Oxygen Evolution Reaction by Ni‐Hexacyanoferrates Nanocubes Integrated with Trigonal Selenium: Effect, Properties and Performances

open access: yesAdvanced Functional Materials, EarlyView.
This work describes a novel approach to obtain composite submicrometric structures of nickel hexacyanoferrate integrating trigonal selenium with the aim of enhancing the catalytic efficiency in oxygen evolution reaction (OER). Interestingly, the nanostructures undergo a cube‐to‐sphere transition that optimizes surface properties, leading to superior ...

Exploring CP Violation and $\eta$-$\eta'$ Mixing with the $B^0_{s,d} \to J/\psi \eta^{(\prime)}$ Systems

open access: yes, 2011
The $B^0_{s,d} \to J/\psi \eta^{(\prime)}$ decays provide new terrain for exploring CP violation. After briefly discussing $\eta$-$\eta'$ mixing, we analyse the effective lifetimes and CP-violating observables of the $B_s$ channels, which allow us to ...

Observation of the B-s(0) -> eta 'eta ' Decay

open access: yes, 2015
The first observation of the B-s(0) -> eta'eta' decay is reported. The study is based on a sample of proton-proton collisions corresponding to 3.0 fb(-1) of integrated luminosity collected with the LHCb detector. The significance of the signal is 6.4 standard deviations. The branching fraction is measured to be [3.31 +/- 0.64(stat) +/- 0.28(syst) +/-

Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

open access: yesAdvanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...

Single‐Step Electrochemical Battery Recycling

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates the use of single‐step recovery, an electrochemical process combining electrodeposition and electro‐dissolution, to recover lithiated transition metal oxides (LTMOs). The batteries produced through this recycling method perform similarly to batteries made from pristine materials.

Differentiating the Synergistic Interactions Between Li+ Salts and Cyclic to Linear Carbonate Ratios to Enable Wide‐Temperature Performance of Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The coordination in carbonate solvents and degradation products of lithium difluoro(oxolato) borate (LiDFOB) salt enables sufficient passivation of both LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode and graphite anode in the absence of ethylene carbonate (EC).
