Summary: This study investigates the impact of nanofluid concentration on the natural convective flow of magnetic fluid in a sinusoidal cavity with variable wavelengths. The results show that the heat transfer rate, kinetic energy, and entropy generation increase with decreasing volume concentrations of nanofluid, while they are negatively affected by the magnetic field. The study also reveals that the Hartmann number has a significant effect on fluid flow, thermal parameters, and entropy generation. Furthermore, the Rayleigh number plays a notable role in entropy generation, with higher values resulting in higher entropy generation. Grade: 7/10

Summary: The ISPH method is used to analyze the effects of a magnetic field on thermosolutal convection of solid particles spreading within a finned cavity. The simulations show that solid particles tend to move towards the upper part of the cavity and the fins on the upper wall play a role in adjusting the spread of the particles. The blending between solid and fluid particles is influenced by an increase in the Hartman parameter, while the Soret and Dufour numbers reduce the blending of solid particles within a nanofluid flow.

Summary: The microstructure of the Li7La3Zr2O12 (LLZO) garnet solid electrolyte plays a critical role in the performance of all-solid-state lithium-ion batteries. Second phases generated at the grain boundaries during high-temperature sintering have a significant impact on the properties of LLZO. However, the detailed structure of these second phases and their effect on physical properties have not been thoroughly studied. In this study, the crystal structures of Li-Al-O second phases in LLZO pellets were examined using transmission electron microscopy. Three different crystal structures were identified, and their structure-property relationship was explored. It was found that sintering aids with a higher Li/Al ratio promote the formation of Li-rich second phases, which enhances the ionic conductivity of LLZO.

Summary: Numerical simulations of brittle fracture using phase-field methods often face challenges in accurately modeling fully developed cracks due to the limitations of using low order elements for the phase-field. By combining a standard linear finite element discretization with a finite volume approximation of the phase-field evolution equation on the same mesh, looser mesh refinement restrictions can be achieved, resulting in significant reductions in computational costs.

Summary: This article examines the irreversibility of natural convection in water/copper nanofluids within a square enclosure. The study analyzes thermal entropy generation, frictional entropy generation, and total entropy generation by varying the Hartmann number, baffle thickness and length, and magnetic field angle. The numerical analysis is conducted using the Lattice Boltzmann method. Results show that increasing the Hartmann number reduces the velocity components and temperature gradient in the enclosure and decreases all types of entropy generation. Increasing the magnetic field angle enhances thermal and frictional entropy generation as well as total entropy generation, with the Bejan number initially decreasing and then increasing.

Summary: The study focuses on the influence of rheology on the initiation of thermal convection in a rotating nanofluid layer heated beneath with an alternating current electric field. Linear stability analysis is employed using stress-free bounding surfaces. The rheological behavior of the regular fluid is described by the Oldroyd model, while the Buongiorno model is used for nanofluids with considerations for thermophoresis and Brownian motion. Exact solutions of the eigen-value problem are obtained using the single term Galerkin technique, and the expressions of the thermal Rayleigh number for both stationary and oscillatory convection are presented graphically for different nanoparticle configurations.

Summary: This paper compares the hydrothermal performance of divergent and convergent walls in two-layer microchannels. The results show that divergent walls decrease the pumping power and average Nu number, but increase the thermal resistance and base temperatures. Conversely, convergent walls increase the pumping power and average Nu number, while decreasing the thermal resistance and base temperatures. The study also finds that microchannels with low TF values (more convergent) are more hydrothermally optimal compared to those with high TF values (more divergent). Furthermore, divergent microchannels generate lower frictional entropy and higher thermal entropy, while convergent microchannels produce higher frictional entropy.

Summary: This literature review explores the potentials of liquid micro-/mini-channels in reducing operating temperatures and achieving more uniform temperature distributions in batteries. It includes a classification and overview of battery thermal management methods, introduces different types of lithium-ion batteries and their pros and cons, and describes battery components in detail. The review summarizes studies on the performance of micro-/mini-channels for cooling rectangular and cylindrical batteries, with the key finding being that using a counterflow configuration leads to a relatively uniform temperature distribution and keeps the maximum temperature difference below 5 degrees C. The survey further reveals that proper channel paths and flow configurations can maintain the battery maximum temperature within the safe range of 25 degrees C < T-max < 40 degrees C without significantly affecting the pressure drop.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
