DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Verso il mondo nuovo. Ideologia della scienza nella serialità televisiva contemporanea = Towards the new world: the ideology of science in contemporary tv series

open access: yesH-ermes: Journal of Communication, 2016
The core of any story is constituted by a character who conflicts with someone or something to satisfy a desire. The core of any ideology is likewise oppositional, and it’s this stretch of antagonism which distinguishes what’s ideological from what it’s ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

De la modélisation fictionnelle à la modélisation scientifique à travers la lecture problématisée de l’album Plouf !

open access: yesRepères, 2012
This contribution is part of cross-disciplinary research on the use of children’s albums for science teaching sequences in primary schools. We refer to these albums as “realistic fiction” because of the omnipresent real world and of the implicit ...

Robust Electrocaloric Performance Enabled by Highly‐Polar Frustrated Nanodomains in NaNbO3‐Based Ferrodistortive Relaxor

open access: yesAdvanced Functional Materials, EarlyView.
P4bm framework in NaNbO3‐Ba(Ti, Hf)O3 ferrodistortive relaxor entails short‐range and highly‐polar ferrodistortive orders. The abundant highly‐polar orders facilitate to increase entropy change, and robust octahedral oxygen tilt enables to impede thermal perturbations.

Possible Worlds, Eutopias and Dystopias in some Contemporary Fictional Universes

open access: yesBetween
In this article, I examine the Possible Worlds Theory and its application to contemporary fictional universes, specifically focusing on eutopias and dystopias. I trace the historical development of the Theory from the 1970s.

What type of Science Communication best suits emerging countries? [PDF]

open access: yesJCOM: Journal of Science Communication, 2005
If we wish to attempt an initial analysis of the inquiry on the communication of science in Brazil, India and China that JCOM proposed in its three most recent issues, we should paraphrase Chinese science and science-fiction writer, Yan Wu: even though ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

open access: yesAdvanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...
