The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...
The thesis presents a new algorithm and structure that is to be used in conjunction with a specially modified CMOS Gilbert cell mixer to remove time-varying DC offsets in direct conversion receivers. In our approach, the DC offset is detected at the output of the mixer using a dedicated coarse...
Chemical equilibrium is a major factor in many natural and
industrial systems. The ability to predict ionic equilibrium is
extremely valuable in industry in solving problems without the costs
involved in full scale experiments. An example of an application in
the pulp and paper industry is the prediction of non-process...
A continuous amperometric monitor for aqueous sulfite solutions
has been developed employing the electro-oxidation of sulfur (IV)
in 0. 1 M sulfuric acid at a glassy carbon test electrode. The monitor
employs a hydrodynamic flow cell, in which the solution stream
enters the cell through an orifice impinging on the...
The practice of green infrastructure is synonymous with collaborative partnerships. Expertise from engineers, land care professionals, planners, and natural resource consultants are often required for successful project implementation. Traditionally, these professionals perform their responsibilities in their disciplinary “silos,” but this evolving area of sustainable development is creating a demand for...
This paper is concerned with the application of
hierarchial and parallel computing structures to digital
data communications processing in a multi-access telecommunications
environment. Designs are analyzed and
evaluated in terms of data collected from remote access
tele-communications traffic and in terms of the application
to several processing problems in the...
Perturbed Angular Correlations (PAC) spectroscopy is an effective
local probe technique often employed in the characterization of defects or
phase transitions in any of a variety of materials. This technique relies
upon the ability of probe nuclei to function as gauges of the magnetic
fields and electric field gradients local...
Recent studies have indicated that nickel gallium alloys can be effective for the catalytic hydrogenation of CO2 to methanol. To simplify the characterization of NiGa catalysts, we are developing model systems using NiGa thin films. We prepared NiGa thin films by RF magnetron sputtering using an equiatomic alloy target, followed...
