Unidirectional rotary motion in a molecular system.

The conversion of energy into controlled motion plays an important role in both man-made devices and biological systems. The principles of operation of conventional motors are well established, but the molecular processes used by 'biological motors' such as muscle fibres, flagella and cilia to convert chemical energy into co-ordinated movement remain poorly understood. Although 'brownian ratchets' are known to permit thermally activated motion in one direction only, the concept of channelling random thermal energy into controlled motion has not yet been extended to the molecular level. Here we describe a molecule that uses chemical energy to activate and bias a thermally induced isomerization reaction, and thereby achieve unidirectional intramolecular rotary motion. The motion consists of a 120 degrees rotation around a single bond connecting a three-bladed subunit to the bulky remainder of the molecule, and unidirectional motion is achieved by reversibly introducing a tether between the two units to energetically favour one of the two possible rotation directions. Although our system does not achieve continuous and fast rotation, the design principles that we have used may prove relevant for a better understanding of biological and synthetic molecular motors producing unidirectional rotary motion.     

铅烷发生的酸性模式与碱性模式的对比研究

用FI－HG－AAS系统对K2Cr2O7体系铅烷发生的碱性模式与酸性模式进行了对比研究，观察反应中反应物摩尔量与铅烷产率关系后发现酸性模式与碱性模式有相同的规律，采用高浓度K2Cr2O7氧化，其还原产物Cr(Ⅲ）会生成CrBn沉淀，严重吸附铅离子，导致铅信号下降。     

纵卷叶螟绒茧峰的畸形细胞

以水稻重要害虫稻纵卷叶螟和其主要寄生天敌从纵卷叶螟绒茧蜂为研究对象，对它们之间相互作用的内部机制进行了初步研究，结果表明纵卷叶螟绒茧峰在寄主体内寄生时，其胚膜的局部区域 解成单个细胞释放到寄主的血淋巴中，形成畸形细胞，起初畸形细胞的数量在１２０个左右，随着寄生蜂幼虫的不断发育，畸莆细胞的体积逐渐增大，当寄生蜂幼虫老熟啮出时，畸表细胞的直径已从最初的３０μｍ增大到２５０μｍ体积增大了５００多倍，但数     

Technology and the Myth of ‘Natural Man’

The main suggestions and objections raised by Don Ihde and Charles Lenay to my ‘Technology and the body: the (im)possibilities of re-embodiment’ are summarized and discussed. On the one hand, I agree that we should pay more attention to whole body experience and to further resisting Cartesian assumptions in the field of cognitive neuroscience and philosophy of cognition. On the other hand, I explain that my account in no way presupposes the myth of ‘natural man’ or of a natural, delineated body from before the fall into technology.
