Neurofilament light chain (NfL) is an early nonspecific biomarker in neurodegenerative diseases and traumatic brain injury, indicating axonal damage. This work describes the detailed structural characterization of a selected primary calibrator with the potential to be used in future reference measurement procedure (RMP) development for the accurate quantification of NfL. As a part of the described workflow, the sequence, higher-order structure as well as solvent accessibility, and hydrogen-bonding profile were assessed under three different conditions in KPBS, artificial cerebrospinal fluid, and artificial cerebrospinal fluid in the presence of human serum albumin.

Formic acid (HCOOH) is one of the essential molecules for CO utilization including methanol synthesis and hydrogen carriers. In this study, we have investigated the chemical processes of hydrogen and HCOOH on a dilute-alloy Pd-Cu(111) surface using high-resolution X-ray photoelectron spectroscopy (HR-XPS) and density functional theory (DFT) calculations. The present Pd-Cu(111) surface was prepared at 500 K, and the observed core-level shifts of Pd 3d indicate that Pd atoms were located at the surface and subsurface sites: 335.

Article Synopsis
- Ammonia is seen as a promising hydrogen carrier due to its efficiency, easier storage, and established infrastructure, allowing for on-demand hydrogen generation via electrochemical ammonia oxidation.
- The study investigates bimetallic PtRh alloy catalysts, which show improved performance in the ammonia oxidation reaction (AOR) compared to standard platinum catalysts, indicating lower energy requirements and better activity.
- X-ray photoelectron spectroscopy reveals that the Rh component modifies the electronic properties of Pt, reducing issues with catalyst poisoning, thereby enhancing the understanding of AOR mechanisms for future catalyst design.
Towards Accurate Biocompatibility: Rethinking Cytotoxicity Evaluation for Biodegradable Magnesium Alloys in Biomedical Applications.

Magnesium and its alloys represent promising candidates for biomedical implants due to their biodegradability and mechanical properties, which are similar to natural bone. However, their rapid degradation process characterized by dynamic pH fluctuations and significant hydrogen gas evolution during biocorrosion adversely affects both in vitro and in vivo assessments. While the ISO 10993-5 and 12 standards provide guidelines for evaluating the in vitro biocompatibility of biodegradable materials, they also introduce testing variability conditions that yield inconsistent results.

Objective: The objective of this study is to synthesize and comprehensively characterize a novel iodine-containing coordination compound, di-aminopropionic acid hydrogen tri-iodide. This involves determining its structural, physicochemical, and thermal properties, as well as evaluating its antimicrobial activity against a range of bacterial strains, including multidrug-resistant pathogens. The aim is to explore the potential of this compound as a candidate for developing new antibacterial agents to address the challenge of antibiotic resistance.
