Kakiuchi, Ryo published the artcileA 19F-MRI probe for the detection of Fe(II) ions in an aqueous system, Formula: C9H20O5, the main research area is MRI probe detection iron.

Iron deposits are often observed in the brains of patients with neurodegenerative diseases, including Alzheimer′s and Parkinson′s diseases. This study outlines the development of F-Nox-1 (I) as the first example of a 19F-MRI probe that can selectively detect Fe(II) in aqueous solutions The use of tetrafluoro-p-phenylenediamine (TFPDA) as a 19F signal emitter with an Fe(II)-selective chem. switch, based on our previously reported N-oxide chem., yielded a readout of a symmetry-dependent 19F signal change in response to Fe(II). The addition of Fe(II) ions to F-Nox-1 triggered a 19F signal change, both in the chem. shift and signal intensity, and the response was highly selective to Fe(II) over other biol. relevant metal ions. The probe could also detect Fe(II) in serum containing various biol. contaminants by 19F magnetic resonance imaging (19F-MRI). Imaging of soluble Fe(II) species, which is the major component of water-soluble iron species, by 19F-MRI will potentially enable the direct monitoring of the elevation of Fe(II) levels prior to the formation of iron deposits, which is a potential risk factor for neurodegenerative diseases.

Ryskulova, Kanykei published the artcileEffect of Host-Guest Complexation on the Thermoresponsive Behavior of Poly(oligo ethylene glycol acrylate)s Functionalized with Dialkoxynaphththalene Guest Side Chains, Name: 2,5,8,11-Tetraoxatridecan-13-ol, the main research area is host guest complexation thermoresponsive behavior polyoligoethyleneglycol acrylate functionalized dialkoxynaphththalene; LCST; host-guest complexation; responsive polymers; supramolecular chemistry.

The combination of thermoresponsive polymers with supramol. host-guest interactions enables accurate tuning of the phase transition temperature, while also providing addnl. response mechanisms based on host-guest complexation. Most studies focused on a single thermoresponsive polymer to demonstrate the effect of host-guest complexation on the responsive behavior. In this work, the effect of the polymer structure on the host-guest complexation and thermoresponsive behavior is reported. Therefore, different poly(oligoethylene glycol acrylate)s, namely, poly(2-hydroxyethylacrylate) (PHEA), poly(methoxy diethylene glycol acrylate), poly(methoxy triethylene glycol acrylate), and poly(methoxy tetraethylene glycol acrylate), are synthesized functionalized with 1,5-dialkoxynaphthalene guest mols. in the side chain. Their complexation with the cyclobis(paraquat-p-phenylene) tetrachloride host is studied to understand the effect of polymer structure on the supramol. association and the polymer phase transition, revealing that the oligoethylene glycol side chains lead to weaker host-guest complexation and also have a smaller increase in the cloud point temperature compared to PHEA.

Atchimnaidu, Siriki published the artcilePhototheranostic DNA micelles from the self-assembly of DNA-BODIPY amphiphiles for the thermal ablation of cancer cells, Product Details of C9H20O5, the main research area is phototheranostic DNA micelle BODIPY amphiphile cancer cell thermal ablation.

Design of phototheranostic agents in a single step approach is one of the challenges in cancer therapy. Herein, a one-step strategy based on amphiphilicity-driven self-assembly of DNA-BODIPY amphiphiles for the design of a new class of micelles, which offer all three phototheranostic functions, is reported. These include (i) strong emission at NIR (ϕf = 30%) for imaging, (ii) high photothermal conversion (η = 52%) for PTT and (iii) an ssDNA-based shell for the integration of cell targeting moieties. Selective uptake of DNA micelles into a target cancer cell and its killing by laser irradiation (635 nm) are also demonstrated. Furthermore, the excellent biocompatibility, ultrasmall nanosize and high stability of DNA micelles are promising for in vivo applications.

Moser, Maximilian published the artcileSide Chain Redistribution as a Strategy to Boost Organic Electrochemical Transistor Performance and Stability, Safety of 2,5,8,11-Tetraoxatridecan-13-ol, the main research area is organic electrochem transistor performance stability polythiophene side chain redistribution; bioelectronics; ethylene-glycol-functionalized polymers; mixed ionic-electronic conduction; organic electrochemical transistors.

