台灣柑橘產量富產且含有極高的營養價值，特別是果皮部分的營養更勝於果肉百倍以上。所以我們研究一套去除柑橘皮原有的嗆辣苦澀味的標準程序，再以處理過的柑橘皮為主要食材，開發出橘皮果醬、橘皮冰棒、涼拌橘皮、橘皮泡菜、糖漬橘皮巧克力和香酥甘梅橘皮等六道營養又美味的食物，以增進國人健康。新開發的食品經過「官能品評」問卷調查發現，民眾對柑橘皮食品的接受度非常高，但是去除橘皮嗆辣苦澀過程較費時，因此把去除嗆辣苦澀味的橘皮開發製成「冷凍橘皮料理」包，方便忙碌的現代人後續料理有很高的商業價值。最後嘗試使用近幾年流行的蔬果調理機「慢磨機」，提煉高品質的柑橘精油，提升柑橘皮全方位的利用價值，賦予台灣柑橘新的生命。

在本實驗，主要針對染料敏化太陽能電池的幾個變因來研究：染料、二氧化鈦膜厚度、電解質pH值、電解質組成比例以及光源照度對染料敏化太陽能電池光電轉換的影響。染料部份，採用了葉綠素、花青素、甲基藍、汞溴紅四種染料來比較，未染色為對照組。結果以甲基藍的敏化效率為最佳。在二氧化鈦薄膜厚度時，發現較薄的膜有較高的光電轉換效率。電解質pH值方面，發現酸性與中性的電流傳導效率較佳，鹼性則偏弱。此外，我們亦發現波長較短的光對染料敏化太陽能電池的電子電洞分離效果較佳。我們藉著控制電解質中碘化鉀的濃度，試著改進其電流傳導性能，結果發現在重量比(wt)為碘/碘化鉀/水(1/X/10)的系統之中，X約等於10-13有最佳的表現。在光度曲線方面，將自製太陽能電池以不同照度測試其電壓、電流值，電壓電流均隨照度增加而增加，發現電壓值在超過12000Lux時會突然下降。最後，我們測試了染料敏化太陽能電池的壽命。發現染料敏化太陽能電池的電壓／電流值在48小時內無削弱的趨勢。在補充實驗裡，我們嘗試了以二氧化鈦膜的大小為變因，觀察其光電流密度的改變情形，並比較各種鍍膜方式，以找出最經濟的鍍膜方法。

本研究探究網路及廣告所提芭樂葉多酚會抑制唾液澱粉?作用，但結果顯示多酚反能促進唾液澱粉?催化作用，可能因其與干擾澱粉?作用的金屬離子結合。我們不能因此推論攝取多酚會使人增胖，有其他機制和體內葡萄糖代謝有關而影響體重，如多酚能抑制細菌，科學雜誌「Nature」(註十)、(註十一)指出腸道中含促進養分吸收的厚壁菌門(Firmicutes)和抑制養份吸收的擬桿菌門(Bateroidetes)，二者合佔腸道菌種 92.6％，且肥胖動物體內 Firmicutes 量遠大於 Bateroidetes，而減肥過程中 Firmicutes 量漸少於 Bateroidetes 數量。據結果多酚對取自屠宰場的豬小腸液菌有抑制效果，因樣本來自肥胖豬隻腸液應富含 Firmicutes，芭樂葉多酚抑制到 Firmicutes，使人體吸收養分能力變差而減重。所以本研究發現多酚能促進減重的原因，應從腸道菌落消長來探討

This project aims to explore the potential of inexpensive in-situ deposition of niobium nitride nanowires to improve electrical conductivity. Transition metal nitrides are well known for attributes such as superconductivity, high melting point, simple structure as well as excellent electrical and thermal conductivities. In particular, niobium nitride possesses exceptional hardness and high reflectivity, as well as being a stable field emitter, making it well suited to applications as a cold cathode material. Niobium nitrides are formed by the uptake of nitrogen by niobium. This is achieved by the exothermic formation of an interstitial solid solution of nitrogen atoms in the bcc lattice of the niobium. Existing research has established the possibility of preparing niobium nitride by heating niobium in nitrogen or ammonia over a range of temperatures, by heating niobium pentaoxide and carbon in the presence of nitrogen as well as by chemical vapor deposition of other niobium compounds, nitrogen or hydrogen. For the purpose of this study, a two-step process was used for synthesis. The benefits of a two-step process over direct ammonolysis are apparent, from the greater degree of freedom pertaining to parameter determination. Additionally, characterization of niobium pentaoxide nanowires synthesize under similar conditions is also made possible by terminating the reaction earlier. NbN nanowires were synthesized by annealing niobium pentaoxide nanowires at 850 oC for 2 hours. Subsequent characterization was done using Raman Spectroscopy, X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The presence of NbN nanowires via the conversion of Nb2O5 was ascertained by the absence of sharp peaks at 1000 cm-1 for Raman Spectroscopy and XRD plots. Field emission (FE) properties and electrical properties of NbN nanowires were then measured. NbN nanowires were found to have a high turn-on voltage, stable and relatively good field emission characteristics, demonstrating its potential as a cold cathode material. No current saturation was observed for an applied electric field of 0 to 6.0 V/ μm (5). This suggests a low degree of contact resistance for nanowires produced by this method of annealing, since the passage of electrons is not obstructed. Hence there will only be a small voltage drop between the SiO2 substrate and NbN nanowires. Samples containing NbN nanowires were dislodged by ultrasound to form an aqueous suspension of nanowires. A drop of suspension was dripped onto gold-finger substrates, and current-voltage (I-V) measurements of resultant nanowire bridges were taken. NbN nanowire bridges display Ohmic properties, in comparison with Nb2O5 nanowires that are semiconducting. Nanowire bridges obtained by heat-drying were denser and had better electrical properties than those obtained by evaporation to dryness. NbN nanowire bridges display Ohmic properties, in comparison with Nb2O5 nanowires that are semiconducting. Further work would include varying the cooling processes to observe any changes or deformation. Additionally, niobium nitride nanowires can be hybridized with carbon nanotubes (CNTs). A more in-depth comparison between niobium oxide and niobium nitride nanowires is also proposed, along with exploration of the nitrification of other transition metals.

