1A history of high-power laser research and development in the United Kingdom显示文摘The first demonstration of laser action in ruby was made in 1960 by T.H.Maiman of Hughes Research Laboratories,USA.Many laboratories worldwide began the search for lasers using different materials,operating at different wavelengths.In the UK,academia,industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications.This historical review looks at the contribution the UK has made to the advancement of the technology,the development of systems and components and their exploitation over the last 60 years.Colin N.Danson Malcolm White John R.M.Barr Thomas Bett Peter Blyth David Bowley Ceri Brenner Robert J.Collins Neal Croxford A.E.Bucker Dangor Laurence Devereux Peter E.Dyer Anthony Dymoke-Bradshaw Christopher B.Edwards Paul Ewart Allister I.Ferguson John M.Girkin Denis R.Hall David C.Hanna Wayne Harris David I.Hillier Christopher J.Hooker Simon M.Hooker Nicholas Hopps Janet Hull David Hunt Dino A.Jaroszynski Mark Kempenaars Helmut Kessler Sir Peter L.Knight Steve Knight Adrian Knowles Ciaran L.S.Lewis Ken S.Lipton Abby Littlechild John Littlechild Peter Maggs Graeme P.A.Malcolm OBE Stuart P.D.Mangles William Martin Paul McKenna Richard O.Moore Clive Morrison Zulfikar Najmudin David Neely Geoff H.C.New Michael J.Norman Ted Paine Anthony W.Parker Rory R.Penman Geoff J.Pert Chris Pietraszewski Andrew Randewich Nadeem H.Rizvi Nigel Seddon MBE Zheng-Ming Sheng David Slater Roland A.Smith Christopher Spindloe Roy Taylor Gary Thomas John W.G.Tisch Justin S.Wark Colin Webb S.Mark Wiggins Dave Willford Trevor Winstone 2021High Power Laser Science and Engineering2021,9,2:5

3船只排放物对欧洲空气质量及酸性沉降造成的影响显示文摘一个名为'STOCHEM'的三维拉氏化学传输模型被用于描述2000年气候条件下国际海运活动产生的SO_2、NO_x、VOCs和CO排放造成的欧洲大西洋沿岸区域性酸性沉降和臭氧空气质量影响的状况。该模型得出的从西南海域到不列颠群岛和布列塔尼水域国际海运活动产生的硫沉降总量高达200mg/m^2·a。夏季国际海运活动对表层臭氧浓度的影响在爱尔兰、布列塔尼和葡萄牙高达约6ppb。在欧洲,海运活动产生的排放物是一种对酸性沉降和臭氧空气质量造成影响的外部因素,并且如果要在将来达到严格的沉降及空气质量目标,就需要采取一系列控制措施。Richard G.Derwent David S.Stevenson Ruth M.Doherty William J.Collins Michael G.Sanderson Colin E.Johnson Janusz Cofala Reinhard Mechler Markus Amann Frank J.Dentener 许天虎 2005AMBIO-人类环境杂志2005,34,1:2

7Endoproteolytic cleavage as a molecular switch regulating and diversifying prion protein function显示文摘The prion protein(Pr P),through misfolding,is widely known for its causative role in prion diseases,which are transmissible neurodegenerative diseases of humans and animals.There is still no defined function assigned to Pr P,especially in the central nervous system,despite many studies in this area.Proposed functions are protean and include signal transduction,neuroprotection,neurogenesis,neuritogenesis,metal-ion homeostasis,memory formation and consolidation,as well as circadian rhythms(Nicolas et al.,2009).PartCathryn L.Haigh Steven J.Collins 2016Neural Regeneration Research2016,11,2:1

