A new approach has been developed to fabricate tough hybrid hydrogels by employing dual enzyme-mediated redox initiation to achieve post-self-assembly cross-linking polymerization. The resulting hydrogel combines the merits of supramolecular hydrogels with polymeric hydrogels to achieve higher mechanical strength and porous networks. Designed 3D constructs were fabricated via in situ 3D printin...

Solid-State Lithium Batteries In article number 2201762, Maoxiang Jing, Xiangming He, and co-workers report a composite solid-state electrolyte (CSE) formed by in-situ polymerization of 1.3-dioxolane (DOL) catalyzed nano yttria stabilized zirconia. Excellent cycle stability provides new research idea for the practical application PDOL based CSE at high voltage.

Polymer filling of the air holes of Indium Phosphide based two-dimensional photonic crystals is reported. After infiltration of the holes with a liquid monomer and solidification of the infill in situ by thermal polymerization, complete filling is proven using scanning electron microscopy. Optical transmission measurements of a filled photonic crystal structure exhibit a redshift of the air ban...

This review summarizes recent developments in the field of enantiomer separation by capillary electrochromatography using fritless packed columns. Various enantiomers have been separated by employing fritless packed columns prepared in a fused silica capillary either by the immobilization of chiral packing materials by sintering or sol-gel technology or by in situ polymerization of a mixture co...

Bifunctional Ag(I), Pd(II), Rh(I), Ru(II) and Au(I) complexes containing a NHC ligand and a pendant trivalent boron moiety have been synthesized in high yields. Fine-tuned reaction conditions were used to prevent potential ligand self-quenching or polymerization due to the eventual co-existence in situ of free NHC (Lewis base) and boronic ester (Lewis acid) in the same molecule.

This chapter describes the details of the synthesis of polyaniline (PAni) nanofiber reinforced polyvinyl alcohol (PVA) nanocomposites employing in-situ rapid mixing polymerization technique and the effect of SHI irradiation on the physico-chemical properties of the nanocomposites. Modifications in the morphology, conformation and the charge transport properties of the nanocomposites have been i...

Polydopamine-derived carbon (C-PDA) nanospheres embedded with zinc ferrite (ZnFe2O4) are synthesized by in situ polymerization of dopamine with zinc and iron species followed by carbonization. The composite nanospheres contain ZnFe2O4 nanoparticles ∼8 nm in size well dispersed in porous C-PDA. The unique structure and morphology endow the nanospheres with excellent rate capability and cycling s...

Some of the most active catalysts for carbon dioxide and epoxide copolymerization are dinuclear metal complexes. Whilst efficient homodinuclear catalysts are known, until now heterodinuclear catalysts remain unreported. Here, a facile, in situ route to a catalyst system comprising a mixture of homo- and heteronuclear Zn-Mg complexes is presented. This catalyst system shows excellent polymerizat...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene maleic anhydride copolymer (SMA), and the addition...

A novel one-step synthetic route, the double in situ approach, is used to produce both TiO(2) nanoparticles and polymer (PET), and simultaneously forming a nanocomposite with multi-functionality. The method uses the release of water during esterification to hydrolyze titanium (IV) butoxide (Ti(OBu)(4)) forming nano-TiO(2) in the polymerization vessel. This new approach is of general significanc...
