Our research is in the area of Organic Chemistry with emphasis on the design, synthesis and study of molecules with novel molecular structure and chemical properties. We are interested in fundamental aspects of electronic structure and its dependence on the size ranging from fraction of nanometer to several nanometers. The objective is to prepare new class of organic materials with magnetic, conducting and optical properties. ...more

A. Pannier

Pannier Lab

A major goal of the Pannier Lab is to understand the mechanisms which render cells responsive to DNA transfer, concentrating on the extracellular environment of the cell, the interaction between cells and biomaterials, as well as the intracellular processes and subsequent signaling involved during nonviral gene delivery. With a better understanding of gene transfer, we expect to use that knowledge to design more efficient delivery systems, which could be used for gene therapy or tissue engineering applications. ...more

R. Saraf

Saraf Group

Study electronic and optical phenomena in mesoscales systems to design and synthesize self-assembled (nanoscale) materials and structures for applications in molecular medicine and electronics. The systems we study are both physical and biophysical. ...more

L. Parkhurst

Parkhurst Group

Research in our laboratory is focused on interactions between DNA, RNA and proteins. Our goal is to understand the step-wise structural and energetic changes associated with these binding events. Dye molecules attached to oligonucleotides and proteins act as reporter groups, sensitively signaling structural changes that occur on the nanosecond time scale. We thus make extensive use of laser-induced fluorescence to monitor protein-oligonucleotide interactions in real time.

Gay

Gay Lab Tab

We are interested in polarized electron and neutrino physics. Our work involves studies of polarized electron scattering from atoms and molecules, the understanding of chiral and dichroic effects in such targets, the development of novel sources of polarized electrons and electron polarimeters, and investigations of the fundamental nature of the electron. Our group is also part of a four-university collaboration, based at the University of Texas, to make direct measurements on the mass of the electron antineutrino. We are funded both by the Low-Energy Nuclear Physics and Experimental Atomic, Molecular, and Optical Physics programs in the Physics Division of the National Science Foundation.

S. Kidambi

Kidambi's Focus Lab

Our research program focuses on the development of novel nanostructured materials with highly controlled architectures and chemistries for tissue engineering and drug delivery applications. The materials developed through this research will address some of the key challenges of regenerative medicine and drug delivery. We plan to exploit classical engineering principles to increase understanding of the ways that cells receive information from materials, and what happens to cell function over time when assembled within 3D microenvironments. We will have a strong emphasis on multidisciplinary collaborations with chemists, biologists, material scientists and neuroscientists. Our ultimate goal is to design novel surfaces for understanding the underlying biology of neurodegenerative diseases such as Alzheimer’s and engineer novel therapeutic approaches. ...more

K. Belashchenko

Belashchenko Group

Our research is in computational electronic theory of solids. Usually we use so-called first-principles techniques which are based in one way or another on the solution of the quantum-mechanical Schroedinger equation for the given material or nanostructure. The solutions may be used to calculate various measurable properties such as the atomic structure, magnetization, electric resistance or resistivity, response to external fields, spectroscopic properties, etc. Because the general equations are unsolvable, physical insight and clever approximations are always needed to make the calculations manageable. Many different techniques are available, and new ones are constantly being developed. Our work includes both application of appropriate methods to problems of fundamental and practical interest and development of new computational techniques. ...more

M. Schubert

Schubert Group - Complex Materials Optics Network

The group's primary interest is keen development and widest application of ellipsometry for solving contemporary experimental and theoretical problems in physical materials sciences. Current areas comprise Generalized Ellipsometry, Quantum Ellipsometry, Magneto-Electro-Optic Ellipsometry, Terahertz and Infrared Ellipsometry, time-, spatial-, momentum- and frequency-resolved Ellipsometry. Ongoing research is devoted to semiconductors and layered semiconductor nanostructures and we address problems related to magnetism, ferroelectricity, multiferroism, charge transport and quantum confinement, for example.

G. Larsen

Larsen's Catalytic and Sorbent Materials Group

Dr. Larsen's group works on a variety of projects related to catalysis, adsorption, and nanostructured materials design. By means of micro- and nano-fabrication methods based on electrohydrodynamic forces, we are currently designing nanocapsules, nanotubes, and nanofibers of inorganic, hybrid (organic/inorganic), organic, and biological materials for a variety of applications. Specifically, these submicron structures can be utilized for preparing nanovesicles for controlled release applications, reinforced composites, sorbents and catalysts, and tissue scaffolds. Being highly interdisciplinary, some of the work is done in collaboration with faculty and professionals affiliated with several foreign and domestic academic institutions and industry.

 

F. Bobaru

Bobaru's page Trauma Mechanics Research

Our research group is focused on developing computational methods and tools that can provide solutions for very complex and difficult problems for which analytical or experimental methods either do not exist or are too expensive to perform. We apply our computational methods to problems ranging from nano-materials and biological systems, to heat and mass transfer or impact and fragmentation in ceramics. In particular, fields of current focus are: peridynamics for fracture and impact, modeling of nanostructured materials, meshfree methods and their applications to shape and material optimization of solids, granular materials and their interaction with vibrating structures, multidisciplinary optimization, inverse problems, adaptive refinement, and multiscale and multiphysics methods. ...more

 

R. Lai

Lai's Research Link

Our research program is comprised of both fundamental and applicational aspects of biosensor research. The main objective of our research involves the design of folding-based electrochemical biosensors, with the goal of developing a portable real-time biosensor for point-of-care diagnosis. Our sensing strategy is to link ligand-induced folding in biopolymers (e.g. peptides, nucleic acids) to a robust, electrochemical signaling mechanism (Figure 1). Unlike most optical-based biosensors, these sensors are reagentless, reusable, and insensitive to non-specific interactions of contaminants, thus allowing them to be employed directly in realistically complex media such as blood serum and urine. ...more

 

A. Gruverman

Gruverman Lab page

The group research is focused on fundamental studies of nanoscale physical phenomena in electronic and polar materials by means of scanning probe microscopy (SPM) techniques. More specifically, research involves application of SPM for nanoscale studies of static and dynamic properties of ferroic domains, scaling behavior of ferroelectric-based devices, electronic properties of polar surfaces, SPM-assisted methods for fabrication of nanostructures and SPM studies of electromechanical and mechanical properties of biocompatible materials and biological systems.

 

X. C. Zeng

Zeng Lab

We employ University of Nebraska-Lincoln Supercomputing facility to carry out virtual experiments and explore behavior of matters under extreme conditions, e.g. under high temperature, high pressure, or in highly confined environments, in which real-world experiments may be impractical or inaccessible. As an example, we have revealed several new forms of ice and silicon, solely based on large-scale computer simulations. At right, we show a snapshot of 2-dimensional "Nebraska Ice"; and below, a snapshot of 1-dimensional single-walled hexagonal silicon nanotube.

The rapid evolution of this group and their global distributions make them ideal biostratigraphic indicators for the Late Triassic through Recent. ...more

 

J. Turner

Turner Ultrasonics & Vibrations Group Video Trauma

The research interests in our group fall under the general topics of wave propagation and vibration. The wave propagation research has been primarily with complex media for which deterministic analysis techniques are either unsuitable or too difficult. Statistical approaches are used for obtaining important microstructural information about these complex materials which include polycrystalline metals, composites, concrete, and geophysical materials. This work has both theoretical/numerical and experimental aspects for materials characterization and nondestructive testing purposes. The ultrasonic experimental work includes studies of concrete, sintered materials, polycrystalline metals and piezoelectric materials with a new topic on measurements of third-order elastic constants. ...more
