Comparative Analysis of the Mechanical, Surface, and Dimensional Properties of 3D‐Printed Aligners: Influence of Printer Type and Nitrogen‐Assisted Post‐Curing

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives This study aimed to compare the mechanical, surface, and dimensional properties of 3D‐printed clear aligners (CA) fabricated using liquid crystal display (LCD) and digital light processing (DLP) 3D printing systems with nitrogen treatment. Materials and Methods Specimens were manufactured using LCD (Uniz NBEE) and DLP (Nextdent 5100)

VUV and mid‐UV photoabsorption cross sections of thin films of glycine and alanine: Application to their photochemistry in the solar system

open access: yesPhotochemistry and Photobiology, EarlyView.
Thin solid films of pure glycine or alanine (thicknesses ranging from 10 to 700 nm) were prepared on MgF2 windows using a vacuum sublimation/recondensation method. VUV‐UV spectroscopy of these films enabled us to characterize new absorption cross sections for glycine and alanine for VUV‐UV radiations between 120 and 300 nm.

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

open access: yesPolymer Composites, Volume 47, Issue 21, Page 19085-19107, 10 November 2026.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.
