奈米防蝕專家-微乳液法製備聚苯胺奈米粒子及其在防蝕應用研究
導電高分子在各面之應用非常廣泛,其中聚苯胺因價格便宜,製作簡便,使\r 其應用潛力更為突出。聚苯胺在鐵系及非鐵系金屬之防蝕能力已被證實,但由於\r 聚苯胺與金屬之附著力不良使其應用受到限制。奈米粒子所具有的表面效應、小\r 尺寸效應及宏觀量子隧道效應,使得奈米微粒材料之應用蓬勃發展。但在高分子\r 奈米微粒之製備仍屬有限。本文以微乳液法製備聚苯胺奈米粒子,以提高聚苯胺\r 與金屬間之附著力,使其防蝕能力充分發揮。國外雖已有廠家製作聚苯胺防蝕塗\r 料,但屬於商業機密無從得知其製備方法。本文所研發的微乳液法則是國內首\r 創!\r The development and application of the conducting polymer polyaniline is\r getting prosperous and popular. The capability of polyaniline in corrosion protection\r has been proved. But due to the adhesion of polyaniline on the metal is poor, the\r applications are restricted. By the way, the nanoparticles have the special effects such\r as the surface effect, the small size effect and the macro-quantum channeling effect\r make its applications are prosperous.\r In this paper, the authors utilized the microemulsion method to produce the\r polyaniline, to modify the adhesion of polyaniline on the metal in order to improve\r the effect of the corrosion protection of polyaniline in ferrous metal. The experimental\r results show that the nano-polyaniline has good adhesion on metal. The metal coated\r a layer of nano-polyaniline has the great ability of anticorrosion under different\r corrosion situations after weeks. The nano-polyaniline produced by the\r microemulsion method add the recipes invented by the authors has great potential to\r use in scale-up production in industry.

一般公寓其公共用電,例如樓梯電燈、電門,抽水馬達,甚至空調冷氣、電梯等公共設施之用電費用,皆裝有一公共用電表計算其費用,再由專人或者某一住戶負責向電力公司繳納費用,而後再依此費用平均分配各個住戶,此種手續電力公司和住戶均感不便,且平均費用計算易起紛爭,此種公寓公共用電自動記錄配電器,即針對這些缺點而解決上述之困擾,立即將公共設施之用電,由自動記錄器上以平均的費用或度數分別計入各個住戶之自己電表中,如此公共用電之電力便平均地由各個住戶家中透過其電表分別送至公用設施用電上。例如公寓中有六戶公共用電10度,第一次用電量取 A 家(所謂 A 家即電力公司之電力,已經由 A 家電表計數其用電費用,立即 A 家除了其家中自已用電外,同時須輪次送電至公共設施用電上)。第二次10度之公共用電量,便由自動記錄分配器上輪換至 B家,依此類推,以此六戶輪次供應公共用電。如此不但電力公司可免去收公共用電之費用,住戶也不必為收公共用電賣受困擾或均攤費用了,此種均攤用電量,經山自動配電計入各自家的用電費用。

On Course Line Management
The Online Course Management system was developed in 2012 by George Moon to address the issue of creating course books at Burnside High School in Christchurch, New Zealand. The course books are designed to inform students, staff and parents of the many courses that are available for students to choose for their next year of study. In the past, the system that the school used consisted of large amounts of paperwork and duplication. Not only did this system require a lot of effort from staff, but the course book cost the school thousands of dollars to produce, as it had to be sent off to be published into a large book that would be read by students for a week, then likely thrown out. This year the school decided to digitise the course book, so that students would look at their courses online. Earlier this year, the school believed that the new School Management System (SMS) ‘KAMAR’ would be able to handle all of the necessary information, however this was not the case. Because of this, they needed a simple solution that would collate all of the course data, and then output it as a course book. I developed my project to do this. It is a web based program that is accessible by staff on their computers which enables them to enter in all of the course and assessment data for their departments. As it is all securely stored on a central database, it reduces duplication and staff workload, as well as the added environmental bonus of less paper being used. The program also outputs data in a number of ways including as a coursebook PDF (digital document which can be uploaded or printed), an Excel spreadsheet and a webpage for easy viewing. It can be sorted or printed by different categories (such as level, faculty, department), which proved to be a very useful feature. Following some research on areas such as design principles, browser compatibility and screen resolution (computer screen size), the program was designed to make best use of this this information. For example, most of the computers that staff would access the website on were of a similar size screen, so I made sure that my website worked well for them. I also used my research on design principles to try and create a simple, clean interface that users with limited computer skills would easily be able to navigate around. The outcome was real, as it was used by the school to generate their coursebook this year. Following a 95% student completion rate of course selection many months earlier than previous years, the system (although it had some issues) was pronounced a success, and the school is looking to use it in the years to come. There are a number of steps I am looking to take in the future with this program including the potential sale to other schools, so they can take advantage of the features it has to offer.

