Flexible polymer composite films are prepared by a solution cast method with polar polyvinylidene fluoride (PVDF) or non-polar epoxy as the matrix. BaTiO3 nanoparticles and nanofibers large aspect ratio used dielectric fillers after surface modification polydopamine. The effects of filler shape, polarity matrix on microstructure, constants breakdown strength composites investigated in detail. Surface polydopamine improves compatibility between well passivating surfaces BaTiO3. At same volume...
BaTiO3 nanofibers with a large aspect ratio prepared via electrospinning and modified by dopamine were used as dielectric fillers in poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE)-based nanocomposites. Highly flexible polymer nanocomposite films fabricated simple solution-cast method. Enhanced permittivities obtained at low volume fraction of nanofibers. The breakdown strength the nanocomposites was also improved, which is favorable for enhanced ferroelectric properties Pr ∼9.1 μC...
By using Bi2O3-doped Ba0.3Sr0.7TiO3 (BSBT) fibers prepared via electrospinning and modified by dopamine as dielectric fillers, BSBT/P(VDF-TrFE) flexible nanocomposites are fabricated solution casting. A low loading of BSBT nanofibers leads to a large increase in the constant breakdown strength. In particular, discharged energy density is significantly enhanced several times comparison with pure polymer matrix. The strength could be attributed combined effects surface modification, aspect...
Ba0.6Sr0.4TiO3 (BST) nanofibers prepared via electrospinning and modified by dopamine are used as dielectric fillers in polyvinylidene fluoride (PVDF)-based composites. With 4.4 vol. % of BST nanofibers, the extractable energy density BST/PVDF composites is more than doubled compared with pure PVDF matrix. Such significant enhancement attributed to combined effect both surface modification large aspect ratio nanofibers. Paraelectric or anti-ferroelectric may serve a general strategy for...
In recent years, interest in magnetic biomimetic scaffolds for tissue engineering has increased considerably. The aim of this study is to develop biodegradable fibrous materials with potential use bone regeneration. Magnetic Fe3O4/chitosan (CS)/poly vinyl alcohol (PVA) nanofibrous membranes were achieved by electrospinning average fiber diameters ranging from 230 380 nm and porosity 83.9–85.1%. influences polymer concentration, applied voltage Fe3O4 nanoparticles loading on the fabrication...
Phase-change heat transfer on nanostructured surfaces is an efficient cooling method for high flux devices due to its superior wettability. Liquid droplet spreading and wicking effect then dominate the transfer. Therefore, this study investigates flow behavior after a touches surface focusing ZnO nanowire with three different sizes two array types (regular irregular). The diameter are measured against time. results show that average velocities regular both smaller than those irregular size...
Suitable material for scaffolds that support cell attachment, proliferation, vascularization and contraction has always been a challenge in myocardial tissue engineering. Much research effort focused on natural polymers including collagen, gelatin, chitosan, fibrin, alginate, etc. Among them, collagen/chitosan composite scaffold was widely used Due to the non-proliferative contractile characteristics of cardiomyocytes, biocompatibility mechanical properties are extremely important supporting...
The worldwide increase in antibiotic-resistant pathogens means that identification of alternative antibacterial drug targets and the subsequent development new treatment strategies are urgently required. One such target is quorum sensing (QS) system. Coral microbial consortia harbor an enormous diversity microbes, thus rich sources for isolating novel bioactive pharmacologically valuable natural products. However, to date, versatility their compounds has not been broadly explored. In this...

Abstract As a promising anode material for lithium‐ion batteries, Si is still facing great challenges owing to the rapid capacity fade, which mainly caused by large volume changes during cycling. We have rationally designed novel 3D porous carbon–silicon frameworks self‐assembly of phenol formaldehyde resin and triblock copolymer. The copolymer acts as both structure‐directing agent template formation uniform carbon shell generation bimodal structures. as‐fabricated (PC–Si) hybrid exhibits...

In tissue engineering studies, scaffolds play a very important role in offering both physical and chemical cues for cell growth regeneration. However, some cases, regeneration requires with high mechanical properties (e.g., bone cartilage), while cells need soft microenvironment. this study, to mimic the heterogenous of spinal cord tissue, biomimetic rat construct is fabricated. A collagen-coated poly(lactic-co-glycolic acid) scaffold manufactured using thermally induced phase separation...
Abstract Hydrogels are characterized by high water content and typically used in environments. However, when air environments, hydrogels face limitations due to instability caused loss.

The hydrogel made forming single PAM crosslinking network UV crosslinked acrylamide (AM) monomer. weight varied...
For tissue engineering and regenerative medicine, creating thick heterogeneous scaffold-based constructs requires deep precise multicellular deposition. Traditional cell seeding strategies lack the ability to create with high penetration distribution, while emerging aim simultaneously combine cell-laden segments scaffold fabrication.
