Showing papers in "Materials Today in 2003"

TL;DR: In this paper, the authors present a review of hydrogen storage on materials with high specific surface area, hydrogen intercalation in metals and complex hydrides, and storage of hydrogen based on metals and water.

TL;DR: In this article, the authors review the materials currently under development for application in such devices with particular reference to some of the newly discovered oxide ion conductors, which offer the potential of enormous commercial and ecological benefits provided suitable high performance materials can be developed.

TL;DR: The bottom-up, self-assembly process enables accurate control of dimension, location, composition, and other properties as discussed by the authors. But this process does not come without a price; the cost of new fabs is growing extremely fast, at a pace that may limit continued progress, simply because devices and circuits become too expensive to be economically viable.

TL;DR: The hydrogen storage is proving to be one of the most important issues and potentially biggest roadblock for the implementation of a hydrogen economy as discussed by the authors, and of all known hydrogen storage materials, complex hydrides may be the only hope.

TL;DR: In addition, fuel cells have been shown to have high efficiency and low emissions, and are attractive for their modular and distributed nature, and zero noise pollution as discussed by the authors, and they will also play an essential role in any future hydrogen fuel economy.

TL;DR: The first CaP coatings were produced via vapor phase processes, but more recently solution-based and biomimetic methods have emerged as mentioned in this paper, which promise to improve implant biocompatibility and ultimately implant longevity.

TL;DR: In this article, two key elements in molecular self-assembly are chemical complementarity and structural compatibility through weak and non-covalent interactions, and they have been defined the path to understand these principles.

TL;DR: A series of self-cleaning surfaces have been proposed to remove the need for regular washing, scrubbing, and polishing with chemical agents as discussed by the authors. But consumers should refrain from throwing away all their cloths and detergents just yet.

TL;DR: For example, this paper found that students experience difficulties in learning physics because they must fully understand concepts and principles of the physical world that are sometimes impossible to see (as in electromagnetism phenomena) and often difficult to comprehend.

TL;DR: In this article, product personality and character is explored, illustrating the ideas by analyzing a number of products, noting particularly how the choice of material and process has contributed.

TL;DR: In this article, the authors discuss the challenges in scaling up the handmade garments and how best to use the technology, and the question of whether these garments will go in the wash.

TL;DR: For instance, the authors states that man is so made that, whenever anything fires his soul, impossibilities vanish, and this is the case for any task he is asked to solve.

TL;DR: Examples of the basic, as well as practical, knowledge of molecular biology that might be useful to material scientists are focused on, with emphasis on ‘materials building blocks’ and ‘molecular biology tool kits’ that can be employed for new materials design and synthesis.

TL;DR: This review focuses on a versatile approach that combines the formation of solid-supported lipid bilayers by deposition of lipid vesicles with the adsorption of proteins and formation of ordered protein layers via specific interaction with ligands incorporated in the SLBs.

TL;DR: In this article, a pathway from microcharacterization to macroscopic properties of materials is discussed on metal/ceramic composites and an assessment of the properties of these materials is presented.

TL;DR: The description of a quantum dot can be applied to a great variety of structures, some of which are defined by physical characteristics, such as self-assembled dots, and others by the imposition of a self-consistent potential applied through confining gates as discussed by the authors.

TL;DR: In this paper, the authors make predictions that 10 GHz microprocessor clock speeds, compared with the present 2.8 GHz state-of-the-art, should be achieved by 2006.

TL;DR: The theory of defects in silicon has evolved tremendously in the past half century and has become quantitative in many respects as mentioned in this paper, and a review gives an overview of the evolution of theory and a discussion of ongoing developments.

TL;DR: Dip-pen nanolithography (DPN) is generating significant interest as a means of patterning surfaces with submicron-scale designs as discussed by the authors, but it is not without its critics, who question the utility and practicality of paint-pot-style nanofabrication.

TL;DR: Using technology first developed as the atomic force microscope to trace topography down to the scale of individual atoms and molecules can enable data to be stored at densities as high as 1 Tb/in 2 — a density ten times higher than today’s most advanced disk drives.

TL;DR: Atomic force microscopy (AFM) has revolutionized surface characterization by allowing the researcher to examine the molecular structure of virtually any sample under virtually any environmental condition The AFM is used to produce information about surface topography, elasticity, friction, adhesion, charge density, magnetic structure, or even long-range effects Compared to traditional spectroscopic surface analytical tools, the AFM suffers from a remarkably low data content Chemical modification of the tip incorporates chemical information within the measurements as discussed by the authors.
