Phase equilibria of the quasi-ternary systems Ag2S–BIVS2–CV2S3 (BIV– Ge, Sn; CV–As, Sb) were investigated using phase analysis based on XRD. Isothermal sections at 500 Kand glass formation regions in the respecti...

This study fabricates 50SiO2・50GeO2 and 50SiO2・(50-x)GeO2・xR2O (R: Na, K, Rb, and Cs, x = 5?40) glasses using the conventional melt-quenching method. Their photoluminescence characteristics were investigated by mea...

With the use of small unmanned aerial systems (sUAS) proliferating throughout industry and public safety, it is imperative to ensure safety of flight. The Federal Aviation Administration (FAA) published regulations for c...

Abstract BackgroundSmart glasses might present a promising solution to support older adults with cognitive impairment in maintaining independence. However, there exists a critical gap in smart glasses researc...

Since lithium (Li+) plays roles in angiogenesis and osteogenesis, the localized and controlled release of Li+ ions from bioactive glasses (BGs) represents a promising alternative therapy for bone regeneration. This chapt...

Recent days the special interest towards Glasses is specifically due to their vast applications that they range. Glass series Calcium borate metallic glass (CaO–B2O3) has been prepared by melt quenching technique. CaO ...

We study the dynamics of an asymmetric intruder in a glass-former model. At equilibrium, the intruder diffuses with average zero velocity. After an abrupt quench to T deeply under the mode-coupling temperature, a net ave...

Abstract Calcium aluminate cement (CAC) is a suitable source of tetrahedral aluminum, which reacts with tetrahedral silicon from water glass (aqueous sodium or potassium silicate solution) in an exothermic reaction, form...

Abstract Objective To investigate the application effect of 3D printing combined with MR technology in teaching the percutaneous screw fixation of scaphoid fractures under C-arm fluoroscopy, providing new ideas to enhanc...

In this work, we have performed a comprehensive investigation of the Ag+ concentration effect on the morphological, thermal, structural, and mid-infrared emission properties of novel oxyfluoride borosilicate glasses and ...

The specific features of using chalcogenide alloys of the nonstoichiometric ternary system (As2S3)x(Ge2S3)1-x in dosimetry of high-energy γ-radiation are analyzed. It is shown that when developing dosimetric systems bas...

Natural hydrogels are widely used for 3D-bioprinting because of their qualities fortissue engineering. Recently, hydrogels have been combined with bioactive glasses,due to their angiogenic properties that aid tissue rege...

An all-solid waveguide array fiber (WAF) is one kind of special microstructured optical fiber in which the higher-index rods are periodically distributed in a low-index silica host to form the transverse two-dimensional ...

Latar belakang masalah. Restorasi dari cacat masalah. Restorasi dari cacat yang disebabkan tumor di daerah fasial sangat menantang bagi dokter bedah dan ahli prostodonti. Maxillofacial prosthetics adalah cabang kedoktera...

Conventional optical fiber has excellent performance in guiding light, which has been widely employed for long-distance optical communication. Although the optical fiber is efficient for transmitting light, its functiona...

Objective: To investigate the prevalence of dry eye syndrome (DES) and its association with risk factors among university students. Methods: This cross-sectional study was conducted between May and November 2019 with 40...

Virtual reality (VR) is one of the most common technologies nowadays, which make a virtual environment exactly similar to the real environment. The purpose behind this is to test several issues (designing or manufacturin...

The starting material was melted at 1,100-1,300 °C in an air atmosphere and then naturally cooled, and Ca(La1-xDyx)B7O13 (x = 0.01-0.30), MII(La0.94Dy0.06)B7O13 (MII: Mg, Ca, Sr, Ba), Ca(REIII0.94Dy0.06)B7O13 (REIII: La...
