1Petawatt and exawatt class lasers worldwide显示文摘In the 2015 review paper‘Petawatt Class Lasers Worldwide’a comprehensive overview of the current status of highpower facilities of>200 TW was presented.This was largely based on facility specifications,with some description of their uses,for instance in fundamental ultra-high-intensity interactions,secondary source generation,and inertial confinement fusion(ICF).With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification(CPA),which made these lasers possible,we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed.We are now in the era of multi-petawatt facilities coming online,with 100 PW lasers being proposed and even under construction.In addition to this there is a pull towards development of industrial and multi-disciplinary applications,which demands much higher repetition rates,delivering high-average powers with higher efficiencies and the use of alternative wavelengths:mid-IR facilities.So apart from a comprehensive update of the current global status,we want to look at what technologies are to be deployed to get to these new regimes,and some of the critical issues facing their development.Colin N.Danson Constantin Haefner Jake Bromage Thomas Butcher Jean-Christophe FChanteloup Enam A.Chowdhury Almantas Galvanauskas Leonida A.Gizzi Joachim Hein David I.Hillier Nicholas W.Hopps Yoshiaki Kato Efim A.Khazanov Ryosuke Kodama Georg Korn Ruxin Li Yutong Li Jens Limpert Jingui Ma Chang Hee Nam David Neely Dimitrios Papadopoulos Rory R.Penman Liejia Qian Jorge J.Rocca andrey A.Shaykin Craig W.Siders Christopher Spindloe Sándor Szatmári Raoul M.G.M.Trines Jianqiang Zhu Ping Zhu Jonathan D.Zuegel 2019High Power Laser Science and Engineering2019,7,3:33
2An analysis of new generation coal gasification projects显示文摘The global trends of increasing oil and gas costs have compelled coal possessing countries to start long term underground coal gasification(UCG) projects.These enhance national energy security and are among the cleanest,ecologically safest coal utilization technologies.This paper delineates the major characteristics of such technologies and analyzes technical solutions.Highlighting the desire to develop large scale industrial UCG plants,pilot level projects are presented using a new UCG method developed in Russia by Joint Stock Company Gazprom Promgaz.This method is distinct for its high controllability,stability,and energy efficiency.New,efficient technical solutions have been developed over the last 10-15 years and are patented in Russia.They guarantee controllability and stability of UCG gas production.Over one hundred injection and gas production wells have been operated simultaneously.Kreynin Efim Vulfovich 2012International Journal of Mining Science and Technology2012,22,4:6
3Free-range chicken eggs as a bioindicator of dioxin contamination in Vietnam,including long-term Agent Orange impact显示文摘PCDD/Fs contamination of free-range chicken eggs and soils from private Vietnam households was studied.The possibility of using free-range eggs as bio-indicators of dioxin contamination was considered as the soil-chicken-egg exposure pathway is considered to be the most sensitive exposure pathway of dioxins in soils to humans.A large territory from Dong Nai province in the south to Lao Cai province in the north was covered by the research.All analyses were performed by HRGC-HRMS method.PCDD/Fs levels in eggs from the majority of southern households exceeded the EC limit for eggs and egg products(2.5 pg WHO-TEQ2005 g^-1 lipid).Total TEQs ranged from 0.4 to 361 pg WHO-TEQ2005 g^-1 lipid in eggs and from 0.1 to 1272 pg WHO-TEQ2005/g in soil.2,3,7,8-TCDD contribution was statistically significantly higher in both eggs and soils in sprayed with Agent Orange areas,indicating its long-term impact.In order to assess within site variation,a total of 62 individual eggs from 14 private households were analyzed.Mean relative standard deviation of total TEQ values in individual eggs within the separate households was 27%.Rather good correlation of PCDD/Fs concentration in eggs and respective soils was observed for all dioxin congeners and for hexa-and hepta-furans(except for 1,2,3,7,8,9-HxCDF).Higher bioaccumulation for lower chlorinated congeners was confirmed.The current study of using eggs as bioindicators for large POPs contaminated sites may be suggested as a policy approach to evaluate human exposure to dioxin/POPs contaminated sites for known or suspected contaminated areas.Anastasia D.Kudryavtseva Andrey A.Shelepchikov Efim S.Brodsky 2020Emerging Contaminants2020,6,1:3
