利用qRT-PCR探討塑膠微粒對中華擬同型蚤生長和生殖機制的影響

隨著科技的進步,塑膠產品逐漸在全球遍布,甚至造成許多的環境汙染,其中看似消失的塑膠,其實已被分解為非肉眼可見的塑膠微粒,並且正在影響整個生態,並且在最底層的生物體內累積,透過生物放大作用不停的向生物鏈頂層增加。 探討塑膠微粒與中華擬同型蚤生長和生殖機制的影響。延伸對生殖機制、內分泌系統的影響,產生冬卵的特性,以及與體長、生長抑制、延後抱卵的關係。期望可以透過研究成果類推至生態系中的其他生物,例如魚類、鳥類和人類,進而發展成生物鏈之累積和影響。

合成二硫化鉬為基材之氣凝膠吸附環境毒性之含硫分子

由於經濟需求,人們對於農藥的使用量增加,若善後工作處理不當,易使汙染落入環境中,造成生態汙染及食安疑慮,因此本研究製作二硫化鉬奈米片作為選擇性的二維吸附材料,在過程中產生結構上的缺陷,進行化學反應吸附環境中的毒性硫化物。並使其摻混於氣凝膠中,應用於水溶液中去除常見的農藥—得恩地。 透過合成以二硫化鉬為基材的氣凝膠,在定溫定壓及pH值範圍恆定的前提下,我們分別以吸附時間、起始濃度作為操作變因,研究其奈米級二維材料與其氣凝膠之移除率、最大吸附量和恆溫吸附模式,並與活性碳比較後,發現二硫化鉬奈米片具有特異性之有效吸附,氣凝膠易於回收並可增進其吸附量之優勢,進而達到去除汙染物的目的。

鉍定藍住你⎯探討改變鉍鐵氧BiFeO3製程條件降解亞甲藍之效果

染整工業所產生之染料廢水處理一直都是個難題,傳統的處理方法皆具有其優缺點。本研究是利用壓電材料-鐵酸鉍BiFeO3 (BFO)進行亞甲藍降解,當BFO受到外力時,會出現正壓電效應並產生電場,使水溶液生成高活性的自由基,並產生氧化還原反應分解染料。我們先利用水熱法合成BFO,並且利用降解50ppm的亞甲藍的過程中找出合成之最佳溫度與水熱時間。而我們合成之最佳BFO經過一小時的降解後,可將亞甲藍濃度降解下降53%,接下來我們分別利用三種金屬離子取代Bi與Fe,我們發現當Ba:Bi=3:7與Ti:Fe=2:8時,可將降解率提高至73%與58%,我們期待此方法能為染料廢水的處理提供一個新的選擇,為環境盡一份心力。

「塑」戰「塑」決────Aspergillus屬分解塑膠能力測試

本研究選用Aspergillus tubingensis、Aspergillus oryzae、Aspergillus japonicus 三種真菌作為研究對象,將實驗分為兩個部分,一為三種真菌是否能降解PU、PE、PLA三種塑膠,結果發現Aspergillus tubingensis在黑暗中皆能降解塑膠而效果為PU、PE>PLA,Aspergillus oryzae 與Aspergillus japonicus則有降解PU與PLA之能力。二為探討Aspergillus tubingensis在不同色光及不同pH值下降解塑膠的效果,結果發現Aspergillus tubingensis 在相同色光不同瓦數情況下,降解PLA的能力為3W>1W,降解PU則是1W>3W;相同瓦數的情況,降解PU能力為白光>紅光>藍光,降解PLA能力為紅光>白光>藍光;在pH=4及pH=9環境中皆無明顯降解塑膠之能力。

以β相氫氧化鐵奈米顆粒修飾三氧化鎢奈米片以應用於高效能光電化學水分解產氫

隨著人們對綠色能源的日益重視,具有乾淨、無污染優勢的氫能源被寄予厚望。光電化學水分解被認為是一種新穎且有前景的產氫策略。然而,光電化學水分解受到載流子分離效率低、載流子界面傳輸速度慢和可見光吸收差等因素限制。FeOOH曾被報導能有效進行表面改質,並提升活性位點的手段,尤其β-FeOOH具更優秀的電化學表現,且具豐富的氧空缺,其可以輔助電洞轉移並與Fe2+結合[1],因此本研究使用β-FeOOH奈米粒子修飾WO3奈米板的表面,且因為它具有較低的能隙,可有效提高其在可見光區域的光吸收。光電流密度在1.23 V vs. RHE(可逆氫電極) 時可顯著提高至1.41 mA /cm2,比純WO3奈米板高約2.3倍。特別是FeOOH @WO3奈米板的雙電層電容值更是提升至472 μF/cm2,並且在太陽光的吸收比純WO3奈米板都更有優勢。未來,我們將結合儲氫技術開發成套供能裝置,不斷提高太陽能製氫系統的效率。

Nanoparticles and Aqueous Amine-Based Formulation to Develop CO2 Foam for Sequestration and Oil Recovery

Carbon dioxide (CO2) is an important greenhouse gas that helps trap heat in our atmosphere; without it, our planet would be inhospitably cold [1]. It is the fourth most abundant gas in the Earth's atmosphere. It is a byproduct of normal cell function when breathed out of the body, and produced when fossil fuels and organic wood compounds are burned [2]. However, an increase in CO2 concentration in the atmosphere can contribute to climate change and ocean acidification, and exposure to high levels of CO2 can produce a variety of health effects [3]. Human progress and economic innovation have led to increased emissions, causing climate change and affecting all living creatures. Current levels are 36.8 Gt CO2 in 2023 and are expected to reach 54-56 Gt CO2 by 2030 [4]. Figure 1 displays the current atmospheric CO2 measurements at Mauna Loa Observatory without seasonal variations [5].

