Investigating Membrane Dynamics And Oligomerization Of Pore-forming Toxins Using Single-molecule Fluorescence Techniques
The biological membrane is a thin fluidic matrix composed of a lipid bilayer that forms the primary cellular barrier against the extracellular environment. The high-density of embedded proteins and glycosylated molecules ... -
Dynamics of river plumes in the Bay of Bengal
The Bay of Bengal (BoB) receives a large amount of freshwater through runoff from sev- eral rivers along its border. This large freshwater gain has severe implications on the dynamics and thermodynamics of the BoB as ... -
Quasi-Static and Implicit-Dynamic Finite Element Solution of Large Deformation Elastic Adhesive Contacts Using a Volumetric Interaction Scheme
Adhesive forces, mediated by van der Waals’ and other interactions, dominate the contact response in the micron and sub-micron regimes. Understanding adhesion is especially important in biological systems (interaction of ... -
Studies on modeling the mechanics of slender elastic ribbons
Ribbons are slender structures characterized by three disparate geometric dimensions: length >> width >> thickness. Such a dimensional disparity enables ribbons to bend, buckle, twist and crease response to simple loading ... -
Molecular simulation of thermal conductivity in DNA and phonon dispersion in layered materials
Heat conduction plays a key role and is linked to the underneath lattice structure. The heat transfer in soft matter materials like DNA and polymers is seldom understood and is deeply linked to the geometry and functional ... -
Extraction of Creep Parameters from Indentation Creep Experiment: An Artificial Neural Network- Based Approach
Conventional methods for extracting creep properties require conducting several uniaxial tests at different loads, which consumes an intensive amount of material and time. Indentation may minimize the material volume ... -
Integrated Wastewater Management for Tank Restoration in Urban Fringe Areas
Urban fringe water bodies are often seriously affected by urban wastewater including partially treated sewage entering it and degrading it. Sustainability requirements necessitate that such wastewaters are treated and ... -
Atomization characteristics of alternative aviation biofuels, Jet A-1, and water from a hybrid airblast atomizer
Studies on the atomization of sustainable aviation fuels (SAF) from aircraft engine atomizers are essential to replace the present fossil type jet fuel to counter the rise in aviation-caused CO2 emissions in the atmosphere. ... -
Investigation of Thin Films for Frequency Selective Surface Based Radar Absorbing Structures
Modern day stealth aircraft uses microwave absorbers for absorption of incident Radar signals transmitted by rival aircraft. Recently, several attempts were made to fabricate radar absorbing structures (RAS) of various ... -
Physical insights into unstart dynamics of a hypersonic mixed compression intake
Hypersonic air-breathing cruise vehicles powered by supersonic combustion ramjet engines are the potential candidate for future space and defense applications. The air intake of the scramjet engine is a vital component ... -
An Application of Resonant Column along with Bender Elements Tests for Assessing Dynamic Properties and Liquefaction Potential of Sand
For determining the response of foundation soils subjected to different kinds of vibrations emerging from (i) an occurrence of an earthquake, (ii) movements of trains over railways tracks, (iii) running of vehicles over ... -
Investigation of thermoelectric properties of Sn-Te based alloys with microstructural studies
The basic concept of thermoelectricity is the conversion of dissipated heat into electricity with applications in the areas such as automobile engineering, refrigerating coolants, satellites, etc. The thermoelectric figure ... -
Mechanics of collective cell migration on substrates of different stiffness
Collective cell migration is characteristic in many physiological processes such as wound closure, morphogenesis, and cancer tumour metastasis. Experiments on cell monolayers demonstrated the formation of finger-like ... -
Droplet Isothermal Amplification For Nucleic Acid Quantification
Nucleic acid quantification (NAQ) is extensively employed for gene expression analysis, monitoring viral loads, detecting rare or dysfunctional cells, and assessing treatment regimes. The gold standard, quantitative ... -
On the development of Fe-containing high entropy alloys with improved strength at high temperatures
The emergence of new multicomponent high entropy alloys (HEA) has opened up new avenues for development of high performance materials for structural applications [1]. Among all of them, the precipitation strengthened HEAs ... -
Steady Sedimentation of Particles in Long Vertical Tube and Effect of End Boundary Conditions on Convective Motion
Sedimentation – settling of particles in a fluid- is observed in nature like rain droplets and dust particles in the atmosphere, and in a variety of industrial processes, like to clarify liquid as well as separate particles ... -
Evolution of recrystallization texture in face-centered cubic materials: Role of twin boundaries
The phenomenon of recrystallization and corresponding texture evolution in metallic systems has been studied for several decades yet not understood completely. The complexity of the problem arises due to its dependence on ... -
Stable isotope and biogeochemical study of arsenic contamination in shallow groundwater at seasonal time intervals from West Bengal (Nadia district)
Seasonal monitoring of groundwater is essential to ascertain safe water for the population and ecosystem for drinking, irrigation, domestic purposes and to keep track of groundwater quality with natural (climate change ... -
Electromechanical properties of PbTiO3 based piezoelectric ceramics and energy harvesting application of their flexible polymer composites
