Abirami, A. L. Alagu published the artcileSynthesis and application of porous oil-sorbent microspheres: Characterization, retention capacity and sorption kinetics, COA of Formula: C16H30O2, the main research area is oil spill water pollution treatment polymer sorbent microsphere.

The article focuses on the study of oil spill cleanup in an aquatic media by comparing the oil sorption capacities of three polymeric sorbents. Styrene – dodecyl methacrylate – DVB with toluene as porogen (P3) showed a highest removal ability of 5 times its weight However, key aspect of this research is associated with the retention capacities of the sorbents. The loss in weight measured over time was found to be numerically insignificant for all the three sorbents. Water contact angle for the sorbents i.e., P1, P2, P3 were found to be 113.3°, 107.2° and 97.5° resp. SEM results confirmed the entrapment of oil between the polymer mols. thereby confirming the phenomenon of sorption. The sorption kinetics of oil over the sorbent surface was followed the pseudo-second order model. The prepared sorbents can be successfully employed for the recovery of oil spills from water sources.

Zhang, Rui published the artcileThermoresponsive hydrophobic copolymer grafted on agar microspheres for all-aqueous bioseparations, Computed Properties of 142-90-5, the main research area is agar microsphere thermoresponsive hydrophobic copolymer graft; N-isopropylacrylamide; agar microspheres; bioseparations; lauryl methacrylate; thermoresponsive polymers.

Agar microspheres were prepared by water-oil emulsification and cross-linked under alk. condition. The thermoresponsive hydrophobic copolymer, poly(N-isopropylacrylamide-co-lauryl methacrylate-co-acrylamide), was grafted on the agar microspheres via atom transfer radical polymerization The agar microspheres grafted with copolymers were characterized by light microphotog., elemental anal., Fourier transform IR spectroscopy, SEM, and XPS. The chain lengths and hydrophobic monomer ratio of the grafting linear polymer had significant effects on the hydrophobicity and adsorption capacity of agar microspheres at different temperatures The thermoresponsive microspheres were used for separation of proteins and showed binding and release behavior by change of temperatures without change in mobile phase composition Thus, we suggest thermoresponsive agar microspheres as an alternative separation media for all-aqueous biosepns.

Yoon, Seung Kyun published the artcileDevelopment of blood compatible composite using MPC copolymer and polyolefin for Non-PVC blood bag application, HPLC of Formula: 142-90-5, the main research area is blood bag compatible composite MPC copolymer polyolefin.

Polyolefin is a good candidate for a blood bag material alternative to the poly (vinyl chloride) (PVC) blood bag that contains di-2-ethylhexyl phthalate (DEHP). However, polyolefin readily adsorbs some plasma proteins and platelets. To prevent these undesired adsorption, 2-methacryloyloxyethyl phosphorylcholine (MPC) – hydroxyethyl methacrylate (HEMA) – lauryl methacrylate (LMA) copolymers with varying monomer ratios were synthesized and used as blended material for additives to reduce platelet adsorption. Platelet adsorptive properties were reduced by blending MPC copolymers with polyolefin and confirmed by the platelet adhesion test and the activated partial thromboplastin time (APTT) test.

Liu, Guiju published the artcileRole of refractive index in highly efficient laminated luminescent solar concentrators, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is laminated luminescent solar concentrator refractive index.

As a large-area solar radiation collector, luminescent solar concentrators (LSCs) can be used as power generation units in semitransparent solar windows, modernized agricultural greenhouses and building facades. However, the external optical efficiency and long-term stability of the LSCs limit their practical applications due to the sensitivity of the emitters to the light and environmental conditions. Here, we used the concept of “”laminated glass”” to prepare LSCs, which consist of two waveguide layers and the quantum dots (QDs)/polymer interlayer, and we tune the refractive index of the different parts of the system to improve the external optical efficiency and stability of the LSCs, simultaneously. The waveguide layer can be glass, quartz, polymethyl methacrylate (PMMA) and other transparent materials. The CdSe/CdS core/shell QDs were used as fluorophores to prepare the interlayer of the LSCs. The external optical efficiency of the laminated LSCs is associated with the refractive index of the three layers: the closer the refractive index, the higher the ηopt. The highest external optical efficiency of 3.4% has been achieved for the laminated PMMA/QDs-polymer/PMMA LSCs, which improved ~92% compared to the single-layered CdSe/CdS based LSCs. To the best of our knowledge, this is the highest efficiency for the LSCs based on CdSe/CdS QDs. These results pave the way to realize high efficiency laminated windows as power generation units by suitably tuning the structure of the LSC, and provide the theor. guidance for the LSCs utilized in building integrated photovoltaics.

