Yingjie Fu,Dongjie Li,Jian Song,Yujia Sheng 보안공학연구지원센터 2014 International Journal of Control and Automation Vol.7 No.10

With the development of modern technology, the intelligent household appliances are more and more popular among people. However, now the lamps on the market are mostly ordinary lamps, and they can not meet the requirements of users. Because of that situation, in this paper, an intelligent lamp based on virtual reality and face/book and voice recognition is designed. Firstly, the master control circuit and peripheral functional circuit of the intelligent lamp are designed with the key of ATMEGA2560 micro dips, and the body of the lamp is designed. At the same time, the virtual environment carrying virtual three-dimensional model is developed using Java (based on cell phone) and C++ (based on personal computer). The Open CV algorithms are used to identify images of objects that the intelligent lamp uploads. Users can interact with intelligent lamp between peripheral functional circuit and virtual environment. There are many characteristics of this intelligent lamp, such as, variety of control mode, high intelligent, stable performance, simple operation, high degree of user experience and so on. Users can modify the PC code and add related module at the reserved ports of the lamp to achieve more functions.

Simultaneous NO/SO2 removal by coconut shell char/CaO from calcium looping in a fluidized bed reactor

Boyu Li,Yingjie Li,Wan Zhang,Yuqi Qian,Zeyan Wang 한국화학공학회 2020 Korean Journal of Chemical Engineering Vol.37 No.4

A simultaneous NOx/SO2 removal system using bio-char and CaO combined with calcium looping process for CO2 capture was proposed. The simultaneous NO/SO2 removal performance of coconut shell char/CaO experienced CO2 capture cycles was investigated in a fluidized bed reactor. The effects of reaction temperature, mass ratio of CaO to coconut shell coke, CaO particle size and number of CO2 capture cycles from calcium looping process were discussed. The NO removal efficiency of char is improved under the catalysis of CaO. The reaction temperature plays an important role in the simultaneous NO/SO2 removal. Coconut shell char/CaO achieve the highest NO and SO2 removal efficiencies at 825 oC, which are 98% and 100%, respectively. The mass ratio of CaO to coconut shell char of 60 : 100 is a good choice for the simultaneous NO/SO2 removal. Smaller CaO particle size contributes to higher NO and SO2 removal efficiencies of coconut shell char/CaO. The NO and SO2 removal efficiencies of coconut shell char and cycled CaO from calcium looping declined slightly with the number of CO2 capture cycles. In addition, the Ca-based materials balance in process of simultaneous NOx/SO2 removal combined with calcium looping is given. The novel simultaneous NO/SO2 removal method using bio-char and cycled CaO from calcium looping process appears promising.

Twin-screw extrusion synthesis of low-cost cobalt ferrite ceramic pigments using natural mixed-dimensional palygorskite clay

Yingjie Zhu,Shue Li,Bin Mu,Hao Yang,Lei Wu,Qin Wang,Aiqin Wang 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.122 No.-

Due to the disadvantages of traditional solid-phase and liquid-phase methods for preparation of mixedmetal oxide ceramic pigments, it is indispensable to develop a green, clean, low-cost and continuouspreparation technology. In this study, the low-cost and high-performance cobalt ferrite ceramic pigmentswere facilely prepared based on natural mixed-dimensional palygorskite clay by a continuousmechanochemical method using twin-screw extrusion. The incorporation of the mixed-dimensionalpalygorskite clay effectively improved the agglomeration of pigment nanoparticles and decreased theproduction cost. The hybrid pigments presented the optimal color properties (L* = 17.16, a* = 1.07, b* =3.58 and C* = 3.74) when the cobalt ferrite content, calcination temperature and time were 60 wt%,1100 C and 90 min, respectively. Furthermore, the as-prepared hybrid pigments exhibited excellentchemical and thermal stability and biocompatibility, the mass tone and hiding power of the hybrid pigmentswere superior to the commercial cobalt black pigments, thus the obtained hybrid pigments couldbe served as an eco-friendly underglaze pigment for coloring of ceramic embryo body with good colorsaturation. Beyond all doubt, this study will provide a promising strategy for continuous cleaner preparationof low-cost cobalt ferrite ceramic pigments.

BACKGROUND: Intervertebral disk (IVD) degeneration, which can cause lower back pain, is a major predisposing factor for disability and can be managed through multiple approaches. However, there is no satisfactory strategy currently available to reconstruct and recover the natural properties of IVDs after degeneration. As tissue engineering develops, scaffolds with embedded cell cultures have proved critical for the successful regeneration of IVDs. METHODS: In this study, an integrated scaffold for IVD replacement was developed. Through scanning electron microscopy and other mechanical measurements, we characterized the physical properties of different hydrogels. In addition, we simulated the physiological structure of natural IVDs. Nucleus pulposus (NP) cells and annulus fibrosusderived stem cells (AFSCs) were seeded in gelatin methacrylate (GelMA) hydrogel at different concentrations to evaluate cell viability and matrix expression. RESULTS: It was found that different concentrations of GelMA hydrogel can provide a suitable environment for cell survival. However, hydrogels with different mechanical properties influence cell adhesion and extracellular matrix component type I collagen, type II collagen, and aggrecan expression. CONCLUSION: This tissue-engineered IVD implant had a similar structure and function as the native IVD, with the inner area mimicking the NP tissue and the outer area mimicking the stratified annulus fibrosus tissue. The new integrated scaffold demonstrated a good simulation of disc structure. The preparation of efficient and regeneration-promoting tissueengineered scaffolds is an important issue that needs to be explored in the future. It is hoped that this work will provide new ideas and methods for the further construction of functional tissue replacement discs.

Objective: The objectives of this study were to evaluate the effects of daily feed intake during the laying period on embryonic myogenic differentiation 1 (MYOD1), myogenic factor 5 (MYF5), and myogenic factor 6 (MYF6) gene expression in genetically fat and lean lines of chickens. Methods: An experiment in a 2×2 factorial design was conducted with two dietary intake levels (100% and 75% of nutrition recommendation) and two broiler chicken lines (fat and lean). Two lines of hens (n = 384 for each line) at 23th week of age were randomly divided into 4 treatments with 12 replicates of 16 birds. The experiment started at 27th week of age (5% egg rate) and ended at 54th week of age. Hatched eggs from the medium laying period were collected. Real time polymerase chain reaction analysis was used to analyse the MYOD1, MYF5, and MYF6 mRNA levels of E7, E9, E11, E13, and E15 body tissues and E17, E19, and E21 chest and thigh muscle samples. Results: The results indicated that there were significant effects of line, dietary intake, and interactions between them on MYOD1, MYF5, and MYF6 gene mRNA expression levels in embryonic tissues. Low daily feed intake did not change the expression trend of MYOD1 mRNA in either line, but changed the peak values, especially in lean line. Low daily feed intake altered the trend in MYF5 mRNA expression level in both lines and apparently delayed its onset. There was no apparent effect of low daily feed intake on the trends of MYF6 mRNA expression levels in either line, but it significantly changed the values on many embryonic days. Conclusion: Maternal nutrient restriction affects myogenesis and is manifested in the expression of embryonic MYOD1, MYF5, and MYF6 genes. Long term selection for fat deposition in broiler chickens changes the pattern and intensity of myogenesis.
