Silver (Ag) is highly toxic to aquatic organisms, including algae, invertebrate animals, and fish, but little information exists on Ag rhizotoxicity in higher plants. In two solution culture experiments with approximately 1,000 microM Ca(NO3)2 and 5 microM H3BO3 (pH 5.4), 20 to 80% of added Ag (< or =2 microM) was lost from solution within approximately 30 min, with a further decrease after 48 ...

The promotion of Ag–ZSM-5 by cerium for the selective catalytic reduction (SCR) of NO with methane in the presence of an excess of oxygen was studied in this work. Ce–Ag–ZSM-5 catalyzes the CH4-SCR of NOx over the temperature range of 450–600◦C. Rate measurements of NO reduction to N2 under SCR conditions and of the competing CH4 oxidation by O2 (CH4 combustion) show that incorporation of a sma...

We have reported that a novel tumor-associated antigen (Ag), 22-1-1, was expressed in cancer cells derived mainly from the uterus and ovary [K. Sonoda et al., Cancer (Phila.), 77: 1501-1509, 1996]. The 22-1-1 Ag existed not only in adenocarcinomas but also in squamous cell carcinomas in the uterine cervix. Here, a relationship between tumor progression and invasion and 22-1-1 Ag expression was ...

The conventional anode for organic photovoltaics (OPVs), indium tin oxide (ITO), is expensive and brittle, and thus is not suitable for use in roll-to-roll manufacturing of OPVs. In this study, fully solution-processed polymer bulk heterojunction (BHJ) solar cells with anodes made from silver nanowires (Ag NWs) have been successfully fabricated with a configuration of Ag NWs/poly(3,4-ethylenedi...
