Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Synthesis and Interfacial Behavior of Mixed Potassium N‐Lauroyl/N‐Myristoyl Glycinate Surfactants With Varying Alkyl Chain Ratios

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Biodegradable and low‐irritant amino acid–based surfactants have attracted considerable attention as environmentally friendly alternatives to conventional petroleum‐derived surfactants. In this study, a series of acyl amino acid surfactants with identical amino acid head groups but different alkyl chain lengths were synthesized via a modified ...

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

The Heart (qalb)

St Andrews Encyclopaedia of Theology
In the Islamic tradition, the heart is the centre of the human being. Much more than just the physical organ that circulates blood throughout the body, the heart is central to the physical, emotional, intellective, ethical, and spiritual life of Muslims.
