"...museum workers are more likely to be exposed to low-level doses of heavy metals over an extended period of time, resulting in chronic health problems. Heavy metal exposure in the environment along with that from museum collections and buildings is of particular concern to museum professional...
Metals Used to Color Glass The recipe for producing colored glass usually involves the addition of a metal to the glass. This is often accomplished by adding some powdered oxide, sulfide, or other compound of that metal to the glass while it is molten. The table below lists some of the c...
This range includes pigments made from aluminum, bronze, stainless steel, iron, zinc, lead, nickel, copper and a host of other metals. Metallic pigments are produced in a variety of shapes and sizes ranging from lamellar to spherical to spindle shaped. Of the various pigment geometries, ...
Such LT growth can suppress the interfacial reactions between GaN and a chemically vulnerable substrate such as metals. In fact, LT epitaxial growth of GaN and AlN films on various single-crystalline metal substrates has been achieved19, 20. It should be noted that PSD is capable of industry-...
For fixed relative abundances of 'metal' atoms, stellar compositions are specified by mass fractions X for hydrogen and Z for metals (the helium mass fract... M.J.,Seaton - 《Monthly Notices of the Royal Astronomical Society》 被引量: 17发表: 1996年 Improving image quality of volume-rendere...
transmutation - (physics) the change of one chemical element into another (as by nuclear decay or radioactive bombardment); "the transmutation of base metals into gold proved to be impossible" damage, impairment, harm - the occurrence of a change for the worse development - a recent event tha...
perfect light absorption Fei Cheng1, Jie Gao1, Ting S. Luk2 & Xiaodong Yang1 Subwavelength structural color filtering and printing technologies employing plasmonic nanostructures have recently been recognized as an important and beneficial complement to the traditional colorant-based ...
Figure 30 clearly shows the orientation of slip bands in the grain microstructure in accordance with the grain orientation. This technique can be used for most etch-resistant hard metals to obtain a much better image of spherolithic carbides with their secondary adhesions – here embedded in a ...
The chart has a set of packaging materials representing determined sensory descriptors, where each packaging material is evaluated with respect to the determined sensory descriptors. The packaging materials are glass materials, ceramics, enamel, plastic materials, glass-ceramics, metals, fine card-boards...
aSo it was important to describe the partitioning of heavy metals into different fractions before and after their biological removal from mine tailings. 在他们的从矿跟踪的生物撤除前后如此描述分成重金属入不同的分数是重要的。[translate] a请输入您需要翻译的文本!Yes i translate through software 是我通...
