受應力拉伸時,橡膠溫度明顯上升;縮放回原長,橡膠溫度驟降。由文獻得知橡膠內部具有特殊的鍵鍊結構,在一般的情況下,交鏈分子糾結成一團,狀態複雜;受外力拉伸時,交鏈分子依橡膠長度之增加而伸展,排列較為整齊,狀態之複雜度減小。根據熱力學第一定律,當內能變化為零,則外力作功會造成能量變化。在定溫之下,橡膠內能變化為零,當其受應力拉伸,使其內部交鏈分子排列複雜度降低,造成橡膠熵值減小,而有能量(dQ=TdS)的釋出。測量此一能量dQ 變化,即可計算出熵與狀態數之變化The temperature of rubber rises as it is stretched, its temperature comes back again while it restores to its original length. It is known that the rubber is consisted of long-chain molecules, the long-chain molecules strangle each other at normal state, however, they become more order when the rubber is stretched. Based on the 1st law of thermodynamics dU=dQ+dW, The deformation caused by applied force supplies energy to the rubber and reduce its entropy, the heat dQ (=TΔS) released by the reduction of entropy causes the temperature rise of rubber as dU=0. We report the study on the correlation of thermal properties and the molecular network in rubber, from the measurements of temperature change, the changes of entropy and the changes of states’ number were estimated.

Synthesis, Characterisation, and Temperature-sensitivity of Hydroxyl-Terminated Poly(N-isopropylamid
Background:\r Delivery of anticancer drugs in vivo can be achieved by using targetspecific\r drug carriers of various types – e.g. microspheres and liposomes –\r which can be applied intravenously, or subcutaneously via a hypodermal\r patch, etc. as appropriate to the type of drug carrier employed. Recently,\r interest has surged in the usage of amphiphilic polymeric micelles for this\r purpose, as they prove superior to other drug carriers in many ways. They\r have highly-hydrated hydrophilic shells, and hydrophobic cores wherein\r hydrophobic anticancer drugs such as adriamycin can be encapsulated\r during transport in the blood. Their main advantages include their\r smallness of size – enabling them to elude capture by the\r reticuloendothelial system (RES) – their stability in the bloodstream as\r shown in their low critical micelle concentration (CMC) values, their\r passive targeting of tumour sites via the enhanced permeability and\r retention (EPR) effect, and their ability to integrate an active targeting\r mechanism, e.g. antibody-antigen recognition, pH-sensitivity, etc.

關於1234-,2143-,3412-Avoiding Involution排列的統計量探討
令Sn 為{1,2,…,n}任意排列所成的集合,π ? Sn 為其中的一個元素,我們記π = (π(1), π(2),…, π(n))。今給定π ? Sn ,若對所有i,1? i ? n,都有π (π (i)) = i 時,我們稱π 為involution。假設π ? Sn ,並給定σ ? Sm (m ? n),當π 中任取m 項,其大小關係的順序都和σ 不同,我們稱π 避開σ,或稱π 是一個σ-avoiding 排列。在這篇報告中,我們主要分析了2143-avoiding involution,1234-avoiding involution,和3412-avoiding involution 中的一些統計量,給出了十數個結果與幾個猜想。Let Sn be the set of permutations on {1,2,…,n} and π ? Sn be an element in Sn. Denote π as π = (π(1), π(2),…, π(n)). We say that π is an involution if π(π(i)) = i for every i, 1? i ? n. Given π ? Sn and σ ? Sm (m ? n) , we say that π avoids σ (or π is an σ-avoiding permutation) if π does not contain any m-term subsequence in the order of σ. In this paper, we discuss some classic statistics on 2143-avoiding involutions, 1234-avoiding involutions and 3412-avoiding involutions. We get many new results in this field and give some interesting conjectures.

六種自行合成出來的聯吡啶釕錯合物Ru(bpy)₃、Ru(bpy)₂(phen) 、 Ru(bpy)₂dcbpy、Ru(phen)₃、Ru(phen)₂(bpy)、Ru(phen)₂dcbpy 及商用染料N3-dye,被成功的做成光敏性太陽能電池。光電流的產生率可由IPCE (incident photon-to-current conversion efficiency) 的測量可知。此類釕錯合物可以物理吸附或化學鍵結於TiO₂奈米粒子上。IPCE 的大小可以用來探討不同吸附方式的釕錯合物轉換光電流的效率。在物理吸附上Ru(phen)₂(bpy)的效率最好。化學鍵結的以N3 Dye 最好,我們合成的錯合物以Ru(bpy)₂dcbpy 較佳。此種以TiO₂奈米結構為承載基材的太陽能光電池(Dye-Sensitized Solar Cell),染料仍以商用染料 N3-dye 最佳。本研究發現物理吸附的Ru complexes 也可產生光電流,若能最佳化,將可簡化染料錯合物之合成。
Six ruthenium complexes, Ru(bpy)₃, Ru(bpy)₂(phen), Ru(bpy)₂dcbpy, Ru(phen)₃, Ru(phen)₂(bpy), and Ru(phen)₂dcbpy were synthesized. These Ru complexes and N3 dye have been incorporated into the dye-sensitized solar cell system. The solar energy conversion of the ruthenium complexes were measured and converted to IPCE (incident photon-to-current conversion efficiency). There complexes were either chemically bonded or physically absorbed onto the nano-sized TiO₂ particles. The IPCE were utilized to compare the photon-to-current efficiency of these Ru complexes. Among the physical-absorbed dyes, Ru(phen)₂(bpy) has the highest IPCE. For chemical-absorbed dyes, the commercial N3 dye is still the best. Among the complexes synthesized in this research that are chemical-absorbed, Ru(phen)₂dcbpy has the highest IPCE
The commercial N3 dye has the highest IPCE in the dye-sensitized TiO₂nanoparticle solar cell. We found that physically absorbed dye can convert photon to current. With better solar cell assembly, physically absorbed dye can have the same conversion efficiency as N3 dye.

