Feasibility and safety of passive cooling in a cohort of asphyxiated newborn infants

open access: yesSwiss Medical Weekly, 2013
OBJECTIVE: Therapeutic hypothermia has become a standard neuroprotective treatment in term newborn infants following perinatal asphyxia. Active cooling with whole body surface or head cooling is complex, expensive and often associated with initial ...

Cooling of a Micro-mechanical Resonator by the Back-action of Lorentz Force

open access: yes, 2009
Using a semi-classical approach, we describe an on-chip cooling protocol for a micro-mechanical resonator by employing a superconducting flux qubit. A Lorentz force, generated by the passive back-action of the resonator's displacement, can cool down the ...

STEADY-STATE HEAT REJECTION RATES FOR A COAXIAL BOREHOLE HEAT EXCHANGER DURING PASSIVE AND ACTIVE COOLING DETERMINED WITH THE NOVEL STEP THERMAL RESPONSE TEST METHOD

open access: yesRudarsko-geološko-naftni Zbornik, 2018
At three locations in Zagreb, classical and extended thermal response test (TRT) was conducted on installed coaxial heat exchangers. With classic TR test, thermogeological properties of the ground and thermal resistance of the borehole were determined at

Cooling capacity evaluation of passive radiation cooling materials

open access: yesJournal of Physics: Conference Series, 2022
Abstract passive radiation cooling technology has aroused widespread interest and research enthusiasm because it can cool objects with zero energy consumption, and even cool to below the ambient temperature. At present, when evaluating the cooling performance of radiation cooling materials, in order to reduce the impact of air convection

Passive scalars, moving boundaries, and Newton's law of cooling

open access: yes, 2014
We study the evolution of passive scalars in both rigid and moving slab-like domains, in both horizontally periodic and infinite contexts. The scalar is required to satisfy Robin-type boundary conditions corresponding to Newton's law of cooling, which ...

High Thermoelectric Power Factor in Graphene/hBN Devices

open access: yes, 2016
Fast and controllable cooling at nanoscales requires a combination of highly efficient passive cooling and active cooling. While passive cooling in graphene-based devices is quite effective due to graphene's extraordinary heat-conduction, active cooling ...
