Translation and discussion of Leon Brillouin's 1922 paper titled: Diffusion of light and X‐rays by a transparent homogeneous body: Influence of thermal agitation

open access: yesJournal of Microscopy, EarlyView.
Abstract In 1922, Léon Brillouin introduced the idea of light scattering from thermal fluctuations, in a paper titled: ‘Diffusion de la lumière et des rayons X par un corps transparent et homogéne, influence de l'agitation thermique’. Brillouin's mathematical treatment elegantly unifies principles from thermodynamics, optics and electromagnetic theory (

Soft Tissue Substitutes: Current Biomaterials and Indications at Teeth and Implant Sites

open access: yesJournal of Periodontal Research, EarlyView.
This manuscript provides an updated overview of the current evidence on soft tissue graft substitutes for teeth and dental implants. When appropriately indicated, these biomaterials offer a reliable, less invasive alternative to autogenous grafts, effectively improving root coverage, keratinized mucosa width, and soft tissue thickness with reduced ...

Soft‐Tissue Integration of Dental Implants: Formation, Maintenance, and Relevance for Peri‐Implant Health

open access: yesJournal of Periodontal Research, EarlyView.
Sixty years after the introduction of dental implants, it is clear that soft‐tissue integration is as essential as osseointegration. This review outlines how peri‐implant soft tissues develop, protect, and sometimes fail, revealing key knowledge gaps and new opportunities to improve long‐term implant stability.

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Pre‐Operative Intraoral Ultrasound Features of Benign and Malignant Oral Lesions: An Exploratory Pilot Study

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective To evaluate intraoral‐ultrasound (ioUS) features of benign and malignant oral lesions. Methods In this prospective cross‐sectional study, patients with oral soft tissue lesions underwent ioUS followed by biopsy within 2 weeks. Sonographic features: size, echogenicity, cystic areas, calcifications, margins, and vascularity were ...
