Preface to Special Topic: Papers from the 2009 Conference on Advances in Microfluidics and Nanofluidics, The Hong Kong University of Science & Technology, Hong Kong, 2009

The inaugural conference on Advances in Microfluidics and Nanofluidics was held at the Hong Kong University of Science and Technology on 5–7 January 2009 and brought together leading researchers from across a wide variety of disciplines from North America, Europe, Asia, and Oceania. This Special Topic section forms the second of the two issues dedicated to original contributions covering both fundamental physicochemical aspects of microfluidics and nanofluidics as well as their applications to the miniaturization of chemical and biological systems that were presented at the conference.In the last five years, we have observed rapid growth in the microfluidics and nanofluidics community in Asia, owing largely to the substantial strategic investments by both government and industry in the region to promote the microfabrication and nanotechnology sectors.¹ The organization of a regular meeting focusing on activities in the Asia-Pacific rim region was, therefore, timely, particularly to enhance dissemination of research of the highest quality within the region and to promote collaboration between researchers in the Asian community with their counterparts from Europe and the USA.Biomicrofluidics is, therefore, proud to be closely involved with the organization of the first of such conferences, Advances in Microfluidics and Nanofluidics 2009, which was kindly hosted by the Hong Kong University of Science and Technology (HKUST). As reported in the preface to the first of the two issues dedicated to invited reviews and original contributions associated with the conference,² the meeting, which took place over three days in the breathtaking HKUST campus overlooking Clearwater Bay in Hong Kong, was a tremendous success. Together with our colleagues, the Biomicrofluidics editors are busy putting in place arrangements for a follow-up meeting in January 2011. Given the overwhelming response and positive feedback we’ve had to date, we believe that Advances in Microfluidics and Nanofluidics will form a regular event in the calendar of the Asian microfluidics and nanofluidics community in the future.It was particularly pleasing to observe the translation of fundamental and theoretical work into advanced applied chip-based platforms for a variety of practical chemical and biological applications in the talks presented at the conference. The collection of articles in this second part, in fact, provides a gist of the flavor of the multidisciplinary research spanning the entire fundamental to applied research spectrum, which is exactly the scope which the journal intends to cover.Electrokinetics continues to be a dominant theme in this issue and within the microfluidics and nanofluidics community. The article by Ng et al.³ provides experimental evidence that might put to rest a longstanding area of debate within the electrokinetics community on the role of Faradaic charging in driving electro-osmotic flow, first proposed by Ben and Chang.⁴ In other electrokinetics papers, the role of interfaces is explored, for example, electrowetting on the superhydrophobic nanostructured surfaces of a lotus leaf⁵ and droplet manipulation in an immiscible dielectric liquid continuum under an electric field.⁶In addition, the characterization of the surface charge density of the nanopores etched in organic foils is reported by Xue et al.,⁷ which provides a deeper understanding of the mechanisms by which ions are transported in nanochannels, whereas Wei and Hsiao⁸ present a stochastic simulation to model the condensation of linear polyelectrolyte molecules under electric fields, in which they show the marked increase in the mobility of the polyelectrolyte chain during its unfolding in free-solution electrophoresis.Continuing along the theme of numerical simulations, particulate transport in converging-diverging microchannels was studied using a Lagrangian-Eulerian finite-element model,⁹ and slip arising in Couette flows over superhydrophobic surfaces was studied using a hybrid multiscale simulation that interfaces molecular dynamics simulations in the near-wall region with the continuum fluid model in the bulk.¹⁰ In other numerical studies, drop coalescence¹¹ and nanotube transport¹² were studied.Complementing these fundamental studies is the use of multiphase flows in microfluidic channels to engineer scaffolds for tissue engineering in which the bubbles trapped in liquid droplets transported in microchannels were employed to produced the pores of the scaffold.¹³ Other practical microfluidics applications, such as chip-based enhancement of DNA hybridization through a genetic-bead-based protocol¹⁴ and an automated ELISA chip for chemical-biological analysis with an enhancement in the detection range and time,¹⁵ also constitute papers in this Special Topic section.We hope you enjoy reading the papers in this Special Topic section and that it provides you with a feel for the broad multidisciplinary spectrum across fundamental and applied microfluidic and nanofluidic research that the conference, as well as the journal, intends to span. Do watch out for the conference announcement for the next Advances in Microfluidics and Nanofluidics meeting in 2011 on the Biomicrofluidics website (http://bmf.aip.org)—hope to see you there!

香港经济转型与深港双城结构

一般而言,我们将1960年以来的国际分工称为新国际分工(theNew International Divisional Divisionof labor NIDL),这是与殖民化国际分工相对而言的,它是以劳动密集型产业向发展中国家转移为代表,引起国际分工质的变化,从而重构发展中国家(地区)与发达国家(地区)生产联系的劳动地域分工理论。按照新国际分工理论,大多数企业家会试图通过分散其加工程序以谋取最大的利益。他们将生产程序分散到劳动力廉价的国家和地区以降低其产品的总生产成本。恩莱特等用一个十

香港离岛生态的特征和重要性

郊野是香港的宝贵资产。为了保护郊野资源的完整性,香港早在1976年便通过郊野公园法例。法例规定,在郊野公园的范围内,一切破坏环境和损害生态的活动都禁止进行。时至今日,已共有23个郊野公园先后成立。这些郊野公园大部分是坐落于内陆上,离岛的郊野却没有得到相同程度的保护。为了了解香港离岛生态的特征及其重要性并为生态保育工作提供数据,作者制作了3个离岛(它们分别是南丫岛南部、东龙洲和蒲台岛)的生态地理信息系统。资料显示,因为水土条件恶劣,离岛的生物多样性并不高。离岛的主要植物群落是低灌林、草地或其混合体(共占7.67%)。植被的垂直分布明显,低灌林和草地多见于山坡的上半部,而小片的高灌林和树林或可在山坡的下半部或较荫蔽的山谷找到。离岛的生态虽然结构简单,但却为一些受保护和稀有的动、植物提供了仅存的生存环境。因为离岛的生态较脆弱而容易受破坏,政府应将一些具生态价值的离岛划定为郊野公园,以致离岛的生态能得到更有效的保护和管理。

粤港澳三地政府科技奖励体系比较

比较分析粤港澳三地政府科技奖在奖项设置、参评方式、奖励对象、奖励等级与数量、评审组织、奖励方式等方面的异同和特点,发现广东省科技奖的行政色彩较为浓厚,政府部门作为主要提名者难以实质性落实提名责任,丰厚的奖励派生待遇偏离了科技奖励荣誉本身,缺乏对青年科技工作者的引导激励;澳门特区政府的科技奖与广东省科技奖较为相似,但其较为注重引导鼓励青年群体开展科技创新;香港特区政府的科技奖励注重发挥市场及社会组织的参与和管理作用.比较分析结果对完善广东省政府科技奖励体系的主要启示为:明晰非市场化激励机制和政策导向作用,进一步优化奖励对象结构,注重对青年科技人员的奖励,落实提名者责任,突出奖励的荣誉性和价值导向,实现与社会科技奖励的互补和协同发展.
