D-23: A Novel Electrochemical Sensor for Determination of DNA Damage Biomarkers in Biological Fluids using Two-dimensional (2D) Layered Nanomaterial (Mxene) Covered Binary Metal Sulfide Nanocomposite: Sea-Fue Wang1; Govindasamy Mani1; 1National Taipei University Of Technology
To explore a novel and two-dimensional (2D) layered nanomaterial (mxene) covered binary metal sulfide (mxene@CuMoS2) as an electrode material by hydrothermal technique. Herein, novel nanocomposite is successfully characterized by various characterization analysis (FESEM, HRTEM, XRD, XPS and EIS). The nanomaterial is employed as a high sensitive electrochemical sensor for the determination of cancer and oxidative biomarker (8-hydroxy-2’-deoxyguanosine and 4-nitrotyrosine). The results demonstrated that the mxene@CuMoS2 modified screen-printed carbon electrode. The high sensitive properties of the optimized flower like CuMoS2 modified nanocatalyst are because of the excellent synergistic effect of the CuMoS2 flower and 2D mxene nanosheets, as evidenced by a superior (bio) sensing performance. The nanocomposite fabricated modified non-enzymatic biosensor was facilitating the analysis with wide linear ranges and nanomolar detection limit. The mxene@CuMoS2 modified sensor can also employed and promising its application towards the quantification of cancer biomarker in biological samples (urine and serum).
D-24: Hierarchical Porous Graphene Microsphere Ink for Printed Microsupercapacitors: Quanhong Chang1; Lei Huang1; 1Shanghai Normal University
Graphene ink, a promising ink formulation, is considered as a candidate for printing flexible solid-state supercapacitors. However, most of graphene materials are difficult to be applied as active ink used in printed MSCs because of their agglomerations due to the strong π–π interaction between the large basal planes.Herein, a kind of hierarchical porous graphene microsphere was rationally designed and assembled into printable ink for gravure printed MSCs. More importantly, these hierarchical porous graphene microspheres with a near spherical contour, which has ability to to support the axle and absorb shock from any direction without unfolding and even resist compression during the printing process. Meanwhile, depending on the hierarchical porous features of graphene microsphere, the specific physical and material properties of the inks, including solid loading, particle dispersion, viscosity, rheology behavior, etc were systematically investigated for realizing efficient production of high-performance flexible MSCs.
D-25: Printed Flexible Sensors Functionalized with TiO2 Nanowires for Room Temperature CO2 Gas Sensing: Lingyue Zhang1; Anming Hu1; Yongchao Yu1; 1University of Tennessee, Knoxville
In this work, we report a printed flexible silver electrode sensor coating with TiO2 nanowires works under room temperature. A silver electrode sensor was printed on polyimide using a VOLTERA commercial printer. TiO2 nanowire was deposited to silver electrodes by an electro-deposition method. The silver electrode sensor works at room temperature without additional heating requirements. The lowest carbon dioxide concentration detection limit for the sensor is 78 ppm. In addition, the response time is around 60s. This indicates the significant progress compared to conventional metal oxides CO2 sensors where a high working temperature (around 250-450°C) is usually required.
D-26: Processing of Bistable Composites with Embedded Mechano-electrical Transduction for Filtered Mechanosensing: Hortense Le Ferrand1; 1Nanyang Technological University
Mechanosensing is a key property for adaptable and smart structures. To translate this functionality to large and stiff structures, filtered sensing is required to decrease the amount of data sensed locally and select the relevant level of input stress. Filtered sensing using mechanical displacement is one strategy used in Nature to cope with large sets of stimuli. Here, we fabricate bistable elements that can passively filter mechanical inputs, translate them into electrical signals, and be reset using an external magnetic field. These multiple functionalities are achieved using hierarchically structured composites that can be arranged in large-area arrays and processed using additive manufacturing approaches. The filtering capability and fast passive response of the mechanosensors are experimentally demonstrated using simple electrical circuits and magnets and show potential for load-bearing structures that are able to sense, compute, communicate, and autonomously adapt.

D-27: Relation between Temperature Dependence of Gate Insulator and Magnetic Energy Effect of Thin Film Transistor without Channel Layer: Teresa Oh1; 1Cheongju University
Thin film transistors have one-way electrical characteristics. However, a recent study has been reported on thin film transistors that do not use channel materials. The source drain current is used through the gate insulation, and the amount of diffusion current is adjusted by the gate voltage giving magnetic energy to the source drain current. Geometry has barrier potential, so it has bi-directional properties because the direction of diffusion current (source drain current) works the opposite way according to the barrier potential. Because gate insulation film has a function of band gap of semiconductor, it is dependent on temperature, and resistance also has characteristics of negative resistance. Since resistance is a function of temperature, the temperature dependence of the gate insulation with negative resistance characteristics allows control of the heating phenomenon of LEDs. This study was researched the field effect transistor to apply semiconductor sensors reduce the heat generated by LEDs.
D-28: Wave Propagation in Optical Waveguides: Jonathan Martinez1; Samiha Hossain1; Jessy Nemati1; Nuggehalli Ravindra1; 1New Jersey Institute of Technology
A 2-D simulation of the wave propagation in optical waveguides is presented in this study. A variety of devices including all-polymer and semiconductor waveguides for short range and long range applications are considered. Various geometries of the optical waveguides are examined and compared in the simulation. Material choices and recommendations are investigated. A summary of 3-D printed optical waveguides and their performance is evaluated.
