Aerogel is a nanoporous solid material with ultrahigh porosity, ultralow density, and thermal conductivity, which considered to be one of the most promising high-performance insulation materials today. However, traditional pure inorganic aerogels (i.e., silica aerogel) exhibit inherent structural brittleness, making their processing handling difficult, manufacturing costs are relatively high, l...

Abstract This study is aimed to investigate the effect of carbon nanotubes on properties lightweight aggregate concrete containing expanded glass and silica aerogel. Combinations (55%) hydrophobic aerogel particles (45%) were used as aggregates. Carbon sonicated in water with polycarboxylate superplasticizer by ultrasonication energy for 3 min. Study results show that incorporating multi-wall s...

A facile method for synthesis of amino functionalized silica coated Fe3O4 magnetic nanoparticles is introduced. For this purpose, the surface of magnetic nanoparticles (MNPs) was modified with two precursors of silica which produced amine and vinyl functional groups on the surface of magnetic nanoparticles. The modified magnetic nanoparticles were characterized by transmission electron micr...

The fine-mesh phototube is one type of photodetector which can be used under a strong magnetic field. For an aerogel readout, the single-photon detection efficiency should be close to 100% in order to identify particle species. We carried out a feasibility study of single-photon counting using fine-mesh phototubes, and obtained a possible solution.

The purpose of the study is preparation silica aerogels by using hydro(solvo)thermal synthesis assisted sol-gel method, SiO2 particle-added aerogels, and investigation their potential use in environment energy fields. It has been observed that prepared can be used as an adsorbent for organic contaminant removal applications. progressed rapidly reaction NaBH4 with methanol particle embedded aero...

— This lecture summary provides a short but comprehensive overview on the “energy and buildings” topic. Buildings account for roughly 40% of the global energy demands. Thus, an increased adoption of existing and upcoming materials and solutions for the building sector represents an enormous potential to reduce building related energy demands and greenhouse gas emissions. The central question is...
