Green and scalable fabrication of core-shell bio-based flame retardants for reducing flammability of polylactic acid
The design of flame-retardant biocomposites based on biobased flame retardants (FRs) represents a promising direction for creating a sustainable world. To date, it remains a major challenge to explore a green and calable strategy for the design of highly effective, biobased FRs for bioplastics, such as polylactic acid (PLA). Herein, we have demonstrated a green, facile fabrication approach for a...

Biodegradable UV-Blocking Films through Core–Shell Lignin–Melanin Nanoparticles in Poly(butylene adipate-co-terephthalate).
Biodegradable and renewable UV-shielding films are highly demanded to meet the increasing sustainable requirement for the environment. Lignin as a natural broad UV blocker has gained considerable attention; however, the poor dispersibility within synthetic polymers limited its applications. Thus, a bioinspired melanin-like polydopamine thin layer was incorporated for the first time with lignin n...

Controlling the Core-Shell Structure of CuS@CdS Heterojunction via Seeded Growth with Tunable Photocatalytic Activity
We report the seed-mediated synthesis of CuS@CdS core-shell heterojunction with diverse morphologies by introducing kinetic control.By using CuS nanoplates as seeds and a collective manipulation of the injection rate of Cd2+ precursor with a syringe pump and the reaction
temperature, two distinctive growth modes, i.e., island and layer-by-layer modes, respectively, could be realized. It is fo...

SiO2/carbon composite microspheres with hollow core-shell structure as high stability electrode for lithium ion batteries.
The SiO2/carbon composite material used as a lithium‐ion battery (LIB) anode was synthesized by aerosol spraying a mixture of polyvinyl alcohol (PVA) solution and SiO2nanoparticles, followed by coating polyacrylonitrile (PAN) on the SiO2/PVA surface and an annealing treatment at 800?°C. The as‐prepared SiO2/po‐C@C has a hollow core–shell structure. The hollow section contributes to accommodat...

Low-cost water caltrop shell-derived hard carbons with high initial coulombic efficiency for sodium-ion battery anodes.
Hard carbon possesses excellent properties of sodium storage, but high cost and low initial coulombic efficiency significantly affect the anode in large-scale application of sodium-ion batteries (SIBs). Here, we first report the waste water caltrop shell-derived hard carbons prepared by facile pyrolysis and subsequent an acid treatment. With the dense structure, low specific surface area and large...

Enhancing mechanical performance of epoxy thermosets: Via designing a block copolymer to self-organize into "core-shell" nanostructure
ABSTACT: A rigid-flexible amphiphilic pentablock copolymer, polystyrene-block-poly(3-caprolactone)-blockpolydimethylsiloxane-block-poly(3-caprolactone)-block-polystyrene (PS-PCL-PDMS-PCL-PS, SLDLS), was designed. SLDLS block copolymers will self-organize into “core–shell” nanostructures in epoxy thermosets, with rigid PS as the “shell” and flexible PDMS as the “core”. Due to the incorpora...

Polymeric Microcapsules with Sustainable Core and Hierarchical Shell toward Superhydrophobicity and Sunlight-Induced Self-Healing Performance
Photopolymerization is considered as one of most promising candidates for microcapsules-embedded self-healing system due to its significant advantages, e.g., fast, energy efficient and commonly economical. However, many microencapsulated photopolymerizable healing agents are usually expensive, unsustainable, or even environmentally hazardous. Herein, a polymeric microcapsule with hierarchical shel...

Dual tuning of 1 D heteroatoms doped porous carbon nanoarchitectures for supercapacitors: the role of balanced P/N doping and core@shell nanonetworks
Heteroatoms dual-doped carbon with three dimensional interconnected architecture is a promising candidate as electrode for high performance energy storage, but the rational design and cost-effective preparation of such materials is still a challenge. Herein, intriguing P and N co-doped porous CNT@carbon core@shell nano-networks (PN-CNTs) have been facilely achieved by a one-step carbonization pr...

Cobalt-carbon core–shell nanoparticles aligned on wrinkle of N-doped carbon nanosheets with Pt-like activity for oxygen Reduction
A one-step soft-template induced strategy is demonstrated for the controlled synthesis of nitrogen-enriched core-shell structured cobalt-carbonnanoparticles (NPs) sequentially aligned on wrinkles of N-doped carbon nanosheets (Co-C@NWCs). The key feature of Co-C@NWCs for ORR catalysis enhancement is that it combines high catalytic centers of Co-C core-shell NPs with the wrinkle of carbon nanoshee...
