Available in PDF, EPUB and Kindle. Book excerpt: Aerogels have been in use for over 80 years and have been utilised in a wide variety of applications, in particular, there has been growing use of insulating nanoporous materials in the aerospace industry. Recent awareness of the environmental implications of materials has driven researchers to develop new green materials, with aerogels being developed using biobased constituents, such as polysaccharides and proteins. Recently, biobased components, such as cellulose nanocrystals, have replaced synthetic counterparts in the production of nanoporous materials. Biobased Aerogels is the first book to cover aerogel research from a green perspective, using commentary and analysis from leading researchers working in the field. Aerogels based on polysaccharides and proteins, their preparation and characterisation will be covered in detail, with further discussion highlighting properties such as surface morphology, shape recovery, mechanical properties and adsorption capacity. This insightful and timely publication will provide essential reading for those researchers and industrialists working within the green chemistry field.

Book Synopsis Dust in the Solar System and Other Planetary Systems by : S.F. Green
Download or read book Dust in the Solar System and Other Planetary Systems written by S.F. Green and published by Elsevier. This book was released on 2002-12-10 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the last joint IAU and COSPAR Colloquium in Gainesville in 1995, there have been dramatic changes in the field resulting from in-situ space experiments, Earth orbiting satellites and ground based observations. The brightest comet since the early years of the twentieth century, comet Hale-Bopp, appeared, giving an invaluable opportunity to see in action one great source of interplanetary dust. Similarly, the Leonid meteor shower has been at its most active since 1966, producing spectacular displays of meteors and allowing for an array of observational techniques, not available in 1966 to be used, while theory has also been refined to a level where very accurate predictions of the timing of meteor storms has become possible. Prior to the meeting a total eclipse of the Sun in South West England and North Europe was observed, traditionally a good opportunity to observe the Zodiacal cloud. The knowledge of the Near-Earth Asteroid population has also increased dramatically, with the increased study arising from the heightened awareness of the danger to Earth from such bodies. Extrasolar planets have been discovered since the last meeting and it is recognised that interplanetary dust in other Planetary Systems can now be studied. Since much of the dust observed in such systems is at a distance of order 100 AU from the star, this brings into focus the production of dust in the Edgeworth-Kuiper belt of our own system. Recent years have seen a recognition of the importance of dust originating outside our own system, that is now present in the near-Earth environment. As is always the case when great strides take place observationally, much theoretical work follows, and the same is true in this instance. While data about the planetary medium from Venus to Jupiter was beginning to be available at the meeting in 1995, the data from both Galileo and Ulysses have now been more fully analysed, with a corresponding increase in our knowledge. This book reflects the thematic approach adopted at the meeting, with a flow outwards (from meteors in the atmosphere, through zodiacal dust observation and interplanetary dust, to extra solar planetary systems) and returning (via the Edgeworth-Kuiper belt and comets) to the Earth, with laboratory studies of physical and chemical processes and the study of extra-terrestrial samples.

Book Synopsis Capture of Hypervelocity Particles with Low-Density Aerogel by : National Aeronautics and Space Administration (NASA)
Download or read book Capture of Hypervelocity Particles with Low-Density Aerogel written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-06 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent impact experiments conducted at Johnson Space Center supported a space-exposed flight instrument called the orbital debris collector (ODC) to see whether SiO2 acrogel performed adequately as a collector to capture cosmic dust particles and/or manmade debris, or whether additional development is needed. The first ODC was flown aboard the Mir for 18 months, while the second will be flown aboard a spacecraft (Stardust, to be launched in 1999) that will encounter the comet Wild 2 and return to Earth. Aerogels are highly porous materials that decelerate high-velocity particles without substantial melting or modifications to the particles' components; in other denser materials, these particles would melt or vaporize upon impact. The experimental data in this report must be considered somewhat qualitative because they are characterized by substantial, if not intolerable, scatter, possibly due to experimental difficulties in duplicating given sets of initial impact conditions. Therefore, this report is a chronological guide of the experimenters' attempts, difficulties, progress, and evaluations for future tests.

Book Synopsis Investigation of Hypervelocity Impact Phenomena Using Real-time Concurrent Diagnostics by : Jonathan Michael Mihaly
Download or read book Investigation of Hypervelocity Impact Phenomena Using Real-time Concurrent Diagnostics written by Jonathan Michael Mihaly and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hypervelocity impact of meteoroids and orbital debris poses a serious and growing threat to spacecraft. To study hypervelocity impact phenomena, a comprehensive ensemble of real-time concurrently operated diagnostics has been developed and implemented in the Small Particle Hypervelocity Impact Range (SPHIR) facility. This suite of simultaneously operated instrumentation provides multiple complementary measurements that facilitate the characterization of many impact phenomena in a single experiment. The investigation of hypervelocity impact phenomena described in this work focuses on normal impacts of 1.8 mm nylon 6/6 cylinder projectiles and variable thickness aluminum targets. The SPHIR facility two-stage light-gas gun is capable of routinely launching 5.5 mg nylon impactors to speeds of 5 to 7 km/s. Refinement of legacy SPHIR operation procedures and the investigation of first-stage pressure have improved the velocity performance of the facility, resulting in an increase in average impact velocity of at least 0.57 km/s. Results for the perforation area indicate the considered range of target thicknesses represent multiple regimes describing the non-monotonic scaling of target perforation with decreasing target thickness. The laser side-lighting (LSL) system has been developed to provide ultra-high-speed shadowgraph images of the impact event. This novel optical technique is demonstrated to characterize the propagation velocity and two-dimensional optical density of impact-generated debris clouds. Additionally, a debris capture system is located behind the target during every experiment to provide complementary information regarding the trajectory distribution and penetration depth of individual debris particles. The utilization of a coherent, collimated illumination source in the LSL system facilitates the simultaneous measurement of impact phenomena with near-IR and UV-vis spectrograph systems. Comparison of LSL images to concurrent IR results indicates two distinctly different phenomena. A high-speed, pressure-dependent IR-emitting cloud is observed in experiments to expand at velocities much higher than the debris and ejecta phenomena observed using the LSL system. In double-plate target configurations, this phenomena is observed to interact with the rear-wall several micro-seconds before the subsequent arrival of the debris cloud. Additionally, dimensional analysis presented by Whitham for blast waves is shown to describe the pressure-dependent radial expansion of the observed IR-emitting phenomena. Although this work focuses on a single hypervelocity impact configuration, the diagnostic capabilities and techniques described can be used with a wide variety of impactors, materials, and geometries to investigate any number of engineering and scientific problems.
