亚硒酸锌制备

将硫酸锌的溶液和亚硒酸钾的溶液混合生成白色的无定形沉淀，使沉淀与少量亚硒酸一起加热，即可转变为细小的结晶粉末，这是一水亚硒酸锌ZnSeO3·H2O的结晶。这种水合盐在空气中及加热到100℃都是稳定的。将这种一水合物同浓度为52.86%的亚硒酸溶液一起加热即可生成无水亚硒酸锌的结晶。从亚硒酸锌的酸性溶液中也可以结晶出二水亚硒酸锌ZnSeO3·2H2O。将这种水合盐加热到200℃，即可制得无水亚硒酸锌。

Polycrystalline ZnS(x)Se(1 - x) thin films deposited on ITO glass by MBE.

J. Zhejiang Univ. Sci. 4(2) , 131-5, (2003)

MBE growth of ZnS(x)Se(1 - x) thin films on ITO coated glass substrates were carried out using ZnS and Se sources with the substrate temperature ranging from 270 degrees C to 330 degrees C . The XRD t...

The distribution of zinc selenite and expression of metallothionein-III mRNA in the spinal cord and dorsal root ganglia of the rat suggest a role for zinc in sensory transmission.

J. Neurosci. 19(6) , 2288-300, (1999)

Zinc appears to play a role in synaptic transmission in the hippocampus. We tested the hypothesis that zinc is similarly involved in sensory transmission by determining whether vesicular zinc and meta...

Depletion of vesicular zinc in dorsal horn of spinal cord causes increased neuropathic pain in mice.

Biometals 21(2) , 151-8, (2008)

Zinc enriched (ZEN) neurons and terminals are abundant in the rodent spinal cord. Zinc ions have been suggested to modulate the excitability of primary afferent fibers believed to be important in noci...
