From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ$$ {a}_p\left ...

Experimental and Comparative Study of the Corrosion Behavior of Lean Duplex Stainless Steel in Seawater

open access: yesMaterials and Corrosion, EarlyView.
The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.

Assessment of Electrical Resistance Sensors Sensitivity to Localized Corrosion

open access: yesMaterials and Corrosion, EarlyView.
Are electrical resistance (ER) sensors reliable for localized corrosion detection? This study combines analytical modeling and experimental validation to show the vulnerability of ER sensors. The results demonstrate significant underestimation of the true corrosion depth of localized attacks depending on defect's geometry.

Electrochemical Investigation of Alumina Thin Films for Electronic Packaging

open access: yesMaterials and Corrosion, EarlyView.
Surface morphology of alumina films on copper substrates produced by ALD. Characterization of the alumina film properties by FTIRR (left) and EIS (right). ABSTRACT Thin films of alumina processed by atomic layer deposition (ALD) were electrochemically investigated by impedance spectroscopy (EIS) and linear sweep voltammetry (LSV) as well as material ...

The Application of Telemedicine in Surgery

open access: yesMed Research, EarlyView.
This figure provides an overview of the content presented in this article. Telemedicine is integrated throughout the entire surgical workflow, with distinct applications across the preoperative, intraoperative, and postoperative phases. These applications are enabled by a suite of supporting technologies, while the associated implementation challenges ...
