ABSTRACT Stainless steel (316L) is widely used in biomedical applications, but concerns persist regarding its long‐term surface properties, particularly varying patient environments over time. This study aims to enhance the properties of 316L stainless through a 1.504 μm tantalum (Ta) coating applied via DC magnetron sputtering. The corrosion and wear behaviours were evaluated different mediums, including human blood (HB), artificial saliva (AS), Ringer's solution (RS), simulated body fluid...

A series of new disubstituted diphenyldithiophosphate complexes cadmium [{(ArO)2PS2}2Cd] (9–12) have been isolated in aqueous media while their donor stabilized adducts [{(ArO)2PS2}2Cd·2C5H5N] (13–16) [(Ar = 2,4-(CH3)2C6H3, 2,5-(CH3)2C6H3, 3,4-(CH3)2C6H3 and 3,5-(CH3)2C6H3)] chloroform. These newly synthesized were characterized by elemental analyses, IR NMR (1H, 13C 31P) spectroscopic analyses. The dithiophosphate ligands are coordinated bidentate to the ion via two thiolate sulfurs....

Abstract Magnetite modified mobil catalytic material number 41 (MCM‐41) nano‐composites have been synthesized for the effective determination and separation of non‐steroidal anti‐inflammatory drugs (diclofenac, ketoprofen, mefenamic acid) using high‐performance liquid chromatography. The magnetite‐modified MCM‐41 were characterized by scanning electron microscopy coupled with energy dispersed spectrum, transmission microscopy, Fourier transform infrared spectroscopy, thermogravimetric...
