Abstract Achillea species are known for their healing properties since ancient times. There is extensive literature on their pharmacological action due to their bioactive compounds. The present study aimed to investigate the antioxidant and antimicrobial effects of hydroalcoholic extracts from the inflorescences and leaves of the species Achillea crithmifolia Waldst. and Kit., A. grandifolia Friv. and A. millefolium L. The phytochemical profiles of all extracts were evaluated both by NMR spectroscopy and LC-MS analysis, and the results were consistent with the spectrophotometrically determined total phenolic (TP: 125.42–191.98 mg/g) and total flavonoid (TF: 47.34–180.02 mg/g) contents. All the extracts were tested More >

Abstract Hepatitis B Virus (HBV) infection and heavy alcohol consumption are the two primary pathogenic causes of liver cirrhosis. In this paper, we proposed a deterministic mathematical model and a logistic equation to investigate the dynamics of liver cirrhosis progression as well as to explain the implications of variations in alcohol consumption on chronic hepatitis B patients, respectively. The intricate interactions between liver cirrhosis, recovery, and treatment dynamics are captured by the model. This study aims to show that alcohol consumption by Hepatitis B-infected individuals accelerates liver cirrhosis progression while treatment of acutely infected individuals reduces… More >

Abstract Corn starch (CS) is a renewable, biodegradable polysaccharide valued for its film-forming ability, yet native CS films exhibit low mechanical strength, high water sensitivity, and limited thermal stability. This study improves CS-based films by blending with poly(vinyl alcohol) (PVA) or glycerol (GLY) and using citric acid (CA) as a green, non-toxic cross-linker. Composite films were prepared by casting CS–PVA or CS–GLY with CA at 0%–0.20% (w/w of starch). The influence of CA on physicochemical, mechanical, optical, thermal, and water barrier properties was evaluated. CA crosslinking markedly enhanced the tensile strength, water resistance, and thermal stability More > Graphic Abstract

Abstract To study the behavior of structural dynamics, ionic conductivity and ion transport properties, the gel polymer electrolytes (GPEs) was developed using polyvinyl alcohol in combination with potassium iodide, dimethyl sulfoxide, ethylene carbonate, propylene carbonate and tetra-N-propylammonium iodide (C₁₂H₂₈IN), The GPEs were synthesized via a solution mixing technique, systematically varying the tetra-N-propylammonium iodide concentration to optimize ionic transport properties. The gel polymer electrolytes (GPEs) preparation was initially dissolving the potassium iodide and tetra-N-propylammonium iodide in a measured combination of ethylene carbonate, propylene carbonate, and dimethyl sulfoxide within a glass container. Subsequently, polyvinyl alcohol (PVA) was introduced into… More >

Abstract Objectives: The evidence remains insufficient and controversial for evaluating modifiable parameters—such as vitamin D, calcium, ferritin, and uric acid—as preclinical biomarkers to contribute to the prevention and early diagnosis of prostate cancer, a disease with a prevalence of up to 10%–20% in men over 50 and strongly associated with environmental factors including diet (high in fat and red meat), obesity, physical inactivity, and carcinogen exposure. This study aims to investigate the potential biomarker role of vitamin D, calcium, ferritin, and uric acids in reducing the risk of prostate cancer (PCa). Methods: The case-control design was… More >

Abstract This study investigates the development of an oil palm trunk (OPT) high-performance flame-retardant composite derived from an inexpensive and sustainable biomass source, processed using sodium chloride (NaCl) as a low-cost flame retardant, polyvinyl alcohol (PVA) as an adhesive, and calcium carbonate (CaCO₃) as an additive. The work aims to address the inherent flammability of OPT and to enhance its mechanical performance, dimensional stability, and fire resistance in an environmentally friendly and cost-effective manner. Results indicate that a 10% NaCl treatment optimally improves the performance of the composite, increasing bending strength (MOR) from 5.95 to 12.61 MPa… More > Graphic Abstract

Abstract Polymeric materials have emerged as a promising alternative to electrolytic solutions in energy storage applications. However, high crystallinity and poor ionic conductivity are the main barriers restricting their daily application. In this study, we propose a polymer electrolyte system consisting of methylcellulose-polyvinyl alcohol (MC-PVA) blend as host material and lithium trifluoromethanesulfonate (LiCF₃SO₃) as dopant, which was prepared using the solution-casting method. The electrochemical impedance spectroscopy (EIS) analysis revealed a maximum conductivity of 5.42 × 10⁻⁶ S cm⁻¹ with 40 wt.% LiCF₃SO₃. The key findings demonstrated that the variation in the dielectric loss (ε_i) and dielectric constant (ε_r) was… More >

Abstract Sugarcane bagasse (SCB) is a promising natural fiber for bio-based composites, but its high moisture absorption and poor interfacial adhesion with polymer matrices limit mechanical performance. While chemical treatments have been extensively explored, limited research has addressed how thermal treatment alone alters the surface properties and reinforcing behavior of SCB fibers. This study aims to fill that gap by investigating the effects of heat treatment on SCB fiber structure and its performance in starch/poly (vinyl alcohol) (PVA) composites. Characterization techniques including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning… More >

Abstract Primary diamines play an important role in the chemical industry, where they are widely used as raw materials for the manufacture of pharmaceuticals and polymers. Currently, primary diamines are mainly derived from petroleum, while harsh or toxic conditions are often needed. Biomass is abundant and renewable , which serves as a promising alternative raw material to produce primary diamines. This review primarily focuses on the synthesis of 2,5-bis(aminomethyl)furan (BAMF), a bio-based diamine with potential as a biomonomer for polyamides and polyureas. Specifically, this review emphasizes the synthesis of BAMF from three biomass-derived alcohols and aldehydes,… More > Graphic Abstract
