Abstract: In 2023, the National Academy of Engineering's Study Committee on Infusing Advanced Manufacturing into Undergraduate Engineering Education released its report on how engineering programs can better develop advanced manufacturing capabilities. The committee examined advanced manufacturing techniques in academia and industry, with a particular focus on the role that industries and governments can play by including undergraduate engineering students in their manufacturing initiatives. My talk will present highlights from this study, including a robust roadmap with specific guidance on ways to incorporate experiential learning emphasizing advanced manufacturing and strengthen ties between academia, industry, and government through mentoring and internship programs.

Abstract: Abstract_Prof_Joshi.pdf
Omniphobic surfaces, capable of repelling all types of liquids in addition to water are a great value addition in various applications ranging from self-cleaning, anti-icing , anti-biofouling, and hydrodynamic drag reduction to oil repellent coatings and oil/water separation. The texture design consists of a re-entrant topography that is vital to achieve oleophobicity as it enhances the stability of the composite liquid-solid-air interface. These surfaces are however prone to failure due to external pressure resulting in the loss of functionality.
Liquid Infused Surfaces (LIS), another class of super wettable surfaces, consist of a micro/nanotextured surface infused with a lubricating liquid to achieve liquid-repellent properties. The lubricant used is incompressible and immiscible with the external liquid, thereby creating a stable pressure phase. Thus, the presence of the infused lubricant within the cavities is integral to the success of LIS. In bulk flow, LIS, however, are susceptible to drainage failure caused by external shear imposed at the liquid-lubricant interface.
In this work, we combine the re-entrant topography (dovetail-shaped cavity) with a lubricating liquid and numerically evaluate the shear-flow-induced liquid-lubricant interface dynamics in a microchannel. The results show that when the lubricant is kept fixed, a less viscous external liquid aids in better lubricant retention. Due to the shear imparted, three stable and two failure meniscus shapes have been distinguished. Additionally, it was evident that, as the viscosity ratio was reduced, the effect of the cavity opening was no longer dependent on the flow rate.
Further, to understand the durability of LIS, we focus on the interface dynamics of LIS during transport for food packaging applications. We analyse the lubricant retention within the cavities when subjected to pure oscillations (zero net flow). The microchannel is excited longitudinally at f = 0.1 - 10 Hz for viscosity ratios (µr = 0.4 - 1.0 and µr = 1.8) for a dovetail cavity with a lubricant of two different densities. The results show a strong dependence on the viscosity of the external liquid and the density of the lubricant. A more viscous external liquid and a denser lubricant dampen the vibration effects and thereby exhibit a stable state with an intact meniscus.
Next, to demonstrate the performance of LIS with Newtonian and non-Newtonian liquids, 1D textures (ribs) are fabricated using a femtosecond laser and the drop movement is evaluated by varying the lubricant viscosity and tilt angle. The results show that increasing the tilt angle, the drop velocity increases whereas, the increase in lubricant viscosity enhances the drag and reduces the drop velocity. In addition, the surface is subjected external vibrations and shows a strong dependence on lubricant viscosity. A more viscous lubricant dampens the vibrations effects and does not deplete from the cavities, thus retaining the functionality of LIS.

Abstract: In the era of Space 2.0, exploring outer space involves traveling long durations, creating settlements in faraway locations, and exploiting partial gravity; these require extra-terrestrial manufacturing capability. Efforts are on-going in India to develop the ability to safely manufacture components, assemblies, and biologicals in outer space for use in space and back on Earth. The manufacturing technologies needed in space differ from the earth-based ones due to limited resources (space, energy, water, materials), micro/partial gravity, recycling, and limitations to track process inputs and outputs and to effectively recycle by-products. Acccess to various forms of micro-gravity platforms are important to simulate space environments and study several physical phenomena, and the know-how will influence the process technologies being developed. This talk will explore these exciting developments in the area of extra-terrestrial manufacturing (ExTeM).

Abstract : In soft and continuum robots, the body is made compliant unlike in industrial robots where the body is typically rigid. This makes them amenable for use in narrow constricted spaces for exploration, search and rescue, be in contact with humans, to grasp delicate and irregular objects and to manipulate them effectively. In this talk, we will present research done at the robotics lab in the areas of kinematic modelling, analysis and simulation of soft and continuum robots and experimental validation of the theories developed. The talk will focus on two kinds of actuators, namely pneumatic and cables, and present new results and approaches for continuum robots actuated by pneumatic artificial muscles and cables. The motion of an actuated endoscopic catheter and a three fingered cable driven robot which can grip and manipulate various objects are shown. The theory developed is also used to simulate and display the motion of a continuum robot in a pipe, in the GI tract and in a cluttered environment.

Abstract : With the growing geo political crisis and China plus one coupled with a young population, Indian manufacturing is likely to grow very steep in the coming decade from the current level of 17% of GDP to close to 30% of Indian GDP. This growth would translate to huge opportunities for MSMEs to contribute more significantly and contribute to the manufacturing growth story. Simultaneously, there is a huge transformation happening in the manufacturing with the rapid adoption of industry 4.0 across several sectors. To balance and achieve this growth, there is a greater necessity to improve the efficiency by rapidly skilling up on the appropriate technologies. Embracing the industry 4.0 Indian manufacturing will grow significantly and contribute to make India a manufacturing hub of the world in the next decade.

Abstract : Indian GDP is growing and is currently among the top 5 in the world. Targeted to reach the top 3 by 2030, the potential for growth is around 8 to 10 %. Manufacturing is the key to growth. With Atma Nirbar Bharat and production-linked incentive PLI (for localisation of newer areas like EV), let us look at the overall scenario. There is push-pull, "push" - from the younger population with a lot of keenness for new needs and requirements and sustainability goals "pull" - from the companies, Indian market conditions, competitiveness, and quality (zero defect). The drive towards competitiveness is skill up and reskilling of the workforce. The three groups of operators/supervisors, middle managers, and top management have different shares of roles of responsibility and authority. The top management focus is on breakthrough/innovation, operators on retainment, and middle management is on 30% of breakthrough and 70% on retainment. The drivers of skill enhancement is about going deeper (changes in EV, product, battery, cost; lightweighting - aluminium, titanium), integration of hydrogen, methanol etc. for cost competitiveness. Adaptation towards digital, operation research techniques - (linear and stochastic tools) for the right strategy is required. As the population is younger - each product is different N = 1. So, the speed of delivery should be combined with flexibility of facilities and agility for quicker response time. Though we talk about AI/ML, Digital, OR techniques - the basics should be made stronger and not forgotten. Traceability is the key for capturing data from factory environment and actions for improvement. The availability of sensors, data capturing, analysis & actions in various areas and improvement of productivity, quality, cost and sustainability are shared in this talk.
