Exploratory Study on Carbon Dioxide Blends With Low‐GWP Working Fluids for Medium and High‐Temperature Heat Pumps Under Step Pressure

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates binary zeotropic mixtures of R744 (CO₂) blended with eco‐friendly refrigerants for medium‐high temperature heat pumps, comparing them with conventional R744/R134a systems. All mixtures meet 60–80 K temperature lift requirements under low‐temperature conditions. A genetic algorithm optimized system parameters using fixed

Bioconvection Darcy–Forchheimer Flow of Ree‐Eyring Nanofluid Over a Riga Plate With Arrhenius Activation Energy and Viscous Dissipation

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work examines the intricate interactions of heat radiation, viscous dissipation, the Cattaneo–Christov thermal model, gyrotactic microorganisms, Arrhenius activation energy, and Darcy–Forchheimer flow affecting Ree‐Eyring nanofluid behavior across a Riga plate.

Magnetron Sputtering Synthesis of La‐Doped BiFeO3 Thin Films and Enhanced Exchange Bias in CoFeB/Bi1‐xLaxFeO3 Heterostructures

open access: yesAdvanced Physics Research, EarlyView.
This study explores the epitaxial growth of high‐quality La‐doped BiFeO3 (BLFO) thin films at 550 °C using magnetron sputtering. The films exhibit good ferroelectric properties and low leakage current. A BLFO/CoFeB heterostructure is constructed, achieving an exchange bias field exceeding the coercive field at room temperature.

Myeloid p38 activation maintains macrophage–liver crosstalk and BAT thermogenesis through IL‐12–FGF21 axis

open access: yesHepatology, EarlyView., 2022
Physiological activation of myeloid p38 controls macrophage IL‐12 production and crosstalk to the liver by modulating hepatic FGF21, and subsequently, brown adipose tissue thermogenesis during obesity Abstract Obesity features excessive fat accumulation in several body tissues and induces a state of chronic low‐grade inflammation that contributes to ...

Symmetry Control of Mutually Thermoelectric Conversion in Rutile RuO2

open access: yesAdvanced Physics Research, EarlyView.
We demonstrate that crystal symmetry can efficiently modulate mutual thermoelectric conversion. Longitudinal electric‐to‐heat conversion via the anisotropic crystal Peltier effect is observed in a RuO2 single layer without forming P–N junctions, and its dependence on crystal orientation is revealed by lock‐in thermography. Reciprocally, the anisotropic

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

open access: yesThe Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.
