This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. My general research is in the area of electrochemistry. One of my research interests involves the design of magnetic microparticle/catalyst electrodes for improving electrosynthetic processes. Nylon, sodium hydroxide, and chlorine gas are examples of the many chemicals that are synthesized electrochemically. However, this electrochemical synthesis (or electrosynthesis) requires large power demands due to the poor kinetics of the electrochemical processes. Magnetic electrodes are being designed to increase kinetics of magnetically susceptible electrochemical processes. Thereby, decreasing the power demand and cost of chemical production. We are studying magnetic catalysts and electrodes for use in the chlor-alkali process and nylon synthesis. My second research interest involves increasing the selectivity of polymer modified electrodes using molecularly imprinted polymers. Selectivity is one of electrochemistry's largest problems. We increase selectivity by modifying the surface of the electrode with conducting polymers that are molecularly imprinted for our analyte. The third main focus of the Minteer Group is high power density and long lifetime biofuel cells. A biofuel cell is a type of battery that can be recharged with the addition of more fuel and utilizes enzymes as biocatalysts in order to convert chemical reactions to electrical energy. Our research group has developed a powerful technique to immobilize enzymes at the electrode surface. This technique has helped to stabilize enzymes for increased periods time (months instead of days) by protecting fragile enzymes in tiny pore-like structures resulting in increased power and lifetime of the biofuel cell. In addition, with this technique a wide variety of fuels can be utilized including carbohydrates, fatty acids, and alcohols.

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 我的主要研究领域是电化学。我的研究兴趣之一涉及磁性微粒/催化剂电极的设计，以改善电合成过程。尼龙、氢氧化钠和氯气都是电化学合成的许多化学品的例子。然而，由于电化学过程的动力学差，这种电化学合成（或电合成）需要大的功率需求。磁性电极被设计为增加磁敏感电化学过程的动力学。从而降低化工生产的电力需求和成本。我们正在研究用于氯碱工艺和尼龙合成的磁性催化剂和电极。 我的第二个研究兴趣是利用分子印迹聚合物提高聚合物修饰电极的选择性。选择性是电化学最大的问题之一。我们通过用导电聚合物修饰电极表面来提高选择性，这些聚合物对我们的分析物进行分子印迹。 Minteer集团的第三个主要重点是高功率密度和长寿命生物燃料电池。生物燃料电池是一种电池，可以通过添加更多的燃料来充电，并利用酶作为生物催化剂，以将化学反应转化为电能。我们的研究小组已经开发出一种强大的技术来将酶固定在电极表面。这种技术有助于通过保护微小孔状结构中的脆弱酶来增加酶的稳定时间（数月而不是数天），从而增加生物燃料电池的功率和寿命。此外，通过这种技术，可以利用各种各样的燃料，包括碳水化合物、脂肪酸和醇。
