Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

open access: yesJournal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

Tranexamic Acid in Lower Extremity Endoprosthetic Reconstruction for Oncologic Indications: A Retrospective Comparative Study of 617 Patients

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background and Objectives While tranexamic acid (TXA) reduces blood loss in orthopedic surgery, thromboembolic concerns in cancer patients have limited adoption in orthopedic oncology. This study evaluated TXA efficacy and safety in patients undergoing endoprosthetic reconstruction for oncologic indications.

Effect of Heat Treatment Parameters on Microstructure, Hardness, and Corrosion Resistance of Martensitic Stainless Steel X30Cr13 (AISI 420B)

open access: yesMaterials and Corrosion, EarlyView.
The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these

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.
