1.Introduction For athletes,the quality and quantity of sleep are essential elements for optimizing recovery and subsequent performance.1 Unfortunately,athletes frequently face challenges getting sufficient,high-quality sleep.2 A recent systematic review and meta-analysis of 81 studies involving 1830 athletes concluded that compared to healthy non-athletes,athletes'sleep duration was shorter with poorer sleep efficiency.

随着我国人口的快速老龄化，严重影响老年人生活质量和身体健康的睡眠障碍愈来愈受到人们的关注。为此，本刊邀请了国际著名老年睡眠医学专家、美国华盛顿大学精神行为科学、老年医学和生物行为护理学系教授、Sleep Medicine Reviews的主编michael v.vitiello博士从老龄生理变化和疾病的影响两个方面阐述了老年睡眠障碍的发病机制，进一步提出了系统评估的原则，强调了详细采集病史的重要性，指出在此基础上开展针对性的治疗可以解决大多数老年人的睡眠障碍问题。要提高对老年睡眠障碍的诊疗水平，最重要的是要提高认识，进一步树立老龄并不意味着一定睡眠不佳的观念。

Unveiling the detection dynamics of semiconductor nanowire photodetectors by terahertz near-field nanoscopy

引用

Light(Science & Applications) 2020年第1期9卷 184-195页

作者： Eva A.A.Pogna Mahdi Asgari valentina Zannier Lucia Sorba Leonardo viti Miriam S.vitiello NEST CNR-Istituto Nanoscienze and Scuola Normale SuperiorePiazza San Silvestro 1256127 PisaItaly

Semiconductor nanowire field-effect transistors represent a promising platform for the development of roomtemperature(RT)terahertz(THz)frequency light detectors due to the strong nonlinearity of their transfer characteristics and their remarkable combination of low noise-equivalent powers(vities(>100 v/W).Nano-engineering an NW photodetector combining high sensitivity with high speed(subns)in the THz regime at RT is highly desirable for many frontier applications in quantum optics and nanophotonics,but this requires a clear understanding of the origin of the photo-response.Conventional electrical and optical measurements,however,cannot unambiguously determine the dominant detection mechanism due to inherent device asymmetry that allows different processes to be simultaneously activated.Here,we innovatively capture snapshots of the photo-response of individual InAs nanowires via high spatial resolution(35 nm)THz photocurrent nanoscopy.By coupling a THz quantum cascade laser to scattering-type scanning near-field optical microscopy(s-SNOM)and monitoring both electrical and optical readouts,we simultaneously measure transport and scattering properties.The spatially resolved electric response provides unambiguous signatures of photo-thermoelectric and bolometric currents whose interplay is discussed as a function of photon density and material doping,therefore providing a route to engineer photo-responses by design.

气-液半间歇反应器中甘油氯化:用于生产氯代醇的新型催化剂(英)

引用

催化学报 2014年第5期35卷 663-669页

作者： R.vitiello v.Russo R.Turco R.Tesser M.Di Serio E.Santacesaria Department of Chemicals Sciences University of Study of Naples "Federico Ⅱ"

Glycerol from biodiesel production can be an important industrial feedstock for chemical commodities as it can be used in the food,cosmetic,pharmaceutical and tobacco industries.However,crude glycerol derived from biodiesel production has a low value because of impurities.The purification of this glycerol into a high grade involves high costs and is not economically feasible for small and medium size plants.The glycerol conversion into chlorohydrins was studied using new homogeneous catalysts and hydrochloric acid as chlorination agent.This is an interesting alternative route to epichlorohydrin and then to epoxy resins.The behavior of two series of homologous catalysts,glycolic acid series(glycolic acid,di-glycolic acid and thio-glycolic acid) and amminoacid series(glutamic acid,aspartic acid and cysteine),were investigated for their activity and selectivity.Glycolic acids were more active than amminoacids.The pK_a values had a strong influence on selectivity(mono-chlorohydrins/di-chlorohydrins) for the amminoacid series,which was not observed for the glycolic acids.A kinetic model and reaction mechanism developed in a previous work were used for interpreting the kinetic runs.
