Hydrogen Reduction of Synthetic Fe2O3 Pellets: The Role of Calcium Oxide in Porosity Evolution and Reduction Kinetics

open access: yessteel research international, EarlyView.
At 800 °C, hematite pellets containing 0.9 wt% CaO reduce in hydrogen at rates 1.2–1.4 times those of pure pellets. The inward‐moving reaction front supports a topochemical description, and FeO‐to‐Fe kinetics are consistent with mixed control by interfacial reaction and intrapellet diffusion.

Periodontitis and atherosclerotic cardiovascular disease: A critical appraisal

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract In spite of intensive research efforts driving spectacular advances in terms of prevention and treatments, cardiovascular diseases (CVDs) remain a leading health burden, accounting for 32% of all deaths (World Health Organization. “Cardiovascular Diseases (CVDs).” WHO, February 1, 2017, https://www.who.int/news‐room/fact‐sheets/detail ...

Humidity Ramp Protocols Systematically Underestimate Human Heat Tolerance Limits

open access: yesSafety Science and Technology, EarlyView.
Short dwell times in humidity‐ramp protocols (Δt/τ≪1 ${\Delta }t/\tau \mathit{\ll }1$) prevent human core temperature from reaching equilibrium, causing premature inflection points and systematic underestimation of critical environmental limits by ∼3°C–4°C.

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.

Mercury Precession- A Call for Research into Electromagnetic Mechanisms

open access: yes
AbstractThe anomalous perihelion precession of Mercury, measured at ~43arcseconds per century, is widely regarded as one of the three classic proofs of Einstein's General Theory of Relativity (GR). The prevailing interpretation attributes this precession to the curvature of spacetime around the Sun, as described by the Schwarzschild metric.

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.
