Miniature work-to-work converter engine powered by motor protein
Suraj Deshmukh, Sougata Guha, Basudha Roy +3
Designing a miniature microscale engine that can override the role of thermal fluctuations has remained elusive and is an important open challenge. Here we provide the design and t…
Direct and simultaneous measurement of the stiffness and internal friction of a single folded protein
Surya Pratap S Deopa, Shatruhan Singh Rajput, Aadarsh Kumar +1
The nanomechanical response of a folded single protein, the natural nanomachine responsible for myriad biological processes, provides insight into its function. The conformational…
Translational diffusion of a fluorescent tracer molecule in nanoconfined water
Shivprasad Patil, V. J. Ajith
Diffusion of tracer dye molecules in water confined to nanoscale is an important subject with a direct bearing on many technological applications. It is not yet clear however, if t…
Resistive switching in HfO2-x/La0.67Sr0.33MnO3 heterostructure: An intriguing case of low H-field susceptibility of an E-field controlled active interface
Vivek Antad, Parvez A. Shaikh, Abhijit Biswas +5
High-performance non-volatile resistive random access memories (ReRAM) and their small stimuli control are of immense interest for high-speed computation and big-data processing in…
Elasticity of single flexible polymer chains in good and poor solvents
Vikhyaat Ahlawat, Shatruhansingh Rajput, Shivprasad Patil
Force versus extension curves measure entropic elasticity of single polymer chain in force spectroscopy experiments. A Worm-like Chain model is used to describe force extension exp…
Validity of point-mass model in off-resonance dynamic atomic force microscopy
Shatruhan Singh Rajput, Surya Pratap S Deopa, V. J. Ajith +2
The quantitative measurement of viscoelasticity of nano-scaleentities is an important goal of nanotechnology research and there is considerable progress with advent of dynamic Atom…
A new method for measurement and quantification of tracer diffusion in nanoconfined liquids
V. J. Ajith, Shivprasad Patil
We report development of a novel instrument to measure tracer diffusion in water under nano-scale confinement. A direct optical access to the confinement region, where water is con…
Non-van der Waals honeycomb antiferromagnet SrRuO down to a few layers
Suvidyakumar Homkar, Bharat Chand, Shatruhan Singh Rajput +8
The current family of experimentally realized two-dimensional magnetic materials consist of 3 transition metals with very weak spin-orbit coupling. In contrast, we report a new…
Elastic response of poly(ethylene glycol) polymer chains studied using dynamic atomic force microscopy
Vikhyaat Ahlawat, Shatruhan Singh Rajput, Shivprasad Patil
Stretching response of polymer chains under external force is crucial in understanding polymer dynamics under equilibrium and non-equilibrium conditions. Here we measure the elasti…
The effect of boundary slippage and nonlinear rheological response on flow of nanoconfined water
Amandeep Sekhon, Ajith VJ, Shivprasad Patil
The flow of water confined to nanometer-sized pores is central to a wide range of subjects from biology to nanofluidic devices. Despite its importance, a clear picture about nanosc…
Excess area dependent scaling behavior of nano-sized membrane tethers
N. Ramakrishnan, Arpita Roychoudhury, David M. Eckmann +6
Thermal fluctuations in cell membranes manifest as an excess area () which governs a multitude of physical process at the sub-micron scale. We present a theoreti…
A new tuning fork-based instrument for oscillatory shear rheology of nano-confined liquids
Karan Kapoor, Vinod Kanawade, Vibham Shukla +1
We present a new method to measure rheological response of liquids confined to nano-scale which exhibit a considerable slow-down in dynamics compared to bulk liquids. The method re…
Direct evidence of photo-ionization causing luminescence "off" state in CdTe Quantum dots
A. V. R. Murthy, Padmashri Patil, Shouvik Datta +1
We present a direct experimental evidence of photo-ionized CdTe quantum dot core having luminescence "off" state at band-edge photo-excitation. We use the autocorrelation of fluore…
Dynamic Solidification in Nanoconfined Water Films