藉由lotus effect 之原理來探討超疏水性表面的製備
超疏水表面(superhydrophobic surface)因其自我清潔效果在近年來引起廣泛的研究及探討,目前世界各大公司皆積極投入自潔性產品(超疏水表面)的研發,但是截至目前為止除了塗料及織物有產品外,其他尚在研發階段。降低表面能及增加表面粗糙度為製作超疏水性表面的兩種方法。本實驗我們針對使用不同方法去仿照自然界植物「蓮花效應」,將二氧化矽粒子適當的分佈在基材表面,以增加粗糙度,製造出超疏水性表面。我們發現鍛燒會使其二氧化矽粒子黏聚在一起,對接觸角的增加無幫助。而在溶膠凝膠的配置過程中直接加入OTS(Octadecyltrichlorosilane),並利用光散射儀比較二氧化矽奈米顆粒的平均粒徑及粒徑分佈隨時間變化的情形,一段時間後發現會有明顯大顆粒沉澱,塗佈在玻璃基材表面後容易脫落,不適合往後實驗或其他用途。而以氨水催化的溶膠凝膠以不同流速滴入TEOS (Tetraethylorthosilicate,四乙氧基矽)對接觸角的影響也不大。最後我們利用砂紙在基材表面上刷磨,可以使二氧化矽粒子分佈均勻,明顯增加接觸角。塗佈速率的改變搭配疏水性矽烷單分子膜的改質,我們已可以製造出159°的超疏水性表面。Superhydrophobic surfaces are generally made by lowering the surface energy and increasing the surface roughness. In this experiment, we use different methods of spreading silicon dioxide nanoparticles properly on the surface in order to increase the surface roughness and also make superhydrophobic surfaces. In the beginning, we find that the calcinations can cause its silicon dioxide nanoparticles to stick together instead of increasing the contact angles. Then, add OTS (Octadecyltrichlorosilane) directly to manufacture process of sol-gel, and observe the situations of the average length and the spread of silicon dioxide nanoparticles with the time goes by. After a period of time, we will discover that many obvious big particles deposit and spin-coating on the glass surfaces flop easily. Hence, this phenomenon is n’t proper for the following experiments or other uses. However, the contact angles have nothing to do with dropping the sol-gel catalyzed ammonia to TEOS(Tetraethylorthosilicate) by different flowing rates. Finally, it is crucial for us to use the sandpapers to brush on the surfaces because it may cause the silicon dioxide nanoparticles to spread well and obviously increase the contact angles. Combining the silicon dioxide surfaces with the change of spin-coating rate and the cover with hydrophobic SAM, we have made the superhydrophobic surfaces of 159°.

The purpose of this study is to find the best colored silkworm cocoons by mixing different consistency of pigments to feed silkworms. At the same time, this study wished to explore how the different consistency of pigments influenced the silkworm cocoons that the silkworms produced. Besides, in order to find the better association between pigments and Baume degrees, this study exposed the cocoons under different lights, washed with different detergents and take observations of micro-structure of the cocoons. The results of this study are as follows: using the nano-pigments 60 ml in different density, that is, red:1.048, blue:1.058, and yellow:1.039, then mixed them with silkworms’ forage 30g , in this way, best successful ratio to get colored cocoons, desired high visual effects in color, well distribution, long duration and strong resistance to detergents agents are obtained. In addition, we can still get glossy appearance and fine cocoons; the wire diameter is about the size of 19.87μm. On contrast, feeding with the ordinary pigments, the degree of colored silk is better than feeding with the nano-pigments, but the appearance of cocoons are rough and the wire diameter is about the size of 21.51μm.

太陽短期活動對地球磁場與大氣溫度異常的影響
This study analyzed how short-term solar activities interact with the earth atmosphere, by using two statistic methods: Diffusion Entropy Analysis (DEA), and Standard Deviation Analysis (SDA). Since solar activities influence the Earth atmosphere in its radiating heat and magnetic field, we use DEA and SDA to calculate the exponents, H and δ, of the scaling law in three time series: “the intensity of solar flare” (representing by SOLAR H-alpha flare index), “magnetic anomaly of magnetosphere” and “sea surface temperature anomaly”. The values of H and δ show the time memory and correlative relationship between the event and next event happening in time series. When H = δ = 0.5, events occur in random. When 0.5
