Biogenic gas nanostructures as ultrasonic molecular reporters. [PDF]

, 2014
Ultrasound is among the most widely used non-invasive imaging modalities in biomedicine, but plays a surprisingly small role in molecular imaging due to a lack of suitable molecular reporters on the nanoscale.

Mechanical and Microstructural Effects of ZrO2 Nanoparticles in Fe20Cr Oxide Dispersion‐Strengthened Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
The influence of oxide nanoparticle synthesis route and concentration on microstructure and high‐temperature performance of additively manufactured oxide dispersion‐strengthened steels is investigated. Comparing laser‐generated and chemically synthesized ZrO2 nanoparticles, the study reveals how dispersion quality, crystal structure and particle size ...

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

Advanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12

Advanced Engineering Materials, EarlyView.
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.

How does study quality affect the results of a diagnostic meta-analysis? [PDF]

, 2005
Background: The use of systematic literature review to inform evidence based practice in diagnostics is rapidly expanding. Although the primary diagnostic literature is extensive, studies are often of low methodological quality or poorly reported.

Microstructural and Mechanical Properties of a Hard Anodic Coating Applied on an Elastically Prestrained Aluminum Substrate

Advanced Engineering Materials, EarlyView.
Prestraining the substrate influences coating formation process. Higher prestraining force leads to higher coating thickness and lower hardness. Increase in prestraining force enhances preliminary damage in hard anodic coating. Fatigue damage mechanisms change for hard anodized prestrained samples.

Mesoporous Silica Microspheres by Super‐Fast Alkaline Etching of Micrometer‐Sized Stöber Particles

Advanced Engineering Materials, EarlyView.
Microscale silica particles are prepared along with a modified, scalable Stöber synthesis using the continuous addition of tetraethoxy silane to an ethanolic solution of ammonia with KCl. Etching with hydroxide ions at 95 °C gave porous analogs within minutes. Monodisperse particles are isolable in high yield after precipitation in ethanol.
