1冷藏运输用新型低温相变材料及装备的研制显示文摘本文将相变蓄冷技术应用于冷藏运输装备,以减少冷藏运输能耗及成本。利用凝固点降低原理,以丙三醇和氯化钠为原料,研制无毒低温相变材料。利用DSC测得其相变温度为-31.5℃,相变潜热为175.3 J/g。结果表明:该相变材料的密度为1.15 g/mL,导热系数为0.368 2 W/(m·K),经多次相变后化学性质稳定,属于基本无腐蚀范畴,可作为相变材料长期使用。在此基础上将其应用于蓄冷冷藏车,运行效果稳定。与机械冷藏车的经济性对比表明,虽然蓄冷冷藏车初投资较高,但制冷成本远低于机械冷藏车,静态回收期为0.57年且在废气排放、环保、节能及稳定性等方面优势明显。李靖 谢如鹤 刘广海 Alan Foster 2018制冷学报2018,39,4:23
2GU-PCM2型控温式相变蓄冷冷藏车设计与空载性能试验显示文摘现有蓄冷冷藏车蓄冷装置多位于车厢顶部,存在重心偏高、不可控温等问题,基于此,该文设计了一款集相变蓄冷单元、车载制冷系统、隔热车厢、送风系统等于一体的GU-PCM2型蓄冷冷藏车。该蓄冷车将蓄冷装置独立设置于车厢前端并保温,系统利用夜间低谷电进行充冷,可在-25~10℃之间根据需要调控车厢温度。对蓄冷冷藏车厢设定温度为0和-18℃的2种工况进行空载温度场仿真与测试。结果表明,车厢内各测温点的模拟温度与实测温度均方根误差分别为0.7和0.8℃,最大绝对误差分别为1.1和1.2℃。冷藏车可有效控温10 h以上,车厢平均温度分别在1.1~2.9℃和-14.8~-16.9℃之间,波动范围为1.8和2.1℃,温度不均匀度系数在1.0以内。控温式蓄冷冷藏车与传统蓄冷车的对比试验结果表明,其平均温度波动值降低48.7%,温度绝对不均匀度系数降低50%以上,车厢质心较顶置式蓄冷车下降25.9%。研究结果可为蓄冷冷藏车的进一步优化设计与应用提供参考。刘广海 吴俊章 Alan Foster 谢如鹤 唐海洋 邹毅峰 屈睿瑰 2019农业工程学报2019,35,6:7
3冷藏运输工具渗风特性试验与关键参数分析显示文摘针对目前国家标准中不同冷藏运输工具渗风量检测指标不统一的问题,运用静态压差法和示踪气体浓度衰减法对不同气密性条件的冷藏车展开试验,分析不同速度、不同压差、不同老化程度条件下渗风量变化规律,寻求之间的匹配关系,为相关标准的制定提供依据。研究给出了静压条件下冷藏运输工具渗风特性曲线的试验确定法和经验公式确定法,认为渗风量受工具本身气密性和速度的双重影响,且工具老化对渗风影响较大。分析表明现行铁路冷藏车、公路冷藏车和冷藏集装箱在标准测定条件下,渗风要求最大存在20倍的差距;50、100、250 Pa的测试压差分别对应30~40 km/h、45~60 km/h、70~100 km/h的运行速度,渗风量约为1∶2∶4的关系;在老化率方面,250 Pa压差条件下车辆行驶10万km和20万km后,车厢渗风量分别上升40%和110%。结合实际情况,建议将250 Pa静压差作为冷藏运输工具渗风量检测的统一测试基准值,并建立热工性能定期校验制度。刘广海 谢如鹤 Alan Foster 屈睿瑰 李锦 2016农业机械学报2016,47,10:2

8Direct detection and measurement of wall shear stress using a filamentous bio-nanoparticle显示文摘墙砍动人的液体在表面上施加的应力(WSS ) 关于脉管的功能包括那些影响许多过程。WSS 在正常生理学起一个重要作用(例如 angiogenesis ) 并且影响微脉管系统分子的运输的主要功能。波动的 WSS 的点在很多疾病显示出畸形;然而,为在生理的系统直接测量 WSS 没有确定的技术。所有当前的方法依靠大批从测量速度坡度获得的估计流动数据。在这个工作,我们报导能直接与亚微米在 microfluidic 房间测量 WSS 的 nanosensor 由使用病毒的一种特定的类型的空间分辨率,抗菌素 M13,它荧光灯地被标记并且抛锚到表面。nanosensor 能为生物织物被校准并且适应,这被表明,揭示 WSS 在不能从体积流动大小精确地计算的房间微域。这个方法在生物学和 microfluidics 把自己借给对许多应用程序适用的一个平台。Daniela P.

