Jul 28, 2011. Article. NASA developed ways of creating aerogels that are polymer-reinforced. These aerogels are stronger and can be translucent. Image credit: NASA. Picture preparing a bowl full of a sweet, gelatin dessert. The gelatin powder is mixed with hot water, and then the mixture is cooled in a refrigerator until it sets. It is now a gel.
Engineering of Aerogel-Based Biomaterials for Biomedical Applications
The remarkable properties of a silica aerogel are the result of its nanoscale structure. To visualize that structure, think of holding a pile of small, clear particles in your hand. Imagine that the particles touch one another and slightly stick together, leaving gaps between them that are filled with air.
Biomedical applications of aerogel - ScienceDirect
Super thermal insulation aerogel materials featuring nano-sized cavities, abundant heterogeneous interfaces, and low dielectric properties offer a promising avenue for the development of materials that excel in both passive cooling and high-frequency terahertz (THz) communication efficiency. In this work, pr
Aerogels: Thinner, Lighter, Stronger - NASA
The objective of this research was to develop a high-performance flexible silica aerogel composite for thermal insulation under high-temperature and thermal-force coupling conditions. Based on synthesis of flexible silica aerogels with methyltrimethoxysilane as the precursor, flexible silica aerogel composites were developed by wet-impregnating ceramic fiber felt. Morphology, microstructure ...

How Aerogels Work | HowStuffWorks
Abstract. Aerogels are specialized highly porous and light nanostructures in which nearly 95% air is trapped by the replacement of solvent in the mesh of material. Biomedical application of aerogels have been well explored as antifungal, antibacterial, antiviral, biosensing and imaging agents, tissue engineering, diagnosis, and regenerative ...
What is Aerogel? Theory, Properties and Applications - AZoM.com
A polyethylenimine-modified cellulose nanofibril (PEI-CNF) aerogel is investigated for the recovery and isolation of Pt-group metals (PGMs) from automobile catalyst leachate. The PEI-CNF exhibits excellent Pt, Pd, and Rh adsorption capacities. In particular, the PEI-CNF shows promising Rh uptake of 1.43 mmol/g (∼147 mg/g), whereas anion-exchange resins barely adsorb Rh. The adsorption of ...

Sol-Gel Processing. Douglas A. Loy, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 IV.B.2 Supercritical Solvent Drying—Aerogels. Aerogels are low-density gels that retain a significant portion of their original volume (Fig. 6).Labeled as "solid smoke," aerogels can be prepared with densities as low as 0.01 g/ml.The time and cost of supercritical aerogel ...
Review of aerogel-based materials in biomedical applications
PMID: 33600880. DOI: 10.1016/j.jconrel.2021.02.012. Aerogels are the lightest processed solid materials on Earth and with the largest empty volume fraction in their structure. Composition versatility, modularity, and feasibility of industrial scale manufacturing are behind the fast emergence of aerogels in the drug delivery field.
