Waste-to-Resource Strategy To Fabricate Highly Porous Whisker-Structured Mullite Ceramic Membrane for Simulated Oil-in-Water Emulsion Wastewater Treatment

Industrial waste coal fly ash, containing hazardous metal oxides, poses potential threats to the environment and humans. Efficient recycling of such kind of solid state waste is highly desired yet still challenging. This work addressed waste-to-resource fabrication of a highly porous whisker-structured mullite ceramic membrane for separation of simulated oil-in-water emulsion wastewater by recycling of waste fly ash and natural bauxite with addition of WO₃. The formation and characterizations of membranes were systematically studied including reaction mechanism, dynamic sintering behavior, open porosity, mechanical property, pore size distribution, microstructure, and pure water flux. The results show mullite formation temperature was decreased about 100 °C with addition of 20 wt % WO₃, whereas open porosity significantly increased with WO₃ content due to the formation of a highly porous interlocked whisker structure. Even without any pore formers, interestingly, the membrane with addition of 20 wt % WO₃ possessed an open porosity as high as 51.9 ± 0.3% after sintering at a high temperature of 1400 °C whereas its mechanical strength (68.7 ± 6.1 MPa) was still improved. An oil-in-water emulsion dead-end microfiltration experiment indicates a significantly improved oil rejection as high as 99% was also obtained for W20 membrane, as compared to that (83%) of the W0 membrane

Energy Upconversion in Lanthanide-Doped Core/Porous-Shell Nanoparticles

Here, we report upconversion nanoparticles with a core/porous-shell structure in which bulk emission and nanoemission are simultaneously observed. The activated porous shell can efficiently tune the bulk emission but has negligible influence on the nanoemission

An Improved Wavelet Packet-Chaos Model for Life Prediction of Space Relays Based on Volterra Series

<div><p>In this paper, an improved algorithm of wavelet packet-chaos model for life prediction of space relays based on volterra series is proposed. In the proposed method, the high and low frequency time sequence components of performance parameters are obtained by employing the improved wavelet packet transform to decompose the performance parameters of the relay into multiple scales. Then the optimization algorithm of parameters in volterra series is improved, and is used to construct a chaotic forecasting model for the high and low frequency time sequence components gained by the wavelet packet transform. At last, the chaotic forecasting results of the high and low frequency components are combined by taking the wavelet packet reconstruction approach, so as to predict the lifetime of the studied space relay. The algorithm can predict the life curve of the relay accurately and reflect the characteristics of the relay performance with sufficient accuracy. The proposed method is validated via a case study of a space relay.</p></div

Conjugated Oligomer-Based Fluorescent Nanoparticles as Functional Nanocarriers for Nucleic Acids Delivery

Oligonucleotides such as siRNA and plasmid DNA (pDNA) have great potential for gene therapies. Multifunctional, environment-resistant carriers with imaging capabilities are required to track the assembly and disassembly of oligonucleotides, monitor the delivery processes, and develop new delivery systems. Conjugated polymers and oligomers can potentially be used as novel materials for functional nanocarriers with both delivery and imaging abilities. In this work, a novel π-conjugated oligomer 4,7-(9,9′-bis­(6-adenine hexyl)­fluorenyl)-2,1,3-benzothiadiazole (OFBT-A) modified with nucleotide adenine (A) groups in its side chains is synthesized and characterized. Fluorescent nanoparticles based on the π-conjugated oligomers OFBT-A are developed as novel functional nanocarriers for oligonucleotides. Single-stranded DNA (ssDNA) TR-T5 labeled with Texas Red (TR) fluorescent dye is selected as a model payload oligonucleotide. The capture abilities and stability of OFBT-A are investigated by monitoring the fluorescence resonance energy transfer (FRET) efficiency between the OFBT-A nanoparticles and TR labels in solution. The OFBT-A/TR-T5 composites are stable in solution at high ionic strengths (0–500 mM) and have a wide working pH range, from 3.0 to 9.5. The in vitro profile demonstrates that the release of the TR-DNA is induced by the ssDNA A43, which has a high charge density. The release process is monitored by measuring the changes in FRET efficiency and fluorescence color for the OFBT-A/TR-T5 composites. Using this carrier, the uptake of TR-DNA by A549 lung cancer cells is observed. Both the OFBT-A nanoparticles and the OFBT-A/TR-T5 composites show high cytocompatibility. We anticipate that these novel functional nanocarriers will provide a safe strategy for monitoring the gene delivery process
