News authentication and tampered images: evaluating the photo-truth impact through image verification algorithms

Heliyon, 2020
Photos have been used as evident material in news reporting almost since the beginning of Journalism. In this context, manipulated or tampered pictures are very common as part of informing articles, in today's misinformation crisis.

Eco‐Designed Transparent Bacterial Cellulose Composites for Next‐Generation Opto‐Electronics

Advanced Optical Materials, EarlyView.
The developed transparent bacterial cellulose (BC) composite film using bio‐based resin results in higher transparency (89%) and lower haze (12%) at 550 nm, combined with insulative, hydrophobic and mechanically robust properties, thereby, enabling successful fabrication of an electrochromic device with efficient optical modulation on a sustainable ...

Calls to action and user engagement: The role of visual and verbal requests in nonprofit advocacy on Facebook

Computers in Human Behavior Reports
A common strategy to boost user engagement on social media is to incorporate requests into posts. While previous research has focused on the effects of direct verbal requests (i.e., commands), the role of subtler, indirect verbal and visual requests ...

Flexible and Scalable 2D/3D Tin‐Based Perovskite Photodetectors via Inkjet Printing

Advanced Optical Materials, EarlyView.
Lead‐free tin‐based perovskite films are successfully fabricated via scalable inkjet printing on rigid and flexible substrates. Incorporating high‐purity precursors and dual‐layer encapsulation minimizes defects and eliminates oxidation. The resulting photodetectors demonstrate high responsivity, persistent photoconductivity, and excellent 30 day ...

Confinement‐Induced Nonlocality and Optical Nonlinearity of Transdimensional Titanium Nitride Films in the Epsilon‐Near‐Zero Region

Advanced Optical Materials, EarlyView.
The epsilon‐near‐zero (ENZ) effect in metals emerges only in nanometer‐scale films with exceptional optical quality. Titanium nitride (TiN) films grown by molecular beam epitaxy retain high crystallinity down to 2 nm and exhibit dramatically enhanced nonlinear optical responses near the ENZ region.

Nanopatterned Dual‐Carbon‐Dot Photonic Films With Enhanced Light Outcoupling

Advanced Optical Materials, EarlyView.
Nanoimprinted dual‐carbon‐dot/PVA films combine composition‐tunable blue–green emission with grating‐mediated directional light outcoupling. Water‐processable B‐CD and G‐CD composites are patterned by drying‐assisted nanoimprinting, producing angle‐selective emission peaks that follow the first‐order diffraction condition and exhibit reference ...

Stirring‐Induced Modulation of NIR Emission in Tm3+‐Doped Nanoparticles: Evidence of Apparent Risetime Sensitivity

Advanced Optical Materials, EarlyView.
Motion was found to induce significant variation in the luminescence intensity ratio of NIR‐emitting Tm3+‐doped NaYbF4 nanoparticles, which has been ascribed to the population dynamics of the Tm3+ ion's excited states. These findings provide the groundwork for the design of motion nanosensors that can operate in environments not accessible with UV–vis ...
