Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X‐750 Produced by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Performance of Microfiltration Membranes to Turn Processed Water from Hospital Wastewater Treatment Plants (WWTP) into Clean Water

Jurnal Kesehatan
Problems arise when there are tax fees on groundwater use by hospitals. This will, of course, burden the hospital's operational costs. The solution to reducing groundwater use is the use of microfiltration membranes. Microfiltration membranes can be used

Microplastic Human Dietary Uptake from 1990 to 2018 Grew across 109 Major Developing and Industrialized Countries but Can Be Halved by Plastic Debris Removal

Environmental Science and Technology
Microplastics (MPs), plastic particles smaller than 5 mm, are now a growing environmental and public health issue, as they are detected pervasively in freshwater and marine environments, ingested by organisms, and then enter the human body.

Antimicrobial Titanium–Copper Alloys: The Role of Microstructure in Arc‐Melted Compositions

Advanced Engineering Materials, EarlyView.
Copper‐containing titanium alloys show promise in combating orthopedic implant infections. This study explores the influence of heat treatment on Ti‐11.5Cu and Ti‐33Cu alloys, revealing that larger Ti2Cu precipitates (≈5 μm) enhance antimicrobial efficacy through increased surface contact. Results suggest contact sterilization is the primary mechanism,
