Immobilization of cross-linked In-doped Mo(O,S)2 on cellulose nanofiber for effective organic-compound degradation under visible light illumination

Progress in Natural Science:Materials International 2021年第3期31卷 404-413页

Ltd. Graduate School of Technology Industrial and Social Sciences Tokushima University

Relatively small amounts of In-doped Mo(O,S)2(IMS) catalysts(10%, 20%, and 30%) were deposited on cellulose nanofiber(CNF) by cross-linking them with functional groups of siloxane and epoxy to form CNF-IMS hybrid composites. The as-prepared hybrid composites were characterized and tested their performances toward the photo degradations of cationic(MB and Rh B) and anionic(MO) dyes. As indium was doped into Mo(O,S)2lattice to form solid-solution, the charge transfer and photocarrier separation during the catalytic reaction were simultaneously enhanced as probed with electrochemical impedance spectroscopy and photoluminescence measurements, respectively. To ensure the catalyst on CNF was well deposited and recyclable, the hybrid composite was evaluated with a reusability experiment to show the stability performance in degrading organic dyes. It was found the environmentally friendly CNF-IMS hybrid composite was relatively stable during the reusability experiment, indicating no catalyst powder was leached out during the photocatalytic reaction. The photoreaction mechanism was convinced by radical-scavenging experiments to show that hydroxyl and superoxide played essential roles for the organic dye degradations in visible-light illuminated conditions. The cross-linked organic/inorganic hybrid catalyst showed a prospective visible light active material not only to solve the environmental issue due to the leaching of nanoparticles but also to lower the post-treatment/recycling cost of photocatalyst in industrial application.

Boyd的工作不仅由于对福氏痢疾杆菌型抗原和群抗原的发现而奠定了本菌血清学分类的基础,同时也最早地叙述了福氏痢疾杆菌型抗原消失变异现象。这一现象其后由Weil,Veazie及Ewing等相继证实。此后,Ewing发现了福氏痢疾杆菌的另一种抗原变异现象,称为群抗原的形体变异。日本学者同部建藏将福氏痢疾杆菌1—4型用血清诱导的方法,成功地重复了型抗原消失变异,分别获得了Y变种,又由这些Y变种进一步用群3,4因子血清诱导,获得了不合群3,4抗原的菌株,并将此种菌株称为'C相'菌。我们曾在菌型鉴定工作中获得不与各型及群因子血清凝集而仅在福氏多价血清中凝集的福氏痢疾杆菌2株。此类菌株是否由抗原变异所产生则尚不明了。

Exploratory use of ultrasound to determine whether demyelination following carpal tunnel syndrome co-exists with axonal degeneration

引用

Neural Regeneration Research 2018年第2期13卷 317-323页

Carpal tunnel syndrome （CTS） accompanied by secondary axonal degeneration cannot be clearly dis- criminated using the current cross-validated ultrasound severity classification system. This study aimed at exploring cut-off values of ultrasound parameters, including wrist cross-sectional area （W-CSA）, wrist perimeter （W-P）, ratio of cross-sectional area （R-CSA） and perimeter （R-P）, changes of CSA and P from wrist to one third distal forearm （△CSA＆AP） for differentiation. Seventy-three patients （13 male and 60 female） were assigned into group A （demyelination only, n = 40） and group B （demyelination with secondary axonal degeneration, n = 33） based on the outcomes of nerve conduction studies （NCS）. Receiver Operative Characteristics （ROC） curves were plotted to obtain sensitivity, specificity, and accuracy of cut- off values for all the ultrasound parameters. The overall identified cut-off values （W-CSA 12.0 mm2, W-P 16.27 mm, R-CSA 1.85, R-P 1.48, △CSA 6.98 mm2, △P 5.77 mm） had good sensitivity （77.1-88.6%）, fair specificity （40-62.2%） and fair-to-good accuracy （0.676-0.758）. There were also significant differences in demographics （age and severity gradation, P 〈 0.001）, NCS findings （wrist motor latency and conduction velocity, P 〈 0.0001; wrist motor amplitude, P 〈 0.05; distal sensory latency, P 〈 0.05; sensory amplitude, P 〈 0.001） and ultrasound measurements （W-CSA, W-P, R-CSA, R-P, △CSA＆△P, P 〈 0.05） between groups. These findings suggest that ultrasound can be potentially used to differentiate demyelinating CTS with sec- ondary axonal degeneration and provide better treatment guidance.

There are increasing concerns about internet gaming disorder (IGD). No review of existing studies has systematicallyanalyzed and visualized the trends of IGD and those early identification of symptoms related to IGD *** critical review focuses on the emerging trends for early identification of symptoms related to IGDbehaviors in papers published in Web of Science Core Collection from 2009 to 2021 by scientometric analysisand critical review. Scientometric data analysis technique includes co-occurrence analysis, cluster analysis andburst analysis of authors, countries, keywords and co-citation to visualize those contributing and associated factorsto develop IGD behaviors and their relationships to mental-emotional symptoms. About 81.8% of the paperswere published in the following countries: United States, United Kingdom, Australia, China and South Korea. Thetop co-occurrence keywords were ‘children’, ‘depression’, ‘anxiety’ and ‘attention deficit hyperactivity disorder(ADHD)’, ‘scale’, identifying the population, characteristics and commonly used assessment tools that are susceptibleto certain symptoms relating to IGD of which influencing factors facilitate the understanding of the associationof sociodemographic characteristics. The main emerging topics were identified in this critical review afterconducted the scientometric analysis. The results identified five topics: game impulse, motivation, evaluationscale, mediating effects and diagnostic criteria. This study provides an overview of the research trends on theidentity and development of the IGD field of study.
