Electrolyte‐Induced Cu+ Preservation Results in a Selectivity Switch of Electrocatalytic CO2 Reduction at a Copper‐Organic Framework as Electrocatalyst

Advanced Functional Materials, EarlyView.
The active role of KCl as a neutral electrolyte enables switching the selectivity on a Cu organic framework from C1 to C2+ products during electrocatalytic CO2 reduction. ABSTRACT We introduce a copper‐nicotinate (Cu‐NA) framework as a halogenide‐stabilized Cu+/Cu0 pre‐catalyst for electrocatalytic CO2 reduction with high C2+ selectivity in a “neutral”

Detailed mechanisms of hydrogen charging and hydrogen stress cracking of steel in liquid ammonia storage [PDF]

, 2019
The available polarisation curves of the literature are analysed in view of the theoretical analysis of the corrosive medium in Part I (J.-L. Crolet, Matériaux & Techniques 107, 401, 2019) and the new views on passivation and hydrogen charging.

Redirecting Nano‐Silicon Agglomeration: Dual‐Carbon Design Triggers Self‐Adaptive Nanoporous Si Sponge for Enhanced Lithium Storage

Advanced Functional Materials, EarlyView.
This study addresses silicon anode degradation using an engineered nSi/Gr/C dual‐carbon matrix. By restricting SEI infiltration, the architecture redirects silicon agglomeration into a beneficial structural self‐adaptive activation. During cycling, silicon nanoparticles self‐organize into a resilient nanoporous sponge. This dynamic network accommodates

Synthesis of AgBiS2 and AgInS2 Based on Formation Energies in Sulfur‐Rich Reducing Flame

Advanced Functional Materials, EarlyView.
High‐surface‐area AgInS2 and AgBiS2 nanoparticles were synthesized via enclosed flame spray pyrolysis by tuning flame conditions and formation energies to guide phase formation. Flame parameters were tuned to suppress oxides and enable pure sulfide phase growth.

Preventing hydrogen embrittlement in stainless steel by means of compressive stress induced by cavitation peening

The Journal of Engineering, 2015
In this paper, it has been demonstrated that compressive residual stress induced by cavitation peening which is one of the mechanical surface modification techniques can reduce invasion of the surface of austenitic stainless steel by hydrogen. Cavitation

Internal and surface damage after electrochemical hydrogen charging for ultra low carbon steel with various degrees of recrystallization [PDF]

, 2016
An ultra low carbon (ULC) steel was subjected to electrochemical hydrogen charging to provoke hydrogen induced damage in the material. The damage characteristics were analyzed for recrystallized, partially recrystallized, and cold deformed material.
