The term biophotonics denotes a combination of biology and photonics, with photonics being the science and technology of generation, manipulation, and detection of photons, quantum units of light. Photonics is related to electronics and photons. Photons play a central role in information technologies such as fiber optics the way electrons do in electronics.
Biophotonics can also be described as the "development and application of optical techniques, particularly imaging, to the study of biological molecules, cells and tissue". One of the main benefits of using optical techniques which make up biophotonics is that they preserve the integrity of the biological cells being examined.

Perovskites-based Solar Cells: The challenge of material choice for p-i-n per...Akinola Oyedele
Perovskite-based PV have triggered widespread interest in the scientific community because these materials offer the attractive combinations of low cost and theoretically high efficiency. However, several challenges must be overcome for these relatively new PV materials. Among the many important challenges, one is the choice of materials to be used in thin film PV devices..
Based on fundamental principles of solar photovoltaics, this problem focuses on two aspects of the perovskite system:
1) Based on a planar p-i-n device structure, a potential list of p- and n-type charge collecting layers as well as the conductive contacts that could be used with a promising perovskite absorber material was identified, and a proper justification for the selection of each material in the device was given.
2) Three theoretical p-i-n type solar cells were made with the chosen materials and appropriate conductive contacts.

Over the years upon the evolution in the field of nanotechnology various materials are introduced and its applications are being explored in reality proving its usefulness. Applications of the same in drug/gene delivery systems is being carried out since past decade and unbelievable results are being achieved. However, problem lying in these techniques being either in cellular uptake of the material or the degradability of the material being used. My work shall concentrate upon introducing a biocompatible and inert systems with molecules fabricated on the surface triggering cellular intake. Genetic system implemented in the system shall rely upon the mechanism of Viral genes assisted integration of the "GOI (Gene of Interest)" into the target specific location in the nucleus. And the GOI is also tagged with the Green Fluorescent Protein expressing Gene so as to confirm the presence of integration of GOI into the genome. This method shall provide a fast , reliable and non-invasive method of tracking down the delivery system from the point of injection to until it delivers the cargo.

SWCNT Growth from Chiral and Achiral Carbon Nanorings: Prediction of Chiralit...Stephan Irle
Catalyst-free, chirality-controlled growth of chiral and achiral single-walled carbon nanotubes (SWCNTs) from organic precursors is demonstrated using quantum chemical simulations [1]. Growth of (4,3), (6,5), (6,1), (10,1), (6,6) and (8,0) SWCNTs was induced by ethynyl radical (C2H) addition to organic precursors. These simulations show a strong dependence of the SWCNT growth rate on the chiral angle, θ. The SWCNT diameter however does not influence the SWCNT growth rate under these conditions. This agreement with a previously proposed screw-dislocation-like model of transition metal-catalyzed SWCNT growth rates [2] indicates that the SWCNT growth rate is an intrinsic property of the SWCNT edge itself. Conversely, we predict that the rate of local SWCNT growth via Diels-Alder cycloaddition of C2H2 is strongly influenced by the diameter of the SWCNT. We therefore predict the existence of a maximum local growth rate for an optimum diameter/chirality combination at a given C2H/C2H2 ratio. We also find that the ability of a SWCNT to avoid defect formation during growth is an intrinsic quality of the SWCNT edge.

Nuclear Physics Research
• Extensive experience in analysis and interpretation of complex decay schemes involving data from
gamma, beta, conversion electron, proton and alpha particles from the emission of decaying nuclei.
• Performed in depth studies of collective states in the Cd nuclei, exposing data that revealed thought
provoking inconsistencies with the currently accepted model of Cd as an anharmonic vibrator
displaying U(5) symmetry.
• Performed detailed studies on nuclei beyond the proton drip line to help map the mass surface and
understand the evolution of single particle wave functions and deformations at the drip line. This
work provides experimental parameters to develop solid theoretical models.
• Extensively researched neutron-rich nuclei near the closed Z=50 and N=82 closed neutron shells, to
further understand half lives, isomers, and low-energy levels within astrophysical r-process paths
2. • Generated valuable insights into the evolution of shell structure and shape coexistence in nuclei near
132
Sn through gamma, beta, and conversion spectroscopy in the neutron-rich Ag, Cd, In and Sn
isotopes.

across both internal (ORNL) and external teams (UNIRIB universities).
Technical Development
• Acted as a major contributor to the design, commissioning, and experimenter of the focal plane

scintillator detectors while implementing the digital electronics and data acquisition system to
maximize system functionality
• Played an integral role in the implementation and commission of a new, substantially more robust
digital spectroscopy acquisition system for the DSSD; system consisted of 400 MHz flash ADC's,
where the shape of the signal was digitized and recorded to vastly improve the depth of information
collected, subsequently, the system was routinely used at the Holifield Radioactive Ion Beam Facility
• Used novel ion source techniques and Accelerator Mass Spectroscopy (AMS) to measure U and Th
levels in Cu for the Majorana experiment, which required unprecedented low backgrounds below the
current detection limits of existing assay techniques
• Designed the computer control system for controlling voltages at the multi-pass, time-of-flight, isomer

• Designed a wide variety of parts, connectors, and chambers through CAD programs
Grant Writing, Reporting, and Publications
• Authored the scientific portion of the Field Work Proposals from 1997 through 2014, which has
helped secure the majority of funding ($350K annually) for the University Radioactive Ion Beam
(UNIRIB) consortium, consisting of 6 universities conducting research at HRIBF
• Secured $1.2M in funding by skillfully writing a significant portion of the scientific justification for

continues to be an ongoing international nuclear physics conference series with follow-up meetings
held in Legnaro (2003), Lisbon (2007), Bordeaux (2011) and Lanzhou (2015).
