And the article contained the following:

An anisotropic visco-hyperelastic constitutive model for thermally-actuated woven fabric-reinforced shape memory polymer composites (SMPCs) is proposed. The viscoelasticity of the shape memory polymer and anisotropic hyperelasticity of the fabric are sep. described. The second law of thermodn. is used to derive the constitutive relations through decomposing the thermodn. free energy. A woven fabric-reinforced SMPC is prepared and its thermomech. and shape memory experiments are conducted to verify the proposed model. Comparison between the predicted and experiment results indicates an good consistency, which attests that the developed model can predict the anisotropic mech. and shape memory properties of thermally induced SMPCs reinforced by woven fabrics effectively. And numerical investigation of the effect of fiber yarn orientation on the shape fixity and recovery is also performed. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Product Details of 2358-84-1

Okten Besli, Nur Sena; Orakdogen, Nermin published an article in 2021, the title of the article was Exploring the role of muscovite in poly(alkyl methacrylate)-based ternary nanocomposite cryogels with selective functional groups: formation via cryogelling with the aid of inorganic clay.Application of 2358-84-1 And the article contains the following content:

Easy fabrication of inorganic clay muscovite (MUS) embedded poly(2-acrylamido-2-methyl-1-propane sulfonic acid-co-diethylaminoethyl methacrylate-co-hydroxyethyl methacrylate) (PADH) nanocomposite cryogels with dual temperature/pH dependent catalytic potential was reported. Nanocomposite cryogels were fabricated by a method involving cryogelation and free radical crosslinking of aqueous systems containing MUS ranging from 0% to 1.50% (w/v). The changes in the properties of polybasic PADH networks were investigated to explain how the network parameters and gel properties were affected by the addition of clay, with the formation of a single terpolymer-MUS structure. The potential of the addition of different amounts of MUS to strengthen the prepared terpolymer matrix was investigated by uniaxial compression tests. By lowering the polymerization temperature or increasing the MUS content, the PADH/MUS nanocomposite cryogels became more elastic and compressible with stronger entanglement of terpolymer chains between the clay layers. With the addition of 1.50% (w/v) MUS, the swelling capacity was reduced by 50%, resulting in a two-fold increase in compression elasticity. The nanocomposite gels showed a strong pH-dependence, and when the pH of the swelling medium decreased from 9.8 to 2.1, there was a significant increase in the degree of swelling with increasing protonation of tertiary amine groups. Under an acidic environment, the swelling capacity of the nanocomposite gel containing 1.10% (w/v) MUS increased by 49.5%. In temperature dependent swelling between 15 and 75°C, all ternary PADH/MUS-Ngels showed a tendency to swell at low and high swelling temperatures, by the predominance of DEAEM units at low temperatures and HEMA monomers at high temperatures, resp. As the temperature was increased to 55°C, the swelling decreased and reached a min., and then the nanocomposite gels tended to swell again. The obtained results provide an insight into the effect of MUS addition on the properties of poly(alkyl methacrylate)-based ternary nanocomposite gels and demonstrate a simple and efficient way to produce multiple response systems with enhanced elasticity. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Application of 2358-84-1

On December 31, 2021, Tomal, Wiktoria; Krok, Dominika; Chachaj-Brekiesz, Anna; Lepcio, Petr; Ortyl, Joanna published an article.HPLC of Formula: 2358-84-1 The title of the article was Harnessing light to create functional, three-dimensional polymeric materials: multitasking initiation systems as the critical key to success. And the article contained the following:

Nowadays, the lack of suitable photoinitiators (PI) and photoinitiating systems (PISs) represents the utmost challenge in 3D-VAT printing. High photoinitiating efficiency is needed for example in the presence of nanofillers such as carbon nanotubes (CNTs) which absorb and scatter light. Many prominent PISs contains iodonium salt as an initiator and a second component as a photosensitizer. This study addresses the high demand for innovative PISs with improved photoinitiating efficiency by a complete cycle of research: from the synthesis of new biphenyl derivatives, through their employment as photosensitizers of iodonium salt for light-induced cationic, free-radical, and hybrid polymerization processes, to the representative application in 3D printing processes such as digital light processing (DLP) or laser printing. The ultimate performance of the newly synthesized compounds was tested by preparing 3D-printable photosensitive nanocomposite resins filled with CNTs as a nanoscale filler. Their photopolymerization kinetics as well as the effect of the CNT concentration on the crosslinking were analyzed via real-time FTIR and photo-rheol. The printouts were observed with optical microscopy and SEM. In addition, the key printing parameters were determined, i.e. Ec (critical energy to initiate polymerization) and Dp (penetration depth of curing light). Our results evidence the capability of the synthesized compounds to take part in the photoinitiating systems of complex and demanding 3D printing applications. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).HPLC of Formula: 2358-84-1

And the article contained the following:

Fluorescent microparticles have been prepared by gamma radiation-initiated precipitation polymerization of diethylene glycol dimethacrylate monomer with Et propionate solvent and fluorescein isothiocyanate isomer-I (FITC) fluorophore. Different FITC concentrations and irradiation conditions were used, and their effect on the particle properties was studied. The samples were characterized by SEM, Raman and photoluminescence spectroscopies. Our results showed that the size of the microspheres is dependent on the composition of the monomer mixture The uniformity of the microparticles decreases with increasing FITC concentration, relative to the monomer. Changes in the emission spectrum of the FITC were also observed after irradiation The gamma irradiation-initiated polymerization was found to be a promising and simple technique to prepare luminescent spherical microparticles.

