Although, unlike plastic, glass is spared the environmentalists' finger pointing to it as a polluting material, the process of its creation is not as friendly.Obviously, when opening a bottle of wine, one might possibly be concerned by the prospects of a terrible hangover rather than the impact that the creation... |

Some people, even today, call this type of material bulletproof glass. The fact is that it is anything but bulletproof. By definition, this special type of glass is able to resist one or more rounds shot from a firearm before losing the properties that allow it to stop bullets. Its primary objective is not even to st... |

Traditional glass mirrors used in telescope manufacturing are very expensive and extremely hard to build, not to mention that they weigh a 'ton' and are incredibly difficult to maneuver. And then there's always the risk that once completed, they may not turn out to be perfect for the job (remember Hubb... |

A one-way mirror is basically just like any other mirror, just that it has the ability of reflecting light on one side while on the other, it is transparent. Typical mirrors achieve a high degree of reflectiveness on one side, leaving the reverse opaque to optical light. This is done by covering the glass layer with ... |

Sunglasses are defined as an ophthalmologic medical article made of frames and lenses, meant to diminish the amount of sunlight; however, they do not accomplish any sort of optical correction. Their main goal is to protect the wearer against excessive sunlight. In many cases, we pay exaggerated amounts of money for t... |

There are two types of motion sensors currently commercially available, the active sensors and passive sensors. A motion sensor is classified as being active only when it emits some kind of energy into the surrounding medium to make an accurate reading, whether it is infrared light, microwave radiation or sound waves... |

The traditional fiber optic is virtually reduced to transmitting light through a narrow cylindrical glass core. However, this particular design imposes certain restrictions to sending light signals over great distances, such as the fact that the glass fiber optic is highly sensitive to powerful light signals, which c... |

The carbon nanopipette, which can also be used to inject certain fluids into cells without damaging or disable the growing of the respective cell, is the smallest of its kind, with a width measuring only a thousand of the diameter of a human hair. Such micropipettes made out of glass can be routinely found in researc... |

There are infrared glasses, protective ones, glasses that improve your vision and even 'over-the-top' glasses. But what about glasses that make you sleep in a nice and easy way? A team at John Carroll University, making investigations in its Lighting Innovations Institute, has come up with an affordable acc... |

A baby may be sunshine for the parents, but sunshine for the baby is really harmful. There is a higher risk of myopia later in life. About 25 % of myopia cases seem to be caused by a too great exposure to sunlight in the first weeks of life. It was already known that over-exposure to sunlight caused myopia in animals... |

Glass, even the one used in windows, has always fascinated scientists and not only due to its transparency. Like other solids, such as acrylic and polycarbonate, glass has a weird structure, which is not crystalline but disordered at the atomic scale.Essentially, glass is a liquid frozen in time. This freezing, howe... |

90 % of the way we perceive our environment comes through our eyes. We are mainly visual creatures. But modern lifestyle with so many hours spent in front of the TV or the computer's monitor is a strenuous task for our eyes. At birth, the greatest danger for the baby is represented by the infections of the corne... |

Plexiglas, in fact an acrylic glass, is the commercial name of Polymethyl methacrylate (PMMA) or poly (methyl 2-methylpropenoate) is the synthetic polymer of methyl methacrylate. It is thermoplastic - deformable, melts to a liquid when heated and freezes to a brittle, glassy state when cooled sufficiently - transpar... |

When you think of marine civilizations, your mind may go to Greeks or Vikings, but actually a much older one is that of the Phoenicians. They called themselves Canaanites and their land Canaan, located along the coastal plains of what is now Lebanon and Syria. The Phoenician cities were built on the coast, in places... |

A new research points out the fact that the smallest particles in lunar dust might be toxic, and could be a possible threat to astronauts inhaling them. These health effects have been signaled since NASA's Apollo missions. Astronaut Harrison H (Jack) Schmitt, the last man to step on to the Moon in Apollo 17, com... |

When you hear "glass", a window pane comes to mind. Ever tried bending one? Surely not, since most people are not very fond of glass shards. And yet, a new type of metallic glass bends in more than acceptable physical limits and "bends" again in commercial products like electric transformers, golfclubs and more. Ask ... |
