Investigation on a complex type of magnetic refrigerants for the Ericsson magnetic refrigeration.

open access: yesTEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1986
A complex type of magnetic refrigerant for the Ericsson cycle has been investigated. For the magnetic refrigerant in the temperature range above -15K we have to use the ferromagnetic material, which has the internal magnetic field to arrange its spin system as far as using a magnetic field of -6T, because of increasing of the thermal excitation energy ...

Permanent magnet array for the magnetic refrigerator [PDF]

open access: yesJournal of Applied Physics, 2002
Recent research into the development of magnetic refrigeration (MR) operating at room temperature has shown that it can provide a reliable, energy-efficient cooling system. To enhance the cooling power of the magnetic refrigerator, it is required to use a magnetic refrigerant material with large magnetocaloric effect (MCE) at the appropriate ...

Quantum magnetometry using two-stroke thermal machines

open access: yesNew Journal of Physics, 2020
The precise estimation of small parameters is a challenging problem in quantum metrology. Here, we introduce a protocol for accurately measuring weak magnetic fields using a two-level magnetometer, which is coupled to two (hot and cold) thermal baths and

Effect of Minor Co Substitution for Fe on the Formability and Magnetic and Magnetocaloric Properties of the Amorphous Fe88Ce7B5 Alloy

open access: yesMetals, 2022
A small amount of Co was added to the Fe88Ce7B5 glass forming alloy for the possibility of improving its glass formability and magnetocaloric effect. The Curie temperature of the amorphous Fe88-xCe7B5Cox (x = 0, 1, 2, 3) ribbons increases linearly with ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Calculation of the Optimal Magnetic Duty Cycle for a Graded Coaxial Magnet of a Rotary Type Magnetic Refrigerator

open access: yesEnergies
In the design of a rotary-type magnetic refrigerator, a high field of a coaxial magnet is desired. Typically, a high-field design can be achieved with a small duty cycle, which might not be optimized from the viewpoint of the thermal hydraulics of a ...
