Polymer nanocomposites containing well-exfoliated nanoplatelets have been shown to possess greatly enhanced phys. and mech. properties. However, it is still a significant challenge to achieve adequate exfoliation of 2D nanoplatelets in polyolefin matrixes due to poor compatibility and associated entropic penalty between 2D inorganic filler and nonpolar polyolefin matrixes. Grafting polyolefin chains onto the surfaces of an already exfoliated nanoplatelet is a simple, yet effective solution to this problem. The grafted polyolefin chains on the nanoplatelets can entangle and cocrystallize with the polyolefin matrix, preventing agglomeration. In this study, polyethylene (PE) grafted ¦Á-zirconium phosphate (ZrP), ZrP-g-PE, was prepared and blended with the PE matrix. The graft d. of ZrP-g-PE was designed to maintain ZrP exfoliation during subsequent blending with the PE matrix. It was found that PE confined crystallization formed in ZrP-g-PE, resulting in the formation of PE crystal orientation perpendicular to the ZrP nanoplatelets. The usefulness of this study for preparation of high-performance polyolefin nanocomposites is discussed.

Wang, Shuai published the artcileLipase immobilization on multi-walled carbon nanotubes used as a target fishing tool and followed by molecular docking technique to analyze lipase inhibitor from Robinia pseudoacacia L., Synthetic Route of 13822-56-5, the publication is Industrial Crops and Products (2022), 114645, database is CAplus.

In this study, R. pseudoacacia flowers exhibited potential lipase (Aspergillus niger) inhibitory activity. To quickly explore the active compound, ligand fishing was adopted for screening the ligand from R. pseudoacacia flowers by lipase immobilized on magnetic polyamidoamine dendrimer-coated multi-walled carbon nanotubes. After ligand fishing, the target compound was separated purposefully by optimizing the separation conditions of high-speed counter-current chromatog. (HSCCC). As results, kaempferol with the IC50 of 327.64 ¡À 15.33¦Ìg/mL was separated and identified. The further mol. docking results indicated that kaempferol was interacted with amino acid residue in the active site of lipase through van der Waals force, hydrogen bonds and Pi-Pi T-shaped interactions, yielding the binding energy of – 6.43 kcal/mol. The present method not only revealed the lipase inhibitory substances in R. pseudoacacia, but also provided an effective means for the screening of other natural substances.

Amesh, Pamarthi published the artcileEfficient and selective adsorption of U(VI) by succinic acid modified iron oxide adsorbent, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is Radiochimica Acta (2022), 110(5), 333-347, database is CAplus.

The iron oxide surface was modified with succinic acid moiety and the adsorbent obtained, Fe-SUC, was evaluated for the adsorption of U(VI) (Uranium (VI)) from aqueous solution The Fe-SUC was characterized by FT-IR (Fourier Transform IR Spectroscopy), Raman spectroscopy, thermogravimetry, X-ray diffraction, SEM-EDX (Scanning Electron Microscope – Energy-dispersive X-ray Spectroscopy), and particle size anal. The adsorption behavior of U(VI) on Fe-SUC was studied as a function of pH, contact time, and concentration of U(VI) in the aqueous phase. The adsorption of U(VI) increased with increase in the pH of aqueous phase, and the adsorption saturation occurred at pH = 6. The kinetic data obtained for the adsorption of U(VI) on Fe-SUC were modeled with the pseudo-first-order and pseudo-second-order rate models. Similarly, the U(VI) adsorption isotherm was fitted with Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich adsorption isotherm models. The Langmuir adsorption capacity of U(VI) on Fe-SUC was about ?176 mg g^-1. The selectivity of the adsorbent toward U(VI) was evaluated in the presence of several possible interfering ions. The adsorbed U(VI) was recovered by 0.5 M sodium carbonate solution and the spent adsorbent was tested for its reusability.

Reid, Michael S. published the artcileTunable Adhesion and Interfacial Structure of Layer-by-Layer Assembled Block co-polymer Micelle and Polyelectrolyte Coatings, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is Advanced Materials Interfaces (2022), 9(17), 2200065, database is CAplus.

Understanding and tuning nanoscale structure is critical in developing new coatings and adhesives. In this work layer-by-layer assembly of block co-polymer (BCP) micelles and oppositely charged polyelectrolytes produces structurally unique coatings with wet adhesion comparable to that of mussel adhesive proteins. Cationic (CAT) and anionic (ANI) BCPs, synthesized by atom transfer radical polymerization (ATRP), are used to create colloidally stable, self-assembled, spherical BCP micelles. The assembly of BCP micelle and polyelectrolyte multilayers is monitored in situ where CAT- and ANI-BCP micelles exhibit linear and super-linear growth, resp. Imaging of the surfaces reveals that CAT-BCP micelles yield flat, uniform layers whereas ANI-BCP micelle assemblies form islands that increase in surface area with each addnl. layer. The adhesion of these layers, measured by colloidal probe at. force microscopy (CP-AFM), shows that the distinct layers of CAT-BCP micelle assemblies produce alternating high and low adhesion surfaces whereas ANI-BCP micelle assemblies continually increase in adhesion with each addnl. bilayer. The unique behavior of each assembly demonstrates that both composition and structure play important roles in wet adhesion of submicron layers and that each can be tuned to target performance for different applications.

Watanabe, Masashi published the artcileCoil Formation of a Silicone String Using UV-Ozone Treatment, Recommanded Product: 3-(Trimethoxysilyl)propan-1-amine, the publication is ACS Omega (2022), 7(13), 11363-11370, database is CAplus and MEDLINE.

Microcoils are used in various mech. devices. However, existing methods for producing microcoils from polymers often require expensive equipment. In this study, microcoils were prepared using a cost-effective and simple method. The material used was silicone, which is a biocompatible polymeric material. Silicone was solidified inside glass capillaries to form thin, straight strings with a diameter of 140¦Ìm. The string was then transformed to a coil shape by oxidation using UV-ozone treatment while it was prestretched and pretwisted. The resilience force from the prestretching and pretwisting forces caused the string to bend and twist, resp. As a result of the combination of these deformation modes, a coil was formed. As an application of the coils, an actuator was prepared, which repeatedly transforms between straight and coiled shapes. The actuation was caused by the swelling/deswelling of silicone with hexane. A large strain of 54% was obtained.

Stavropoulou, Anastasia P. published the artcileBimetallic gold-platinum nanoparticles as a drug delivery system coated with a new drug to target glioblastoma, HPLC of Formula: 13822-56-5, the publication is Colloids and Surfaces, B: Biointerfaces (2022), 112463, database is CAplus and MEDLINE.

A drug delivery nanosystem of noble bimetallic nanoparticles (NPs) which consists of Au NPs capped with Pt NPs (Au@Pt NPs) is constructed and functionalised with a quinazoline based small mol. (Au@Pt@Q NPs), acting as a theranostic agent against glioblastoma. Two different hydrothermal synthetic procedures for bimetallic Au@Pt NPs are presented and the resulting nanostructures are fully characterised by means of spectroscopic and microscopic methods. The imaging and targeting capacity of the new drug delivery system is assessed through fluorescent optical microscopy and cytotoxicity evaluations. The constructed Au@Pt NPs consist a monodispersed colloidal solution of 25 nm with photoluminescent, fluorescent and X-Ray absorption properties that confirm their diagnostic potential. Haemolysis testing demonstrated that Au@Pt NPs are biocompatible and fluorescent microscopy confirmed their entering the cells. Cytol. evaluation of the NPs through MTT assay showed that they do not inhibit the proliferation of control cell line HEK293, whereas they are toxic in U87MG, U251 and D54 glioblastoma cell lines; rendering them selective targeting agents for treating glioblastoma.

Wu, Xun published the artcileSize-Controlled Nanoparticles Embedded in a Mesoporous Architecture Leading to Efficient and Selective Hydrogenolysis of Polyolefins, Name: 3-(Trimethoxysilyl)propan-1-amine, the publication is Journal of the American Chemical Society (2022), 144(12), 5323-5334, database is CAplus and MEDLINE.

A catalytic architecture, comprising a mesoporous silica shell surrounding platinum nanoparticles (NPs) supported on a solid silica sphere (mSiO₂/Pt-X/SiO₂; X is the mean NP diameter), catalyzes hydrogenolysis of melt-phase polyethylene (PE) into a narrow C₂₃-centered distribution of hydrocarbons in high yield using very low Pt loadings (?10^-5 g Pt/g PE). During catalysis, a polymer chain enters a pore and contacts a Pt NP where the C-C bond cleavage occurs and then the smaller fragment exits the pore. mSiO₂/Pt/SiO₂ resists sintering or leaching of Pt and provides high yields of liquids; however, many structural and chem. effects on catalysis are not yet resolved. Here, we report the effects of Pt NP size on activity and selectivity in PE hydrogenolysis. Time-dependent conversion and yields and a lumped kinetics model based on the competitive adsorption of long vs. short chains reveal that the activity of catalytic material is highest with the smallest NPs, consistent with a structure-sensitive reaction. Remarkably, the three mSiO₂/Pt-X/SiO₂ catalysts give equivalent selectivity. We propose that mesoscale pores in the catalytic architecture template the C₂₃-centered distribution, whereas the active Pt sites influence the carbon-carbon bond cleavage rate. This conclusion provides a framework for catalyst design by separating the C-C bond cleavage activity at catalytic sites from selectivity for chain lengths of the products influenced by the structure of the catalytic architecture. The increased activity, selectivity, efficiency, and lifetime obtained using this architecture highlight the benefits of localized and confined environments for isolated catalytic particles under condensed-phase reaction conditions.

