High-resolution inductive measurement of electrical resistivity and density of electromagnetically levitated liquid metal droplets.

A new device for the inductive measurement of electrical resistivity and density of liquid metals and semiconductors is presented. It is integrated in two electromagnetic levitation facilities operating under microgravity. As a result, the completely noninvasive handling and measuring of the metallic melt enables the extension of the accessible sample temperature range far into the undercooled liquid state below the melting point. The microgravity environment permits the undisturbed joining of the containerless inductive sample handling method by the electromagnetic levitation with the inductive sample measurement technique. The following sections explain in detail the basic principles and the technical realization of the whole measurement apparatus and present experimental data showing its high resolution resulting from the combination of microgravity, electromagnetic levitation, and inductive measurement technique.

Application of an online ion-chromatography-based instrument for gradient flux measurements of speciated nitrogen and sulfur

Abstract. The dry component of total nitrogen and sulfur atmospheric deposition remains uncertain. The lack of measurements of sufficient chemical speciation and temporal extent make it difficult to develop accurate mass budgets and sufficient process level detail is not available to improve current air–surface exchange models. Over the past decade, significant advances have been made in the development of continuous air sampling measurement techniques, resulting with instruments of sufficient sensitivity and temporal resolution to directly quantify air–surface exchange of nitrogen and sulfur compounds. However, their applicability is generally restricted to only one or a few of the compounds within the deposition budget. Here, the performance of the Monitor for AeRosols and GAses in ambient air (MARGA 2S), a commercially available online ion-chromatography-based analyzer is characterized for the first time as applied for air–surface exchange measurements of HNO3, NH3, NH4+, NO3−, SO2 and SO42−. Analytical accuracy and precision are assessed under field conditions. Chemical concentrations gradient precision are determined at the same sampling site. Flux uncertainty measured by the aerodynamic gradient method is determined for a representative 3-week period in fall 2012 over a grass field. Analytical precision and chemical concentration gradient precision were found to compare favorably in comparison to previous studies. During the 3-week period, percentages of hourly chemical concentration gradients greater than the corresponding chemical concentration gradient detection limit were 86, 42, 82, 73, 74 and 69 % for NH3, NH4+, HNO3, NO3−, SO2 and SO42−, respectively. As expected, percentages were lowest for aerosol species, owing to their relatively low deposition velocities and correspondingly smaller gradients relative to gas phase species. Relative hourly median flux uncertainties were 31, 121, 42, 43, 67 and 56 % for NH3, NH4+, HNO3, NO3−, SO2 and SO42−, respectively. Flux uncertainty is dominated by uncertainty in the chemical concentrations gradients during the day but uncertainty in the chemical concentration gradients and transfer velocity are of the same order at night. Results show the instrument is sufficiently precise for flux gradient applications.

Identification of dopaminergic neurons of the substantia nigra pars compacta as a target of manganese accumulation.

Manganese serves as a cofactor to a variety of proteins necessary for proper bodily development and function. However, an overabundance of Mn in the brain can result in manganism, a neurological condition resembling Parkinson's disease (PD). Bulk sample measurement techniques have identified the globus pallidus and thalamus as targets of Mn accumulation in the brain, however smaller structures/cells cannot be measured. Here, X-ray fluorescence microscopy determined the metal content and distribution in the substantia nigra (SN) of the rodent brain. In vivo retrograde labeling of dopaminergic cells (via FluoroGold™) of the SN pars compacta (SNc) subsequently allowed for XRF imaging of dopaminergic cells in situ at subcellular resolution. Chronic Mn exposure resulted in a significant Mn increase in both the SN pars reticulata (>163%) and the SNc (>170%) as compared to control; no other metal concentrations were significantly changed. Subcellular imaging of dopaminergic cells demonstrated that Mn is located adjacent to the nucleus. Measured intracellular manganese concentrations range between 40-200 μM; concentrations as low as 100 μM have been observed to cause cell death in cell cultures. Direct observation of Mn accumulation in the SNc could establish a biological basis for movement disorders associated with manganism, specifically Mn caused insult to the SNc. Accumulation of Mn in dopaminergic cells of the SNc may help clarify the relationship between Mn and the loss of motor skills associated with manganism.

Effect of folic acid decorated magnetic fluorescent nanoparticles on the sedimentation of starch molecules

Ferrite–folic acid (FA) nanohybrids were synthesized and characterized by various analytical tools like Fourier transform infrared spectroscopy, UV–Visible spectroscopy, fluorescence spectroscopy, field emission scanning electron microscopy, X-ray diffraction analysis and vibrating sample measurement techniques. After the nanohybrid formation, both the crystallinity and the magnetization values of ferrite were disturbed due to the surface functionalization of ferrite by FA. The role of nanohybrid on the structure–property relationship of starch, particularly the sedimentation of starch under three different pHs, was evaluated. Again the magnetization value of Fe3O4–FA/starch nanocomposite system was reduced due to the encapsulation effect. The sedimentation velocity of starch under the influence of nanohybrid was enhanced in the acidic medium.

Differential Sampling Measurement of a 7 V RMS Sine Wave With a Programmable Josephson Voltage Standard

A 10 V programmable Josephson voltage standard has enabled sine waves with voltages up to 7 V RMS to be accurately measured with a differential sampling measurement technique. Expanding the voltage range for this technique enables the direct calibration of the low-frequency ranges of commercial calibrators in the ac voltage mode. This paper reviews the practically achievable performance and challenges of the differential sampling measurement technique that arise when measuring RMS voltages greater than a few volts. A relative Type A uncertainty of 4 parts in $10^{7}$ was achieved with the technique when measuring a 7 V RMS sine wave generated by a calibrator at 62.5 Hz.

Time-Resolved Switching Characteristic in Magnetic Tunnel Junction with Spin Transfer Torque Write Scheme

The time-resolved switching characteristics of 100×200 nm2 size CoFeB/MgO/CoFeB-based magnetic tunnel junction (MTJ) are investigated by using the 20 GHz sampling measurement technique. We focused on the physical quantities of the time-resolved characteristics such as incubation time tA, transit time tB, and the standard deviations σV's of the period of the switching waveform. Furthermore, the dependencies of tA and tB on the applied pulse waveforms are analyzed. We found tA exponentially decreases as the applied voltage to MTJ increases, while tB remains less than two nano seconds regardless of the applied voltage. Furthermore, it is observed that the standard deviations of the waveform during tA is larger than that of the other periods. Finally, we discuss the switching characteristics with proposed toy model based on spin transfer torque (STT) phenomena.