Dilek, Aycan published the artcileThe Use of Poly(dodecyl methacrylate-co-N-isopropylacrylamide) Gel for the Separation of Limonene + Linalool Mixture, Related Products of esters-buliding-blocks, the main research area is dodecylmethacrylate isopropylacrylamide gel separation limonene linalool mixture.

Poly(dodecyl methacrylate-co-N-isopropylacrylamide) gels were prepared with and without a pore former (PEG) in ethanol at 70°C by free radical crosslinking polymerization method. These gels were used to sep. limonene + linalool mixtures with different fractions. The selectivity values were higher than 1 for each gel synthesized with PEG and without PEG. In equilibrium, selectivity values of gels synthesized without PEG in 90/10, 80/20, and 70/30 limonene + linalool binary mixtures were calculated as 1.1, 1.9, and 2.1, resp. The corresponding gels synthesized using PEG have selectivity values as 1.3, 1.9, and 2.2. Despite slightly effect of pore former on selectivity, it has a relatively significant effect in time regions before arriving equilibrium, giving the idea of selecting optimum time region to sep. binary mixtures Solubility parameter of the gel was predicted by group contribution methods to determine the relationship between selectivity and solubility parameter difference of binary combinations of limonene, linalool and gel. Solubility parameter difference calculated from Hoy method showed that the value of each solubility parameter contribution for gel-linalool binary was the lowest with the values of 0.02, 1.7, and 4.8 for disperse, polar and H-bonding contributions, resp. verifying the selectivity of the gels for linalool. The gel synthesized using PEG shows a swelling value change for temperatures higher than 40°C in the direction of decreasing but the gel synthesized without PEG has approx. constant equilibrium swelling value (ESV). This result indicates that the use of a pore former may be an important parameter in the recovery process of the extracted components after the separation procedure.

Kovylin, R. S. published the artcileOne-step photolytic synthesis of hydrophobic porous polymer materials by the copolymerization of the dimethacrylate-alkyl methacrylate system in the presence of methanol, Application In Synthesis of 142-90-5, the main research area is methacrylate system hydrophobic porous polymer material methanol photopolymerization.

Hydrophobic porous polymer materials were synthesized by one-step visible light polymerization from compositions consisting of phthalate-containing oligoester di(meth)acrylate MDP-2, methanol, and alkyl methacrylate (Bu methacrylate, ethylhexyl methacrylate, iso-decyl methacrylate, lauryl methacrylate, and stearyl methacrylate) compositions The highest hydrophobization effect is observed for stearyl methacrylate. The maximum MDP-2 block photopolymerization rate is by 16-50 times higher than that of alkyl methacrylates. The sp. surface areas of the synthesized porous polymers reach 4.2 m2 g-1, and the pore size ranges from 5.5 to 17 μm. The addition of stearyl methacrylate to the composition leads to the pore size distribution narrowing. The principal possibility of using these photopolymerizable compositions as stationary phases for liquid chromatog. is shown.

Zhao, Yi published the artcileDesign and characterization of oil-in-water nanoemulsion for enhanced oil recovery stabilized by amphiphilic copolymer, nonionic surfactant, and LAPONITE RD, Related Products of esters-buliding-blocks, the main research area is oil water nanoemulsion amphiphilic copolymer nonionic surfactant LAPONITE.

The application of nanotechnol. in the oil and gas industry has attracted widespread attention in recent years. This study aims to develop a nanoemulsion (NE) for use in enhanced oil recovery (EOR). The NE stabilized by anion amphiphilic copolymer, nonionic surfactant (Brij30) and modified LAPONITE RD was prepared by the phase inversion composition (PIC) method. The appearance of the emulsion is translucent and the average particle size is less than 60 nm. The micromorphol. and interfacial tension (IFT) are examined using transmission electron microscopy (TEM) and a spinning drop IFT meter, resp. The NE possesses good stability evaluated by conductivity and particle size tests. The absolute value of the zeta potential of NE increases when modified LAPONITE RD is added. In a core flooding experiment with an artificial sandstone core, the NE flooding increased oil recovery by 23.53% compared to water flooding.

