From colloidal dispersions to colloidal pastesthrough solid–liquid separation processes [PDF]
, 2005 Solid–liquid separation is an operation that starts with a dispersion of solid particles in a liquid and removes some of the liquid from the particles, producing a concentrated solid paste and a clean liquid phase.

Multiresidue Determination of Pesticides in Lanolin Using Matrix Solid-Phase Dispersion [PDF]
Journal of AOAC INTERNATIONAL, 2010 Abstract An efficient, fast, and accurate matrix solid-phase dispersion sample cleanup procedure was developed specifically for the determination of pesticide residues in lanolin. The scope of the method for organophosphorus, organochlorine, and pyrethroid insecticides is the same as that of official methods from various pharmacopeias ...

Coupling of elasticity to capillarity in soft aerated materials [PDF]
, 2013 We study the elastic properties of soft solids containing air bubbles. Contrary to standard porous materials, the softness of the matrix allows for a coupling of the matrix elasticity to surface tension forces brought in by the bubbles.

Nickel hydroxide nanoflower–based dispersive solid-phase extraction of copper from water matrix
Environmental Monitoring and Assessment, 2022 In this work, a dispersive solid-phase extraction method based on Ni(OH)2 nanoflowers (Ni(OH)2-NFs-DSPE) was developed to separate and preconcentrate copper ions from tap water samples for determination by flame atomic absorption spectrometry (FAAS). Ni(OH)2-NFs was synthesized using a homogeneous precipitation technique and used as sorbent for copper ...

Pion-pair formation and the pion dispersion relation in a hot pion gas [PDF]
, 1996 The possibility of pion--pair formation in a hot pion gas, based on the bosonic gap equation, is pointed out and discussed in detail. The critical temperature for condensation of pion pairs (Evans--Rashid transition) is determined as a function of the ...
