Direct Relationship between Dispersion and Crystallization Behavior in Poly(ethylene oxide)/Poly(ethylene glycol)-g-Silica Nanocomposites
(American Chemical Society, 2021-02-08)
The inclusion of polymer-grafted nanoparticles (PGNPs) can impart various
functional properties to polymer nanocomposites (PNCs). For semicrystalline
polymers, we can control the spatial dispersion of PGNPs and presumably ...
Simulating Vibronic Spectra without Born-Oppenheimer Surfaces
(ACS Publications, 2021-04-01)
We show how linear vibronic spectra in molecular systems can be simulated efficiently using first-principles approaches without relying on the explicit use of multiple Born-Oppenheimer potential energy surfaces. We demonstrate ...
A microfluidic column of water index-matched packed microspheresfor label-free observation of water pollutants
(Springer Nature, 2021-03-28)
A microfluidic, label-free optical sensor for water pollutants, which is based on a packed micro-column of microspheres with refractive index similar to that of water, is presented. The perfluoropolyether microspheres are ...
Regulating Grip Forces through EMG-Controlled Protheses for Transradial Amputees
(MDPI, 2021-11-25)
This study aims to evaluate different combinations of features and algorithms to be used in the control of a prosthetic hand wherein both the configuration of the fingers and the gripping forces can be controlled. This ...
High-Harmonic Generation from Spin-Polarised Defects in Solids
(Nature, 2020-01-31)
The generation of high-order harmonics in gases enabled to probe the attosecond electron dynamics in atoms and molecules with unprecedented resolution. Extending these techniques to solids, which were originally developed ...
Building synthetic simulated environments for configuring and training multi-camera systems for surveillance applications
(SciTePress, Science and Technology Publications, Lda, 2021)
[EN] Synthetic simulated environments are gaining popularity in the Deep Learning Era, as they can alleviate the
effort and cost of two critical tasks to build multi-camera systems for surveillance applications: setting ...
Impact of MOF-5 on pyrrolidinium-based poly(ionic liquid)/ionic liquid membranes for biogas upgrading
(ACS, 2019-12-03)
Bearing in mind that Metal Organic Frameworks (MOFs) have remarkable CO2 adsorption selectivity and Mixed Matrix Membranes (MMMs) have been identified as potential solution for advancing the current state of the art of ...
Reviewing in situ analytical techniques used to research Martian geochemistry: From the Viking Project to the MMX future mission
(Elsevier, 2022-03-08)
[EN] The study of space has always been a field of great interest and thus space missions are becoming more and more ambitious with time. Therefore, with the 50th anniversary of the first spacecraft to land on Mars, a ...
Electronic Decoupling of Polyacenes from the Underlying Metal Substrate bysp(3)Carbon Atoms
(Nature, 2020-09-15)
Many organic molecules exhibit interesting electronic and magnetic properties, but as they are deposited onto a metallic substrate, their hybridisation often impacts on the observed characteristics. Here, the authors report ...
Giant Exciton Mott Density in Anatase TiO2
(American Physical Society, 2020-09-10)
Elucidating the carrier density at which strongly bound excitons dissociate into a plasma of uncorrelated electron-hole pairs is a central topic in the many-body physics of semiconductors. However, there is a lack of ...
