Wan, Xizi published the artcileWET-Induced Layered Organohydrogel as Bioinspired “”Sticky-Slippy Skin”” for Robust Underwater Oil-Repellency, Application In Synthesis of 142-90-5, the main research area is nanoclay organohydrogel underwater superoleophobicity; anti-oil-fouling; interfacial adhesion; sticky−slippy skin; underwater superoleophobicity; wetting-enabled-transfer.

Underwater superoleophobic surfaces featuring anti-oil-fouling properties are of great significance in widespread fields. However, their complicated engineering process and weak interfacial adhesion strength with underlying substrates severely hamper these ideal surfaces toward practical applications. Here, a moss-inspired sticky-slippy skin composed of layered organohydrogel is reported through a one-step wetting-enabled-transfer (WET) strategy, which unprecedentedly integrates robust inherent adhesion with durable anti-oil-fouling properties. The sticky organogel layer can be simply attached to various substrates, from metals and plastics to glass, independent of any surface pretreatment. The slippy hydrogel layer enables stable underwater superoleophobicity and ultralow oil adhesion for diverse kinds of oils. The sticky-slippy skin features outstanding comprehensive properties including easy-pasting, anti-swelling/anti-bending, compatibility with com. adhesives, acid/alkali resistance, environmental friendliness, and substrate universality. The design strategy with integrated functions provides a clue to accelerate the development of bioinspired multifunctional interfacial materials toward real-world applications.

Seto, Ryota published the artcileSynthesis of block copolymers through umpolung or treatment of propagating end of living cationic polytetrahydrofuran, Computed Properties of 142-90-5, the main research area is living polytetrahydrofuran anionic radical block polymerization diblock copolymer.

Block copolymers containing polyTHF segments were synthesized by umpolung or propagating end of the cationic living polymer and successive anionic polymerization of methacrylates (RMAs) or radical polymerization of RMAs, acrylonitrile (AN), and styrene (St). Living polyTHF (poly-THF) was prepared by cationic polymerization of THF, whose propagation end was reduced by Sm(II) iodide (SmI2). Anionic polymerizations of RMAs were conducted by addition of the monomers to the reduced poly-THF to obtain poly(THF-b-RMAs). However, the 2-bromoisobutyrate group, which can act as an initiator of radical polymerization, was introduced to the cationic propagating end of poly-THF by adding Na 2-bromoisobutyrate. Block copolymers were synthesized by living radical polymerization of RMAs, St, or AN using the 2-bromoisobutyrate-capped poly-THF as a macroinitiator and Cu(I) bromide (CuBr) as a catalyst.

Zhao, Zhen published the artcileTough and self-healing hydrophobic association hydrogels with cationic surfactant, Application In Synthesis of 142-90-5, the main research area is acrylamide lauryl methacrylate copolymer hydrogel micellar copolymerization hydrophobic association; mech rheol self healing property.

Hydrophobic association (HA) hydrogels with outstanding mech., rheol. and recovery properties were successfully synthesized by micellar copolymerization of acrylamide with lauryl methacrylate. The synthesis occurred at room temperature and the synthesis condition was moderate by using the redox initiator system of ammonium persulfate – sodium bisulfite as initiators. Cationic surfactant (dodecyl tri-Me ammonium bromide) was utilized to form micelles with hydrophobe, served as phys. crosslinking points in the 3D networks of hydrogels. The HA hydrogels showed a high tensile strength of 181 kPa, superior stretchability of 2300% and excellent toughness of 2.16 MJ m-3. Moreover, they owned extraordinary self-recovery under different conditions. It is hopeful that the hydrogels with superior mech. strength and self-healing properties would be applied to the fields of biomedicine and engineering. Meanwhile, based on above materials, HA hydrogels could also be synthesized with the combination of hydrophobic association and other synergistic effects, such as latex particles, electrostatic effect and nanoparticles.

Li, Youqiang published the artcileA highly sensitive strain sensor based on a silica@polyaniline core-shell particle reinforced hydrogel with excellent flexibility, stretchability, toughness and conductivity, Category: esters-buliding-blocks, the main research area is polyaniline silica core shell particle reinforced hydrogel strain sensor.

