Advanced Engineering Materials, EarlyView.Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...

Impact of Iron Contamination on Liquid Properties and Microstructural Evolution in AlSi20
Advanced Engineering Materials, EarlyView.Recycled aluminum is much more energy conservative and sustainable than primary aluminum. However, the iron contamination in secondary aluminum is vastly responsible for the degradation of the material properties. Herein, it is aimed to evaluate the influence of iron contamination in hypereutectic Al–Si alloy through thermodynamic as well as ...

The X-Ray Emission Reveals the Coronal Activities of Semi-detached Binaries
The Astrophysical JournalX-ray emission is an important tracer of stellar magnetic activity. We carried out a systematic correlation analysis for the X-ray luminosity $\mathrm{log}{L}_{{\rm{X}}}$ , bolometric luminosity $\mathrm{log}{L}_{\mathrm{bol}}$ , and X-ray activity ...

Advanced Engineering Materials, EarlyView.Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...

A Possible Explanation of W-type Phenomena in V694 Peg
The Astrophysical JournalThree sets of complete multicolor light curves of V694 Peg observed in 2013, 2015, and 2019 were presented and analyzed. Our photometric solutions show that this system was an A-type shallow contact binary in 2013 and 2015 while it converted to a W-type ...

The Lifetime of Binary Stars [PDF]
International Astronomical Union Colloquium, 1977 AbstractThe concept of the “lifetime” of a population of binaries is applicable only to those of low binding energy, i.e. wide pairs. Of several possible methods of estimating a lifetime, that based on the average change in binding energy due to non-disruptive encounters appears to be the best.
