New emission inventory reveals termination of global dioxin declining trend
Journal of Hazardous Materials, 2022Accurate estimates of spatiotemporally resolved Polychlorinated dibenzo-p-dioxins (PCDD/Fs, or dioxins) emissions are critical for understanding their environmental fate and associated health risks. In this study, by utilizing an empirical regression model for PCDD/Fs emissions, we developed a global emission inventory for 17 toxic PCDD/Fs congeners ...

Revealed and Stated Preferences for CO2 Emissions Reduction: The Missing Link
SSRN Electronic Journal, 2015Abstract In this paper we combine data collected from two strands of literature dealing with revealed preferences expressed by conventional vehicle drivers for fuel price variation and stated preferences expressed by consumers for alternative fuel vehicles.

Phonon Line Emission Revealed by Self-Assembly of Colloidal Nanoplatelets
ACS Nano, 2013We show that colloidal nanoplatelets can self-assemble to form a 1D superlattice. When self-assembled, an additional emission line appears in the photoluminescence spectrum at low temperatures. This emission line is a collective effect, greatly enhanced when the NPLs are self-assembled.

Revealing SRAM memory content using spontaneous photon emission
2016 IEEE 34th VLSI Test Symposium (VTS), 2016This paper presents a novel methodology that allows one to reveal SRAM memory content by observing the spontaneous photon emission collected from the backside of the chip. This method is based on our proposed tester-based optical methodology [1] that combines different test patterns, time-integrated and time-resolved emission measurements to localize ...

Nano Letters, 2015
The origin of photoluminescence in carbon dots has baffled scientists since its discovery. We show that the photoluminescence spectra of carbon dots are inhomogeneously broadened due to the slower relaxation of the solvent molecules around it. This gives rise to excitation-dependent fluorescence that violates the Kasha-Vavilov rule.

Electron Emission from Pentagons on a Carbon Nanotube Tip Revealed by Field Emission Microscopy
MRS Proceedings, 2000AbstractField emission of electrons from multiwall carbon nanotubes (MWCNTs) has been investigated by field emission microscopy (FEM) in an ultra-high vacuum chamber. An MWCNT whose tip is capped by curved graphite layers gives a FEM pattern consisting of 6 bright pentagons when the surface of the nanotube tip is clean.