Hydrogel-based flexible strain sensors for personal health monitoring and human-machine interaction have attracted wide interest among researchers. In this paper, hydrophobic association and nanocomposite conductive hydrogels were successfully prepared by introducing polyaniline coated silica (SiO2@PANI) core-shell particles into an acrylamide-lauryl methacrylate (P(AM/LMA)) copolymer matrix. The hydrophobic interaction between the SiO2@PANI core-shell particles and the hydrophobic LMA in the P(AM/LMA) chains induced the hydrogels with outstanding mech. properties. Furthermore, the polyaniline on the SiO2 surface and the inorganic salt formed a conductive network, which synergistically enhanced the conductivity of the hydrogels. The obtained hydrogels integrate high tensile strength (1398 kPa), ultra-stretchability (>1000%), wonderful strain sensitivity (gauge factor = 10.407 at 100-1100% strain), quick response (300 ms), and excellent durability (>300 cycles) due to the hydrophobic association and nanocomposite effect. The prepared SiO2@PANI-P(AM/LMA) hydrogel shows high stress sensitivity to detect human movements and displays a broad application prospect in flexible strain-sensor field.

Liu, Guiju published the artcileIntegration of photoelectrochemical devices and luminescent solar concentrators based on giant quantum dots for highly stable hydrogen generation, Synthetic Route of 142-90-5, the main research area is photoelectrochem cell luminescent solar concentrator quantum dot hydrogen evolution; cadmium sulfide selenide quantum dot photosensitizer hydrogen evolution photostability.

Hydrogen generation from water under sunlight illumination is the key to construct a sustainable and clean energy system. To date, the long-term stability of photoanodes based on colloidal quantum dots (QDs) for hydrogen generation remains a major challenge due to the degradation of the QDs and hole accumulation. The degradation is usually caused by the self-oxidation of QDs induced by UV radiation. Here, we propose a concept of integrating a luminescent solar concentrator (LSC) with a photoelectrochem. (PEC) cell into a standalone device to improve the stability of the PEC device for hydrogen generation by avoiding direct irradiation of UV light on PEC devices. In this study, CdSe/(CdSxSe1-x)5/CdS core/multi-shell QDs were used as a photosensitizer. The PEC device based on alloyed multi-shell QDs shows a saturated photocurrent d. of 11.5 mA cm-2 and maintains �6.2% of its initial value after 23 h of sunlight illumination (100 mW cm-2). PEC devices based on QDs coupled with an LSC exhibit a saturated photocurrent d. of 1.2 mA cm-2, and �4.6% of its initial value was retained after 23 h of continuous illumination, indicating a 420% enhancement compared to a PEC device alone. This finding proves a unique concept to improve the photo-stability of PEC devices by coupling with an LSC.

Gao, Yong published the artcileIonic liquid-containing non-aqueous Pickering emulsions prepared with sterically-stabilized polymer nanoparticles: A highly efficient platform for Knoevenagel reaction, Application of Dodecyl 2-methylacrylate, the main research area is ionic liquid Pickering emulsion polymer nanoparticle Knoevenagel reaction.

Room temperature ionic liquids (RTILs)-containing Pickering emulsions exhibit promising application potentials because of the integration of the “”green”” quality and the tunable applications of RTILs with the advantages of Pickering emulsions, such as the high stability and adjustable droplet size. In the present study, sterically-stabilized polymer nanoparticles (SSPNs) were first prepared via the reversible addition-fragmentation chain transfer (RAFT)-mediated non-aqueous dispersion polymerization, in which poly(lauryl methacrylate) (PLMA) and poly(4-vinyl pyridine) (P4VP) acted as the stabilizer block and the core-forming block, resp. Kinetically-trapped PLMA-b-P4VP spheres and mixed spherical/worm-like morphologies could be achieved at a target copolymer composition Subsequently, core cross-linked SSPNs (CSSPNs) were obtained by means of chem. crosslinking of P4VP cores of SSPNs with 1,4-dibromobutane in a diluted solution of SSPNs in toluene (0.4 mg/mL). Stable 1-butyl-3-methylimidazolium tetrafluoroborate-in-toluene ([Bmim][BF4]-in-toluene) non-aqueous Pickering emulsions could be formed at a low emulsifier content of 0.005 wt% adopting CSSPNs with mixed spherical/worm-like morphologies as Pickering emulsifiers. Benefiting from large surface areas of Pickering emulsions and unique chem./phys. properties of RTILs, [Bmim][BF4]-in-toluene Pickering emulsions provided readily available platforms for many organic reactions. As a proof of the concept, proline catalyzed Knoevenagel reaction of 4-nitrobenzaldehyde with malononitrile was chosen as a model here. Both high reaction efficiency and good recyclability were observed

