A comprehensive review on microchannel heat sinks for electronics cooling

International Journal of Extreme Manufacturing
The heat generation of electronic devices is increasing dramatically, which causes a serious bottleneck in the thermal management of electronics, and overheating will result in performance deterioration and even device damage.

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

Advanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Pressure-drop Reduction and Heat-transfer Deterioration of Slush Nitrogen in Square Pipe flow

, 2015
Pressure drop and heat transfer tests were carried out using slush nitrogen flowing in a horizontal square pipe at flow velocity between 1.0 and 4.9 m/s, with a mass solid fraction between 6 and 26wt.%, and with heat fluxes of 0, 10 and 20kW/m2. Pressure

An investigation on heat transfer deterioration in a tube using supercritical CO2 [PDF]

Supercritical CO2 (sCO2) can be employed as a working fluid in sCO2 power cycle. Supercritical fluids enhance thermal efficiency and enables compact system designs due to their favorable thermophysical properties. However, the intersection of sCO2 thermophysical properties with the two-phase-like regime leads to a pseudo-boiling phenomenon (PBP ...

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.
