| 1 | Generating optical orbital angular momentum at visible wavelengths using a plasmonic metasurface显示文摘Light beams with a helical phase-front possess orbital angular momentum along their direction of propagation in addition to the spin angular momentum that describes their polarisation.Until recently,it was thought that these two‘rotational’motions of light were largely independent and could not be coupled during light–matter interactions.However,it is now known that interactions with carefully designed complex media can result in spin-to-orbit coupling,where a change of the spin angular momentum will modify the orbital angular momentum and vice versa.In this work,we propose and demonstrate that the birefringence of plasmonic nanostructures can be wielded to transform circularly polarised light into light carrying orbital angular momentum.A device operating at visible wavelengths is designed from a space-variant array of subwavelength plasmonic nano-antennas.Experiment confirms that circularly polarised light transmitted through the device is imbued with orbital angular momentum of 62'(with conversion efficiency of at least 1%).This technology paves the way towards ultrathin orbital angular momentum generators that could be integrated into applications for spectroscopy,nanoscale sensing and classical or quantum communications using integrated photonic devices. | Ebrahim Karimi Sebastian A Schulz Israel De Leon Hammam Qassim Jeremy Upham Robert W Boyd | 2014 | Light(Science & Applications)2014,3,1: | 39 |
| 2 | 陶瓷部件的浆料打印快速成型(英文)显示文摘采用Sanders公司的四打印头快速成型机进行了陶瓷部件的浆料打印成型实验 ,实际测试了所用四打印头快速成型机的打印工作条件 ,考察了石蜡和挥发性介质两种浆料技术路线 ,并采用石蜡为介质制备了钛酸钡陶瓷浆料 ,研究了其流变性能 .实验表明 ,虽然偶联剂的加入可以降低石蜡介质浆料的粘度 ,但是粘度足够低的可打印浆料的固相含量太低 [约 3 % (involume)以下 ] ,打印成型后不能完全烧结 ,因此 ,要通过打印成型出可完全烧结的陶瓷部件便只能采用挥发性液体作为浆料介质 。 | 王树海 Jang J H Schulze W A Pilgrim S M | 2001 | 硅酸盐学报2001,29,4: | 10 |

| 5 | 前列腺癌印记基因表达的特殊变化一前列腺癌发展和表观遗传调控的预示显示文摘DNA高甲基化和低甲基化,EZH2过度表达以及组蛋白修饰等表观遗传失调与前列腺癌的发展相关。DNA甲基化,EZH2和组蛋白修饰同时也确保了至少62种印记基因的亲缘特异性单等位基因的表达。尽管我们可以据此得到一个非常有趣的推断:表观遗传失调可能涉及到印记基因,但在前列腺癌中仅证明了IGF2的表达改变。一篇研究前列腺癌印记基因的文章和数据库显示,尽管表观遗传机制在全局上有干扰,但绝大多数印记基因表达没有变化。相反,选择性遗传和表观遗传的改变似乎抑制了印记基因亚网络,从而有可能在前列腺细胞中通过P13K/Akt途径限制细胞的生长,调节雄激素反应和调控分化。IGF2异常调控可能导致前列腺癌的早期改变,然而该印记基因网络的失活却与癌症的发展有关。 | Teodora Ribarska Klaus-Marius Bastian Annemarie Koch Wolfgang A Schulz | 2012 | Asian Journal of Andrology2012,14,3: | 4 |

| 7 | National Forest Inventories capture the multifunctionality of managed forests in Germany显示文摘Background:Forests perform various important ecosystem functions that contribute to ecosystem services.In many parts of the world,forest management has shifted from a focus on timber production to multi-purpose forestry,combining timber production with the supply of other forest ecosystem services.However,it is unclear which forest types provide which ecosystem services and to what extent forests primarily managed for timber already supply multiple ecosystem services.Based on a comprehensive dataset collected across 150 forest plots in three regions differing in management intensity and species composition,we develop models to predict the potential supply of 13 ecosystem services.We use those models to assess the level of multifunctionality of managed forests at the national level using national forest inventory data.Results:Looking at the potential supply of ecosystem services,we found trade-offs(e.g.between both bark beetle control or dung decomposition and both productivity or soil carbon stocks)as well as synergies(e.g.for temperature regulation,carbon storage and culturally interesting plants)across the 53 most dominant forest types in Germany.No single forest type provided all ecosystem services equally.Some ecosystem services showed comparable levels across forest types(e.g.decomposition or richness of saprotrophs),while others varied strongly,depending on forest structural attributes(e.g.phosphorous availability or cover of edible plants)or tree species composition(e.g.potential nitrification activity).Variability in potential supply of ecosystem services was only to a lesser extent driven by environmental conditions.However,the geographic variation in ecosystem function supply across Germany was closely linked with the distribution of main tree species.Conclusions:Our results show that forest multifunctionality is limited to subsets of ecosystem services.The importance of tree species composition highlights that a lack of multifunctionality at the stand level can be compensated by managing forests at the landscape level,when stands of complementary forest types are combined.These results imply that multi-purpose forestry should be based on a variety of forest types requiring coordinated planning across larger spatial scales. | Nadja K.Simons María R.Felipe-Lucia Peter Schall Christian Ammer Jürgen Bauhus Nico Blüthgen Steffen Boch François Buscot Markus Fischer Kezia Goldmann Martin M.Gossner Falk Hänsel Kirsten Jung Peter Manning Thomas Nauss Yvonne Oelmann Rodica Pena Andrea Polle Swen C.Renner Michael Schloter Ingo Schöning Ernst-Detlef Schulze Emily F.Solly Elisabeth Sorkau Barbara Stempfhuber Tesfaye Wubet Jörg Müller Sebastian Seibold Wolfgang W.Weisser | 2021 | Forest Ecosystems2021,8,1: | 2 |
