The proposed mechanism is a powerful methodology for estimating and detecting microscopic deformations and damage to structures.In this study, nano bubbles (NBs) of around 100 nm size were generated by using GoodSam-NB generator (made by S company) which utilizes cavitation technique. The generated NBs were directly applied to the strawberry cultivation process to monitor the productivity of strawberry. When the aqueous nutrient solution with NBs was supplied to the strawberry culture medium, it had a slightly higher initial concentration of dissolved oxygen (DO) compared to the nutrient solution prepared with ordinary groundwater at a concentration of about 9 mg/L and did not decrease over time. In other words, NBs helped to supply DO to support the development of roots in the early stage of strawberry's growth, thereby promoting the overall growth of strawberries. After feeding the NBs nutrient solution, the nitrate concentration of the discharged solution was analyzed. The concentration of the nitrate in the effluent was reduced, hence the growth of strawberry was promoted. It can be concluded that the DO contained in aqueous nutrient solution with NBs helped the nitrate to be smoothly taken from the soil.The demand for alternative energy is increasing rapidly because of global warming and the depletion of fossil fuels. Gasification is a technology that produces gaseous fuels through the incomplete combustion of waste or biomass. The introduction of a catalyst during gasification may increase the production of H₂ and reduce tar formation. In this study, the catalytic gasification of rice hulls was carried out using a fluidized gasifier. To improve the gas yield and reduce tar, municipal solid waste incineration bottom ash (IBA) having nanoporosity was introduced as a substitute for the fluidized bed material. Gasification was carried out at 800 °C, and the flow materials were silica sand, dolomite, and incineration bottom ash. The equivalence ratio, which is the ratio of oxygen supplied to oxygen required for complete combustion, was set to 0.3. The application of alternate fluidized bed materials (dolomite and incineration bottom ash) was effective in improving the hydrogen yield and tar reduction. This was attributed to the high Ca and Mg contents in dolomite and incineration bottom ash. Therefore, it is expected that IBA can be utilized as a catalytic fluidized bed material to replace silica sand.Bio-functionalized nanomaterials represent the cutting-edge research for a sensing biomolecules in nano-systems. Their physicochemical properties of porous silicon bring along advantages in sensing applications. Here, a modified biosensor based on the anti-C-reactive protein-modified porous silicon Bragg stack interferometer was developed to detect C-reactive protein. The SEM images of the surface and cross-sectional views of the Bragg stack porous silicon exhibited the pore sizes in the 10-20 nm range. The fabrication, optical characterization, and surface derivatization of the interferometer were also reported. This sensor was assessed by measuring the reflection peaks in the white light reflection spectrum. As a result, molecular binding was detected as a shift in the wavelength of these reflection peaks. In addition, a dramatic decrease in the reflectivity was observed in the reflectivity spectrum within 10 s, thereby indicating a C-reactive protein detection limit of 100 pM.In this study, plasma electrolytic oxidation (PEO) on Ti-xNb-2Ag-2Pt alloys for nano- and micro-pore formation in electrolyte with Ca and P ions for dental implant use was studied using various experimental equipment. The Ti-xNb-2Ag-2Pt alloys were fabricated using a vacuum arc melting furnace, and micro-pores were created through PEO-treatment in an electrolyte containing Ca and P ions. The PEO-treated surface was observed by X-ray diffractometer (XRD), field-emission scanning electron microscopy, and energy dispersive X-ray spectroscopy (EDS). The microstructure of Ti- xNb-2Ag-2Pt alloys showed the transformation of needle-like structure to equiaxed structure, as Nb content increased. Adding small amounts of Ag and Pt to Ti-xNb alloys, microstructure was not observed the significantly difference compared to Ti-xNb. The nano- and micro-pore sizes increased as the Nb content increased after PEO-treatment of Ti-xNb. In the case of Ti-50Nb-2Ag-2Pt, groove structure was observed, also the Ca/P ratio increased as the Nb content increased. The oxide layer thickness of Ti-xNb-2Ag-2Pt alloys was increased, as the Nb content increased.In this paper, we reported superior performance of solution-processed top-emission quantum dot light-emitting diodes (TE-QLEDs) with Mg-doped ZnO nanoparticle (NP) electron transport layer (ETL). The Mg-doped ZnO NPs were synthesized by the sol-gel method. Transmission electron microscopy (TEM) analysis of the Mg-doped ZnO NPs with 0 wt%, 5 wt%, 10 wt%, and 15 wt% Mg-doping concentrations revealed average diameters of 5.86 nm, 5.33 nm, 4.52 nm, and 4.37 nm, respectively. The maximum luminance, the current efficiency, and external quantum efficiency (EQE) were 178,561.8 cd/m², 56.0 cd/A, and 14.43%, respectively. However, for the best performance of TE-QLED without Mg-doping in the ZnO NPs, the maximum luminance was only 101,523.4 cd/m², the luminous efficiency was 27.8 cd/A, and the EQE was 6.91%. learn more The improvement of the performance is attributed to the suppression of electron transfer by an increase in the energy barrier between the cathode and Mg-doped ZnO NP ETL and the reduction in the Hall mobility of electron with increasing the Mg-doping in the ZnO NPs, resulting in the enhanced charge balance in the quantum dot (QD) emitting layer (EML).The purpose of this study was to improve the ionic conductivity and physical properties of a polymer electrolyte by complexing it with ceramic particles. First, a polymer/ceramic composite solid electrolyte was prepared by synthesizing a super porous silica aerogel powder and adding it to a slurry containing a polyethylene oxide (PEO)-based polymer electrolyte; then, the electrochemical properties of electrolyte of different compositions were confirmed. PEO and polymethyl methacrylate (PMMA) were copolymerized, the optimum ratio of lithium salt, plasticizer, and silica aerogel was determined, and ion conductivity of the composite electrolyte was improved. When the EOLi ratio was 101, the glass transition temperature was the lowest, and the room-temperature ion conductivity was improved to 3.0 × 10-5 S/cm. As a result of XRD and thermal analysis, it was confirmed that the stability and durability of the electrolyte interface can also be improved by complexation of the polymer electrolyte with ceramic particles.
