Behavior of Langmuir Probes in Non-Equilibrium Plasmas [PDF]
Langmuir probes are diagnostic tools used to determine electron temperature, number density, and plasma potential. Irving Langmuir first used an electrostatic probe in the 1920s to find these characteristics in ionized gases.

Observations of Ion Density and Temperature around the International Space Station During two Geomagnetic Storms [PDF]
, 2018 The International Space Station (ISS) is a low Earth orbit research facility and host to an international crew. Geomagnetic storms cause changes in the Earth’s magnetic field and affect the ion density and temperature in the ionosphere which could pose a

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Bamboo charcoal–based extruded activated carbons were prepared via molding, pre‐oxidation, carbonization, and steam activation, with coal tar, phenolic resin, and their mixtures employed as binders based on practical availability and technical feasibility. This study focused on the regulatory effects of binders on the mechanical properties and

Langmuir probe measurements of double-layers in a pulsed discharge [PDF]
Langmuir probe measurements were carried out which confirm the occurrence of double-layers in an argon positive column. Pulsing the discharge current permitted probe measurements to be performed in the presence of the double-layer. Supplementary evidence,

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Four benzothiophenes, thianaphthene (BT‐1), 3‐bromothianaphthene (BT‐2), benzo[b]thiophene‐2‐carboxaldehyde (BT‐3), and benzo[b]thiophene‐2‐carbonitrile (BT‐4), were tested as mild steel corrosion inhibitors in 1‐M HCl. The compounds have the similar benzothiophene core but differ in the substituents bound to the ring.

Langmuir Probe Measurements of an Argon Plasma [PDF]
, 2014 In the field of thin-film research, there exists a novel method of film growth called Plasma Enhanced Chemical Vapor Deposition or PECVD. This technique utilizes the energetic electrons released from a plasma discharge to help catalyze chemical reactions

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...
