摘要：In this paper I describe research activities in the field of optical fiber sensing undertaken by me after leaving the Applied Optics Group at the University of Kent. The main topics covered are long period gratings, neural network based signal processing, plasmonic sensors, and polymer fiber gratings. Ⅰ also give a summary of my two periods of research at the University of Kent, covering 1985-1988 and 1991-2001.

摘要：The study carried out here was focused on developing conventional monolithic controlled release matrix tablet of Atorvastatin calcium using carbomer as release controlling polymer. This system ensures the drug release at the alkaline pH region where the drug has got maximum solubility. Further the study was concentrated on comparing the impact of gelling agent polyvinyl pyrrolidone on drug release. Quality by design tools were considered during formulation development and the polymer concentrations were optimized adopting the statistical tool, design of experiments (DoE). The optimized formulation of present study exhibited desired controlled drug release characteristics in the alkaline pH conditions and at acidic environment the drug dissolution was minimal as intended.

摘要：A methology is described for the synthesis of novel temperature-responsive interpenetrating polymer network (IPN) hydrogels with poly(2-acrylamido- 2-methylpropane sulfonic acid) (PAMPS) as a tightly crosslinked 1st network, temperature-responsive poly(acrylamide-co-N-(1,1-dimethyl-3-oxobutyl)- acrylamide) (P(AM-co-DAAM)) with low cost as a lossely crosslinked 2nd network. The structure and morphology of the IPN hydrogels were characterized by FTIR, TGA and SEM, and the results indicated that PAMPS network introduced P(AM-co-DAAM) hydrogels have large, thermally stable and interconnected porous network. The properties of the IPN hydrogels, which include: swelling capacity, equilibrium swelling/deswelling ratio, temperature- responsive behavior, and the dwelling kinetics as specific temperature, were investigated carefully. Results showed that the obtained IPN hydrogels displayed a controllable equilibrium swelling/deswelling behavior and possessed remarkable thermosensitivity. In addition, the results also indicate that the incorporation of the hydrophobic groups DAAM has a big effect on the LCST of the IPN hydrogels. Consequently, these novel temperature-responsive IPN hydrogels with low cost and slow-releasing performance would be promising for potential applications, such as environmental catalysis, water treatment, and agriculture.

摘要：近年来,FRP(Fibre Reinforced polymer)用于加强修复钢结构及铝合金结构取得了较多应用。本文首先总结回顾了钢结构、混凝土结构与FRP粘贴连接节点界面应力的弹性分析方法,然后总结了考虑胶水塑性变形的粘结-滑移分析及不同的强度设计准则。文中还总结了不同受力形式下,钢或铝合金与FRP组合结构构件的受力性能,包括受拉、受弯、受压等工况。已有的试验及有限元方法主要分析了FRP和胶水的材料性质、FRP粘贴位置和范围、胶水层厚度等因素对组合构件的强度和破坏模式的影响,并依据试验结果和理论分析,提出了有效粘贴长度的概念。简要回顾了FRP加固后钢结构或铝合金结构的疲劳性能,以及航空领域和相关领域的研究情况。最后提出了FRP用于加固金属结构的几点待研究或完善的问题。

摘要：分别叙述了三种在电子制造过程中新的工艺,它们都不使用传统的焊料,可以大大地简化电子产品的制造方法。采用这三种工艺制造出的电子产品将会比之前的非焊接的电子产品(比如导电胶)具有更高的可靠性和可行性。这三种工艺都采用了和现在流行的PCB工艺相反的工序,先放置好芯片再进行布线。无论是"Chip in polymer"、奥克姆工艺还是逆序加成工艺都使用的是目前常见的、低风险的、成熟的核心技术。它们都是在埋入芯片之后才用铜进行连接,因此不需要传统的PCB,这三种工艺更适用于无论是民用还是军用的高密度、高可靠性、高性能和对环境损害更小的电子制造。它们相比于传统的PCB制造有更简化的设计、更少的工序、简化的供应链以及其它更多的优势。
