High‐Resolution and Surface‐Sensitive Tip‐Enhanced Raman Spectroscopy Characterization of Strained‐Silicon Devices through Cleanroom‐Compatible Plasmonic Probes

Advanced Materials Interfaces, Volume 12, Issue 10, May 19, 2025.
This paper demonstrates how Tip‐Enhanced Raman Spectroscopy (TERS) can detect diverse levels of strain in a SiGe‐Si structure in less than 20 nm of depth with lateral resolution under 100 nm. The measures are performed with a TiN‐coated probe, which secures a remarkable enhancement of the optical signal, while being chemically stable to allow TERS to ...

Knowledge is not power: Learning in polycentric governance systems

Review of Policy Research, Volume 42, Issue 3, Page 444-465, May 2025.
Abstract The link between knowledge and decision‐making in polycentric systems is shaped by the process of collective learning, where policy actors participate in multiple policy forums to acquire, translate, and disseminate knowledge. This article argues that the relationship between learning and participation in polycentric systems differs for actors

A Review of the Status of Sharks, Rays and Chimaeras of Panama to Guide Research and Conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT Chondrichthyan fishes (sharks, rays and chimaeras) are a group of high conservation concern globally. Species are impacted by varying threats, although fishing pressure is the primary stressor causing population declines. Panama comprises both Pacific and Caribbean coastlines with a diversity of estuarine and marine habitats supporting small ...

Genetic Dissection of Cyclic di‐GMP Signalling in Pseudomonas aeruginosa via Systematic Diguanylate Cyclase Disruption

Microbial Biotechnology, Volume 18, Issue 4, April 2025.
All 32 diguanylate cyclase (DGC)‐encoding genes of P. aeruginosa PA14 were interrupted by premature STOP codons, introduced through a multiplexed cytosine base‐editor. The synthesis of c‐di‐GMP was impaired in the resulting strain lacking all 32 DGCs (strain PA14Δ32). Phenotypic analysis confirmed major behaviour changes in P. aeruginosa PA14Δ32, which
