Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Citric‐Acid Polyester‐Modified Melamine–Formaldehyde Resins: Mechanistic Insights and Implications for Greener Decorative Laminates

open access: yesJournal of Applied Polymer Science, EarlyView.
Driven by the need for more sustainable materials in the laminate industry, poly(glycerol citrate) was introduced as a bio‐based modifier that significantly altered the cure kinetics and structural evolution of melamine–formaldehyde resins. Correlated FTIR, DSC, TGA, and rheological analyses revealed accelerated network formation, enabling lower ...

Quantum‐Mechanical Wave Functions in Singular Potentials: Linear and Nonlinear States

open access: yesAdvanced Physics Research, EarlyView.
The attractive singular potential −1/r2$-1/r^2$ gives rise to the quantum collapse in the 3D linear Schroedinger equation. The article summarizes theoretical results demonstrating suppression of the collapse and creation of the missing ground state (GS) in a gas of bosonic particles, carrying an electric dipole moment, which are pulled to the central ...

Meniscal Ramp Lesions Are More Commonly Detected on Magnetic Resonance Imaging Than Arthroscopy in Patients With Anterior Cruciate Ligament Tears

open access: yesArthroscopy, EarlyView.
Purpose To assess the prevalence of, and factors associated with, meniscal ramp lesions in patients with anterior cruciate ligament (ACL) tears. Methods All patients who underwent primary ACL reconstruction (ACLR) during 2018 were evaluated. Preoperative magnetic resonance imaging (MRI) scans and surgical reports were reviewed searching for the ...
