Micromechanics of Wedge and Cone Indentation of Metallic Specimens with Subsurface Voids
Near-surface voids and pores occur in metal parts manufactured by processes as diverse as casting, powder metallurgy, and additive manufacturing. These pores range in size from a few microns to a few mm, depending on the ... -
Platinum overlayers characterization and fabrication via self-terminating electrodeposition
Hydrogen is considered a promising alternative fuel for the future. However, despite its perception as a “zero-carbon” energy carrier, fossil fuels remain the primary feedstocks for hydrogen production, involving significant ... -
Interfacial oscillations and atomization of liquid jets from non-circular orifices
Understanding the flow behaviour of liquid jets discharging from orifices is essential for several applications such as fuel spraying, ink-jet printing, aerosol devices in pharmaceutical industries, micro-machined fuel ... -
Paper-Based Point-of-Care Diagnostic Tools: Electrokinetic Nucleic Acid Extraction and Saliva-Based Glucose Detection for Diabetes Monitoring
Currently, we face a global challenge posed by the dual burden of chronic diseases such as diabetes and infectious diseases such as tuberculosis (TB). Low-and middle-income countries are disproportionately overburdened by ... -
Low–Speed Impact Mechanics and Fragmentation of Wooden Panels: Characterization of Indian Woods
Low–speed impact (LSI) of brittle structural panels by rigid bodies causes significant damage, evident in familiar scenarios like the breaking of monolithic and laminated glass panes due to stone pelting, punching a hole ... -
A geochemical and Ca, Sr, Nd isotopic study of the mantle: case studies of Kimberlites, Ophiolites, Abyssal Peridotites, and Layered Igneous Complexes
The Earth’s mantle constitutes 67% of its mass and despite mantle convection, it is geochemically and isotopically heterogeneous as evident from the compositions of mantle derived basaltic melts. It is a dynamic system ... -
Advancements in Nucleic Acid Lateral Flow Assay
In recent decades, the demand for rapid and precise nucleic acid amplification tests (NAATs) has grown significantly, driven by the need to address pandemics like COVID-19 and diagnose infectious diseases such as ... -
An investigation into the axial dipole field and mantle-induced heterogeneity in Earth
The Earth’s axial dipole field is generated by dynamo action in the planet’s outer core. It is understood from observations that the convection in the outer core is influenced by the lateral heterogeneity in the overlying ... -
Design and Performance Analyses of Osculating Cone Waveriders
Modern mission requirements for long-range maneuverable hypersonic vehicles for space, military, and transportation applications necessitate vehicle design innovations. The primary challenges that a hypersonic vehicle ... -
Evaluation Frameworks for Informed Multi-Site Multi-Variate Hydrological Assessment
The process of choosing a suitable hydrological model, calibrating it, and evaluating its performance poses intricate challenges for a modeler. The process of model selection is frequently influenced by the modeller's ... -
Novel Microfluidic Tools for Multiplex Colorimetric Detection of Analytes and Point Mutation Detection in Infectious Pathogens
Recently, the need for affordable point-of-care tests has grown exponentially. An ideal point of care (POC) test or device should satisfy the WHO-endorsed ASSURED criteria, meaning that the test/device should be accessible, ... -
Extratropical Influence on the Sub-seasonal Rainfall Deficit in Indian Summer Monsoon
The variability of Indian monsoon on a range of timescales - seasonal to interannual to decadal - has been studied and characterised extensively over the past several decades. On the mechanistic front, the role ... -
Analysis of Fetal Heart Sound for Fetal Heart Rate Monitoring
Perinatal mortality is the number of stillbirths and deaths during the first seven days of life per 1000 live births. Most (98%) of this death occurs in low- and middle-income countries (LMIC) and is known as the 'silent' ... -
A Framework for Effectiveness-based Sustainability Assessment in Manufacturing – A Product Life Cycle Approach
In recent decades, various human health impacts and environmental concerns (e.g., microplastic pollution, chemical exposure, biodiversity loss) associated with manufacturing/product life cycles have surfaced, threatening ... -
Investigations of Sensors Based on New Molecular Architectonics: Synthesis, Fabrication and Application
Rapid industrialization and expansion of urban landscapes in large cities generate maximum polluting ingredients to the surrounding environment. While organic contaminants are naturally occurring, the increase in human ... -
Synthesis of Monodispersed Pdms Microspheres of Tunable Modulus Using Droplet Microfluidics and Study of the Rheology of Dense Suspensions of Rigid and Soft Particles in Shear Flow
We report the synthesis of monodispersed PDMS microspheres of tuneable modulus using a droplet-based microfluidics approach. Nevertheless, polymer microspheres can be used as a model representative particle to mimic the ... -
Vorticity and scalar transport in turbulent round jets with and without heating
The round turbulent jets are ubiquitous in both natural and engineered systems such as clouds, engine exhausts, chimney plumes, and respiratory flows. We aimed to understand the vorticity and scalar transport in turbulent ... -
Intense Rainfall Events over the West Coast of India
West coast of the Indian peninsula is one of the regions which receive very heavy rainfall during the summer monsoon season. Average June-September rainfall over the parts of coastal Karnataka, Konkan and Goa exceed 250 ... -
Effect of Electric Current Pulses on Pre-cracked Thin Metallic Conductors: From Crack Propagation to Healing of Cracks
Both scientifically and technologically, it is important to investigate the effects of electric current on the structural integrity of metallic components. As an electric current reverses its direction across a crack, ... -
Rheology of dense non-Brownian suspensions
Suspensions are ubiquitous in nature and industry, ranging from magma, blood, and mud to cement, paint, and molten chocolate. Despite the Newtonian nature of the suspending fluid and the expectation of linearity in the ...
