DC Langmuir Probe for Measurement of Space Plasma: A Brief Review [PDF]
Journal of Astronomy and Space Sciences, 2015 Herein, we discuss the in situ measurement of the electron temperature in the ionosphere/plasmasphere by means of DC Langmuir probes. Major instruments which have been reported are a conventional DC Langmuir probe, whose probe voltage is swept; a ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Effects of Ingested vs. Injected Propellant on Radio-Frequency Discharge Plasma Properties
Frontiers in Physics, 2019 Radio-frequency (RF) ion thrusters are characterized in vacuum test facilities differentiated by pumping speed and thus subject to varying levels of neutral propellant ingestion that affect plasma plume properties and artificially raise the pressure of ...

ELECTRON TEMPERATURES IN ORION A
The Astrophysical Journal, 2015 We measured the hydrogen, helium, and carbon 106α radio recombination lines (RRLs), three different β and γ lines, and radio continuum at 4' east, west, and south of the peak of the H ii region NGC 1976 (Messier 42, Orion A) with the NRAO Green Bank Telescope at 5 GHz.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Study on the ageing of insulators based on the surface charge accumulation process
The Journal of Engineering, 2019 In order to study the transient motion of the space charge around the air tower insulator and the charge distribution of the insulator, a two-dimensional mixed numerical model of the insulator string based on chemical reaction is proposed. The simulation

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Spatial Temperature Profile in a Magnetised Capacitively Coupled Discharge
Walailak Journal of Science and Technology, 2018 A floating emissive probe has been used to obtain the spatial electron temperature (Te) profile in a 13.56 MHz parallel plate capacitive coupled plasma. The effect of an external transverse magnetic field and pressure on the electron temperature profile ...

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
