What controls forest litter decomposition? A coordinated distributed teabag experiment across ten mountains

open access: yesEcography, EarlyView.
Litter decomposition in mountainous forest ecosystems is an essential process that affects carbon and nutrient cycling. However, the contribution of litter decomposition to terrestrial ecosystems is difficult to estimate accurately because of the limited comparability of different studies and limited data on local microclimatic and non‐climatic factors.

Single‐ or two‐visits endodontic treatment: Impact of irrigants on surface roughness, microhardness, topography, and fracture resistance of root dentin

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study evaluated the effect of the number of simulated endodontic treatment visits and the type of irrigant on the surface roughness, microhardness, topography, and fracture resistance of root dentin. Bovine roots were distributed into six groups (n = 14) according to the irrigant and number of treatment visits: 0.9% saline solution ...

Fast and Sensitive Measurement of Off‐Flavors in Recirculating Aquaculture Systems

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Geosmin and 2‐methylisoborneol (2‐MIB) are odor‐active compounds responsible for earthy off‐flavors in fish, creating significant quality concerns in recirculating aquaculture systems (RAS). Their extremely low odor thresholds make rapid and highly sensitive detection essential for maintaining product quality and consumer acceptance ...

Carbohydrate‐Based Drug Discovery: Synthetic Strategies and Clinical Applications

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 3, May 2026.
The picture depicts the molecules discussed in the review. On the left side, the general scaffold of sugars is shown. Next to it are four carbohydrate‐based molecules, including remdesivir, islatravir, empagliflozin, and Globo‐H. Remdesivir and islatravir contain a substituted ribose ring attached to a modified nucleobase.

Three-dimensional isotropic perfect lens based on LC-loaded transmission lines

open access: yes, 2005
An isotropic three-dimentional perfect lens based on cubic meshes of interconnected transmission lines and bulk loads is proposed. The lens is formed by a slab of a loaded mesh placed in between two similar unloaded meshes.
