A computerized Langmuir probe system [PDF]
, 2003 For low pressure plasmas it is important to record entire single or double Langmuir probe characteristics accurately. For plasmas with a depleted high energy tail, the accuracy of the recorded ion current plays a critical role in determining the electron

Removal of Copper (II) Ions from Polluted Water Using Modified Wheat Bran
Environmental and Climate Technologies, 2021 The discharge of wastewater containing heavy metals into waterbodies is a major environmental issue that can influence the quality of the water supply; therefore, it is important to remove the pollutants dangerous to living organisms.

Langmuir and Langmuir–Blodgett Films of Gold and Silver Nanoparticles
Langmuir, 2023 Recently the focus of the Langmuir-Blodgett technique as a method of choice to transfer monolayers from the air/water interface onto solid substrates in a controllable fashion has been shifting toward purely hydrophobic gold and silver nanoparticles.

Competitive adsorption of p-hydroxybenzoic acid and phenol on activated carbon : experimental study and modelling. [PDF]
, 2013 The competitive adsorption of phenol and p-hydroxybenzoic acid (4HBA) has been investigated on activated carbon (AC) for a wide range of concentrations under unbuffered conditions. The results show a preferential adsorption of 4HBA which can be explained

Landau damping of partially incoherent Langmuir waves
, 2002 It is shown that partial incoherence, in the form of stochastic phase noise, of a Langmuir wave in an unmagnetized plasma gives rise to a Landau-type damping. Starting from the Zakharov equations, which describe the nonlinear interaction between Langmuir

Generalization of the Langmuir–Blodgett laws for a nonzero potential gradient [PDF]
, 2015 The Langmuir–Blodgett laws for cylindrical and spherical diodes and the Child–Langmuir law for planar diodes repose on the assumption that the electric field at the emission surface is zero.

Interpreting Charles Lamb’s ‘Neat-Bound Books’
Studia Anglica Posnaniensia, 2019 In this paper we consider a much-quoted phrase published by the essayist Charles Lamb (1775–1834) in the London Magazine in 1822 about a desirable quality in books: that they should be ‘strong-backed and neat-bound’. We identify meanings of modifier neat
