Project on Diamond and Nitrogen Vacancy Center Photophysics Awarded by NSF
February 27, 2023
Diamond with its amazing physical properties usually associated with fine gem stones is also an emergent material in photonics, biolabeling and quantum sensing. The surface of diamond, while notoriously difficult to modify, is the target of a recently awarded NSF grant to the lab of Prof. Abe Wolcott (NSF LEAPS). Investigating new surface chemistry and its effect on electric field sensing by the fluorescent nitrogen vacancy center (NVC) are the main aims. NVCs are very sensitive to magnetic and electric fields and can be used in applicationa such as chemical analysis (similar to NMR) and pH sensing. Because the NVC is also a quantum bit, or qubit, it can be used in encoding and transmitting information. The project should have a broad impact in the field of materials science and those using spin defects in diamond for quantum detection. The work will be carried out by an ultradiverse team of researchers and in collaboration with the Black Leadership and Opportunity Center or BLOC.
Prof. Grazioli Publishes an Article on Instructional Activities using his Fluid Simulation Software
February 7, 2023
Prof. Grazioli recently published a peer-reviewed article with 4 SJSU student co-authors in the ACS Journal of Chemical Education titled "Foregrounding the Code: Computational Chemistry Instructional Activities Using a Highly Readable Fluid Simulation Code." The article demonstrates two instructional activities for teaching computational chemistry to students that emphasizes students working directly with computer code. This approach is motivated by Dr. Grazioli's teaching philosophy that, just as students of organic chemistry need experience working directly with the chemicals and laboratory equipment used by professional organic chemists, so too do students of computational chemistry need experience with one of the professional computational chemist's core skills: writing code. The activities are centered around a Lennard-Jones fluid simulation code that Dr. Grazioli wrote in Python to maximize the readability of the simulation code for students. The article is freely available to the public through the CSU's open publishing agreement with the CSU, and the simulation code and Jupyter Notebook for the activity are freely downloadable from Dr. Grazioli's GitHub page.

Professor Wang Receives NIH Grant
Prof. Ningkun Wang was awarded an NIH SC2 research grant to study the allosteric regulation of SIRT1. SIRT1 is an NAD+-dependent protein deacetylase that has been shown to play a significant role in many biological pathways including insulin secretion, tumor formation, lipid metabolism, and neurodegeneration. For this reason, SIRT1 has been identified as a potential therapeutic target, where the regulation of SIRT1 activity could combat diseases such as diabetes, cancer, and neurodegenerative diseases. This progress has been hampered by insufficient understanding of the molecular mechanism of the regulation of SIRT1 activity. Prof. Wang’s lab aims to understand the regulatory allosteric interactions between the N-terminal domain and SIRT1’s catalytic core. Using biochemical and biophysical methods to clarify how the activity of SIRT1 is altered in various biological pathways and disease states will enable the targeted modulation of SIRT1 activity as a therapeutic method. The project will also provide insight into how other allosterically regulated enzymes function in the cell.

Prof. Radlauer Awarded CSUPERB Grant
Prof. Madalyn Radlauer was awarded a CSUPERB New Investigator Grant in Spring 2018. The funded project is inspired by the question: Can we mimic the macromolecular environment of an enzyme with an organic polymer to achieve effective catalysis? Enzymes, biological catalysts that accelerate reactions, promote numerous impressive reactions in nature. For example, transformations like selective methane oxidation have the technological potential to revolutionize our fuel economy. Thus, Prof. Radlauer turned to nature for inspiration, aiming to mimic the chemical transformations made possible by enzymes. Enzymes generally include an active site – where the reaction occurs – embedded in a larger structure, which provides stabilizing forces to promote the desired reaction. To access enzyme-like activity, the lab hypothesizes that these stabilizing interactions must also be mimicked. This task is nontrivial and remains a significant challenge. The proposed work aims to address the challenge of reproducing secondary interactions by embedding a small molecule “active site” within a larger synthetic scaffold to mimic bacterial enzymes that convert greenhouse gases into useful fuels. In addition to a deeper understanding of enzymes and their structures, success with this type of synthetic system might allow technological leaps for the fuel economy since we would be better able to transform greenhouse gases into viable fuels or industry-relevant chemicals.

Professor Madalyn Radlauer Joins Chemistry Department
Prof. Madalyn Radlauer will be teaching courses in inorganic, polymer and general chemistry. As both an organometallic and a polymer chemist, she is looking forward to combining these two areas in her lab, studying small molecule catalysts in macromolecular environments. Like traditional organometallic chemists, students in her lab will synthesize catalysts to lower the activation barrier for challenging reactions relevant to the fuel economy, but these catalysts will then be appended to polymers. Thus, the small molecule catalysts will work as active sites within a larger scaffold, similar to a protein or enzyme. The polymers’ ability to alter catalytic activity will be explored, where we expect that this biomimetic approach will have significant effects.
Professor Ningkun Wang Joins Chemistry Department
Prof. Ningkun Wang will be teaching courses in biochemistry. With a background in protein interactions, Prof. Wang’s research combines biochemistry and biophysical methods to study indirect allosteric effects on the activity and substrate specificity of enzymes. The general goal of the lab is to study the “supporting actors” in biology that play a major role in the story and to learn how they go about doing that.
Specifically, the lab is interested in studying SIRT1, an enzyme that affects gene expression by de-acetylating transcription factors and histones. SIRT1 has a large, unstructured N-terminus domain that is not directly involved in enzyme catalysis, but regulates the catalytic activity and substrate specificity. The lab will seek to elucidate the mechanism of this allosteric effect by studying the interactions between the N-terminus domain and the enzyme catalytic core.