Huang, Lei published the artcileTuning the Electron Density of Metal Nickel via Interfacial Electron Transfer in Ni/MCM-41 for Efficient and Selective Catalytic Hydrogenation of Halogenated Nitroarenes, COA of Formula: C6H17NO3Si, the publication is ACS Sustainable Chemistry & Engineering (2022), 10(9), 2947-2959, database is CAplus.

Catalytic hydrogenation of nitrocompound is an environment-benign strategy for the production of important aniline intermediates. Herein, MCM-41 was synthesized from sepiolite via in situ self-assembled method and the modified MCM-41 supported nickel-based catalysts were prepared and applied in halogenated nitrobenzene hydrogenation to halogenated aniline. Compared with Ni/MCM-41, the Sn or La modified MCM-41 supported nickel-based catalysts exhibited better catalytic performance. The electron transfer from Sn or La species to Ni led to a downshift in d-band center of Ni, which was in favor of H desorption and hence promoted hydrogenation activity. It was found that chloronitrobenzene preferred the tilted adsorption orientation mode on the surface of Ni-Sn and Ni-La₂O₃ to flat adsorption orientation. Moreover the C-Cl bond scission on Ni-Sn and Ni-La₂O₃ were thermodynamically unfavorable in comparison with pure-phased Ni, leading to higher selectivity to chloroaniline. Ni/LaMCM-41-NH₂ gave the best catalytic performance of 100% conversion and 99.6% selectivity to m-chloroaniline.

We prepared high-mol.-weight block copolymers (BCPs) composed of polystyrene (PS) brush blocks and polyhedral oligomeric silsesquioxane (POSS)-tethered polynorbornenes with variable composition ratios. By changing the substituents at the vertex of POSS from iso-Bu groups to cyclopentyl ones, we evaluated the substituent effect on structural color and thermal stability against annealing. The BCPs modified with iso-Bu groups showed clear structural color, while color changes were observed after annealing. By replacing to cyclopentyl groups, structural color was also presented, and improvement of thermal resistance was observed by heating. From the series of thermal analyses, it was proposed that thermal enhancement of cyclopentyl-substituted POSS domains could be responsible for the improvement of thermal stability of structural color.

Zandi-Mehri, Elham published the artcileDesigning of hydroxyl terminated triazine-based dendritic polymer/halloysite nanotube as an efficient nano-adsorbent for the rapid removal of Pb(II) from aqueous media, Computed Properties of 13822-56-5, the publication is Journal of Molecular Liquids (2022), 119407, database is CAplus.

In the present study, the hydroxyl terminated triazine-based dendritic polymer was synthesized and grown on the halloysite nanotubes surface (HNT-G2) to efficiently remove the Pb(II) ions from aqueous solution The nano-adsorbent morphol. and structure were determined through TEM (transmission electron microscope), XRD (X-ray diffraction), FT-IR (Fourier transformation infra-red), TGA (thermogravimetry anal.), BET (Brunauer-Emmet-Teller) isotherm, and EDS (energy dispersive anal. X-ray spectroscopy) methods. The adsorption of Pb(II) resulted a maximum of 75.2 mg/g at 298 K at optimal pH 6 after only 10 min and 2 g/L of HNT-G2. The adsorption kinetic revealed that it followed the pseudo-second-order model while the adsorption isotherms corresponded the Langmuir model. Accordingly, it could be inferred that the Pb(II) was a single-layer adsorption occurring on the adsorbent surface and further, the rate-controlling step was denoted chem. adsorption. Also, the thermodn. outcome indicated that the adsorption progress could happen spontaneously, and was of the exothermic reaction types (¦¤H = -79.99 kJ/mol and ¦¤G = -7.90 kJ/mol). Surprisingly, the adsorption and desorption efficiency after four cycles was high, while the Pb(II) adsorption mechanism affecting the adsorbent was basically via chelation through the O atoms. Hence, it can be concluded that the HNT-G2 was an effective in efficiently elimination of Pb(II) from the aqueous solution, having high applicability significance.
