Ruiperez, Violeta published the artcileContinuous malolactic fermentation of red wine in a reactor using silica-alginate encapsulated Oenococcus oeni, Product Details of C17H34O2, the main research area is Oenococcus oeni encapsulation red wine malolactic fermentation reactor.

Malolactic fermentation (MLF) is a challenging and time-consuming step in the winemaking process. The effects of climate change are making the intrinsic conditions in red wine more challenging for the growth of lactic acid bacteria through interfering with a prompt and effective MLF. However, this is a necessary process in red wine production that contributes to high quality of wine demanded by consumers. Previous studies in our group reported a highly efficient MLF of red wine by using encapsulated Oenococcus oeni. Here, we designed a bench-scale packed-bed reactor using encapsulated bacteria to facilitate and speed up this process. The time to complete MLF was reduced as the concentration of biocapsules increased. The system exhibited operational stability and efficiency in sequential batches of wine recirculated through the column. Furthermore, an efficient continuous MLF was achieved using the packed-bed reactor. In general, a slight reduction in the concentration of some volatile organic compounds (VOCs) in the wines from the continuous system was observed as compared to those from the recirculated system.

Liu, Kunpeng published the artcileChemical bonding of biological valve leaflets with an aminated zwitterionic copolymer for long-term anticoagulation and improved anti-calcification, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is valve leaflet aminated zwitterionic copolymer chem bonding anticoagulation anticalcification.

Glutaraldehyde cross-linked pericardium (GLUT), mostly used in Bioprosthetic heart valves (BHVs) clin., still has problems of valve thrombus, cytotoxicity, and calcification. Although many new crosslinking approaches have been explored to obtain certain biol. achievements, their clin. applications are still some way off, which might be ascribed to the limitations of preservation and sterilization. In this study, a novel post-crosslinking of GLUT was developed using a zwitterionic copolymer. The copolymer imitating the mol. structure of phospholipids was composed of the copolymerization of 2-methacryloyloxyethyl phosphorylcholine (MPC), N-(3-Aminopropyl) methacrylamide hydrochloride (APMA), and Lauryl methacrylate (LMA). With the introduction of primary amines, the zwitterionic copolymer could be effectively utilized in the post-crosslinking of GLUT. Meanwhile, the anticoagulation properties of valve leaflets could be adjusted by combining aminated zwitterionic copolymers with different mol. weights The valve leaflets modified with aminated zwitterionic copolymer not only maintained original mech. property and structural integrity, but also significantly improved the long-term anti-coagulation and stability in vitro and ex vivo. The s.c. implantation confirmed that the modified leaflets possessed great resistance to calcification along with reduced inflammatory response. Besides, the modified leaflets could be further stored in glutaraldehyde solution (a storage formula for com. valves) and still retained great anti-coagulant and anti-calcification properties. The study demonstrated a better clin. potential of the modified leaflets via the post-crosslinking of glutaraldehyde treated leaflets with the aminated zwitterionic copolymer.

Zhang, Rui published the artcileA facile strategy toward hydrophobic-oleophilic 3D Fe foam for efficient oil-water separation, Safety of Dodecyl 2-methylacrylate, the main research area is iron foam dodecyl mercaptan coating separator wastewater treatment.

In this work, we present a hydrophobic-oleophilic Fe foam for oil-water separation Hydrophobic-oleophilic Fe foam was fabricated simply through dip-coating with n-dodecyl mercaptan. The morphol., chem. composition and water contact angle of the Fe foam were characterized. The Fe foam could absorb a variety of oils, such as diesel, toluene, xylene, cyclohexane, dodecyl methacrylate, crude oil, 1,2-dichloroethane, hexane and chloroform, these oils could be underwater or on water surface, and it exhibited excellent durability, verified by the high separation efficiency (more than 98.8% for a cyclohexane-water mixture) after reusing for 48 times. Furthermore, oil collection with the Fe foam could be controlled remotely using external magnetic field, and the Fe foam displayed high flux, good anti-corrosion and wear resistance. The simple and low-cost fabrication method enabled the Fe foam to be a promising candidate for large-scale oil-water separation and for remotely controllable water purification

Xu, Liyun published the artcileStable super-hydrophobic lauryl methacrylate film fabrication on the surface of cotton fabrics in plasma-enhanced chemical vapor deposition with different duty cycles, Formula: C16H30O2, the main research area is lauryl methacrylate cotton fabric film fabrication superhydrophobicity.

