Transients generate memory and break hyperbolicity in stochastic enzymatic networks
Ashutosh Kumar, R. Adhikari, Arti Dua
The hyperbolic dependence of catalytic rate on substrate concentration is a classical result in enzyme kinetics, quantified by the celebrated Michaelis-Menten equation. The ubiquit…
Effective Thermal Conductivity of SrBiTiO-LaSrMnO Oxide composite: Role of Particle Size and Interface Thermal Resistance
Ashutosh Kumar, Artur Kosonowski, Piotr Wyzga1 +1
We present a novel approach to reduce the thermal conductivity () in thermoelectric composite materials using acoustic impedance mismatch and the Debye model. Also, the correlat…
Effect of interface resistance on thermoelectric properties in (1-x)LaSrCoMnO/(x)WC composite
Ashutosh Kumar, Krzysztof T. Wojciechowski
In this study, the synergistic effect of the particle size of the dispersed phase and the interface thermal resistance (R) between the phases on the phonon thermal conducti…

Artur Kosonowski, Ashutosh Kumar, Taras Parashchuk +2
Systematic experimental and theoretical research on the role of microstructure and interface thermal resistance on the thermal conductivity of the PbTe-CoSb3 bulk polycrystalline c…
Improved Thermoelectric Properties in (1-x)LaCoO3/(x)La0.7Sr0.3CoO3 Composite
Ashutosh Kumar, D. Sivaprahasam, Ajay D. Thakur
A high Seebeck coefficient (S), large electrical conductivity (σ), and reduced thermal conductivity (κ) are required to achieve a high figure-of-merit (zT) in an ideal thermoelectr…
Colossal Seebeck coefficient in Aurivillius Phase-Perovskite Oxide Composite
Ashutosh Kumar, D. Sivaprahasam, Ajay D. Thakur
We propose an inexpensive scalable approach for achieving extremely high values of Seebeck coefficient () by exploiting the natural superlattice structure in Aurivillius phase o…
