The potential land requirements and related land use change emissions of solar energy
(Nature, 2021-02-03)
Although the transition to renewable energies will intensify the global competition for land, the potential impacts driven by solar energy remain unexplored. In this work, the potential solar land requirements and related ...
Kinetics of NH3 Desorption and Diffusion on Pt: Implications for the Ostwald Process.
(American Chemical Society, 2021-10-21)
We report accurate time-resolved measurements of NH3 desorption from Pt(111) and Pt(332) and use these results to determine elementary rate constants for desorption from steps, from (111) terrace sites and for diffusion ...
Superconducting spintronic tunnel diode
(Nature, 2022-05-04)
Diodes are characterized by mono-directional flow of current, yet this simplicity belies their critical importance in electronics and optics. Here, Strambini et al demonstrate a superconducting quasi-particle equivalent, ...
The stochastic self-consistent harmonic approximation: calculating vibrational properties of materials with full quantum and anharmonic effects
(IOP Publishing Ltd, 2021-07-13)
[EN] The efficient and accurate calculation of how ionic quantum and thermal fluctuations impact
the free energy of a crystal, its atomic structure, and phonon spectrum is one of the main
challenges of solid state physics, ...
Selective ultrasensitive optical fiber nanosensors based on plasmon resonance energy transfer
(American Chemical Society, 2020-04-03)
The facet of optical fibers coated with nanostructures enable the development of ultraminiature and sensitive (bio)chemical sensors. The reported sensors until now lack of specificity and the fabrication methods offer poor ...
Homelessness and self-rated health: evidence from a national survey of homeless people in Spain
(BMC, 2019-08-10)
Background: Internationally, acute homelessness is commonly associated with complex health and social care needs. While homelessness can be understood as an outcome of structural housing exclusion requiring housing led ...
Quantum anharmonic enhancement of superconductivity in P63/mmc ScH6 at high pressures: A first-principles study
(AIP Publishing, 2021-11-05)
Making use of first-principles calculations, we analyze the effect of quantum ionic fluctuations and lattice anharmonicity on the crystal structure and superconductivity of P63/mmc ScH6 in the 100–160 GPa pressure range ...
Electrical Percolation in Extrinsically Conducting, Poly(εpsilon-Decalactone) Composite Neural Interface Materials
(Nature, 2021-01-14)
By providing a bidirectional communication channel between neural tissues and a biomedical device, it is envisaged that neural interfaces will be fundamental in the future diagnosis and treatment of neurological disorders. ...
Large Volume Self-powered Disposable Microfluidics by the Integration of Modular Polymer Micropumps with Plastic Microfluidic Cartridges
(ACS, 2020-12-10)
Microfluidic microsystems are often designed to analyse samples of small volume of fluid, however, some applications require the analysis of larger volumes. The ideal miniaturized microfluidic analytical device should be ...
On-demand generation and removal of alginate biocompatible microvalves for flow control in microfluidics
(Elsevier, 2016-10-29)
[EN] This paper describes, for the first time, the use of alginate hydrogels as miniaturised microvalves within microfluidic devices. These biocompatible and biodegradable microvalves are generated in situ and on demand, ...
