breathing behaviour. The more stable phase has shown excellent capacity for the storage and release of the drug molecules Ibuprofen, Flutamide and caffeine as well as the adsorbtion of the medicinal gas nitric oxide (NO).
In addition, in situ scXRD studies have been performed on Ni-CPO-27 and Co-4,6-dhip to investigate the binding of the polar gases NO, CO and SO₂. This has uncovered the relative binding strengths of these gases, their competitive interactions with water and the presence of physisorbed binding sites.
Finally, a series of mixed metal Ni/Cu CPO-27 analogues were synthesised that could release preadsorbed NO on addition of moisture as well as catalytically generate NO from S-nitrosoglutathione. The framework and its stability in biological media were investigated with Ni₀.₁Cu₀.₉-CPO-27 showing excellent all round properties suitable for inclusion into future medical devices

Coordination polymers of ZnII and 5-methoxy isophthalate
This work was funded by the British Heart Foundation (NH/11/8/29253) and the EPSRC (EP/K005499/1).Solvothermal reaction of Zn(OAc)2 and 5-methoxy isophthalic acid (H2MeOip) in aqueous alcohols ROH (R = H, Me, Et, or iPr) affords four different novel coordination polymers. Zn2(HMeOip)(MeOip)(OAc) (1) forms as a 1D 'ribbon of rings' polymer. Zn6(MeOip)4.5(HMeOip)(OH)2(H2O)2·5.5H2O (2) crystallises as a complex 3D framework. Zn(MeOip)(H2O)2 H2O (3) is a 1D coordination polymer that contains almost planar strips of Zn(MeOip). compound 4, Zn5(MeOip)4(OH)2(H2O)4·H2O, obtained from aqueous iPrOH, crystallises as a 2D polymer containing two crystallographically distinct Zn5(OH)2 clusters. Preliminary nitric oxide release experiments have been conducted.Peer reviewe
