Laser Welding Nanowires for Smart Sensing: Yongchao Yu1; Lingyue Zhang1; Pooran Joshi2; Anming Hu1; 1University of Tennessee; 2Oak Ridge National laboratory
We repot a clean room free laser induced nanowires welding process for a multi targets detection sensing system. Nanowires have unique structural properties comparing with high dimensional materials such as films and bulks. Especially, single nanowire is attractive as a basic component for nanoelectronics and ultrasensitive devices. In this works, two different types of laser were used for studying the differences in effect on nanowire after laser irradiation. Based on different working properties, a 523 nm continuous wave laser and a 1030 nm femtosecond pulse laser were selected for comparison studies. Based on experimental results, laser induce nanowire welding process was developed. After welding, the contact resistance between nanowires and substrate electrodes was reduced significantly. Also, with an ultra-fast laser, a high accuracy processing of oxidizable metal was achieved under air condition. This method also applied to a multi targets detection smart sensing system through pattern recognition and machine learning.

Large Scale Laser Direct Manufacturing of Functional Structures for Electro–optical Applications: Gary Cheng1; 1Purdue University
Our recent explorations into the integration and manipulation of nanoengineered materials and their composites in functional components have enabled new opportunities and challenges in large scale manufacturing of materials system for energy, automobile, aerospace, biomedical, electronics and photonics applications. This talk will discuss several lasers based manufacturing techniques, e.g. to fabricate electro-optics, energy storage devices, and biosensors and based on integration of 0D-2D nanomaterials. The presentation will start to discuss the fundamentals of several unique nanomanufacturing techniques developed in our group, including laser shock induced nanoshaping, laser shock wraping of 2D graphene with 0D nanoparticles, laser crystallization of solution based 0D nanomaterials, and laser plasmonics welding of 2D nanowires, and self-welding of 2D and 1D nanomaterials, and layered manufacturing of nanomaterials. These manufacturing process not only significantly reduce the manufacturing time but also improve the property of devices. The applications of these manufacturing process will be discussed in transparent conductive layers, nano-battery, supercapacitors, 3d nanoengineered plasmonics and graphene based biosensors.

Highly Sensitive and Selective Room Temperature Ammonia Sensor: Shivani Sharma1; Rajan Saini2; Sandeep Sharma3; 1Guru Nanak Dev University; 2Rutgers The State University of New Jersey; 3Guru Nanak Dev University, Punjab
Recently two-dimensional materials such as WS2 and MoS2 have attracted great attention due to their fascinating physical properties. Due to their 2-D character these materials possess high surface-to-volume ratio, important for sensor devices. The optical and electronics properties of these layered materials have been extensively explored, but gas sensing behaviour of these materials still remains unexplored. In nanostructure form, WS2 behaves like a p-type material and a strong interaction is expected with electron donor species such as ammonia. In view of these aspects, we have investigated the sensing response of WS2 based sensors to ammonia, ethanol, acetone, benzene etc. The sensor is highly sensitive and selective to ammonia at room temperature and has detection limit as low as 5 ppm (sensing response 120 %), much below the prescribed occupation exposure limit of NH3 gas. Present work justifies the potential of 2-D nanostructures as high-performance gas sensors.

Microporous Metal-organic Framework and Polymer Sensing Layers for Energy Infrastructure Monitoring Applications: Paul Ohodnicki1; Ki-Joong Kim2; Jeffrey Culp2; Tao Hong2; 1National Energy Technology Laboratory (presently at University of Pittsburgh); 2National Energy Technology Laboratory
Increased needs exist for selective monitoring of key chemical species across the energy infrastructure including natural gas transmission and delivery (e.g. pipelines), grid asset health monitoring (e.g. transformers), and carbon storage and sequestration. Emergent low cost, distributed sensing platforms including optical fiber and passive wireless sensors are ideally suited for addressing this technological need but require engineered functional sensing layers that are tailored for analytes of interest. Microporous metal-organic framework and polymer-based sensing layers show promise for such applications due to a physisorption based sensing mechanism and high sorption capacity for gas species of interest (CO2, CH4, H2, etc.) which yields a combination of high sensitivity, selectivity, and reversibility when optimally integrated with sensor device platforms. This presentation will overview recent efforts focused on development of novel sensing layers based on both polymer and metal-organic framework materials as well as integration with both optical fiber and surface acoustic wave devices.

