Multi‐Physics Pinhole Size Tolerance Analysis on the Leakage Characteristics and Performance of Proton Exchange Membrane Fuel Cells

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT This study delves into exploring how pinhole size affects both the electrochemical efficiency and hydrogen leakage within proton exchange membrane fuel cells (PEMFCs). The researchers devised a comprehensive multiphysics field model for the PEMFC and employed the finite element method to simulate various pinhole diameters, evaluating their ...

Direct Assembly of Micrometer‐Long Polymeric Cylinders in Water via Supramolecular Sticker Engineering

open access: yesMacromolecular Rapid Communications, EarlyView.
Engineering order at the nanoscale: Tailored design of PDI and TEG‐functionalized poly(N,N‐dimethylacrylamide) enables direct assembly of micrometer‐long nanocylinders in water. TEG prevents clustering, while the polymer chain length governs the morphology.

A Novel Approach to Lithium Extraction From Spodumene by Combining Maleic Acid Leaching and Cyanex 936P Solvent Extraction

open access: yesMetalMat, EarlyView.
Hydrometallurgical flowsheet to extract lithium from spodumene by combining leaching with maleic acid and solvent extraction with Cyanex 936P. ABSTRACT This paper explores a novel approach to lithium recovery from spodumene, a lithium‐bearing mineral. Instead of traditional sulfuric acid leaching, organic acids—specifically maleic acid—are investigated

First-order regularity of convex functions on Carnot Groups [PDF]

open access: yes, 2018
We prove that h-convex functions on Carnot groups of step two are locally Lipschitz continuous with respect to any intrinsic metric. We show that an additional measurability condition implies the local Lipschitz continuity of h-convex functions on ...

Autonomous Artificial Molecular Motors and Pumps

open access: yesChemSystemsChem, EarlyView.
Autonomous energy consumption is the only way to introduce molecular motors into more sophisticated, larger systems, capable of life‐like behavior. We reviewed a selection of the most recent advances in the field molecular motors focusing on those capable of performing continuous and autonomous motion under constant experimental conditions, that is ...

Defining Treatment‐Resistant Bipolar Depression: Recommendations From the ISBD Task Force

open access: yesBipolar Disorders, EarlyView.
ABSTRACT Objective Despite the availability of approved treatments, a substantial proportion of patients with bipolar disorder experience treatment‐resistant bipolar depression (TRBD), characterized by persistent depressive symptoms unresponsive to standard therapies. However, a universally accepted definition of TRBD is lacking.

Lipschitz and bilipschitz maps on Carnot groups [PDF]

open access: yesPacific Journal of Mathematics, 2013
Suppose A is an open subset of a Carnot group G, where G has a discrete analogue, and H is another Carnot group. We show that a Lipschitz function from A to H whose image has positive Hausdorff measure in the appropriate dimension is biLipschitz on a subset of A of positive Hausdorff measure.

Adherence to Treatment in Allergic Rhinitis During the Pollen Season in Europe: A MASK‐air Study

open access: yesClinical &Experimental Allergy, Volume 55, Issue 3, Page 226-238, March 2025.
In a study assessing mobile health data, (i) adherence to rhinitis medication was highest for oral antihistamines and lowest for azelastine‐fluticasone, (ii) in weeks of partial adherence, azelastine‐fluticasone was associated with lower levels of reported rhinitis symptoms than other medication classes.

Time to prerandomization seizure count design sufficiently assessed the safety and tolerability of perampanel for the treatment of focal seizures

open access: yesEpilepsia, EarlyView.
Abstract Objective In traditionally designed randomized clinical trials of antiseizure medications, participants take a blinded treatment for a prespecified number of weeks, irrespective of continued seizures. The alternative design time to prerandomization monthly seizure count (T‐PSC) allows participants to end the blinded treatment after an ...