猜不透我的心──探討影響颱風路徑的原因,及不同颱風路徑造成的災害
本報告主要研究不同變因對西太平洋颱風移動路徑之影響,方法為使用旋轉圓錐盤來模擬高壓風場,以BB 彈射入盤內時,BB 彈的下滑力和離心力平衡後,其移動的路徑,模擬颱風進入副熱帶高壓後的路徑變化。實驗結果發現,模擬高壓越強,模擬颱風越不易被快速拋出,且較強模擬高壓橫移時,模擬颱風的路徑也隨之偏轉。對照實際情況,發現高壓越強,颱風較不易被拋出,而順著高壓西側北上,有些更因高壓移動,路徑隨之偏移而接近台灣。實驗發現颱風不會被高壓直接向外推出,主因是摩擦力較小時,氣壓梯度力和科氏力平衡,形成幾乎平行等壓線的駛流風場帶動颱風移動。另外,侵台颱風路徑不是造成全面降雨的主因,明顯外圍環流及颱風眼對全面降雨的效果更強。

螞蟻也討厭塞車?~探討螞蟻覓食的交通量分佈情形
我們在2004 年7 月號的牛頓雜誌裡,偶然看到螞蟻會分配牠們的交通量這個訊息,但卻沒有多加說明,於是我們決定深入研究。我們設計了較簡單但不影響實驗結果的裝置,在公園蟻窩旁及室內各選定一個放置位置,並確認三種不同種類的螞蟻後便開始進行觀察。我們先選擇了三個地點來觀察螞蟻的生態,再著手設計了適當的實驗,開始進行研究。實驗內容包括:探討吸管(通道)顏色、粗細、易達性對螞蟻覓食交通量分布的影響。持續兩個月的研究,每天定時到三個地方統計及記錄,發現螞蟻會大略遵循著一定的規則分配交通量,例如在一條通道過於擁擠時,螞蟻會大略平均分布在兩條通道中;另一方面,螞蟻會較集中於易達的路徑等。而我們也發現此次的實驗設計,很適合當「捕蟻器」來使用,這可再深入研究。

Is the fruit safe?-吊白塊的簡易自製試劑
吊白塊是一種在現切水果中常見的食品添加物,它可使剛切的水果不易被氧化,並同時具有漂白的效果,但此種添加物會對人體造成許多疾病。本研究針對吊白塊作嘗試性的初級檢驗,選用一般常見的氧化劑和染料,自行研發簡易的檢驗方法,且進一步製作安定性佳且攜帶方便的試紙。本實驗結果發現,由衛生局提供的「藍吊試劑」本身不甚穩定,且顏色變化不明顯;在自製檢驗試劑方面,效果最佳的是過錳酸鉀,濃度可測至0.0005M,且反應相當快速,唯試液容易與水果表面的Fe(II)離子反應;孔雀綠和晶紅酸等染料效果亦佳,且變色相當明顯,但反應時間較長。Rongalit is a bleaching agent commonly used as a food additive. It can prevent fresh fruits to be oxidized (without color-changed), especially when they were cut for sale. However, as for this additive, it is not good on health and is necessary to be detected. The test-paper currently used, the so-called “blue-test paper”, can be obtained from the Department of Health (Taipei). However, its stability is poor; the color change is not clear when it reacts with Rongalit. For this reason, I developed simple methods for detecting Rongalit by using various oxidizers and dyes. A test-paper, with better stability and easily for carry, was successfully developed. The findings show that the use of KMnO4 on the homemade test-paper provides the best result. The reaction time is short and the limit of detection can be improved to 5 × 10-4 M. The color changes were also clear when malachite green and fuchsin acid were used, but the reaction times were longer.

本研究首先探討台灣各地的日照時數與世界重要都市的比較,發現台灣南部日照時數皆超過2000 小時,適合發展太陽能。接著,?了增加陽光的能量密度而加設弗瑞奈透鏡,雖然能順利的使照度放大三百餘倍,但歲日照角度的影響甚鉅,?了克服角度的問題,我們決定開發自製的追蹤器來改善角度的問題。太陽能板需要改變仰角跟傾角(雙軸調整),由光感應器判斷及自動控制程式,判斷隨時辰與季節變化的太陽角度。當搭配奈米塗料、弗瑞奈透鏡與追蹤器,總輸出功率可增加約50%。太陽電池表面玻璃會阻擋藍紫光的吸收,但本研究在太陽能板上塗佈奈米塗料,發現能增加短波長的吸收;經實驗後奈米等級表面具有自潔效應,可防止灰塵雨滴的堆積影響光線吸收,具有開發價值。This project first compares Taiwanese locations with other places in the world on average daylight times. It was discovered that southern Taiwan has the longest average daylight time all over 2000 hour sand therefore most ripe for solar power development. To increase the energy density of solar Fresnel lenses were incorporated. Although this has the advantage of magnifying illumination by three hundred percent, the alignment angle for the solar panel will have a significant impact on performance. We then designed and built a automated tracking device with illumination sensors to control the elevation and inclination of the solar panel which adjusts the angle according to environmental conditions such as time of day and season. When solar cell collocate Nano coating, Fresnel lens, tracking device, its power can promote almost150%. The glasses on the solar cell will interfere solar cell absorbing blue and purple light, but we lay on a Nano coating and we find Nano coating can improve solar cell to absorb short wave; and surface o Nano have lotus effect, it can prevent dust and rain effecting solar cell absorb lights, and it is worth developing .

是常見的現象,會對生活造成不便的影響。所以本研究的主題是:探討檯燈造成反射眩光的種種現象,並研究防眩光的原理,最後再試著DIY防眩光檯燈。為達成目的,我們首先觀察檯燈上下、左右位置變化時,眩光大小、形狀、位置的變化。在初步瞭解眩光現象後,我們推測防眩光的原理可能與防眩光板的折射、反射程度有關,所以設計了照度、輝度、雷射光折射三個觀察實驗。根據觀察結果,我們發現防眩光板具有很高的反射效果,所以光線會在檯燈內不斷反射,最後被吸收,於是檯燈照射出的亮度與眩光程度都有所降低。最後我們用十二種常見的材料DIY防眩光板,並以六項評斷標準進行評分。結果證明,我們DIY的防眩光板一點也不輸一般的商品。
