Copper–cobalt double metal cyanides as green catalysts for phosphoramidate synthesis
Communications Chemistry, 2023 Phosphoramidates are common and widespread backbones of a great variety of fine chemicals, pharmaceuticals, additives and natural products. Conventional approaches to their synthesis make use of toxic chlorinated reagents and intermediates, which are ...

Gas adsorption in active carbons and the slit-pore model 1 : pure gas adsorption [PDF]
, 2005 We describe procedures based on the polydisperse independent ideal slit-pore model, Monte Carlo simulation and density functional theory (a 'slab-DFT') for predicting gas adsorption and adsorption heats in active carbons.A novel feature of this work is ...

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

Adsorption in hemodialysis [PDF]
Kidney International, 2000 The use of sorbents in different blood purification techniques is reviewed. The sorbents used in these therapies are divided into two groups: (1) Adsorption occurs fundamentally because of the hydrophobic properties of the sorbents. In this group, the sorbents used in different dialysis techniques are charcoal and nonionic macroporous resins.

Polymer Journal, 1991 We discuss some recent results about the scaling approach to polymer adsorption. The various concentration regimes are discussed, as well as the concentration profile in the plateau range. These are compared with experimental results. We briefly discuss surface imperfections such as regular or fractal roughness and chemical impurities.
