A few days ago, Advanced Functional Materials, an authoritative journal in the field of functional materials, published the latest research results of Northwestern Polytechnical University on new metal dual-activity catalytic materials for fuel cells. The title of the thesis is: "One-pot Synthesis of Dealloyed AuNi Nanodendrite as a Bifunctional Electrocatalyst for Oxygen Reduction and Borohydride Oxidation Reaction", DOI: 10.1002/adfm.201700260. The first author is a doctoral student directed by Prof. Chen Fuyi of the Material Institute of West University of Technology Wang Jiali and Chen Fuyi. Professors are co-authors, Yu Yachao, Lei Yimin and others are collaborators.
For the first time in this research work, a flexible and controllable one-step electrochemical method was created. The de-alloyed AuNi multilayered nano-dendrites were successfully synthesized. More importantly, the de-alloyed AuNi nano-dendrites prepared by this one-step method are superior to those prepared by conventional multi-step de- alloying of AuNi, demonstrating its great application value in the field of fuel cells. In addition, this research work further verified the rationality and versatility of the one-step method through systematic experiments, thus providing a brand-new idea for the development of the next generation of new electrocatalytic materials.
We can produce the lower-temperature Steel Pipe according to the ASTM A333 and ASME SA333 standards, and the and the production diameter from 8" to 48" in OD and wall thickness from 9.53 mm up to 140mm. We have been sold the GR.6 steel pipe about 20000 tons to date and the property of -45℃ impact value is about 100J, better than the standard`s requirements.
Yangzhou Chengde has the full capability to do every test in-house, from mechanical testing, chemical analysis, PMI, UT/Hydrotest etc. Chengde`s lab is qualified to ISO 17025 and CNAS standard, being proven the repeatability of accurate testings.
Each alloy pipe is subject to PMI before dispatch. The INNOV-X system performs non-destructive chemical analysis via simultaneous detection and quantification of fluorescent x-rays of multiple elements in test sample.
