Hydrophilic hypercrosslinked polymeric sorbents for the solid-phase extraction of polar contaminants from water [PDF]

open access: yes, 2010
Three new hypercrosslinked polymers with hydrophilic character arising from hydroxyl moieties in their skeletons have been prepared in microsphere format and applied to the off-line solid-phase extraction (SPE) of polar compounds from water samples.

Reduction of the formaldehyde content in leathers treated with formaldehyde resins by means of plant polyphenols [PDF]

open access: yes, 2017
Formaldehyde has applications in many industrial processes, including synthesis of resins and syntans to be used in the retanning process of leather. When resins are employed, they can hydrolyse, releasing formaldehyde.

Coarse graining of slow variables in dynamic simulations of soft matter [PDF]

open access: yes, 2007
A new Brownian dynamics model is presented to describe the coarse grain dynamics of particles with long-lived memory. Instead of solving a set of generalized Langevin equations we introduce a set of variables describing the slowly fluctuating ...

The effects of alkyd/melamine resin ratio and curing temperature on the properties of the coatings [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
Synthetic resins are used as binders in protective coatings. An alkyd/melamine resin mixture is the usual composition for the preparation of a coating called “baking enamel” cured through functional groups of resins.

Adsorption of phenol/tyrosol from aqueous solutions on macro-reticular aromatic and macro-porous polystyrene cross-linked with divinylbenzene polymeric resins [PDF]

open access: yes, 2011
The current work aims at separating by adsorption of low-molecular-weight organic compounds in a nanofiltration concentrate of the olive mill wastewaters. The experimental investigations on adsorption of phenol/tyrosol in single and binary systems were

Adsorption of heavy metal ions and azo dyes by crosslinked nanochelating resins based on poly(methylmethacrylate-co-maleic anhydride)

open access: yeseXPRESS Polymer Letters, 2014
Chelating resins are suitable materials for the removal of heavy metals in water treatments. A copolymer, Poly(MMA-co-MA), was synthesized by radical polymerization of maleic anhydride (MA) and methyl methacrylate (MMA), characterized and transformed ...

Acylsulfonamide safety-catch linker : promise and limitations for solid-phase oligosaccharide synthesis [PDF]

open access: yes, 2012
Safety-catch linkers are useful for solid-phase oligosaccharide synthesis as they are orthogonal to many common protective groups. A new acylsulfonamide safety-catch linker was designed, synthesized and employed during glycosylations using an automated ...
