Group Introduction

Welcome to the Functional Materials Design & X-ray Diffraction Laboratory at the Department of Chemistry & Biomolecular Science at Clarkson University!

Dr. Wriedt’s research activities are mainly focused at developing new strategies for the design and synthesis of advanced functional solid-state materials from molecular building blocks and advancing the understanding of their structure-property relationship.

His group at Clarkson University works towards the development and characterization of new metal-organic frameworks (MOFs) and activated carbons whose applications address some of our society’s most challenging needs. Specific fields of interest are listed below.

  • Clean Energy Alternatives: Materials for on-board H2 and CH4 storage systems for automotive applications
  • Reduce Greenhouse Gas Emissions: Materials for CO2 capture and sequestration from flue gas streams
  • Stimuli-Responsive Spintronics: Materials for sensing and ultra-high data storage applications
  • Environmental Water Treatment: Materials for selective removal of pollutants from waste- and groundwater
  • Electro- and Photochromic Switches: Materials for the development of new smart-glass technologies

Wriedt Lab Leads PFAS Research

October 2021: Wriedt Lab spearheaded the exploration of using MOFs for the removal of per- and polyfluoroalkyl substances (PFAS) from aqueous environments. PFAS are an emerging class of contaminants raising increased levels of concern due to their toxic, bioaccumulative, and persistent nature, but their removal using current technologies remains challenging. Two PFAS@MOF papers were published. Big thanks to our fantastic collaborators from the groups of Drs. FarhaHolsenThagard and Trivedi to make this work possible.

Wriedt Lab Develops Advanced Sunscreens with Estée Lauder Companies

September 2021: Dr. Adarsh Nayarassery Narayanan joined the Wriedt Lab as Postdoctoral Research Associate to explore MOFs as advanced sunscreen materials. We are very excited about this new industrial collaboration to work with Estée Lauder Companies.

Wriedt Lab Hosts Crystallography Workshop with Dr. Peter Mueller 

August 2021:  After a successful nationally recognized single-crystal x-ray diffraction workshop in 2019, Clarkson’s Chemistry & Biomolecular Science Department hosted a second Crystal Structure Refinement Workshop in August. Mario Wriedt, Associate Professor of Chemistry & Biomolecular Science and CAMP Distinguished Professor at Clarkson University, together with world-renowned crystallographer Dr. Peter Mueller of the Massachusetts Institute of Technology, offered an intensive 5-day Single Crystal X-ray Diffraction (SCXRD) workshop, Getting the Best Structure from your Diffraction Data at Clarkson University’s Main Campus in Potsdam NY. 

The relatively small experimental effort required for a routine X-ray structure determination, combined with a revolution in data processing, has led to a tremendous increase in the use of single crystal X-ray diffraction, making it one of the most widely used methods of structure elucidation. This means that even inexperienced users can perform their own structure determinations. The workshop was designed to teach students, faculty and researchers working in the area of materials science to avoid, recognize or correct problems that emerge during the structure determination process.

“We were pleased to have a safe in-person event after such a long time of virtual meetings, and no surprise, our workshop was booked to full capacity. All participants were eager to advance their crystallography skills. Eventually, a full week of hands-on structure refinements, with complementing lectures, made the event a great success. All feedback received was outstanding and we look forward to planning our next workshop for 2023,” Wriedt said.

There were 34 participants, seven from Clarkson University and 27 students, faculty, and staff from universities as close as Syracuse, NY, and as far away as the University of Southern California and Texas A&M.

Professor Wriedt and his co-instructor Dr. Peter Mueller share a passion for crystallography, and both have robust backgrounds in related educational and research areas. Mueller has offered this workshop all over the world for many years.

This event would not have been possible without the generosity of our sponsors and a fantastic organizational team.

Dr. Wriedt Awarded Corning Grant for Smart Window Research

April 2019: Dr. Wriedt has been awarded a grant funded by Corning Incorporated for his research into electrically activated molecular assemblies. These original chemicals can be used to make smart windows.

Smart windows, which are already used on some aircraft and commercial buildings, are windows whose transmission properties change when voltage, light, or heat is applied.

“If you start with a transparent window and apply an electric potential, you can alter the contrast ratio of the window. This process controls how much light is reflected or absorbed and eliminates the need for blinds or shades. Ultimately, it is an energy-efficient process that can reverse the change in transparency by applying a potential,” Wriedt said. “This technology is fairly new yet well established. However, certain limitations do exist. We aim to address them using our research.”

Wriedt’s group at Clarkson specializes in the rational design and synthesis of molecular assemblies, including advanced crystalline porous materials that form multi-dimensional networks suitable for a wide variety of applications. While such materials are typically regarded as insulators, through fine-tuning and modifications, Wriedt and his team have found a way to induce conductivity and make their materials electrochemically-active.

“Our materials operate through redox chemistry and allow for fast switching times between transparent and opaque states with no loss of the electrochemical behavior or structural integrity after successive cycles, which make them adaptable to smart window technology,” Wriedt said. “In the future, smart windows will have an abundance of practical applications, including use in residential homes and commercial buildings.”

This grant from Corning Incorporated will enable new and exciting ventures for Wriedt and his team of 15 student researchers including graduate and undergraduate students.

Dr. Wriedt receives Tenure and Promotion to Associate Professor

February 2019: Clarkson University President Tony Collins has announced that Mario Wriedt has been granted tenure and promoted from assistant professor to associate professor of chemistry & biomolecular science in the School of Arts & Sciences.
