A great deal of progress has recently been made in the field of ordered porous materials with uniform channel dimensions that can be adjusted over a wide range of length scales. The present paper describes the state of the art and the evolution from highly ordered mesoporous silica, aluminosilicate and pure carbon materials to our very recent success in hierarchically structured meso-macroporous carbon materials, single and binary oxides and aluminosilicates. By means of selected examples, we want to shed some light on the current strategies for the conception of these sophisticated materials. The great potential applications of these new nanomaterials emerge while their real utilisation in some expected and traditional industrial processes such as catalysis, separation, electrode materials for fuel cells and biomaterials still faces some important challenges, for example, the high price, the pelletisation and the stability (thermal, hydrothermal and water resistance). Some new perspectives, which can open the concrete applications of these materials in nanotechnology, biotechnology, information technology and medical purposes, will be prospected.

Single and multiwalled carbon nanotubes have attracted significant interest due to their one-dimensional structure and unique electrical and mechanical properties. Among the wide variety of their potential applications most importantly they offer potential to serve as building blocks for future electronic device architectures [1, 2, 3, 4, 5, 6]. Carbon nanotubes may serve as active or passive electronic elements; and as passive elements they may serve as interconnects both on short and long ranges [7, 8]. The most essential prerequisite for realizing CNT architectures is to be able to grow nanotubes at controlled sites, in predetermined orientations and to form interconnections. Significant progresses in growing aligned carbon nanotube films have been made recently with a combined approach of the floating catalyst method using pre-patterned templates and chemical vapor deposition (CVD) [9, 10, 11, 12]. Recently we summarized our work on growing architectures of carbon nanotubes, which might be integrated into microelectronic circuits [13]. While the predefined growth of the above mentioned large nanotube structures is important and receives a lot of attention characterization of the product also deserves similarly high attention being a key for future applications and giving the real importance and purpose of the growth efforts. In this paper, we report some of our works, which are directed towards electrical tests on CNTs, namely high current carrying capacity; vertically organized multiwalled nanotubes showing the possible usage of highly ordered and well-shaped tubes; and characterization of singlewalled nanotube junctions.

The storage of wheat data in computers began in the mid-eighties in Martonvásár, and was accompanied by the development of the first simple programs to assist the data management of routine breeding tasks. The great expansion of breeding materials and the demand for new applications have led to an enormous increase in the number of data and have made data processing increasingly more complicated. Data storage facilities and computer programs reflecting an outdated technological level were unable to keep pace with developments. Data storage and applications had to be redesigned on new lines to create a completely new information system amalgamating know-how from breeding and informatics.The paper introduces an extremely important part of this system: pedigree records, which contain the designations of all the genotypes included in traditional field breeding programmes and in the gene bank, together with crossing data, phenotypes and genomic data.An up-to-date, consistent pedigree register is one of the key components in the breeding information system, without which the maintenance and alteration of the names of plant species (wheat, barley, oats, etc.) and linking them to experiments and experimental quality data would be an extremely complex, time-consuming task. It would be even more difficult to keep track of all the genotypes and the increasingly large numbers of related lines from year to year.In addition to describing the rationale behind the system, details will be given on the tools and conditions required for the establishment of the pedigree records, and the internal and external sources available. Finally, some practical examples will be given of how the Martonvásár wheat breeding information system has been applied.

Abstract  

In SCTA application to high polymers, we do not find remarkable and illustrative results such as found in multiple step dehydration processes of low molecular mass substances. However, some characteristic results were obtained in the application to high polymers, and three examples are described in this report.

Abstract  

Nuclear data are numerical quantities that describe nuclear properties and nuclear interactions. Arranged into data libraries, they ultimately constitute the very basis of all nuclear applications. Nuclear data have to be measured, compiled, evaluated and validated so that users get the best and up-to-date information in an unrestricted manner. The paper provides an insight into this activity, describes the process from measurements to nuclear data services, illustrates key applications, and discusses future trends and developments.
