We present passive UHF RFID electro-textile tags integrated into two types of gloves for wearable RFID applications. The performance of the electro-textile glove-tags is evaluated on a male test subject and the results are compared to glove-tags with copper tape antennas. Based on the achieved results, the read ranges of the electro-textile tags are very close to those of the copper tape tags and...
21 Sedimentary samples were taken from the rivers in north part of Anhui province, China. The contents of 8 heavy metal elements (Be, Cd, Cr, Cu, Pb, Ni, Mn, and Zn) were determined by ICP-MS. Organic matter contents in sediment were also tested. The results show that the different degree enrichments of heavy metals in sediments are appearing as compared with the average values of heavy metal contents...
Environmental quality of reclaimed soil is a key issue in the process of land construction and ecology rehabilitation. Taking Xinzhuangzi and Datong reclamation district for example, according to Nemerow Pollution Index Method, results show that: In all 30 soil samples, 28 samples are I class level, clean; 1 sample is II class level, slightly clean; 1 sample is III class level, polluted slightly....
Wide dispersions of memory switching parameters are observed in resistive random access memory based on Al/CuxO/Cu structure. Moreover, the switching instability induced by these dispersions is studied. In this letter, a ramped-pulse series operation method is put forward, which can improve switching stability and cycling endurance remarkably. A method for minimizing the dispersion of Vreset by optimizing...
We have discovered a new Cu-based bulk metallic glass (BMG). Although of a simple Cu 49 Hf 42 Al 9 ternary composition, the as-cast alloy is a monolithic, uniform BMG with a critical diameter as large as 10mm. The width of the supercooled liquid region ΔT x and the reduced glass transition temperature T rg for this glass are 85K and 0.62, respectively. In addition...
