Multisite Captured Copper Ions via Phosphorus Dendrons Functionalized Electrospun Short Nanofibrous Sponges for Bone Regeneration (Adv. Funct. Mater. 5/2023)

Abstract

Electrospun Short Nanofibrous Sponges In article number 2211237, Xiaoji Luo, Wenguo Cui, Wei Huang, and co‐workers construct the biomimetic electrospun short nanofibrous sponges functionalized with phosphorus dendrons with the function of loading and multisite capturing free copper ions to realize the integrated repair of vascularization and bone regeneration by promoting osteogenic differentiation of bone marrow mesenchymal stem cells and angiogenesis of human umbilical vein endothelial cells.

Geometric Angles and Gene Expression in Cells for Structural Bone Regeneration

“…The ability of scaffolds to promote vascular formation plays an important role in bone regeneration because neovascularization can accelerate bone repair by delivering nutrients and oxygen to the site of injury. [ 14 ] The ability of various fibers to induce vascularization was studied via reverse transcription‐quantitative real‐time polymerase chain reaction (qRT‐PCR) and western blotting. As shown in Figure 2D, the VEGF and CD31 expression in the fiber groups was significantly higher than that in the control group ( P < 0.01), however, there was no significant difference between the fiber groups.…”

A novel 1D/2D core/shell CdS@SnS2 heterostructure for efficient piezocatalytic hydrogen evolution and pollutant degradation

“…In this case, the piezoelectric eld will make electrons and holes transfer in opposite directions, thereby effectively inhibiting their recombination and allowing more free carriers to be enriched on the catalyst surface to participate in the piezocatalytic reactions. [47][48][49] Moreover, as revealed by the XPS results, the potential internal electric eld is also benecial for the transfer of electrons and holes mentioned above. As a result, the piezocatalytic performance of the CdS@SnS 2 heterojunction is markedly superior to that of single components.…”

Organic piezocatalyst polyimide: molecular structure tailoring and robust built-in electric field

“…7a. 44 Compared with PM-1 and PM-2, PM-3 holds the largest effective piezoelectric coefficient (9.05 pm V −1 ), which means it exhibits the strongest piezoelectric polarization. It has been conrmed that the catalyst with a higher piezoelectric response could induce a stronger piezoelectric eld, thus immensely promoting piezocatalytic activity under an external mechanical force.…”
