The low-temperature epigenetic and stratabound Pb-Zn-Cu-Ba-F-Sr-bearing ore deposits enclosed within sedimentary columns historically have been major sources of metals.We report on a controlled synthesis of MAl2O4 (M = Mg, Co, Ni, Zn, Ba) nanopowders. The method includes three main steps: (i) growth of ultraporous nanofibrous Al2O3 monoliths (UPA) and their ...Section snippets Experimental procedure. Binary Mg-Zn and ternary Mg-Zn-Ba alloy, having the compositions given in Table 1, were prepared from pure elements by induction melting under protective Ar atmosphere and cast as ∼50. g ingots into a permanent mould made of steel.. The alloy ingots were homogenized and then aged as described in Table 1.Mississippi Valley-type (MVT) Pb-Zn(-Ba-F) ore deposits typically occur in undisturbed platform carbonates that preclude geologic dating, are comprised of minerals that are not amenable to radiometric age dating, and therefore have an uncertain age and genesis. This chapter summarizes palaeomagnetic methods that have been successful in dating ...

The semi-auto SKS fired a miniaturized version of the 7.62×54 round, the 7.62×39, and as such was one of the first guns chambered for what would become one of the most widely-used cartridges in the world. Oddly, considering how many SKS carbines are floating around these days, the SKS had a relatively short service life in the Red Army. The ...The change in peak position (2θ) along (101) plane is shown in Fig. 2.The peak position is shifted towards higher 2θ side (Δ2θ ∼0.001°) when 0.5% of Ba is introduced into the Zn-O lattice. The peak position is further shifted by 0.019° when Ba concentration is increased from 0.5 to 2% and the shift is clearly shown in Fig. 2.Further increase of Ba-doping concentration beyond 2%, the ...1. Introduction. Environment pollution with heavy metals is one of the most serious problems, since metals, even in traces, can be toxic and detrimental for living organisms [].Zinc is an essential element involved in different metabolic processes and an important component of more than 200 enzymes [].At the same time, zinc compounds are widely used in different industrial processes, which ...Introduction. The SKS was adopted by the Soviet Union in 1946 and is the basis for the later AK series of weapons. It is a gas-operated, semi-automatic rifle and might be referred to as a miniature version of the 14.5mm PTRS semi-automatic antitank rifle used during World War 2. The SKS and the PTRS were designed by the famed Russian arms ...铁锰结核中主微量元素的赋存形式研究对于理解铁锰结核的形成及其中元素的进入过程具有重要意义。选择采集自南海蛟龙海山水深约3 300 m的3个铁锰结核，根据其内部剖面上原位x荧光光谱分析(xrf)的主量元素含量差异分层进行了分层取样。对于分层样品开展了淋滤实验，分别提取样品中的碳酸盐相 ...
