The ability to control optical and electrical properties of materials as a function of size and dimension has profound implications in numerous miniaturized technologies such as sensing, communication, lighting, display, optical and electrical circuits, and energy applications. This talk will unravel critical information about molecular stacks from individual molecular entities and advance to our newly uncovered possibilities to co-¬‐localize, and co-¬‐assemble two distinct molecular entities in a single stack of highly organized assemblies. Such self-¬‐assembled structures show immense potential in photonic and opto-¬‐electronic devices and are a promising approach for advancing organic electronic materials in advance applications.
Second part of this talk will focus on energy harvesting and storage. The nanocarbon structures such as carbon nanotubes, and graphene are highly attractive for use as electrodes in supercapacitors, and lithium ion batteries. The detailed workings of the recent breakthroughs in ‘in-¬‐plane’ geometry that enables an ultrathin, flexible, and solid-¬‐state graphene based supercapacitors will be described. Also, nanocomposites for achieving high performance electrolytes capable of withstanding high temperatures with large voltage windows for next generation of supercapacitors and batteries will also be described.

The Taiwaniadducts I and J, as cycloadducts of terpene quinones from taiwania cryptomerioides, will be synthesized. These two compounds are isolated from Taiwania cryptomerioides hayata, a large coniferous evergreen species common to Taiwan. They have potential in medical applications due to the breadth of their biological activities. However, low yields of these naturally extracted compounds limits further research on their biological activities and no synthetic approaches to these two compounds have been reported before. Herein, we design a synthetic route which can provide adequate quantities of target compounds for further biological studies. Moreover, the design methodology involved in this proposal may show a reasonable approach to the synthesis of this kind of cycloadducts.

“Carbon Nanomaterials: from Zero-dimensional Cages to Three-dimensional Graphene Sheets “

Dr. Yun Hang Hu,  Charles and Carroll McArthur Endowed Chair Professor
Department of Materials Science and Engineering, Michigan Technological University

February 27, 2015 – 3:00 PM – Rekhi Hall G006


Because of the bonding flexibility of carbon, carbon-based materials exhibit various structures with a large variety of physical and chemical properties. Three-dimensional carbon allotropes (graphite and diamond) have been known from the earliest history. The zero-dimensional carbon fullerenes and one-dimensional carbon nanotubes were discovered within the last 30 years. Furthermore, isolated two-dimensional graphene, which is a one-atom thick carbon layer with hexagonal ‘‘honeycomb” lattice, was experimentally obtained 10 years ago. Actually, the discovery of those nano-structured carbon materials is one of the most important developments in science and engineering. In this talk, Dr. Hu is going to discuss his research for (a) the defect structures and the endohedral complexes of C60, (b) the stability and structure of atomic carbon chains, and (c) the synthesis and application of three dimensional graphene sheets and their application for energy.

Dr. Yun Hang Hu is the inaugural Charles and Carroll McArthur Endowed Chair Professor at
Michigan Technological University. His main research interests range from nanomaterials, CO2 conversion, clean fuels, hydrogen storage materials, catalysis, quantum chemistry calculations to solar energy. He has published more than 120 peer reviewed papers in reputed journals (such as JACS, Angew. Chem. Int. Ed., and Adv. Mater.) and organized more than 20 international symposia on materials and energy. He was a program chair for the ACS Energy and Fuels Division. He is an editor for three books, an editorial board member for nine journals, a chair of the ACS Energy and Fuels Division, and a president of the Hydrogen Storage Division of the International Association of Hydrogen Energy (IAHE). He is a fellow of American Association for the Advancement of Science (AAAS) and the Royal Society of Chemistry (RSC).


Assessing the Binding Capabilities of Bromodomain-Containing Protein 9

Doctoral Student, Department of Chemistry,Michigan Technological University

Monday, March 2, 2015-9:00 am- Admin 404


Post-translational modifications of histones, such as the acetylation of lysines, play an importantrole in regulating transcription. Histone tails have a large proportion of positively-charged residues, which create electrostatic interactions with the negatively-charged DNA backbone. Lysine acetylation is thought to weaken these interactions, because it neutralizes lysine’s positively-charged side chain.

Proteins recognize the acetylated lysines using bromodomains; bromodomains are acetylated lysine “readers” and play a critical role in modulation of gene expression. Of the 46 bromodomain-containing proteins in the human proteome, 15 function as transcriptional regulators and 8 function as chromatin remodelers. Nearly all of the other bromodomain proteins influence transcription in some manner (histone acetyltransferase, transcription repressor, transcription initiation, etc.). Due to their significant influence on transcription, mutations of bromodomains are often linked with cancers.

Bromodomain-containing protein 9 (BRD9) has not yet been studied. The aim of this proposed research is to determine the specificity and affinity of BRD9 toward acetyl-lysine sites on the tails of the four core histone proteins.

A high-throughput examination of possible histone interactions with the bromodomain of BRD9 will be conducted using a modified SPOT array. The peptides demonstrating the strongest interactions with the bromodomain will be synthesized using standard Fmoc peptide synthesis. A quantitative examination of the binding affinities of these peptides to the bromodomain, the bromodomain and DUF3512 (domain of unknown function), and the full length BRD9 will be conducted using isothermal titration calorimetry. The results will be compared to determine how the surrounding amino acid sequences affect the bromodomain’s binding capabilities.

Chemistry-themed Student Research Symposium at NMU, April 11, 2015

The Upper Peninsula Section of the American Chemical Society is now soliciting abstract submissions for the Student Research Symposium, which will be held at NMU’s New Science Facility in Marquette on Saturday, April 11, 2015.

The purpose of the event is to provide a venue for students to present their research in chemistry, chemical engineering and related fields. This symposium will be an excellent opportunity for students, faculty and the community at large to learn about the interesting research being conducted in the UP. This year the initiative will see the participation of presenters from schools within the Northeast Wisconsin local section.

Poster abstracts can be submitted online. The deadline for abstract submission is March 15. There is no registration fee.

Cash awards to the best posters will be given, and every participant will receive a gift from the UP local section.

Questions should be directed to Loredana Valenzano (, UPLS 2015 Chair.

Atmospheric Aerosols at PICO Mountain Research Observatory

Dr. Lynn Mazzoleni, an assistant professor of chemistry, is currently at the top of Mt. Pico, an extinct volcano in the Azores. She’s working on understanding aerosols’ chemistry and how they interact with sunlight.

Dr. Mazzoleni checked with us recently and shared a photo she took from the ferry as she arrived on day one.  On that particular day the mountain was mostly free of clouds:
