Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

open access: yesJournal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

Diatoms from Southwest Greenland.

open access: yes, 1973
In material collected in 195? and 19?0 in localities situated between 59° 44' N and 61 °22'N in SW Greenland a total of 465 oligohalobous diatoms and 260 mesohalobous and polyhalobous diatoms is shown, 4 nov. var. and 4 nov. fo. included.

Siliceous sponges or seawater as a silicon source? Tracing silicon burial pathways of the Upper Cretaceous opal‐CT deposits using δ30Si and δ7Li

open access: yesSedimentology, EarlyView.
ABSTRACT Classical models of formation of sedimentary siliceous rocks (flint, chert, opoka) commonly assume that the Cretaceous marine silicon (Si) cycle was primarily biologically controlled, broadly analogous to the modern ocean. In this framework, siliceous sponges are regarded as the principal source of dissolved silica (dSi) to sediment porewaters,

Climate Change and Temperature‐Based Stratification in Shallow Lakes and Ponds in Warm Climate Regions

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Thermal stratification in shallow lakes (< 5 m, > 5 ha) and ponds (< 5 m, < 5 ha) in warm climate regions is understudied. A comprehensive review was done to identify the effects of climate change on stratification patterns, their effects on the ecology of shallow waterbodies and implications for management of shallow waterbodies.
