A three-dimensionally interconnected graphene-reinforced Cu (3Di Gr-Cu) composite was synthesized using a simple two-step process technique which involves the mechanical compaction of micronsized particles followed by chemical vapor deposition (CVD) at 995 ℃. The microstructural properties pure and 3Di Gr-Cu were investigated optical microscope, scanning electron X-ray diffractometer. electrica...

this study was conducted to determine the effects of different levels and sources of copper supplementation on hematological values, ceruloplasmin and plasma copper, zinc and iron status in mehraban male lambs. twenty growing lambs were randomly allotted to four different treatments. treatments consisted of 1) 10 mg/kg cu in the form of cuso4, 2) 20 mg/kg cu in the form of cuso4, 3) 10 mg/kg cu...

The textile industry is the main source of environmental pollution in terms quality and quantity. It consumes large amounts water (200 m3/ tonne products), around 90% quantity wastewater. Improper disposal wastewater will cause serious problems due to presence heavy metals waste which adversely affect aquatic organisms. To analyze, concentration (batik) was collected from 15 small, medium, larg...

We explored in 51 normal subjects, distributed in various series of experiments, whether endothelium nitric oxide may play a role in insulin modulation of alpha2- and beta-adrenergic- evoked vascular responses. In particular, we examined the forearm blood flow response (FBF, ml.min-1.dl-1) to intrabrachial infusion of BHT-933 (0.5, 1, and 2 microg.min-1.dl-1) or isoproterenol (1, 3, and 6 ng. m...

for Session – 3 Hydrogen from Coal The Influence of Copper Concentration on the Permeability of Pd-Cu Alloy Membranes Bryan D. Morreale, Bret H. Howard US Department of Energy, National Energy Technology Laboratory PO Box 10940, Pittsburgh, PA 15236 Abstract Hydrogen membranes have been identified as a promising technology for extracting pure hydrogen from processes such as coal gasification, h...

Green mussels are marine organisms that threatened due to heavy metal pollution such as lead and copper in waters. In addition, threatening shell metals also a threat symbiont organisms. Bacteria exposed continuously will later be able adapt (resistance) contamination. This study aims determine the concentration of (Pb) (Cu) green from Lampung Bay test resistance symbiotic bacteria Pb Cu well c...

Abstract. Saleh LIF, Rashed RO, Muhammed SM. 2021. Evaluation of heavy metal content in water and removal metals using native isolated bacterial strains. Biodiversitas 22: 3163-3174. Natural surface sources are susceptible to chemical contamination, including metals. The goals this study were isolate naturally occurring metal-tolerant bacteria by evaluating their ability remove from Tanjaro Riv...

Al assisted alloying of carbon steel in Submerged Arc Welding (SAW) by Al-Cr-Ti-Cu unconstrained metal powders is applied. A base case without powder additions compared to two addition schedules, Al-Cu-Ti and Al-Cu-Ti-Cr. used as a deoxidiser element control the oxygen partial pressure at weld pool–molten flux interface ensure that most Ti Cr transferred into pool ppm O controlled within accept...

The antioxidant enzymes copper/zinc (Cu-Zn) and manganese (Mn) superoxide dismutase (SOD) have been implicated in protection of the lungs from oxidant damage. Mn SOD in particular may be related to acquired tolerance in cells following chronic ozone exposure. In order to study these protective and adaptive phenomena in oxidant injury, the cellular location and relative abundance of Mn SOD and C...

Crude rhizome extracts and volatile oils of Curcuma aromatica were evaluated for chemical composition and anti-mosquito potential, including larvicidal, adulticidal, and repellent activities against the Aedes aegypti mosquito. Chemical identification achieved by GC/MS analysis revealed that xanthorrhizol, 1H-3a, 7-methanoazulene and curcumene at 35.08 and 13.65%, 21.81 and 30.02%, and 13.75 and...
