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) ...

In this study, the co-electrodeposition (CED) method was utilized to produce copper metal matrix composite coatings (Cu-MMC) using lab-made sulfate electrolyte and lab-made synthesized nanoparticles of ferrite-aluminum layered double oxide (Fe/Al LDO) as reinforcement. Copper coatings and co-electrodeposited Cu-MMC coatings with Fe/Al LDO nanoparti...

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 ...

The World Health Organization (WHO) estimates that around 70–80% of the world’s population relies on non-conventional medications, most of which are derived from plant-based medicines. Dandelion (Taraxacum officinale) is a widely used medicinal plant in traditional medicine. In recent years, numerous studies have been conducted to impro...

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. ...

In this work, the inverse heat transfer analysis (IHTA) utilizing the Finite Element Method (FEM) has been used to detect the thermal properties of the soil where in situ soil temperature (ST) measurements together with that obtained theoretically are used in the solution. The initial values of the unknowns such as the soil thermal diffusivity are ...
