HRTEM Imaging and Mechanistic Insights Into Carbon Nanotube Nucleation and Growth on Fe Nanocatalysts in a Thermal Plasma

open access: yesSmall Methods, EarlyView.
Carbon nanotubes (CNTs) were successfully debundled from Tuball soots produced using iron nanocatalysts in arc discharge thermal plasma and distributed on monolayer graphene for HRTEM imaging for mechanistic insights into CNT synthesis. Zigzag single‐wall or double‐wall CNTs were identified.

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

open access: yessteel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

open access: yesArchaeometry, EarlyView.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

Peixe Zircon as a Quality Control Reference Material in U‐Pb Geochronology by LA‐ICP‐MS

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Peixe#0 zircon was characterised for U‐Pb geochronology using CA‐ID‐TIMS, SIMS and a long‐term LA‐ICP‐MS data set. The consistent results establish Peixe#0 as a reference material for U‐Pb quality control. Trace element heterogeneity requires careful, CL‐guided spot selection.

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Characterization of Lithia‐Based Machinable Glass‐Ceramic Materials

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective Lithia‐based glass ceramics lead the indirect single‐unit restoration market, but the underlying evidence is dominated by a single material. New materials have been introduced. The purpose was to investigate the elemental composition, elemental oxide composition, as‐fabricated surface morphology, as‐fabricated flexural strength ...

Paris Olympics and Paralympics: Insights from nationwide coordination in preparedness, supply chain management and blood inventory

open access: yesVox Sanguinis, EarlyView.
Abstract The Paris 2024 Olympic Games posed a unique challenge due to their scale, associated risks and the need for robust healthcare preparedness. This review outlines the forecasting and anticipatory measures taken by the Etablissement français du sang (EFS) to ensure a resilient blood supply chain throughout the event.

Insights from animal models: Dissecting the independent roles of oxygen and nutrients in the fetal origins of cardiovascular disease

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This review utilized animal models of complicated human pregnancies that result in reduced fetal nutrient or oxygen delivery, or combined nutrient and oxygen delivery, to elucidate their independent and/or synergistic contributions to the development of high‐risk cardiac phenotypes.

Bandgap‐Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton‐Coupled Electron Transfer for Stable Thermoelectrics

open access: yesAdvanced Electronic Materials, Volume 12, Issue 6, 23 March 2026.
Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120
