Oxygen reduction performance measurements: Discrepancies against benchmarks
نویسندگان
چکیده
Oxygen electrocatalysis is crucial for renewable energy conversion and storage technologies. Specifically proton exchange membrane fuel cells (PEMFCs), oxygen reduction reaction (ORR) the primary that determines performance costs. The ORR activity durability are commonly assessed using a rotating disk electrode (RDE). However, there numerous inconsistencies in RDE measurements among researchers when comparing newly developed catalysts to state-of-the-art ones. These evaluation deviations from standard protocols result irreproducible screening benchmarking of electrocatalysts. Despite fact US Department Energy has established regularly revises protocols, many reported studies do not adhere these guidelines. This perspective aims draw attention discrepancies stability at as emphasizes implementing mandatory meaningful comparison durability. We intend emphasize use available test standards ubiquitously more accurate comparisons accelerate development cell catalysts.

Benchmarks from Reduction Finding
Consider the problem of searching for a complexity-theoretic reduction between two decision problems, P and Q. Such a reduction is a function r satisfying x ∈ P ⇐⇒ r(x) ∈ Q for all structures x for which it makes sense to consider P . It is not difficult to show that determining the existence of reductions is undecidable in general. However, sufficiently restricting the class of reductions and ...
متن کاملDiscrepancies in Communication Versus Documentation of Weight-Management Benchmarks
To examine gaps in communication versus documentation of weight-management clinical practices, communication was recorded during primary care visits with 6- to 12-year-old overweight/obese Latino children. Communication/documentation content was coded by 3 reviewers using communication transcripts and health-record documentation. Discrepancies in communication/documentation content codes were r...
