Mathematical modelling of the catalyst layer of a polymer-electrolyte fuel cell

open access: yes, 2007
In this paper we derive a mathematical model for the cathode catalyst layer of a polymer electrolyte fuel cell. The model explicitly incorporates the restriction placed on oxygen in reaching the reaction sites, capturing the experimentally observed fall ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

On Electrolytic Bubbles [PDF]

open access: yes, 2019
A better understanding of electrolysis-driven bubble evolution stages is provided: namely the nucleation, growth, and detachment. Superhydrophobic cavities were used to predefine the onset location of electrolytic bubbles on substrates. Using single and multiple superhydrophobic cavities on substrates allowed the elucidation of dissolved gas boundary ...

Predicting Electrolyte Conductivity Directly from Molecular-Level Interactions

open access: yes, 2022
Ionic conductivity is a fundamental property to evaluate an electrolyte blend’s per- formance. Though it is a macroscopic quantity, ionic conductivity is derived from molecular interactions including the stoichiometry and relative population of ion ...

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Homogeneous polymer-ionic solvate electrolyte with weak dipole-dipole interaction enabling long cycling pouch lithium metal battery

open access: yesNature Communications
Solid polymer electrolytes (SPEs) are considered as promising electrolytes for high-voltage lithium metal batteries. Whereas, the strong dipole-dipole interaction in polymer electrolytes limits the enhancement of the ionic conductivity.

Endogenous vasopressin and vasopressin receptor 2 in bladder as anti-diuretic / anti-spasmodic targets for the treatment of multifactorial nocturia

open access: yesContinence
Introduction: Nocturia, the urge to wake from sleep to void, is targeted sub-optimally by existing drugs that modulate circadian dysregulation of urine production in kidney without alleviating detrusor overactivity, a key aspect in the multifactorial ...

Electrolyte-Guided Design of Electroreductive CO Coupling on Copper Surfaces

open access: yes
Engineering the interfacial distribution of electrolytic ions can aid in modulating the electrocatalyst performance and efficiency. Using a hybrid quantum-classical modeling approach, we describe how predictive tuning of the solution microenvironment on ...

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Trial of Amiloride in Type 2 Diabetes With Proteinuria

open access: yesKidney International Reports, 2017
Renal sodium (Na+) retention and extracellular fluid volume expansion are hallmarks of nephrotic syndrome, which occurs even in the absence of activation of hormones that stimulate renal Na+ transporters. Plasmin-dependent activation of the epithelial Na+
