Macroporous Biphasic Calcium Phosphate Scaffolds Reinforced by Poly-L-lactic acid/Hydroxyapatite Nanocomposite Coatings for Bone Regeneration
Three-dimensional
(3D) interconnected porous scaffolds with biomimetic hierarchical architectures
and mechanical characteristics are critical for the success of bone
regeneration. In this paper, biphasic calcium phosphate (BCP) scaffolds were
coated with medical-grade poly-L-lactic acid/hydroxyapatite
(mPLLA/HA) nanocomposites to create controlled surface roughness while
remaining the interconnect...

[Macromol. Rapid Commun.] pH- and Sugar-Induced Shape Memory Hydrogel Based on Reversible Phenylboronic Acid-Diol Ester Bonds
A simple strategy is provided to construct a novel pH and sugar-induced
shape memory hydrogel based on the dynamic phenylboronicacid-diolinteractions formed
byphenylboronic acid modified sodium alginate (Alg-PBA) and poly(vinyl
alcohol)(PVA). The dynamic PBA-diol ester bonds would serve as temporary
crosslinks and stabilize the deformed shape of the hydrogel.The disassociation
of the PBA-diol este...

[Langmuir] Synthesis and properties study of the uniform nonspherical styrene/methacrylic acid copolymer latex particles
A facile method to prepare the nonspherical amphiphilic random copolymer of poly(styrene-co-methacrylic acid) (poly(St-co-PMAA)) latex particles with well-defined shapes and high yields by one-step batch emulsifier-free polymerization was demonstrated. In our strategy, only varying the molar ratio of styrene (St) to methacrylic acid (MAA), no seed-particles, no cross-linker and no multi-step contr...

209. Polydopamine-coated electrospun poly(vinyl alcohol)/poly(acrylic acid) membranes as efficient dye adsorbent with good recyclability.
Free-standing poly(vinyl alcohol)/poly(acrylic acid) (PVA/PAA) membranes with polydopamine (PDA) coating were prepared based on the combination of electrospinning and self-polymerization of dopamine. This is a facile, mild, controllable, and low-energy consumption process without any rigorous restriction to reactive conditions. Benefiting from the high specific surface area of electrospun membrane...

Preparation and characterization of nanocrystalline cellulose via low-intensity ultrasonic-assisted sulfuric acid hydrolysis
Nanocrystalline cellulose (NCC) was extracted from microcrystalline cellulose via low-intensity ultrasonic-assisted sulfuric acid hydrolysis process. NCC samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), particle size distribution (PSD) analysis, Fourier-transformed infrared spectra (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis...

Reuse of acid coagulant-recovered drinking waterworks sludgeresidual to remove phosphorus from wastewater
Acid coagulant-recovered drinking waterworks sludge residual (DWSR) is a waste product from drinking waterworks sludge (DWS) treatment with acid for coagulant recovery. In this study, we evaluated DWSR as a potential phosphorus (P) removing material in wastewater treatment by conducting a series of batch and semi-continuous tests. Batch tests were carried out to study the effects of pH, initi...

A facile route to the synthesis of spherical poly(acrylic acid) brushes via RAFT polymerization for high-capacity protein immobilization
Spherical poly(acrylic acid) brushes were prepared via a facile RAFT polymerization route from silica nanoparticles (SiO2@PAAs). A silane functionalized RAFT chain transfer agent was designed and synthesized by a one-step reaction, and then immobilized onto silica nanoparticles (SiNPs) through its R group to afford RAFT polymerization. Key structural parameters and contents of carboxyl groups of...

Covalent Immobilization of Proteins on 3D Poly (acrylic acid) Brushes: Mechanism Study and a More Effective and Controllable Process
Polymeric brushes have emerged as a novel 3D material platform that provides great amounts of binding sites for biomolecules. This paper investigates the covalent immobilization mechanism of protein by spherical poly(acrylic acid) brushes (SPAABs) in the widely adopted N-hydroxysuccinimide / N-(3-dimethyl- aminopropyl)-N’-ethylcarbodiimide hydrochloride (NHS/EDC) process. It was discovered that...
