Superfocus Launches Next-Generation Adjustable Focus Eyeglasses

Superfocus LLC, creators of award-winning / revolutionary adjustable focus eyeglasses, today launched its new Leonardo Collection. Leonardo offers alternative style, togeth...

Structural glasses: Flying to the bottom

It has been shown that glasses prepared by physical vapour deposition have extraordinary stability. A computer algorithm that mimics such a process has now identified the optimal deposition temperatur...

Anomalously slow crystal growth of the glass-forming alloy CuZr

The development of metallic glasses is hindered by the lack of mechanistic understanding of why some alloys crystallize quickly and thus are poorer at forming glasses than those that crystallize slowl...

New technique shows promise in restoring near vision without glasses

(Wolters Kluwer Health) By middle age, most people have age-related declines in near vision requiring bifocals or reading glasses. An emerging technique called hyperopic orthokeratology may provide a...

Next generation 3-D theater: Optical science makes glasses a thing of the past

WASHINGTON, Aug. 20—From the early days of cinema, film producers have used various techniques to create the illusion of depth – with mixed results. But even with digital technology, the latest Ho...

Vision Without Glasses Review Released Today By Duke Peterson And HeresToLife.net

Vision Without Glasses review was launched today and is a unique program that can help to bring back 20/20 vision and give one the opportunity to finally throw those glasses away. Scottsdale, AZ (PRWE...

3-D movies in your living room -- without the glasses

(Fraunhofer-Gesellschaft) New television screens will make it possible for viewers to enjoy three-dimensional television programming without those bothersome 3-D glasses. Still, the content has been r...

Students set to end the stigma of wearing glasses

(Aarhus University) Five students from Aarhus University, Business and Social Sciences, have qualified for the final in the annual Financial Times MBA Challenge. The students want to change attitudes...

Synthesis, bioactivity and preliminary biocompatibility studies of glasses in the system CaO-MgO-SiO(2)-Na (2)O-P (2)O (5)-CaF (2).

New compositions of bioactive glasses are proposed in the CaO-MgO-SiO(2)-Na(2)O-P(2)O(5)-CaF(2) system. Mineralization tests with immersion of the investigated glasses in simulated body fluid (SBF) at...

Origin of thermally induced second harmonic generation in PbO-B₂O₃ glasses.

Optical second harmonic generation (SHG) with second-order nonlinearity χ(2) as high as 2.1  pm/V has been achieved in water quenched PbO-B2O3 glasses. No nonlinear depletion layer or microcrysta...

Structure of Nb(2)O(5)-NaPO(3) glasses by X-ray and neutron diffraction.

X-ray and neutron diffraction of excellent resolving power are used to determine the atomic structure of niobium phosphate glasses. These studies complement the results of earlier (31)P and (93)Nb nuc...

Resolving structural modifications of colloidal glasses by combining x-ray scattering and rheology.

Glasses have liquid-like structure, but exhibit solid-like properties. A central question concerns the relation between the structure and mechanical properties of glasses, but structural changes remai...

Optical transitions of Eu³⁺ and Dy³⁺ ions in lead phosphate glasses.

Lead phosphate glasses containing Eu3+ and Dy3+ have been studied. Local structure was verified using Fourier transform (FT)-IR spectroscopy. Emission bands of Eu3+ and Dy3+ ions in lead phosphate gla...
