[Journal of the European Ceramic Society] Additive manufacturing of green ceramic by selective laser gasifyingof frozen slurry
The slurry-based additive manufacturing (AM) of ceramics involves a drying process to form solid support; however, the drying process is time-consuming, and the support is not easily removed. We propose a new AM process for green ceramic that includes freezing a layer of aqueous ceramic slurry, laser gasifying of the frozen-layer ice to process 2D green ware, and removing the support in water to...

Green Poly(β-hydroxybutyrate)/Starch Nanocrystal Composites: Tuning the Nucleation and Spherulite Morphology through Surface Acetylation of Starch Nanocrystal
Carbohydrate Polymers, 2018, 195C, 79-88.
ABSTRACT:
Starch nanocrystal (SNC) particles were used as the filler to prepare green composites with biodegradable poly(β-hydroxybutyrate) (PHB). An interesting way to tune the nucleation and banded morphology of composites by the surface acetylation of SNC was proposed. Pristine SNC acts as the nucleating agent, while acetylated...

Crystallization of Green Poly(ε-caprolactone) Nanocomposites with Starch Nanocrystal: The Nucleation Role Switching of Starch Nanocrystal with Its Surface Acetylation
Industrial & Engineering Chemistry Research, 2018, 57(18), 6257-6264.
ABSTRACT:
Poly(ε-caprolactone) (PCL) was filled with very small amount of starch nanocrystals (SNC), with the objective to control its crystallization. Three kinds of SNC particles, including the pristine one and the acetylated ones with low-level and middle-level substitutions, were used. Their roles acted d...

Green Poly(epsilon-caprolactone) Composites Reinforced with Electrospun Polylactide/Poly(epsilon-caprolactone) Blend Fiber Mats
As two typical aliphatic polyesters, biodegradable poly(ε-caprolactone) (PCL) and polylactide (PLA) show quite different mechanical properties. Compounding them together is therefore an interesting topic on the fabrication of biomaterials with tailorable properties. The composite technology was used in this work to prepare a new PCL/PLA system, the green PCL composites reinforced with the electro...

Green Nanocomposites Based on Functionalized Cellulose Nanocrystals: A Study on the Relationship between Interfacial Interaction and Property Enhancement
Functionalized cellulose nanocrystals (PHCNs) were synthesized by grafting poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) onto cellulose nanocrystals (CNCs). The resultant PHCNs with high loading levels were uniformly dispersed into a PHBV matrix to produce fully biodegradable nanocomposites, which showed superior mechanical performance and thermal stability. Compared with those of neat PHBV,...

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...

Cellulose nanocrystals as green fillers to improve crystallization and hydrophilic property of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
The green nanocomposites of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with various cellulose nanocrystals (CNCs) contents were prepared by solution casting method. The effects of CNCs on the crystallization behavior, spherulitic morphology, crystal structure and hydrophilic property of PHBV were studied by differential scanning calorimeter (DSC), polarized optical micro...

A Green Strategy to Enhance a Liquid-Liquid Heterogeneous Reaction with a Magnetic Recyclable Pickering Emulsion
This work described a general strategy to enhance a typical organic-aqueous heterogeneous green oxidation reaction by introducing surface tunable magnetic nanoparticles into liquids to form a controllable Pickering emulsion. We synthesized cross-linked polystyrene (PS)-covered Fe3O4 nanoparticles grafted with different N-alkyl imidazoles and systematically discussed the effect of surface propertie...

Effective Electron Transfer between Heteropoly Blue and Graphene Oxide: A Green Approach to Graphene Synthesis
A facile electrochemical approach for the synthesis of graphene is developed by highly effective electron transfer from electron-rich heteropoly blue to graphene oxide. Reduced graphene oxide immobilized on a glassy carbon electrode (GCE) shows more positive potential for hydrogen evolution owing to the presence of the polyoxometalate electrocatalyst.