A series of glycolated polythiophenes for use in organic electrochem. transistors (OECTs) is designed and synthesized, differing in the distribution of their ethylene glycol chains that are tethered to the conjugated backbone. While side chain redistribution does not have a significant impact on the optoelectronic properties of the polymers, this mol. engineering strategy strongly impacts the water uptake achieved in the polymers. By careful optimization of the water uptake in the polymer films, OECTs with unprecedented steady-state performances in terms of [μC*] and current retentions up to 98% over 700 electrochem. switching cycles are developed.

Haramiishi, Yoshiaki published the artcileViscoelastic evaluation of poly(trimethylene carbonate)s bearing oligoethylene glycol units which show thermoresponsive properties at body temperature, Computed Properties of 23783-42-8, the main research area is viscoelasticity polytrimethylene carbonate oligoethylene glycol thermoresponsive body temperature.

Poly(trimethylene carbonate) (PTMC) derivatives have been extensively researched for use as low-toxicity biomaterials. Better biocompatibility and lower toxicity have been achieved by eliminating acid generation from the ester group at the side chains. In this study, thermosensitive PTMC derivatives bearing oligo(ethylene glycol) units are synthesized by ring-opening polymerization for the development of low-toxicity and thermosensitive soft materials. The viscoelastic properties of the obtained polymers are then investigated by rheometry to clarify the thermosensitive and mol. weight effects. Furthermore, thermosensitive behaviors and dynamics of these polymers are observed by UV-vis transmittance, DSC, and 1H NMR spectra anal. These data suggest a mechanism for the thermosensitive behavior where it is surmised that some kind of dehydration phenomenon induces aggregation behavior in aqueous media above lower critical solution temperature These thermosensitive behaviors provide an important road map for the development of thermosensitive soft materials using ester-free PTMC derivatives by controlling the thermosensitive behaviors and bulk properties.

Son, Seoung-Bum published the artcileSystematic study of the cathode compositional dependency of cross-talk behavior in Li-Ion battery, HPLC of Formula: 23783-42-8, the main research area is lithium ion battery cathode oxide electrolyte.

While LiNixMnyCo1 – x – yO2 (NMC) is one of the most widely used cathode materials for lithium-ion batteries (LIBs), the composition of NMC is evolving to Ni-rich NMC to achieve higher lithium capacity that fulfills the constant demand for LIBs with ever-higher energy densities. The change in the composition of NMC affects electrochem. features and electrode cross-talk, which explains the performance change during cycling. In this study, we introduce various NMC materials (LiNi0.5Mn0.3Co0.2O2, LiNi0.6Mn0.2Co0.2O2 and LiNi0.8Mn0.1Co0.1O2) to reveal how the NMC composition affects electrode cross-talk. The study reveals that NMC composition strongly affects transition metal dissolution; dissolution of manganese linearly decreases as its stoichiometric ratio in NMC decreases, while dissolution of nickel is only prominent in LiNi0.8Mn0.1Co0.1O2. Aged electrolyte samples are characterized with high-performance liquid chromatog., and two electrolyte decomposition species, C8H16O5 and C9H18O5, are identified across all samples.

Rousseva, Sylvia published the artcileReaching a Double-Digit Dielectric Constant with Fullerene Derivatives, Recommanded Product: 2,5,8,11-Tetraoxatridecan-13-ol, the main research area is oligoethylene glycol fullerene derivative homologous series dielec constant.

The dielec. constant (εr) of organic semiconductors is a key material parameter for improving device performance in the field of organic electronics. However, the effect of the dielec. constant on the electronic and optoelectronic properties of materials remains unclear due to the scarcity of known organic semiconductors with an εr value higher than 6. Herein, the optical and electronic properties of a homologous series of fullerene derivatives with high εr are studied. The low frequency (<106 Hz) εr is extracted from the capacitance measured using impedance spectroscopy, and the effect of length (n) and geometrical arrangement of the polar ethylene glycol (EG) side chains is investigated. The εr is found to correlate with length for the sym. Bingel adducts, whereas for the unsym. branched-EG chain adducts there is no significant difference between the two EG chain lengths. For BTrEG-2, the εr reaches 10, which is an unprecedented value in monoadduct fullerene derivatives These materials open up new possibilities of studying the effect of εr in organic electronic devices such as organic photovoltaics, organic thermoelecs., and organic field-effect transistors.

