The present is a review on the development of TLD phosphors and composite materials for
possible applications in dosimetry using thermoluminescence (TL) as a measuring …

The complete conversion from Si into Si 3 N 4 was achieved after 2 h nitridation at 1400° C
by using in-situ formed Fe 2 O 3 nano-particles (NPs) as a catalyst. Such a synthesis …

Abstract Topaz (Al 2 F 1· 44 (OH) 0· 56 SiO 4)/corundum (Al 2 O 3) composites were
prepared by a facile and novel reversible process from the sintering of synthetic topaz and …

Albeit the thermoluminescent properties of both Al 2 O 3 and natural topaz have been
documented, owing to a controlled composition, the prospective of synthetic topaz for …

In this paper, we construct a SixFy (x≤ 6, y≤ 12) series optimised at the B3LYP/6-31G (d, p)
level. At the same level, we perform frontline molecular orbital (FMO), Mayer bond order …

A novel synthesis route for topaz (Al 2 SiO 4 (OH, F) 2) by chemical vapor deposition (CVD)
using Na 2 SiF 6 as solid precursor was developed. Synthesis tests were conducted with …

Because of variations in composition and the ensuing properties of mineral topaz, synthetic
topaz offers to be a promising candidate for advanced applications. The thermoluminescent …

This contribution presents a critical review about some materials used in dosimetry and the
interest that has emerged on topaz recently. In addition, results about the feasibility for …

Si3N4 is a ceramic material with important properties among which are fracture and tensile
strength resistance, dielectric properties, thermal shock resistant and optical radiation [1-3]. It …

An L8 Taguchi experiment was designed and conducted to determine the quantitative effect
of processing parameters (test temperature and time, nitrogen gas flow rate, NH4OH …
