My Career In Energy Technology And Surface Chemistry

To the best of authors knowledge, there are no reports on electrochemical evaluation of spinel structured MnCo2O4 nanorods. In this study for the first time, the hydrothermal method has been adopted for the preparation of spinel structured MnCo2O4 nanorods. The structural, morphological and electrochemical properties of the one dimensional MnCo2O4 nanorods have been systematically studied. The electrochemical properties of the MnCo2O4 reveal that this may be a potential electrode material for supercapacitor

Chemical Technicians work in labs and factories and are responsible for monitoring chemical processes and testing different chemical products. They do different tasks, such as analyzing data, preparing reports, and presenting their conclusions. They do lab work and perform complicated analyses. Some technicians clean and replace filters. Chemical technicians also set up apparatus for chemical reactions.

Going to the NCSU Engineering Career Fair was both an intimidating and exciting experience. As a freshman with a Chemical Engineering Intent looking at companies, I was very intimidated yet intrigued by the mass amount of companies represented at the career fair. Investigating the companies prior to the career fair, I narrowed my list down to three chemical engineering companies: EcoLab, Merck, and GSK.

Copper acetate monohydrate (Cu(CH3COO)2.H2O, SRL, AR Grade), Iron(III) nitrate nonahydrate (Fe(NO3)3 9H2O, Thomas Baker, AR grade), cadmium dihydrate (Cd(CH3COO)2.2H2O), tin chloride dihydrate (SnCl2.2H2O, Merck, GR grade), and thiourea (CS(NH)2, SD Fine, AR grade), and ethanol (Merck, AR grade) were the precursors used for synthesis of CFTS and CCdTS nanoparticles. The electrolyte is composed of the following chemicals: 0.1M lithium iodide (LiI, Anhydrous, Merck), 0.05M Iodine ((I2, Thomas Baker, LR), 0.5M 4-tert-Butylpyridine (TBP, Sigma-Aldrich, 96%) and 0.6 M 1-Methyl- 3-propylimidazolim iodide (PMII, Sigma-Aldrich, 98%) and acetonitrile. Fluorine-doped tin oxide (FTO) substrates (TEC 8, sheet resistance 8 Pilkington), TiO2 powder (P 25,

I am teaching this Macaulay Honors College course — this content will evolve a bit organically, and I would greatly appreciate your suggestions/comments/corrections — this CCNY course is only for Macaulay undergrads, and I think that they would be very inspired if they could get a chance to hear new concepts and interdisciplinary (nanoscience & biophysical chemistry) ideas from you.

My desire is to continue a research career as an experimental physical chemist. I am grateful that I have found my passion that I found early in life and have been supported by my family and society. My educational experiences in Korea and the U.S. have demonstrated to me that the social support and infrastructure are immensely important for individuals to live out their passion, especially in the STEM field. As a female physical chemist who pursues an academic research, I will strive to contribute to making an inclusive and supportive scientific community.

“Capturing the fundamental growth and evolution of these particles in motion will help us immensely in our work with synthetic materials and their interactions with biological systems,” says Gianneschi, who serves as the Jacob and Rosaline Cohn Professor of Chemistry in the Weinberg College of Arts and Sciences. Neither he nor Parent has likely underestimated the significance of this study in light of the prospective influence it may very well have on future research. In fact, new insightful studies can now be published simply based on recordings of feats already accomplished with nanoparticles because the value will be not in the feat itself but, rather, in the well-defined recording thereof. Much like the value in Gianneschi’s study, it would be in learning more about the dynamics and behavioral parameters of nanoparticles.

The conversion of the sunlight directly into electricity by using the electronic properties of various suitable materials appears to be an attractive energy conversion process and more or less an ideal alternative to available conventional energy sources. The solar cell technology has developed enormously over the last four decades, initially for being used to provide electrical power for spacecrafts and also more recently for various terrestrial applications. The main reason for this technological development lies in the realization that traditional fossil energy resources like coal, oil and gas are not just rapidly depleting, but they also contribute to unpredictable and probably irreversible climate changes in the approaching future through the extreme high emission levels of greenhouse gases (e.g. CO2, CO, SO2 and P2O5) and also due to acidification. The photo voltaic source of energy that is solar irradiation, has the major advantage of being widely distributed over the world. The solar irradiation falling on the earth’s surface is not a limiting factor and also supersedes our needs by far. Photovoltaic industry has leapfrogged the barriers over the last three decades from merely being a conceptual industry to a full-fledged commercial industry. Recent major investments and the on hand manufacturing facilities are only mainly for silicon based technologies, with more than 93% market share, mainly due to its maturity, growth and huge

In light of these shortcomings, there has been an upsurge in eco-friendly materials and devices, all in an effort to recover and save the environment. Nanotechnology, which deals with matter on an atomic level, has played a significant role in this movement.

Chemical engineering has been my passion since high school. Having dad who is an engineer clearly backs up my interest in the field of engineering although my dad pursued a different field which is mechanical engineering. I always admired to be an engineer having my dad as role model. I did not know what to pursue till I got to high school when I was able to delineate my strengths. From an exemplary performance I could tell chemical engineering is the path I need to pursue. Chemical engineering has been my passion since high school.

Recently, the method of electrospinning by heat treatment has received significant attention owing to its simplicity, high efficiency, and versatility for the preparation of diverse one-dimensional structures. For example, Zhao’s group fabricated the composite film electrode of MnO/Carbon through incorporating MnO2 nanowires from hydrothermal into polymer solution by a facile electrospinning technique. The MC-800 membrane exhibited a high reversible capacity of 987.3 mAh g −1, after 150 cycles at 0.1 A g−1, a good rate capability (406.1 mAh g−1 at 3 A g−1), and an excellent cycling performance (655 mAh g−1 over 280 cycles at 0.5 A g−1). Liu et al. designed a flexible membrane through incorporating Mn3O4 nanoparticles, encapsulated in

TiO2 nanowires could be a hope for the growing environmental challenges with its photocatalytic property and gas sensitivity [6]. It may also a resolution to the energy crisis with its photovoltaic and water splitting properties [7].

Large solar plants occupy a vast area of land and threaten wildlife because one square kilometer is needed to produce 40 megawatts of energy from solar power.4 British scientists are attempting to improve the effectiveness of photovoltaic cells by utilizing “copper indium diselenide and cadmium telluride to find an affordable and more sustainable way to make solar panels to convert light energy into electricity.”5
