Glasses with compositions (100-x) % Na2B4O7–x % MO (X=10,20,30,40) where (M) is Ba, Mg and Ca, are prepared using conventional melt quenching method. X-rays diffractions are performed. The result of (XRD) confirm the a...

We present DC conductivity measurements of newly synthesised and thermally annealed (As2S3)1-x (Bi2S3)x (0.08 ≤ x ≤ 0.14) glasses. X-ray diffraction measurements show that as-prepared As2S3)1-x(Bi2S3)x glasses we...

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...

Glasses of the composition (70–X) mol.% Ga2S3 - 30 mol.% La2S3 - X Er2S3 (at X = 0, 1, 3) were synthesized and the optical absorption spectra at room temperature were studied. Photoluminescence spectra in the 2.53 - 0...

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...

Glasses-free augmented reality is of great interest by fusing virtual 3D images naturally with physical world without the aid of any wearable equipment. Here we propose a large-scale spatial multiplexing holographic see-...

Iron oxides in macro/mesoporous bioactive glasses were characterized by synchrotron X-ray absorption near edge structure (XANES) spectroscopy. This magnetic phase was introduced by adding Fe(NO3)3 9H2O during the sol-gel...

In lightweight augmented reality (AR) glasses, the light engines must be very compact while keeping a high optical efficiency to enable longtime comfortable wearing and high ambient contrast ratio. “Liquid-crystal-on-s...
