In this paper, a rapid and room temperature electrochemical method is introduced in preparationof Ni doped iron oxide nanoparticles (Ni-IONs) grafted with ethylenediaminetetraacetic acid (EDTA)and polyvinyl alcohol (PVA). EDTA/Ni-IONs and PVA/Ni-IONs samples were prepared through baseelectro-generation on the cathode surface from aqueous solution of iron(II) chloride, iron(III...

We evaluated the use of ion-exclusion chromatographic systems for analyzing the behavior of inorganic ions (e.g., bicarbonate, sulfate, chloride, nitrate, phosphate, dissolved silicate, sodium, ammonium, potassium, magnesium, and calcium ions) in a suburban river located in Jakarta, Indonesia. Carbonate, phosphate, and silicate ion concentrations were determined using ion-exclusion chromatograp...

Silver nitrate and aminoethoxyvinylglycine (AVG) are often used to inhibit perception and biosynthesis, respectively, of the phytohormone ethylene. In the course of exploring the genetic basis of the extensive interactions between ethylene and auxin, we compared the effects of silver nitrate (AgNO(3)) and AVG on auxin responsiveness. We found that although AgNO(3) dramatically decreased root in...

In contrast to animal cells, plants use nitrate as a major source of nitrogen. Following the uptake of nitrate, this major macronutrient is fed into the vasculature for long-distance transport. The Arabidopsis thaliana shoot expresses the anion channel SLOW ANION CHANNEL1 (SLAC1) and its homolog SLAC1 HOMOLOGOUS3 (SLAH3), which prefer nitrate as substrate but cannot exclude chloride ions. By co...

What is the difference between argentaffin and argyrophilic reactions? Both terms relate to the formation of colloidal metallic silver (latin argentum, Greek argyros) (1), which may range in color from yellow through brown to black depending on particle size and density, in specific structural components of tissues. the metal is formed at sites of reduction of silver ions derived from a stainin...

Nitrate Ion-Separation The underlying prerequisite for materials design to achieve on-target separation of low nucleophilic nitrate ions has been unclear. By fabricating cation-ordered layered double hydroxides (LDHs) via topochemical reaction, in article number 2201484, Tomohito Sudare, Katsuya Teshima, and colleagues demonstrate that the hexagonal arrangement effectively facilitates a stable ...