Professor Chester Simocko Joins Chemistry Department
The chemistry department welcomes Prof. Chester Simocko to the department, where he will be teaching courses in organic and polymer chemistry. Prof. Simocko's research bridges the gap between organic chemistry and polymer science. He studies structure-property relationships in polymer systems by considering a desired property (mechanic strength, melting temperature, ion conduction, etc.) and determining how polymer structure affects that property. The lab controls polymer structure by growing a polymer from a surface to create polymer brushes and by making precise polymers and block copolymers for tailored self-assembly via alternating diene metathesis polymerization. Some of the students working on this effort in the Simocko lab are shown above: From left to right: Paul Abarquez, Sandy Rosa, Alexis Sarabia, Andrew Pham, Melvina Lu, Natsu Okuda, Bryan Chin (front), Josh Chen (back), Hamdy Yahya.

Professor Miller Conrad Awarded an NIH Grant to Investigate Resistance in Pseudomonas aeruginosa
April 4, 2016
Prof. Laura Miller Conrad was awarded an NIH SC3 Grant to investigate and block antibiotic resistance in Pseudomonas aeruginosa. The bacterium is the leading gram-negative cause of secondary infections in hospitals. Few treatments successfully clear the infection and resistant strains are increasingly encountered. One class of last-resort drugs currently used are cationic antimicrobial peptides (CAPs) like colistin and polymyxin B. Alarmingly, CAP-resistant strains have also been encountered, threatening the efficacy of these life-saving treatments.
The positively-charged CAPs enter the bacterial cell by electrostatic attraction to the negatively-charged outer membrane of P. aeruginosa, followed by disruption of the membrane. Once inside, the drug binds intracellular targets, killing the bacterium. In resistant strains, P. aeruginosa modifies its outer membrane to become less negatively charged, preventing uptake of the antibiotic. With the grant, the Miller Conrad lab will aim to inhibit a biosynthetic enzyme in the modification pathway, forcing the bacterium to maintain a negatively-charged outer membrane and to remain susceptible to CAP treatment. A successful inhibitor could be used in a combination therapy with the CAP antibiotic. Ken Choi and Sarah Matthews shown above are among the students working on the project.
Professor Rascón, Jr. Awarded an NIH Grant to Study Aedes aegypti Midgut Proteases
February 1, 2016
Prof. Alberto A. Rascón, Jr. was awarded an SC3 research grant from the NIH. The project will investigate the role midgut proteases play during the blood meal digestion process in the virus-carrying Aedes aegypti mosquito. The mosquito specifically feeds on humans to obtain the nutrients needed for the egg laying process, and it is this blood-feeding behavior that facilitates the spread of blood-borne pathogens including Yellow fever, Dengue fever, Chikungunya, and the Zika virus, which has recently emerged in the Americas. At the moment, the only way to minimize pathogen transmission is through mosquito (vector) control. Current strategies include the use of insecticides, which have proven effective in reducing the mosquito population and slowing down pathogen transmission. However, there has been an increase in Ae. aegypti mosquito resistance to available insecticides and with increasing world population, global warming, urbanization, and the lack of other effective mosquito control strategies, the mosquito population will continue to grow. As a result, we will likely experience higher incidences of Dengue, Chikungunya, and Zika infections. The strategy being investigated in the Prof. Rascón, Jr. lab is to target the proteolytic enzymes involved in the blood meal protein digestion process, which should have a negative affect on egg development, reduce the mosquito population, and hence reduce pathogen transmission.

A new gas chromatography/mass spectrometry (GC/MS) instrument was donated by the Santa Clara Valley Water District and will be used in Prof. Roger Terrill’s CHEM 155 class. This is the second donation from SCVWD - the first was an inductively coupled plasma-optical emission spectrometer system (ICP-OES).
Professor Kelly Receives NSF Grant to Develop a Visualization Framework for Chemical Reactions
October 1, 2015
Prof. Resa Kelly was awarded a $265,924 grant from the National Science Foundation – Division of Undergraduate Education - IUSE Program to design effective strategies to develop and present molecular visualizations that support student learning in General Chemistry. The framework will present students with a video of experimental evidence followed by animations in variance to each other. The student will be charged with critiquing the animations in connection to the experimental evidence to decide how the animations are similar to or different from the evidence and each other. Ultimately, they will be asked to reflect on the accuracy of each animation. The understanding and insights revealed through this endeavor, regarding how visualizations can enhance student success, will be of significant value to educators across a wide range of scientific disciplines, from biology, to earth sciences, to physics and more.
