The bio-inspired approach to controllable biomimetic synthesis of silver nanoparticles in organic matrix of chitosan and silver-binding peptide (NPSSLFRYLPSD)
Inspired by organic matrices in some life systems which can operate as templates for biosynthesis organic materials with uniform size and morphology, in our experiment, chitosan was combined with AG4 peptide (NPSSLFRYLPSD) to form a simple organic matrix, which was used as a template to synthesize particle size and morphology-controlling silver nanoparticles. The results of UV-vis determinati...

[ACS Appl. Mater. Interfaces] Ligand-Induced Tunable Dual-Color Emission Based on Lead Halide Perovskites for White Light-Emitting Diodes
Cesium lead halide perovskites (CsPbX3, X = Cl, Br, and I) have emerged as an important class of colortunable light-emitting materials in the past 4 years. However, single-CsPbX3 nanostructures with dual-color emission remain scarce. Here, we demonstrate dual-color emission from lead halide perovskite nanowires induced by the surface ligands, that is, oligomeric methoxypolyethylene glycol (MEOPE...

[ACS AMI] Micro-/Macroscopically Synergetic Control of Switchable 2D/3D Photothermal Water Purification Enabled by Robust, Portable and Cost-effective Cellulose Papers
Solar energy, as a renewable and sustainable resource, is considered to be a promising
candidate for solving the water shortage through an interfacial solar-to-thermal conversion. Despite tremendous advances are achieved, it is still challenging for limited size, high-cost and complicated fabrication protocols. More importantly, a favorable 2D/3D structure transformation to adapt to diverse c...

（ACS Appl. Mater. Interfaces）2D-to-3D Shape Transformation of Room-Temperature- Programmable Shape-Memory Polymers through Selective Suppression of Strain Relaxation
Although shape-memory polymers (SMPs) can alter their shapes upon stimulation of environmental signals, complex shape transformations are usually realized by using advanced processing technologies (four-dimensional printing) and complicated polymer structure design or localized activation. Herein, we demonstrate that stepwise controlled complex shape transformations can be obtained from a single...

[ACS Sustainable Chem. Eng.]Efficient and Green Fabrication of Porous Magnetic Chitosan Particles Based on a High-Adhesive Superhydrophobic Polyimide Fiber Mat
In this paper, an efficient and green strategy was developed to synthesize porous magnetic chitosan (PMCS) particles via a special superhydrophobic effect of a porous fluorinated polyimide (PFPI) fiber mat with a petal effect. By controlling the fiber morphology and porous structures on the fiber surface, the water contact angle on the fiber mat reached as high as 155.3° and the adhesion to a w...

【36 ACS Sustainable Chemistry & Engineering】 Sustainable conversion of mixed plastics into porous carbon nanosheet with high performances in uptake of carbon dioxide and storage of hydrogen
Conversion of waste plastics into high value-added carbon nanomaterials has gained wide research interest due to the requirement of sustainable development and the ever-increasing generation of waste plastics. However, most of studies are limited to single component plastic; besides, little attention has been paid to carbon nanosheets (CNS). Herein, CNS were prepared by catalytic carbonization of ...

ACS Sustainable Chemistry & Engineering——Co-depositing mussel-inspired nanohybrids onto 1D fibers under “green” conditions for significantly enhanced surfacial/interfacial properties
Co-deposition of mussel-inspired nanohybrid coating was realized onto carbon fiber (CF) surface via co-incubation in the dopamine (DA) and octaammonium polyhedral oligomeric silsesquioxane (POSS-NH2) mixed aqueous solution. The deposition procedure was conducted under ambient conditions, and no harsh conditions and toxic solvents were needed. The surface morphology, compositions, and energies of C...
