How much carbon is absorbed by soil and particular land uses
挪亚雷利
劳伦磨刀石
Along with 劳伦磨刀石, I will be conducting research regarding the following inquiry: How much carbon is absorbed by soil and particular land uses? 研究 被分成了两个部分. 首先，我们会去各个地方收集 不同的土壤样品. We will then take these soil samples and analyze them by finding their bulk density analyses using the ped/geometric approach and texture analysis 使用浮标法. 然后将使用圆柱体计算该信息 排水量. After this, using 1- and 2-dimensional NMR, FTIR, and UV/vis (including complexation with metals) for our spectroscopic analysis and using a variety of solvents and extraction conditions we are going to try and find correlations between found characteristics and common classes of organic materials in soils, as well as correlations between the soil characteristics and carbon sequestration potential in 长期来看. Ultimately, we'd like to find a simple spectroscopic methodology 这可以适应野外便携式技术.

河流叙事
尼古拉斯Hegenauer
A sensor array, built around the TI CC1350 and containing a variety of sensors for species of environmental interest, will be constructed and located in Wege Pond. 的 first type of sensor will be an ion-sensitive electrode which will be glued to capillaries. 这些 polymers hold a placeholder molecule and when the molecule of interest binds the concentration of the measured ion, changes cell potential. 自动采样 device will be constructed to collect samples at specified time intervals. 这些 samples will be studied later by laboratory methods such as atomic absorption spectroscopy 或者色谱法. Finally, a ligand and metal complex sensor may be developed, when the target molecule binds to the ligand, the complex changes color triggering 传感器.

Growth of Mixed-Metal Oxide Thin Films and their Optical, Electrical, and
光化学性质
布莱斯普拉特
A growth chamber will be constructed to allow for the creation of mixed-metal oxide films consisting of Titanium (IV) and another transition metal. 从这些电影中， the optical, electrical and photochemical effects will be measured. 的光化学 effects of these films should have a wider absorption spectra compared to films made with only Titanium (IV) and therefore provide better absorption of energy from light. 的 growth chamber will be designed to allow for trials at varying temperatures to measure the structural changes at these different temperatures. 金属用于 synthesis will be created in the laboratory while the chamber is being constructed.

Synthesis and 描述的 Ionic Liquid Crystal Compounds
亚伦Batke
的rmotropic liquid crystals are compounds with an intermediate phase between crystalline 固体和各向同性液体. 它们可以通过改变被诱导成相变 它们的温度. One category of liquid crystals are ionic compounds composed of metal halide ions that are attached to alkylammonium cations with positively-charged 氮原子连接在疏水的碳氢化合物尾部. 对这些化合物的兴趣 已经存在了45年了吗. 研究涉及烷基链长度的范围 和不同的过渡金属卤化物. 然而，镧系金属还没有 充分探索. We will synthesize one or more ionic liquid crystal compounds containing alkylammonium cations with samarium chloride anions. 描述的 the resulting compounds may include elemental analysis, differential scanning calorimetry, melting point analysis via Mel Temp apparatus, polarizing optical microscopy, and 傅里叶变换红外光谱. 我们希望新化合物能表现出热致性 液晶相. 的 presence of the lanthanide element may also cause fluorescence. This work will contribute to a previously unexplored region of chemistry.

Scope of an Under Air Direct Arylation Reaction with Respect to Aryl Halides
加贝Brandonisio
Direct Arylation is a type of reaction used by organic chemists to cleave C-H bonds on aromatic compounds and form C-C bonds with other aromatic compounds. 通常 these reactions are done under an inert atmosphere, but previous Aquinas students that have studied this reaction using air and obtained yields just as good. 前面的 students have found optimal conditions for the reaction to take place. 建立了 of their research, our goal is to explore the scope of the reaction with respect to 芳基卤化物.

OXA-207的动力学研究
艾弗里便宜
We are studying the enzyme kinetics of OXA-207, a Class D beta-lactamase. Beta-lactamases catalyze the hydrolysis of beta-lactam antibiotics, a broad class of widely used antibiotics. By doing so, the beta-lactamase can confer antibiotic resistance to the microbe that 表达它.
OXA-207 differs from its parent enzyme by just one amino acid. 我们正在测量
动力学使用一堆不同的-内酰胺底物.

OXA-207的动力学研究
雅各布·麦金德
Beta-lactamases are enzymes that catalyze the hydrolysis of beta-lactam antibiotics (e.g. penicillin) and confer antibiotic resistance to the bacteria that produce them. We are studying an example of a Class D beta-lactamase, OXA-207, which differs from its parent enzyme by only one amino acid, but exhibits distinctly different substrate 首选项. We hope to fully characterize the substrate profile of OXA-207 and possibly 调查造成差异的结构性原因.

Structural Effects of Buchwald Ligands in Direct Arylation Reactions
约翰迈克菲
Buchwald ligands are a common choice for direct arylation reactions because of their 电子密度差. 我将研究这些结构的影响 ligands in direct arylation in order to better understand which ligand should be used. Direct arylation could promote advances in the pharmaceutical and solar industries.
