Eddy intrustion of hot plasma into the polar cap and formation of polar-cap arcs [PDF]

open access: yes
Under the simple postulate that multiple large scale detachable magnetospheric convection eddies can exist in the vicinity of the convection reversal boundary and in the polar cap, by Kelvin-Helmholtz instability or otherwise, it is shown that a number ...

Thermal Resistance of 1D Micron‐Wide Interface Under External Force Modulation

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel TET‐based technique is developed to characterize the interfacial thermal resistance at the microscale. The interfacial thermal resistance is measured at ≈1200–1400 mK/W for natural contact. Externally applied force reduces the thermal resistance dramatically down to ≈125 mK/W.

Thermal modeling of phase change solidification in thermal control devices including natural convection effects [PDF]

open access: yes
Natural convection effects in phase change thermal control devices were studied. A mathematical model was developed to evaluate natural convection effects in a phase change test cell undergoing solidification.

Ultrasonic Spray Pyrolysis of Functional Zn─Sn─O Matrix Semiconductors: Stoichiometric Design for Enhanced Acetone Selectivity in VOC Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
Zn–Sn–O thin films synthesized via ultrasonic spray pyrolysis reveal tunable phase evolution and enhanced acetone selectivity. Integrating DFT insights with machine learning predictions uncovers the role of stoichiometric control and oxygen vacancies in VOC sensing.

Manipulation of Convection Using Infrared Light Emitted from Human Hands

open access: yesAdvanced Science
Control of convection plays an important role in heat transfer regulation, bio/chemical sensing, phase separation, etc. Current convection controlling systems generally depend on engineered energy sources to drive and manipulate the convection, which ...
