Aquatic Respiration Rate Measurements at Low Oxygen Concentrations

Despite its huge ecological importance, microbial oxygen respiration in pelagic waters is little studied, primarily due to methodological difficulties. Respiration measurements are challenging because of the required high resolution of oxygen concentration measurements. Recent improvements in oxygen sensing techniques bear great potential to overcome these limitations. Here we compare 3 differe...

Photoemission measurements of Ultrathin SiO2 film at low take-off angles

The surface and interfacial analysis of silicon oxide film on silicon substrate is particularly crucial in the nano-electronic devices. For this purpose, series of experiments have been demonstrated to grow oxide film on Si (111) substrate. Then these films have been used to study the structure of the film by using X-ray photo emission spectroscopy (XPS) technique. The obtained results indicate...

Aquatic nitrogen transformations at low oxygen concentrations.

Nitrite and nitrous oxide made up 40% of the hypolimnetic dissolved inorganic nitrogen in mesotrophic Lake Rotoiti, New Zealand, prior to hypolimnetic anoxia. Up to 120 mg of N m-3 as nitrite and 20 mg of N m-3 as nitrous oxide accumulated, whereas dissolved-oxygen concentrations remained between 1.0 and 0.2 g m-3 and were totally consumed when the hypolimnion became completely anoxic. Assays o...

Electrophoretic mobility of silica particles in a mixture of toluene and ethanol at different particle concentrations.

In this paper we present measurements of the electrophoretic mobility of colloidal particles by using heterodyne detection of light scattering. The measurements have been made up to concentrations of 5.4% silica nanoparticles, with a diameter on the order of 80 nm, in a mixture of 70% toluene and 30% ethanol. To make possible the measurements at these concentrations, the liquid mixture is chose...
