T1 - Use of corrosion resistant high-alloyed metallic materials for transport tanks of dangerous goods and water-polluting substances T2 - EUROCORR 2005 - Proceedings N2 - In Germany the “BAM-List – Requirements for Tanks for the Transport of Dangerous Goods” is the basis for substance-related prototype approvals for tank containers designed for the carriage of dangerous goods. Such approval is undertaken by the Federal Institute for Materials Research and Testing (BAM). Compatibility evaluations of selected metallic material groups as well as of polymeric gasket and lining materials under the influence of dangerous goods and water-polluting substances are published in section 5 of the BAM-List. According to the relevant regulations for rail, road and sea transportation a compulsory internal inspection after certain intervals is required. The required corrosion resistance depends on the length of the inspection interval. There is a large number of dangerous goods with a high corrosivity to metals, where the standard steels are not corrosion resistant. Chemical companies, transportation providers and tank producers need tanks made of corrosion-resistant materials in order to protect the tank shell and prevent contamination of high-value cargo as well as the environment. One solution is to line the tank with a polymeric material, an alternative solution to corrosion problems is the application of high-alloyed materials. Only a narrow limited number of corrosion test results of these high-alloyed materials under the influence of corrosive dangerous goods are available. In order to change this situation and include the superaustenitic steels X1NiCrMoCuN25-20-7 (Alloy 926), X1NiCrMoCu32-28-7 (Alloy 31) and the nickel-based alloy NiCr23Mo16Al (Alloy 59) in the BAM-List, BAM, IKS Dresden and ThyssenKrupp VDM started an comprehensive test program with welded specimens made. The program comprises corrosion resistance evaluations of the high-alloyed materials in substances representing 12 major groups of corrosive dangerous goods (e.g. inorganic halogenides, organic acidic halogenides, halogenic carbonic acids, chlorosilanes, chlorates, perchlorates, chlorites, hypochlorites and hydrogen sulphates). The test results, presented in this paper, will be included in the upcoming 8th edition of the BAM-List and therefore available for the costumer.

T1 - Spectroscopically well-characterized RGD optical probe as a prerequisite for lifetime-gated tumor imaging JF - Molecular imaging N2 - Labeling of RGD peptides with near-infrared fluorophores yields optical probes for noninvasive imaging of tumors overexpressing ανβ3 integrins. An important prerequisite for optimum detection sensitivity in vivo is strongly absorbing and highly emissive probes with a known fluorescence lifetime. The RGD-Cy5.5 optical probe was derived by coupling Cy5.5 to a cyclic arginine–glycine–aspartic acid–D-phenylalanine–lysine (RGDfK) peptide via an aminohexanoic acid spacer. Spectroscopic properties of the probe were studied in different matrices in comparison to Cy5.5. For in vivo imaging, human glioblastoma cells were subcutaneously implanted into nude mice, and in vivo fluorescence intensity and lifetime were measured. The fluorescence quantum yield and lifetime of Cy5.5 were found to be barely affected on RGD conjugation but dramatically changed in the presence of proteins. By time domain fluorescence imaging, we demonstrated specific binding of RGD-Cy5.5 to glioblastoma xenografts in nude mice. Discrimination of unspecific fluorescence by lifetime-gated analysis further enhanced the detection sensitivity of RGD-Cy5.5-derived signals. We characterized RGD-Cy5.5 as a strongly emissive and stable probe adequate for selective targeting of ανβ3 integrins. The specificity and thus the overall detection sensitivity in vivo were optimized with lifetime gating, based on the previous determination of the probés fluorescence lifetime under application-relevant conditions.

T1 - Recent experiences on suitability of titanium and high alloyed materials in acids at 200°C T2 - NACE International corrosion conference 2015 (Proceedings) N2 - In the literature there are not much data available to describe the corrosion behavior of titanium, nickel alloys and special stainless steels in acids at high temperature, in particular above the boiling point. Therefore, a laboratory testing program was performed with two titanium alloys (UNS R50400 and UNS R53400) to obtain corrosion data in formic acid, acetic acid, phosphoric acid, polyphosphoric acid, p-toluene sulfonic acid and lactic acid at 200 °C. Results were compared to previously published ones obtained on UNS N08031, UNS N06059 and UNS N10665. From the results it can be concluded that titanium does not always show better corrosion resistance than Ni-based alloys. UNS N06059 was the best choice for formic and acetic acids at temperatures of 200 °C. Both Ti-alloys are resistant in acetic acid. Some slight differences were observed for formic acid, where UNS R50400 is only resistant up to a 20 % solution and UNS R53400 in concentrated acid too. The phosphoric acid is extremely corrosive and none of the investigated materials was resistant. In the diluted acid (5 %) only UNS R53400 is resistant, whereas in 1 % solution all investigated materials performed satisfactory. UNS N10665 and UNS N06059 showed the best behavior in polyphosphoric acid. In 30 % concentrated p-toluene sulfonic acid at 200 °C all alloys tested were unsuitable. In very diluted acid (0.1 %) both Ti-alloys and the other three alloys behaved well. In lactic acid at 180 °C increased corrosion underneath deposits was detected; the best performance was observed for UNS N06059 and UNS R50400.

Therefore, a laboratory testing program was performed with two titanium alloys (grade 2 - UNS R50400 and grade 12 - UNS R53400) to obtain corrosion data in formic acid, acetic acid, phosphoric acid, polyphosphoric acid, p-toluene sulfonic acid and lactic acid at 200 °C.

From the results it can be concluded that titanium does not always Show better corrosion resistance than Ni-based alloys, Alloy 59 was the best choice for formic and acetic acids at temperatures of 200°C.

The phosphoric acid is extremely corrosive and none of the investigated materials was resistant. In the diluted acid (5 %) only Ti grade 12 is resistant, whereas in 1 % solution all investigated materials withstand. Alloy B-2 and alloy 59 showed the best behavior in polyphosphoric acid.
