Electrochemical corrosion behavior of α-titanium alloys in simulated biological environments (comparative study).

Titanium (Ti) and its alloys are widely utilized in orthopedic and dental applications due to their favorable mechanical properties and biocompatibility. Notably, titanium exhibits excellent corrosion resistance and can form a stable oxide layer, ensuring the longevity and functionality of implants in challenging physiological environments. This study investigates the corrosion behavior of α-Ti alloy in physiological saline solutions, emphasizing the role of key biomolecules found in the human body, including albumin, glycine, and glucose, as well as additional substances such as hydrogen peroxide (HO) and hydroxyapatite (Hap).

Reassessment of Electrical and Dielectric Properties in the Borophosphate Glass System: A Promising Solid Electrolyte for High-Temperature Batteries.

This study investigates the conduction mechanism of ternary sodium borophosphate glass 30NaO-(70 - )BO-PO with 0 ≤ ≤ 35 mol % from a different perspective, focusing on previously unreported high-temperature electrical and dielectric properties for potential solid electrolytes in high-temperature batteries. The glass composition with BO/PO = 1 exhibits a conductivity of approximately 10 S/cm at 250 °C. Dielectric analysis supports this improved conduction, showing higher dielectric values and minimal energy dissipation during storage, indicating promising conductivity and favorable dielectric properties.

High extraction and excellent anti-UV and anti-oxidant proprieties of lignin from Reseda Luteola L. waste by organosolv process.

Lignin is an abundant natural biopolymer found in plant cell walls. Lignin can come from tinctorial plants, whose residual biomass after dye extraction was typically discarded as waste. The main objective of this study was to extract lignin from the residual biomass of Reseda luteola L.

Poly[(μ(3)-hydrogenphosphato)(4H-1,2,4-triazole-κN(1))zinc].

The asymmetric unit of the title compound, [Zn(HPO(4))(C(2)H(3)N(3))](n), contains one Zn(2+) cation, one (HPO(4))(2-) anion and a 1,2,4 triazole ligand. The Zn(2+) cation is coordinated in a quite regular tetra-hedral geometry by O atoms from three phosphate groups and a tertiary N atom from the triazole ring. Each phosphate anion is connected to three Zn(II) cations, leading to a series of corrugated organic-inorganic layers parallel to the ac plane.
