Abstract Microscale cell carriers have recently garnered enormous interest in repairing tissue defects by avoiding substantial open surgeries using implants for regeneration. In this study, the highly porous microspheres (HOPMs) are fabricated a microfluidic technique harboring proliferating skeletal myoblasts and evaluating their feasibility toward delivery application situ. These biocompatible HOPMs with particle sizes of 280–370 µm possess pores 10–80 interconnected paths. Such structure...
Semiconductor quantum dots (QDs) composed of multiple components are playing an important role in solar energy conversion as light harvesting materials. Electron extraction dynamics CdSe and core/shell CdSe/CdS/ZnS colloidal QDs studied by femtosecond transient absorption spectroscopy this Article. Our study demonstrates that, the presence commonly used electron acceptor, methyl viologen (MV2+), electrons 1S state can be effectively extracted with a time constant less than 150 fs. With...
Abstract Cooperative performance of mixed‐valent Eu 2+ /Eu 3+ in single‐compound phosphors offers significant advantages color rendering and luminescence efficiency, but their synthesis is challenging because oxidation. Using the tunable nature metal‐ion nodes metal–organic frameworks (MOFs), we present an situ reduction crystallization route for preparing MOFs doping with a controlled ratio. These materials exhibit rich photoluminescence, including intrinsic‐ sensitized‐emissions ,...
Luminescent Au(I)–thiolate complexes (Au(I)–SR) are synthesized at room temperature using glutathione as both a reducing agent and capping ligand. The photoluminescence (PL) intensity emission wavelength found to be strongly affected by the pH environment during post synthesis. Although there is no Au(0) core present in these complexes, Au(I)–SR exhibit PL which can further enhanced through an aggregation-induced mechanism. structures of each stage carefully characterized. Using X-ray...
Reported here is the design and fabrication of three-dimensional (3D) "overpass" microstructures at junction crossed microfluidic channels by femtosecond laser direct writing photopolymers. The post-integrated overpass could be used for guiding different microfluids across without mixing; therefore it proposed as an enabler achieving 3D chips based on conventional two-dimensional (2D) microchannels. As representative examples, bi-crossed tri-crossed microchannels have been equipped with...
Artificial dressings composed of degradable polymer materials have a wide range applications in skin repair.
We experimentally demonstrate fabrication of a spiral-shaped polymer microdisk cavity by femtosecond laser direct writing via two-photon polymerization dye-doped resins. This spiral microresonator supports highly directional emission from the notch with high-Q factor exceeding 1.6 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> and low lasing threshold at room temperature. Our numerical simulation results reveal that clockwise...
The unified power flow controller (UPFC) is a tool in the implementation of flexible AC transmission systems (FACTS). It provides for equivalent static VAr compensation and series injection using back-to-back force commutated converters. This paper proposes control strategy to extend UPFC operation allow isolation harmonics due nonlinear loads. Simulation results based on Electromagnetic Transients Program (EMTP) are used illustrate device performance system environment. Experimental single...

The paper presents an analysis and control method for a high speed phase shifter (HSPS) involved in interconnected power system. An HSPS is visualised as ideal connected series with its reactance. To include the dynamic characteristics of into system, terminal are represented node injections. Resulting from representation, effects HSPSs obtained additional bus injections at generator internal buses. This shows that modulation interties by can cause output effective system stabilising...
Minimally invasive implantation of porous implants with large volume for in vivo filling proposes high requirements material preparation. Porous scaffolds based on shape memory polymer (SMP) possess great potential being delivered as the compact form via minimally surgery. Here, poly (ε-caprolactone)-dienes (PCL-dienes) and crylic acid (AA) were polymerized cross-linked to fabricate SMP scaffolds, structure which was created through particle leaching method. Three PAA-PCL20, PAA-PCL50...
As a new light-emitting material, quantum dot having the advantages of other materials that can not be replaced. It is only fluorescence yield, and light stability.
