Aim/Purpose:
The purpose of this paper is to offer a systematic review of empirical literature examining doctoral students’ identity development as scholars in the education sciences. We frame our analysis through a constructivist sociocultural perspective to organize our findings and discuss implications for multiple actors and components that constitute the...
University-based makerspaces are receiving increasing attention as promising innovations that may contribute to the development of future engineers. Using a theory of social boundary spaces, we investigated whether undergraduate student users at two university-based makerspaces in the United States viewed these spaces as affording their development as well-rounded professionals equipped...
Compared to conventional amorphous silicon (a-Si) TFTs, amorphous metal oxide TFTs have superior device performance such as
higher mobility, better sub-threshold swing, and lower off-state current. Amorphous metal oxide TFTs have an additional advantage
on the device uniformity due to the lack of grain boundary issues in the poly-Si TFTs....
ZnO nanofilms with four distinctly different morphologies were fabricated by adjusting physical parameters including the flow rate of the solution and rpm of the rotating disk in the continuous flow mircroreactor system while keeping the same chemical precursors, precursor solution concentration, and reaction temperature. Controlled reactive species including colloidal ZnO...
Sintering of nanoparticle inks over large area-substrates is a key enabler for scalable fabrication of patterned and continuous films, with multiple emerging applications. The high speed and ambient condition operation of photonic sintering has elicited significant interest for this purpose. In this work, we experimentally characterize the temperature evolution and...
The model presented herein is the same as that of Leon et al. (2010b), except that it has been
modified to preserve "lake at rest" conditions in sloped prismatic conduits. The results of the
new model (present paper) are identical to those of Leon et al. (2010b) for non-rest conditions....
The protein palmitoylation cycle has been shown to be important for protein signaling and synaptic plasticity. Data from our lab showed a change in the palmitoylation status of certain proteins with age. A greater percentage of the NMDA receptor subunits GluN2A and GluN2B, along with Fyn and PSD95 proteins, were...
We report ultrafast pump-probe spectroscopy examining exciton dynamics in atomically thin MoS2. Spectrally and temporally resolved measurements are performed to investigate the interaction dynamics of two important direct-gap excitons (A and B) and their associated broadening kinetics. The two excitons show strongly correlated interexcitonic dynamic, in which the transient blue-shifted...
We demonstrate terahertz (THz) imaging and spectroscopy of single-layer graphene deposited on an intrinsic Si substrate using THz time-domain spectroscopy. A single-cycle THz pulse undergoes multiple internal reflections within the Si substrate, and the THz absorption by the graphene layer accumulates through the multiple interactions with the graphene/Si interface. We...
As decomposers, fungi are key players in recycling plant material in global carbon cycles. We hypothesized that genomes of early diverging fungi may have inherited pectinases from an ancestral species that had been able to extract nutrients from pectin-containing land plants and their algal allies (Streptophytes). We aimed to infer,...