On March 14, 2022, Wang, Hui; Fliedel, Christophe; Manoury, Eric; Poli, Rinaldo published an article.Reference of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) The title of the article was Core-crosslinked micelles with a poly-anionic poly(styrene sulfonate)-based outer shell made by RAFT polymerization. And the article contained the following:

Core-crosslinked micelles (CCMs) with a permanently charged anionic shell of sodium poly(styrene sulfonate) (PSS-Na+) chains were developed by a convergent three-step one-pot RAFT polymerization starting with 4-cyano-4-thiothiopropylsulfanyl pentanoic acid (CTPPA, R0-SC(S)SnPr) as chain transfer agent, which includes polymerization-induced self-assembly (PISA) in the second step. The final crosslinking step of the R0-(SS-Na+)x-b-Sty-SC(S)SnPr diblock chains was carried out with diethylene glycol dimethacrylate (DEGDMA), either diluted into styrene (DEGDMA/St = 10:90) or neat. The morphol. of the intermediate micelles and of the final CCM particles was studied by dynamic light scattering (DLS) and transmission electron microscopy (TEM) as a function of the relative degrees of polymerizations for the shell, core, and crosslinking blocks. Conformational instability was observed for the aqueous dispersions of the diblock micelles, especially with the shorter PSt blocks, yielding equilibrium with single chains and large agglomerates. However, crosslinking led to well-defined CCMs with narrow size distributions for the optimized polymer compositions The DLS anal. in a compatibilizing 60:40 THF/H2O solvent mixture demonstrates that the final step of the polymer synthesis has quant. crosslinked all diblock arms.

Arias, Consuelo; Saavedra, Nicolas; Leal, Karla; Vasquez, Belgica; Abdalla, Dulcineia S. P.; Salazar, Luis A. published an article in 2020, the title of the article was Histological evaluation and gene expression profiling of autophagy-related genes for cartilage of young and senescent rats.Product Details of 2358-84-1 And the article contains the following content:

Autophagy is a cellular mechanism that protects cells from stress by digesting non-functional cellular components. In the cartilage, chondrocytes depend on autophagy as a principal mechanism to maintain cellular homeostasis. This protective role diminishes prior to the structural damage that normally occurs during aging. Considering that aging is the main risk factor for osteoarthritis, evaluating the expression of genes associated with autophagy in senescent cartilage might allow for the identification of potential therapeutic targets for treatment. Thus, we studied two groups of young and senescent rats. A histol. anal. of cartilage and gene expression quantification for autophagy-related genes were performed. In aged cartilage, morphol. changes were observed, such as an increase in cartilage degeneration as measured by the modified Mankin score, a decrease in the number of chondrocytes and collagen II (Col2a1), and an increase in matrix metalloproteinase 13 (Mmp13). Moreover, 84 genes associated with autophagy were evaluated by a PCR array anal., and 15 of them were found to be significantly decreased with aging. Furthermore, an in silico anal. based on by two different bioinformatics software tools revealed that several processes including cellular homeostasis, autophagosome assembly, and aging-as well as several biol. pathways such as autophagy, insulin-like growth factor 1 (IGF-1) signaling, PI3K (phosphoinositide 3-kinase)/AKT (serine/threonine kinase) signaling, and mammalian target of rapamycin (mTOR) signaling-were enriched. In conclusion, the anal. identified some potential targets for osteoarthritis treatment that would allow for the development of new therapeutic strategies for this chronic disease.

Khodeir, Miriam; Jia, He; Vlad, Alexandru; Gohy, Jean-Francois published an article in 2021, the title of the article was Application of redox-responsive hydrogels based on 2,2,6,6-tetramethyl-1-piperidinyloxy methacrylate and oligo(ethyleneglycol) methacrylate in controlled release and catalysis.Reference of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) And the article contains the following content:

Hydrogels have reached momentum due to their potential application in a variety of fields including their ability to deliver active mols. upon application of a specific chem. or phys. stimulus and to act as easily recyclable catalysts in a green chem. approach. In this paper, we demonstrate that the same redox-responsive hydrogels based on polymer networks containing 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) stable nitroxide radicals and oligoethylene glycol Me ether methacrylate (OEGMA) can be successfully used either for the electrochem. triggered release of aspirin or as catalysts for the oxidation of primary alcs. into aldehydes. For the first application, we take the opportunity of the pos. charges present on the oxoammonium groups of oxidized TEMPO to encapsulate neg. charged aspirin mols. The further electrochem. reduction of oxoammonium groups into nitroxide radicals triggers the release of aspirin mols. For the second application, our hydrogels are swelled with benzylic alc. and tert-Bu nitrite as co-catalyst and the temperature is raised to 50°C to start the oxidation reaction. Interestingly enough, benzaldehyde is not miscible with our hydrogels and phase-sep. on top of them allowing the easy recovery of the reaction product and the recyclability of the hydrogel catalyst.