Site-selective Synthesis of Core-Shell Nanowires for Nanoelectronics Assembly and Soldering: Edward Fratto1; Jirui Wang1; Brendan Lucas1; Hongwei Sun1; Zhiyong Gu1; 1University of Massachusetts, Lowell
One-dimensional nanowire structures have the potential to enable sophisticated design and integration of functional electrical components for modern electronics and devices, such as nanoelectronics, sensors, or printed electronics. However, engineering of nanostructures has been limited by associated challenges of assembly and interconnection. This work presents a core/shell multi-segment nanowire structure which achieved macroscale interconnection via magnetically-assisted assembly and soldering. Au-Ni-Au nanowires were synthesized via electrodeposition in AAO template, with Ni acting as a magnetic vehicle for assembly. Au-selective deposition of Sn was achieved via establishment of a chemisorbed Ni-protective monolayer, followed by immersing the nanowires in aqueous solution for selective chemical reduction. Core-shell formation was confirmed by SEM/TEM and EDS. These “dumbbell” shaped core/shell nanowires were assembled tip-to-tip and soldered, establishing ohmic electrical and thermal interconnection. This work provides an effective and scalable method for site-specific nanowire functionalization while simultaneously addressing miniaturization-associated assembly and packaging issues in its desired applications.

3D Printed Magnetic Augmented Rotation System - Design, Fabrication & Performance: Navjot Panchi1; Jonathan Martinez1; Linus Garcia1; Tien See Chow2; Nuggehalli Ravindra1; 1New Jersey Institute of Technology; 2ETD Inc.
The Magnetic Augmented Rotation System (MARS) offers an alternate method for the transfer of torque that is usually accomplished between the habitually employed contacting gear systems. The utility of gear systems in environmental applications such as wind turbines, dams, electric vehicles, etc. will naturally require the use of more reliable alternatives than contacting gears, which offer near equal benefits as their deficiencies; A solution lies with MARS’ contactless gear system and its. Simulations of a concentric magnetic gear design are introduced while also being compared to a 3D-printed model. A comparison of multiple simulations of the contactless gear system is also shown as a procedure to select the fabricated 3D-model. An analysis of the simulation and 3D-printed gear’s results reflect the viable usage of the newMARS gear system in renewable energy applications.

Laser Scripted Graphene and Metal-nanostructures for Flexible Microwave Devices: Ruozhou Li1; Jing Yan1; Yuming Fang1; Ying Yu1; 1Nanjing University of Posts and Telecommunications
Flexible microwave devices are essential for new-concept wearable electronics, whereby graphene and metal nanostructures frequently serve as the basic materials. Laser-direct writing appears to represent a good alternative to traditional methods for the structuring and tuning of graphene and metal nanostructures. Utilizing laser reduction and sintering, we present fast, flexible and compatible printing methods to construct and tune the graphene and metal based nanostructures. By incorporating of “melting point depression” phenomenon and surface plasmon enhanced photothermal effect, we display that it is possible to tune the conductivities of nanostructures in several orders of magnitudes. Simulations are also conducted to reveal the interactions between the microwave and these microwave structures. Demonstrations of transmission lines, resistors capacitors, inductors and antennas with processing high frequency microwave signals are presented. These laser scripted flexible microwave devices are potential for microwave signal processing, communication and sensing applications.

Multi-scale Modeling Method of Laser Selective Melting: Ze-Chen Fang1; Zhi-Lin Wu1; Chen-Wu Wu2; 1Nanjing University of Science and Technology; 2Institute of Mechanics，Chinese Academy of Sciences
Theoretical model could be utilized to effectively predict the patterns of material temperature, thermal stress and their effects on mechanical properties of the parts formed by Laser Selective Melting or Sintering. A large quantity of existing macroscale model is reported based on continuum theories and aimed at quickly simulating the large scale average experimental results. However, micro-mechanism and systematic process optimization method are limited due to single analysis scale. In the present article, the multiscale method was proposed to analyze such complicated physical process. At microscale, the internal physical mechanism of the laser selective fusion TC4 powder, such as temperature field and phase transformation regular, are demonstrated by molecular dynamic analysis. At macroscale, the constitutive model is developed to describe the thermal elastoplastic stress-strain response as well as the solid phase transformation. At the same time, coupled with microscale analysis the main model under OPENFOAM constructs the whole multi-scale model through experimental verification and lays a foundation for the realization of closed-loop control of SLM process.
