—The recent discovery of herbivores that feed on Ni-hyperaccumulating plants and contain elevated Ni concentrations in their bodies suggests that Ni may be transferred to their predators. We tested this hypothesis using the high-Ni herbivore Melanotrichus boydi and four predator species: the spiders Pholcus phalangioides and Misumena vatia, the mantid Stagmomantis californica and the lacewing C...

Abstract:Electroless Nickel-phosphorus (EN) coatings provide high performance in various industrial fields due to their unique properties such as excellent corrosion and wear resistance. This paper aims to study the effect of ZnO nano-particles addition on corrosion behavior of EN coatings. Various amounts of ZnO nano-particles with average diameter of 50 nm were added to hypophosphite reduced ...

We show that there is a structure of countably infinite signature with P = N2P and a structure of finite signature with P = N1 P and N1 P N2P. We give a further example of a structure of finite signature with P : NIP and N1 P $ N2P. Together with a result from [10] this implies that for each possibility of P versus NP over structures there is an example of countably infinite signature. Then we ...

In this paper, we investigate the known operator inequalities for p-Schatten norm and obtain some refinements of these when parameters taking values in different regions. Let A1,...,An, B1,..., Bn ? Bp(H) such that ?ni,j=1Ai*Bj=0. Then p 2, 21/p-?/4n3/p-?/4-1/2(?ni=1 ||Ai||4/?p + ?ni=1 ||Bi||4/?p )?/4 n2/p-1/2||?ni=1 |Ai|2 |Bi|2||1/2 p/2 n2/p-2/?(?ni,j=1 ||Ai Bj||?p)1/?. For 0 < > are rev...

the kinetics of hydrogen evolution reaction (her) was studied in 1m naoh at various temperatures (298 to 358 k) on ni-p-c (composite electrodes. the electrochemical efficiency of the electrodes has been evaluated on the basis of electrochemical data obtained from the steady-state polarization tafel curves, electrochemical impedance spectroscopy (eis) and cyclic voltammetry (cv) in 1m naoh solut...

Despite the increasing interest in metallic glasses for a variety of engineering applications, the structure and corrosion properties still remain unknown. In particular, these properties for Ni P alloy, a typical metallic glass, are greatly dependent upon the phosphorus content in the alloy. In this report, a relationship between the structural property and the interface corrosion behavior of ...

Feasibility of an oxidized Ni/Au p contact on some aspects of device applications for a GaN/InGaN multiple quantum well light-emitting diode ~LED! was investigated. For the oxidation of Ni/Au p contact, furnace annealing of a completely fabricated LED was performed at 600 °C for 5 min in an O2 ambient. For the case of LED with an oxidized Ni/Au system, the I – V measurements showed a reduction ...
