An antimicrobial alloy includes titanium, niobium, and silver. Further, the antimicrobial alloy includes between 5 and 30 atomic percent niobium, up to 3 atomic percent silver, the remaining atomic percentage is titanium, and the alloy does not include zirconium. The antimicrobial alloy has a predominantly beta-titanium crystal structure and an elasticity modulus ranging from 60 to 85 GPa. A process for manufacturing the antimicrobial alloy. The antimicrobial alloy prepared by the method can be used in bioimplants.

A method to form a metal matrix composite reinforced with eggshell (ES). The method includes preparing an ES powder, blending and milling the ES powder with at least one metal powder selected from the group consisting of magnesium (Mg), zirconium (Zr) to form a powder mixture, compacting and sintering the powder mixture to form the metal matrix composite. In addition, a Mg—Zr-ES metal matrix composite with improved corrosion resistance, having an amount of magnesium from 95 to 97 wt. %, an amount of zirconium from 1 to 2 wt. %, and an amount of ES from 1 to 4 wt. %, may be used for biomedical applications.

A membrane distillation apparatus includes a housing and an impeller. The housing includes a hot medium compartment, a cold medium compartment, an air gap compartment, a membrane, and a thermally conductive plate. The hot medium compartment includes a hot medium inlet configured to receive a hot medium stream including water. The cold medium compartment includes a cold medium inlet configured to receive a cold medium stream. The membrane defines pores that are sized to allow water vapor originating from the hot medium stream to pass from the hot medium compartment through the membrane to the air gap compartment. The thermally conductive plate and the cold medium stream are cooperatively configured to condense the water vapor from the hot medium stream. The air gap compartment is substantially filled with air and includes a permeate outlet configured to discharge the condensed water vapor. The impeller is disposed within the air gap compartment.

A hybrid membrane, particularly of polyacrylonitrile (PAN)/graphene oxide (GO)/SiO, separates oil and water even from emulsions. The membrane can be made by one-step electrospinning, adding GO and SiOnanofillers in PAN in various concentrations. The nanofillers may be uniformly embedded in the nanofibrous structure of the electrospun hybrid membrane, with GO mainly embedded inside the PAN nanofibers and may cause knots, and/or SiOnanoparticles embedded on the nanofiber surface and may form micro-nano fiber surface protrusions. Hierarchical structures formed can have enhanced hydrophilicity due to oxygen-containing groups on both SiOand GO, and have &#x3e;99% oil rejection from oil-water emulsions. Separation flux and phase rejection of gravity separation may be enhanced by incorporation of nanofillers, which may also enhance membrane mechanical properties. Separated water flux may be enhanced from 2600 (pure PAN) to 3151 Lmhfor the hybrid.