10改善聚酯织物的舒适性显示文摘普通聚酯的很多性能,如强力、耐磨、回弹性和尺寸稳定性均能满足各种最终用途的需要。但它也有不足之处,如疏水性和亲油性,它会集结静电,并且难以除去油污渍。在感觉方面聚酯织物则不如天然纤维织物舒适。消费者评论合成纤维的主要局限性是:不自然的手感,令人不悦的热的感觉,织物与皮肤接触时的冷湿感、缺乏吸湿性、异样的皮肤接触感及与静电相关的问题。很多年来进行了许多研究和开发工作以改善这些性能。本文主要述及舒适性。 对于舒适性难以下定义和用数量表示。任何对服装舒适性的分析,必须考虑到物理、心理、生理方面。控制舒适性的重要因素是通过织物传递热量、湿气和空气。主观组成部分,如尺寸、合身性、柔软性、手感和静电发生也应考虑在内。需要穿着试验和实验室测试。 服装舒适性是个复杂的和引起争论的问题。它已被广泛地评论并作为讨论的主题。服装舒适性可通过各种技术得到改善,包括服装设计、织物结构、纱线结构、纤维变性、各种类别纤维的混纺和有关这方面的专题整理。纤维变性可以通过化学方法完成,或通过纺丝工艺以完成变化,如改变纤维横截面。这些方法可以各别使用或结合使用。以下部分应用专门整理和化学变性评论了某些用于改善聚酯舒适性的工艺。应强调的是。S.Haig Zeronian Martha J.Collins 王秀玲 1989印染1989,15,5:0
11Using Inductance as a Tuning Parameter for RF Meta-atoms显示文摘The resonant frequency of metamaterials structured with split ring resonator(SRR) meta-atoms is determined primarily through the capacitance and inductance of the individual meta-atoms. Two designs that vary inductance incrementally were modeled, simulated, fabricated, and tested to investigate the role inductance plays in metamaterial designs. The designs consisted of strategically adding sections to the SRR to increase the inductance, but in a manner that minimized capacitance variations. Each design showed a shift in resonant frequency that was proportional to the length of the added section. As the length of each section was increased, the resonant frequency shifted from 2.78 GHz to 2.18 GHz.Derrick Langley Ronald A.Coutu Peter J.Collins 2012Nano-Micro Letters2012,4,2:0
12微波辅助有机合成——应用于药物开发显示文摘多年来,药物开发的瓶颈一直是在合成这个步骤上,其原因在于用以驱使合成反应的方式一直是传统的热力加热。而最新技术的开发让微波成为加热反应更有效的方法。那些本需要几小时,甚至几天才能完成的合成反应现在只需几分钟,因而让有机化学家们有更多的时间用以分析和优化他们的反应,使他们更有创造性。微波合成包括很多有优点,例如反应速率的提升,产率的提高和“更干净”的化学。由CEM所开发的新型微波环形单膜腔把所有传统合成设备的优点以及微波瞬间加热的能力结合于一个简洁但具有强大作用的仪器上。Abbott实验室(芝加哥、伊利诺斯)使用此仪器执行了针对药物开发的合成反应。化学家们发现环形单膜腔辅助有机合成的好处是在传统方法和从前的微波方法上的大量改良。Michael J.Collins 刘威志 2003生命科学仪器2003,1,6:0
13地球演化历史中氧逸度变化对壳幔循环启动、风化和超大陆循环的指示显示文摘We apply a zircon redox index to a global compilation of detrital zircons to track the variation of oxidation state,expressed asΔFMQ,through Earth's history.Those from I-type rocks,which comprise mantle and crustal igneous protoliths,including tonalite–trondhjemite–granodiorites(TTGs),generally have a high oxidation state(ΔFMQ>0).In contrast,zircons from igneous rocks derived from supracrustal source rocks(S-type)are commonly reduced(ΔFMQ<0).With the probability density function derived from the Gaussian-Kernel-Density-Estimation,we use the maximum likelihood estimation(MLE)to distinguish Stype from I-type zircons through Earth's history using zircon redox.Voluminous S-type magma production shows a ca.600 Ma cyclicity that is closely related to the supercontinent cycle.We link a cyclic drop in redox values after 2.6 Ga to periodic S-type magma generation associated with burial and melting of metasedimentary rocks during supercontinent assembly and amalgamation.TheΔFMQ of the detrital zircons rise at~3.5 Ga followed by a consistent averageΔFMQ>0 over the last 3 Ga.Given that the redox state of magmas is independent of crustal thickness and silica variation,and elevated values are likely more closely related to tectonic setting,we suggest that the consistent averageΔFMQ>0 from ca.3.5 Ga onwards relates to recycling of oceanic lithosphere back into the mantle in what eventually became established as subduction zones.The more reduced magmas associated with sedimentary sources,became established at 2.6 Ga,presumably in response to continental rocks rising above sealevel,and follow peaks of productivity associated with the supercontinent cycle.王瑞 邬绍宸 Roberto F.Weinberg William J.Collins Peter A.Cawood 2024Science Bulletin2024,69,1:0

15我还有很多显示文摘我的承诺我的病人,有一个人永远无法忘怀:莎拉·贝德森。我是在骨科肿瘤部遇上她的。莎拉当时才十八岁,貌美如花,但生命危在旦夕,骨盆左侧长了个骨骼肉瘤,情况并不乐观。比尔·柯莱默是主治医师。我们得告诉莎拉:她要活下去的唯一办法,是动大手术,切除左腿以及部分骨盆。MICHAL J.COLLINS 2006跨世纪(时文博览)2006,0,2:0
