Pumice is a volcanic rock that consists of a highly vesicular rough textured volcanic glass. It is very porous and shows a high absorption - it can contain a lot of water. Thanks to its low volume density, it is sometimes used as a light natural aggregate, especially for some small elements such as chimney blocks. The paper is focused on the development of concretes and mortars for these purposes. The optimum content of pumice was specified from the point of view of mechanical properties. Special attention was paid to absorbed water - it can be a source of self-curing of concrete.

Market Volume

Nanocellulose provides a new materials platform for the sustainable production of high-performance nano-enabled products in an array of applications. In this paper, potential applications for cellulose nanomaterials are identified as the first step toward estimating market volume. The overall study, presented in two parts, estimates market volume on the basis of estimated tonnage of cellulose nanomaterials rather than the dollar value of production or profits from production. In this paper, we first identified potential uses from literature, presentations, and patent reviews, and then categorized these under the broad headings of high-volume, low-volume, and emerging/novel applications. For each application, the rationale for using nanocellulose is explained. The companion paper, Part 2, explains the assumptions and calculation of application-specific market estimates. High- and low-volume consumption applications of cellulose nanomaterials were identified from published data as well as expert input. We categorized potential market sizes as high or low by considering applications where cellulose nanomaterials would replace existing materials and be used at a published or estimated rate for some fraction of an entire existing market. Novel applications for cellulose nanomaterials that are presently considered niche markets are also identified, but volumes were not estimated because of a lack of published supporting data. Annual U.S. market potential for identified applications of nanocellulose is estimated as 6.4 million metric tons, with a global market potential of 35 million metric tons. The greatest volume potential for use of cellulose nanomaterials is currently in paper and packaging applications. Other potentially high-volume uses are in the automotive, construction, personal care, and textile sectors.

Novel Applications

Nanocellulose has enormous potential to provide an important materials platform in numerous product sectors. This study builds on previous work by the same authors in which likely high-volume, low-volume, and novel applications for cellulosic nanomaterials were identified. In particular, this study creates a transparent methodology and estimates the potential annual tonnage requirements for nanocellulose in the previously identified applications in the United States (U.S.). High, average, and low market penetration estimates are provided for each application. Published data sources of materials use in the various applications provide the basis for estimating nanocellulose market size. Annual U.S. market potential for high-volume applications of nanocellulose is estimated at 6 million metric tons, based on current markets and middle market penetration estimates. The largest uses for nanocellulose are projected to be in packaging (2.0 million metric tons), paper (1.5 million metric tons), and plastic film applications (0.7 million metric tons). Cement has a potential nanocellulose market size of over 4 million metric tons on a global basis, but the U.S. market share estimated for cement is 21,000 metric tons, assuming market penetration is initially limited to the ultra-high performance concrete market. Total annual consumption of nanocellulose for low-volume applications is less than 10% of the high-volume applications. Estimates for nanocellulose use in emerging novel applications were not made because these applications generally have yet to come to market. The study found that the majority of the near-term market potential for nanocellulose appears to be in its fibrillar versus crystalline form. Market size estimates exceed three prior estimates for nanocellulose applications, but the methodologies for those studies are not transparent.

Historically, uranium enriched to >90% 235U has been used for many peaceful applications requiring high fission densities such as driver fuels for research reactors. However, the use of high-enriched uranium or HEU (all enrichments >20% 235U are considered HEU) for civil applications, is considered a proliferation concern. Since the 1970's, efforts are being devoted to the conversion of research reactors operating on HEU to alternative fuels using uranium with enrichment below 20% or LEU. These efforts imply the development of high-density LEU fuels to replace the low volume-density (mostly) UAlx based HEU fuels. The paper updates the present status of these developments focusing on the UMo dispersion fuel. It aims to provide an overview of the knowledge generated and the lessons learned in roughly 15 years of UMo dispersion fuel R&D in Europe through irradiation experiments and post-irradiation examinations (PIE).

Abstract Recently, elastomer - nanocomposites reinforced with low volume fraction of nanofillers have attracted great interest due to their fascinating properties. The incorporation of nanofillers such as layered silicate clays, carbon nanotubes, nanofibers, calcium carbonate, metal oxides or silica nanoparticles into elastomers improves significantly their mechanical, thermal, dynamic mechanical, barrier properties, flame retardancy, etc. The properties of nanocomposites depend greatly on the chemistry of polymer matrices, nature of nanofillers, and the method in which they are prepared. The uniform dispersion of nanofillers in elastomer matrices is a general prerequisite for achieving desired mechanical and physical characteristics. In this review article, current developments in the field of elastomer nanocomposites reinforced with layered silicates, silica, carbon nanotubes, nanofibers and various other nanoparticles have been addressed. Attention has been paid to the structure and properties of such high-performance nanocomposites, along with the theories and models existing in this field.
