Abstract (sommario):
Self-cleaning glasses became demanding for various advanced applications due to their manifold advantages. In this view, some tellurite glasses containing TiO2 nanoparticles with varying concentrations were synthesized using the standard melt-quenching. These glasses were transparent with a reddish appearance. The HRTEM images of the glasses showed the presence of ellipsoidal TiO2 NPs with sizes ranging from 9−22 nm and 5−9 nm along the major and minor axis, respectively. The lattice fringe pattern of the selected TiO2 NPs confirmed their anatase structure with a lattice spacing of 0.36 nm. Th

Different amounts of iron oxide (Fe2O3) were added into a base calcium alumino-silicate glass (CaO 40, Al2O3 9, SiO2 51 wt%). The crystallization behavior of the glassed was investigated by DTA, XRD, SEM and optical microscopy. DTA analysis on the samples with and without the iron additions shows that the iron-containing glasses obviously absorb more heat energy than the base glass. All the glasses show two endothermal peaks correspondent to two transition temperatures, Tg1 and Tg2, indicating the existence of phase separation.

The term “halide glass” refers to glasses in which the anions are from elements in Group VIIA of the periodic table, namely, F, Cl, Br and I, as opposed, for example, to “oxide glasses,” such as silicates, borates, phosphates, etc. Two known single component halide melts are glassforming, BeF2 and ZnCl2, but the majority of halide glasses are multicomponent. Practical interest in halide glasses has been generated almost entirely by their optical properties, which cannot be duplicated in a more conventional oxide glass.

Even though oxygen is technically a chalcogen element, the term “chalcogenide glass” is commonly used to denote those largely covalent, semiconducting glasses which contain sulfur, selenium, or tellurium as one of the constituents.The chalcogenide gl

OVERVIEW On Earth, natural glasses are typically produced by rapid cooling of melts, and as in the case of minerals and rocks, natural glasses can provide key information on the evolution of the Earth. However, natural glasses are products not solely terrestrial, and different formation mechanisms give rise to a variety of natural amorphous materials. In this chapter, we provide an overview of the different natural glasses of non-magmatic origin and on their formation mechanisms.

Most organic and metallic glasses possess Poisson's ratio above 0.32, and thus, feature fracture energy that is around three orders of magnitude higher than that of oxide glasses, which feature Poisson's ratio typically below 0.30. However, whether the BTD transition can also be observed in oxide glasses remains unknown due to the lack of fracture energy measurements on oxide glasses with high Po

It was found that the addition of CuO significantly alters the nonlinear I–V characteristics of these glasses; while the glasses with x = 10 exhibit a current-controlled negative resistance behavior associated with a memory type transition, glasses with x = 15 show a threshold-type behavior. Remarkable differences were also noticed in the high-pressure electrical resistivity behavior between the low- and high-CuO-containing glasses. Corroborative therm

AbstractCast glass has great potential for diverse load-bearing, architectural applications; through casting, volumetric glass components can be made that take full advantage of glass’s stated compressive strength. However, the lack of engineering, production and quality control standards for cast glass and the intertwined ambiguities over its mechanical properties-particularly due to the variety in chemical compositions and the lack of understanding of the influence of flaws occurring in the glass bulk-act as an impediment to its wide-spread application. Addressing the above uncertainties, th

Abstract (sommario):
Wearable technology has become one of the most significant research areas today, offering both portability and solutions to various human needs. However, current smart glasses face challenges in hardware capabilities and user interaction. Despite their potential, smart glasses have not been embraced as widely as smartwatches and smartphones. Furthermore, existing smart glasses do not offer significantly greater functions to justify their higher prices compared to smartphones. Moreover, user feedback for smart glasses products like HoloLens indicates that these devices suffer from non-intuitive

Abstract (sommario):
Alkali oxy borate glasses are well known due to their variety of applications in phosphors, solar energy converters and in a number of electronic devices. These glasses have high mechanical strength when compared with the pure borate glasses. On the other hand heavy metal oxide (Bi2O3) glasses owing to high refractive index such glasses exhibit non-linear effects. Besides, high density and transparency of these glasses make them useful for a variety of optical applications such as radiation shielding windows and scintillation counters.

Abstract (sommario):
Oxide glasses having lower glass transition temperature are widely used in electric devices. The oxide glasses usually contain lead oxide. Recently, lead oxide glasses have been replaced with lead-free oxide glasses because of the environmental pollution. We investigated the thermal properties and the glass formation region in the Bi2O3-B2O3-ZnO ternary system. The results showed that the ratio of Tg/Tl of the bismate glasses is around 0.55, which is lower than the value of ratio 0.67, the two-third rule (Tg/ Tl=2/3)

AbstractTwo glass series in the ternary systems K2O-B2O3-SiO2 (KBS) and Na2O-B2O3-SiO2 (NBS) were studied in order to identify the main factors influencing the solubility of iodine. We established that iodine incorporation is strongly linked to the bulk chemistry, i.e. the SiO2/(B2O3+SiO2) molar ratio, and to the physical properties of the glasses, and we assessed three different solubility limits. Iodine in Si-rich glasses has a low solubility (≤1 mol% I) regardless of the alkali ion present. On the contrary, in B-rich glasses, the solubility is five times higher than in Si-rich glasses for N

Abstract The new recommendation of the International Commission on Radiological Protection for occupational eye dose is an equivalent dose limit to the eye of 20 mSv year–1, averaged over a 5-year period. This recommendation is a drastic reduction from the previous limit of 150 mSv year–1. Hence, it is important to protect physicians’ eyes from X-ray radiation. Particularly in interventional radiology (IVR) procedures, many physicians use protective lead (Pb) glasses to reduce their occupational exposure. This study assessed the shielding effects of novel 0.07 mm Pb glasses. The novel glasses

In face perception, besides physiognomic changes, accessories like eyeglasses can influence facial appearance. According to a stereotype, people who wear glasses are more intelligent, but less attractive. In a series of four experiments, we showed how full-rim and rimless glasses, differing with respect to the amount of face they cover, affect face perception, recognition, distinctiveness, and the attribution of stereotypes. Eyeglasses generally directed observers’ gaze to the eye regions; rimless glasses made faces appear less distinctive and resulted in reduced distinctiveness in matching an

However, in the studied Tm3+/Er3+/Yb3+co-doped oxyfluoride glasses, tellurite glass showed weaker UC emissions than germanate glass, which is inconsistent with the prediction from the difference of maximum phonon energy between oxyfluoride tellurite and germanate glasses.
