In this review paper, recent studies on low-temperature sintering strategies of copper materials for conductive layer preparation have been summarized. Coinage metals, gold, silver, and used as inks pastes printed electronics. Copper is a highly electrically thermally material that can be in electronic circuits die-attach materials. Recently, copper-based inks/pastes gained significant attentio...

The objective of the present study was to investigate the validity of using holmium as a faecal marker in a copper absorption study using a highly enriched (65)Cu stable isotope label. Ten volunteers (nine female, one male) aged 24-55 years were recruited from the Norwich area to take part in a free-living study. The study was conducted in the Human Nutrition Unit at the Institute of Food Resea...

Copper (Cu) is an essential trace element involved in normal reproduction but its over-exposure may produce some detrimental effects. The aim of this study was to investigate the effects of purslane on copper sulfate poisoning on liver structures changes. Twenty eight wistar rats were randomly allocated to four treatment groups. Group I) Control, Group II) Copper sulfate (200 mg/kg bw were appl...

Tepe Sagzabad, a site situated on the Qazvin Plain of north-central Iran, was excavated from 1970 to 1998 by the Institute ofArchaeology of Tehran University. Recent excavations by H. Tala’i (1997-1999) yielded some metal artifacts dating to theEarly Iron Age. Ten of these copper-based samples were investigated using inductively coupled plasma optical emissionspectroscopy (ICP-OES), scanning el...

in this work, we report synthesis and characterization of copper nanoparticles in polymer matrix by wet-chemical reduction method using ascorbic acid as reducing agent, copper (ii) sulfate as metal precursor and polyvinylpyrrolidone k-30 (pvp k-30) as surfactant agent. the reaction was carried out in a high-speed stirring mixture at room temperature under nitrogen atmosphere. characterization o...
