Rounded Monodisperse Fluorescent Nanodiamonds

Small, EarlyView.
Nanodiamond (ND) shape control using rapid molten‐nitrate etching is studied as a scale‐up method for monodispersed rounded particles. Optimal etching condition (567°C for 6 min) yields NDs with atomically stepped surfaces and reduced sp2 content. Compared to angular control, rounded NDs exhibit an increased proportion of luminescent particles (66% vs.

Caddo Ceramic Vessels from the McSpadden Site

Index of Texas Archaeology Open Access Grey Literature from the Lone Star State, 2014
The McSpadden site (unrecorded and with no site trinomial) is located on the outskirts of Frankston, Texas, in Anderson County, where three Caddo vessels were recovered during the construction of a local roadway during the early 1950s. These vessels are currently curated in a private collection in College Station, Texas.

Investigating the Iron‐Steam Process for Coupling With SOEC and SOFC: A Step Toward Integrated Hydrogen and Electricity Storage

steel research international, EarlyView.
Fixed‐bed reactor experiments (10 L) validate the iron–steam redox process, bridging material‐scale research and industrial power‐to‐power applications. Coupled with SOEC/SOFC systems, this framework defines critical interfaces for heat and gas management. Results confirm reproducible hydrogen storage and release, demonstrating technical feasibility at

Effective Equilibrium Reaction Zone Modeling of Hydrogen Plasma Smelting Reduction: A Scenario Analysis

steel research international, EarlyView.
The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

LIGHTING OF NEOLITHIC CERAMIC VESSEL IN A MUSEUM EXHIBITION

Transaction Kola Science Centre
The purpose of the article is to substantiate the need for a certain method of lighting a ceramic vessel of the Neolithic era, for the most reliable perception of not only its shape and decor, but also the meanings of the cultural heritage that were invested in it by its creators and users as bearers of a certain culture.