自然課本上有這樣一個問題：「在電路中，連接哪些溶液，可以形成通路，使燈泡亮？」上課中我們用 3 或 4 個新電池連接鹽水、自來水、肥皂水、醋、糖水、小蘇打水等水溶液，結果只有連接鹽水時，小燈泡有亮的情形，但是，不管小燈泡亮不亮，浸在鹽水中的電線（接電池負極的那端）都會冒出泡泡，而連接其他的水溶液，雖然也有冒泡泡的情形，但是小燈泡都不亮。鹽水會導電，其他的水溶液呢？我還想知道其他許許多多的事 … …

在一元n 次方程式中，其根與係數在在一種密切的關係。例如：若一元三次方程式 x3+px2+qx+r =0之三根αβγ則α+β+γ=-p αβ+βγ+γα=q αβγ=-r這些都是根與係數的基本關係式。由於對稱式基本定理「每一個對稱式皆可表為耀本對稱式之多項式」(證明請參閱高中數學實驗教材 自然組第六冊第 96 項）所以我們可以將根之任何對稱式表成其係數之關係。

隨著科技的發達，工業廢棄物應運而生，在地小人稠的台灣，每年就產生約6000 公噸的廢觸媒，為了讓環境免於遭受廢棄物的污染，本實驗著重於廢觸媒的再利用，探討廢觸媒作為混凝土中礦物摻料對水泥(砂)漿流動性的影響。 本實驗所採用的廢觸媒來自石油裂解廠的靜電集塵廢觸媒，主要由SiO2 及Al2O3 所組成且具有部份非結晶相和卜作嵐材料之特性，外觀為乳灰白色粉末、含水量2.8﹪，溶於水中有放熱現象，pH 值為3.85。廢觸媒對水的親和力大，添加至水泥(砂)漿中會使得漿體的流動性減小，因此必須藉由提昇強塑劑劑量才能提高工作度。 在水膠比(W/B)為0.42 時，隨著強塑劑HPC-1000 劑量的增加，水泥漿的流度明顯增加，而且適當量的廢觸媒取代水泥，能維持水泥漿一定的流度。當強塑劑HPC-1000 劑量為3.0﹪、砂/水泥＝2.75 時，隨著水灰比(W/C)的增加，水泥漿的流度也明顯增加，而同條件下，不論水膠比(W/B)0.485 或0.55 時，廢觸媒取代水泥之水泥砂漿的流度比飛灰、爐石、高嶺土好，與矽灰相當，其最佳取代水泥量為15﹪。 As technology continues to develop, a considerable amount of industrial wastes have been produced.In Taiwan, over 6,000 tons of spent catalysts were brought out yearly. If such wastes can be reused in some ways, it may be helpful to protect our environment from being polluted. This study was taken to determine the influence of spent catalysts on the flowability of mortar while the catalysts were used as mineral additives for concrete. Since the catalysts could reduce the flowability of cement pastes because of the affinity between the catalysts and water, it was necessary to have superplasticizers added to improve the fluidity of the mortar. The spent catalysts used in this study were spent electrostatic precipitator cracking catalysts, called Epcat, which were provided by petroleum refining companies. Comprising mainly silicon oxide and aluminum oxide, the off-white catalyst powder present water content of 2.8%, pH value of 3.85 and exothermic reaction with water. In this study, it was found that while the ratio of water to binder (W/B) was 0.42, the flowability of the cement pastes increased with the increasing addition of superplasticizers. Besides, the flowability of cement pastes kept steady while a proper amount of Epcat was used to replace cement.When the ratio of sand to cement (W/C) was 2.75, with 3.0% superplasticizers HPC-1000 added,the flowability of the mortars markedly increased while the W/C increased, and the replacement with spent catalysts made the mortars show similar flowability as silica fume but better flowability than fly ash, slag and kaolinite, no matter the W/B value of the cement pastes was 0.485 or 0.55. In fact, the best Epcat replacement for cement was 15%.

本研究主要在探討如何測量水的混濁度，從文獻中知道，測量混濁度的方法大多利用沙奇盤(Secchi Disk)或量筒法。這二種方法對我們來說都有不方便的地方，因此我們利用廢棄計算機上的太陽能光電池研發出一個測量溶液混濁度的工具。我們自己稱它為『光電池法』，它排除目視測量的不客觀，測出的數值我們自己稱它為 VTU(Volt Turbidity Units)，VTU 越低，混濁度越高；反之，越低。我們也探討影響溶液混濁度的因素有『濃度』、『顏色』及『溶質顆粒大小』。最後利用『光電池法』測量新店溪及淡水河的混濁度，發現新店溪下游的水最混濁，其混濁程度相當於 0.5~0.6g 的麵粉溶於 500 cc 的水中。
