“…Selective internal radiation therapy of hepatic malignancies is a ground breaking therapeutic modality that needs the combined efforts of multiple medical disciplines to ensure the safe delivery of 90 Y-labelled microspheres in the studies of Westcott et al [126]. Materials with light-weight, high-strength and low thermal conductivity were manufactured by bonding HGMs with different content of ACP and TEOS by the study of Wang et al [127]. The super-hydrophobic and IR-reflectivity HGMs was synthesized by being coated with anatase TiO 2 and a super-hydrophobic material by Yan et al [128].…”

Glass microspheres are microscopic spheres of glass manufactured for a wide variety of uses in thermal insulation coating, putty, plastic casting polyester, radome, synthetic foam, adhesives, printed circuit board substrate, bowling, fan blades, and caulking materials, emulsion explosives, golf, sealant, pipeline insulation materials, artificial marble, PVC, low density oil drilling, light cement etc. Glass microspheres are usually between 1 and 1000 micrometres in diameter, although the sizes can range from 100 nanometres to 5 millimetres in diameter. Microspheres are spherical particles that can be distinguished into two categories; solid or hollow. This paper presented a general overview of glass microspheres.

The saturation-free and directionless cross-linking and interpenetration processes between La 3+ and [(H 2 PO 4 )2Al(HPO 4 )]-plasma in La−Al phosphate by mixing Al(OH) 3 , CrO 3 , and H 2 O 2 dissolved in H 3 PO 4 and La 2 O 3 as a curing accelerator, as well as the thermal stability of the La−Al phosphate bulk materials and the evolutions of the phase composition and morphology at different temperatures were studied using thermogravimetric/differential scanning calorimetry under different temperatures in a muffle furnace. The La−Al phosphates showed good thermal stability, and the thermal weight loss rate of the materials decreased from 18% before heat treatment to ∼2% after heat treatment. In addition, the La−Al phosphate bulk material showed excellent resistance to ablation when subjected to ablation by an oxyacetylene flame at 2000 °C for 30 s. It evolved into a dense LaPO 4 and AlPO 4 high-temperature phase layer on the sample surface, which prevented further ablation damage to the sample and significantly improved the temperature resistance of the La−Al phosphate bulk material.

“…1 With stimulating demand for energy efficiency in the building envelope, the thermal insulation coatings have attracted much attention on solving solar radiation heating problems. 2,3 To cut down the undesired heat loss, it can be easily achieved by stuffing the wall thickness using conventional thermal insulation materials such as mineral wool, phenolic resin composite, polyurethane material, 4 expanded polystyrene (PS), 5 or extruded PS; however, increased wall thickness is unfavorable as actual floor space is lost, and these materials are at risk of flammability, or install super-insulated materials such as aerogel blankets or vacuum insulation panels. 6 What’s more, the major defects with those state-of-the-art thermal insulation materials today are their high cost, fragility, risk of puncturing, and aging issues 7 that hinder their practical use in many areas.…”

Hollow silica nanospheres (HSNs) were synthesized via sol–gel method followed by calcination, using positively charged polystyrene (PS) as a hard template, and the tetraethoxysilane as precursor. The inner diameter and shell thickness of the HSNs can be expediently controlled by adjusting the particle size of PS and the amount of ammonia, respectively. The average inner diameters of HSNs increased from 153 nm to 255 nm along with the increasing PS particle size from 150 nm to 300 nm. The shell thickness of HSNs decreased from 20 nm to 12 nm with the increasing amount of ammonia from 1.5 mL to 3.0 mL. The structure of HSNs was verified by Fourier-transform infrared, thermogravimetric, scanning electron microscopy, and transmission electron microscopy characterization. The prepared thermal insulation coating comprised of HSNs shows good temperature retention and thermo-insulating properties, which indicate that the as-prepared HSNs are potentially used as an inorganic filler for thermal insulation coating.