In this paper, stable super-hydrophobic lauryl methacrylate (LMA) film on the surface of cotton fabrics was fabricated by a simple process of pulsed plasma-enhanced chem. vapor deposition (PECVD) with different duty cycles. The influence of duty cycles on the surface structure and properties of cotton fabrics was analyzed after a series of measurements. The results showed that water contact angles (WCAs) of samples were inversely proportional to the duty cycle values and exhibited the highest WCA (162°) at a duty cycle of 2%. The optimized washing durability of samples was obtained under the treatment of duty cycle of 25% and the WCA could still reach 127° after 15 laundering cycles. The formation of a micro-nano-composite structure and evenness of film could be observed by at. force microscopy and SEM. Nevertheless, the sample, which was treated by plasma with a 25% duty cycle, had the best uniformity of film deposition. The results of attenuated total reflection Fourier transform IR spectroscopy and XPS illustrated that the LMA monomer was grafted and deposited on the surface of cotton fabrics successfully in covalent binding after PECVD treatment, and this was supposed to be the cause of the washing stability of the films. The results indicated that cotton fabrics modified with the proposed method can exhibit excellent super-hydrophobicity and washing durability, while the duty cycle was an appreciable effect factor in the modification.

Fernandes, Marta published the artcileBacterial cellulose and emulsified AESO biocomposites as an ecological alternative to leather, HPLC of Formula: 142-90-5, the main research area is bacterial cellulose emulsified acrylated epoxidized soybean oil hydrophobic composites; thermal mech property; acrylated epoxidized soybean oil; alternative leather; bacterial cellulose; biocomposite; emulsion; exhaustion.

This research investigated the development of bio-based composites comprising bacterial cellulose (BC), as obtained by static culture, and acrylated epoxidized soybean oil (AESO) as an alternative to leather. AESO was first emulsified; polyethylene glycol (PEG), polydimethylsiloxane (PDMS) and perfluorocarbon-based polymers were also added to the AESO emulsion, with the mixtures being diffused into the BC 3D nanofibrillar matrix by an exhaustion process. SEM and Fourier transform IR (FTIR) spectroscopy anal. demonstrated that the tested polymers penetrated well and uniformly into the bulk of the BC matrix. The obtained composites were hydrophobic and thermally stable up to 200°C. Regarding their mech. properties, the addition of different polymers lead to a decrease in the tensile strength and an increase in the elongation at break, overall presenting satisfactory performance as a potential alternative to leather.

Wan, Xizi published the artcileA Wetting-Enabled-Transfer (WET) Strategy for Precise Surface Patterning of Organohydrogels, Safety of Dodecyl 2-methylacrylate, the main research area is wetting enabled transfer WET strategy precise surface patterning organohydrogel; interfacial interactions; organohydrogels; surface patterning; wetting-enabled-transfer (WET).

The ability to manipulate water and oil phases in a designable manner is of great significance in widespread fields from art paintings to materials science. However, achieving precise and stable surface patterns for two immiscible phases of water and oil remains a challenge. Herein, a general wetting-enabled-transfer (WET) strategy is reported to construct discretionary shape-defined surface patterns of organohydrogels along with their monolithic formation either from flat to curved surfaces or from the microscale to the macroscale. Locally differentiated wettability induces hydrophilic monomers and hydrophobic monomers from an emulsion system onto the wettability-matching regions of the prepatterned substrates, subsequently forming corresponding hydrogel and organogel patterns on the organohydrogel surface after in situ photopolymerization The precision of the surface patterns can be controlled by optimizing the gel monomers, emulsion droplet size, and surface chem. composition of the prepatterned substrates. This finding may provide a feasible strategy for precisely patterning functional materials from two-immiscible-phase systems.

Sun, Yiqi published the artcileGrafting Lignin with Bioderived Polyacrylates for Low-Cost, Ductile, and Fully Biobased Poly(lactic acid) Composites, Formula: C16H30O2, the main research area is lignin bioderived polyacrylate graft toughening agent polylactic acid composite.

It has been always attractive to design low-cost, ductile, and fully biobased polylactic acid (PLA) composites based on industrial waste lignin for promoting its practical applications in the industry. Unfortunately, existing material strategies often lead to poor processability and low ductility because of weak interfaces between lignin and PLA. Herein, we report a fully biobased functionalized lignin (Lig-g-P(LMA-co-THFMA), or Mlignin) by chem. grafting two bioderived monomers, lauryl methacrylate (LMA), and tetrahydrofurfuryl methacrylate (THFMA) via free-radical polymerization Mlignin exhibits moderately lower melt viscosity and improved formability with PLA as compared with pristine lignin due to better interfacial combability. Because of improved interfacial adhesion, Mlignin is capable of uniformly dispersing within the PLA matrix in a submicron phase size, leading to a “”sea-island”” structure. As a result, the addition of 20 wt % Mlignin increases the ductility by 16 folds (from 12 to 204%) and the toughness by âˆ?1 folds from 4.4 to 54.6 MJ m-3 relative to the PLA matrix. Meanwhile, the PLA/20% Mlignin composite retains a tensile strength of 40.9 MPa. Such largely enhanced ductility and toughness of PLA is mainly attributed to the deformation of Mlignin that can dissipate the fracture energy during the tension process. This work not only offers a simple route to converting industrial waste lignin into value-added biobased fillers for polymers and but also provides a new approach for developing low-cost, ductile, and fully sustainable PLA to further its industrial applications. A new class of fully biobased lignin-derived toughening agents has been developed by graft copolymerization and demonstrated an excellent toughening effect on PLA.

