Magnesium-based biodegradable alloys exhibit excellent mechanical properties and bioactivity, which are favorable in the orthopedic applications. In addition, degradation of Mg results an alkaline microenvironment can effectively withstand bacteria. However, rate is too fast to sustain healing process. And enhancement its corrosion resistance may compromise antibacterial ability, thus, alloying with elements or doping these into coatings on be a prospective strategy combine activity...
Micro-arc oxidation (MAO) treatment is a simple and effective technique to improve the corrosion resistance for magnesium alloys. However, presence of micro-pores cracks on coatings provides paths corrosive ions penetrate into react with substrate, limiting long-term resistance. In this paper, we designed composite coating which GelMA hydrogel varying thicknesses were prepared surface MAO-coated alloys via dip-coating method, aiming biocorrosion biocompatibility. The morphology, chemical...
Abstract Optical gains at 637 nm wavelength using light‐emitting diodes (LEDs) instead of traditional semiconductor lasers as pumping sources are demonstrated in the organic molecule 2,6‐bis[4‐(diphenylamino)phenyl]‐9,10‐anthracenedione (AQ(PhDPA) 2 )‐doped polymethylmethacrylate (PMMA) and SU‐8 polymer waveguides. Under excitation four blue‐violet LEDs with different central wavelengths, fluorescence red band is observed owing to transition AQ(PhDPA) from excited states ground state based...
Based on the phase separation phenomenon in micro-droplets, polymer-lipid Janus particles were prepared a microfluidic flow focusing chip. Phase of droplets was caused by solvent volatilization and morphology formed under action interfacial tension. Because change from solid to liquid lipid hemisphere could be triggered physiological temperature, used for rapid release drugs. While polymer we selected pH sensitive that degrade acidic conditions, making it possible drugs specific environment,...
We report a method of using neodymium complexes as active waveguide core materials to achieve optical gain at the 1060 nm wavelength when an LED instead 808 semiconductor laser pump source. Through intramolecular energy transfer mechanism between ligands and Nd 3+ ions, photoluminescence spectrum could be obtained on 100µm thick film complex doped PMMA polymer under excitation 380 nm-450 LED. also present calculations showing that power required generate (turn-on power) for is 3.3 mW 40 mW,...
In this paper, a polymer waveguide sensor based on localized surface plasmon resonance (LSPR) of gold nanoparticles was demonstrated. Gold with diameter 20 nm were synthesized. Polymer SU-8 3050 material used as core to fabricate waveguides by standard photolithography. After silanization process, efficiently and firmly bound the surface. Different concentrations NaCl solution refractive index between 1.342 1.379 detected coated nanoparticles. A set test system for established do absorbance...
This cover image shows optical amplification at 637 nm that is achieved in polymer waveguides doped with thermally activated delayed fluorescence (TADF) molecules. Under excitation of low-cost light-emitting diodes, the molecules realize process converting blue-violet light into red light, which depends on continuous absorption band material and reverse intersystem crossing process. The results, presented by Dan Zhang, Guohua Xie, co-workers article number 2200205, open new avenues for...
