Personal Bio:

Ioannis Spanopoulos is an Assistant Professor at the Departments of Chemistry and Chemical, Biological and Materials Engineering at the University of South Florida, FL and he is the director of the SMMARTT center at USF. Research at the Spanopoulos Group focuses on utilizing molecular and crystal engineering for the design and synthesis of next generation, environmentally stable and friendly hybrid materials. These materials feature multiple functionalities, targeting applications such as photovoltaics, spintronics, sensing, gas-separation, solid-state batteries, environmental remediation and photo-catalysis. The Group recently reported the new family of water stable and porous metal halide semiconductors. He has received the 2020 IIN Outstanding Researcher award from the International Institute for Nanotechnology and the 2022 ACS PRF Doctoral New Investigator Research award. He has published 70 peer-reviewed papers in the area of materials chemistry and has 2 patent filings.

Workshop Description:


In the field of Materials Chemistry many characterization techniques are utilized for shedding light on the properties of the corresponding materials. This is absolutely essential in order to understand the fundamental structure-property relationships in terms of optical, electronic and mechanical properties. Two of the most important characterization techniques are the X-ray diffraction and optical spectroscopy. In this workshop we will offer an intensive course on X-ray diffraction and transient absorption (TA) spectroscopy.

Goal / Rationale:

Any graduate student that works in different areas of Materials Chemistry must have a fundamental understating on the principles behind crystallography, X-ray diffraction, and single crystal structure determination. In addition, fundamental knowledge of common spectroscopy techniques would be ideal for determination of the optical properties of the corresponding materials. The determination of the crystal structure allows the direct correlation of the optical properties to the underlying structural motifs. Therefore, understanding the reason behind this performance will allow the design and synthesis of compounds with targeted functionalities (e.g. tunable optical properties). This workshop will cover these 2 essential topics by hosting experts from both areas.

Scope and Information for Participants:

This workshop is a great opportunity for junior researchers and students to participate and Interact with experts in Crystallography and Molecular Spectroscopy towards understudying the principles behind fundamental characterization techniques. Particular focus will be placed on structure property relationships, especially in terms of optical properties. The scope of the workshop pertains to the development of next generation materials and encompasses Chemistry, Materials Science and Physics. The contributors are expected to address the main questions and challenges in materials design, towards the acquisition of multifunctional systems with targeted optical properties.


The workshop "Characterization methods in solid state chemistry" was successfully held on Feb. 17, 2023 at the Department of Chemistry, University of South Florida, presented by Professor Ioannis Spanopoulos. The 14 students attending the workshop were mainly Chemistry graduate and undergraduate students with a diverse research background. There were two lectures, one from Prof. Chavdar Slavov (USF) on Transient Absorption Spectroscopy, and one from Dr. Lukasz Wojtas (USF) on X-ray diffraction and Single Crystal Structure Determination. The workshop showcased current state of the art characterization techniques, data analysis and interpretation.

VISA - United States


In order to ensure the information is correct and up to date, there may be changes which we are not aware of. And different countries have different rules for the visa application. It is always a good idea to check the latest regulations in your country. This page just gave some general information of the visa application.

US Visa Information

The B-1/B-2 visitor visa is for people traveling to the United States temporarily for business (B-1) or for pleasure or medical treatment (B-2). Generally, the B-1 visa is for travelers consulting with business associates; attending scientific, educational, professional, or business conventions/conferences; settling an estate; or negotiating contracts. The B-2 visa is for travel that is recreational in nature, including tourism; visits with friends or relatives; medical treatment; and activities of a fraternal, social, or service nature. Often, the B-1 and B-2 visas are combined and issued as one visa: the B-1/B-2.

Application Items

If you apply for a business/tourist visa, you must pay your $160 application fee and submit the following:

  • A Nonimmigrant Visa Electronic Application (DS-160) Form. Visit the DS-160 web page for more information about the DS-160.
  • A passport valid for travel to the United States with a validity date at least six months beyond your intended period of stay in the United States (unless country-specific agreements provide exemptions). If more than one person is included in your passport, each person desiring a visa must submit an application.
  • One (1) 2 x 2 inches (51 x 51 mm) photograph taken within the last six months.
  • If a visa is issued, there may be an additional visa issuance reciprocity fee, depending on your nationality.

In addition to these items, you must present an interview appointment letter confirming that you booked an appointment through this service. You may also bring whatever supporting documents you believe support the information provided to the consular officer.

Supporting Documents

  • Invitation letter from business or school.
  • Detailed CV or resume including a list of publications.
  • Complete itinerary, including all meetings, conferences, and visits; include names, addresses, and telephone numbers of your hosts.
  • For other materials, please refer to the U.S. Embassy or Consulate website.


Should your application be denied, the organizing committee cannot change the decision of visa officer, nor will CONF-MCEE engage in discussion or correspondence with the visa application center on behalf of the applicant. The registration fee CANNOT be refunded when the VISA application of individual being denied.