13Analysis of per-and polyfluoroalkyl substances in Houston Ship Channel and Galveston Bay following a large-scale industrial fire using ion-mobility-spectrometry-mass spectrometry显示文摘Per-and polyfluoroalkyl substances(PFAS)are persistent organic pollutants of concern be-cause of their ubiquitous presence in surface and ground water;analytical methods that can be used for rapid comprehensive exposure assessment and fingerprinting of PFAS are needed.Following the fires at the Intercontinental Terminals Company(ITC)in Deer Park,TX in 2019,large quantities of PFAS-containing firefighting foams were deployed.The release of these substances into the Houston Ship Channel/Galveston Bay(HSC/GB)prompted con-cerns over the extent and level of PFAS contamination.A targeted liquid chromatography-tandem mass spectrometry(LC-MS/MS)-based study of temporal and spatial patterns of PFAS associated with this incident revealed presence of 7 species;their levels gradually de-creased over a 6-month period.Because the targeted LC-MS/MS analysis was focused on about 30 PFAS molecules,it may have missed other PFAS compounds present in firefighting foams.Therefore,we utilized untargeted LC-ion mobility spectrometry-mass spectrome-try(LC-IMS-MS)-based analytical approach for a more comprehensive characterization of PFAS in these water samples.We analyzed 31 samples from 9 sites in the HSC/GB that were collected over 5 months after the incident.Our data showed that additional 19 PFAS were detected in surface water of HSC/GB,most of them decreased gradually after the incident.PFAS features detected by LC-MS/MS correlated well in abundance with LC-IMS-MS data;however,LC-IMS-MS identified a number of additional PFAS,many known to be compo-nents of firefighting foams.These findings therefore illustrate that untargeted LC-IMS-MS improved our understanding of PFAS presence in complex environmental samples.Alan Valdiviezo Noor AAly Yu-Syuan Luo Alexandra Cordova Gaston Casillas MaKayla Foster Erin SBaker Ivan Rusyn 2022Journal of Environmental Sciences2022,34,5:0
14温哥华公寓显示文摘温哥华公寓的建成预示着这个年轻的城市正在打开城市政策制定的新局面。它将成为从Granville大桥进入温哥华市中心的城市大门。塔楼和群房的设计是对新城市主义地域类型中的'温哥华主义'建筑的全新解读,配合一座纤细的塔楼,试图保留城市视觉通廊并激活步行通道。住宅塔楼借助高度和毗邻河流的地理位置,是唯一可以同时享受水景和山景的建筑,坐拥温哥华广袤的自然风光。Carl McDonald Melissa Bauld Aaron Mark Alan Tansey Alex Wu Alexandra Gustafsson Alina Tamosiunaite Amina Blacksher Aran Coakley Arash Adel Ahmadian Armen Menendian Barbora Srpkova Ben Zunkeler Benjamin Caldwell Benjamin Novacinski Bennett Gale Birk Daugaard Blake Theodore Smith Brian Foster Brian Rome Carolien Schippers Christopher James Malcolm Jr. Christopher Junkin Christopher Tron David Brown David Dottelonde Deborah Campbell Doug Stechschulte Douglass Alligood Edward Yung Elena Bresciani Filip Milovanovic Francesca Portesine Gabriel Hernandez Solano Gabriel Jewell-Vitale Hector Garcia Ivy Hume Jan Leenknegt Janice Rim John Kim Josiah Poland Julian Liang Julianne Gola Julie Kaufman Karol Bogdan Borkowski Kurt Nieminen Lauren Turner Lorenz Krisai Lucio Santos Marcella Martinez Martin Voelkle Matthew Dlugosz Megan Ng Michael Robert Taylor Otilia Pupezeanu Paula Domka Phillip MacDougall Ryan Yang Sean Franklin Sebastian Grogaard Simon Scheller Spencer Hayden Taylor Fulton Terrence Chew Terry Lallak Thomas Smith Tianqi Zhang Tobias Hjortdal Tran Le Valentina Mele Xinyu Wang Yaziel Juarbe Yoanna Shivarova Zach Walters Zhifei Xu Andrew Latreille Glotman Simpson Urban YVR 运小红(译) 2019城市环境设计2019,0,2:0
