Effect of Heating of Charge Carriers and Phonons on The Contact Resistance of Rectifying Metal-Semiconductor Structures

open access: yesEast European Journal of Physics
The dependence of the temperature of charge carriers and phonons on the contact resistance of the Schottky diode is calculated. It is shown that the increase in contact resistance depends on the current passing through the diode, the surface and volume ...

Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites

open access: yesAdvanced Functional Materials, EarlyView.
A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...

Pengaruh Jumlah Cascade dan Input Daya terhadap Temperatur Thermoelectric Cooling Box Portable [PDF]

open access: yes, 2014
Thermoelectric cooling is heat pump based on peltier effect. The peltier effect occurs when two metals or semi-conductors of different materials are connected and energized that there will be a difference in temperature.

Microscopic Theory of Magnon-Drag Thermoelectric Transport in Ferromagnetic Metals

open access: yes, 2012
A theoretical study of the magnon-drag Peltier and Seebeck effects in ferromagnetic metals is presented. A magnon heat current is described perturbatively from the microscopic viewpoint with respect to electron--magnon interactions and the electric field.

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Numerical modeling of the thermoelectric cooler with a complementary equation for heat circulation in air gaps

open access: yesOpen Physics, 2017
In this paper, a numerical model is developed by combining thermodynamics with heat transfer theory. Taking inner and external multi-irreversibility into account, it is with a complementary equation for heat circulation in air gaps of a steady cooling ...

SiO2‐CaOCME/Poly(Tetrahydrofuran)/Poly(Caprolactone) 3D‐Printed Scaffolds Drive Human‐Bone Marrow Stromal Cell Osteogenic Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...
