Materials Inorganics: ceramics; layered materials; microporous solids and zeolites; silicates and synthetic minerals; biogenic minerals. Organics: or anometallic ecursors for thin films/ceramics;novel molecuL solids anfiynthetic polymers with materials applications; rlrmer composites; biopol mers; biocompatible and biodegra ab e polymers; liquid cryst& (both lyotropic and thermotropic); Langmuir-Blodgett films.Properties and Applications Electrical properties: semi-, metallic and superconductivity; ionic conductivity; mixed ionic/electronic conductivity; ferro-, pyro- and piezoelectricity; electroceramics; dielectrics. Optical properties: luminescence, phosphorescence, laser ac- tion; non-linear optical effects; photoconductivity; photo- and electro-chromism, resists, glasses, amorphous semiconductors; optical modulation and switching. Magnetic properties: ferro-, ferri- and antiferro-magnetism, spin glass behaviour, organic magnetism, magnetic bubbles and in- formation storage. Chemical properties: ion exchange, molecular separation, cata- lytic action, sensor action, topochemical control of reactions. Structural properties: structural ceramics, refractories; hard ma- terials; protective coatings; composites, adhesives; prosthetic applications.Thermodynamic properties arui phase behaviour Articles Full papers contain original scientific work that has not been published previously. However, work that has appeared in print in a short form such as a Materials Chemistry Communication or Chemical Communication is normally acceptable. But note that the Society strongly discourages the fragmentation of a substantial body of work into a number of short publications. Papers should be typewritten in double spacing on one side only of the paper.Four copies of text, illustrations (full colour copies for coloured figsJplates), tables and any other matter should be sent to: The Editor, Journal of Materials Chemistry, The Royal So-ciety of Chemistry, Thomas Graham House, Science Park, Milton Road, Cambridge CB4 4WF, UK. Feature Articles Feature Articles are published by invitation of the Materials Chemistry Editorial Board. Materials Chemistry Communications Materials Chemistry Communications contain novel scientific work in short form and of such importance that rapid publica- tion is desirable. Authors should briefly indicate in a covering letter the reasons why they feel that publication of their work as a Communication is justified. The total length is rigorously re- stricted to two printed A4 pages.The manuscript will be re-turned for reduction if this length is exceeded. For a Communication consisting of text and ten references, with no figures, equations or tables, this corresponds to approximately1600 words plus an abstract of up to 40 words. Submission of a Materials Chemistry Communication can be made either to The Editor, Journal of Materi.uk Chemistry, The Royal Society of Chemistry, Thomas Graham House, Science Park, Milton Road, Cambridge CB4 4WF, UK,or via a mem- ber of the International Advisory Editorial Board. In the latter case, the top copy of the manuscript including any figures etc.,together with the name of the person to whom the Communi- cation is being submitted, should be sent simultaneously to The Editor at the Cambridge address. Authors may wish to contact the Board member to ensure that he is available to arrange review of the manuscript within reasonable time.Administrat ion Receipt of a paper will be acknowledged, and the paper will be given a reference number which authors are asked to quote on all their subsequent correspondence. If no such acknow- ledgement has been received after a reasonable period of time authors should check with the Editorial Office as to whether the paper or the acknowledgement has gone astray. Editorial Policy. Every paper (except Communications) will be submitted to at least two referees, by whose advice the Ma- terials Editorial Board will be guided as to its acceptability. Full details are given in Refereeing Procedure and Policy, J.Muter. Chem., 1991, Issue 1. Papers that are accepted must not be published elsewhere except by permission of the Royal Society of Chemistry. Submission of a manuscript will be re-garded as an undertaking that the same material is not being considered for publication by another journal. Conditions gov- erning acceptance are available from the Editorial Office. Copyright.The whole of the literary matter (including tables, figures, diagrams and photographs) in Journal of Materials Chemisny is subject to copyright and may not be repro-duced without permission from The Royal Society of Chemistry and such other owner of the copyright as may be indicated. Reprints. Fifty reprints of each paper are supplied free of charge on request.Additional reprints can be purchased if or-dered at the time of publication. Details are sent to authors with the proofs. Notes on the Preparation of Papers 1 Manuscripts must be typed in double-line spacing, single sided on A4 paper, with margins at top, bottom and left-hand side of at least 4 cm. 2 The fiist page should be set out as follows: (i) Name and address of the author to whom proofs and correspondence should be sent. (ii) Title of the paper, with capitals for the first letter of each noun and adjective only. (iii) Authors’ names, including one forename for each author. (iv) The address where the work was carried out; if this is different from the current address of any author wishing to deal with correspondence a footnote indicating the present address of this author should be included.