Intrinsically Cross‐Linked ECM‐Like Multilayers for BMP‐2 Delivery Promote Osteogenic Differentiation of Cells

open access: yesAdvanced Materials Interfaces, 2023
Surface coatings prepared by layer‐by‐layer technique permit loading of growth factors (GFs) and their spatially controlled release. Here, native chondroitin sulfate (nCS), oxidized CS (oCS100), or mixture of both (oCS50) are combined with collagen I ...

Assessing the degradation pattern and mechanism of membranes in polymer electrolyte membrane fuel cells using open-circuit voltage hold and humidity cycle test protocols

open access: yesMaterials Science for Energy Technologies, 2022
As the degradation of polymer electrolyte membranes (PEMs) shows catastrophic failures with pinholes and cracks, studies on PEM degradation are essential to improve the reliability and lifetime of polymer electrolyte membrane fuel cell (PEMFC) membrane ...

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

open access: yesAdvanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Operando Visualization of Cathode Water Management in Proton Exchange Membrane Water Electrolyzers Using Synchrotron X‐Ray Radiography

open access: yesAdvanced Science, EarlyView.
The cathode of proton exchange membrane water electrolyzers remains a poorly understood region despite its importance for hydrogen purity and operational safety. Operando synchrotron X‐ray radiography directly visualizes liquid water behavior and uncovers a transition from continuous to pulsating transport, providing new insight into multiphase ...

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

Polyelectrolyte Multilayer: Caged PTFE Particles in Water for Continuous, Sonochemical H2O2 Synthesis

open access: yesAdvanced Science, EarlyView.
A yolk–shell PTFE‐based composite (YSP) enables tunable, robust hydrophobic–water interfaces for efficient, on‐demand sonocatalytic H2O2 generation and pollutant degradation. ABSTRACT The use of polytetrafluoroethylene (PTFE) particles to promote sonochemical H2O2 production has attracted growing interest, as cavitation bubbles formed at or near their ...

Emission testing of diesel multiple units complying with different emission standards during real operating conditions

open access: yesPojazdy Szynowe
This article presents comparative studies on pollutant emissions from railbuses meeting different emission standards (Stage IIIA and Stage IIIB). Measurements were conducted under real-world operating conditions on routes regularly serviced by the tested

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.
