Session 1 (10:00 AM -11:30 AM)

Title: Functional Materials for Defence Application

Dr. Anuj Shukla
Scientist E, Defense Laboratory, Jodhpur, Rajasthan, India.

Read Abstract

DRDO's impetus for exploring functional materials is primarily for enhanced lethality or increased survivability of military objects. Functional materials are materials that have one or more properties that can be utilized in a controlled fashion by external stimuli and therefore applied in a broad range of applications. Functional materials are found in all classes of materials: ceramics, metals polymers, organic molecules, nanomaterials and metamaterials. In this lecture, two different classes of functional materials: (i) nanomaterials such as iron oxide nanoparticles, core-shell nano alloy, carbon nanoballs, graphene and their defense application; (ii) metamaterials as absorbers, metamaterials in form of quick response (QR) code, which can carry information such as texts/image, metamaterials for health monitoring of polymer composites will be presented and discussed.

Session 3 (02:00 PM - 03:30 PM)

Title: Racetrack Memory Devices: Trapping and Injecting Single Domain Walls in Magnetic Wire

Dr. G. A. Basheed
Senior Scientist, National Physical Laboratory (NPL), New Dehli, India

Read Abstract

A single domain wall (DW) moves at linearly increasing velocity under an increasing homogeneous drive magnetic field. Present experiments show that the DW is braked and finally trapped at a given position when an additional antiparallel local magnetic field is applied. That position and its velocity are further controlled by suitable tuning of the local field. In turn, the parallel local field of small amplitude does not significantly affect the effective wall speed at long distance, although it generates tail-to-tail and head-to-head pairs of walls moving along opposite directions when that field is strong enough.

Title: Learning About Materials on the Nanoscale with Scanning Probe Microscopes

Prof. Maria Teressa Cuberes
Universidad de Castilla-La Mancha; Almadén; Spain

Read Abstract

Scanning Probe Microscopy (SPM) provide invaluable tools for the characterization and manipulation of materials on the nanoscale. In this Seminar I will introduce the basics of these techniques and illustrate some SPM-based procedures which I have contributed myself to develop along my scientific career. In particular, I will discuss the technique of Ballistic Electron Emission Microscopy (BEEM), and its possibilities for the characterization of the electronic response at semiconductor interfaces [1], and other possible applications. In addition, I will share several examples of the use of Scanning Probe Microscopy for the manipulation of individual molecules, and how to learn about materials self-assembling from this kind of experiments. [2] Eventually, I will introduce a the techniques of Atomic Force Microscopy with ultrasound excitation, and their application to study of nanoscale dynamic elastic, viscoelastic and adhesive properties on both hard and soft samples, and to provide subsurface information[3].

Session 3 (@ 2:30 pm)

Title: X-ray Non-destructive testing of materials and composites

Dr. Anja Waske
BAM Federal Institute for Materials Research and Testing, Berlin, Germany

Read Abstract

Using magnetic materials for energy conversion as an example, this lecture shows how X-ray tomography investigations can contribute to structure elucidation in composites and solid samples. The components are tested non-destructively in order to characterize cracks, pores and other defects and their influence on the functional properties three-dimensionally and in good time in the life cycle of the material. If one combines microtomography with other methods of magnetic material characterization, unique statements about the structure and the functional properties are possible.

Session 4 (@ 4:00 pm)

Title: Spark Plasma Texturing: a technology development for lead free pioezoelectrics

Prof.Paula M. Vilarinho
University of AveiroPortugal

Read Abstract

This talk addresses the sintering of undoped lead free piezoelectric (K1-xNax)NbO3 (KNN) ceramics by Spark Plasma Texturing (SPT) and compares their properties with equivalent ceramics prepared by Spark Plasma Sintering (SPS). I will describe the interplay between materials structure, microstructure, electrical conductivity, and non-linear dielectric properties for SPT KNN and the implications of these relations for enhancing electrical properties. Functional oxides, which include piezoelectric ceramics, are used in a wide variety of applications, from industrial machinery to compact electronic equipment and tools. Moreover, the Internet of Things is becoming a commodity, thus increasing the need for sensors and actuators. Consequently, it is expected that the overall market for piezoelectric devices will reach $31.33 billion by 2022. KNN is one of the most promising lead-free piezoelectric system to replace lead based piezoelectrics, mainly due to its high Curie temperature. Dense KNN ceramics require relatively high sintering temperatures, not compatible with the high vapour pressure of alkaline elements and thus alternative processing techniques are required. In this work we exploited the use of one derivative method of SPS that is Spark Plasma Texturing (SPT) defined as an edge-free SPS. We conclude that d33 (108 pC N-1), g33 (21.2×10⁻³ Vm N-1), Pr (19.7 μC cm-²) and Ec (11.9 kV cm-1) are significantly improved in undoped KNN ceramics processed, SPT. SPT KNN ceramics have a more homogeneous electrical microstructure with small grain size and narrow grain size distribution. SPT, as with hot-forging, results in neck destruction, particle rearrangement, and destruction of agglomerates improving the density and limiting grain coarsening, affecting point defects creation / distribution, giving rise to a rather homogeneous defect distribution. Consequently, SPT KNN ceramics grain cores and shells have similar resistance and capacitance behaviours. We hypothesise that, the electrical homogeneity of SPT KNN ceramics may along with the smaller grain size and higher density increase electric breakdown strength (EBDS) (of high relevance for industrial applications). In addition, the resultant compressively stressed lattice enhances the dielectric and piezoelectric performance.
