Study on Electrocatalytic Oxidation of sec-Butyl Alcohol on Pt Electrode Modified with Adatoms
运用电化学循环伏安和石英晶体微天平研究了HClO4溶液中仲丁醇在Pt电极及以Sb和S吸附原子修饰的Pt(Pt/Sbad和Pt/Sad)电极上的电催化氧化过程 .从电极表面质量变化可以看出 ,仲丁醇的氧化与电极表面的氧物种有着极其密切的关系 .Pt电极表面Sb吸附原子可在较低的电位下吸附氧 ,明显提高仲丁醇的氧化活性 .与Pt电极相比 ,Sb吸附原子修饰的Pt电极使仲丁醇氧化的峰电位负移约 10 0mV .相反 ,Pt电极表面S吸附原子的氧化会消耗表面氧物种 ,抑制仲丁醇的氧化 .从电极表面质量变化提供了吸附原子电催化作用的数据The processes of adsorption and oxidation of sec butyl alcohol on Pt electrode and Pt electrodes modified with Sb and S (Pt/Sb ad and Pt/S ad ) were studied by using cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM). The results demonstrated that the oxidation of sec butyl alcohol depends strongly on oxidation states of electrode surface. Sb adatoms on Pt surface can adsorb oxygen at relatively low potentials, and exhibit catalytic effects for sec butyl alcohol oxidation. In comparison with the case of Pt electrode, the oxidation peak potential of sec butyl alcohol on Pt surface modified with Sb was negatively shifted about 100 mV. On the contrary, the oxidation of S adatoms consumes oxygen species on Pt electrode surface. As a consequence, the oxidation of sec butyl alcohol was inhibited by the presence of S ad . The EQCM studies provided quantitative results of surface mass changes during sec butyl alcohol oxidation, and have thrown new light on elucidating different effects of adatoms Sb ad and S ad on Pt electrode towards sec butyl alcohol oxidation.国家自然科学基金 (2 983 3 0 60 );; 教育部博士点专项科研基金 (19990 3 840 3 );; 福建省教委科研基金资助项目 (K2 0 0 110 1

Study on electrocatalytic oxidation of sec-butyl alcohol on pt electrode modified with adatoms
The processes of adsorption and oxidation of sec-butyl alcohol on Pt electrode and Pt electrodes modified with Sb and S (Pt/Sb-ad and Pt/S-ad) were studied by using cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM).

佐久地域の事業所における健康管理等に関する実態調査について
要旨:佐久地域の事業所における労働者の定期健康診断及び保健指導、被扶養者の特定健診、受動喫煙防止対策、労働者の昼食のそれぞれの状況について調査した。その結果、定期健康診断実施後のフォローアップや保健指導の実施に課題がみられた。被扶養者は、特定健診を受診しやすい環境にあるとは言えない状況がうかがえ、受動喫煙防止対策については一層の推進が必要であった。また、労働者は昼食として市販の弁当を利用している状況が明らかとなった。事業所における健康づくりが向上するよう、今後、佐久地域保健・職域保健連携推進協議会で対策を検討し、活動につなげていきたい。Article信州公衆衛生雑誌 10(1): 22-23(2015)journal articl
「“さく”っとうす味みんなでキャンペーン」の取組について
要旨:減塩をより一層推進するため、地域の関係機関・団体と連携して減塩キャンペーンを実施した。関係機関・団体の積極的な活動により目標を上回る実施ができた。今回の取組の中で働き盛り世代への取組の必要性が明らかとなったが十分なアプローチができていなかったため、今後は働き盛り世代を意識しながら、引き続き関係者一丸となった取組を進めていく。Article信州公衆衛生雑誌 11(1): 44-45(2016)journal articl

Zhangzhou Inst Technol, Dept Food & Bioengn, Zhangzhou, Fujian Peoples R ChinaA linear trinuclear Co(II) compound, [Co-3(mu(1,1)-N-3)(4)(N-3)(2)(H2O)(2)(bpbp)(2)] center dot 2H(2)O (1, bpbp = 3,3'-bis-Dimethytamino-1,1'-pyridine-2,6-diyl-bispropenone), is reported. The central Co(II) ion is bridged to Co(II) ions on both sides by four end-on azide (mu(1,1)-N-3(-)) ligands resulting in a centrosymmetric trimer with adjacent Co center dot center dot center dot Co distance of 3.233 angstrom. Each Co(II) ion possesses distorted octahedral geometry, the central one is coordinated by two aqua ligands and four mu(1,1)-N-3(-) nitrogen atoms and each terminal Co(II) is coordinated by two mu(1,1)-N-3(-) nitrogen atoms, one terminal N-3(-) nitrogen atom and capped by terminal tridentate bpbp ligand. Variable temperature magnetic studies indicate ferromagnetic coupling between adjacent Co(II) ions within the trimer. Crown Copyright (C) 2008 Published by Elsevier B.V. All rights reserved
