Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process

open access: yesCarbon Energy, EarlyView.
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Unbound Intrinsic Formation Clearance of 6β‐Hydroxycortisol Is a Useful Biomarker of CYP3A4 Activity during Pregnancy

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Pregnancy results in multiple physiological changes that impact drug disposition. For example, hepatic CYP3A activity and renal transporter‐mediated clearance increase in late pregnancy, but the time course of these changes across pregnancy is not known.

Solvation Engineering with 2D Laponite Nanosheets for Stable Aqueous Zinc‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, ZBL was introduced as an electrolyte additive to the ZnSO4 electrolyte to achieve more uniform Zn plating/stripping and reduce side reactions, thereby improving the reversibility of Zn anodes. This leads to enhanced cycling stability in both symmetric and full cells.
