The metal chloride of LaCl3 was chosen to modify the Au-Cu/AC to decrease the noble metal of gold and enhance the catalytic performances. Then a mercury-free catalyst of Au-Cu-La/AC was prepared by the impregnation method, and the fresh Au-Cu-La/AC and Au-Cu/AC catalysts were also characteri...

The PHENIX Experiment at the Relativistic Heavy Ion Collider has conducted a survey of fluctuations in charged hadron multiplicity in Au+Au and Cu+Cu collisions at √ sNN = 22, 62, and 200 GeV. A universal power law scaling for multiplicity fluctuations expressed as σ2/μ2 is observed as a function of Npart for all species studied that is independent of the transverse momentum range of the measur...

The impedance mismatch technique has been used for shock pressure amplification in two and three layer thin planar foil targets. Numerical simulation results using one dimensional radiation hydrocode MULTI in two layer targets consisting of Al-Au & Al-Cu and three layer target consisting of Plastic Al -Au & Foam-Al-Au respectively are presented. These results show a pressure enhancement up to 2...

We present recent results obtained by the BRAHMS experiment at the Relativistic Heavy Ion Collider (RHIC) for the systems of Au + Au and Cu + Cu at √ s N N = 200 GeV and at 62.4 GeV, and p + p at √ s N N = 200 GeV. BRAHMS explores reaction dynamics and properties of the hot and high energy density matter produced in ultra-relativistic heavy-ion collisions versus its longitudinal expansion. Over...

The effect of Au addition on the microstructural and the tensile properties of Sn–0.7 mass%Cu alloy was examined. Tensile strength and 0.2% proof stress remarkably increase up to 0.3 mass%Au primarily due to solid solution hardening. Beyond 0.3 mass%Au, due to precipitation of large intermetallic compounds, elongation decreases while tensile strength and 0.2% proof stress increase slightly. Wit...

Juvenile rainbow trout (Oncorhynchus mykiss) maintained on either low sodium chloride (LS (control), 1.4% NaCl) or high sodium chloride (HS, 11% NaCl) diet were exposed to 55 μg·L–1 waterborne copper (Cu) for 28 days. Cu-exposed fish maintained on the LS diet exhibited 26% mortality, more than double (11%) that in fish maintained on the HS diet. Waterborne Cu exposure inhibited growth by 56% in...

Particle production in Au−Au, Cu−Cu, d−Au and p−p collisions at 200 GeV c.m. energy are analyzed in the wounded quark-diquark model. Existing data are well reproduced. Emission functions of wounded and unwounded constituents are determined. Implications for the collective evolution of the system are discussed.

Collective flow reflects dynamical evolution in high-energy heavy ion collisions. In particular, the strange hadron elliptic flow reflects early collision dynamics [ 1]. We present results from a systematic analysis of the centrality dependence of strange hadron elliptic flow (v 2) measurement of K 0 S , Λ and Ξ for Cu + Cu collisions at 200 GeV. Results for Cu + Cu collisions are compared with...
