4,4′-Dicyano- versus 4,4′-Difluoro-BODIPYs in Chemoselective Postfunctionalization Reactions: Synthetic Advantages and Applications
(American Chemical Society, 2023-04)
The presence of F or CN substituents at boron in BODIPYs causes a dramatic effect on their reactivity, which allows their chemoselective postfunctionalization. Thus, whereas 1,3,5,7-tetramethyl B(CN)2-BODIPYs displayed ...
Improving the Recyclability of an Epoxy Resin through the Addition of New Biobased Vitrimer
(MDPI, 2023-09-12)
In recent decades, the use of thermoset epoxy resins (ER) has spread to countless applications due to their mechanical properties, heat resistance and stability. However, these ERs are neither biodegradable nor recyclable ...
Hydrogel-Core Microstructured Polymer Optical Fibers for Selective Fiber Enhanced Raman Spectroscopy
(MDPI, 2021-03-06)
A new approach of Fiber Enhanced Raman Spectroscopy (FERS) is described within this article based on the use of Hydrogel-Core microstructured Polymer Optical Fibers (HyC-mPOF). The incorporation of the hydrogel only on the ...
Tough Hydrogels Based on Maleic Anhydride, Bulk Properties Study and Microfiber Formation by Electrospinning
(MDPI, 2021-03-22)
Hydrogels present a great number of advantages, such as their swelling capacity or their capability to mimic tissues, which make them very interesting biomaterials. However, one of their main disadvantages is their lack ...
Digital Quantum Rabi and Dicke Models in Superconducting Circuits
(Nature Publishing Group, 2014-12-15)
We propose the analog-digital quantum simulation of the quantum Rabi and Dicke models using circuit quantum electrodynamics (QED). We find that all physical regimes, in particular those which are impossible to realize in ...
The Forbidden Quantum Adder
(Nature Publishing Group, 2015-07-08)
Quantum information provides fundamentally different computational resources than classical information. We prove that there is no unitary protocol able to add unknown quantum states belonging to different Hilbert spaces. ...
Biomimetic Cloning of Quantum Observables
(Nature Publishing Group, 2014-05-09)
We propose a bio-inspired sequential quantum protocol for the cloning and preservation of the statistics associated to quantum observables of a given system. It combines the cloning of a set of commuting observables, ...
Energy Consumption for Ion-Transport in a Segmented Paul Trap
(IOP Publishing LTD, 2018-06-12)
There is recent interest in determining energy costs of shortcuts to adiabaticity (STA), but different definitions of ' cost' have been used. Wedemonstrate the importance of taking into account the control system (CS) for ...
Advanced-Retarded Differential Equations in Quantum Photonic Systems
(Nature Publishing Group, 2017-02-23)
We propose the realization of photonic circuits whose dynamics is governed by advanced-retarded differential equations. Beyond their mathematical interest, these photonic configurations enable the implementation of quantum ...
Quantum illumination reveals phase-shift inducing cloaking
(Nature Publishing, 2017-08-24)
In quantum illumination entangled light is employed to enhance the detection accuracy of an object when compared with the best classical protocol. On the other hand, cloaking is a stealth technology based on covering a ...
