Salagean-type harmonic univalent functions

open access: yes, 2003
We take the Sakaguchi class of analytic univalent functions which are starlike with respect to symmetric points in the open unit disc ∆ and extend it to the complex-valued harmonic univalent functions in ∆.

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.

Initial Coefficient Estimates for Bi-Univalent Functions Related to Generalized Telephone Numbers

open access: yesJournal of Mathematics
This study defines three novel classes of bi-univalent functions connected to generalized telephone numbers for the first time. We produced assessments about the Taylor–Maclaurin coefficients a2 and a3 and Fekete–Szegö functional problems for functions ...

Electrodialysis Treatment of Nitrate‐Contaminated Groundwater Using Modified Cation‐Exchange Membranes

open access: yesJournal of Applied Polymer Science, EarlyView.
Monovalent selectivity in ion‐exchange membranes is enhanced through dielectric exclusion, electrostatic repulsion, and size‐sieving mechanisms, often acting synergistically. Polyethyleneimine modification and glutaraldehyde crosslinking enable selective electrodialysis of nitrate‐contaminated groundwater, achieving 99% nitrate removal with reduced ...

Evaluating the (comparative) safety profile of the novel oral polio vaccine type 2 using individual case safety reports in VigiBase

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Novel oral polio vaccine type 2 (nOPV2) was used under the WHO emergency use listing for circulating vaccine‐derived polio virus (cVDPV) outbreaks from 2021 to 2023. We assessed nOPV2 adverse events following immunization (AEFIs) and compared its safety profile to other vaccines using VigiBase.

Scalable Separation and Purification of M13‐Bacteriophage‐Derived Particles Containing Artificial Single‐Stranded DNA Produced by Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Single‐stranded DNA (ssDNA) solutions are promising innovations shaping the future of genetic research and medical therapies. In principle, biotechnological mass production of ssDNA can be achieved using Escherichia coli in a high‐cell density fed‐batch process by secreting phagemid particles derived from the filamentous M13 bacteriophages ...

Heterostructure‐driven graded energy band structure in halide perovskite films

open access: yesBulletin of the Korean Chemical Society, EarlyView.
A solvent‐free transfer route enables heterostructure‐driven graded energy band engineering in halide perovskite films. Abstract Perovskite/perovskite heterostructures provide a promising platform for engineering optoelectronic properties through compositional and energetic control.
