我們想從提升實驗室中長晶的效率,來製造漂亮的寶石。因此先從硫酸銅的長晶開始,將晶種移到用Arduino電路板裝設的半自動長晶儀器中,用程式去控制攪拌速度及溫度。經過多次的測試,了解長晶的各種參數,最後總結出最佳的長晶策略是:把長晶的溶液攪拌速度調低,加上每1.5小時的人工上下攪拌,從準安定區的高溫邊界57.5 ℃,每1~2小時以0.5℃階梯式的降溫方式、降到比不安定的邊界高0.5 ℃,以不斷創造最高的過飽和濃度。經過6小時,每小時長晶量越來越多,所以長晶的最後階段、每次降溫0.5℃是很關鍵的!接著我們將結晶系統改成氣泡式全自動的方式,使濃度可以自動上下左右混合均勻,因而提高了長晶量,使探索各種晶體的成長機制更有效率!

高壓「碳」究、「碳」為觀止─以牡蠣殼加壓溶解進行化學固碳之可行性研究
本研究旨在探討廢棄牡蠣殼(主成分CaCO3)在模擬加壓環境下與二氧化碳及水反應,進行化學固碳(CaCO3+H2O+CO2⇌Ca(HCO3)2)的可行性,並連結深海高壓環境有助於穩定碳酸氫鈣的概念。研究小組設計實驗裝置(包含固碳反應艙、二氧化碳集氣筒、未反應二氧化碳收集筒)模擬壓力,探討反應時間、牡蠣殼粉用量、初始壓力、水溶液種類、混合方式及溫度等變因,並以二氧化碳氣體體積減少量作為觀察指標。 研究結果顯示,牡蠣殼粉確實能與CO2進行化學反應,反應量顯著高於單純的CO2物理溶解。進一步實驗發現,提高壓力、降低溫度、加強混合(每5分鐘攪拌)及延長反應時間均能提升CO2總反應量。然而,在本實驗條件與時間範圍內(最長60分鐘),3克牡蠣殼粉的效果優於6克及9克,且純水效果優於海水。本研究驗證了牡蠣殼加壓固碳的可行性,並模擬深海環境來找出反應效率的關鍵因素。研究小組進一步發想深海牡蠣殼固碳系統,為此廢棄物再利用及深海固碳概念提出創意規劃。

Fabrication of Tandem Dye-Sensitized Solar Cells to Enhance Photovoltaic Performance
Energy has had an enormous impact on the development of technology and is a main factor in humans’ advancement towards an evolved society. Nevertheless, nonrenewable energy resources – which are the most effective in everyday application - have led to changes in the climate, environment, human health, and the world in general [1], which has encouraged researchers to switch to the use of renewable energy sources. Solar Cells are one of the most effective resources that rely on renewable energy. They come in a variety of types, operation methods, and efficiency as shown in Figure 1, including Dye-Sensitized Solar Cells (DSSC), which, inspired by photosynthesis in plants, uses photo-sensitive dye to capture sunlight and generate electricity. DSSCs were proved to have generated a great deal of interest and are one of the most promising solar cells among third-generation PV technologies, due to their low cost, simple preparation, good performance, and environmental friendliness compared to conventional photovoltaic devices [3]. However, their efficiency is quite insufficient for everyday use. Previous studies proved that Tandem DSSCs – which are two dye-sensitized cells stacked on top of each other – are able to enhance cell performance. The light absorption range of a tandem cell is increased because the bottom cell behind the top one absorbs and uses the incident light that was not absorbed by it [4]. It operates as shown in Figure 2, where the light photons excite the electrons of the dye molecules. The electrons are then transported to the FTO (conductive glass) by the semiconductor, which is used in the figure as TiO2 nanoparticles. The electrons pass through the circuit to perform the work, then move to the counter electrode (shown as Platinum). They are then transported by the electrolyte (I-/I3-) back to the dye molecules, and the process is repeated.

