Abstract With the widespread use of batteries, their increased performance is growing in importance. One avenue for this enhancement ion diffusion, particularly solid‐state electrolytes, different ions such as lithium (Li + ) and magnesium (Mg 2+ ). Unraveling origin better cation diffusion confined ionic liquids (ILs) a polymer matrix (ionogels) compared to that IL itself. Ionic conductivity measured by electrochemical impedance spectroscopy ionogels (7.0 mS cm −1 at 30 °C) very close...

Microparticles decorated with metal–organic frameworks exhibited a unique flow-dependent separation selectivity (FDSS) effect for the isocratic of small molecules.

The immobilization of caffeic acid (CA) on a polypropylene (PP) film was successfully performed through the covalent binding caffeoyl chloride modified polymeric surface PP films grafted with hydroxyethyl methacrylate as monomer (PP-g-HEMA). different reaction steps were monitored by FT-IR spectroscopy. synthesized characterized Folin−Ciocalteu method measuring available phenolic groups equivalents linked to surface. antioxidant efficiency polymers evaluated typical spectrophometric methods,...

Within recent years there has been an increase in research focused on the design and application of organic polymer monoliths all areas separation science. This is largely driven by theoretical practical benefits that these materials should be able to provide, particularly terms improved biocompatibility high permeability. review summarises new developments this field with a focus approaches synthesis polymeric monolithic for analytical includes use alternative synthetic methodologies such...

In the last years, macroporous monolithic materials have been introduced as a new and useful generation of polymers used in different fields. These may be prepared simple way from homogenous mixture into mold contain large interconnected pores or channels allowing for high flow rates at moderate pressures. Due to their porous characteristics, they could processes, such stationary phases types chromatography, high-throughput bioreactors microfluidic chip applications. This review reports...

Oil-in-water (‘inverse’) High Internal Phase Emulsions (HIPEs) have been prepared using an amphiphilic macro-RAFT agent with toluene as the internal dispersed phase (∼80 vol%) and aqueous monomer solution continuous phase.

Abstract Natural deep eutectic solvents have been used as an alternative to organic for the extraction of plants metabolites, allowing compounds different polarities, while being inexpensive, non‐toxic, and easy prepare. This work presents comparison chromatographic profiles by high‐performance liquid chromatography with diode‐array detection obtained from Byrsonima intermedia (Malpighiaceae) using five choline chloride‐based natural solvents, in addition most traditional methanol/water 7:3...

Polymerized High Internal Phase Emulsions (PolyHIPEs) were prepared using emulsion-templating, stabilized by an amphiphilic diblock copolymer reversible addition fragmentation chain transfer (RAFT) polymerization. The consisted of a hydrophilic poly(ethylene glycol) methyl ether acrylate (PEO MA, average Mn 480) segment and hydrophobic styrene segment, with trithiocarbonate end-group. These copolymers the sole emulsifiers used in stabilizing "inverse" (oil-in-water) high internal phase...

A new effect was discovered which allows changes of selectivity by variation the mobile phase flow rate.

Rigid aligned polymers were prepared by directional freezing and photo-initiated cryopolymerisation tested as stationary phases in liquid chromatography.

The influence of the addition various non-ionic surfactants to poly(ethylene glycol) diacrylate-based monolith formulations was studied. Eight having different chemistries were chosen for this study. These Brij L4, Span 80, IGEPAL CO-520, Tergitol 15S9, 2,4,7,9-tetramethyl-5-decyne-4,7-diol ethoxylate, Tween 40, Triton X-405, and Tetronic 701. chemical structures these have a variety functional groups cover wide range molecular weights (360–3600 g/mol), viscosities (60–1500 cP),...

Almond trees are the most cultivated nut tree in world. The production of almonds generates large amounts by-products, much which goes unused. Herein, this study aimed to develop a green chemistry approach identify and extract potentially valuable compounds from almond by-products. Initially, screening was performed with 10 different Natural Deep Eutectic Solvents (NADESs). mixture lactic acid/glycerol, molar ratio 1:1 (1:50 plant material NADES (w/v) 20% v/v water) identified as best...

Polymer-based monolithic high-performance liquid chromatography (HPLC) columns are normally obtained by conventional free-radical polymerization. Despite being straightforward, this approach has serious limitations with respect to controlling the structural homogeneity of monolith. Herein, we explore a reversible addition–fragmentation chain transfer (RAFT) polymerization method for fabrication porous polymers well-defined morphology and surface chemistry in confined 200 μm internal diameter...
