5 天之前 · The emergence of electrochemical discharge machining (ECDM) has demonstrated as promising method for creating micro-holes in tough and brittle materials like glass. This technique employs localized Joule heating of material to facilitate its controlled removal. Nonetheless, there are still several critical issues that need to be tackled during drilling of micro-holes. These are …

The STL data from the desktop scanner provided a further visual gold standard with which the accuracy of the experimental subgroups could be compared to the control subgroup.

2025年1月31日 · Optical Metasurfaces (MSs), a new class of planar optical elements, are profoundly disrupting the field of optical design, notably due to their compactness, multi-functionalities, and device ...

2025年1月29日 · The circular marks on the glass surface are referred to as suction cups or roller marks. These marks may occur on the glass surface as a result of using suction cups to move the glass during the manufacturing process.

2025年2月8日 · The number of glass-houses in England in 1696 is said to have been eighty-eight, but how many of these were in Middlesex cannot be ascertained. An important discovery in glass manufacture made by Thomas Tilston, a merchant of London, early in the reign of Charles II, gave London glass a great reputation both here and abroad.

2025年1月31日 · In this lesson, artist Ted Sawyer demonstrates his approach to working with powder on sheet glass while making two of his signature pieces. The lesson spans three days and multiple firings. It covers Sawyer’s approach to everything from preparation to …

2 天之前 · As described in Ref. 30, the nanoparticles were deposited on planar glass substrates and initially oriented along the same direction (x) by an external magnetic field. The use of a magnetic field sensor based on the giant magnetoimpedance effect (GMI) enabled the determination of the magnetic field H at a fixed distance from the planar ...

3 天之前 · Tempered glass, also known as toughened glass or safety glass, is a type of glass that undergoes a special heat treatment to make it significantly stronger than regular glass. This strength and its shatterproof design make it safer and reduce injury risks when broken into jagged shards, making it the ideal choice for both residential and ...

2025年1月17日 · Production of raw glass was undertaken in geographically separate locations to the working of glass into finished vessels, and by the end of the 1st century AD large scale manufacturing resulted in the establishment of glass as a commonly available material in the Roman world, and one which also had technically very difficult specialized types ...