本作品主要探討在網格上進行全等切割的方法數,並分析其擁有性質,於研究過程中發現當方形網格邊長達到6時,切割路徑會產生「回繞」的複雜情形。因此本次研究由「回繞數」為0的切割路徑討論起,並給予網格分層的定義,依序探討正方形網格、長方形網格、三角形網格及六邊形網格切割成不同等分時的方法數,而後我們再進一步討論正方形網格「回繞數」為1時的全等切割,並利用遞迴式得出切割方法數。 此外在研究中,我們透過排列組合計算出長方形網格在不受回繞限制下的一般式,並嘗試討論立體網格的情形,在增加對「懸空數」的限制下,經計算得出了有趣的結果。

Design and Simulation of a Honeycomb Sandwich Panel as a Heat-resistant and Durable Construction Material
One of the main factors that contribute to fire incidents and the excessive heat people feel during a heat wave is the building materials used, and one such material that possesses durable and heat-resistant properties is sandwich panels. A possible structure that can be used to model sandwich panels is honeycomb structures; however, further research has yet to be conducted on its applications as a heat-resistant urban construction material. This study aims to design a three-dimensional model of a honeycomb sandwich panel and simulate its performance under different thermal and structural stressors. A 3D model of the honeycomb sandwich panel was generated using Autodesk Fusion 360. Then, multiple versions of the panel were generated with varying heat-resistant core materials—namely, aluminum, nickel, nickel-copper alloy 400, and copper—along with polystyrene as the core material for the control model. The following properties of every panel were assessed using finite element analysis (FEA): static deformation, stress distribution, strain distribution, total heat flux, and thermal gradient. Results showed that when subjected to varying structural loads (2 kN, 5 kN, 7 kN), the nickel-core panel demonstrated the best results in terms of static deformation and strain distribution due to its relatively lower deformation and elongation values, respectively. Meanwhile, under the same structural loads, the aluminum-core panel performed better than other core materials in terms of stress distribution due to it having the relatively highest difference between its simulated von Mises stress and its yield strength. The honeycomb sandwich panels have also shown to possess heat-resistivity when subjected to a thermal load of 90°C, with polystyrene being the most promising material overall in terms of heat-resistance due to its relatively lower heat flux and thermal gradient. The results from this study would contribute to future research on honeycomb sandwich panels and may be used in real-life applications.

KidneyLifePlus+ : Retinal Imaging Analysis for Kidney Disease Risk Assessment
Chronic kidney disease (CKD) represents a significant public health challenge, often referred to as a “silent disease” due to its asymptomatic progression during early stages (1–2). Consequently, most diagnoses occur during advanced stages (3 and beyond), where treatment options are more complex and outcomes are less favorable. Globally, CKD affects over 850 million individuals, with 434.3 million cases in Asia alone. Despite its prevalence, early-stage awareness remains alarmingly low, with only 5% of affected individuals aware of their condition. Existing screening methods are predominantly hospital-based, expensive, and time-intensive, limiting their accessibility, particularly in resource-constrained settings. This underscores an urgent need for more accessible and efficient diagnostic tools to enable early intervention. In response to this critical problem, we developed KidneyLifePlus+, an AI-powered platform that leverages advanced machine learning models, including U-net, ResNet-50, and YOLO v8, to analyze retinal images for early CKD detection. These models are integrated to ensure high screening accuracy by identifying subtle biomarkers indicative of CKD progression. Complementing the software, we designed proprietary hardware capable of capturing high-resolution retinal images, delivering performance comparable to hospital-grade equipment. By ensuring affordability and ease of use, the system extends screening capabilities beyond clinical environments, making it suitable for deployment in community healthcare settings. KidneyLifePlus+ addresses key limitations of traditional methods by offering a rapid, cost-effective, and highly accurate diagnostic solution. The platform’s potential to enhance early detection rates could significantly improve clinical outcomes and quality of life for CKD patients. Furthermore, this innovation contributes to global efforts to reduce the burden of CKD by promoting equitable access to diagnostic services, particularly in underserved regions.
