Ethylene-octene copolymer (EOC) with a loading level of 20 wt%, maleated EOC (EOC-g-MA) 3 wt% and graphene nanoplatelets (GnPs) at four different levels, i.e., 5 10 15 were added to nylon 6 prepare nanocomposites using twin-screw extruder high shear rate screw running 300 rpm. Increased stiffness was observed the addition GnPs while tensile strength only slightly influenced. Addition into 6/EOC...

The molybdenum-based monoaryloxide monopyrrolide (MAP) species, Mo(NAd)(CHCMe(2)Ph)(C(4)H(4)N)(HIPTO) (2a), which contains "small" imido (Ad = 1-adamantyl) and "large" aryloxide (HIPTO = O-2,6(2,4,6-i-Pr(3)C(6)H(2))C(6)H(3)) ligands, catalyzes Z-selective metathesis reactions as a consequence of intermediate metallacyclobutane species not being able to have an (anti) substituent pointing toward...

For the aromatization of olefins (in Fischer–Tropsch synthetic oil), especially for fluidized bed reaction with steam as medium, improving catalytic and hydrothermal stabilities ZSM-5 catalysts is a research focus because both fundamental interests potential commercial applications. In this work, sequential alkali treatment phosphorus modification were carried out samples. The results obtained ...

The aromatization of 2-octanol derived from castor oil as a byproduct in the formation of sebacic acid was investigated on various zeolite catalysts. Zn ion-exchanged MFI (ZSM-5) zeolites with small silica/alumina ratios and zinc contents of 0.5 to 2.0 wt. % were determined to exhibit good and stable activity for the reaction at 623 to 823 K. The yield of aromatics was 62% at 773 K and the spac...

Neutral Zr(IV) and Hf(IV) dimethyl complexes stabilized by unsymmetrical dianionic {N,C,N'} pincer ligands have been prepared from their corresponding bis-amido complexes upon treatment with AlMe₃. Their structure consists of a central ó-bonded aryl donor group (C) capable of forming robust M-C bonds with the metal center, enforced by the synergic effect of both the coordination of peripheral d...

Protein engineering has shown widespread use in improving the industrial application of enzymes and broadening conditions they are able to operate under by increasing their thermostability solvent tolerance. Here, we show that protein can be used increase an artificial metalloenzyme. Thermostable variants human steroid carrier 2L, modified bind a metal catalyst, were created rational design usi...

Recent advances in the characterization of ethylene/1-octene-based statistical multiblock copolymers (MBCs) synthesized via chain shuttling copolymerization are illustrated. The Perspective focuses on peculiarity MBC systems that consists nonuniform architecture these intriguing due to compositional heterogeneity occurring at inter- and intra-chain level. In first part, effect dispersity phase ...
