Annealing core@shell nanoparticles (NPs) yields high-entropy alloy NPs. Owing to their dispersed Pt/Pd content and low elemental diffusivity, they exhibit enhanced electrocatalytic performance durability for the oxygen reduction reaction.
Abstract Metal-oxide nanocrystals doped with aliovalent atoms can exhibit tunable infrared localized surface plasmon resonances (LSPRs). Yet, the range of dopant types and concentrations remains limited for many metal-oxide hosts, largely because difficulty in establishing reaction kinetics that favors incorporation by using co-thermolysis method. Here we develop cation-exchange reactions to introduce p-type dopants (Cu + , Ag etc.) into n-type nanocrystals, producing programmable LSPR...
A central theme of nanocrystal (NC) research involves synthesis dimension-controlled NCs and studyof size-dependent scaling laws governing their optical, electrical, magnetic, thermodynamic properties. Here, we describe the monodisperse CdO that exhibit high quality-factor (up to 5.5) mid-infrared (MIR) localized surface plasmon resonances (LSPR) elucidate inverse relationship between carrier concentration NC size. The LSPR wavelength is readily tunable 2.4 ∼6.0 μm by controlling size NCs....
ConspectusWhen combined with earth-abundant metals, Pt-based alloy nanoparticles (NPs) can be cost-effective electrocatalysts. However, these NPs experience leaching of non-noble-metal components under harsh electrocatalytic conditions. The Skrabalak group has demonstrated a novel NP construct in which random surfaces are stabilized against by their deposition onto intermetallic seeds. These core@shell highly durable electrocatalysts, the ability to tune catalytic performance architecture,...
The crystal structures of three β-halolactic acids have been determined, namely, β-chlorolactic acid (systematic name: 3-chloro-2-hydroxypropanoic acid, C 3 H 5 ClO ) (I), β-bromolactic 3-bromo-2-hydroxypropanoic BrO (II), and β-iodolactic 2-hydroxy-3-iodopropanoic IO (III). number molecules in the asymmetric unit each structure ( Z ′) was found to be two for I II, one III, making II isostructural III unique. difference between units is due direction hydrogen bond alcohol group a neighboring...