Saeed, Mohsin Hassan published the artcileEffects of rigid structures containing (meth)acrylate monomers and crosslinking agents with different chain length on the morphology and electro-optical properties of polymer-dispersed liquid crystal films, Application In Synthesis of 142-90-5, the main research area is acrylic polymer liquid crystal film morphol electrooptical property.

This contribution investigates the preparation of polymer-dispersed liquid crystal (PDLC) films based on meth(acrylate) monomers containing rigid structures. The current study specifically focuses on comparison of the monomers on the basis of meth(acrylate) side group, flexible/rigid structures and rigidity. We find that methacrylate monomers exhibit more preferable electro-optic properties than that of the acrylate monomers. Furthermore, through the systematic variation of rigidity, composition of the monomers and chain length of crosslinking agents, both the morphologies and electro-optic properties of these films are found to be adjustable. A composite film is demonstrated by employing moderately rigid monomer (tetrahydrofurfuryl methacrylate) with low driving voltage (21.0 V) and high contrast ratio (87.5). Therefore, the studies here provide a new approach to optimize the electro-optical properties of the PDLC films by introducing monomers with rigid structures.

Yin, Hanliang published the artcileStudy on the potential contribution of bacterial community on the volatile flavor of Yongfeng chilli paste, HPLC of Formula: 41114-00-5, the main research area is Yongfeng chilli paste volatile flavor bacterial community.

The study aimed to explore the contribution of the microbial community on flavor formation by measuring physicochem. properties, volatile compounds composition and bacterial community of Yongfeng chilli paste. A similar amino acid nitrogen level and different pH, total acid and salt content were observed in five brands of Yongfeng chilli paste. A total of 106 volatile compounds were identified, wherein, Et palmitate, Et trans-4-decenoate, phenylethyl alc. were the common volatile compounds with high content in all samples. Addnl., Oxyphotobacteria-unclassified, Mitochondria-unclassified, Pediococcus, Bacillus, Lactobacillus and Weissella were the dominant genera. Lactobacillus was related to the production of some alcs. and terpenes. Whereas, Bacillus, Pediococcus and Weissella, which showed higher salt tolerance, could affect the formation of esters, such as Et salicylate, Et lactate. Thus, this study provided a basis for further research on the mechanism of flavor formation and some guidance for the improvements of the quality of traditional fermented chilli paste.

Mizumachi, Hideyuki published the artcileCharacterization of dermal sensitization potential for industrial or agricultural chemicals with EpiSensA, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is industrial agricultural chem dermal sensitization potential; DPRA; EpiSensA; KeratinoSensâ„? h-CLAT; in vitro; skin sensitization.

The regulatory community is transitioning to the use of nonanimal methods for dermal sensitization assessments; however, some in vitro assays have limitations in their domain of applicability depending on the properties of chems. being tested. This study explored the utility of epidermal sensitization assay (EpiSensA) to evaluate the sensitization potential of complex and/or ′′difficult to test′â€?chems. Assay performance was evaluated by testing a set of 20 test chems. including 10 methacrylate esters, 5 silicone-based compounds, 3 crop protection formulations, and 2 surfactant mixtures; each had prior in vivo data plus some in silico and in vitro data. Using the weight of evidence (WoE) assessments by REACH Lead Registrants, 14 of these chems. were sensitizers and, six were nonsensitizers based on in vivo studies (local lymph node assay [LLNA] and/or guinea pig studies). The EpiSensA correctly predicted 16/20 materials with three test materials as false pos. and one silane as false neg. This silane, classified as weak sensitizer via LLNA, also gave a ′′false neg.′â€?result in the KeratinoSens assay. Overall, consistent with prior evaluations, the EpiSensA demonstrated an accuracy level of 80% relative to available in vivo WoE assessments. In addition, potency classification based on the concentration showing pos. marker gene expression of EpiSensA was performed. The EpiSensA correctly predicted the potency for all seven sensitizing methacrylates classified as weak potency via LLNA (EC3 â‰?10%). In summary, EpiSensA could identify dermal sensitization potential of these test substances and mixtures, and continues to show promise as an in vitro alternative method for dermal sensitization.
