Thermoelectric Properties of a Family of Benzodifuranone‐Based Conjugated Copolymers in Oriented Thin Films Doped Sequentially With NDMBI‐H

open access: yesAdvanced Electronic Materials, EarlyView.
Combining high polymer orientation of n‐type copolymers by temperature rubbing and sequential doping with N‐DMBI results in a strong improvement of electrical conductivity and thermoelectric power factors reaching up to 9.8 ± 1.6 S cm−1 and 8 ± 3 µW m−1.K2, respectively.

Aura, vita, morte

open access: yesRivista di estetica, 2013
The essay concerns the relationship between the notion of aura and the notion of digital image. The digital image is not simply image-of, not only mimesis of an, identifiable or not, thing or image, and so it does not have a simulacral essence. On the other hand, it is not even an icon or an original image; it is rather a genetic relational form ...

The Haber Bosch Catalyst from Solid state Chemistry to Mesotechnology

open access: yesAdvanced Energy Materials, EarlyView.
A comprehensive, multi‐scale, multi‐modal study of the structural diversity of a technical multi‐promoted Haber Bosch catalyst for ammonia synthesis is provided. The different contributions of ammonia Fe are revealed and the presence of cement phases that have yet not been incorporated into discussions on the function of this catalyst system is shown ...

Novel Fe‐Modulating Raney‐Ni Electrodes toward High‐Efficient and Durable AEM Water Electrolyzer

open access: yesAdvanced Energy Materials, EarlyView.
Plasma spray (APS) is used to fabricate Fe‐modulated Raney‐Ni bifunctional electrodes for AEMWE. The resulting NFA‐CA exhibits distinct core–shell NiFe‐NiFe hydroxides, enabling 2 A cm⁻2 at 1.79 V—surpassing the U.S. Department of Energy's target for AWE systems—and demonstrates excellent durability with 1000 hours of stable operation at 1 A cm⁻2 ...

Suppressed Thermal Conductivity in van der Waals Semiconductor SnS2 by Stacking Engineering

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Achieving low thermal conductivity is crucial for materials used for thermoelectric energy conversion. It is demonstrated that the lattice thermal conductivity of van der Waals semiconductor SnS2 can be significantly reduced by introducing 2H and 4H structures stacked along the c‐axis.

Supply Constraints and Housing Prices [PDF]

open access: yes
This paper analyzes the effects of land use constraints on housing prices. We provide a new framework for evaluating policy when mobility across regions is allowed but limited.

Circularity, Sustainability, and the Quality of Coffee Sold via Vending Machines: What Do Italian Consumers Prefer?

open access: yesAgribusiness, EarlyView.
ABSTRACT Vending is an important sector in the daily lives of many people, and coffee is the most frequently consumed product in the European market. Like many other sectors, vending is responding to the challenge of sustainable development by taking various actions, such as offering increasingly ecologically sound coffee while maintaining/improving ...
