CHARACTERIZATION OF SPECIFIC HEAT CAPACITY OF WATER-ALUMINUM OXIDE-BASED NANOFLUIDS

Rekayasa Mesin
Since the advent of nanofluids, engineers have expected major gains in thermal‐system efficiency. Yet a key property—specific heat capacity (Cp)—remains poorly understood, because Cp is not a single value but a spectrum governed by nanoparticle size ...

Dynamic Control of Synaptic Plasticity by Competing Ferroelectric and Trap‐Assisted Switching in IGZO Transistors with Al2O3/HfO2 Dielectrics

Advanced Functional Materials, EarlyView.
A frequency‐tunable ferroelectric synaptic transistor based on a buried‐gate InGaZnO channel and Al2O3/HfO2 dielectric stack exhibits linear and reversible weight updates using single‐polarity pulses. By switching between ferroelectric and trap‐assisted modes depending on input frequency, the device simplifies neuromorphic circuit design and achieves ...

Phase composition and transformations in magnetron-sputtered (Al,V)2O3 coatings

, 2019
Coatings of (Al1-xVx)2O3, with x ranging from 0 to 1, were deposited by pulsed DC reactive sputter deposition on Si(100) at a temperature of 550 {\deg}C. XRD showed three different crystal structures depending on V-metal fraction in the coating: {\alpha}-
