(uncountable) A malleable, ductile, metallic element, resistant to corrosion, with atomic number 50 and symbol Sn. [..] + 添加翻译 英文-中文字典 錫 noun element [..] Tiles, galvanized tin or asbestos cement sheets used in construction roofs will be regarded as pucca materials. 在...
In α-Sn each tin atom has a tetrahedral coordi- nation at a Sn–Sn distance of 281 pm, while the coor- dination number in β -Sn is increased to 4 × 302 + 2 × 318 pm (Fig. 1). Tin is a relatively soft metal with a good ductility. This is the prerequisite for the use ...
Transparent conductive oxides are appealing materials for optoelectronic and plasmonic applications as, amongst other advantages, their properties can be modulated by engineering their defects. Optimisation of this adjustment is, however, a complex desig
In recent years, numerous examples of tin-polymetallic mineralization have been discovered in the southern Great Xing’an Range (SGXR), making the SGXR the most important Sn belt in North China. Among these newly explored deposits, the Weilasituo Sn-polymetallic deposit is the best suited for ...
The large Weilasituo Sn-polymetallic deposit is a recent exploration discovery in the southern Great Xing’an Range, northeast China. The ore cluster area shows horizontal mineralization zoning, from the inner granite body outward, consisting of high-T S
Organotin compounds have been widely used as pesticides during the last 20 years. Because of the rapidly growing importance of this group, many studies have been undertaken to establish synthetical routes and to test the physical, chemical, and most of a
During the later stages of accretion, conditions may have been relatively oxidising such that In behaved as a lithophile element with higher condensation temperature rather than as a volatile chalcophile element. Hence, the InY ratio of Earth's primitive mantle may be representative of the mixture...
a) copper b) calcium c) mercury d) tin Atomic Symbol: The atomic symbols are used in cases in which one or two lettered symbols will be more beneficial than when writing the whole name. For instance, this notation is named when writing the nuclide symbol...
Multiply-excited states in these subshells have much smaller statistical weights compared to the multiply-excited states of Sn, and so their relative contribution to the plasma emission is also much smaller. If instead one looks once again at open-4d-subshells but in a lighter element, such ...
In general, SnO2, a typical n-type semiconductor with a large bandgap (Eg = 3.6 eV at 300 K), is doped with a specific element, such as indium, niobium, tantalum, or antimony (Sb), depending on the purpose of application. In particular, ATO, which is Sb-doped SnO2, is a...