(v) Abstract, preceded and followed by a horizontal line, and typed in double-line spacing. (vi) Keywords, or key phrases, (maximum of five) indicat- ing the topics of importance in the work described. 3 Suitable headings and sub-headings should be used in the main text as appropriate (except for Communications in which no headings are used). References should be numbered serially in the text by means of superscript arabic numerals. 4 Bibliographic references (not footnotes) should follow the main text and should have the following format: 1 R. M. Bmer and R. J. B. Craven, J. Chem. Soc., Fa-raday Trans. 1, 1987,83,779. 2 R.M. Baner and R. J. B. Craven, in New Develop-ments in Zeolite Science and Technology, ed. Y.Mu-rakame, A. Iijima and J.W. Ward, Kodansha, Tokyo, 1986, p. 521. Journal titles should be abbreviated according to the Chemical Abstracts Service Source Index (CASSI). vii 5 Tables should be typed on separate sheets at the end of the manuscript. 6 Diagrams should be accompanied by a separately typed set of captions. Extensive identifying lettering should be placed in the captions rather than on the figures. Original artwork should be supplied wherever possible. Colour photographs will be ac-cepted subject to approval by the referees. 7 Bulk information (such as primary kinetic data, computer programs and output, etc) which accompanies papers published in Journal of Materials Chemistry may be &posited, free of charge, with the Society’s Supplementary Publications Scheme, either at the request of the author and with the approval of the referees or on the recommendation of the referees with the ap- proval of the author.Details are available from the Editorial Office. Nomenclature Current IUPAC nomenclature and symbolism should be used. Crystallographic Papers Crystallographic work will be assessed mainly for its relevance to materials. Papers reporting only the results of crystal struc- ture determination may be accepted for publication provided they are for materials with potentially interesting properties, Crystallographic work that forms parts of a wider study, in- cluding synthesis or property measurements, should not nor- mally by submitted for publication separately from the results of that study.Papers containing new crystal data should make explicit mention of this in the title. The description of a crystallographic structure determina- tion should be as brief as possible; in particular, it is not the policy of the journal to publish lengthy data tables. For publication as part of their papers authors should include: a table of final fractional atomic coordinates (but without mi- sotropic temperature factors); a table of key bond lengths and angles; and a conventional line drawing of the structure. Addi- tional data (any calculated coordinates; full list of bond lengths and angles; thermal parameters; structure factors; least-square planes) should be submitted as supplementary material for use by the referees.Apart tiom the structure factors this material will be deposited at the Cambridge Crystallographic Data Centre, University Chemical Laboratories, Lensfield Road, Attention is drawn to the following publications in which the rules themselves and guidance on their use are given: Nomenclature of Inorganic Chemistry, Blackwell Scien- tific Publications, Oxford, 1990. Nomenclature of Organic Chemistry, Sections A, B, C, D, E, F, andH, Pergamon Press, Oxford, 1979 edn. Biochemical Nomenclature and Related Documents, The Biochemical Society, London, 1978. Compendium of Chemical Terminology: IUPAC Recom- mendations, Blackwell Scientific Publications, Oxford, 1987.Units and Symbols The recommendations of IUPAC should be followed. Their basis is the ‘Systkme Intemationale d’Unit& (SI). A detailed treatment is given in the so-called Green Book: Quantities, Units and Symbols in Physical Chemistry, Blackwell Scientific Publications, Oxford, 1988 edn. Cambridge CB2 1EW (for molecules with ‘organic, carbon) or the Institut fiir Anorganische Chemie, Universita, Gerhard- Domagk-Str. 1, D-5300BOM (otherwise). Any request to Cam-bridge or BOM for deposited material should be accompaniedby the full literature citation for the paper concerned. Full &-tails regarding presentation of crystallographic work can be found in J. Chem.Soc., Dalton Trans., 1991, Issue 1 or can be obtained from the Editorial Office.Powder Data Power X-ray diffraction data may be published, preferably in tabular form, but should be restricted to studies of new materi- als; also, for cases where the materials are new but have simi- lar powder data to other, well characterized, materials, such data will not usually be included in the journal. However, for the purposes of refereeing, a full data set in tabular form shoud be submitted, as supplementary material, simultaneously with the paper; this material will subsequently be deposited with the Society’s Supplementary Publications Scheme (details available from the Editorial Office). Diagrams showing diffraction patterns of reaction products will not normally be included in the journal, unless they have some distinct feature of particular relevance to the discussion. ...Vlll Journal of MaterialsChemistry Materials Chemistry Editorial Board Anthony R.
