Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Enhancing g‐C3N4 Photocatalytic Activity: K‐Doping and CuO Heterojunction for Selective CO2 Conversion to CH4

open access: yesElectron, EarlyView.
The CuO/K‐g‐C3N4 heterostructure photocatalyst achieves selective CO2 reduction to CH4 (93.03% selectivity) under visible‐light irradiation. K‐doping enhances crystallinity, whereas CuO forms a p‐n heterojunction to promote charge separation and electron transfer.

Influence of Structural and Environmental Parameters on Solar Air Collector Performance

open access: yesEnergy Science &Engineering, EarlyView.
Increasing air gap depth and mass flow rate significantly enhances the thermal performance of solar air collectors, with optimal performance achieved at an 8.5 cm air gap and 0.01318 kg/s mass flow rate. Air gap depth is identified as the dominant factor influencing system efficiency.

Spontaneous hemoperitoneum in a 29‐week pregnancy with a history of endometriosis: A case report and review of the literature

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 31-37, April 2025.
Abstract Spontaneous hemoperitoneum in pregnancy (SHIP) is defined as sudden, nontraumatic intraperitoneal bleeding that occurs during pregnancy or up to 42 days postpartum. The incidence ranges between 4 and 4.9 per 100 000 births. Although seen rarely, it is associated with perinatal morbidity and mortality due to maternal hemodynamic instability ...

Fiscal Policy Regimes in Resource‐Rich Economies

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We analyse fiscal policy in resource‐rich economies using a novel Bayesian regime‐switching panel model. The identified regimes capture pro‐ or countercyclical fiscal behaviour by allowing regime‐specific shifts in the average fiscal stance, while the switches between the regimes have the interpretation of changes in fiscal policy.

Controlling Growth of Ultrasmall Sub‐10 nm Silver Nanoparticles From Cotinus coggygria Scop. Extract and Evaluation of Its In Vitro Anti‐Breast Cancer, Antioxidant and Antimicrobial Activity

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT This study highlights the potential use of Cotinus coggygria Scop. plant extract in a single‐step synthesis of biocompatible and ultrasmall AgNPs for in vitro applications. Herein, microscopic analyses revealed that AgNP exposure did not induce appreciable morphological changes in CRL‐4010 cells, whereas MCF‐7 and MDA‐MB‐231 cells exhibited ...

Efficacy of Hand Gestures and the Hand as Foot Teaching Method Compared to Traditional Methods in Medical and Dental Education: A Scoping Review

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Objective The “Hand‐as‐Foot” teaching method is an innovative, hands‐on approach that uses gesture‐based movements to represent anatomical structures and functions. It has been used successfully in medical education to help simplify and communicate complex ideas. However, its use in dental education remains relatively unexplored.

Exploring the association between vitamin C intake and gingival bleeding tendency in healthy, non‑deficient young adults

open access: yesJournal of Periodontology, EarlyView.
Abstract Background The aim of this study is to investigate the relationship between reported vitamin C intake and gingival bleeding severity. Methods In this cross‐sectional study, 336 participants were screened, and 262 (118 females, 144 males) were eligible. Vitamin C intake was derived from the Food Frequency Questionnaire (FFQ).

Measuring Organizational Resilience in a Resource‐Constrained Environment: An Empirical Study of Micro‐and‐Small‐Service‐Enterprises (MSSEs) in Nigeria

open access: yesStrategic Change, EarlyView.
ABSTRACT There is growing evidence that a preponderance of resilience indicators discussed in management scholarship is often developed with limited consideration of the context in which micro‐and‐small‐service enterprises (MSSEs) operate. Given their strategic relevance to developing economies, it thus becomes necessary to understand the meaning of ...