Zeng, Min published the artcileTailoring the droplet size of Pickering emulsions by PISA synthesized polymeric nanoparticles, Application In Synthesis of 142-90-5, the main research area is tailoring droplet size pickering emulsion.

Pickering emulsions, water or oil droplets stabilized solely by solid particles, are attracting increasing attention, due to the fascinating possibilities for applications in food, pharmaceuticals and preparation of hybrid materials. In this paper, we report oil-in-water (O/W) Pickering emulsions stabilized solely by polymerization-induced self-assembly (PISA) synthesized diblock copolymer spherical nanoparticles. Poly(N,N-dimethylaminoethyl methacrylate)-b-poly(benzyl methacrylate) (PDMA-b-PBzMA) diblock copolymer nanoparticles with 20 wt% solid content were prepared in ethanol via RAFT dispersion polymerization Then PDMA-b-PBzMA nanoparticles were used as emulsifiers to prepare O/W Pickering emulsions by homogenization. The regulation of droplet size of the O/W Pickering emulsion was systemically investigated by adjusting the size of emulsifiers, the concentration of emulsifiers, and the ratio of oil/water. Moreover, Pickering emulsion polymerization was successfully applied to prepare poly (laurate methacrylate) microparticles. These results provide instructive insights to choose proper nanoparticles for the preparation of Pickering emulsions and control over the size of emulsion droplets.

Rymaruk, Matthew J. published the artcileOil-in-oil Pickering emulsions stabilized by diblock copolymer nanoparticles, COA of Formula: C16H30O2, the main research area is Pickering emulsion diblock copolymer nanoparticle; Block copolymers; Nanoparticles; Pickering emulsions; Self-assembly.

Diblock copolymer nanoparticles have been shown to be Pickering emulsifiers for both oil-in-water and water-in-oil emulsions. Recently, we reported the preparation of sterically-stabilized diblock copolymer spheres in a low-viscosity silicone oil (Macromols. 53 (2020) 1785-1794). We hypothesized that such spheres could be used as a Pickering emulsifier for a range of oil-in-oil emulsions comprising droplets of a bio-sourced oil dispersed in silicone oil. Diblock copolymer spheres were prepared via reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization of benzyl methacrylate in silicone oil and characterized by dynamic light scattering and transmission electron microscopy. These spheres were evaluated as Pickering emulsifiers for a series of oil-in-oil Pickering emulsions. The influence of both sphere size and core-forming block composition was investigated. Optimization of the nanoparticle size and core-forming block composition enabled stable bio-sourced oil-in-silicone emulsions to be obtained for nine out of the ten bio-sourced oils investigated. These emulsions were characterized in terms of their mean droplet size by optical microscopy.

Fang, Chen published the artcileGradient polarity solvent wash for separation and analysis of electrolyte decomposition products on electrode surfaces, Application In Synthesis of 142-90-5, the main research area is LIB electrode SEI analysis gradient polarity solvent wash.

The solid electrolyte interphase (SEI) formed during the cycling of lithium-ion batteries (LIBs) by decomposition of electrolyte mols. has key impact on device performance. However, the detailed decomposition process and distribution of products remain a mystery due to the wide variety of electrochem. pathways and the lack of facile anal. methods for chem. characterization of SEIs. In this report, a gradient polarity solvent wash technique involving the use of solvents with gradually increased polarities is employed to sequentially remove different SEI components from electrode surfaces. Fourier transform IR (FTIR) spectroscopy is utilized to characterize the SEI composition The impacts of electrolyte additives and discharge rates over SEI formation are illustrated. This study presents a new concept of rationally controlled solvent wash technique for electrode surface anal. that can selectively remove targeted components. The findings in this study provide exptl. support for the slow charge formation processes commonly employed for LIBs in industry.