Anon, Elena published the artcileNot always what closes best opens better: mesoporous nanoparticles capped with organic gates, Name: 2,5,8,11-Tetraoxatridecan-13-ol, the main research area is mesoporous nanoparticle gated nanodevice esterase controlled release; 10 Engineering and Structural materials; 102 Porous / Nanoporous / Nanostructured materials; Mesoporous nanoparticles; esterase controlled release; gated nanodevices.

Four types of calcined MCM-41 silica nanoparticles, loaded with dyes and capped with different gating ensembles are prepared and characterized. N1 and N2 nanoparticles are loaded with rhodamine 6G and capped with bulky poly(ethylene glycol) derivatives bearing ester groups (1 and 2). N3-N4 nanoparticles are loaded with sulforhodamine B and capped with self-immolative derivatives bearing ester moieties. In the absence of esterase enzyme negligible cargo release from N1, N3 and N4 nanoparticles is observed whereas a remarkable release for N2 is obtained most likely due to the formation of an irregular coating on the outer surface of the nanoparticles. In contrast, a marked delivery is found in N1, N3, and N4 in the presence of esterase enzyme. The delivery rate is related to the hydrophilic/hydrophobic character of the coating shell. The use of hydrophilic poly(ethylene glycol) derivatives as gating ensembles on N1 and N2 enables an easy access of esterase to the ester moieties with subsequent fast cargo release. On the other hand, the presence of a hydrophobic monolayer on N3 and N4 partially hinders esterase enzyme access to the ester groups and the rate of cargo release was decreased.

Qian, Xiaomin published the artcileDistinguishing Commercial Beers Using a Solution-Based Sensor Array Derived from Nanoscale Polydiacetylene Vesicles, Safety of 2,5,8,11-Tetraoxatridecan-13-ol, the main research area is polydiacetylene vesicle solution sensor array beer.

The fast and effective discrimination of different liquid mixtures such as beers is a long-standing challenge in the food and beverage industry. We report the fabrication of a solution-based sensor array derived from nanoscale polydiacetylene (PDA) vesicles to distinguish different ethanol containing aqueous solutions supplemented with different model flavor compounds relevant in beers. The sensitivity of the sensors was significantly affected by the head group modification of the diacetylenes and the composition of the sensors. Finally, a selected set of sensors was utilized as a sensor array to distinguish different com. beers in combination with statistical data anal. This approach represents an effort toward the employment of low-cost sensors with an easy read-out for the fast discrimination of different beverages.

Xie, Heping published the artcileElectricity generation by a novel CO2 mineralization cell based on organic proton-coupled electron transfer, SDS of cas: 23783-42-8, the main research area is carbon dioxide organic proton coupled electron transfer electricity mineralization.

Carbon dioxide (CO2) mineralization is an advantageous and effective way to reduce CO2 emissions. In previous work, our research group presented a CO2 mineralization cell that sued alk. solid waste and CO2 as raw materials to produce both electricity and baking soda. Two generations of the cell have been developed. In this paper, we report a novel version of the CO2 mineralization cell in which a highly soluble, proton-coupled electron transfer (PCET), organic redox couple is used to facilitate CO2 mineralization and electricity generation without the need of a precious metal catalyst such as platinum. The cell presented a maximum power d. of 96.75 W m-2 (much higher than that the previously reported mineralization cells without a PCET redox couple). This cell could generate 146 kWh per ton of CO2 mineralized. The reaction mechanism of the cell is based on PCET considerably improved power generation capacity towing to the excellent characteristics of the organic catalyst. This idea provides a new direction toward solving the problem of needing precious metal catalysts in fuel cells.
