化学研究
Harvey Mudd chemistry faculty believe that research of project work on a significant chemical problem is a particularly valuable educational experience. 高级研究(化学151-152)是化学学位的顶点经验. 学生与教师一起参与研究, some starting in their first year; all chemistry majors pursue research and write a senior thesis. 大约15到25名学生在暑期在系里做研究项目, 我校师生合作发表了多篇论文.
Financial support for chemistry research comes from the John Stauffer Charitable Trust, 玫瑰山基金会, 国家科学基金会, 美国国家卫生研究院和默克公司/美国科学促进会.
夏季研究2024
All Harvey Mudd College undergraduates are invited to participate in the Summer 研究 program of 2024. Applications are especially encouraged from chemistry and joint chemistry/biology majors and underclassmen strongly considering a major in either discipline. Our summer program runs for 10 weeks (tentatively May 20–July 26) under the direction of Professor David Vosburg. 学生将进行研究, 学习化学专业知识, 磨练他们的演讲技巧. 如有任何问题,请联络: chemistry@onesourcehomeinspection.com.

布鲁克教授-高分子化学和化学生物学
聚合物的形状依赖性降解性
Many plastics are used for only a few minutes before being discarded to sit in landfills for decades. 迫切需要创造性的解决方案来回收废旧材料. We are developing new strategies to degrade plastics by leveraging novel elements of material design. Student researchers on this project will gain experience in polymer synthesis and characterization, 核磁共振光谱学, 排色色谱法, 和超声破碎法.
了解益生菌的生长
The human body is composed of trillions of microbes that are key regulators of our health. This dynamic and diverse population comprises both beneficial commensal organisms and harmful opportunistic pathogens. We are developing a new approach to carefully manage this balance through the identification and design of prebiotics that selectively favors the growth of beneficial bacteria over pathogens. 该项目的学生研究人员将获得BSL-1细菌培养的经验, 以及化学生物学和微生物学的技术.
希利教授-杂化材料化学
用于下一代储能的混合材料
为了应对气候变化,我们需要更清洁、更有效的方式来储存和使用能源. Many of the proposed “next generation” energy devices (things like fuel cells or advanced battery technologies) require conductive solid components known as Solid State Electrolytes or SSEs. 不幸的是,目前SSE材料的选择都有缺点. 无机材料往往具有高导电性,但难以处理. Organic materials (usually polymers) tend to be easy to process, but are relatively poor conductors.
在混合材料化学(HMC)实验室, we’re interested in generating “hybrid” materials with both organic and inorganic components, 它将有希望结合有机和无机材料的优点. 我们对晶体间的相变特别感兴趣, 这些杂化材料的液态和非晶态, 以及这些相变对材料性能的影响. 希望, we’ll collaborate with some international colleagues who’ll do some additional characterization on your materials.

Professor Hernandez-Castillo—Working Towards the Understanding of Structural Changes of Anticonvulsants
This summer the Mol-Spec lab will focus its attention on testing our REMPI-TOF spectrometer. 用它, we hope to gain insight to the structural changes that occur in a series of phenyl-containing succinimides.
Succinimide based anticonvulsants are used to mitigate the effects of absence seizures. The key to understanding a molecule’s behavior is to first understand its structure and then how it interacts with its immediate surroundings. The role that is played by the phenyl ring in the mechanism of action of certain anticonvulsants is still under active investigation. 为了更直接地探测这个苯环,我们将使用我们新获得的, tunable pulsed laser system to record vibronically resolved electronic spectra of the phenylsuccinimides using our Resonance-enhanced Multiphoton Ionization – Time of-flight (REMPI-TOF) mass spectrometer. 今年夏天我们要研究的三种分子是苯苏酰亚胺, 得琥珀酰亚胺, 4-氨基邻苯二胺.
该项目的学生研究人员将获得真空室的专业知识, 飞行时间质谱仪, 电子光谱, 电子结构计算, 先进的激光, 量子力学. They will also use experimental tools that grew out of other fields to solve current chemical problems.

Professor 范Heuvelen—Development of Bio-Inspired, Environmentally Friendly Catalysts
开发生物催化剂
Metalloenzymes found in biological systems catalyze a remarkable range of reactions with impressive efficiency and selectivity, 这些反应是在地球上丰富的材料的良好条件下进行的. 范Heuvelen实验室从大自然中汲取灵感,开发新的, 重要反应的环境友好型催化剂.
We are currently studying the dechlorination of carcinogenic pollutants perchloroethylene and trichloroethylene. Metalloenzymes containing cobalt or nickel have been shown to remediate these pollutants. We synthesize small molecular mimics of metalloenzyme active sites and evaluate their reactivity. Insights into the fundamental chemistry that governs these reactions will be used to improve our catalyst design. 我们也用计算方法研究我们的化合物.
对这项工作感兴趣的学生,鼓励与教授联系. 范赫维伦 vanheuvelen@g.onesourcehomeinspection.com 谈谈这个夏天在实验室的机会.
