A facile one-pot route for preparing cellulose nanocrystal/zinc oxide nanohybrids with high antibacterial and photocatalytic activity
Cellulose nanocrystal/zinc oxide (CNC/ZnO) nanohybrids were prepared through citric acid/hydrochloric acid hydrolysis of commercial microcrystalline cellulose (MCC), and simple precipitation with zinc nitrate aqueous solution [Zn(NO3)2·6H2O] via one-pot green synthesis, in which preparation and modification of CNCs were performed simultaneously and the obtained CNCs with carboxyl groups cou...

One-pot green fabrication and antibacterial activity of thermally stable corn-like CNC/Ag nanocomposites
Corn-like cellulose nanocrystals/silver (CNC/Ag) nanocomposites were prepared by formic acid/hydrochloric acid hydrolysis of commercial microcrystalline cellulose (MCC), and redox reaction with silver ammonia aqueous solution (Ag(NH3)2(OH)) in one-pot green synthesis, in which the preparation and modification of CNCs were performed simultaneously and the resultant modified CNCs could be as reducin...

One-step extraction and functionalization of cellulose nanospheres from lyocell fibers with cellulose II crystal structure
Functionalized cellulose nanospheres (spherical nanocellulose formates, SCNFs) were extracted by one-step HCOOH/HCl hydrolysis of lyocell fibers with cellulose II crystal structure. The as-prepared cellulose nanoparticles were characterized by field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Fourier transfor...

One-pot facile synthesis of branched Ag-ZnO heterojunction nanostructure as highly efficient photocatalytic catalyst
In this paper, the branched Ag-ZnO heterojunction nanostructure and the branched ZnO were synthesized successfully by a facile, green and one-pot hydrothermal method. Such branched heterojunction and the comparing branched pure ZnO were characterized by X-ray diffraction, field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), energy-dispersiv...

One-step fabricated wettable gradient surface for controlled directional underwater oil-droplet transport.
A wettable gradient surface for underwater oil is fabricated by a one-step anodic oxidation method on a graphite plate and self-propulsion of an underwater oil droplet is achieved on it. Moreover, the transport distance could be further controlled and predicted via the initial position of the droplet and/or tilted angle of the graphite plate. Such surfaces with a continuous wettable gradient for...

Antibacterial cellulose membrane via one-step covalent immobilization of ammonium/amine groups
This work describes a direct covalent linking of quaternary ammonium salts (QAS) and aminoalkyl groups onto regenerated cellulose (RC) membrane surface to prepare contact active antibacterial membrane materials. The membranes were prepared via alkoxysilane polycondensation reaction with three silane coupling agents, including trimethoxysilylpropyl trimethyl ammonium chloride (QASC0), trimethoxys...

One-step synthesis of PHEMA hydrogel films capable of generating highly ordered wrinkling patterns
Poly(2-hydroxyethyl methacrylate) (PHEMA) films with gradient crosslinking density are the only hydrogel films capable of generating regular wrinkling patterns upon swelling, however, they were synthesized via a complicated two-stage photopolymerization. In an effort to develop a simple synthesis method, we found that one-step UV-curing of HEMA liquid always results in films with corrugated surf...

RAFT-Polymerization-Induced Self-Assembly and Reorganizations: Ultrahigh-Molecular-Weight Polymer and Morphology-Tunable Micro-/Nanoparticles in One Pot.
A one-pot method is introduced for the successful synthesis of narrow-distributed (D = 1.22) vinyl polymer with both ultrahigh molecular weight (UHMW) (M-w = 1.31 x 10(6) g mol(-1)) and micro-/nanomorphology under mild conditions. The method involves the following four stages: homogeneous polymerization, polymerization-induced self-assembly (PISA), PISA and reorganization, and PISA and multiple ...

[J. Mater. Chem. B]One-step synthesis of glycoprotein mimics in vitro: improvement of protein activity, stability and application in CPP hydrolysis
Glycopolymer–protein biomimetic materials have been receiving considerable attention in various biomedical and pharmaceutical studies and applications. However, owing to the easily induced inactivation of protein and the complexity of preparation, efficient in vitro synthesis of highly active and stable glycopolymer–protein conjugates is considerably difficult. Here, an ideal and facile one-step...

[Polym. Chem.] Fe(0) powder-catalyzed one-pot reaction: concurrent living radical polymerization and click chemistry for topological polymers
Fe(0) powder-catalyzed one-pot reaction was successfully employed to design linear and star polymers in a well-controlled manner by combining ambient temperature living radical polymerization and click chemistry. The polymerization behavior possessed the characteristics of “living”/controlled radical polymerization: the first-order kinetic plots, narrow molecular weight distribution (PDI < ...
