Modeling and analysis of a rotational piezoelectric energy harvester with limiters

Xiaobo Rui,Zhoumo Zeng,Yibo Li,Yu Zhang,Zi Yang,Xinjing Huang,Zhou Sha 대한기계학회 2019 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.33 No.11

A rotational piezoelectric energy harvester has the ability to convert rotation mechanical energy into electric power. The piezoelectric harvester with cantilever based on gravity excitation has received great attention. Given that gravity excitation is greater than conventional vibration excitation, and large mass are often used in low-frequency applications, large amplitudes pose a significant threat to the life of a harvester. In this study, a rotational energy harvester with limiters is investigated to promote practical development. This study establishes a theoretical model verified by experiments. Results show that stiffness has little influence on the limiting effect. In the experimental conditions, the output after 2000 N/m is basically the same. The peak value of the output voltage is linearly proportional to the space. Given that an impact excitation is generated in the collision, the limiter widens the frequency band of the output in the upsweep.

Xu Huang,Kun Jia,Xiaobo Liu 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.7

TiO2@MWCNT heterostructure containing single one carbon nanotube has been successfully prepared via solvothermal method. X-ray diffration (XRD) analysis shows that TiO2 nanocrystals only contain highly crystallized tetragonal anatase phase. Interestingly, scanning electron microscope (SEM) and transmission electron microscope (TEM) results show that most of the TiO2 nanocrystals are perpendicular to the surface of multi-walled carbon nanotube (MWCNT) and only single one carbon nanotube is coated by TiO2 crystals. The electromagnetic (EM) characteristics are investigated at 0.5–18.0 GHz range. The EM properties show that both the permittivity and the permeability present a typical resonance behavior at 11.0 GHz and 12.0 GHz, respectively. Besides, the TiO2@MWCNT heterostructures exhibit a broadband absorption throughout the whole Ku wave bands (12.0–18.0 GHz) Interestingly, the reflection loss (RL) of the TiO2@MWCNT heterostructures change slightly as the thickness of the heterostructures increase from 3.0 mm to 5.0 mm in the 8.0–13.0 GHz range.

Wen-wu Huang,Xiaobo Li,Meng Yue Wang,Hai-ming Shi,Ying Peng,Chong-sheng Peng,Min Zhang,Yue Li,Jing Lu 대한약학회 2012 Archives of Pharmacal Research Vol.35 No.11

Two HPLC methods with diode array detection (HPLC-DAD) and electrospray ionization-mass spectrometry (HPLC-ESI/MS), respectively, were developed to investigate the differences of chemical constituents and their metabolism in gastrointestinal tract in vitro between two decoctions of crude and processed Glycyrrhizae radix. Total of eleven constituents (liquiritin apioside, liquiritin, licuraside, isoliquiritin, ononin, glycyrrhizin, liquiritigenin-7,4'-diglucoside, licorice saponin A3, 22β-acetoxylglycyrrhizic acid, licorice saponin G2, and yunganoside E2) were identified in the two decoctions, whereas lower contents of these constituents were usually found in the decoction of processed G. radix. Furthermore, these constituents were metabolized into their respective aglycons in human intestinal bacteria juice, and the metabolism ratios were all higher in processed G. radix decoction. No change was found in artificial gastric or intestinal juice. This study revealed that the processing can alter the contents of main constituents in crude G. radix and their metabolism in gastrointestinal tract, in which intestinal bacteria play an important role in the metabolism of licorice constituents.

Meng Yaping,Yu Xinyue,Huang Qiang,Zhang Li Zhen,Wu Xiaobo,Wang Zilong,Yan Wei Yu 한국응용곤충학회 2022 Journal of Asia-Pacific Entomology Vol.25 No.1