以高選擇性膦酸錯合物作為螢光感測器檢測水樣重金屬離子(Zn2+和Cd2+)

本研究以三膦酸酯配體、2-(2-吡啶)-苯并咪唑和 Cd(ClO4)2、CuCl2,合成[Cu2 (H6tpmm)2(Hpybim)2]⋅H2O和[Cd2 (H6tpmm)2(Hpybim)2(H2O)4]·2H2O兩種膦酸錯合物,分別稱之為Cu-Complex和Cd-Complex,錯合物與重金屬結合後會產生螢光,藉此可量測是否水樣中含有重金屬離子。實驗結果發現,Cu-Complex會和Cd2+和Zn2+離子結合並產生明顯的螢光反應,Cd-Complex則會和Zn2+離子結合產生明顯的螢光反應,且能偵測到極微量的水中重金屬Zn2+達0.0086ppm,遠低於環保署的排放標準5ppm。經由測定工廠的流放廢水能確定將此錯合物運用在現實生活中的可行性。此外,我們合成的Cu/Cd-Complex提供一另類化合物檢驗水樣重金屬的方法,有別於用傳統昂貴精密儀器檢驗法,有運用於檢測生活中水質特定重金屬的潛力。

Autonomous Ecosystem Surveillance Robot

Our project, the Autonomous Ecosystem Surveillance Robot, aims at closing the aquatic gap in biosecurity measures by including several functions, such as water quality monitoring, aquatic species monitoring, and seabed topology surveillance. Several instances have shown the need for such a system, as demonstrated below. The United States Corps of Engineers completed an electrich fish barrier in the Chicago Sanitary and Ship Canal in 2002, in order to prevent the invasive Asian carp from moving into the Great Lakes. The introduction of the Asian carp into the Great Lakes would be an ecological disaster, as the Great Lakes provide an ideal habitat for the carp to proliferate, choking out native fish species that exist there. This would result in a major loss for the fishing industry in the area. One of the Great Lakes, Lake Erie, suffers annual algae blooms threats, which affect up to 12 million people in the Great Lakes region of the United States and Canada. These algae blooms are caused by runoff pollution, which occurs when rainfall washes fertilizer and manure from farmland into Lake Erie, fueling algae that can make water toxic to humans and animals alike. In addition, there are many existing customs regulations around the world that are set in place to ensure biosecurity of national ecosystems, such as in Taiwan, where it is illegal to bring pork from abroad. Despite this, there still exists a very large gap in biosecurity measures; that of the aquatic nature. Through these three functions, we have the ability to protect local aquatic biodiversity via the ability to detect invasive species, therefore allowing authorities to properly deal with them. This allows less harmful measures to be taken against them, thereby limiting collateral damage to endangered native species. Coupled with the ability to map bodies of water, the Autonomous Ecosystem Surveillance Robot is an extremely potent tool to preserve aquatic biodiversity and to ensure biosecurity of local waters.

Automatic Solar Panel Sprinkler Irrigation System

As the global demand for sustainable agriculture practices and renewable energy sources continues to rise, the integration of solar power technology with irrigation systems has gained significant attention. This abstract presents an overview of an innovative solution known as the "Automatic Solar Panel Sprinkler Irrigation System," which combines solar panels and smart irrigation technology to efficiently manage water resources in agricultural settings. The proposed system leverages solar panels to generate electricity and simultaneously operate an automated sprinkler irrigation system. Solar panels are strategically positioned in proximity to crop fields, utilizing photovoltaic cells to convert solar energy into electrical power. This energy is then harnessed to power the irrigation system, providing a sustainable and eco-friendly method for crop hydration. In Solar Power Generation the system consists of photovoltaic panels designed to capture solar energy during daylight. This renewable energy source is converted into electrical power, which is stored in batteries for subsequent use. Automated Sprinkler Irrigation is an advanced control system manages the irrigation process, ensuring efficient water distribution based on crop requirements. Soil moisture sensors and weather data are integrated to optimize irrigation scheduling. In Remote Monitoring and Control, farmers can remotely monitor and control the irrigation system through a user friendly interface, accessible via smartphones or computers. This feature enables real-time adjustments and ensures that water resources are utilized optimally. In Water Conservation the system is designed to minimize water wastage by delivering precise and targeted irrigation, reducing over-watering and the associated environmental impact. In Cost Savings the harnessing solar power, this system reduces electricity expenses, making it an economically viable solution for farmers, particularly in regions with ample sunlight. Using a tracker with an automatic solar panel sprinkler irrigation system can be a smart and efficient way to optimize the system's performance. And the most important thing is that in my prototype it is under the panel and will track the location of the Sun and with that it will lead to the Automatic movement of the panel from east to west and when the evening starts it will go back to its position.
