Tin dioxide is one of the most important n-type metal oxide wide band gap semiconductors (E g = 3.6 eV at 300 K) [ 1 ]. Because of its unique electronic, optical, electrochemical and catalytic properties, it has been
A rapid method is described for the determination of tin in biological material, using123Sn (T=40 m). The chemical procedure is based on the nearly quantitative extraction of tetravalent tin into toluene from an
acid 1.3M iodide solution. The recovery is determined by spiking the solution with113Sn and measuring the activity of the113mIn daughter in the counting sample. The lower limit of the determination is ≃0.01μg. Results are given for standard kale powder
and dried animal blood.
Cobalt—tin alloys electrocodeposited from a mildly alkaline sulfate bath were studied using119Sn absorption and57Co Emission Mössbauer Spectroscopy. The Results reveal that dissolved tin and cubic CoSn (not appearing in the phase diagram) are the components obtained from fresh plating solutions. Upon exhaustion, the formation of
Co3Sn2 is favoured, with the eventual deposition of cobalt particles as a separated phase. A precipitate is formed during bath operation which is richer in Sn(II), contrasting to the mother solution which is richer in Sn(IV).

A short review of the thermal analysis data available for dithiocarbamate complexes of tin(II) and tin(IV) is presented. Since
the relevant thermal decomposition mechanisms are complicated, even for decompositions in inert atmospheres, mechanisms postulated
on the basis of thermal analysis data alone are suspect. Realistic thermal decomposition mechanisms for these complexes can
only be formulated when the relevant decomposition products are unambiguously identified. In this short review, an attempt
is made to identify trends in these thermal analysis data, with particular reference to structural features of the corresponding
A method was developed for the determination of 15 trace elements in tin. High-purity tin samples (99.9999% and 99.999%) as
well as tin of technical quality were analysed. Reactor neutron activation of the tin samples was followed by distillation
of the matrix activities from a HBr−H2SO4 medium and Ge(Li) gamma-ray spectrometry of the distillation residue. The sensitivity of the method is generally high. For
the high-purity samples the detection limits vary from 0.02 ppb (scandium) to 200 ppb (iron) for irradiation of 1 g of tin
for 1 week at a thermal flux of 5·1012n·cm−2. ·sec−1. To decontaminate the surface of the tin samples, pre- and post-irradiation etching procedures were applied. The efficiency
of these etching techniques was studied.