And the article contained the following:

The mechanisms underlying abdominal aortic aneurysms (AAAs) are still not fully understood, previous researches showed ADAM17 is increased in aneurysm. We hypothesized that inhibiting ADAM17 can decrease AAA formation and progression. Aneurysm models were established in mouses and rats by aortic adventitial CaCl2 incubation and aortic pericardial patch angioplasty resp. In mouse, control (no treatment) or SA/HA hydrogel loaded with TAPI-1 (ADAM17 inhibitor) were adventitial applied; in rat, control and TAPI-1 coated pericardial patch were used in rat aortic pericardial patch angioplasty. Samples were harvested on day 14 or 30 and analyzed by immunofluorescence. Bioinformatics anal. and immunostaining anal. were carried out to confirm the therapeutic potential of ADAM17 in the human AAA. ADAM17 was highly expressed in mouses, rats and human aneurysms. Adventitial application of SA/HA hydrogel loaded TAPI-1 or TAPI-1 conjugated pericardial patch can decrease AAA formation and progression in mouses and rats, resp. Bioinformatic anal. showed ADAM17 promotes transformation of M1 macrophages and synthetic vascular smooth muscle cells, together with immunostaining anal. and results from animal models, the therapeutic potential of ADAM17 in the human AAA were confirmed. We showed that local delivery of ADAM17 inhibitor can inhibit aneurysm formation and progression in mouse and rat, these results showed ADAM17 plays an important role in the aneurysm formation and may be a potential treatment target.

da Silva, Erotides Capistrano; Arrington, Justine; Yau, Peter M.; Smith-Fleming, Kathryn M.; Canisso, Igor Frederico; da Costa Martins, Bianca published an article in 2021, the title of the article was Proteome composition of bovine amniotic membrane and its potential role in corneal healing.Application of 2358-84-1 And the article contains the following content:

To investigate the protein profile of bovine amniotic membranes (bAM) and to determine putative associations between protein composition in bAM and known corneal healing pathways. The bAM were acquired from normal full-term births (n = 10), processed, and stored at -80°C for two days. Subsequently, the frozen membranes were thawed at room temperature and prepared for proteomic exploration using high-resolution liquid chromatog.-mass spectrometry, followed by bioinformatics anal. Recently identified corneal healing pathways were contrasted with protein profiles and pathways present in bAM. Results. The analyses identified 2105 proteins, with an interactive network of 1271 nodes (proteins) and 8757 edges (interactions). The proteins with higher betweenness centrality measurements include microfibril-associated protein 4, HSD3B1, CAPNS1, ATP1B3, CAV1, ANXA2, YARS, and GAPDH. The top four pathways in Kyoto Encyclopedia of Genes and Genomes were ribosome, metabolic pathway, spliceosome, and oxidative phosphorylation. The bAM and cornea shared abundant proteins, genome ontol., and signaling pathways. The high-throughput proteomic profile of the bAM demonstrated that numerous proteins present in the cornea are also present in this fetal membrane. Our findings collectively demonstrate the similarity between bAM and the cornea’s protein composition, supporting our hypothesis that bAM can be used to treat corneal diseases.

And the article contained the following:

Quantum dots (QDs) are considered for devices like light-emitting diodes (LEDs) and photodetectors as a result of their tunable optoelectronic properties. To utilize the full potential of QDs for optoelectronic applications, control over the charge carrier d. is vital. However, controlled electronic doping of these materials has remained a long-standing challenge, thus slowing their integration into optoelectronic devices. Electrochem. doping offers a way to precisely and controllably tune the charge carrier concentration as a function of applied potential and thus the doping levels in QDs. However, the injected charges are typically not stable after disconnecting the external voltage source because of electrochem. side reactions with impurities or with the surfaces of the QDs. Here, we use photopolymerization to covalently bind polymerizable electrolyte ions to polymerizable solvent mols. after electrochem. charge injection. We discuss the importance of using polymerizable dopant ions as compared to nonpolymerizable conventional electrolyte ions such as LiClO4 when used in electrochem. doping. The results show that the stability of charge carriers in QD films can be enhanced by many orders of magnitude, from minutes to several weeks, after photochem. ion fixation. We anticipate that this novel way of stable doping of QDs will pave the way for new opportunities and potential uses in future QD electronic devices. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Safety of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)
