Abstract Thermogravimetry (TG) and differential thermal analysis (DTA) are traditional, but still useful, experimental techniques for obtaining information in the realms of materials and solid state chemistry. This paper presents two case studies (many more could be cited) to illustrate the strengths (and limitations) of these techniques: (1) Iron doping of clinoptilolite (the most common zeolite): the typical parameters of both components appear clearly in the TG and DTA curves. The decrease of the Tmax value of the structurally-typical DTA effect of FeOOH by approximately 100°C is attributed to the weakening of chemical bonds in FeOOH due to the incorporation of the doping component into the structure of this zeolite. (2) Macrodefect-free (MDF) materials: the results of both TG and DTA unambiguously locate the typical temperature range of the decomposition of the P{4}–O–Al/Fe{6} cross-links within the interval of 200–300°C. The presence of cross-links is shown by the DTA data while the TG data can be used to measure the degree of cross-linking, which is valuable information when studying both raw mixes and the final materials for a variety of MDF materials.

This review presents the main patterns of synthesis for theranostics platforms. We examine various approaches to the interpretation of theranostics, statistics of publications drawn from the PubMed database, and the solid-state and medicinal chemistry methods used for the formation of nanotheranostic objects. We highlight and analyze chemical methods for the modification of nanoparticles, synthesis of spacers with functional end-groups, and the immobilization of medicinal substances and fluorophores. An overview of the modern solutions applied in various fields of medicine is provided, along with an outline of specific examples and an analysis of modern trends and development areas of theranostics as a part of personalized medicine.

The IUPAC-sponsored Conference on Solid State Chemistry (SSC 2008), the eighth conference in the series since 1986, was held in Bratislava, Slovakia 6-11 July 2008. The first Solid State Chemistry Conference held in Karlovy Vary, Czech Republic, was a nucleus of this series, which has grown over the years and resulted in well-established meetings organized biannually, either in Czech or Slovak Republic. The reader can find examples of feedback on this series in the back issues of Pure and Applied Chemistry (PAC), which comprise the papers and opinions of invited speakers of the fifth conference in this series, also IUPAC-sponsored "Solid State Chemistry 2002".SSC 2008 focused on the branches of solid-state and materials chemistry. The event attracted not only scientists but also the producers of new materials and technologies. Over 200 participants from 29 countries representing Europe, Asia, the Americas, and Africa attended the conference and presented 18 invited talks, 73 lectures, and 146 posters. The scientific program comprised the following seven sessions:- Synthesis and Characterization of Materials- Crystal, Electronic, and Magnetic Structure- Electrochemistry and Molten Salts- Chemistry of Glasses- Novel Inorganic Materials and Nanomaterials- Layered Compounds, Clathrates, and Intercalates- Deposited Films and Surface ChemistryThe invited lectures together with the rigorous choice of further influential lectures, published in this special issue of PAC, cover each topic of the conference and have been an excellent base for the discussions and represent hints for future development in the field. In addition, the lecturers were given the option of submitting manuscripts of research articles, communications, or reviews based upon their lectures or posters to Chemical Papers and Central European Journal of Chemistry (CEJC). The papers accepted by CEJC have already appeared in Vol. 7, Number 2, June 2009. The conference was organized by the Institute of Inorganic Chemistry of the Slovak Academy of Sciences, the Faculty of Chemical and Food Technology of Slovak University of Technology, and the Faculty of Natural Sciences of Comenius University. The conference continues to provide a friendly atmosphere for the exchange of new results and ideas among groups active in different areas of solidstate and materials chemistry.The 9th Conference on Solid State Chemistry will be held in mid-September 2010 in Prague, Czech Republic. A Web page containing an online "expression of interest" form is already active: www.ssc2010.cz. We look forward to meeting the solid-state and materials chemistry community again at this conference.Milan DrábikSSC 2008 Conference Editor
