Prof. Abhay Deshpande works in experimental high energy nuclear physics. His current
research focuses on understanding the contributions of quarks, antiquarks and gluons
to the proton's spin using the PHENIX detector and high energy polarized proton beams
at the Relativistic Heavy Ion Collider (RHIC). The property of "spin" has played a
crucial role in the development of our understanding of physics in the past 100 years.
In fact, arguably, the 20th century could be called the "Century of Spin Surprises"
Physico-chemical properties of nanocatalysts, structure-property function relationships
in disordered systems, mechanisms of catalytic reactions, mechanisms of work of electromechanical
materials (piezo-, ferro-, pyro-electrics and electrostrictors. Use of synchrotron-based
techniques in materials characterization (x-ray absorption (XAFS) and emission (RIXS)
spectroscopy, x-ray diffraction). Development of new in situ/operando techniques for
studies of functional nanomaterials.
We are interested in studying the properties of the dense nuclear matter created in
elativistic heavy ion collisions. Under extremely high temperature and density, such
matter exist in the form of quasi-free quarks and gluons (Quark-Gluon Plasma or QGP),
whose interactions are scribed by the Quantum ChromoDynamics theory (QCD). We seek to recreate and study QGP in the laboratory and to understandits
underlying QCD theory. Our research is carried out at the Relativistic Heavy Ion Collider at BNL and at the Large Hadron Collider at CERN. Our group is involved with the PHENIX and ATLAS experiments respectively, at each of these accelerator facilities
Materials Chemistry, Solid State Chemistry: Periodic solids provide the backbone of
the high-tech industry due to their amplification of the interactions between individual
atomic and molecular building blocks assembled within their crystalline lattices.
This group focuses on designing functionality into crystalline solids using elemental
substitution and structural control to fine-tune the energy levels of bulk materials.
Our expertise in materials synthesis, structural characterization, and physical properties
measurements allows us to tackle all aspects of this “internal design” process.
Dmitri Kharzeev is interested in all aspects of the modern theory of strong interactions
- Quantum Chromo-Dynamics (QCD), and its applications to the description of experimentally
accessible phenomena. He is closely involved in theoretical research related to the
programs at Relativistic Heavy Ion Collider at BNL and Large Hadron Collider at CERN.
In particular, he studies the ways in which the underlying quark-gluon structure of
hadrons and nuclei determines the dynamics of their interactions and the salient features
of the visible Universe. Many of these features stem from topology of non-Abelian
gauge theories that form the current Standard Model of the physical world. Dmitri
also believes that all sub-fields of physics are deeply connected, and cross-disciplinary
interactions are necessary for the advancement of science. For example, he argues
that topology holds the key to understanding many universal dynamical properties of
systems at vastly different scales, from femto-meter (quarks and gluons of QCD), to
nano-meter (e.g. topological insulators and graphene), to parsec (e.g. magnetic helicity
and polarization of cosmic microwave background).
The clouds and radars research group focuses on the physical understanding of the
atmospheric component of the hydrological cycle and the improved representation of
cloud and precipitation processes in global, regional and cloud scale numerical models.
Our group is also interest in the use of radars in weather and climate research, from
severe weather nowcasting to cloud-scale processes.
Synergetic remote sensing observations from both space-based and ground-based sensors and their clever use through the development of new inversion algorithms and adaptive sampling strategies constitute our approach for probing clouds and precipitation in their natural environment. As part of our research we use a wide variety of observational platforms, however, millimeter wavelength radars are our primary observing tool for diagnosing the structure, kinematics and microphysics of clouds and precipitation.

The advancement of battery systems with high energy and power densities remains a
lynch pin for new generations of energy storage. The full utilization of renewable
energy sources such as wind, photovoltaic, hydroelectric, and geothermal power depends
on the ability to store energy as in many cases the renewable energy is generated
on an intermittent basis. Additionally, portable electronics, hybrid vehicles, electric
vehicles, biomedical devices, and aerospace applications demand advanced batteries
that can perform safely over many years. Finally, the way in which communities handle
power demands through power grids may be affected significantly by new developments
in energy storage. Specific areas of research. For next generation primary and secondary
battery applications demanding long life, high energy density and high power, new
strategies are needed for the rational design of electroactive materials and the concomitant
engineering associated with battery design. Professor Takeuchi’s research efforts
are collaborative in nature, involving scientists with a variety of research expertise.
For example, we have an on-going research interest in the structure / function relationships
among electroactive materials and redox properties as related to electrochemical energy
storage. We also are actively involved in the synthesis of new electroactive materials
and the subsequent analysis involving a variety of chemical and physical properties
of materials. Further, we conduct fundamental mechanistic studies involving the complex
interplay among redox processes, ion transport, and electrode precipitation / dissolution
that are critical to the electrochemistry associated with battery science.

DYNAMICS AT SURFACES: Our research is aimed at providing a molecular level understanding
of the energetics, dynamics and morphology-dependence of elementary surface reactions
that play key roles in energy-related catalysis. Specifically, we are interested in
systems involving simple feedstock chemicals (e.g., H2, CO, CO2, O2, CH4), the selective
oxidation of C1 and C2 molecules (e.g., CH3OH, C2H4) and reaction systems that have
environmental impact (e.g., De-NOx, De-SOx). We approach these problems from a chemical
physics perspective in which experiments are designed to probe the adsorbate-metal
potential surface and the dynamical paths that lead to reaction. Our experimental
program makes extensive use of lasers for both state-selective detection of desorbed
products and the photo-initiation of surface processes such as desorption, diffusion,
dissociation and reaction. Current studies are focused on understanding the photoinduced
reactions on semi-conducting surfaces such as titania (TiO2); whose photoactivity
is widely used for removing organic pollutants from air and water, for anti-fogging
and self-cleaning surfaces and as a potential photocatayst for solar water splitting.
