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

Advanced Engineering Materials, Volume 27, Issue 14, July 2025.
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.

Modeling Temperature‐ and Rate‐Dependent Behavior of Soft Soils: A Thermo‐Visco‐Hypoplastic Approach

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 8, Page 2076-2091, 10 June 2025.
ABSTRACT Temperature effects become important in a number of geotechnical applications, such as nuclear waste disposal facilities, buried high‐voltage cables, pavement, energy geostructures and geothermal energy. On the other hand, soft soils act time‐ and strain rate dependent.

Compressibilidade de um Argissolo Vermelho-Amarelo trafegado e escarificado Compressibility of a trafficked and chiseled Alfisol

Ciência Rural, 2012
O tráfego de máquinas agrícolas é considerado uma das principais fontes da compactação do solo. Uma prática utilizada para minimizar os efeitos da compactação é a escarificação, porém a haste escarificadora pode causar compactação subsuperficial.
