Mechanistic Insights into a Synergistic FeOx/Fe‐N4 System for Practical Nitrate Abatement with Value‐Added Ammonia Recovery

open access: yesAdvanced Functional Materials, EarlyView.
This work provides a novel interpretation of the nitrate reduction mechanism on iron oxides (FeOx) by employing constant‐potential density functional calculations and reports the design and synthesis of a robust and high‐performance Fe3O4/Fe‐N4‐C catalyst with remarkable Faradaic efficiency, current density, and stability under practical reaction ...

Benefit Transfer over Time of Ecosystem Values: the Case of Forest Recreation [PDF]

open access: yes
We conduct a functional benefit transfer over 20 years of total willingness to pay based on car-borne forest recreation in 52 forests, using a mixed specification of a random utility model and geographic information systems to allow heterogeneous ...

A Computational Journey Toward an Optimal Design for Metamaterial Epicardial Passive Sleeves

open access: yesAdvanced Healthcare Materials, EarlyView.
Passive epicardial sleeves are evaluated in 3D in‐silico heart models to reveal how sleeve geometry, stiffness, anisotropy, and metamaterial architecture influence cardiac mechanics after myocardial infarction. A continuum‐to‐auxetic design exploration shows that region‐specific mechanical engagement can reduce infarct bulging and modulate torsional ...

ESTIMATING THE OPPORTUNITY COST OF RECREATION TIME IN AN INTEGRABLE 2-CONSTRAINT COUNT DEMAND MODEL [PDF]

open access: yes
How researchers treat the opportunity cost of time substantially influences recreation demand parameter and welfare estimates. This paper presents a utility-theoretic and implementable approach, estimating the shadow value of time jointly with recreation

What is the place of democracy in recreation ecology? [PDF]

open access: yes, 2008
What should be monitored and who decides has been debated for as long as recreation ecology has been with us. The early work on planning frameworks advocates consulting with visitors to determine what conditions are important to them and then derive ...

Effect of 2D and 3D ECM and Biomechanical Cues on Human iPSC‐Derived Liver Progenitor Cell Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
An engineered microtissue model is developed and optimized to investigate human liver development. Extracellular matrix composition and mechanical forces are tuned using high‐throughput assays. Human induced pluripotent stem cells serve as the cellular source, enabling the observation of de novo patterned differentiation.

Tourism potential of the Belarusian province (sociological analysis)

open access: yesВестник Майкопского государственного технологического университета
Introduction. In the Republic of Belarus special attention is paid to the development of the tourism potential of provincial regions. This is due to the fact that, on the one hand, they have large recreational resources, on the other hand, they are in a ...

A Human Neural Tube Model Using 4D Self‐Folding Smart Scaffolds

open access: yesAdvanced Healthcare Materials, EarlyView.
Induced pluripotent stem cells (iPSCs) exhibit features comparable to the inner cell mass of the human embryo. iPSCs are applied to a novel self‐folding 4D‐Neural Tube (4D‐NT) structure that mimics the neurulation process. This 4D‐NT model recapitulates early events of human neural development and represents a platform to explore neurodevelopmental ...
