On the impact of capillarity for strength at the nanoscale

open access: yes, 2017
The interior of nanoscale crystals experiences stress that compensates the capillary forces and that can be large, in the order of 1 GPa. Various studies have speculated on whether and how this surface-induced stress affects the stability and plasticity ...

Tracking the Dynamic and Interactive Metal Oxidation Changes in CoFe, CoNi, and NiFe Bimetallic Hydroxides for Electrocatalytic Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Operando hard X‐ray absorption spectroscopy is applied to track the dynamic and interactive metal oxidation changes in iron group bimetallic hydroxides under different chemical and electrochemical conditions. It shows that Co and Fe oxidation are relatively equal and synchronized in CoFeOxHy.

Tailoring Microstructure in Copper‐Based Conductive Metal–Organic Frameworks for Enhanced Chemiresistive Sensing and Uptake of Sulfur Dioxide

open access: yesAdvanced Functional Materials, EarlyView.
Precursor‐ and solvent‐mediated synthesis yields four Cu3(HHTP)2 morphologies with distinct physicochemical, sorption, and sensing properties toward SO2. Uptake capacities correlate with BET surface area, while sensing performance scales with particle aspect ratio.

Investigating the Fatigue Response of Cathodically Charged Cold-Finished Mild Steel to Varied Hydrogen Concentrations

open access: yesCorrosion and Materials Degradation
This study investigates the fatigue behavior of cold-finished mild steel subjected to electrochemical hydrogen charging under controlled conditions. Samples were subjected to hydrogen charging at constant time in a fixed electrolyte pH, after which the ...

Raman structural studies of the nickel electrode [PDF]

open access: yes
Raman spectroscopy is sensitive to empirically controlled nickel electrode structural variations, and has unique potential for structural characterization of these materials. How the structure relates to electrochemical properties is examined so that the

Reducing Open‐Circuit Voltage Losses in Wide‐Bandgap FAPbBr3 Perovskite Solar Cells for Continuous Unassisted Light‐Driven Water Splitting

open access: yesAdvanced Functional Materials, EarlyView.
The combination of formamidinium thiocyanate and 1,3‐propane diammonium iodide for bulk and top‐surface passivation, and a ternary fullerene blend to improve energy band alignment, suppresses energy losses in wide‐bandgap FAPbBr3 perovskite solar cells.

Embrittlement behaviour of metal additive-manufactured high-entropy alloy components under gaseous and electrochemical hydrogen charging

open access: yesJournal of Materials Research and Technology
Embrittlement is an environmentally induced fracture that primarily affects metallic materials. This phenomenon occurs when hydrogen is absorbed on the metal surface and penetrates to the core, followed by degrading the mechanical properties in a ...

Positive electrodes of nickel-cadmium batteries [PDF]

open access: yes
Ni hydroxide sintered electrodes which are filled electrochemically are superior to chemically treated electrodes. In the electrochemical process, the hydroxide grows on the Ni grains and possesses a well-defined porous structure.
