Metallic biomaterials, including traditional bioinert materials (such as stainless steel, cobalt-chromium alloys, pure titanium, and titanium alloys), novel biodegradable metals magnesium zinc iron biomedical metallic glasses, have been widely used studied various implants devices. Many scientists researchers investigated their superior biomechanical properties, corrosion behavior, biocompatibility. However, surface characteristics are of extreme importance due to continuing interactions between the surface/interface an implanted biomaterial surrounding physiological environment.

In recent years, advancements in dental implants have posed new challenges for the use of traditional orthopedic materials. This study prepared novel Ti-xNb-5Ta alloys via arc-melting and comprehensively evaluated effects Nb content on microstructure, mechanical properties, elastic modulus, electrochemical behavior, vitro performance. Interestingly, with different contents exhibited distinct properties. The results indicated that 10 13 wt.% surpassed TA4G surgical implant standard strength while offering a lower modulus greater elongation. Electrochemical experiments showed corrosion resistance improved increasing content. Furthermore, CCK-8 assay results, ALP semi-quantitative analysis, RT-PCR demonstrated enhanced early osteogenic differentiation human bone marrow stromal cells (hBMSCs). work not only reveals potential as biomedical materials but also offers insights developing biomaterials.

The toxicity of lunar dust (LD), anecdotally reported by Apollo astronauts, raises concerns for future missions involving prolonged human presence on the Moon. LD is thought to involve oxidative stress driven nanophase metallic iron (np-Fe0), a peculiar feature LD. In life-supporting habitat, np-Fe0 embedded in amorphous phases may react with O2 prior accessing lung, complicating assessments. Due limited availability real samples, toxicological evaluations rely simulants (LDS). A novel Simulant Moon Agglutinate (SMA), composed glassy matrix np-Fe0, was produced and ball milled an inert atmosphere expose non-oxidized Fe0 surface centers obtain respirable particle size. Physicochemical properties, activity, release simulated body fluids were assessed selected SMA samples. aged air, kinetics free radical generation revealed strong redox activity that decreased aging. After ageing 1 month, still active generating radicals, higher extent other like JSC-1A-vf, highlighting key role eliciting reactivity. vitro tests showed caused no cell membrane damage, suggesting mechanisms might radicals differ from terrestrial toxic dust, such as quartz.
