New Advanced Materials Characterization Institutional Core

Dr. Paul Baker
Dr. Paul Baker, Director

The Advanced Materials Characterization (AMC) Core has been selected an institutional research core (Director: Dr. Paul Baker and co-Director: Dr. Vinoy Thomas). It will be a part of the fifteen cores that are supported centrally by the office of Vice President for Research. The AMC Core will provide a broad range of services related to the research and development of materials. Our services will cover the analysis of basic properties of materials such as the structure, composition, and hardness. The types of materials to be analyzed include biomaterials, nanomaterials, metals, ceramics, thin films, composite materials, and semiconductors.

Dr. Vinoy Thomas, Co-Director

The AMC Core will include the University’s only scanning electron microscope (SEM), which provides high resolution images of surfaces of a broad range of materials, including soft matter (biological samples) and has elemental analysis capability (EDX). The x-ray photoelectron spectrometer (XPS) is a powerful surface analysis (probing depth of only 3-10nm) instrument that provides elemental composition and chemical bonding information with small spot size (minimum 10 micrometers) and surface mapping capability. The multipurpose X-ray diffractometer (XRD) is a state-of-the-art instrument purchased in 2018 that provides information on crystal structure and phase identification, particle size and shape analysis (SAXS), thin film analysis, epitaxial layer analysis, and can be upgraded to include even additional capabilities. The micro-Raman spectrometer is a high-resolution spectrometer that analyzes the vibrational modes of the material to provide information about the molecular structure of a material. The nanoindenter measures the hardness of a material near the surface and can measure polymers and thin films. These materials growth and characterization facilities are being combined and proposed as a single core to provide materials characterization under one managed facility and serve as a catalyst for innovative materials discovery at UAB. One of the key strengths of the core will be the broad support from industry usage as well as the multi-departmental use. This multi-disciplinary approach to characterization of advanced materials is a part of the UAB research mission.

 

NSF EPSCoR Program Harnesses Non-thermal Plasma Processing for Nano-structuring 3D Printed Tissue-Scaffolds:

Dr. Vinoy Thomas, Materials Science and Engineering

A UAB team led by Dr. Vinoy Thomas, Department of Materials Science & Engineering, has surface engineered 3D Printed polymeric soft biomaterial scaffolds by an in-situ robust synthesis of nanoparticles using low temperature dusty plasma.

The proof-of-concept communication published in ACS Applied Nano Materials, reports a rapid and easy method for nanoparticles (SiNp) synthesis from a liquid precursor into dusty plasma and deposition of them onto 3D printed polymer. “Non-thermal plasma has emerged as a viable method for surface engineering soft materials and biomaterials”, says Dr. Vineeth Vijayan, (first author of the publication), “and we have successfully utilized non-thermal plasma for making super-hydrophilic and blood-friendly materials surfaces in our previous publication in Journal of Materials Chemistry”.

As part of the NSF supported EPSCoR collaborative CPU2AL program, the new method we reported has many appealing attributes:

    1. It is a single step greener and cost effective process
    2. The radiofrequency plasma reactor can be an ideal scalable technology for industries to produce and modify the surface of various biomedical scaffolds/devices with SiNp, and
    3. This method can simultaneously modify the 3D printed scaffolds with SiNp for biomedical applications (bone tissue engineering) and also sterilize them.

The future aspects of this present work will deal with (I) functionalization and attachment of SiNp with biochemical moieties by using volatile amino acids in the plasma phase and (II) strategies for preparation titanium dioxide nanoparticles and nanowires via plasma process which in turn could be used for decontaminate corona virus during the current COVID-19 pandemic.

UAB collaboration in non-thermal plasma processing shows promise

An interdisciplinary team of researchers at the University of Alabama at Birmingham (UAB) has developed a new method designed to improve the surface characteristics of Teflon, or polyhetrafluorethylene (PTFE). This method has the potential to address challenges associated with PTFE for blood-contact applications—specifically poor endothelial cell growth and the risk of blood clots.

