Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

open access: yesAdvanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

RESPUESTA DE TEJIDOS EMBRIOGENICOS DE ÑAME (Dioscorea alata var. “Pico de botella”) A Colletotrichum gloeosporioides [PDF]

open access: yesTemas Agrarios, 2012
Yam tuber production has been affected for anthracnose, decreasing farmers´ incomes. Genetic resistance has been attempted; however, the species narrow genetic base favors fungal re-infection.

Real-time sampling of reasons for hedonic food consumption: Further validation of the Palatable Eating Motives Scale

open access: yesFrontiers in Psychology, 2015
Highly palatable foods play a salient role in obesity and binge-eating, and if habitually eaten to deal with intrinsic and extrinsic factors unrelated to metabolic need, may compromise adaptive coping and interpersonal skills.

posterior end mark 2 (pem-2),pem-4,pem-5, andpem-6: Maternal Genes with Localized mRNA in the Ascidian Embryo

open access: yesDevelopmental Biology, 1997
The posterior-vegetal cytoplasm of an ascidian egg contains maternal factors required for pattern formation and cell specification of the embryo. We report here the isolation and characterization of cDNA clones for novel maternal genes, posterior end mark 2 (pem-2), pem-4, pem-5, and pem-6. We obtained these clones from a cDNA library of Ciona savignyi

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Readability of Patient Educational Materials in English Versus Arabic

open access: yesHealth Literacy Research and Practice, 2019
Little research has been done about patient educational materials (PEMs) written in Arabic. Readability of Arabic PEMs has not previously been assessed because, until recently, there was no validated Arabic readability assessment tool.

Assessing the Functional Accessibility, Actionability, and Quality of Patient Education Materials from Canadian Cancer Agencies

open access: yesCurrent Oncology, 2023
Patient education materials (PEM)s were extracted from provincial cancer agencies to determine their organizational health literacy by evaluating the quality, actionability, and functional accessibility (e.g., readability and understandability) of their ...

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.
