Title of Plenary Speech
Predicting effective thermal conduction and mechanical behavior of porous structures

 

Abstract of Plenary Speech
Materials containing internal pores are ubiquitous in structural components and functional devices. Metamaterials and lattice structures, fabricated by additive technologies, also incorporate regular empty space into their design. Understanding how the geometic configuration of the pores affects the overall material properties calls for systematic analyses. In this presentationwe highlight our recent developments of numerical models to predict the effective thermal conductivity and mechanical behavior of porous structures, with attention devoted to various shapes (aspect ratios), sizes, and periodic spatial distributions of the existing voids. Starting with the simplest case with one pore per unit cell, we gradually increase the level of complexity of the geometric model. When the aspect ratio of the pores deviates from unity, anisotropy becomes important and the underlying geometry plays an increasing role in dictating the overall material behavior. The internal pores become embedded cracks in the limiting case, which can be analyzed using the same methodology. Insights gained from the theoretical consideration have direct implications in the design and performance evaluation of pore-containing structures.

Title of Plenary Speech
Stents and Additive Manufacturing

 

Abstract of Plenary Speech
Medical practitioners have been using stents to overcome the constriction of arteries or to maintain certain lumens in our body. Stents themselves have been around for more than 40 years and have seen significant developments in their fabrication techniques. Moving from metal based stents, currently, polymers have also been used to produce stents. After bare metal stents, drug eluting stents and bioresorbable stents are also being implanted. Fabrication techniques have also been improved to produce better and cost effective stents. Currently, efforts have been expanded to use 3D printing as one of the alternatives in stents fabrications. Reports have shown that additive manufacturing have been used to attempt to fabricate cardiovascular stents but issues related to their reduced qualities were mentioned. This talk will compare two products of Direct Metal Laser Sintering for tracheal stents. The final products show that, with improvement in the design, better and stronger stents can be produced. However, other qualities of the stents need more investigation.

Title of Keynote Speech
Design of antioxidant self-assembled nanomedicine for oral drug delivery system

Abstract of Keynote Speech
Since oral administration is preferable for patients to improve their quality of life, it is very essential if drugs, which are only approved by injection, can be extended to oral medication. This is the reason that many reports have been published using nanoparticle-assisted oral drug delivery system (DDS); however, they have remained many challenges. In order to overcome the drawbacks of oral DDS, we designed an original silica-containing antioxidant nanocarrier (siRNP), which was prepared by the self-assembly of an amphiphilic block copolymer (PEG-b-siPMNT) possessing a poly(ethylene glycol) (PEG) shell as a hydrophilic segment and ROS-scavenging nitroxide radical and silica moieties in the hydrophobic core. There are several points to improve the effectiveness of oral DDS by siRNP as follows: i) Polymer micelle-based design: Since the hydrophobic segment of the amphiphilic block copolymer is composed of PEG, the densely packed brushes on the nanoparticle surface improve its dispersion even under the harsh GI tract conditions, preventing nanoparticle aggregation and keeping its small sizes, and improving accumulation in the intestinal mucosa. we have previously confirmed that the core-shell type polymer micelles improved the accumulation tendency in the intestinal mucosa by almost two orders of magnitude than that of commercially available polystyrene nanoparticles although they are initially the same size before the oral administration; ii) Silica installation in the core of RNP: Several nanometer-sized silica in the core of RNP increased the stability of the self-assembling polymer micelles (RNP) by the crosslinking of the block copolymer chain to each other, which prevents disintegration and/or coagulation of the nanoparticle and further improve accumulation in the intestinal mucosa; iii) Another effect of the silica crosslinking: The installation of silica in the core of RNP also improves the drug loading capacity by drug adsorption on the porous silica surface in the core, preventing the leakage of the drug from the carrier; iv) Installation of nitroxide radicals in the core of nanocarrier: The installation of nitroxide radicals in the core via the covalent conjugation increases antioxidant character of nanocarrier. The covalent linkage prevents leakage of the antioxidants and ensures its safety. Recently, we have investigated that siRNP significantly improved the bioavailability of conventional hydrophobic drugs. The orally administered drug@siRNP effectively suppressed the intestinal inflammation and cancer, liver fibrosis, and minimized the adverse effects of conventional drugs.

Title of Invited Talk
AI-Enhanced Nanosensors for Environmental Monitoring, Smart Home and Metaverse

Abstract of Invited Talk
In the Internet of Things (IoT) era, various devices (e.g., sensors, actuators, energy harvesters, etc.) and systems have been developed toward the realization of self-sustained IoT sensor nodes for smart homes/ buildings and environmental. The surface-enhanced infrared absorption (SEIRA) spectroscopy provides lattice and molecular vibrational fingerprint information which is directly linked to the molecular constituents, chemical bonds, and configuration. The nanosensors using Infrared (IR) plasmonic nanoantennas (PNAs) are powerful tools to identify molecules by the IR fingerprint absorption from plasmon-molecules interaction based on the SEIRA spectroscopy technology. Secondly, the nanophotonic waveguides that implement long optical pathlengths on silicon photonics chips have been investigated as promising gas sensors for the weak interactions with gas molecules in the infrared absorption (SEIRA) spectroscopy as well. By leveraging large longitudinal electric field discontinuity at periodic high-index-contrast interfaces in subwavelength grating metamaterial and its unique features in refractive index engineering, a nanophotonic waveguide sensor achieves acetone absorption spectroscopy at 7.33 μm, showing a detection limit of 2.5 ppm with a waveguide length of only 10 mm. The artificial intelligence (AI) technologies push forward the development of diversified smart nanosensors in order to realize the advanced artificial intelligence of things (AIoT) technology. Furthermore, the recent advances in the combination of AIOT based nanosensors in the human machine interfaces (HMI) and innovative micro-haptic technology will provide the excellent immersive user experience in the future metaverse.