Atomic Force Microscope for Materials Research and Education

Atomic Force Microscope for Materials Research and Education

Eugenia Kharlampieva
Dr. Eugenia Kharlampieva, Chemistry

Congratulations to Dr. Eugenia Khamlampieva on her new National Science Foundation grant for MRI:  Acquisition of an Atomic Force Microscope for Materials Research and Education.

Dr. Kharlampieva says:  This Major Research Instrumentation award supports the University of Alabama at Birmingham to acquire an atomic force microscope for interdisciplinary materials research and education. This microscope supports a diverse, multi-departmental research in soft materials ranging from soft synthetic hydrogels to relatively dense composites and biological structures. The instrument will be located at UAB Department of Chemistry and will combine the capabilities for high-resolution and high-speed imaging with quantitative nanomechanical mapping.

The ability to acquire multifunctional, high-resolution data under a wide range of operating conditions allows for studies on a broad spectrum of dry and hydrated samples. The types of samples extend from synthetic networks, polymer composites, nanodevices, to cell membranes and tissues. The common theme among these samples is that they all involve soft materials, i.e., synthetic polymers, biological structures, or combinations of the two. An increased ability to characterize state-of-the-art nanomaterials results in an enhanced fundamental understanding of the structural properties of soft materials and the composition at their surfaces. This includes the effect of the surface morphology on the physical, biological, and chemical characteristics of the materials.

The understanding enables transformative research for the development of new materials in tissue regenerative therapies, controlled drug delivery, molecular sensing, and related biotechnologies. The atomic force microscope will also play a vital role in student education in the fields of chemistry, materials science, biomedical science, and biomedical engineering. A high-caliber research environment is vital to the regional economy in Central Alabama through raising community awareness toward biomedical and soft-materials technologies.

NSF Renews Research Experiences for Undergraduates Program

Renewal Effective March 9, 2018

PER the NSF website:   The University of Alabama at Birmingham (UAB) will host a Research Experiences for Undergraduates (REU)-site in experimental and computational materials research. This REU-site project plans to recruit students from underrepresented groups and academic institutions where research opportunities are limited. This project offers a broad range of interdisciplinary materials research experiences to undergraduate students with a diversity of backgrounds in physics, chemistry, applied mathematics, and engineering. The undergraduate students will gain experience in materials synthesis, materials characterization and computer modeling and simulations during their ten-week research stay at UAB campus. The scientific research projects have been specifically developed for undergraduate students by an interdisciplinary team consisting of science and engineering faculty at UAB. This project will continue to provide lecture series and workshops in materials growth and characterization, research ethics, and professionalism, innovation and entrepreneurship, and preparation for graduate school to all participants. Our REU participants will publish their findings in peer-reviewed journals and/or present at professional meetings leading to a broad dissemination of new knowledge created in the undergraduate research projects.

TECHNICAL DESCRIPTION

REU research projects are organized in four research clusters: (1) materials under extreme conditions (2) materials for energy applications, (3) materials for sensors and laser applications, and (4) biomaterials for implants, tissue engineering, and drug delivery applications. The undergraduate research projects contribute to fundamental understanding of phase transformations and degradation of materials under extreme conditions, novel materials for fuel cells, materials for nanoscale sensors and mid-IR lasers, and 3-D printed biomaterials and stimuli-responsive polymers. Some research projects will also involve the use of national x-ray synchrotron facilities and neutron diffraction facilities in materials research. The undergraduate student projects have short-term achievable milestones, while simultaneously contributing to longer-term scientific goals and technological applications. Our teaming arrangement of REU participants with faculty and graduate students, giving poster and oral presentations, writing a research-style paper, and attending training seminars in scientific communications and ethics will help REU students see the “big picture” of what it takes to develop into a “research scientist” with the critical skills needed for analyzing, interpreting and presenting scientific data.

This award reflects NSF’s statutory mission and has been deemed worthy of support through evaluation using the Foundation’s intellectual merit and broader impacts review criteria.
