Mobosens: Mobile software platform for concentration measurements on a smartphone
No full textThe development of mobile computing in recent decade enables various innovative applications on smartphones. Mobile applications have advantages over laboratory solutions for quantitative measurements of chemical concentrations in water. First, the cost of a mobile device is more affordable than professional measuring equipment; second, a mobile device is very portable and convenient for performing measuring tasks at multiple locations. In addition, easy access to mobile geographical data on a smartphone potentially extends data extraction and aggregation of measurements to a global level.
We describe MoboSens, a mobile software platform which aims at low-cost and portable concentration measurements for critical chemicals in both drinking water and the human circulatory system. The complete system of MoboSens contains a sensor circuit package and a smartphone application. Specifically, my efforts in this thesis focus on implementing the software interface designed for the circuit package and the cloud data engine for further data processing.Item withdrawn by Laura Spradlin ([email protected]) on 2014-04-28T18:51:18Z

No full textIn this work, hollow dodecahedral carbon structures with abundant N-doping sites and metal nanoparticles (NC-Co-CNTs) based on MOF-derivative materials were designed and prepared as host materials for lithium metal to ensure uniform lithium deposition on a Cu current collector. NC-Co-CNTs have good electrical conductivity, which ensures fast electron transport and Li+ transfer. The carbon nanotubes catalytically derived by Co can promote the uniform distribution of Li+ along the hollow dodecahedral carbon surface and deposition inside the cavity, and the larger electronegativity of N-doped sites and lithophilic sites such as Co nanoparticles can effectively adsorb lithium, inducing the Li+ to be deposited in the form of spherical lithium in a dendrite-free state, inhibiting the growth of dendritic lithium and improving the electrochemical performance of the lithium metal battery. Based on the above advantages, the electrodes of NC-Co-CNT-based symmetric cells present superior cycling performance for more than 1100 h with low overpotential at 1 mAh cm−2/1 mAh·cm−2. Even cycling at high current density of 5 mA cm−2 and high deposition parameters of 5 mAh cm−2, it still cycles for up to 800 h at a relatively low overpotential
Theoretical Investigation of the Charge Transport Properties of the DPTTA p-Type Single Crystal to the Ambipolar DPTTA-F4TCNQ Cocrystal
No full textOur research has been conducted on the charge transport properties of the single-crystal DPTTA and the cocrystal DPTTA-F4TCNQ using the density functional theory coupled with incoherent charge-hopping model. Charge mobility is primarily considered from the combination of reorganization energy and charge transfer integral, which are important parameters in model of the charge-hopping model. The reorganization energy of DPTTA in both single-crystal and cocrystal forms exhibits similar values. Consistent with the properties of super-exchange coupling and direct coupling when under the same type of coupling mechanism, it decreases with increasing distance from the core molecule. We conclude this section by using kinetic Monte Carlo combined with Einstein\u27s equation to derive the charge mobility, and find it to be consistent with the theoretical analysis. In our study, we propose corresponding theoretical guidelines for the rational realization of the ambipolarity of D-A complexes, hoping to contribute to the understanding and rational design of the basic mechanism of D-A complexes
Discrete Elemental Parameter Calibration of Stacking Behavior of Sugarcane Tail Leaf Sieved Material
No full textTo improve the accuracy of discrete element simulation parameters of sugarcane tail-leaf (STL) feed during dust removal and crushing, this study used a combination of physical tests and EDEM software simulations to calibrate the discrete element simulation parameters of crumbs and dust in the feed. Taking the experimental physical stacking angle (SA) as the response value, the second-order regression models of SA and significant factors were established by Plackett-Burman test, steepest climb test, and Box-Behnken test. Variance analysis and interaction effect analysis were conducted. Taking the accumulation angle of 41.27° obtained by physical experiments as the target value, the significant parameters were optimized. The optimal combination of the following parameters was obtained: tail stem-dust static friction coefficient (SFC) of 0.46, tail leaf-dust coefficient of sliding friction (COSF) of 0.205, JKR surface energy of 0.26, and dust-steel collision recovery coefficient (CRC) of 0.338. Through software simulation verification, the average value was 40.81°, and the relative error of the SA with the physical experiment was 1.13%. The results showed that the calibrated parameters are real and reliable, which can provide a theoretical reference for the design optimization of the straw crushing device, feed processing device, and other related components