Shabnam, Rukhsana published the artcileCumulative effect of hydrophobic PLMA and surface epoxide groups in composite polymer particles on adsorption behavior of congo red and direct red-75, Related Products of esters-buliding-blocks, the main research area is composite polymer particle hydrophobic PLMA epoxide dye adsorption.

Industrial applications of hydrophobic materials are numerous, particularly as adsorption beads to remove organic pollutants. In this research combined effect of hydrophobicity and reactive epoxide group on the adsorption behavior of dye mols. by composite polymer particles was investigated. Lauryl methacrylate (LMA) a poor water soluble long chain vinyl monomer is com. available. Polystyrene/poly(LMA-divinyl benzene) or PS/P(LMA-DVB) composite seed particles were first prepared by slightly modified activated swelling of micron-sized PS seed particles utilizing either water or water-ethanol dispersion medium. The influence of poly(vinyl alc.) (PVA) as steric stabilizer on the size and size distribution was evaluated. The poor solubility of LMA in the continuous phase hindered the homogeneous swelling of PS particles even in the presence of ethanol (5% weight/weight) and resulted in fairly polydispersed PS/P(LMA-DVB) composite seed particles. The composite seed particles were then functionalized with epoxide group by seeded polymerization of glycidyl methacrylate (GMA) to produce PS/P(LMA-DVB)/PGMA composite polymer particles. The epoxide functionalized PS/P(LMA-DVB)/PGMA composite polymer particles were used to adsorb two kinds of azo dyes, congo red (CR) and direct red-75 (DR-75). The effects of initial dye concentration at 303 and 323 K on adsorption behavior were investigated and the adsorption was explained by adsorption isotherms. Temperature dependent adsorption measurements were also carried out at identical initial dye concentration The adsorption results showed that inclusion of reactive epoxide group on/near the surface of hydrophobic PS/P(LMA-DVB) composite seed particles improved the adsorption capacity of dye mols.

Han, Linglin published the artcileMussel-inspired, robust and self-healing nanocomposite hydrogels: Effective reusable absorbents for removal both anionic and cationic dyes, Synthetic Route of 142-90-5, the main research area is self healing nanocomposite hydrogel adsorbent dye removal.

Polydopamine (PDA) composited LAPONITE cross-linked hydrophobically associated (PLHA) hydrogels were facilely constructed by in situ polymerization The PLHA hydrogel exerted improved mech. properties and excellent stability with an addnl. crosslinking agent LAPONITE, which guaranteed the hydrogel could be utilized for long-time and reusable application. Notably, the self-healing property of PLHA gels could be achieved easily by the hereinafter three factors: hydrophobic association, LAPONITE and PDA. Compared with the pristine hydrophobic associated (HA) gel, excellent dye adsorption capacity toward both anionic and cationic dyes came out in PLHA gels owing to the neg. charges on LAPONITE and abundant functional groups on PDA nanoparticles such as amine groups, catechol groups and aromatic moieties. The PLHA gels could bind organic dyes via various ways, including coordination, electrostatic interaction, hydrogen bonding or π-π stacking interaction. Compared with the reported works, our proposed method provided the opportunity to prepare a novel robust, self-healing phys. dual cross-linked hydrogels, which have the potential to be applied in tissue engineering and the reusable adsorbents of organic colorants.

Jaoued-Grayaa, Najeh published the artcileDesign of molecularly imprinted polymer materials relying on hydrophobic interactions, Formula: C16H30O2, the main research area is acrylic molecularly imprinted polymer crosslinking hydrophobic silica adsorption kinetics.

The design of molecularly imprinted polymers (MIPs) for the specific binding of hydrophobic mols. (mitotane) was investigated by considering monomers and crosslinking agents with variable hydrophobic character, Me methacrylate, Bu methacrylate and lauryl methacrylate as functional monomers, and ethylene glycol dimethacrylate and 1,6-hexanediol dimethacrylate as crosslinking agents. MIPs were bound to a porous silica support by means of a radical transfer reaction with grafted 3-mercaptopropyl groups. Equilibrium adsorption isotherms to molecularly imprinted and non-imprinted materials were modeled with the Volmer and Langmuir-Volmer isotherms, giving the thermodn. parameters of adsorption. The most hydrophobic monomer provided the highest selective adsorption although strong non-selective adsorption and the intrinsic softness of poly(lauryl methacrylate) is detrimental to selectivity. Adsorption was exothermic with a predominant enthalpic contribution. Adsorption kinetics were fast due to the high accessibility of mol. imprints on the surface of the thin MIP layer coating the porous silica support.
