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

open access: yesAdvanced 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.

Neutral atmosphere dynamics

open access: yesEos, Transactions American Geophysical Union, 1971
Articles on atmospheric winds and waves in the thermosphere and directly related ionospheric effects are compiled in this bibliography. The articles were published during the period from January 1967 to about October 1970 by authors, at least one of whom worked for an American institution.

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

open access: yesAdvanced 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.

Internal climate variability and projected future regional steric and dynamic sea level rise

open access: yesNature Communications, 2018
As the global climate becomes warmer, the associated rising sea level could pose significant threats to island and coastal communities. Here the authors show that internal climate variability plays a key role in determining this sea level rise ...

Dynamical atmospheric cluster model

open access: yesAtmospheric Research, 2010
Dynamical behavior of atmospheric molecular clusters was investigated. A model was developed to describe the evolution, concentration and sources of atmospheric clusters. The model includes sources of monomers, monomer - i-mer collisions and evaporation of i-mers. The developed model is agile and flexible.

Evaluating Dielectric Properties for Semicrystalline Thermoplastics to Analyze the Thermal and Rheological Properties in Laser‐Based Powder Bed Fusion of Plastics

open access: yesAdvanced Engineering Materials, EarlyView.
This study aims to establish a link between the dielectric properties of polyamide 12 (PA12) and its thermal and rheological properties using dielectric analysis (DEA). A standardized methodology is introduced to determine melting and crystallization temperatures.

Reactive Interaction and Wetting of Fe‐ and Mn‐Containing, Secondary AlSi Alloys with Manganese Oxide Ceramic Filter Material for Fe Removal

open access: yesAdvanced Engineering Materials, EarlyView.
Fe‐ and Mn‐containing AlSi alloys undergo aluminothermic reaction with Mn oxide in sessile‐drop and crucible experiments forming poor‐wetting Al2O3 while Mn enriches in the alloy. Primary Fe‐containing particles are preferentially attached to the Mn oxide.