The high prevalence of honeybee viral diseases poses a severe threat to the health of honeybees and causes substantial economic losses worldwide. Sacbrood virus (SBV) is a single-strand RNA virus that infects honeybees at all life stages. The infection can shorten the lifespan of adult bees and is lethal to larvae. SBV is the major cause of honeybee losses in Asia. Genetic and phylogenetic analyses of SBV isolates from different areas have been previously conducted. However, the impact of Apis mellifera Linnaeus and Apis cerana Fabricius coexistence on the infection and phylogeny of SBV remains unknown. In this study, we collected A. cerana and A. mellifera samples from commercial apiaries, only A. cerana in mountainous region. SBV prevalence was evaluated in three commercial apiaries of Jinxi, Tonggu and Nanchang and two mountainous regions of Zixi and Yifeng. In our sampling location, we found a higher SBV prevalence in the mountainous regions than in commercial apiaries. Partial structural polyprotein coding sequences were sequenced and compared with other GenBank SBV isolates. Phylogenetic tree topologies showed that SBV isolates form two major groups based on their host specificity, and isolates from same country tend to cluster together in subclades, indicating that the host and geographic region has significant effects on SBV strain specificity.

Haroon Elrasheid Tahir,Li Zhihua,Gustav Komla Mahunu,Zou Xiaobo,Muhammad Arslan,Huang Xiaowei,Zhikun Yang,Abdalbasit Adam Mariod 한국식품과학회 2020 Food Science and Biotechnology Vol.29 No.2

The marketability of blueberries over long distances has been limited because of their highly perishability. To prolong the postharvest shelf life and conserve quality properties of blueberry, various alternatives have been evaluated. We studied the influence of gum arabic (GA) alone or GA enhanced with African baobab (AB) fruit extract on blueberry during cold storage (4 C) for 21 days. Physico-chemical properties (e.g. pH, color, firmness, and weight loss), microbial decay, antioxidant properties, polyphenol oxidase (PPO) and peroxidase (POD) activity were investigated. The fruit treated with GA combined AB indicated a significant delay in microbial decay, firmness loss, weight loss, and color change. The treatments on blueberries resulted in better preservation of total phenols and total anthocyanins delayed the increase in total soluble solids as compared to the control. The coatings lowered the activities of PPO and POD enzymes and delayed microbial decay in coated blueberry during 21 days of storage.

Jing Liu,Yanhang Gao,Xianbo Wang,Zhiping Qian,Jinjun Chen,Yan Huang,Zhongji Meng,Xiaobo Lu,Guohong Deng,Feng Liu,Zhiguo Zhang,Hai Li,Xin Zheng 연세대학교의과대학 2020 Yonsei medical journal Vol.61 No.2

Purpose: This study investigated multidrug-resistant (MDR) pathogens and antibiotic strategies of culture-positive spontaneousascitic infection (SAI) in patients with acute decompensated cirrhosis. Materials and Methods: We retrospectively analyzed 432 acute decompensated cirrhotic patients with culture-positive SAI from11 teaching hospitals in China (January 2012 to May 2018). A Cox proportional hazards model analysis was conducted to identifyindependent predictors of 28-day mortality. Results: A total of 455 strains were isolated from 432 ascitic culture samples. Gram-negative bacteria (GNB), gram-positive bacteria(GPB), and fungi caused 52.3, 45.5, and 2.2% of all SAI episodes, respectively. Episodes were classified as nosocomial (41.2%), healthcare-related (34.7%), and community-acquired (24.1%). Escherichia coli (13.4%) and Klebsiella pneumoniae (2.4%) were extendedspectrumβ-lactamase producing isolates. The prevalence of methicillin-resistant Staphylococcus aureus was 1.1%. Ceftazidime,cefepime, aztreonam, and amikacin were recommended as first-line antibiotics agents for non-MDR GNB infections; piperacillin/tazobactam and carbapenems for MDR GNB in community-acquired and healthcare-related or nosocomial infections, respectively;and vancomycin or linezolid for GPB infections, regardless of drug-resistance status. Multivariate analysis revealed days ofhospital stay before SAI, upper gastrointestinal bleeding, white blood cell count, alanine aminotransferase, serum creatinine concentration,total bilirubin, and international normalized ratio as key independent predictors of 28-day mortality. Conclusion: MDR pathogens and antibiotic strategies were identified in patients with acute decompensated cirrhosis with culture-positive SAI, which may help optimize therapy and improve clinical outcomes.
