Here, the hydromagnetic entropy optimized flow of a hybrid (Pb + FeO/CHO) nanoliquid by a curved stretchable surface is addressed. The Darcy-Forchheimer model is utilized for porous space. Lead (Pb) and ferric oxide (FeO) are considered the nanoparticles and ethylene glycol (CHO) as the base liquid. Thermal expression consists of dissipation and ohmic heating. Entropy generation is under consideration. The Cattaneo-Christov heat flux impact is discussed. Non-dimensional partial expressions by adequate transformations have been reduced to ordinary differential systems. The ND-solve technique is implemented for numerical solutions of dimensionless systems. Graphical illustrations of velocity, thermal field and entropy against influential variables for both nanoliquid (Pb/CHO) and hybrid nanoliquid (Pb + FeO/CHO) are presented. Graphical illustrations of velocity, thermal field and entropy against sundry variables for both nanoliquid (Pb/CHO) and hybrid nanoliquid (Pb + FeO/CHO) are presented. Influences of sundry variables on the Nusselt number and drag force for both nanoliquid (Pb/CHO) and hybrid nanoliquid (Pb + FeO/CHO) are examined. A higher thermal relaxation time tends to intensify the heat transport rate and temperature. An increment in the magnetic variable leads to an enhancement of the entropy and thermal field. An improvement in liquid flow is seen for volume fraction variables. Velocity against the porosity variable and Forchheimer number is reduced. The Brinkman number leads to maximization of entropy generation.

Rheumatoid arthritis (RA) remains a challenging autoimmune disease due to its complex and heterogeneous pathophysiology, which complicates therapeutic and diagnostic efforts. Advances in DNA nanotechnology have introduced DNA nanomaterials as promising tools to overcome these barriers. This review focuses on three primary categories of DNA nanomaterials applied in RA: DNA nanostructures, DNA aptamers, and DNA-modified nanoparticles.

In recent years, modulation of microglial phenotype transformation has emerged as a promising strategy for treating central nervous system disorders. Aurantii Fructus Immaturus (Zhishi), a traditional Chinese medicine with versatile applications, contains p-Synephrine (p-SYN) as its principal bioactive compound, recognized for its anti-inflammatory efficacy. However, the molecular mechanisms underlying these effects remain unclear.

The evolution of the lunar magnetic field can reveal the Moon's interior structure, thermal history, and surface environment. The mid-to-late-stage evolution of the lunar magnetic field is poorly constrained, and thus, the existence of a long-lived lunar dynamo remains controversial. The Chang'e-5 mission returned the heretofore youngest mare basalts from Oceanus Procellarum uniquely positioned at midlatitude.

Microfluidic droplets, with their unique properties and broad applications, are essential in in chemical, biological, and materials synthesis research. Despite the flourishing studies on artificial intelligence-accelerated microfluidics, most research efforts have focused on the upstream design phase of microfluidic systems. Generating user-desired microfluidic droplets still remains laborious, inefficient, and time-consuming.

We have examined the structural and electron transport properties of a swallow-tailed ,'-bis(1-heptyloctyl)-perylene-3,4:9,10-bis(dicarboximide) () in thin films. A comprehensive analysis of material with the use of X-ray scattering methods evidenced the appearance of a new soft-crystalline mesophase that was induced by thermal processing of the swallow-tail PDI derivative. By combining electrical measurements with grazing-incidence wide-angle X-ray scattering (GIWAXS), we show that these morphological changes of thin films boost their charge transport in the organic field-effect transistor (OFET) configuration.
