Changes in the Pterygopalatine and Midpalatal Sutures After Rapid Palatal Expansion With Tooth‐Bone‐Borne (MARPE) and Tooth‐Borne (Hyrax) Appliances

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This retrospective cohort study aimed to compare the effects of tooth‐bone‐borne mini‐implant‐assisted rapid palatal expansion (MARPE) and tooth‐borne (Hyrax) rapid palatal expansion (RPE) techniques on the pterygopalatine suture (PPS) and the opening pattern of the midpalatal suture (MPS).

Peri‐implantitis—Is it mainly a clinician‐initiated complication of implant therapy?

open access: yesPeriodontology 2000, EarlyView.
Abstract Aim The high prevalence of peri‐implantitis is concerning, with a growing consensus that the majority of cases are complications initiated by clinician‐related errors rather than classic pathology. A primary predisposing factor for peri‐implantitis is exposure of the micro‐rough implant surfaces to the peri‐implant sulcus after treatment ...

Digitization connects scattered specimens and enables new historical research: Plants from the Lady Franklin Bay Expedition (1881–1884)

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1087-1094, July 2026.
Widespread museum digitization initiatives have made the world's herbaria more accessible than ever, launching a renaissance of specimen use. We highlight the value of digitization to bolster both scientific and historical research using the specimens from the Lady Franklin Bay Expedition (1881–1884) to the Canadian arctic, remembered for its tragedy ...

The effects of vibration on defective solder joints [PDF]

open access: yes
Vibration testing is important in electronics to predict how different components and solder joints behave under stress. In different operating environments, such as vehicles and machines, electronics are exposed to vibration.

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.
