Aromatic plants of the Lamiaceae family are valuable food and medicinal sources due to their antioxidant, antimicrobial, antispasmodic, expectorant, carminative, antiulcer, stimulant, anticancer, anti-proliferative, and diuretic effects. Biologically active compounds obtained from plant resources have gained more attention nowadays, due to the cons...

Hydrogels have emerged as promising materials in regenerative medicine due to their biocompatibility and tunable properties. Polyurethane (PU), a versatile polymer, is renowned for its excellent mechanical properties and stability. However, its inherent hydrophobicity limits its application in biomedical fields. To overcome this limitation, polyure...

Poly(L-lactide) (PLLA), a biodegradable polymer with properties comparable to conventional plastics, is limited by its inherent brittleness and thermal instability. This study explores the enhancement of PLLA properties through the synthesis of ABA-type block copolymers with distinct soft middle blocks—polyester poly(methylricinoleate) (PMR) ...

Food, especially cereals and vegetables, water and air are the major source of exposure to toxic metals like cadmium (Cd), lead (Pb), arsenic (As) and mercury (Hg). Their accumulation in the human body can lead to harmful effects over time. The EFSA panel on contaminants in the food chain (CONTAM) established a tolerable weekly intake (TWI) for Cd,...

This study examined the characteristics of granulated activated carbon (GAC) as an adsorbent for the removal of organic matter from the surface water of the Jala River. The adsorbent was characterized by XRD, FTIR, Raman spectroscopy, BET and SEM/EDS methods, while a detailed physicochemical characterization was performed for the water sample. The ...

Silica gel is a widely used desiccant with a high water sorption capacity, influenced by factors such as specific surface area, pore volume, and pore size. This study develops mathematical models using multiple linear regression analysis (MLRA) to predict the water sorption capacity of silica gel based on experimental data. Independent variables in...

Stone samples were sampled from three fields: Field A, Field B, and Field C. In this work, chemical and mineralogical analysis of the stone was performed. The chemical analysis of the stone was done by volumetric, complexometric, spectrophotometric, gravimetric and X-ray fluorescence analysis (XRF). Mineralogical analysis was done by XRD analysis. ...
