Quantum Dot FRET-Based Probes in Thin Films Grown in Microfluidic Channels
(ACS Publications, 2010-01-14)This paper describes the development of new fluorescence resonance energy transfer (FRET)-based quantum dot probes for proteolytic activity. The CdSe/ZnS quantum dots are incorporated into a thin polymeric film, which is ... -
Gold Nanoparticle−Quantum Dot−Polystyrene Microspheres as Fluorescence Resonance Energy Transfer Probes for Bioassays
(ACS Publications, 2011-01-31)The paper describes the development of highly sensitive particle-based fluorescence resonance energy transfer (FRET) probes that do not use molecular fluorophores as donors and acceptors. In these probes, CdSe/ZnS luminescent ... -
Switched capacitor quasi-adiabatic clocks
(IEEE, 2015-07-30)Clock Distribution Networks (CDNs) in high speed designs can consume 30-50% of the total chip dynamic power. Adiabatic clock circuits can save some of this power, but these depend on a time varying power supply which is ... -
Addition of Fluorescence Lifetime Spectroscopy to the Tool Kit Used to Study the Formation and Degradation of Luminescent Quantum Dots in Solution
(ACS Publications, 2017-02-28)The increasing commercialization of consumer electronic products that make use of II–VI semiconductor quantum dots (QDs) has raised significant concerns about their impact on natural systems and human health once they are ... -
Investigation of phosphorous doping effects on polymeric carbon dots: Fluorescence, photostability, and environmental impact
(Elsevier, 2017-12-05)Carbon dots have arisen as a potential alternative to traditional quantum dots since they fluoresce but are synthesized from sustainably sourced green chemicals. Herein, fluorescent nitrogen-doped polymeric carbon dots ... -
Differential current-mode clock distribution
(IEEE, 2015-10-01)In this paper, we present a differential current-mode pulsed flip-flop (DCMPFF) for low-power clock distribution using a representative 45nm CMOS technology. Experimental results show that the DCMPFF has 47% faster ... -
Malic Acid Carbon Dots: From Super-resolution Live-Cell Imaging to Highly Efficient Separation
(ACS Publications, 2018-06-08)As-synthesized malic acid carbon dots are found to possess photoblinking properties that are outstanding and superior compared to those of conventional dyes. Considering their excellent biocompatibility, malic acid carbon ... -
Low-Power Resonant Clocking Using Soft Error Robust Energy Recovery Flip-Flops
(Springer Nature, 2018-06-27)An energy recovery or resonant clocking scheme is very attractive for saving the clock power in nanoscale ASICs and systems-on-chips, which have increased functionality and die sizes. The technology scaling followed Moore’s ... -
Negative Capacitance Clock Distribution
(IEEE, 2018-09-27)In this paper, we investigate the ever-increasing power issue that is poised to jeopardize the performance and robustness of future low-power microprocessor design. We have observed a tremendous amount of research in ... -
High-Speed On-Chip signaling: Voltage or Current-Mode?
(Taylor & Francis, 2018-10-22)In this paper, we investigate several on-chip signaling schemes. Specifically, we compare different voltage-mode (VM) and current-mode (CM) signaling schemes considering power, performance, and robustness. In addition, we ... -
Resonant Energy Recycling SRAM Architecture
Although we may be at the end of Moore’s law, lowering chip power consumption is still the primary driving force for the designers. To enable low-power operation, we propose a resonant energy recovery static random access ... -
Structure–Property Relationships of Amine-rich and Membrane-Disruptive Poly(oxonorbornene)-Coated Gold Nanoparticles
(ACS Publications, 2018-03-21)The article describes the interactions between poly (oxonorbornenes) (PONs)-coated gold nanoparticles (AuNPs) with phospholipid vesicles and shows that the strength of these interactions strongly depends on the molecular ... -
A Personalized Automated Email Tool to Connect Faculty with Students in Large STEM Courses
(The Chemical Educator, 2019-12-31)Undergraduate student success in science, technology, engineering, and mathematics (STEM) majors often hinges on the satisfactory completion of large gateway introductory courses such as general chemistry. First-year or ... -
