Researchers utilized a roll-to-roll process to coat electrically conductive carbon fibers with semiconducting silicon carbide nanoparticles—demonstrating a scalable method to make reinforcing fibers for composite applications requiring strong
Scientists have unraveled details of the mechanism of mechanical reinforcement in glassy polymer nanocomposites.1 Measurements in the interfacial layer ~2–4 nm around nanoparticles revealed that Young’s modulus, which defines the relationship between
Concentrated transition metal alloys with the formula NiCoCrx, with x≈1, and a simple cubic crystal structure, display transport, magnetic and thermodynamic signatures exhibited by more structurally complex compounds near a quantum critical point (QCP).
Researchers have demonstrated a process to prepare morphologically tailored carbon materials with good electrochemical capacity and stability for sodium-ion battery anodes.
Misfit heterojunctions formed by van der Waals (vdW) epitaxial growth of one crystalline metal chalcogenide monolayer on another was demonstrated for the first time to form p-n junctions that exhibit a photovoltaic response.
Spatial localization of distinct photoexcited species were identified in light harvesting perovskite based materials using ultrafast transient absorption microscopy (TAM).
Thallium-doping (5%) of BaFe2As2 crystal causes a surprising rise of the antiferromagnetic transition temperature (TN), related to magneto-elastic coupling. This is the first example of the increase of TN with chemical doping in BaFe2As2.
Compositional complexity is found to strongly affect electrical, thermal, and magnetic properties of nickel-containing face-centered cubic concentrated alloys.
Researchers discovered that isolated platinum atoms in copper surfaces efficiently catalyze the selective hydrogenation of 1,3 butadiene, a reaction important for many industrial applications.1 A new generation of catalysts with one Pt atom for approximate
While palladium, a common catalyst, oxidizes easily, it has now been shown that palladium films grown on ruthenium are surprisingly inert to oxidation when they are thinner than six atomic layers.
The ability to control the binding strength of molecules t