Quantum secure communication: Activities and prospects

Abstract of Invited Talk

Quantum optics offers a framework to test fundamental aspects of quantum mechanics such as coherence, entanglement, and non-classical properties of light. More recently, it has led to the development of quantum technologies which aim to harness quantum principles for promising applications in computing, communication and precision metrology. This area has evolved significantly in recent years, and this year Physics Nobel prize has also been awarded for ground breaking experiments in these domains. Quantum key distribution (QKD) is a method of quantum cryptography, which has become a new generation security solution and does not rely on the computation assumptions of problems presumed difficult. This talk will begin with several key aspects of fibre and free-space quantum secure communication and would further highlight efforts being made by our group at IIT Delhi for both research and development in these areas. One of our studies also focuses for exploring the effects of partial coherence on spatial profile, polarization entanglement and squeezing features of biphotons. These non-classical photon beams having partially spatially coherent features can be more robust against atmospheric losses and turbulence compared to their fully coherent counterparts, offering a way to achieve higher key rates in quantum communication applications. Some implementations of QKD in lab scale and in field would also be discussed. The prospects of photonic quantum technologies would also be highlighted emphasising on field deployable devices for QKD and hybrid quantum networks for future quantum internet.

All-weather solar cell incorporating long persistent phosphors and carbon

Abstract of Invited Talk

Solar energy has gained much research interest due to its attractive feature and low fabrication cost. It also does not produce CO2 emission during the energy conversion. However, the main issue of solar energy is its inability to generate electricity when there's no light irradiation. Therefore, development of all-weather solar cell is proposed. The device is designed to generate electricity during day and nighttime. In this work, a simple methodology to fabricate all-weather dye-sensitized solar cell (DSSC) is presented. The electrode of the DSSC was doped with green-emitting long persistent phosphors (LPP) and carbon quantum dots (CQD) in order to provide the photoenergy conversion functionality under dark condition. The fabricated DSSC was able produce a power conversion efficiency of 3.22% under dark along with consistent power output for at least 30 minutes. The light emission under dark is made possible by the LPP where the absorbed light during light irradiation is released as green photo fluorescence when the light source is removed. This work represents a step forward for the improvement of versatile DSSC.

Design the compliant tristable mechanism with two different bistable mechanisms

Abstract of Invited Talk

This study presents a new method to design a compliant mechanism with three distinct motion positions. The connection of a frame mass constructs the mechanism, and two bistable mechanisms have two stable positions. Each of the two stable mechanisms worked based on the tension and compression of the flexible element. The combination of the two bistable mechanisms with different behavior accurately predicts the tristable mechanism's characteristics. The finite element method is employed to analyze the compliant bistable mechanisms and tristable mechanisms. The results show the maximum forces of the tristable mechanism close to the maximum force of the bistable mechanism and easily predict the stable position of the tristable mechanism based on the stable position of each bistable mechanism. The frame mass's stiffness causes the maximum force error. This method is investigated against several tristable mechanism designs to demonstrate its effectiveness.

Calcium Carbonate from Chicken Eggshells as Filler in Composite Nafion Membrane for Direct Ethanol Fuel Cell: A Molecular Dynamics Studied

Abstract of Invited Talk 
The problem of ethanol cross-over from anode to cathode reduces the overall performance in the Direct Ethanol Fuel Cell (DEFC). Therefore fillers are used to reduce the problem of ethanol cross-over. Therefore, this study developed calcium carbonate (CaCO3) from Chicken Eggshells as Filler in Nafion Membrane Composite for Direct Ethanol Fuel cells. Three clusters of CaCO3 are formed as filler in the Nafion membrane, namely as (CaCO3)2, (CaCO3)3 and (CaCO3)4 and conducted using the Molecular Dynamics method to determine properties of the composite membrane, namely ion conductivity, ethanol permeability and selectivity. Three main factors influencing the three composite membranes were tested in this study: cluster size of CaCO3, filler loading in wt% and ethanol concentration. The presence of filler has reduced ethanol permeability in DEFC application compared to the Nafion membrane. Selectivity is used to balance the properties of ion conductivity, and ethanol permeability as these two properties are very important to improve the overall performance of DEFC. A3%-1M, B3%-1M and C3%-1M have lower ion conductivity than the Nafion membrane, but all three composite membranes have higher selectivity than the Nafion membrane. All three composite membranes are suitable for use at low ethanol concentrations. Composite membrane C ((CaCO3)4) is required to restrict ethanol permeability at a high ethanol concentration of 5 M. Large structure size in cluster (CaCO3)3 can reduce ethanol permeability but requires loading (CaCO3)3 by 5wt%. ANOVA analysis showed significant values for the three responses of ion conductivity, ethanol permeability and selectivity.
