The development of sustainable and lightweight composites addresses the critical need for environmentally benign materials. The introduction of fillers, such as carbon fibers (CFs), helped the development of high-performance, multifunctional, and more mechanically efficient composites. Most CF-reinforced composites rely on heavy chemicals or permanent matrix binders to ach…

Hydrogen (H2) exposure may alter cement properties and compromise wellbore integrity in underground hydrogen storage (UHS), yet the behaviour of cement systems designed for salt cavern environments remains poorly constrained. This study provides a systematic evaluation of H2-brine interactions in three cementitious materials: Salado micro-concrete (SMC), salt concrete (SAC…

Dual-fuel ammonia (NH3) combustion has been investigated as a promising way to meet the International Maritime Organization’s (IMO) CO2 reduction mandate for internal combustion engines in the maritime sector. High unburned NH3 emissions limit the replacement of the direct-injected diesel at low loads. One possible avenue to tackle this problem is to reform NH3 to hydrogen…

A dedicated Knowledge Management system is a critical component to ensuring the security of the transport of nuclear materials, specifically in mitigating disruptions to the supply chain. Knowledge Management within the nuclear sector focuses on the gathering and retention of knowledge and the updating of the existing knowledge base among staff (both tacit and implicit), a…

ORNL Report
Measuring the economic impact of a national laboratory requires recognizing that innovation-driven growth operates through both clearly quantifiable channels and broader, system-level effects that are more diffuse. This report presents ORNL’s economic impact in two complementary categories. First, the impact of ORNL’s spending—payroll, procurement, construction, and visito…

Observing fractionalized quasiparticles and their confinement into emergent bound states is a key focus of modern quantum magnetism. The quasi-one-dimensional frustrated antiferromagnet CuGeO3 undergoes a spin-Peierls transition to a low-temperature phase of spin singlet dimers. Here we observe an energy-dependent variation of quasiparticle character—from weakly interactin…

Human populations are projected to reach 10 billion by 2050, underscoring the growing importance of accurate population modeling. As modeling complexity increases, it necessitates the integration of a variety of data sources and methods. The resulting gridded population datasets show different levels of performance for different regions, possibly due to population characte…

Direct ink writing (DIW) of silicon carbide (SiC) enables the fabrication of net-shaped ceramic components, but achieving slurries with high solids loading is a challenge. In this work, we develop a monomodal, sub-micron SiC slurry by tuning colloidal interactions through zeta potential analysis, dispersant selection, and rheological characterization. A 2 vol% addition of…
